Abstract. Most of architects and urban designers believe physical design gives
impact on our social life. For example, a sign or landmark in the middle of a city
makes people find orientation easier. In vice verse, most of social scientists believe
it is social dynamic that plays role in shaping our space. How people spend their
time moving from real space into cyber space is a proof that life style and IT give
impact to space usage. This paper argues that interaction between physical design
and social change is a two ways process. Both design aspect and social dynamic
influence each other. This paper aims to examine how designing of gated
community plays important role in increasing or decreasing segregation, both
spatially and socially. The paper explores some architectural design principles
applied in a gated community called Citra Land in west Surabaya, Indonesia, and
addresses segregation between Citra Landers and outside kampung. We find Citra
Land is designed openly and fully accessible for outsiders. It provides public spaces
and several accessible gates and streets without walls and fences making all places
inside and outside Citra Land spatially integrated. What’s interesting is it still
reinforces social segregation due to its policy on prohibiting using the public park.
We believe Citra Land’s planning and designing has successfully solved segregation
problem spatially not socially.

Socio-Cultural Impacts in the Formation of Urban
Village

E-mail: [email protected]
Abstract. In Indonesia, a group of village people tends to move from one place to
another and develops a living space to create a settlement. This research is conducted
by taking an example of a particular ethnic group that leaves the forestry area to a
new place in the city. After some time, this group of people creates a similar or
adapted socio-cultural system adapted from their origin place. The purpose of this
research is to examine the socio-cultural aspects that significantly influence the
emergence of urban village. This influence is interpreted as a social and cultural
relations with the establishment of space and significance of urban village. By
focusing on this issue, this research will trace the process of how a new and
unplanned settlement could emerge. The process and elements are indispensable
from social and cultural factors. Essentially, the shape of bulit space is a non
physical manifestation of local people which is established from time to time. In this
case, the research’s challenge lies on the circumstance in Indonesia where society
and culture influence the emergence of urban village. Physical apperance can be identified as a tipology of settlement and morphology of urban village.

Abstract. The architecture develops along with the development of human history.
So architecture is the field of study related to human physically and non-physically.
The development of architecture is a long process within the culture the architecture
develops. Physically, architecture has different shape from every historical phase.
The different shape has different historical background. The important building on
one period is always impressed.This impression still remains until now, in this
postmodern era. From the phenomena appear in architecture so this study focused
on the monumental buildings by analyzing the form of the building in this era. The
objects of the study are the buildings in Medan which represent the monumental
impression (Maimun Palace). The qualitative approach is applied to give more
knowledge in history, theory, and criticsm of architecture.The results of this study
described that the monumental impression of the object of study and forms of
building support that impression.

Abstract. The urban corridor is more than just a linear space to circulation. It is a
place for community activities. Since the urban area in Indonesia functionates
without guidelines, it is necessary to analyze how this space being used by the
community. The objective of the research is to explore the problems in utilization
of public space in Dr. Mansur corridor in Medan and to propose some
recommendation to improve it. The survey was started by mapping the physical
situation that based on urban design aspects and the activities occur. Based on the
data, the study identified the problems of the public space utilization. Next, study
selected several buildings that significant in generating public life. The study
interviewed the building's owners and users/customers to get their opinion and
perception about the using of urban public space utilization in the corridor in relation
to their private function. The study analyzed the problems and opportunity to
redesign the buildings that respect to public space. Then, the design ideas were
presented to the buildings owners to get their response. The result of the observation
shows that the fundamental problem in the corridor is the intervention of the private
interest to the street as public space. The study indicates that the majority of the
buildings owner was not aware that their buildings had distracted the urban public
space. However, they gave a positive respond to the design recommendation. The
design offered the solution that provided individual needs without intervention to
the public realm. The study can contribute to improving urban corridor by educating
the community with architecture and urban design.

Serdang Regency especially in Tembung village, PercutSei Tuan District.
Population structure in Tembung shows occurrence condition of rural-urban change
which seen from the sprawl land use change. The aim of the study is to reveal the
genius locus as one of land use change factors. The study conducted with
quantitative approach intended at obtaining variables which describing several
factors forming land use change. Descriptive approach intended to give an idea,
justification, and fact-finding with correct interpretation. Data collected through a
purposive sampling of 300 respondents who have built the house between 2010 till
2014. With overlay figure/ground technique, scoring analysis, descriptive
quantitative and SEM (Structural Equational Models) gained a result that place
character/genius locus (p=0,007) potentially as one of the main land use change
driving factors besides accessibility (p=0,039), infrastructure (p=0,005), social-
economic p=0,038). Topographic (p=0,663) was inversely potentially. The
implication of the findings is required intensive control in space utilization
considering the rapid change in land use transformation that tend to have the
negative impact of urban sprawl.

Abstract. This present time, Indonesia just began applying the concept of Green
Architecture. The actions require community participation as residents and the users
of the building. The built environment is designed around the idea of Green
Architecture but inhabited and managed improperly; the goal of sustainable built
environment is not achieved. The aspect of behaviour is the key factor in the
implementation of Green Architecture’s concept. This research is a descriptive
exploratory which is to identify the problems to the implementation of Green
Architecture’s concept in planned housing. Then the study will explore the
components causes of the problems used as a problem solver. The study conducted
on the living behaviour in CitralandBagya City’s resident. The estate is designed
and built with the concept of Green Architecture in Medan city. The research was
carried out by the four aspects of housing are the physical, social and cultural,
policy, and management issue. These three components will indirectly relate to the
economic issues that are the efficiency and effectiveness of living behaviour. The
results showed that the increasing of green behavior is still small and the occupant
requires motivation and socialization of living green.
Keywords: green architecture, living behaviour, planned settlement.

Abstract. Mebidangro is a metropolitan area in Sumatera Utara Province that
consists of some regencies and cities of Medan, Binjai, Deli Serdang, and Karo. The
region becomes one of the national strategic developments that have been assigned
by The President. In the planning, a part of the spatial arrangement refers to the role
of Kualanamu International airport as the international transportation hub.
Meanwhile, PT Angkasapura proposes the aerotropolis, a new town concept that
based on the strategic function of the airport. The model is derived from John
Kasada’s idea about the airport influence in generating and accelerating economic
activity in a “city airport.” The study aims to explore ideas on planning and design
a new town in Mebidangro that applies some aerotropolis theories, including spatial
structure, land use and urban design guidelines. The result of the study indicates that
aerotropolis can fit the vision of Mebidangro development in improving economic
activity as well as community quality of life. However, the implementation should
deal with some problems of land ownership and the community readiness. The
research can contribute to enrich the way to implement any “import” town planning and design theory that corresponds to local environment condition.

Abstract. Medan as one of the historical towns in Indonesia is rich with architectural
and urban heritages; however, there still has no integrated plan to safeguard them.
This paper discusses the cultural mapping of the seven heritage conservation
districts in the city of Medan. It focuses onexploring the process and challenges of
the study from the initial step of data collections to the building of the cultural maps
with web based GIS.Multi-method of data collection tactics or triangulation such as
field survey, interviews was done to cover the cultural data resources including both
tangible (or quantitative) and intangible (or qualitative). Participation of the local
community is essential to identify mainly the intangibles one. Based on the
preliminary analysis of the seven heritage districts in Medan city, Merdeka-
Kesawan area had whole categories of the cultural assets and resources compared to
other six heritage areas. Consequently, it influences the enhancement its cultural
heritage significance. By using our methods,we emphasized the importance of the
cultural mapping in preparing the conservation policies and strategies of the seven heritage districts in Medan.

Abstract. Japan face with many social and environmental problems especially
populationaging, social communication degradation and decreasing of agricultural
land. Kitakyushu city is one big city in Jpana, which the old people take 30% in
population, while younger people are moving to the big cities for working and other
desires. it is common that Japanese people is less and less communicate with other
people and tend to curl up in their personal space due to the modern stressful life.
Besides, a big ratio of Japanese farmers recently did not do the farm work anymore,
leading to a considerable abandoned agricultural land. So, there should be done to
improve the lives of older people, heal social communication, or revive the barren
land. The designing site is placed in Hibikino area, Kitakyushu city, Japan, a
farmland area operated by Japan Agriculture Association where citizens can hire
some slots to plant vegetables themselves. However, this placed does work
effectively when only a few people come to hire the land. This research method is
a descriptive study aimed to obtain qualitative data. The purpose of this study was
to create a design idea the agricultural community space where parents can work
and communicate with children, customers, and strangers with three targets of
sustainable environmental, social, and economic. And then, this system not only
helps to create the green lifestyle for inhabitant but also improves social
communication, reducing CO2emission with it sustainable working process.

Abstract. This paper investigates the changes of buildings and the patterns of spatial
use in the eastern corridor of Jl. Ir. H. Juanda Bandung. The aim is to what extent
the regulations related to floor-area ratio are implemented and how the space and
building looks are designed. Historically, the corridor of Jl. Ir. H. Juanda as part of
Dago area is designed for colonial residences, but the development of commercial
activities in the city of Bandung has resulted in many changes to the area, making it
a commercial area. This study used a descriptive qualitative method by conducting
field observations to identify buildings located on the eastern corridor which was
divided into three segments of the road. The results show that quantitatively the
buildings along the eastern corridor are still in compliance with the floor-area ratio.
There is only a small portion in the segment of between Jl. Cikapayang and Jl. RE
Martadinata that exceeds the ratio limit. However, the ration is not the only reference
to achieve the harmony in visual and the characters of the city. The characters of the
corridor are determined by several parameters, such as building height, building
scale and comparison visibility. These parameters should be put into consideration.
Thus, more detailed regulations regarding the changes in the shape, the pattern of use of space, and the concept of contextual design are highly required.

Islamic Modernism and Architectural Modernism of
Muhammadiyah’s Lio Mosque
Alfansyah Fauzy Prajawisastra, Tutin Aryanti
UniversitasPendidikan Indonesia, Bandung, Indonesia
E-mail: [email protected]
Abstract. The Muhammadiyah’sLio Mosque is one of the masterpieces of
AchmadNoe’man, the great Indonesian mosque architect. The mosque was built as
a community mosque at the center of Muhammadiyah’s quarter in Garut, West Java,
in conjuction with the construction of the district’s Muhammadiyah branch. Having
a shape out of the existing grip, the mosque has neither a dome nor a
tajugtumpangtiga (three-tiered pyramidal roof) like other mosques nearby, but
instead uses a gable roof and minarets towering. This article aims to analyze the
architecture of the Lio Mosque and to learn AchmadNoe’man’s interpretation of
modernism, both Islamic modernism and architectural modernism, reflected in the
mosque design. Employing a qualitative approach, this study used observation and
interviews with the mosque’s stakeholders. This article argues that the ideology of
modernism, believed by AchmadNoe’man and the Muhammadiyah organization,
was embodied in the Lio Mosque architecture.

