IMPACT OF LAND COVER CHANGES ON LAND SURFACE TEMPERATURE IN DEPOK CITY

Depok City is an area that is experiencing changes in land cover due to very rapid regional development Apart from that, changes in land cover are also caused by population growth which continues to increase. This puts pressure on changes in land cover and its implications for land cover. Changes in land cover from vegetated land to built-up land will cause environmental problems, namely changes in land surface temperature. This research aims to identify land cover conditions based on the Normalized Difference Vegetation Index (NDVI), identify changes in land surface temperature, and analyze the effect of land cover changes based on NDVI on land surface temperature in Depok City in 2012-2022. This research uses spatial analysis to determine land cover changes based on the Normalized Difference Vegetation Index (NDVI) in Depok City 2012-2022. Satellite image data is interpreted to produce NDVI maps for 2 different years at a scale of 1:50,000. With changes in vegetated land cover, it causes changes in land surface temperature. To find out how big the relationship between these two things is, correlation analysis was carried out using linear regression analysis methods and spatial analysis methods. The results of this research are very significant changes in LST area from 2012 to 2022 with temperatures of <35°C in the Sawangan, Bojongsari, Tapos, Pancoran Mas and Limo sub-districts. Meanwhile, at a temperature of >40°C, very significant changes occur in the areas of Cimanggis, Cinere, Beji, Tapos and Sukmajaya sub-districts. The correlation between LST and NDVI in 2012 and 2022 has a strong negative correlation, which shows that the greater the NDVI value, the LST value tends to decrease.
