The main indicators Of the environmental aspects measured by the rate Of waste reduction, economic indicators measured by Cost Benefit Analysis method while social indicators measured by the level Of community participation. The efficiency Of waste reduction in Cibangkong was smaller which only 49.5 IJday at 0.84% compared to Cilengkrang which has 80.53 L/day. The benefits Of waste reduction to society was best perceived by Cibangkong (0.535 points) than Cilengkrang (0.465 points). The results Of WRT method, the level three aspects Of sustainability, Cilengkrang has a score Of 0.546 meanwhile Cibangkong only at score Of 0.454.