The Salman Mosque: Achmad Noe’man’s Critique of
Indonesian Conventional Mosque Architecture
Asep Abdul Rahman Holik, TutinAryanti
Universitas Pendidikan Indonesia, Bandung, Indonesia
E-mail: [email protected]
Abstract. The Salman Mosque, designed by AchmadNoe’man, was a striking
Islamic architectural design in the 1960s when it was built. Unlike the conventional
mosques, particularly in Indonesia, it has no dome. Instead, the roof was made of
prestressed concrete and resembles a canoe. Using data drawn from field
observations, this paper explores the architectural characteristics of the Salman
Mosque as a product of Modern architecture. It argues that the domeless mosque,
the simple minaret, the wooden wall panels and floor, the women’s balcony, and the
roof demonstrate architectural modernism, as opposed to the conventional mosque
typology that flourished in Indonesia at the time. This paper further argues that the
Salman Mosque is Noe’man’s critique of the Indonesian conventional mosque
architecture. It concludes that the architectural features of the Salman Mosque reflects Noe’man’s modern vision of Islam and Islamic architecture.

E-mail: [email protected]
Abstract. The integrated kindergarten and elementary school is a public educational
facility used for early age and elementary education. Designated for children at 4-
12 years of age, the design should meet the standards and requirements, while
considering children’s needs in their development phase. This paper discusses the
design of an integrated kindergarten and elementary school using the playful theme.
Design was explored using LEGO and UNO-STACKO to create spaces that
accommodate material exploration for children. The design takes the play concept
as a medium of child’s learning in order to improve their ability and awareness of
the surrounding environment. The design translates the playful theme into imaginary
dimension, constructive-deconstructive shapes, and glide circulations concept. The
spatial pattern is applied by considering children’s behavior in the designated ages
to trigger their creativity improvement. The design is expected to serve as a model
of an integrated kindergarten and elementary school architecture.

E-mail: [email protected]
Abstract. Quba Mosque stands as it is today after being rebuilt and renovated
several times, as the sacred and historical place built by Prophet Muhammad PBUH
in the first day of his emmigration to Medina. Being the first architecture following
his hijra, it reflects the will of the people in their endowment to the mosque. This
paper aims at studying the changes throughout the development of the mosque,
focusing mainly on the last development designed by the architect El-Wakil, his will
to reforge the link between the past and the present and the significance of
understanding the Islamic culture, philosophy, and architecture. This study
employed a literature review to capture the mosque’s architectural features
developed by El-Wakil. It argues that the elements of the mosque, particularly the
domes, are products of El- Wakil’s vision and defence for traditionalism. His use of traditionalist approach shows his notion of what Islamic architecture is.

Abstract. A study of basidiomycetous fungi in decolorization of wastewater of
textile industry has been started in our laboratory. The objective of this study was to
obtain potential isolates and to examine their decolorization acitity. The fungi were
isolated from local forest, Gunung Barus Forest, in North Sumatera and screened
their ligninolytic activity qualitatively by bavendam method and the waste was
obtained from local textile industry in Medan. Nineteen fungal isolates grew on plate
agar medium containing 100% of waste supplemented with 2% glucose, and 6 of
those exhibited good growth when glucose in the media was reduced to 1%.
Surprisingly, these six potential isolates grew, although relatively at lower rate,
when glucose was not included in the media. Meanwhile, there was no substantial
decolorization of media could be observed on all plates cultures. Analyses of
decolorization on liquid condition containing 25% of wastewater and no glucose
showed that fungal grew at the bottom culture flask. All 6 isolates exhibited
decolorization activity. Interestingly, mass of mycelia growth at the bottom
absorbed dyes and dissolved suspended solid which was seemingly separated from
very clean solution medium surrounding. These results indicated that the cultures
utilized carbon source from waste and the extracellular matrixes produced by fungal
isolates might involve in decolorization of textile wastewater.

Abstract. The use of rice husk as adsorbent would not only reduce its disposal
problems, but would also produce value-added products, such as activated carbon
derived from rice husk. This study aimed to determine the optimum carbonization
temperature for activated carbon production from rice husk and its adsorption
performance on Pb in car battery wastewater. In this study, activated carbon was
produced by carbonizing rice husk 400–600 °C for 90–150 minutes followed by
chemical activation using 5% Na2CO3 and sieving to 100 meshes. Lead adsorption
was measured using atomic absorption spectroscopy (AAS). Results suggested that
highest carbon yield of 47.75% was obtained for carbonization at 500 °C for 150
minutes. At that condition, produced activated carbon contained 3.35% moisture,
30.86% ash, 18.04% volatile matter. The adsorption capacity was found to be

L × 40 cm H), and adding ALOF until moisture content (MC) in the range of 55-
65%. During composting, the MC was maintained at 55-65% range by adding the
ALOF. The turning frequency on each composter was varied i.e. once in every 1, 2,
3, 4, and 5 days. The parameters analysed during composting were temperature, pH,
MC, compost weight, water holding capacity (WHC), CN ratio, and the quality of
the final compost. Composting was carried out for 40 days and the best result
obtained at turning frequency was 3 days. The best compost characteristic was pH 9.0; MC 57.24%; WHC 76%; CN ratio 12.15%; P 0.58%; and K 0. 95%.

Abstract. This paper reports the performance and characterization of asymmetric
PVDF ultrafiltration flat sheet membranes with polyethylene glycol (PEG) of
different molecular weight as additives. The membranes were prepared via phase
inversion technique by using DMAc as solvent and polyethylene glycol with
molecular weights of 2000, 6000 and 20000 Da as additives in the dope formulation.
The performance of membrane was characterized using humic acid as natural
organic matter source. Membrane properties were evaluated in terms of pure water
flux, and humic acid rejection. The results indicated that the pure water flux of
membranes increased with the increase of PEG molecular weights. Fourier
transform infrared spectroscopy results revealed the presence of PEG in the
PVDF/PEG membrane with the significant appearance of the N-CH3 peak at 2877
cm-1. Scanning electron microscopy analysis was performed to investigate the
effects of additives on the morphological structure of the membrane. It was
disclosed that the porosity of the resulted membranes increased with the addition of
PEG.

Abstract. This study proposes a modification of polyethersulfone (PES) membrane
by blending the polymer with a hydrophilic additive of Brij-58. Flat-sheet PES
membrane was prepared through a non-solvent induced phase separation (NIPS)
method using dimethylformamide (DMF) as a solvent. PES membrane was
modified by adding Brij-58 into dope solution at a different concentration, i.e 1, 3,
5, 7, and 10 wt %. The fabricated membranes were characterized by means of
Scanning ElectronMicroscopy (SEM) and Fourier TransformInfra-Red (FTIR)
spectroscopy. Filtration performance of membrane was analyzed by using a dead-
end module. It is found that the addition of a small amount of Brij into polymer
solution brought about the increase of water flux. FT-IR investigation showed that
the additive exist on the surface of a blended membrane.

Abstract. Biodiesel is a promising energy alternative solution to cater the demand
of clean sustainable energy sources. Conventional biodiesel production is done by
transesterification method using stirred tank reactor and homogeneous base catalyst,
then followed by purification process. However, there are some drawbacks
associated with this method. They include soap formation, sensitivity to free fatty
acid (FFA) content and purification difficulties. Due to these downsides, biodiesel
production using heterogeneous acid catalyst in membrane reactor is proposed. This
project is aimed to study the effect of FFA content and membrane separation
effectiveness on FAME yield. Waste cooking oil, inorganic pressure-driven
membrane and WAl is used as raw material, membrane and heterogeneous acid
catalyst, respectively. Biodiesel yield formulation is derived from literature data and
then used in an Aspen HYSYS process simulation. Early phase cost estimation
shows that FFA content does not affect the estimated capital investment, while the
membrane separation effectiveness does significantly. Future work will include its
comparison with the conventional biodiesel production process.

Abstract. In this study, the roles of surface pores on membrane fouling was
investigated using three membranes in two lab-scale membrane bioreactors.
Characterization of the pristine membranes revealed that increasing polymer
concentration decreases pore sizes and porosity. Critical flux was found to decrease
with decreasing pore sizes. The finding was consistent for both MBRs. The results
of the long-term filtration were in agreement with the flux-stepping test. The fouling
layer was easily removed and only a few small particles remained as were observed
with scanning electron microscopy. Surface pore sizes and porosity declined for all
cleaned membranes, indicating permanent pore blocking, and the effect was higher
for membranes with larger pore size.

so the alpha cellulose extraction process of oil palm midrib greatly affect the quality
of the resulting microcrystalline cellulose. The purpose of this study was to compare
the microcrystalline cellulose produced from alpha cellulose extracted from oil palm
midrib by two different methods. Fisrt delignization method uses sodium hydroxide.
Second method uses a mixture of nitric acid and sodium nitrite, and continued with
sodium hydroxide and sodium sulfite. Microcrystalline cellulose obtained by both
method was characterized separately, including organoleptic test, color reagents
test, dissolution test, pH test and determination of functional groups by FTIR. The
results was compared with microcrystalline cellulose which has been available on
the market. The characterization results showed that microcrystalline cellulose
obtained by first method has the most similar characteristics to the microcrystalline
cellulose available in the market.

Abstract. The water repellent properties of red pepper seed oil (capsicol) have been
studied. The oil was coated on the glass surface by spray technique. Water repellent
properties were performed by measuring the contact angle of water droplets. The
measurement was conducted by varying the drying time of the oil coating at room
temperature. The optimum contact angle of the droplets on the glass with capsicol
coating is 46.77°, which can be achieved in 30 min of drying time. It also obtained
the smallest diameter of the droplets (0.47 cm). The longer drying time decrease the
contact angles and increases the diameter. The results were compared with the bare
glass and commercial water repellent. The contact angle of the droplets on the glass
surface with capsicol coating is higher than bare glass, but lower than glass with
commercial water repellent coating. It means that capsicol has the water repellent
properties.

Abstract. Curcumin is one of materials which have been widely used in medicine,
Asian cuisine, and traditional cosmetic. Therefore, understanding the stability of
curcumin has been widely studied. The purpose of this study was to investigate the
stability of curcumin solution against solar irradiation when making contact with
inorganic material. As a model for the inorganic material, titanium dioxide (TiO2)
was used. In the experimental method, the curcumin solution was irradiated using a
solar irradiation. To confirm the stability of curcumin when contact with inorganic
material, we added TiO2 microparticles with different concentrations. The results
showed that the concentration of curcumin decreased during solar irradiation. The
less concentration of curcumin affected the more decomposition rate obtained. The
decomposition rate was increased greatly when TiO2 was added, in which the more
TiO2 concentration added allowed the faster decomposition rate. Based on the result,
we conclude that the curcumin is relatively stable as long as using higher
concentration of curcumin and is no inorganic material existed. Then, the
decomposition can be minimized by avoiding contact with inorganic material.

