KAJIAN PELUANG PENERAPAN PRODUKSI BERSIH DI INDUSTRI TAHU (Studi Kasus pada Beberapa Industri Tahu di Kota Martapura, Sumatera Selatan)

Abstract

The production process in some tofu industries face some problems, both in the production process,
industrial management, and environmental management. This research aimed to find out strategies to improve
efficiency in tofu production through materials, water and energy saving and to improve environmental quality
through minimization and utilization of waste with cleaner production options. The method used was a cleaner
production audit by identify problems until analyzing the feasibility of several aspects. The research was conducted
in three tofu factories with a daily production capacity of 80 kg/day (Factory A), 220 kg/day (Factory B), and 500
kg/day (Factory C). Based on the research results, some problems were identified on various aspects and some
recommendation alternatives of cleaner production in the three factories are identified covering: washing
soybeans gradually, re-filtering the remaining washing and soaking water, using a boiler for cooking with steam
system (factory A only), Good Manufacturing Practices (GMP), utilization of solid and liquid waste. If cleaner
production is implemented, the total energy consumption per kg of soybeans from the three factories could be
decreased to 15.87; 20.69 and 8.63 MJ/kg of soybeans, respectively. The percentage reduction in waste water
would range from 24.76-36.08%. Tofu production could be increased by 5.19%, the utilization of firewood could
be reduced by 64.42% and the savings obtained would range from 2.2-16.9 million rupiah/month. Based on the
results of the quantitative feasibility analysis, the five cleaner production options are feasible and should be
applied in practices.
