Abstract
Transformation of land uses from several semi-arid agroecosystems in Indonesia: forest to settlement, dryland agriculture, and others had affected to soil erosion. This study was conducted to evaluate soil erosion at semi-arid Manikin Baki watershed, West Timor, Indonesia. USLE method was used to predict soil erosion supporting ArcGIS 10.3 software. The results showed that the highest soil erosion occurred at dryland farming (60.22% with total land cover 11% of total areas), while the smallest one went to the forest (0.20% with total land cover 42% of total areas). Another finding that soil erosion at Manikin Baki watershed was dominated by class I (12,251.77 Ha; 64.38% of total areas), while the smallest one was majored for class IV (1.59% of total areas)
