Abstract
Land use change in the Bangsal Sub-Watershed, Mojokerto Regency, has significantly affected the region’s biophysical conditions and increased the vulnerability of soils to erosion. This study aims to identify land use changes in 2012, 2018, and 2024, as well as analyze their influence on soil erosion rates. The Universal Soil Loss Equation was applied to estimate actual soil loss across various land use units, while spatial mapping and analysis were conducted using a Geographic Information System. The results indicate that the conversion of forested and mixed-crop areas into agricultural fields, shrublands, and open land contributes to higher C and P factor values, thereby increasing erosion rates. Areas with steep slopes and low vegetation cover exhibited the highest erosion hazard levels throughout all observation periods. Spatial analysis further revealed a progressive increase in erosion intensity in relation to declining vegetation cover and intensified land use activities. This study recommends the implementation of conservation practices such as terracing, ground cover planting, and agroforestry-based land management to reduce erosion risks. The findings are expected to support more sustainable land management planning within the Bangsal Sub-Watershed.
