| Summary: | The research aims to recommend optimum land use allocation that can control soil surface erosion in Wuryantoro sub-watershed. The research was done using land evaluation approach to land unit and analyzed based on area function allocation, land capability classification, and erosion hazard rate. Optimization analysis on land use allocation was done statistically through linear program symplex method using QSB software.
The results showed that actual land use caused actual soil surface erosion (A) of Wuryantoro subwatershed was higher than tolerable erosion (T) threshold. Optimization analysis recommends that to control actual soil surface erosion (A) to be lower than tolerable erosion (T) threshold, it is needed to convert all actual land uses of groves and croplands to forest. Actual land uses of production forests, community forests, irrigated
farmlands, rainfeed farmlands, and residentials could still be kept remain as they were.
