Abstract:
This study is quantitative research employing survey techniques and spatial modeling. In the research area, particularly in forested areas, the
Normalized Difference Vegetaton Index (NDVI) values range from 0.25 to 0.55 with Land Surface Temperature (LST) values of 29°C to 37°C.
Cooler temperatures below 34°C were observed in the southwest (outside the mining area). The LST values indicate high temperatures above
37°C in the coal mining area, with effects extending up to 6 km. The linear regression equation between NDVI and LST in the coal mining area,
with a regression equation of y = -20.888x + 40.458; R^2 = 0.83; r = -0.91, shows an inverse relationship between NDVI increase and ground
surface temperature, indicating a good model fit with the data and a strong negative linear relationship between the two variables. The Urban
Heat Island (UHI) effect in the mining area, especially at the mining center, shows a UHI with a temperature difference of more than 0.6 degrees
Celsius compared to the cooler surrounding area. At the center of the coal mining area, the TVDI value is 0.6-0.8 (high-very high), but in the
eastern part of the mine in forested areas with a certain soil type, the TVDI value is 0.2-0.6 (moderately dry - dry), while in other parts of the
forested area with a different soil type, the NDVI value is < 0.2 (moist). There is a difference in response to different soil types. Drought increases
in the forested areas around the mining site, affecting ecosystem productivity and soil moisture.
