INTRODUCTION & LITERATURE REVIEW

• Majalengka Regency is considered by the West Java Provincial Government as

one of the prioritiesfordevelopment infrastructure to support the acceleration

of development including the West Java International Airport mega project

that has been built in Kertajati sub-district, as well as centers for relocation of

various industries and the concept of developing Kertajati Aero City, housing,

universities, hospitals, shopping centers, bussinescenter, resort, entertainment

and recreation (Kurniawati, 2017).

• Development carried out continuously and uncontrolled will cause the condition

of the surface temperature of land in urban areas is higher than the

surrounding area, the difference in surface temperature is called Urban Heat

Island (UHI) (Khomarudin, 2004).

METHODS

Study Area

• This research area is Majalengka regency

• The area of Majalengka Regency is 1.315 km2• astronomically located at 108° 03’-108° 25’ East

Longitude dan 6° 36’- 7° 03’ South Latitude• administrative includes 26 districts, 13 sub-

districts, and 334 villages

Data

• Land surface temperature in this study is

temperature data obtained from satellite image

processing Landsat 8 (from the United States

Geological Survey (USGS) ) path 121 row 65 in

band 10 using mono window algorithm.

• Land cover is obtained from the results of

satellite image processing using the method

supervised classification.

• Greenness vegetation is obtained from

processing the NDVI algorithm from band 5

(NIR) and band 4 (RED) on Landsat 8 imagery.

• Building density is obtained from processing the

NDBI band 5 (NIR) and band 6 (SWIR)

algorithms on Landsat 8 imagery. 4

Conclusion

Spatially-temporally, the urban heat island phenomenon in Majalengka Regency from 2013,

2016 and 2019, occurred at temperatures >30 °C which were dominated by built and open

land, with medium building density and low green vegetation. With high temperature

concentrations located in the city center in the central part and towards the north of Majalengka

Regency. Meanwhile, further away from the city, namely to the southern part of the land surface

temperature is getting lower with vegetation land cover, high green vegetation, and low building

density.

the higher the greenness of the vegetation, the lower the temperature of the land surface.

Whereas the building density shows a directly proportional relationship, meaning that the higher

the building density, the higher the land surface temperature and vice versa. Land cover is

related to land surface temperature because generally high temperatures are associated with

built-up land and low land surface temperatures are associated with vegetation land cover.
