Spatiotemporal Analysis of Land Surface Temperature Changes by Vegetation Density in Central Lombok Regency

Abstract

Land surface temperature is different from air temperature and is caused by various things, one of which is due to changes in vegetation density. Central Lombok Regency is one of the locations that has experienced massive and well-known development in Indonesia. Based on these circumstances, this research was conducted with several objectives, namely: to determine changes in vegetation density, as well as changes in land surface temperature in Central Lombok Regency in 2018 and 2023, and prove the relationship between vegetation density and changes in land surface temperature. The research method used in this research is descriptive quantitative because it involves numerical data, to find the relationship of vegetation density to changes in land surface temperature. In addition, this research also uses the NDVI method to determine the level of vegetation density, and LST to determine the land surface temperature there. The results showed changes in vegetation density and changes in land surface temperature in Central Lombok Regency. The average change in vegetation density and land surface temperature occurred in the Central region of Central Lombok Regency which is the economic center area. Then there is a strong relationship between vegetation density and land surface temperature changes.
