Low Power Electrical Generator from Soil Microbial Fuel Cell

The alternative energy is needed for remote area such as North Kalimantan Province. One of local potential of the province for renewable energy is peat soil. The aim of this study is to harvest electricity from Soil Microbial Fuel Cell. The dimension of SMFC is 18 cm × 11.4 cm × 38.7 cm. In this study we used two parallel array of SMFC. The coconut water is used to increase the humidity of soil to produce higher electrical power. The data measurements generated by SMFC are monitored for 7 days. The maximum power from SMFC is 98.2 mW. The result shows that The SMFC is able to turn on the lights for 900 minutes with the maximum light intensity produced at 5.260 Lux while the maximum intensity of light if using AA battery is 21.900 Lux. Therefore SMFC is highly recommended for remote areas in North Kalimantan for electrical sources.