Abstract. Red blood has been of great interest for scientists since it relates to
human’ and living creature’s life sustainability. One of the important compounds in
red blood is porphyrin. Here, the purpose of this study was to develop a method for
detecting porphyrin concentration using the assistance of giant magnetoresistance.
In short of the method, we added Fe3+ solution to the porphyrin, and the mixed
solution was introduced to the magnetic field. Next, the magnetized solution was
introduced to the magnetic sensor to indicate the existence of porphyrin in the
solution. To confirm the effectiveness of our method in detecting porphyrin, we
varied the flow rate and concentration of Fe3+-modified porphyrin solution. The
result showed that the more concentration and the slower flow rate affected the
higher sensitivity gained. Since this developed method is simple but effective for
detecting porphyrin concentration, we believe that further development of this
method will be benefit for many applications, specifically relating to the medical
uses.

Abstract. Clay is a type of soil which needs to be stabilized. The method often used
is stabilization by adding additive to the soil. In this study, the additive materials
that we use are volcanic ash from Mount Sinabung and rice husk ash. The selection
of these materials as additive is based on their silica content. Volcanic ash has a high
silica content that is equal to 82.04%, and rice husk ash also has a high silica content
which is equal to 89.8%. This study aims to improve the physical and mechanical
properties of soil. Clay used or this study was taken from Patumbak, Deli Serdang,
the volcanic ash was taken from Mount Sinabung, and the rice husk ash was
produced from the bricks burning outcome in Stabat Langkat. The tests for soil are
water content test, specific gravity test, Atterberg limits test, sieve analysis test,
compaction test, CBR (California Bearing Ratio) laboratory test, and Unconfined
Compression Test (UCT). The test results show that the value of liquid limit in
addition of volcanic ash and rice hush decreased gradually. So does the plasticity
index, the value decreased from 26.33% to 5.31% on the addition of 2.5% volcanic
ash + 22.5% rice husk ash. While on the mechanical properties, the optimal CBR
value obtained in the addition of 75% soil + 25% volcanic ash is 15.48%, and the
addition of 25% volcanic ash causes soil increases the compressive strength from
1.38 kg/cm2 to 2.23 kg/cm2. Unconfined Compression Test result shows that the
compressive Strength (qu) of original soil is 1.38 kg/cm² value, meanwhile the
Compressive Strength (qu) of remoulded soil is 0.58 kg/cm2.

Abstract. Paving block is one of the building materials used as the top layer of the
road structure besides asphalt and concrete. Paving block is made of mixed materials
such as portland cement or other adhesive materials, water and aggregate. In this
research, the material used as the additive of cement and concrete is volcanic ash
from Mount Sinabung, it is based on the results of the material testing, Sinabung ash
contains 74.3% silica (SiO2). The purpose of this research aims to analyze the
behavior of the paving blocks quality A and B with and without a mixture of
Sinabung ash, to analyze the workability of fresh concrete using Sinabung ash as an
additive in concrete, and to compare the test results of paving blocks with and
without using Sinabung ash. The samples that we made consist of four variations of
the concrete mix to experiment a mixture of normal sample without additive,
samples which are mixed with the addition of Sinabung ash 5%, 10%, 15%, 20%
and 25% of the volume of concrete/m3. Each variation consists of 10 samples of the
concrete with 28 days curing time period. We will do the compressive strength and
water absorption test to the samples to determine whether the samples are in
accordance with the type needed. According to the test result, paving blocks with
Sinabung ash and curing time reach quality A at 0%, 5% and 10% mixture with the
compressive strength of each 50.14 MPa, 46.20 MPa and 1.49Mpa, and reach
quality B at 15%, 20 %,25% mixture with curing time and 0%, 5%, 10%, 15%, 20%
and 25% mixture without curing time. According to the absorption values we got
from the test which are 6.66%, 6.73%, 6.88%, 7.03%, 7.09% and 7.16%, the entire
sample have average absorption exceeding SNI standardization which is above 6%
and reach quality C. Based on compressive strength and absorption data obtained
Sinabung ash can’t fully replace cement as the binder because of the low CaO
content.

Irregularities Using Pushover and Nonlinear Time
History Analysis
Daniel Rumbi Teruna1 1Lecturer, Department of Civil Engineering, University of Sumatera Utara
E-mail: [email protected]
Abstract. Pushover analysis or also known as nonlinear static procedures (NSP)
have been recognized in recent years for practical evaluation of seismic demands
and for structural design by estimating a structural building capacities and
deformation demands. By comparing these demands and capacities at the
performance level interest, the seismic performance of a building can be evaluated.
However, the accuracy of NSP for assessment irregular building is not yet a fully
satisfactory solution, since irregularities of a building influence the dynamic
responses of the building. The objective of the study presented herein is to
understand the nonlinear behaviour of six story RC building with mass
irregularities at different floors and stiffness irregularity at first story (soft story)
using NSP. For the purpose of comparison on the performance level obtained with
NSP, nonlinear time history analysis (THA) were also performed under ground
motion excitation with compatible to response spectra design. Finally, formation
plastic hinges and their progressive development from elastic level to collapse
prevention are presented and discussed.

Abstract. UDP drops packet when checksum bits in header does not match the
checksum bits calculated from the receive data. UDP-Lite improves UDP by using
partial checksum coverage. However, checksum error in both UDP and UDP-Lite
headers is potentially leading to wrong decision in dropping part(s) of packet. This
article proposes protocol to avoid the problem by using Forward Error Correction
(FEC) code to protect checksum bits. The evaluation results show that the number
of the received bytes increases up to 0.3% compared to UDP-Lite, which leads to 3
dB increment of the received image quality.

Abstract. “Big Graph Mining” is a continuously developing research that was
started in 2009 until now. After 7 years, there are many researches that put this topic
as the main concern. However, there is no mapping or summary concerning the
important issues and solutions to explain this topic. This paper contains a summary
of researches that have been conducted since 2009. The result is grouped based on
the algorithms, built system and also preprocess techniques that have been
developed. Based on survey, there are 11 algorithms and 6 distributed systems to
analyse the Big Graph have been improved. While improved pre-process algorithm
only covers: sampling and compression technique. These improving algorithms are
usually aimed to frequent sub graphs discovery, whereas slightly those of is aimed
to cluster Big Graph, and there is no algorithm to classify Big Graph. As a
conclusion of this survey, there is a need for more researches to be conducted to
improve a comprehensive Graph Mining System, especially for very big Graph.

Abstract. A rule-based system is prone to conflict as new knowledge every time
will emerge and indirectly must sign in to the knowledge base that is used by the
system. A conflict occurred between the rules in the knowledge base can lead to the
errors of reasoning or reasoning circulation. Therefore, when added, the new rules
will lead to conflict with other rules, and the only rules that really can be added to
the knowledge base. From these conditions, this paper aims to propose a conflict
resolution strategy for a medical debriefing system by analyzing scenarios based
upon the runtime to improve the efficiency and reliability of systems.

Abstract. The development of radar technology has an important role in several
fields such as aviation, civil engineering, geology, and medicine. One of the
essential components of the radar system is the antenna. The bandwidth can specify
the resolution of the radar. The wider the bandwidth, the higher the resolution of
radar. For Ground penetrating radar (GPR) or medical applications need with a
high-resolution radar so it needs an antenna with a wide bandwidth. In addition, for
the radar application is required antenna with directional radiation pattern. So, we
need an antenna with wide bandwidth and directional radiation pattern. One of
antenna that has meet with these characteristics is Vivaldi antenna. In previous
research, has designed several Vivaldi micro strip antenna for ultra-wideband radar
applications which has a working frequency of 3.1 to 10.7 GHz. However, these
studies there is still a shortage of one of them is the radiation pattern from lowest to
highest frequency radiation pattern is not uniform in the sense that not all
directional. Besides the antenna material used is also not easily available and the
price is not cheap. This paper will discuss the design of a Vivaldi micro strip antenna
which has a wide bandwidth with directional radiation pattern works on 3.1 to 10.7
GHz and using cheaper substrate. Substrates used for Vivaldi micro strip antenna
Vivaldi is FR4 with a dielectric constant of 4.3 and a thickness of 1.6 mm. Based
on the simulation results we obtained that the antenna design has frequency range
3.1-10.7 GHz for return loss less than -10 dB with a directional radiation pattern.
This antenna gain is 4.8 to 8 dBi with the largest dimension is 50 mm x 40 mm.

Abstract. Population distribution pattern is directly related with economic gap of a
region. Analysis of population distribution pattern is usually performed by studying
statistical data on population. This study aimed to analyze population distribution
pattern using image analysis concept, i.e. using satellite images. Level set and
morphological image filtering methods were used to analyze images to see
distribution pattern. The research result showed that Levelset and morphological
image filtering could remove a lot of noises in analysis result images and form
object edge contours very clearly. The detected object contours were used as
references to recognize population distribution pattern based on satellite image
analysis. The pattern made based on the research result didn’t show optimal result
because Level set performed image segmentation based on the contours of the
analyzed objects. Other segmentation methods should be combined with it to
produce clearer population distribution pattern.

Marauke. Kabupaten Gorontalo is one of many places in Indonesia that have
different types of minerals and natural resources that can be found in every district.
The abundant of mining potential must be balanced with good management and ease
of getting information by investors. The current issue is, (1) ways of presenting
data/information about potential mines area is still manually (the maps that already
capture from satellite image, then printed and attached to information board in the
office) it caused the difficulties of getting information; (2) the high cost of maps
printing; (3) the difficulties of regency leader (bupati) to obtain information for
strategic decision making about mining potential. The goal of this research is to
build a model of Geographical Information System that could provide data
management of potential mines, so that the investors could easily get information
according to their needs. To achieve that goal Research and Development method is
used. The result of this research, is a model of Geographical Information System

Abstract. Rainfall rate forecasting plays an important role in various human
activities. Rainfall forecasting is a challenging task due to the uncertainty of natural
phenomena. In this paper, two neural network models are proposed for monthly
rainfall rate forecasting. The performance of the proposed model is assesses based
on monthly rainfall rate in Ampel, Boyolali, from 2001-2013. The experiment
results show that the accuracy of the first model is much better than the accuracy of
the second model. Its average accuracy is just above 98%, while the accuracy of the
second model is approximately 75%. In additional, both models tend to perform
better when the fluctuation of rainfall is low.

