| Abstrak Abstract Soil erodibility is the sensitivity of the soil to erosion, the higher the erodibility value, the more easily the soil is eroded and vice versa, the smaller the erodibility value, the more difficult it is for the soil to erode. Soil erodibility is influenced by soil texture, soil structure, organic matter, and permeability. This study used a survey method. Soil sampling was carried out on several land uses, including rice fields, dry land agriculture, shrubs, and swamp shrubs. Soil samples were taken in 2 ways, namely intact soil samples and disturbed soils, the soil samples were then analyzed in the soil science laboratory to determine the physical and chemical properties of the soil. The results of the analysis of soil erodibility values ??show that the level of soil erodibility in the Wimbi sub-watershed has various criteria, namely, low, medium, rather high, high, and very high. Land use with low criteria is primary dryland forest K= (0.18). while the medium criteria were shrubs K=(0,31), savanna K=(0,23) and secondary dryland forest K=(0,30). Land use with moderately high criteria is paddy field K=(0,37) and land use with high criteria is open land K=(0.46) and dryland agriculture K=(0.51). Meanwhile, land use with very high criteria is mixed dry land agriculture K=(0,56). The suggestion from this research is that further research is needed on the level of erosion hazard at each land use in the Wimbi sub-watershed for conservation research.
