Main Article Content


Research with the aim of utilizing and processing dangke, whole milk, and whey as substrates in Microbial Fuel Cell-based research has been successfully conducted. The substrates were placed in anode chamber and KMnO4 electrolyte solution was used in cathode chamber. The two chambers were then connected by a salt bridge. The Saccharomyces Cerevisiae microorganism was used as a catalyst compound. The highest voltage measurement results for each substrate were obtained at 659 mV for dangke, 670 mV for whole milk, and 998 mV for whey. The current measurement on each substrate of dangke, whole milk, and whey, respectively, it was 0.29 mA, 0.23 mA, and 0.37 mA. In general, the measurement results show that the MFC made using whey substrate has the best quality with a power density of 9.23 x 10-3 W/m2. Thus, whey can be considered a promising alternative source of electricity by converting organic compounds.