Abstract. Disparities in regional development methods are commonly identified using the
Klassen Typology and Location Quotient. Both methods typically use the data on the gross
regional domestic product (GRDP) sectors of a particular region. The Klassen approach can
identify regional disparities by classifying the GRDP sector data into four classes, namely
Quadrants I, II, III, and IV. Each quadrant indicates a certain level of regional disparities based on the GRDP sector value of the said region. Meanwhile, the Location Quotient (LQ)
is usually used to identify potential sectors in a particular region so as to determine which
sectors are potential and which ones are not potential. LQ classifies each sector into three
classes namely, the basic sector, the non-basic sector with a competitive advantage, and the
non-basic sector which can only meet its own necessities. Both Klassen Typology and LQ are
unable to visualize the relationship of achievements in the development clearly of each region
and sector. This research aimed to develop a new approach to the identification of disparities
in regional development in the form of hierarchical clustering. The method of Hierarchical Agglomerative Clustering (HAC) was employed as the basis of the hierarchical clustering
model for identifying disparities in regional development. Modifications were made to HAC
using the Klassen Typology and LQ. Then, HAC which had been modified using the Klassen
Typology was called MHACK while HAC which had been modified using LQ was called
MACLoQ. Both algorithms can be used to identify regional disparities (MHACK) and
potential sectors (MACLoQ), respectively, in the form of hierarchical clusters. Based on the
MHACK in 31 regencies in Central Java Province, it is identified that 3 regencies (Demak,
Jepara, and Magelang City) fall into the category of developed and rapidly-growing regions, while the other 28 regencies fall into the category of developed but depressed regions. Results
of the MACLoQ implementation suggest that there is only 1 regency which falls into the
basic-sector category (Banyumas), while the other regencies fall into the non-basic non-
competitive sector category

Abstract. Generally, rendering an image based on a 3D scene requires a high
amount of computation. Thus, rendering can be a time-consuming process. Using
multiple hardware to collaboratively perform a 3D rendering is one of the most
commonly used option to reduce the time. However, the cost to access dedicated
hardware can be expensive. We present Collaborative Rendering, an application to
perform a ray-tracing-based-rendering on volunteered mobile devices. This
application allows mobile device owners to donate their processing power to
perform the rendering. Our objective is to design, implement, and evaluate
Collaborative Rendering as a solution to perform rendering process in multiple
volunteered mobile devices.

Abstract. The Government of Indonesia is currently faced with the problems of food, especially rice. It needs in large numbers that have to import from neighboring countries.
Actually, the Indonesian government has the ability to produce rice to meet national needs
but is still faced with the problem of pest attack rice annually increasing extent. One of the
factors is that geographically Indonesia located on the migration path of world rice insect pests (called BPH or Brown Plant hoppers) (Nilaparvata lugens Stal.) It leads endemic status
annually. One proposed strategy to be applied is to use an early warning system based on a
specific region of the main pest population. The proposed information system called
GEODATA. GEODATA is Geospatial Outbreak of Disease Tracking and Analysis. The system works using a library ESSA (Exponential Smoothing - Spatial Autocorrelation)
developed in previous studies in Satya Wacana Christian University. GEODATA built to
meet the qualifications required surveillance device by BMKG (Indonesian Agency of
Meteorology, Climatology and Geophysics’ Central Java Provinces), BPTPH (Indonesian Agency of Plant Protection and Horticulture) Central Java Provinces, BKP-KP District
Boyolali, Central Java, (Indonesian Agency of Food Security and Agriculture Field
Supervisor, District Boyolali, Central Java Provinces) and farmer groups. GIS GEODATA
meets the needs of surveillance devices that include: (1) mapping of the disease, (2) analysis of the dynamics of the disease, and (3) prediction of attacks / disease outbreaks in a particular
region. GIS GEODATA is currently under implementation in the laboratory field

Abstract. According to Undang-Undang Dasar Republik Indonesia 1945 Pasal 36,
Bahasa Indonesia is a National Language of Indonesia. It means Bahasa Indonesia
must be used as an official language in all levels ranging from government to
education as well as in development of science and technology. The Government
of Republic of Indonesia as the highest and formal authority must use official
Bahasa Indonesia in their activities including in their official websites. Therefore,
the government issued a regulation instruction called Instruksi Presiden (Inpres)
No. 2 Tahun 2001 to govern the usage of official computer terms in Bahasa
Indonesia. The purpose of this research is to evaluate the usage of official
computer terms in Bahasa Indonesia compared to the computer terms in English.
The data are obtained from the government official websites in Indonesia. The
method consists of data gathering, template detection, string extraction and data
analysis. The evaluation of official computer terms in Bahasa Indonesia falls into
three categories, such as good, moderate and poor. The number of websites in good
category is 281 websites, the moderate category is 512 websites and the poor
category is 290 websites. The authorized institution may use this result as
additional information to evaluate the implementation of official information
technology terms in Bahasa Indonesia.

Abstract. The coffee beans roast levels have some characteristics. However, some
people cannot recognize the coffee beans roast level. In this research, we propose to
design a method to recognize the coffee beans roast level of images digital by
processing the image and classifying with back propagation neural network. The
steps consist of how to collect the images data with image acquisition, pre-
processing, feature extraction using Gray Level Co-occurrence Matrix (GLCM)
method and finally normalization of data extraction using decimal scaling features.
The values of decimal scaling features become an input of classifying in back
propagation neural network. We use the method of back propagation to recognize
the coffee beans roast levels. The results showed that the proposed method is able
to identify the coffee roasts beans level with an accuracy of 97.5%.

Abstract. Presentation is one the most common activity performed in various fields
of work (e.g. lecturer, employee, manager, etc.). The purpose of presentation is to
demonstrate or introduce presenters’ idea to the attendees. Within the given time
and specific place, presenters have to transfer their knowledge and leave great
impression for their audience. Generally, presenters use several handy tools such as
mouse, presenter, and webcam to help them to navigate their slides. Nevertheless,
some of these tools have several constraints and limitations such as not portable and
does not support multimedia. In this research, we develop an application that assist
presenters to control their presentation materials by using Microsoft KINECT. In
this research, we manipulate colour image, image depth, and the skeleton of the
presenters captured by the KINECT. Then, we show the post-process image results
into the projector screen. The KINECT has more useful than other tools because it
supports video and audio recording. Moreover, it also able to capture presenters’
movement that can be used as an input to interact and manipulate the content (i.e.
by touching the projection wall). Not only this application provides an alternative
in controlling presentation activity, but it also makes the presentation more efficient
and attractive.

Abstract. Kamus Besar Bahasa Indonesia (KBBI), an official dictionary for
Indonesian language, provides lists of words with their meaning. The online version
can be accessed via Internet network. Another online dictionary is Kateglo. KBBI
online and Kateglo only provides an interface for human. A machine cannot retrieve
data from the dictionary easily without using advanced techniques. Whereas, lexical
of words is required in research or application development which related to natural
language processing, text mining, information retrieval or sentiment analysis. To
address this requirement, we need to build a lexical database which provides well-
defined structured information about words. A well-known lexical database is
WordNet, which provides the relation among words in English. This paper proposes
the design of a lexical database for Indonesian language based on the combination
of KBBI 4th edition, Kateglo and WordNet structure. Knowledge representation by
utilizing semantic networks depict the relation among words and provide the new
structure of lexical database for Indonesian language. The result of this design can
be used as the foundation to build the lexical database for Indonesian language.

Abstract. Activities correspondence is often used by agencies or companies, so
that institutions or companies set up a special division to handle issues related to
the letter management. Most of the distribution of letters using electronic media,
then the letter should be kept confidential in order to avoid things that are not
desirable. Techniques that can be done to meet the security aspect is by using
cryptography or by giving a digital signature. The addition of asymmetric and
symmetric algorithms, i.e.RSA and AES algorithms, on the digital signature had
been done in this study to maintain data security. The RSA algorithm was used
during the process of giving digital signature, while the AES algorithm was used
during the process of encoding a message that will be sent to the receiver. Based
on the research can be concluded that the additions of AES and RSA algorithms
on the digital signature meet four objectives of cryptography: Secrecy, Data
Integrity, Authentication and Non-repudiation. Keywords: Mail, Digital

Abstract. Dual-pivot quicksort, which was proposed by Yaroslavsky, has been
experimentally proven to be more efficient than the classical single-pivot quicksort
under the Java Virtual Machine [6]. Moreover, Kushagara, López-Ortiz, and Munro
[4] has shown that triple-pivot quicksort runs 7-8% faster than dual-pivot quicksort
in C, mutatis mutandis. In this research, we implement and experiment with single,
dual, triple, quad, and penta-pivot quicksort algorithms in Python. Our experimental
results are as follows.Firstly, the quicksort with single pivot is the slowest among
the five variants. Secondly, at least until five (penta) pivots are being used, it is
proven that the more pivots are used in a quicksort algorithm, the faster its
performance becomes. Thirdly, the increase of speed resulted by adding more pivots
tends to decrease gradually.

Abstract. This research aims to study the efficiency of two variants of variable-
length codes (i.e., Goldbach G0 codes and Even-Rodeh codes) in compressing texts.
The parameters being examined are the ratio of compression, the space savings, and
the bit rate. As a benchmark, all of the original (uncompressed) texts are assumed to
be encoded in American Standard Codes for Information Interchange (ASCII).
Several texts, including those derived from some corpora (the artificial corpus, the
Calgary corpus, the Canterbury corpus, the large corpus, and the miscellaneous
corpus) are tested in the experiment. The overall result shows that the Even-
Rodehcodes are consistently more efficient to compress texts than the
unoptimzedGoldbach G0 codes.

Abstract. The sand dunes which located in Parangtritis, is a unique eolian landform
because it’s the only type of landform that exist in Southeast Asia. This unique
characteristic makes the sand dune become a potential spot for tourism. The tourism
activity that exist inflict an impact to the sand dune’s ecological aspect. Data was
collected by using aerial photograph, interview, field observation, and literacy
study. Descriptive analysis is used for the qualitative data and spatio-temporal
analysis is used to determine the change that occur on the specific landform. Patch
Mosaic model is used to determine the change in the landscape structure. The study
shows that the tourism activity have a positive impact on the social and economic
aspect of the society around the sand dune. Raise in the society’s income and their
developing economic sector shows the positive impact of sand dune to the economic
aspect. Impact on social aspect indicated by the increase of male teenager
productivity in tourism management activity. On the other side, ecological aspect
of the sand dune receive the negative impact. The landscape matrix has decline over
time. In 2011, sand dune become the landscape matrix with an area of 46,64 Ha, but
in 2014 the landscape matrix change into agriculture field with an area of 27,82 Ha
and the area of sand dune decline to 19,81 Ha. This decline is caused by the raising
tourism activity. The area of the sand dune continue to decline in 2016 as the area
of the sand dune reach the number of 14,00 Ha and bare land become the landscape
matrix with an area of 25,78 Ha. The application of zoning regulation according to
landform processes and the implementation of geoscience maritime park tourism
concept is expected to become the base of management so that the sand dune
function can be maintain.

