Integrated animal culture and soilless techniques are the technological combination between organic animal and plant production. This model consists of native breed chicken raising on high density walking catfish pond, plant production such as lettuce, hydroponic system, using waste water from animal rearing by means of organic nutrient film technique (ONFT), and plants production in organic substrate culture- chili and tomato production using chopped coconut pericarp. Waste water from animal rearing is the source of water and nutrient supply. For the effectiveness of resources using, the rest of water from many system was supplied to surrounding plants. At 4 weeks, the results showed that the lettuce production in ONFT can be grown although its growth rate was less than that of lettuce production in nutrient solution using Macbils and Torrey (1965) method, at EC 1.2 dS/m. The application of Trichoderma harzianum in walking catfish pond, can promote lettuce growth. There was no disease on lettuce and it was found negative for bacteria, pathogenic bacteria of plant pathology. Lettuce from ONFT is safe for human consumption because there are less pathogenic bacteria than normal standard and had low nitrate (153.3 mg/kg). Chili and tomato grown in chopped coconut pericarp were not significantly different to chili and tomato in mixed soil with chemical fertilizer. At 4 weeks, the average daily gain and feed conversion ratio of native breed chickens were 15 gram/bird/day and 3.93, respectively. In terms of walking catfish growth, the average weight gain was 102 gram/fish. From the above results, it was found that integrating the technologies of organic agriculture for both plant and animal production, can be effective. It is a suitable alternative of sustainable organic agriculture for the farmer.
