Microbial fuel cell (MFC) is a technology that can produce electricity with helping exoelectrogenic
bacteria. The technology can also utilize fishery processing wastewater as a media for bacteria to live, so
it can reduce organic pollution load in the wastewater. Purpose of this research was to identify the effect
of electrodes distance to electricity and water quality parameters of fisheries processing wastewater using
MFC technology.. The MFC system used was single chamber system. The distance between electrodes used
were 2 cm, 4 cm and 6 cm and the electrodes were made of stainless wire mesh coated with chitosan and
active carbon. The results showed that electrodes distance affected to MFC electricity within salted boiled
fish wastewater media. The average value of electric current during 48 hours observation on the distance
of 2 cm, 4 cm and 6 cm were 0.17±0.06 mA, 0.46±0.17 mA and 0.44±0.16 mA, respectively. Average values
of electric voltage on the distance of 2 cm, 4 cm and 6 cm were 0.12±0.03 V, 0.34±0.07 V and 0.37±0.08 V,
respectively. The research also showed that MFC system can decrease average value of BOD 20.5%, COD
30.41%, and TAN 21.2 % of salted boiled fish wastewater media.