Abstract. This study aims to determine the quality of Jakarta Capital Region’s
groundwater and its recommendation based on the standards set by the Indonesian
government especially The Health Minister Decree No. 907 / Menkes / SK / VII /
2002 about The Drinking Water Monitoring. The study activity uses the data that
carried out by Geological Agency, Ministry of Energy and Mineral Resources,
Indonesia from March to April 2015. The methods used in this study are direct
observation and hydrogeological measurement to measure physics and chemistry
parameters. The results show that most places in the study area have the low quality
of groundwater which is below the drinking water quality standards according to the
government. However, at the unconfined aquifer (depth of 0-40 meters), the certain
areas such as in the Kramat Jati, Halim Perdana Kusuma, Tongkol-Pademangan,
and Duren sawit are still relatively safe for consumption as drinking water. In
addition, the confined aquifer (depth> 40 meters) such as in the area of Cibubur,
Pasar Rebo, and Jagakarsa are considered safe for consumption as drinking water.
This study is expected to be used as a benchmark for researchers, especially
academics in the region in order to maintain the sustainable groundwater resources in the area.

these conditions, the level of forecasting accuracy will be decrease. Hence we need
a method that capable to reducing error value in anomalous load forecasting.
Learning process of algorithm is supervised or controlled, then some parameters are
arranged before performing computation process. Momentum constanta value is set
at 0.8 which serve as a reference because it has the greatest converge tendency.
Learning rate selection is made up to 2 decimal digits. In addition, hidden layer and
input component are tested in several variation of number also. The test result leads
to the conclusion that the number of hidden layer impact on the forecasting accuracy
and test duration determined by the number of iterations when performing input data

Abstract. Cars using the principle of converting heat energy into mechanical
energy, but a lot of wasted heat energy not entirely transformed into mechanical
energy, studies have been conducted that converts the heat energy into electrical
energy using the principle thermoelectrically. However, there are many other
energies that can be harnessed from the car, such as when the car is parked in the
sun or driving in the heat of the sun, the temperature in the cabin can reach 80
degrees Celsius. The heat can be harmful to humans and the children immediately
into the vehicle, as well as for the goods stored in the cabin if it contains toxins can
evaporate because of the heat and dangerous. The danger can be prevented by
reducing the heat in the cabin and transform into other forms of energy such as
electricity. By providing a temperature difference of 40 degrees on the cold side of
the module can be acquired electricity thermoelectrically up to 0.17W for one of its
module, if it is made a module block the energy produced is enough to lower the
temperature and charge batteries for further cooling. This study will use experiment
method to get the maximum drop in temperature in the car cabin.

Abstract. This paper describes the development of a multidisc AFPM generator
type namely the double sided internal stator. This generator consists of one stator
disc with two surface sides placed in the middle between two rotor discs. 18
permanent magnet poles are placed in one rotor disc while 9 three-phase windings
with 1450 turns per-winding are placed in one surface side of the stator disc. The
laboratory test results show that three-phase sinusoidal voltage magnitude in range
of 79 – 150 V (phase to neutral) is generated for 219 – 402 rpm of rotor speed. In
its nominal speed i.e. 333 rpm, a 124.8 V, 50 Hz, three-phase sinusoidal voltage is
generated with only 1.6% THD in average and 0°,–124°,–240° phase angles.
Comparison with another type of multidisc AFPM generator namely the double
sided internal rotor shows that the developed AFPM generator can producean output
voltage that is almost 2.5 times higher. Nevertheless, both generators are able to
generate a relatively balance three-phase sinusoidal voltage with low THD value.

Abstract. Fire disasters can occur anytime and result in high losses. It is often that
fire fighters cannot access the source of fire due to the damage of building and very
high temperature, or even due to the presence of explosive materials. With such
constraints and high risk in the handling of the fire, a technological breakthrough
that can help fighting the fire is necessary. Our paper proposed the use of robots to
extinguish the fire that can be controlled from a specified distance in order to reduce
the risk. A fire extinguisher robot was assembled with the intention to extinguish
the fire by using a water pump as actuators. The robot movement was controlled
using Android smartphones via Wi-fi networks utilizing Wi-Fi module contained in
the robot. User commands were sent to the microcontroller on the robot and then
translated into robotic movement. We used ATMega8 as main microcontroller in
the robot. The robot was equipped with cameras and ultrasonic sensors. The camera
played role in giving feedback to user and in finding the source of fire. Ultrasonic
sensors were used to avoid collisions during movement. Feedback provided by
camera on the robot displayed on a screen of smartphone. In lab testing environment
the robot can move following the user command such as turn right, turn left, forward
and backward. The ultrasonic sensors worked well that the robot can be stopped at
a distance of less than 15 cm. In the fire test, the robot can perform the task properly
to extinguish the fire.

Abstract. Dengue is still one of major health problem in Indonesia. Dengue transmission is influenced
by dengue prevention and eradication program, community participation, housing environment and
climate. The complexity of the disease coupled with limited resources necessitates different approach for
prevention methods that include factors contribute to the transmission. One way to prevent the dengue
transmission is by reducing the mosquito’s breeding sites. Four factors suspected to influence breeding
sites are dengue prevention and eradication program, community participation, housing environment, and
weather condition. In order to have an effective program in reducing the breeding site it is needed to have
a model which can predict existence of the breeding sites while the four factors under study are controlled.
The objective of this study is to develop an Ecohealth model using system dynamic as a planning tool for
the reduction of breeding sites to prevent dengue transmission with regard to dengue prevention and
eradication program, community participation, housing environment, and weather condition. The
methodology is a mixed method study using sequential exploratory design. The study comprised of 3
stages: first a qualitative study to 14 respondents using in-depth interview and 6 respondents for focus
group discussion. The results from the first stage was used to develop entomology and household survey
questionnaires for second stage conducted in 2036 households across 12 sub districts in Bandung City.
Ecohealth system dynamic model was developed using data from first and second stages. Analyses used
are thematic analysis for qualitative data; spatial, generalized estimating equation (GEE) and structural
equation modeling for quantitative data; also average mean error (AME) and average variance error
(AVE) for dynamic system model validation. System dynamic model showed that the most effective
approach to eliminate breeding places was by ensuring the availability of basic sanitation for all houses.
Weather factors such as precipitation can be compensated with the eradication of breeding sites activities
which is conducted as scheduled and at the same time for the whole areas. Conclusion of this study is
that dengue prevention and eradication program, community participation, and housing environment
contributed to breeding places elimination influenced the existence of the breeding sites. The availability
of basic sanitation and breeding places eradication program done timely and collectively are the most
effective approach to eradicate breeding sites. Ecohealth dynamic system model can be used as a tool for
the planning of breeding sites eradication program to prevent disease transmissions at city level.
Keywords: System dynamic, Ecohealth, timely breeding sites eradication program, breeding sites, dengue

Abstract. Modern buildings in Indonesia rely mostly on artificial lighting, heating,
cooling and ventilation. It means more energy is used to drive mechanical
appliances, and presumably not sustainable. Meanwhile modern buildings consume
much energy, traditional architectures are known as the source of knowledge for
sustainable, energy efficient and climate responsive design. Noticeably, one of the
differences between modern and traditional buildings in Indonesia is shown in their
strategy to provide thermal comfort to the user. Traditional buildings use natural
ventilation, but modern buildings use mechanical air conditioning. By focusing on
wind-driven ventilation, the study aims to investigate natural ventilation strategy of
Indonesian traditional house, and their potential improvement to be used in modern
Indonesian buildings. Three traditional houses are studied in this research,
representing west, central, and east Indonesia. The houses are Lampung traditional
house, Javanese traditional house, and Toraja traditional house. CFD simulation is
conducted to simulate wind-driven ventilation behaviour and the temperature of the
buildings. Concisely, the wind-natural ventilation of case study houses is potential
to provide thermal comfort inside the houses. However, the strategy still can be
optimized by adding some other passive design strategies: sunshading; vegetation;
or buildings arrangement in the traditional dwelling. Consideration about the roof’s
shape and windows position to the roof is important as well to create a uniform air
distribution.

Abstract. This study aims to determine the influence of architectural design on the
risk of fires pread in densely urban settlement area. Cellular Automata (CA) is used
to analyse the fire spread pattern, speed, and the extent of damage. Four cells
represent buildings, streets, and fields characteristic in the simulated area, as well as
their flammability level and fire spread capabilities. Two fire scenarios are used to
model the spread of fire: (1) fire origin in a building with concrete and wood material
majority, and (2) fire origin in building with wood material majority. Building
shape, building distance, road width, and total area of wall openings are considered
constant, while wind is ignored. The result shows that fire spread faster in the
building area with wood majority than with concrete majority. Significant amount
of combustible building material, absence of distance between buildings, narrow
streets and limited fields are factors which influence fire spread speed and pattern
as well as extent of damage when fire occurs in the densely urban settlement area.

Abstract. A study has been conducted in an area of coffee plantation in Samosir
District, North Sumatera Province. The study was conducted in August until
September 2016. The objective of this studyis to investigate the benefits of using
biogas technology in supporting coffee farmers’ productivity to be sustainable, i.e.
methane as energy source for coffee roasting proceed instead of fired wood and
slurry as organic fertilizer. Coffee cherry causes environmental problem when it is
dumped openly, hence it is used to mix with buffalo feces in biodigesters to produce
methane and organic fertilizer.Fivebiodigesters were used with 5 differents designs
of composition: T1) 100% buffalo feces, T2) 75% buffalo feces + 25% coffee
cherry, T3) 50% buffalo feces + 50% coffee cherry, T4) 25% buffalo feces + 75%
coffee cherry, and T5)100% coffee cherry. The key parameters measured were
methane production and slurry chemical compositions including NPK, pH, and C/N.
It is found that designs T1 and T2 were superior in methane production, and about
400 liters of methane were used in roasting 3 kg coffee bean as opposed to 6,6 kg
fired wood. Designs T1 and T2 were also better in slurry chemical compositions
than the other 3 designs. It is recommeded that local coffee farmers utilize coffee
cherry based biogas technology in order for their productivity to be sustainable. It is
noteworthy that this study is continued with the next one in which the resulting
slurries are implemented to foster the growth of the coffee plants during the period
of October until December 2016.

Abstract. Peatfire in Indonesia recently had become an important issue regarding
its global warming impact of green house gases emitted. Emission factor is one of
important variables to determine total emission of carbon released by peatfire. But
currently there were only a few studies about Indonesian peat fire emission factors.
The previous studies of Indonesian peat fire emission factor reported the results from
a very limited number of samples and during smoldering combustion stages only.
Therefore this study attempts to quantify carbon dioxide (CO2) and methane (CH4)
emission factors from laboratory peat combustion based on higher number of
samples and taken both of combustion stages (flaming and smoldering) into
consideration. Peats were sampled from five different districts in Pontianak, West
Kalimantan. Ultimate analysis showed that pure peat composed of relatively high
carbon content (52.85 – 59.43% dry basis). Laboratory experiments were carried out
by burning small amout of peats in a mini furnace and measuring their CO2 and
CH4 emission concentration during flaming and smoldering. CO2, CO and CH4
average emission factors and their related average MCE for flaming were found to
be 2,088 ± 21 g/kg (n = 17), 3.104 ± 7.173 g/kg (n = 17), 0.143 ± 0.132 g/kg (n =
17) and 0.998 ± 0.005 (n = 17), respectively, while for smoldering were 1,831 ± 131
g/kg (n = 17), 138 ± 72 g/kg (n = 17), 17 ± 12 g/kg (n = 17) and 0.894 ± 0.055 g/kg
(n = 17), respectively. This emission factors based on the laboratory combustion
experiment can be conveniently used to estimate CO2 and CH4 emission from
Indonesian peat fire. Equation models to correlate between MCE and emission
factors for both flaming and smoldering were developed. MCE and CO2 emission
factor during flaming was relatively higher than smoldering. On the contrary, CO
and CH4 emission factors were relatively smaller during flaming than smoldering.

