1. INTRODUCTION

1.1 BACKGROUND

The term of internet is actually an acronym standfor interconnected networks computers means

computer network which are connected each other (Supriyanto, 2009). The internet is a network of computers that could be categorized as a WAN, connecting millions of computer surround the

world, without borders, in which every person who has a computer can join the network by simply

connection to the internet service provider (internet service provider / ISP).

To connect the PC to the internet requires network devices such as Network Interface

Card (NIC), Router, Bridge, Switch, Hub, Repeater, and Server. And a connector cable between

devices are needed. There are several types of cables one, is cable or UTP Unshielded Twisted

Pair. UTP cable is a form of a two-conductor cable bundled with the aim to reduce or eliminateelectromagnetic interference. This cable has two kinds of wiring that is Crossover Type

and Straight Type. And each cable has its own color rule sequence for each pin in the connector.

Researchers therefore initiated to reduce the kinds of neighbor combination of UTP cabling.

1.2 PROBLEM STATEMENT

1. How to use another combination of UTP cable?

2. How about the relationship between the combination of another UTP cable with the transfer

rate?

1.3 PURPOSE

1. To get a new combination of the various of UTP cabling installation

2. To know which combination has more advantages in transferring data

1.4 TH EORETICAL FUNDAMENTAL

1.4.1 UTP CABLE

There are two kinds of TP cable:

1. For cable telephone cable that contains 4 pieces (STP)

2. For computer network cable containing 8 pieces (UTP)

UTP (Unshielded Twisted Pair) serves as a medium for networking with impedance of

100 ohms (Enterprise, 2008). Called unshielded because less resistant to electromagnetic

interference. It is called twisted pair because in it there pair cables are arranged or mutually

spiral.

Cable UTP or Unshielded Twisted Pair Cable or Ethernet or usually called the LAN

cable is a cable used to connect inter-related equipment computer network (computers, hub,

switch, router). The meaning of the UTP cable is only the cord, while the head of the cord is

8 position modular connectors (8P8C) is commonly called an RJ-45 (RJ = register jack).

Cable Unshielded Twisted Pair (UTP) consists of four pairs of strings medium. Each pair is

separated by protective layer. This type of cable is solely rely on conselations effects produced

by pairs of strings, for to limit signal degradation caused by Electromagnetic Interference

(EMI) and Radio Frequency Interference (RFI). The colors of UTP cable consistof white green, green, white orange, blue, orange, white brown, brown.

1.4.2 CONNECTOR

Connector otherwise is known as the Registered Jack. Connectors used for computer

networks is an RJ-45. RJ-45 connector is eight pin connector that are used to connect the UTP

cable with socket NIC/Ethernet. From eight pin, there are only four pin that has a function. That

is pin number 1, 2, 3 and 6. Pin number 1 serves to transmit +, pin number 2 serves to transmit -

, pin number 3 serves to receives +, and pin number 6 receives-. Four pins other unused.

1.4.3 CABLE INSTALLATION METHODS

There are two types in the installation. They are Straight and Crossover type. Fitting a

Straight type just enough to equate the cable colors in one side and other side, for

example, between computer with a hub or switch. On the Straight method has the following

rules of composition of colors white orange, orange, white green, blue, white blue, green, white brown, brown.

Crossover method used to connect two devices at the same NIC to NIC, router to router

and hub to hub. On the Crossover method has the following rules of composition of colors

white orange, orange, white green, blue, white blue, green, white brown, and brown for the first

side. And for the other side the composition of colors are white green, white orange, orange,

blue, white blue, orange, white brown, brown.

1.4.4 TRANSFER RATE

Data transfer rate is the number of bits of data that passes through one medium in one

second. Generally written in bits per second (bits per second) and symbolized bit/s or bps.

Data transfer rate refers to the achieved average net bit rate that is delivered to the

application layer, exclusive of all protocol overhead, data packets retransmissions, etc. For

example, in the case of file transfer, the data transfer rate corresponds to the achieved file

transfer rate. The file transfer rate in bit/s can be calculated as the file size (in bytes), divided by

the file transfer time (in seconds), and multiplied by eight.

As an example, the data transfer rate of a V.92 voiceband modem is affected by the modem

physical layer and data link layer protocols. It is sometimes higher than the physical layer data

rate due to V.44 data compression, and sometimes lower due to bit-errors and automatic repeat

request retransmissions.

2.1 TOOLS AND MATERIALS

1.

Cable UTP

2. Connector RJ-45

3. Modem

4. Crimping tools

5. Personal computer (PC) /notebook

2.2 HOW TO MAKE A VARIOUS CABLE

1. First, prepare all equipment, especially cables, RJ-45 connectors and crimping tool.

2. Second, cut the cable of the desired and peel the first layer of cable.

3. Third, arrange the cable color and tidy up the end of cable.

4. Then, Plug the cable into the connector and make sure the end of cable right at pin

connector RJ-45.

5.

Last, make sure the position of cable in the connector and plug in the connector and cableinto crimpt tool. Firmly press until the cable is connected to the connector.

2.3 HOW TO TEST THE TRANSFER RATE

1. Connecting the modem to the computer using a cable that has been made

2. Windows + R, then type ping www.google.com ±t

2.4 HOW TO CALCULATING THE RATE TRANSFER OF UTP CABLING

To calculate the transfer rate of cable is used the formula :

From the data above, it is known that the cable 1 has an average of transfer rate 0.516 Kbps,

cable 2 has an average of transfer rate 0.574 Kbps, cable 3 has an average of transfer rate 0.564 Kbps,

cable 4 has an average of transfer rate 0.574 Kbps, and cable 5 has an average of transfer rate 0.509

Kbps. For cables 6 cannot connect, because the pins are used only pins number 4, 5, 7, 8 which are in

the theory of the pin, it is not used.

3. RESULT

a. From the research above it is known that UTP cabling techniques on RJ-45 connector that do

not follow the standard from Microsoft was no problem on internet transfer. Because the data

transfer occurs only in pin numbers 1, 2, 3 and 6. So if the cable color change do not give a

specific impact.

b. From the research above it can be seen that no effect on the transfer rate internet. The rate of

which use 8 pin cables compared with using only 4 pins has the same result.

4. CONCLUSION

UTP cabling or LAN cable has a standard rules set by Microsoft. And the rule requires us to

memorize the color sequence. And based on the research above, proving that the composition rules are

not give an effect. And the color composition does not affect the transfer speed of the internet.
