Abstract
Indonesian government has committed to realize the goals of sustainable development in the field of energy as stipulated in Government Regulation Number 79/2014 on national energy policy. A feasibility study of the utilization of alternative energy is important for developing countries like Indonesia. It is expected to reduce dependence on fossil fuel use and meet the energy needs on rural areas in Indonesia. Microbial fuel cells (MFCs) is a potential source of electrical energy from waste that is rich in organic matter. Trends in research and development of Microbial Fuel Cells (MFCs) technology are increasing every year due to great opportunity to address a wide range of issues related to renewable energy needs, restoration of contaminated environment, water treatment electricity generators in remote areas and many more. MFCs can be used to treat domestic waste, biomass, algae, landfill leachate, agricultural runoff, and industrial waste. MFCs technology is a technology solution for cheap, fast, simple. MFCs use of technical challenges including low electricity production, current instability, and high internal resistance. Many challenges must be address, including a more detailed analysis in energy production, consumption, and application, understanding the relationship between the amount of electricity and contaminant removal, promoting the elimination of nutrients and optimizing system configuration and operations.
Highlights
Microbial Fuel Cells (MFCs) is a bio-electrochemical devices that capable to produce electrical current directly from organic substances due to metabolic activity of microorganism / bacteria from waste or spesific substrate [1]
Microbial fuel cells (MFCs) are applied on field scale to monitor remote areas and combined with other treatment unit to treat wastewater
MFCs are able to convert chemical into electrical current directly and perform biochemical reactions in the absence of additional energy in the cathode chamber. This technology is still difficult to apply due to highly cost of MFC material fabrication and low power generation [11]
Summary
Microbial Fuel Cells (MFCs) is a bio-electrochemical devices that capable to produce electrical current directly from organic substances due to metabolic activity of microorganism / bacteria (release of electrons outside the cells) from waste or spesific substrate [1]. MFCs can independently treat wastewater or integrated with other treatment units [2, 3] This interesting technology can be more competitive due to its sustainability in generating green energy. MFCs are able to convert chemical into electrical current directly and perform biochemical reactions in the absence of additional energy in the cathode chamber. This technology is still difficult to apply due to highly cost of MFC material fabrication (electrode, proton exchange membrane and mediator) and low power generation [11]. Other substrates such as wastewater fisheries [19], vegetable bins [20], cow rumen [21] and wastewater from tempeh industry [22] may be used as MFCs substrate
