Analisis Perubahan Kerapatan Vegetasi Pegunungan Kendeng Utara Kabupaten Pati Menggunakan Citra Sentinel-2A

Abstract

The landform of Pati Regency’s part of North Kendeng Mountains which is located on the south of Pati Regency (DONE). Land use in this area is dominated by forest areas and dry agricultural land. Reduced vegetation due to misuse of space and resources is a problem that causes geological and hydrological disasters in these mountains and the areas below them. This study aims to determine changes and condition of vegetation area in the North Kendeng Mountains in Pati Regency. The method used to determine the density of vegetation in this study is based on the Normalized Difference Vegetation Index (NDVI) analysis using Sentinel-2A imagery recording in 2017 and 2022. Vegetation conditions are divided into dense, fairly dense, non-dense, non-vegetative, and water/cloud vegetation classifications. Based on the results of image processing, the dense vegetation class did not experience the highest increase in area of 359.68 hectares. The highest decrease in area was found in the fairly dense vegetation class with an area of 243.34 hectares. The decrease in vegetation class decreased by 175.12 hectares. The non-vegetation class increased by 58.51 hectares and the body of water/cloud area increased by 0.27 hectares. The results of the research on the case of land use change in the North Kendeng Mountains in Pati Regency.
