FUJI ASTUTI FEBRIA, W.P. JONESTI AND INDRA JUNAIDI ZAKARIA

Abstract

Electricity can be produced using Sediment Microbial Fuel Cell (SMFC). The existence of microbes in the sediment was able to transform organic matter to produce electrons. This study was started from November to April 2017 at the Laboratory of Microbiology Research in the Biology Department, P3IN Laboratory of Soil Science, Andalas University. The objectives of the study were to determine the characteristics of estuarine sediments from Muaro Padang, West Sumatra, calculate the production of electric current that can be generated through SMFC, determine the sediment characteristics as SMFC substrate. Characteristics of Muaro Padang sediments were black mud soil, organic carbon 3.9%, total nitrogen 0.17% and phosphorus 82.075 ppm. Electrical current production peaked on the 20th day with a value of 432.69 mA/m2. The SMFC substrate changed color to brownish on the surface with 1.65% organic carbon, 0.25% total nitrogen and 53.881 ppm phosphorus.
