Abstract

Lake Rawa Pening in Semarang Regency plays a crucial ecological role for Semarang Regency, namely as a buffer zone and a national priority area. High levels of anthropogenic activity have caused ecological damage in the form of high sedimentation rates and the blooming of water hyacinth colonies. This study aims to identify the causes of ecological damage in the Lake Rawa Pening area based on the extraction of vegetation index values. The methods used are spatial classification and spatial descriptive analysis utilizing remote sensing data from Landsat 8 satellite imagery from 2023. The results of the study indicate a strong ecological relationship between land and water bodies. The lake’s riparian zone is dominated by low to very low greenness levels due to land-use conversion and intensive agricultural activities. The conclusion of this study emphasizes that the management of Lake Rawa Pening cannot rely solely on mechanical rehabilitation of the water body, but also requires preventive measures focused on restoring natural vegetation cover in the lake’s riparian zone to mitigate the ongoing rate of environmental degradation.
