Desain Digester Biogas Berbahan Baku Eceng Gondok

The process of biogas formation of water hyacinth causes the pH of biogas to be acidic before the formation of methane. Biogas digester made from metal drums causes the digester to undergo corrosion and leakage. This digester is not effective because it can only be used for once biogas production (Mulyati, 2015). In this study aimed to design a suitable digester for acidic conditions so it is not easy to leak and digester can be used more than once. In this study, the design of biogas digester from water hyacinth using plastic drum sized 200 liters. The design of digester biogas is using value engineering method. The size of biogas digester is: 28 cm diameter and 90 cm long consisting of top and bottom cleanouts. This digester is supported with a portable framework for easy removal. Portable frame size is 93 cm wide by 67 cm long and 72 cm high, 10 cm high wheel, height of skeleton to 10 cm drum with 2 mm hollow iron thickness. Furthermore, a biogas test is made from water hyacinth using this digester. This digester produces a gas that can be seen from the flame. This The digester is also acid-resistant because it does not leak for use more than once
