Abstract

Tofu has been consumed and favored by most of Asian. Indonesian Central Bureau of Statistics said that the average consumption of tofu in 2017 was about 0,15 kg/person/week. On the other hand, the higher level of tofu production, of course the level of waste contamination is also higher. So that cleaner production is one of the effective approaches to reduce tofu industry waste. This study aims to analyze the stages of tofu production in SME that produce the most liquid waste, what parameters exceed the quality standards, and determine the alternative of cleaner production strategies for tofu production. This research analyzed mass balance, Activity Relationship Chart, Activity Relationship Diagram, waste characteristics test, and alternative selection of cleaner production with pairwise comparison. This research found out that stages which produced the most waste were the treatment and waste disposal process. The highest priority and the most possible alternative of cleaner production to be implemented were waste separation at each stage, waste water recycle, and water vapor recycle.
