Students of Universitas Brawijaya (UB) across faculties develop a Microbial Fuel Cell device that functions to convert human waste into electricity. This research was developed in the title DELETE (Digital Fuel Cell from Human Waste): An Alternative Way to Solve Electrical Energy Crisis by Using IOT / Internet of Things to Implement The SDGs 2030.

At the 10th International Exhibition of Inventions and 3rd World Innovation and International Invention Forum 2018 which was held in Foshan, Guangzhou, China, on September 13-15 2018, this research received 3 awards at once.

Namely the Silver Medal and the International Invention Award from the Malaysian Association of Research Scientists (MARS) and the Young Innovator Award from Citizen Innovation Singapore. The competition was attended by 253 teams from 49 countries.

Naila El ’Arisie, Head of the Research Team, said that the research conducted by the team took 3 months. Inspired by research that has been conducted abroad, the team took the initiative to apply and prove directly.

“We have seen in Indonesia that no one has ever applied, so we want to prove, really can or not, then we try it also integrated with software applications,” said a student from the Industrial Engineering Department.

Besides Naila, the research involved Muhammad Khuzain (Faculty of Engineering), I Wayan Angga Jayadiyuda (Faculty of Engineering), Muhammad Syarifuddin (Faculty of Computer Science), Firdausi (Faculty of Agriculture), Rina Ervina (Faculty of Economics & Business), Tubagus Syailendra W (Faculty of Social Science & Politics), Hendra Surawijaya (Faculty of Veterinary Medicine), and supervisor lecturer Eka Maulana, ST., MT., M.Eng.

Naila explained, this tool is shaped like an acrylic chamber using PEM (Proton Exchange Membrane) assistance. Human waste functions as a substrate to generate electricity because of its electroactive bacteria content.

“For the prototype we used cow dung first. While the software application that is created serves to control the temperature, humidity, voltage, and the current produced,” explained Naila.

From the measurement, each chamber can produce 1 volt. Because of the e chamber, the device can produce 3 volts and can be increased to 22 volts using a boost converter.

“So if we want to apply it to household appliances, just keep increasing the number of chambers. In the future it is expected to be used in remote areas that have not been electrified,” she concluded (and)
