Recycle Strategy for Processing Waste of the Sanan Tempeh Industrial Centre: Prevention of Air Pollution

Abstract

The Sanan tempeh industrial center community, located in Malang, East Java, has a special strategy to maintain environmental resilience in the area. 500 SMEs inhabit and produce tempeh in an area of 20 hectares. Each SME processes around 100 kg of soybeans on average into tempeh. In fact, the production of tempeh, of course, produces a lot of waste. The waste generated is boiled water and peeled soybean seeds. Therefore, it can be imagined the environmental burden of supporting the Sanan community from any tempeh production waste that is produced. If they don’t have an adequate waste management strategy, it can pollute the environment in the Sanan area. To anticipate environmental pollution, especially air pollution from boiled soybeans, the residents of Sanan carry out a waste recycling cycle to minimize waste disposal. The research method was carried out through qualitative approaches, such as interviewing the management of community associations as representatives of the Sanan community and observing & documenting several Sanan residents’ homes in managing the waste of Sanan tempeh production. The results of the research show that the waste recycling strategy is manifested in several activities: boiled wastewater and remaining soybean husks have been used as cattle feed, while since 2018 cow dung from the Sanan farm has been used as biogas as energy for burning stoves for tempeh production. The benefit of this strategy is that there is no strong odor generated from the tempeh production process and it strengthens the Sanan’s environmental sustainability.
