Abstract:
Land use change or land change can affect the ability of land to resist erosion. Vegetated land has a stronger erosion resistance than non-vegetated land. The level of criticality of an area's land can be seen from the amount of erosion. This study is purposely to identidy areas that have the potential for erosion based on their greenness index and also their slope. The method used is integration between NDVI (Normalized Difference Vegetation Index) and Slope by utilizing Landsat 8 satellite imagery recorded in 2014, Sentinel 2A satellite imagery recorded in 2018 and 2021, and Digital Elevation Model (DEM) data. Based on the analysis, it was found that the class levels of erosion potential were different in the three periods. The results showed that the Riam Kanan catchment area was dominated by very light erosion potential classes because the Riam Kanan catchment area was still dominated by green land. The potential for very light erosion occurs on predominantly green or vegetated lands such as secondary forests and rubber plantations. Meanwhile, the heavy erosion potential class occurs on land with minimal vegetation such as shrubs and mining land.
