Dampak perubahan penggunaan lahan terhadap land surface temperature di Desa Papringan, Kecamatan Kaliwungu, Kabupaten Semarang berbasis pengindraan jauh

Abstract

Background: Semarang Regency is one of the northern coastal areas of Java Island which experiences an increase in population every year. This has led to a change in the use of green open spaces in residential areas. This research aims to determine the effect of changes in vegetation on surface temperature (land surface temperature or LST). Methods: This research uses remote sensing methods with ArcGIS 10.3 software using Landsat 7 image data for 2002 and 2012 and Landsat 8 for 2022. Finding: The results of the research show that changes in vegetation affect LST. This can be seen from the correlation value which shows a sufficient correlation in 2002 and a strong correlation in 2012 and 2022 and has a negative value which indicates that the higher the vegetation density value, the lower the surface temperature. The highest NDVI value was in 2012 with a vegetation density area of ​​160.2796 hectares and a dominant temperature in the range of 27.5-30°C. Apart from vegetation density, factors related to LST are human behaviour, such as open burning of waste. Conclusion: One mitigation that can be used to deal with climate change is the climate village program, such as increasing vegetation cover, low-emission agricultural cultivation, as well as waste, solid and liquid waste management.