Abstract. Lots of activities in production process can be lead to waste activities.
The waste may cause a degree of efficiency of an industry to be low. This research
was conducted in the rubber industry. In the rubber industry has been a decline in
the level of efficiency. Decreased levels of efficiency occurs because many
inefficient activities that take place during the production process. Activities that
were not contributed to the value of the product lead to waste during the production
process. Identification by the activity is a way to minimize the waste that occurs
so that the efficiency of the production process can be improved. Process activity
mapping in the rubber industry used to identify the activities that take place on the
floor of production in order to reduce waste and propose improvements that can
be done to improve efficiency. The total waste that occurs in crumb rubber industry
amounted to 94 minutes or 1.56 hours.For the proposed improvements in order to
reduce waste are based on two activities, such as transport and unnecessary
motion. Transport activities proposed use of material handling in their daily
activities and to unnecessary motion bydoing a variety of work on the operator.

Abstract. This study observes sorters’ performance in two beverage industries
whose job is to separate defect products found. Sorters observe bottles quality and
beverage quality continuously, therefore requiring more focused eyes which makes
eyes’ load heavier. Sorters’ eyestrain causes more defect products pass the selection.
In this study, measurement is conducted toward ilumintation, operators’ time
response, and defect products that pass the selection. Measurement is hold in 2
beverage industries for four days with four measurements per day, twice in the
morning and twice in the afternoon. Ilumination is measured with 4 in 1
environmental meter in grid 1m x 1m, while operators’ time response is measured
with Flicker Fusion. Illuminance is generally higher in the morning than in the
evening, but still under the standard of Indonesia. Overall, sorters’ time response is
higher in the morning than in the afternoon. Higher time respone shows that
operators experiencing lower fatigue than lower time response. The sorting duration
also affects operators’ time response and defect products which pass the selection.

Abstract. Performance assessment on the supplier by the supermarket manager is
relatively difficult to conduct and implies subjectivity, because there is no
measureable and objective performance indicator. This study aims to assist in the
decision making process and to look for alternative solutions in assessing the
performance of each supplier, so that the service towards the customers will
improve as well. ANP method is used to find the weight of each sub-criteria that
will be used to measure the supplier performance. The weight result of each sub-
criteria derived from the ANP method is used again in measuring the performance
and to rank the performance of each supplier by using TOPSIS
method. Performance measuring by using the ANP and TOPSIS that generates the
highest value of the supplier is 0.71666 while the lowest value is 0.24825. The result
of this study shows that the ANP and TOPSIS methods can be used to measure the
supplier performance therefore it can assist the selection of supplier which can
increase service towards the mart’s consumers.

Email: [email protected]
Abstract. The success of an artificial insemination of cattle depends on the accuracy
of timing of semen injection within a certain duration of time during the estrus phase
of the female cattle. Contemporary practice in traditional cattle reproductive system
relies on the visual observation of estrus indicators.This paper proposes for the
design of a Decision Support System assisting the determination of semen injection
to post-partum female cattle.The system would suggest the time frame for injection
treatments, the distance of the location from the center point, and the best route of
the treatments for multiple locations based on the shortest route path algorithm. The
paper concludes with the potential contributions of such system for the development
of Precision Livestock Farming and rural farmers’s prosperity.

Abstract. Two populations of red mangrove Rhizophora mangle L.
(Rhizophoraceae) in Ecuador was examined using five microsatellite primers.
Microsatellite loci were low polymorphic with 2-5 alleles per locus. The level
observed heterozygosity detected overall loci population, ranged from 0.189 to
0.405, indicating that these populations had little or no genetic variation.
Furthermore, genetic variation was maintained within population (GST=0.012). Both
populations showed high level of inbreeding (FIS=0.695, FST=0.024), suggested that
mangrove species behave as colonizing species. The genetic structure was tested by
analysis of molecular variance (AMOVA) using the infinite alleles model (F-
statistics), found that most variation was among individuals within population (33.3
%) and within individuals in the total populations (66.6 %), whereas there was little
variation between populations (0.1 %). An understanding of genetic variation of R.
mangle suggested the importance of conservation this species to increase the
number of populations.

Abstract. Background: The mechanism of low circulating 25(OH)D serum in obese
people may be due to high 25(OH)D level in adipocyte resulting low in circulation
or low vitamin Dbinding protein (DBP). However, obese people have a higher bone
mineral density (BMD), which suggests that low 25(OH)D may not associate with
other bone health parameters. Objective:We sought to determine whether there is
association between 25(OH)D 1) with bone health parameter differ by body weight;
2) Body mass index and BMD. Design: We conducted a cross-sectional
observational study of 132 women aged 20-50 years in North Sumatera, Indonesia.
Results: Serum total 25(OH)D was no different in normal, overweight, and obese
women subjects ( 15.2±4.9 ng/mL). There was 77.3% categorized in deficiency and
insufficiency (22.7%). There was no association among bone health parameters and
body weight, but there is an association between BMD and body weight.

Abstract. Non-communicable diseases (NCDs) have become the leading causes of
death globally, including Indonesia. This study is conducted to find out the
distribution of obesity and diabetes mellitus (DM) in adult female population in
North Sumatera Utara, Indonesia. A cross-sectional study was conducted from
August to September 2016 on a total of 200 adult female respondents aged 20-65
years who agreed to participate in Langkat district and Medan city, North Sumatra.
Criteria of obesity based on Body Mass Index (BMI), might be inappropriate for
Asian population. DM was diagnosed if plasma glucose level is >200 mg/dl. The
prevalence of obesity in female among aged ≥20 years were 68.5%. Subsequently,
obesity and overweight categories of BMI are highest in the 41-50 year age group
(35.5% and 20.5% respectively) as well as pre-DM and DM (24.5 and 11.5%,
respectively). The age group of 41-50 years old have also the highest rates of obesity
and overweight BMI categories as well as highest rate of DM in this research. In
addition, more investigation is needed to establish a relationship between obesity
and DM. Therefore, comprehensive strategies for the prevention and control of the
problem of obesity and DM in adult female are urgently required.

Abstract. Plant actin is one of the most conserved eukaryotic proteins to maintain
the basic cellular process. Homology based PCRs method with degenerate primers
designed from the conserved amino acid sequences of diverse actin genes have
resulted in cloning of three actin genes. Three partial actin genes were cloned from
mangrove family Rhizophoraceae, namely leaves of Bruguiera gymnorrhiza, roots
of Kandelia candel and leaves of Rhizophora stylosa. The clones termed BgAct1
(944 bp, coding for 273 amino acids), KcAct1 (1083 bp, coding for 273 amino acids),
and RsAct1 (894 bp, coding for 273 amino acids), respectively. The deduced amino
acid sequences of BgAct, KcAct1 and RsAct1 showed significant similarity (93-96%)
to known plant actin genes. These results showed that three fragment genes of
BgAct, KcAct1 and RsAct1 encoded actin gene. To observe the relationship of BgAct,
KcAct1 and RsAct1 to other plant actin genes, the rooted phylogenetic analysis was
constructed. Phylogenetic tree shows that BgAct, KcAct1 and RsAct1 join with
Eucommia Act and Pyrus Act cluster, suggesting that our three actin genes are new
members of plant actin genes.

Abstract. The objective of this study is to determine the activity of Theta brainwave
as the response to Lavender aromatherapy inhalation of postgraduate students with
academic stress condition. This research involved 10 postgraduate students
consisted of 5 males and 5 females who were still pursuing their final research and
were recruited based on assigned criteria and filled two modified questionnaires to
determine the stress category. The procedure of Lavender aromatherapy inhalation
was given intentionally for a period of 16 days of experiments for 15 minutes of
each day. Evaluation of brain electrical activity focused on Theta (frequency 4-7Hz)
and were recorded by Electroencephalograph (EEG) EMOTIV EPOC from 6
channel electrodes on the scalp (AF3, AF4, T7, T8, P7, P8). Essential oil compound
from Lavender was evaluated by using GCMS (Gas Chromatography Mass
Spectrometry). Data were analysed by comparing baselines before treatment and
two weeks after aromatherapy administration using General Linear Model and
Paired t-test statistical procedure. The result revealed that: (1) the main constituents
of Lavender essential oil are linalool (20,11%) and linalyl acetate (26,34%), (2)
there was no significantly increase in Theta power both in women and men (p >
0,05), (3) there was an asymmetry of Theta brainwave pattern at P7 and P8 channel
in women. The constituents of Lavender essential oil activate olfactory neuron and
modulate inhibitory neurotransmitter toinfluence EEG pattern.

Abstract. Toll-like receptors (TLRs) are a family of innate immune receptors that
recognize molecular patterns associated with microbial pathogens (PAMP), and
induce antimicrobial immune responses. Here we report expression of TLR2
/myd88/IL1β from the Gouramy an economically freshwater fish in Indonesia.
Upon stimulation with Aeromonas hydrophila the Osp TLR2 expression was
obviously upregulated in spleen and liver, Myd88 expression upregulataed in spleen
and kidney, and IL1β expression was upregulated in spleen, kidney and liver.
Highest expression of TLR2 was in liver orhepatopancreas, MyD88 in kidney and
IL1β was in spleen. Inductive expression of TLR2, MyD88, IL1β genes were
observed following LPS/Poli IC/Zymosan –treatment in kidney cell, and
Aeromonas hydrophila infections. These findings together highlighted the
contribution of TLR2 in augmenting innate immunity in fish, and indicated t’s
important role in immune surveillance of various organs during pathogenic
invasion. This study will enrich the information in understanding the innate immune
mechanism in fish, and will be helpful in developing preventive measures against
infectious diseases in fish.

The Prediction of Sensitivity towards Uncanniness: an
Applied Psychological Study on Novel Readers in the
light of Anthropomorphism and Attitudes towards
Thrownness

E-mail: [email protected]
Abstract. Uncanny elements are often found in the art works, especially in fiction
literature. In particular, uncanniness emphasizes the sense of strangeness or
weirdness that comes from something seemingly familiar within an unexpected
context; e.g. talking animals contained in a story. People have different levels of
sensitivity to the sense. Novels with the fantasy genre have been linked with
uncanniness. The preference toward the uncanniness might be associated with
magical thinking. Anthropomorphism, the attribution of human character in objects
or animals, as a dimension of the thinking, is hypothesized to be able to predict
sensitivity to uncanniness. The attitude toward thrownness could also allegedly
predict the sensitivity. A positive attitude might function as an escape from, or the
compensatory fulfillment of, existential emptiness. Participants of this study were
162 university students (67 males, 95 females, Mage = 20.80 years old; SDage = 1.733
years) of the study program School of Design and Literature at Bina Nusantara
University, Jakarta, Indonesia and the University of Indonesia, Depok, Indonesia,
who were recruited through purposive sampling technique. The design of this study
was correlational-predictive, and the data were obtained through the survey using
psychological scales. Multiple linear regression analysis found that
anthropomorphism has predictive power in the positive direction, while the attitude
toward thrownness is not able to predict the sensitivity to uncanniness. This study
has implication for art psychology and life science, about how to increase the
enjoyment of readership regarding the factor raising appreciation toward a strange
or fear perception experienced by a reader.

