“…If the anode and cathode are connected to a resistor, there will be a flow of electrons from the anode to the cathode, causing an electric current. Furthermore, protons and electrons will reduce Mn 7+ to Mn 4+ in the electrolyte solution of KMnO4, and reduce Fe 3+ to Fe 2+ in the electrolyte solution K3Fe(CN)6 [18].…”

The increasing consumption of electrical energy and still dependent on non-renewable energy has encouraged the implementation of effective, efficient, and environmentally friendly technologies to produce electrical energy. Microbial Fuel Cell (MFC) is one of the alternative technologies that utilize microorganisms in converting chemical energy from organic compounds under anaerobic conditions to be converted into electrical energy. The study was conducted to determine the potential of electrical energy generated from the treatment of eceng gondok waste (Eichhornia crassipes) with variations in the addition of buffer solutions and combinations of electrolyte solutions using the microorganism Saccharomyces cerevisiae through Microbial Fuel Cell technology. This study consists of three stages and methods, namely sample preparation, MFC media preparation, and analysis of pH, current, voltage, and power density. Measurement of the value of the maximum voltage, maximum current and power density is carried out every 3 hours for 27 hours for each treatment. The results were obtained as follows consecutively: firstly, for variations without the addition of buffers and electrolyte solutions are 0.25 volts; 0.08 mA; 13.05 mW/m2, secondly, with buffer and electrolyte solution KMnO4 0.2 M are 1.12 volts; 0.77 mA; 562.92 mW/m2, and thirdly, with buffer and K3Fe(CN)6 0.2 M are 0.47 volts; 0.48 mA; 147.26 mW/m2. Based on the results of the study, it was concluded that the most optimal variation in producing electrical energy was in the variation in the addition of a phosphate buffer and 0.2 M KMnO4 solution. Eceng gondok waste has the potential to be used as a source of electrical energy.

Microbial fuel cell (MFC) is a technology that utilizes bacteria in organic medium that can convert chemical energy into electrical energy. This technology can be used to treat fishery waste and shrimp waste which is rich in organic matter. This study aimed to measure the performance of the MFC system on fishery wastewater and shrimp wastewater as a means of producing bio-electricity while reducing the waste load. This study used different types of electrodes, including zinc, aluminum, copper, and carbon graphite. This technology used 0.2 M KMNO4 electrolyte solution. The research method includes three stages; production of fishery wastewater and shrimp wastewater, assembly of a dual chamber MFC bioreactor, and measurement of waste electrical energy produced. The value of electricity production with the highest average in fishery wastewater was obtained by adding electrolyte solution to the Zn/Cu electrode during 117 hours of observation were 6.86 mA with a potential difference of 1.469 V meanwhile in shrimp wastewater was obtained by adding electrolyte solution to the Al/Cu electrode were 4.38 mA with a potential difference of 1.335 V.This study can be concluded that higher electricity production is obtained from the utilization of fish wastewater using Zn/Cu electrode.

The increasing energy consumption is not directly proportional to the availability of energy. This encourages the continued development of alternative energy sources to replace fossil energy sources. In this research, a Microbial Fuel Cell (MFC) will be made as an alternative energy source that metabolism of bacteria to produce electrical energy. Microbial Fuel Cell (MFC) is made by varying the type of substrate. The type of substrate used is made of straw and borassus fruit extract. In this study, the MFC design uses a dual-chamber system consisting of an anode compartment and a cathode compartment. Analysis of the effect of substrate variations on MFC performance can be seen from the measurement data of current and voltage using a digital multimeter based on the length of time working with the addition of resistance and without resistance which is used to determine the power density value. The measurement results showed that the highest power density for straw substrate was obtained at 1 st hour measurement, which a value of 770.1 mW/m 2 for the addition of external resistance and 401.6 mW/m 2 without external resistance. Meanwhile, for the borassus fruit extract substrate, the highest power density was obtained at 29 hours of 594.1 mW/m 2 using external resistance and 364.9 mW/m 2 without external resistance. The resulting power density value is higher than previous studies so that the straw and borassus fruit extract substrate has a great potential to be used as a substrate in MFC technology.
