Abstract

Ceramic as low cost separator membrane has widely applied in dual chambered Microbial Fuel Cell (MFC). Its big pores and other chemical and physical advantages make it suitable to substitute expensive exchange separator membrane. The purpose of this study is to enhance the electricity of ceramic based microbial fuel cell by using multiple number of carbon electrode pairs. However, the study of ceramic with multiple carbon electrode pairs has never been published before. This study use tempe waste as anolyte and KMnO4 as its catholyte to gain electricity. Tempe waste is incubated for 24 hours before using. Running of the MFC is 48 hours straight with voltage and current check every 2 hours. Three variety of electrode pairs are checked together in the same interval. Those data processed statistically using Analysis of Variance (ANOVA) test to examine the significant difference of the voltage, current, and power density as the parameters. The result of this study shows that the electricity of three electrode pairs has the higher average of power density with the number 1447,91 mW/m2 , the difference between three and two electrode pairs is around 588 mW/m2 and between three and one electrode pairs is 910 mW/m2 . It has significant difference between one, two, and three electrode pairs in the parameters. Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) dropped down after the running system.
