%X Research to study the effect of variations in the concentration of KMnO4   as a catholite on Microbial Fuel Cell (MFC) based on tempe waste and pottery  membranes has been carried out. This study aims to determine the electricality  and reduction of COD anf BOD of tempe waste on MFC substrates based on  variations in the conceration of potassium permanganate catholite (KMnO4). The  MFC used in the form of a dual chamber with a pottery membrane as a cation  exchange, the anode chamber containing the tempeh liquid waste substrate and  the cathode space containing the KMnO4 solution varied from 0.10 M, 0.15 M  and 0.20 M. This research was conducted for 48 hours and Measurement of  voltage and current is carried out every 2 hours. The parameters used are voltage  (V), current strength (mA), power density (mW / m2), as well as Chemical Oxygen  Demand (COD) and Biological Oxygen Demand (BOD) of waste before and after  running. The data obtained were processed statistically using the Analysis of  Variance (ANOVA) test to determine the significance of differences in  concentration variations in each parameter. The highest average electricity was  obtained at a concentration of 0.15 M of 950.3185 (mW / m2), while the decrease  in COD and BOD waste obtained the highest decrease at a concentration of 0.20  M, a decrease in COD reached 96.28% and BOD reached 68.26% . Parameters  of power density, COD and BOD of all variations of KMnO4 each produced  significant numbers based on the ANOVA test. The significance of this parameter  indicates the influence of KMnO4 on the MFC system.
