Cibodas Village is one of the areas in West Bandung District that has potentials as the producer of organic vegetables. However, many problems are faced by organic vegetables farmers such as narrowing arable land, limited capital, organic certification and renewal cost, and higher cost of labors. These limited resources can constrain the farmers and will affect their income. The research aims to optimize organic vegetable farming to maximize the income of farmers and analyze the sustainability of organic vegetable farming in Cibodas Village. The method used is a survey method. Sampling collection method is done by census, and with population of farmers who practice organic vegetable farming and have organic certificates. Total respondent is 10 (ten) farmers. The type organic vegetables with intercropping cultivated system is 10 (ten) combinations, namely broccoli-tomato, cabbages-tomato, cauliflower-tomato, lettuce-tomato, bean-tomato, broccoli-cucumber, cabbages-cucumber, cauliflower-cucumber, lettuce-cucumber, and bean-cucumber. Data were analyzed using farm income analysis, optimization analysis with linear programming approach using software Microsoft Excel Solver, and sustainability level analysis of the farm, which are determined by a scoring system indicator with four aspects from ecological, economic, social, and institutional perspectives. The Result showed the actual income of each farm organic vegetable intercropping are: (1) broccoli-tomato Rp 23.396.088,-/ca (cultivated area); (2) cabbage-tomato Rp 18.660.865,-/ca; (3) cauliflower-tomato Rp 32.954.105,-/ca; (4) lettuce-tomato Rp 17.978.344,-/ca; (5) bean-tomato Rp 18.197.195,-/ca; (6) broccoli-cucumber Rp 3.670.694,-/ca; (7) cabbage-cucumber Rp 5.284.697,-/ca; (8) cauliflower-cucumber Rp 3.595.697,-/ca; (9) cabbage-cucumber Rp 4.409.697,-/ca; (10) bean-cucumber Rp 4.904.197,-/ca. Based on the optimization analysis with linear programming approach, the type of organic vegetable farming with intercropping systems that generates optimal revenues for farmers are with following orders: (1) broccoli-tomato; (2) cauliflower-tomato; (3) lettuce-tomato; (4) bean-tomato; (5) broccoli-cucumber; (6) cabbage-cucumber; and (7) cauliflower-cucumber. More over, the result showed that these combination of organic farming with intercropping system does not have the optimal result, and the combinations are cabbage-tomato, cabbage-cucumber, and bean-cucumber. Number of remaining capital (reserves) can be used to allocate additional resources that have shadow price value. Organic vegetable farming sustainability index in Cibodas Village amounted to 67,98% and is categorized as moderate sustainable. Ecological aspects (85,56%) and institutional aspects (76,00%) are in a very sustainable status, and economic aspects (62,04%) are in the status of quite sustainable, while social aspect (48,33%) are in the status of less sustainable.
