One alternative technology that can be developed is Microbial Fuel Cell (MFC) based on bioelectrochemical principles by utilizing microorganisms to break down substrates to produce electrical energy. This research is focused on the utilization of organic waste as a substrate in a singlel-chamber MFC system equipped with 19 electrodes. The variety of substrates includes tomato fruit waste, and mixed waste which includes various types of fruits and vegetables. Variations in substrate incubation time were also carried out, namely for one to three days. The highest value of electricity production was produced by mixed organic waste which was incubated for 3 days with a voltage of 6.2 V while tomato waste with the same incubation time produced the highest voltage of 6.1 V. Further research on the use of organic waste as a substrate in the MFC system can reduce the operating costs of the MFC system, as well as make MFC an economical, environmentally friendly and sustainable electricity generating technology.} }
