Performance Enhancement of Microbial Fuel Cells from Fishery Wastewater Using Boost Converter Device

Electricity is a basic necessity in everyday life. Fossil energy is typically used to generate electricity, and non-renewable energy sources will eventually be depleted without innovation in the form of renewable energy. Liquid waste from fisheries is a commodity that can generate electricity through Microbial Fuel Cell (MFC) systems. However, the electricity generated is relatively small. The research aimed to increase the electrical voltage from fish curing waste in a Microbial Fuel Cell system by using an additional boost converter circuit. The research was conducted using 5 MFC systems connected in series and connected to a boost converter device. The electrical values of the MFC system with the boost converter circuit were a voltage of 12.13±0.87 V, a current of 0.86±0.20 mA, and a power of 10.50±3.11 mW. Meanwhile, without the boost converter circuit, the voltage value was 2.24±0.26 volts, the current was 0.17±0.03 mA, and the power was 0.38±0.11 mW. The increase in electricity in the MFC system indicated that the boost converter circuit functioned properly. The MFC system was able to reduce BOD, COD, and TAN values.