Abstract. NiTi alloys is one of the unique materials exhibiting shape memory
effect. The martensitic transformation is the main reason for their behaviour, which
is very sensitive to the heat treatment and the ratio of Ni-Ti atoms. The study of the
NiTi alloys behaviour at the atomic level is indispensable to elucidate the
mechanism of the martensitic transformation under the specific conditions.
Molecular dynamics simulation is widely used in this kind of study. The results of
the molecular dynamics simulation depend on the selection of the interatomic
potential. This study is aimed to evaluate the performances of the standard EAM
potentials of Zhou et al. and the modified EAM of Ko et al. by means of obtaining
the more accurate lattice constant in comparison with the experimental value. These
interatomic potentials are also tested to reproduce the recrystallization behaviour
below the melting temperature. We found thatthe high accuracy of the lattice
constant for NiTi alloy systemcan be achieved by employingMEAM potential of
Ko et el.However, the EAM potential by Zhou et al. gives the rapid recrystallization
of NiTi alloys at 1100 K. These results indicatethat the MEAM potential of Ko et.
al. shows the better performance at low temperature simulation.

Abstract. Indonesia is a country with very beautiful nature at its regions. One of
the wellknown tourism resorts in North Sumatera is Brastagi tourism site. This
tourism object attracts domestic and international tourists to visit. This situation
will certainly be beneficial for people around. We can find many micro, small, and
medium enterprises (SMEs) around Brastagi site. Even though we can still find
many of SMEs, we feel dissatisfied with their financial condition. This research
aims at finding factors that cause financial satisfaction among SMEs in Brastagi
city viewed from the demography side. The demography indicators we introduce
are education, gender, age, income, marital status, number of children, business
ownership, and length of business operation. By using cross-tab method analysis,
we found out that demography factors that have correlation with financial
satisfaction of SMEs in Brastagi site are factors of education, income, business
ownership, and length of business operation. Therefore, this research concludes
that to raise the financial satisfaction, someone should consider the four
demography factors above. It is expected that the implication of this research will
improve the financial satisfaction of SMEs forentrepreneurship.

Self-Giving as Spiritual Dimension in Leadership
Arcadius Benawa1, Nuah Tarigan2, Sukron Makmun3 1,2,3Bina Nusantara University, Jakarta, Indonesia
E-mail: [email protected], [email protected],
Abstract. This article aims to show that today it is very important to consider the
spiritual dimension in leadership, because the absence of the spiritual dimension
makes it impossible for a human to evolve. As the leader, whoever should be
accountable is not only on the horizontal level and at the vertical level as well.
Phenomenological studies and literature about the practice of leadership are faced
with a number of theories about leadership and then synthesized into more whole
leadership rather than just to brand a leadership itself. Based on the assumption a
leader is merely a sociological problem that needs to be completed with a spiritual
dimension, while in its historical development of leadership, it is never excluded
from the spiritual dimension. This article concludes that self-giving as a spiritual
dimension in leadership will give more benefit to develop the life system as well as
the purpose of leadership itself rather than the apparent leadership, which actually
hurts or even manipulate the members for the sake of egoistic the leader and their
inner circle. Therefore, it is very important for education to teach self-giving as a
spiritual dimension to all students of the World, especially in Asia.

Abstract. Alpha cellulose which was isolated from cellulose of fiber empty fruit
bunch palm oil was hidrolized with hydrochloric acid (2,5N) at 80oC to produce
microcrystalline cellulose (MCC). Microcrystalline cellulose is an important
additional ingredient in the pharmaceutical, food, cosmetics, and structural
composites. In this study, MCC, alpha cellulose, and cellulose were characterized
and thereafter were compared. Characterizations were made using some equipment
such as x-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning
electron microscopy (SEM) and thermogravimetry analyzer (TGA). X-ray
diffraction and infrared spectroscopy were studied to determine crystallinity and
molecular structure of MCC, where scanning electron microscopy images were
conducted for information about morfology of MCC. Meanwhile, thermal resistance
of MCC was determined using thermogravimetry analyzer (TGA). From XRD and
FTIR, the obtained results showed that the crystalline part was traced on MCC,
where the –OH and C-O groups tended to reduced as alpha cellulose has changed to
MCC. From SEM the image showed the reduction of particle size of MCC, while
the thermal resistance of MCC was found lower as compared with cellulose and
alpha cellulose as well, which was attributed to the lower molecular weight of MCC.

Abstract. The tunneling current of n-p-n bipolar junction transistor AGNR-based is
modeled with semi-numerical method. The exponential solution from Schrödinger
equation is used and solved analytically. The potential profile of n-p-n BJT divided
into several segments in the numerical method. Then, the solved analytical result is
used in the numerical method to compute the electron transmittance. Transfer Matrix
Method (TMM) is the numerical method used to compute the electron transmittance.
From the calculated transmittance the tunneling current can be computed by using
Landauer formula with aid of Gauss-Legendre Quadrature (GLQ). Next, the
tunneling current is computed with several change of variables which are base-
emitter voltage (VBE), base-collector voltage (VBC), temperature and the AGNR’s
width. The computed tunneling current shows that the larger value of applied
voltage for both VBE and VBC results in larger value of tunneling current. At the
lower temperature, the current is larger. The computed tunneling current shows that
at wider width of AGNR, the current is also larger. This is due to the decreased band-gap energy (Eg) because of the wider width of AGNR.

Abstract. The objective of this research is to study the influence of organic fibers
on the mechanical properties and microstructure characters of hybrid composite
geopolymers-pineapple fibers (PFL). Geopolymers were synthesized by using alkali
activated of class C-fly ash added manually with short pineapple fiber leaves (PFL)
and then cured at 60ºC for 1 hour. The resulting composites were stored in open air
for 28 days prior to mechanical and microstructure characterizations. The samples
were subjected to compressive and flexural strength measurements, heat resistance
as well as acid attack (1M H2SO4 solution). The microstructure of the composites
were examined by using Scanning Electron Microscopy-Energy Dispersive
Spectroscopy (SEM-EDS). The measurement showed that the addition of pineapple
fibers was able to improve the compressive and flexural strength of geopolymers.
The resulting hybrid composites were able to resist fire to a maximum temperature
of 1500ºC. SEM examination showed the presence of good bond between
geopolymer matrix and pineapple fibers. It was also found that there were no
chemical constituents of geopolymers leached out during acid liquid treatment. It is
concluded that hybrid composite geopolymers-pineapple fibers are potential
composites for wide range applications.

Abstract. Compression by closes system compression (CSC) improved quality of
the soft-inner part of oil palm trunk (S-OPT). The problem of compressed-wood
was spring back or recovery of set, if it was exposed to moisture content. The
objective of these study were to evaluate the recovery of set (RS) and weight loss
(WL) of S-OPT by CSC. These methods were compared with heat treatment (HT)
and steam treatment (ST). Density of S-OPT was 0.3 g/cm3. All samples were
compressed to compression ratio of 50%. The compression of HT method used the
temperatur of 120, 140, 160, 180 and 200 °C for 0, 10, 30, 60 and 180 minutes; and
ST method used temperature of 120, 140, 160, 170 and 180 °C for 0, 5, 10 and 30
minute; while CSC method used temperature of 120, 140, 160, 180 and 200 °C for
0, 10, 20, 30 and 40 minutes. The results showed that the temperature and
compression time contributed to the RS and WL value for all methods. Increasing
compression temperature and time leads to decreased the RS value and to increased
the WL value. The lower RS value indicated that S-OPT fixation would be better or
high dimensional stability. Fixation of S-OPT by ST method was achieved at
temperature of 170 °C for 30 min, CSC at temperature of 180 °C for 30 min, while
HT method has not fixated until 200 °C for 180 min.

Abstract. In the market, parquet was made from high density wood such as teak,
merbau, kempas, ulin, oak, lime, maple, or other high density wood. Parquet has
been used for flooring in specific buildings, for instance sport hall, library,
commercial building (i.e hotel lobby, hypermarket), and office building. Because of
the scarcity of high density wood nowadays and in order to find out the alternative
material for wood flooring, the utilization of sugar palm trunk was considered. In
this contribution, unproductive sugar palm tree was cut down and divided into three
sections using chain saw, namely bottom, middle, and tip. For each section, physical
and mechanical samples testing were made according to British Standard 373:1957
for small clear specimen. Investigation of both properties was done in ambient
temperature with at least three replications. Instron UTM (Universal Testing
Machine) was used to evaluate the mechanical properties. Results of the physical
testing (density, moisture content and tangential shrinkage) showed the entire trunk
was suitable for raw material of parquet. However, the results of mechanical testing
(hardness, MOE/modulus of elasticity, MOR/modulus of rupture, and compression
perpendicular to grain) showed only bottom and middle parts were suitable for raw
material of parquet while the upper part was vice versa. Keywords: parquet (wood
flooring), physical and mechanical properties, sugar palm trunk.

Abstract. The acetone sensors based on chitosan have been successfully fabricated
using an electrochemical deposition method. The physical and electrical
characterizations of chitosan film were carried out to observe the performance of the
sensor. The results showed that the chitosan based acetone sensors exhibited fast
response, complete recovery and good stability. However, the improvement of
chitosan films is still necessary due to the poor surface, low repeatability and
reproducibility. Therefore, the objective of this study is to modify chitosan film
performance by adding CMC into chitosan solution with the variation of 0.01, 0.05,
0.1 and 0.5 g. The characterization of chitosan and chitosan-CMC films were
investigated using PSA, optic microscope, DTA and FTIR. While the electrical
properties were observed by exposing the sensors to acetone gas for various
concentrations. The results showed that acetone sensor based on chitosan-0.05 w/v
CMC has the best physical and electrical properties such as homogenous surface,
high thermal property, fast response, complete recovery, good repeatability and
excellent reproducibility. Thus, the addition of CMC can improve the performance
of chitosan based acetone sensors.

Abstract. Several algorithms and objective functions on paddy crops have been
studied to get optimal paddy crops in Central Java based on the data given from
Surakarta and Boyolali. The algorithms are linear solver, least square and Ant
Colony Algorithms (ACO) to develop optimization procedures on paddy crops
modelled with Modified GSTAR (Generalized Space-Time Autoregressive) and
nonlinear models where the nonlinear models are quadratic and power functions.
The studied data contain paddy crops from Surakarta and Boyolali determining the
best period of planting in the year 1992-2012 for Surakarta where 3 periods for
planting are known and the optimal amount of paddy crops in Boyolali in the year
2008-2013. Having these analyses may guide the local agriculture government to
give a decision on rice sustainability in its region. The best period for planting in
Surakarta is observed, i.e. the best period is in September-December based on the
data 1992-2012 by considering the planting area, the cropping area, and the paddy
crops are the most important factors to be taken into account. As a result, we can
refer the paddy crops in this best period (about 60.4 thousand tons per year) as the
optimal results in 1992-2012 where the used objective function is quadratic.
According to the research, the optimal paddy crops in Boyolali about 280 thousand
tons per year where the studied factors are the amount of rainfalls, the harvested area
and the paddy crops in 2008-2013. In this case, linear and power functions are
studied to be the objective functions. Compared to all studied algorithms, the linear
solver is still recommended to be an optimization tool for a local agriculture
government to predict paddy crops in future.

