The Krueng Peutoe watershed located in North Aceh district is one of the sub-watersheds of the Jambo Aye watershed. The purpose of this study is to develop a plan for sustainable agricultural land use in the Krueng Peutoe watershed. The method used consists of 1) overlay map, 2) field survey, 3) evaluation of land capability, 4) evaluation of cropping and agrotechnology patterns, 5) erosion prediction, 6) socioeconomic analysis, and 7) cropping and agrotechnology recommendation. The results showed that, evaluation of land capability classification (KKL) II with slope limiting factor be discocered inhomogeneous land units (SLH) 15 and 10, KKL III with slope limiting and erosion factors at SLH 16, slope limiting factor at SLH 1, 5, 9, and 12. KKL VI with slope limits factors in SLH 3, 4, 6, 7, 8, 14, and KKL VII with slope limiting factors in SLH 17. The results of erosion prediction in mixed gardens were 14.56 - 403.82 tons/ha/year and greater than tolerance erosion (ETol) (23.03 - 39.60 tons/ha/year), resulting in a decrease in land productivity where farmers' income ranges from 754,000 IDR - 7,434,000 IDR/KK/year. With the improvement of cropping patterns followed by agrotechnology and the addition of side businesses (the results of calculations), there was a decrease in the value of erosion to 1.09-30.28 tons/ha/year followed by an increase in farmer's income (10,267,200 IDR - 12,441,060 IDR/KK/year). The result of planting pattern recommendation as follows: KKL II and III need to be worked improvement of planting pattern and agrotechnology. KKL VI carried out the application of agrotechnology with the planting of terrace reinforcing plants and planting according to contour. The use of forest land in the same class is recommended nonetheless as a forest, while the use of land for shrubs in the same class is recommended for pasture.
