Tempeh is a traditional soybean product originating from Indonesia. Tempeh is a high-protein food, which costs less per unit than other animal protein sources. However, the Tempeh industry will produce waste with this process. Tempeh production process requires a lot of water to boil, soak, and wash soybean skin. The research problem is that the practice of Tempeh industry has not managed wastewater well, which has the potential to cause the quality of tempeh industrial wastewater to exceed quality standards and cause negative impacts on the environment and society living around the industry, so alternatives are needed to improve wastewater management. The alternative is to convert liquid waste into renewable energy. It refers to the SDGs agenda for seven objectives (7) to improve clean energy research and technology, including renewable energy, energy efficiency, and sophisticated and clean fossil fuel technology. Biogas is a type of biofuel that comes from living things and renewable energy. This research aimed to determine the type of biogas that is appropriate for small-scale industries by utilizing Tempeh liquid waste with a mixture of household organic waste. The results showed that the biogas digester balloon is the type that is suitable for small scale industries. The selection of balloon digester is reviewed from the technical aspects, economic aspects, environmental aspects, and social aspects. Biogas is the right technology to convert tempeh waste into energy so that it can obtain economic and environmental benefits.
