【 摘 要 】

Location determination is based on the compilation of soil type's map, land use map and slope map. Uniformity of soil type, slope and land use is classified into one unit of land, so that there are 48 units of land to be use as sample points. The purpose of this research are to identify patterns of land use, determine the amount of erosion, the amount of erosion that is tolerable and erosion control through a conservation plan based on local wisdom. The erosion prediction used USLE method, erosion of tolerated (Edp) using the formula Hammer. Results of laboratory and field observations having analyzed using USLE showed some level of erosion on land use in the Kintamani classified from very mild to very severe: 4.79 to 370.60 t ha-1yr-1, while Edp ranges from 30.00 to 48.00 t ha-1 yr-1. erosion Severe to very severe found on the use of mixed garden/citrus garden, dry land and shrubs/ reeds. The planned of use of land is intercropping annuals with horticultural crops (cabbage), citrus trees intercropped with flower of gumitir and bush land planting with elephant grass on a slope of less than 25% and planted of trees on land with a slope above 25%.
