Abstract
Energy is a very fundamental necessity in human life. Current energy usage is highly
dependent on the surrounding environment. Especially in remote areas, which require
simple energy instruments such as batteries or fuel cells. The Fuel cell is an energy
instrument that transfers electricity from a rechargeable source using external materials.
Microbial Fuel Cell (MFC) is an alternative form of environmentally friendly energy that
is commonly used as a source of energy in the future. MFC is an energy instrument that
can convert chemical energy into electrical energy through catalytic reactions by
utilizing microorganisms. Plant waste tofu and fishery waste is a waste that contains a lot
of carbohydrates, proteins, and fats that usually cause heavy pollution to the waters. By
utilizing the liquid waste itself is one way of solving problems in the environment and
lack of energy by using the MFC system. For the experiment, this time aimed to compare
the electrical energy generated between waste plant tofu and sewage fisheries. In a
strong MFC experiment current on plant waste knows an increase as much as 1.47% of
fisheries waste, while for voltages in the trial MFC waste fisheries have increased by
1.19% from tofu plant waste.
