Therefore, the authors provide new innovation in the form of the EXCEL-OHW device. This device is a tool that can generate electrical energy that utilizes human waste as a substrate that will be converted into electrical energy by the activity of electrons and protons by bacteria in MFC technology. By using this EXCEL-OHW technology, it is hoped that it can overcome the electrical energy crisis, especially in isolated village, for example in Jatisari Village, Malang, one of the regions in Indonesia, where there are a lot of human waste resource and has not had electricity yet. The implementation of this technology can achieve the Sustainable Development Goals (SDGs) number 7, that clean and affordable energy can ensure access to affordable, reliable, and affordable energy. (Novisari, 2011). Bacteria in organic medium convert organic material into electrical energy. The property of bacteria that can degrade the organic medium (enrichment media) in MFC produces electron and proton ions. These ions produce the difference in electric potential so that energy can be generated.
EXCEL-OHW-Utilization of Human Waste to Make New and Renewable Electrical Energy Based on Mobile Applications in Isolated Villages to Achieve SDGs 2030
Short Description:
Energy availability is a crucial requirement for human life. In the recent era, the demand for alternative energy, especially electrical energy, has increased drastically. Cited from Indonesia’s Agency for Study and Application of Technology (BPPT) in 2017, the demand for electricity in the industrial and household sectors was 37% with a total of 2,584 TWh. Interestingly, the number of people who have not had access to electricity has even reached 87.69 million people (BPPT, 2017). One of the technologies that can be a new alternative energy source is the Microbial Fuel Cell (MFC). Unfortunately, the application and development of Microbial Fuel Cell technology in Indonesia are still minimal. Based on the results of previous research, the difference with this writing lies in the Mobile Application system and the fuel used.
