The increase in population will encourage the community to transfer the function of agricultural land in the Malino sub-watershed. Land use dramatically affects the level of erosion and sedimentation. The use of SWAT models can identify, assess, and evaluate the extent of a watershed’s problems. This study aims to determine the spatial distribution of HRU and analyze the rate of erosion and sedimentation in the Malino sub-watershed. The results showed that the most HRU is found in secondary dryland forests, as much as 624 HRU (32.21%). The level of erosion rate of the category is very light with an erosion value of 5.21 tons/ha/year, light 31.19 tons/ha/year, moderate 104.91 tons/ha/year, weight 267.10 tons/ha/year, and hefty 616.74 tons/ha/year. The most significant sedimentation rate was found in sub-watershed 18 of 71.97 tons/ha/year and subwatershed 10 of 13.31 tons/ha/year.
