In the Badeng Watershed of Banyuwangi was a flood that resulted in erosion and landslides. The amount of kinetic energy of rainfall can erode the soil layer, leading to high rainfall erosivity. The purpose of this study was to determine the rainfall erosivity and erosion rate with the MUSLE method using the Geographic Information System in the Badeng Watershed. Predict the level of land erosion using the MUSLE (Modified Universal Soil Loss Equation) method with four parameters namely the runoff erosivity factor (R), soil erodibility factor (K), slope factor and slope length (LS), and plant management and soil conservation factors (CP). In the erosivity analysis comparing the MUSLE equation with the erosivity methods of USLE, Abdurachman, Bols, Lenvain, Soemarwoto, Utomo-Mahmud, and Bols-Luliro to check the equations of other methods that can be applied according to conditions in the field. The rainfall erosivity equation besides the MUSLE method that can be applied in the Badeng watershed is the Soemarwoto’s method. The total erosion rate in the Badeng watershed was 13,037.07 tons/ha/year or 825.13 mm/year. The high erosion hazard level zone was found in the forest in the mountainous area of Sumberarum Village with an area of 0.002 km2, that need for reforestation. Mechanical conservation needs to be made terraces and mounds in agricultural areas in Mangaran Hamlet, Sumberarum Village with an area of 0.006 Km2.
