Abstract

Abstract Marine sediments of Kendari Bay has the potential as an alternative source of electrical energy through sediment microbial fuel cell (SMFC) due to the high level of sedimentation. This study aims to optimize the amount of electrical voltage that can be generated through the SMFC system using stacked SMFC in the form of a series connection. The research methods include determining the sampling location, physical-chemical properties measurement of sediments, SMFC assembly (single and stacked SMFC), and electrical voltage measurement. Three station points representing the overall condition of Kendari Bay are determined as sampling locations. The result shows that there was a decrease in the organic matter content of the sediment substrate after the use of SMFC namely organic carbon from 2.78 percent to be 2.68 percent due to microbial activity in sediments. The single SMFC from station 2 (S2) can produce the maximum electrical voltage of 438 mV which then optimized using stacked SMFC in series connection. The maximum electrical voltage of 2.174V can be obtained using stacked SMFC. These results show that marine sediments of Kendari Bay is interesting as an alternative energy source through SMFC and stacked SMFC could optimize the amount of electrical voltage from single SMFC.