E-mail: [email protected], [email protected]
Abstract: Tyre vibration represents the main source to generate the noise for light
vehicles. The physical aspects which are involved in studying tyre noise are tyre
vibrations and structure borne sound. In this paper, radial tyre displacements have
been investigated for tyre vibration characterization in natural frequency. A
cylindrical shell model has been used to analyse flexural wave’s propagation. Two
important features of flexural wave propagation on a cylindrical shell were analysed,
lower order modes of the second and third radial mode sets are in the range where
the membrane effects in sidewall are relatively large. The tread band and sidewall
responses of the tyre have been simulated and compared. As a result, the
concentration of displacements has been observed in the vicinity of tyre structure.
For the simulation purposes, frequency analysis has been performed, showing the
influence of the rotating speed on the vibrations level and natural frequency content.
The study gives a physical insight on generation mechanism of tyre radial vibrations.

Abstract. In this work, a compression ignition (CI) engine is tested in dual-fuel
mode (Diesel-Raw biogas). The objective is to examine the performance and
emission characteristics of the engine when some of the diesel oil is replaced by
biogas. The specifications of the CI engine are air cooled single horizontal cylinder,
four strokes, and maximum output power of 4.86 kW. It is coupled with a
synchronous three phase generator. The load, engine revolution, and biogas flow
rate are varied from 600 W to 1500 W, 1000 rpm to 1500 rpm, 0 to 6 L/minute,
respectively. The electric power, specific fuel consumption, thermal efficiency, gas
emission, and diesel replacementratio are analyzed. The results show that there is
no significant difference of the powerresulted by CI run on dual-fuel mode in
comparison with pure diesel mode. However, the specific fuel consumption and
efficiency decrease significantly as biogas flow rate increases. On the other hand,
emission of the engine on dual-fuel mode is better. The main conclusion can be
drawn is that CI engine without significant modification can be operated perfectly in dual-fuel mode and diesel oil consumption can be decreasedup to 87.5%.

E-mail: [email protected] Abstract. Pyrolysis is the decomposition process of solid biomass into gas, tar and
charcoal through thermochemical methods. The composition of biomass consists of
cellulose hemi cellulose and lignin, which each will decompose at different
temperatures. Currently pyrolysis has again become an important topic to be
discussed. Many researchers make and install the pyrolysis reactor to convert
biomass waste into clean energy hardware that can be used to help supply energy
that has a crisis. Additionally the clean energy derived from biomass waste is a
renewable energy, in addition to abundant source also reduce exhaust emissions of
fossil energy that causes global warming. Pyrolysis is a method that has long been
known by humans, but until now little is known about the phenomenon of the
pyrolysis process that occurs in the reactor. One of the Pyrolysis’s phenomena is the
heat transfer process from the temperature of the heat source in the reactor and heat
the solid waste of biomass. The solid waste of biomass question in this research is
rubber wood obtained from one of the company's home furnishings. Therefore, this
study aimed to describe the process of heat transfer in the reactor during the process.
ANSYS software was prepared to make the simulation of heat transfer phenomena
at the pyrolysis reactor. That's the numerical calculation carried out for 1200
seconds. Comparison of temperature performed at T1, T2 and T3 to ensure that
thermal conductivity is calculated by numerical accordance with experimental data.
The distribution of temperature in the reactor chamber specifies the picture that

Abstract. Melting and solidification process of Phase Change Materials (PCMs)
are investigated experimentally. The tested PCMs are Paraffin wax and Steric acid
which typically used for solar water heater. The objective is to explore the
characteristics of the PCM when it is being melted and solidified. The experiments
are performed in a glass box. One side of the box wall is heated while the opposite
wall is kept constant and other walls are insulated. Temperature of the heated wall
are kept constant at 80oC, 85oC, and 90oC, respectively. Every experiment is carried
out for 600 minutes. Temperatures are recorded and the melting and solidification
processes are pictured by using camera. The results show that the melting process
starts from the upper part of the thermal storage. In the solidification process, it
starts from the lower part of the thermal storage. As a thermal energy storage,
Paraffin wax is better than Steric acid. This is because Paraffin wax can store more
energy. At heat source temperature of 90oC, thermal energy stored by Paraffin wax
and Stearic acid is 61.84 kJ and 57.39 kJ, respectively. Thus it is better to used
Paraffin wax in the solar water heater as thermal energy storage.

Abstract. In order to recover the waste heat from the exhaust gas of a combustion
engine, an adsorption refrigeration cycle is proposed. This is a preliminary study on
design and testing of a prototype of absorption refrigeration cycle powered by an
internal combustion engine. The heat source of the cycle is a compression ignition
engine which generates 122.36 W of heat in generator of the cycle. The pairs of
absorbent and refrigerant are water and ammonia. Here the generator is made of a
shell and tube heat exchanger with number of tube and its length are 20 and 0.69 m,
respectively. In the experiments the exhaust gas, with a mass flow rate of 0.00016
kg/s, enters the generator at 110oC and leaves it at 72oC. Here, the solution is heated
from 30oC to 90oC. In the evaporator, the lowest temperature can be reached is
17.9oC and COP of the system is 0.45. The main conclusion can be drawn here is
that the proposed system can be used to recycle the waste heat and produced cooling.
However, the COP is still low.

Abstract. Irrigation operations take a large amount of water and energy which
impact to total costs of crop production. Development of an efficient irrigation
supplying precise amount of water and conserving the use of energy can have
benefits not only by reducing the operating costs but also by enhancing the farmland
productivity. This article presents an irrigation method that promotes sustainable use
of water and energy appropriate for a developing tropical country. It proposes a drip
irrigation system supported by a combined solar-wind electric power generation
system for efficient use of water in dragon fruit cultivation. The electric power
generated is used to drive a water pump filling a storage tank for irrigating a 3000
m2 dragon fruit yield in Nguntoronadi, Wonogiri, Indonesia. In designing the
irrigation system, the plant’s water requirement was identified based on the value of
reference evapotranspiration of the area. A cost/benefit analysis was performed to
evaluate the economic feasibility of the proposed scheme. The installation of this
solar and wind drip irrigation helps provide sufficient quantity of water to each plant
using renewable energy sources which reduce dependence on fossil fuel.

Abstract. A tunneling field-effect transistor (TFET) based armchair
graphenenanoribbons (AGNRs) with variation of uniaxial strain has been modeled.
Bandgap of strained AGNR estimated by an extended tight binding method is
applied to obtain electrical characteristics of a TFET under the quantum capacitance
limit device approximation. Furthermore, the electron transmittance is calculated by
utilizing the WKB (Wentzel–Kramers–Brillouin) approach. The obtained
transmittance is then used to calculate the drain current by employing the Landauer
formula. The results show that strain parameter has significant effect on the current.
In other words, the electrical characteristics of AGNR TFET can be tuned by the
strain of AGNR.

benzoin and its suitable growing medium and 2) to get information on adventitious
root formation in Sumatran benzoin cuttings. Cutting materials (Toba benzoin and
Durame benzoin) were originated from 1 year old seedling propagated by seed.
Media used were combination of sand : rice husk (1:0 v/v; 1/1 v/v). Results showed
that interaction between media and benzoin species significantly affected primer and
secondary root lenght. While planting medium significantly improved secondary
root length and number. Benzoin species significantly affected primary
andsecondary root lenght, and secondary root number.

Abstract. Food availability affect the orangutan activities, including activities to
make nests. This study was conducted to determine the correlation between the
phenology of trees with the number of nests made by orangutans in primary forest
Resort Sei Betung, Gunung Leuser National Park. Multi linear regression was used
in this study to determine the relation and correlation between phenology and the
presence of orangutan nests on a track that has been created. It took over 6 months
(March - August 2015). There were 15 orangutan nests found on the track during
the study. The equation model was : = 27,649 -0,011X1-0,104X2-0,056X3 , and
there was no significant differences (sig >0,05). The value of R2 was 70,3%. It
means that all predictors simultaneously explain 70,3% of the presence of
orangutan’s nest, and there is an expected predictors that may be the most affect on
nest presence. The season or the intensity of rain may consider as an expected
predictor.

Abstract. The formations type of solar radio bursts can be known base on the
frequency range that is detected. The CALLISTO system works with a wide band
of the frequency making it possible to detect several types of solar burst. Indonesia
exactly at Sumedang, CALLISTO system detected the formation of solar radio
bursts forms of type II for the first time on 5 November 2014. On the other side,
CALLISTO spectrometer detects and traces the phenomenon of CME (Coronal
Mass Ejections) which causes the solar radio burst type II occurrence. In this paper
will be calculated frequency drift rate during the occurrence of solar radio bursts of
type II phenomenon on 4th November 2015 at 03:30 UT. The results of these
calculations will be discussed as a related study of drift rate during the phenomenon
of burst type II radio bursts associated with CME. The obtained drift rate during the
solar radio bursts events above 2.8 MHz / s with low drift rate so that the speed of
the CME that occurred only about 790 km / s as shown from LASCO.

Abstract. Space Science Center of Indonesian Institute of Aeronautics and Space
called LAPAN has installed several solar radio receivers named CALLISTO in
various parts of Indonesia. The equipment has made some solar radio observational
data which is indicate solar radio burst since its operation. All of the observational
data stored in the file format of Flexible Image Transport System (FITS) which is
the raw data. Therefore, it is required a such kind of related data processing to
produce a data that can be used for further research. In this paper will discuss how
the observational data of CALLISTO could be generated included the information
of data format, CALLISTO data processing techniques used in these activities as
well as some of the data processing based on data indicating solar radio bursts. As
the results, a map of solar radio spectrum as spectrograph profiles and some
determinations of frequency drift base on the data will also be discussed in this
paper.

Abstract. The endurance of upper-body muscles is one of the most important
physical fitness components. As technology develops, the process of test and
assessment is now getting digital; for instance, there are a sensor stuck to the shoe
(Foot Pod, Polar, and Sunto), Global Positioning System (GPS) and Differential
Global Positioning System (DGPS), radar, photo finish, kinematic analysis, and
photocells. Those devices aim to analyze the performances and fitness of athletes
particularly the endurance of arm, chest, and shoulder muscles. In relation to that,
this study attempt to create a software and a hardware for pull-ups through
phototransistor with ultrasonic motion sensor. Components needed to develop this
device consist of microcontroller MCS-51, photo transistor, light emitting diode,
buzzer, ultrasonic sensor, and infrared sensor. The infrared sensor is put under the
buffer while the ultrasonic sensor is stuck on the upper pole. The components are
integrated with an LED or a laptop made using Visual Basic 12 software. The results
show that pull-ups test using digital device (mean; 9.4 rep) is lower than using
manual calculation (mean; 11.3 rep). This is due to the fact that digital test requires
the test-takers to do pull-ups perfectly.
