Abstract
Microbial Fuel Cell (MFC) is an alternative technology that can convert chemical energy into electrical energy through catalytic reactions using microorganisms. This research was conducted to determine strong current and electric voltage generated from the zinc, copper, and aluminum electrodes in the Microbial Fuel Cell system. The reactor used has two compartments. In this MFC system, the electrons generated by bacteria from the substrate in the anode compartment are transferred to the anode electrodes and flow to the cathode electrodes, while the protons are transferred to the cathode compartment via the salt bridge. Pond mud is used as a substrate in the anode compartment, distilled water in the cathode compartment, and salt bridges (NaCl 1M) as a proton transfer medium. Results of the research showed that the voltage and current have stable values. Based on the research results, it can be concluded that the production of electrical energy is produced by the combination of electrodes with copper and aluminum materials.
