EFFECT OF SERIES CIRCUIT ON THE LACTOSE BIOELECTRICITY OF A MICROBIAL FUEL CELL SYSTEM USING LACTOBACILLUS BULGARICUS
ABSTRACT: The need for
alternative energy, especially electricity at this time is increasing. The
decreasing amount of fuel that cannot be updated, encouraging scientists to
conduct researches in finding alternative energy sources which are
environmentally friendly, one of the alternative energy is the Microbial Fuel
Cell (MFC). The research on the effects of a series circuit on the production
of lactose bioelectricity microbial fuel cell system using Lactobacillus
bulgaricus has been conducted. This study aim was to assess the effect on the
production series circuit lactose bioelectricity MFC system using microbes
Lactobacillus bulgaricus. Stages of research included a microorganism
preparation of Lactobacillus bulgaricus, and measuring the potential difference
in a single, series 1 and series 2 circuits in the MFC system. The potential
difference on the measurement of a single, series 1 and series 2 on the
substrate lactose were 45 mV / 100mL; 57 mV / 100mL; 58 mV / 100mL respectively
where the power were 105.75x10-6 mW; 136x10-6 mW; 139.2x10-6 mW. These results
suggested that series circuit was able to increase the potential difference and
power on the substrate lactose and tofu whey the MFC system according to Ohm’s
law.
