Abstract

Land cover in the Katingan Hilir KPHP Unit XXX Forest Area has experienced a decline in forest function due to land conversion for agriculture, plantations, and illegal mining. This study aims to analyze land cover changes in the UPT KPHP Katingan Hilir Unit XXX forest area based on Geographic Information Systems in 2000, 2010, and 2020. The analysis was conducted using overlay techniques and field validation through ground truthing. The results showed that in 2000, natural forest covered 149,676.80 ha (59.77%), declining to 127,254.95 ha (50.82%) in 2010, then slightly increasing to 130,145.92 ha (51.97%) in 2020. The deforestation rate during 2000–2010 reached 2,038.35 ha/year (1.36%), slowing to 321.22 ha/year (0.25%) during 2011–2020. Cumulatively, the deforestation rate from 2000 to 2020 was 976.54 ha/year (0.65%). Oil palm plantation expansion and mining were identified as the primary drivers of land cover change. The findings indicate significant anthropogenic pressure on the forest area, necessitating more targeted and sustainable area management.
