In this study, the concept of Microbial Fuel Cells (MFCs) is applied in the biological cathodic protection (CP) system. MFCs are a promising technology for electricity production from a variety of materials. Impressed current cathodic protection (ICCP) was the tradition method used in corrosion control method. Biological CP uses the microbiological presence in wastewater to generate the electrons. The focus of this study is on the effect of organic waste towards the biological CP system. The selected organic wastes are orange peel and pineapple peel. The presence of starch and sugar in the organic waste are promote the microbial growth and increase the performance of biological CP system. The method used to prepare the substrate was based on the previous studies and the CP system was a single chamber system. Current and power density was calculated from the experimental data of the specific weight of substrates and the results was discussed in this study. The weight of substrate are manipulated for each experiment. The statistical analysis was done on the voltage potential output for the selected optimum substrate’s weight and the result was varies for each of organic waste used. The highest voltage potential output by the CP system was 920 mV (20 grams of orange peel) and 1046 mV (40 grams of pineapple peel).
