Excel-ohw-utilization of human waste to make new renewable electrical energy based on mobile application in isolated village to achieve SDGS 2030 / Alifianti Shinta P.P ... [et al.]

This paper aims to describe the working principle applied to EXCEL-OHW to produce electrical energy and its efficiency level, considering that electrical energy generally comes from non-renewable fossils energy sources. Non-renewable energy utilization has drastically increased leads authors to explore new, innovative, and easy to get alternative energy. Microbial Fuel Cell (MFC) is a new alternative energy resource technology that utilizes bacterial interactions found in nature. The authors introduce new MFC innovation, mobile-based applications of EXCEL-OHW device. This device generates electrical energy from human waste as a substrate that is converted into electrical energy by electron and proton activity by bacteria in MFC technology. This device controls temperature, voltage, and can be automatically turned on and off. A graphical interface is developed to facilitate the users. This device produced 12 V DC voltage to 220 V 500 W AC voltage with 95% efficiency and minimize the electrical energy crisis and fulfill the needs of local society especially in low electrical energy source and isolated areas, such as Desa Jatisari Malang, Indonesia. This technology can be the solution to the energy crisis in order to achieve SDGs by the year 2030.
