Abstract
Land use-land cover (LULC) is one of the indicators commonly used in monitoring the quality of natural resources. Mostof the Ogan watershed is a peat ecosystem that plays an important role in maintaining the balance of the ecosystem andwater supply. During the 2014-2019 period the Ogan watershed experienced several wildfires and infrastructure development,particularly freeways. This study aims to analyze changes in the LULC in the Ogan watershed during the 2014-2019 period.LULC analysis uses remote sensing technology by utilizing Sentinel and Landsat satellite imagery data. LULC identificationused the visual image interpretation method, while LULC changes were analyzed using the GIS technique with the spatialoverlay method. The results showed that changes in LULC led to the LULC managed class, where the increase in areaoccurred in the rubber and oil palm plantation classes. Meanwhile, the highest reduction in area occurred in the dry landforest class. Changes in LULC that occurred during the observation period had a negative impact on the watershed in theform of land degradation, decreased levels of biodiversity and increased fire vulnerability. Based on these results, land use inthe Ogan watershed needs to be controlled and land management practices must pay attention to environmental sustainabilityaspects.
