Identification of Surface Temperature Relation to Total Suspended Solid in Beratan Lake Using Multi-Temporal Remote Sensing Imagery

Abstract

This study aims to find out the correlation between lake surface temperature and the distribution of sedimentation from Landsat 8 OLI/TIRS imagery. As it is known that the Lake Beratan area is a tourism area that continues to grow and experiences changes in land use. As a result, the Beratan Lake area experiences changes in surface temperature and pollution both directly and indirectly and is supported by the potential for silting due to lake sedimentation. Therefore, a quick study is needed to carry out monitoring through an approach with remote sensing imagery using the SST and TSS methods in the identification carried out. The results show that the low (r2= 0.47) relationship or not relationship between the surface temperature of the lake and the sedimentation that occurs, even so, there is a decrease in surface temperature that occurs as a result of changes in the microclimate that exists in the tourism area of Lake Beratan.
