Started from anxiety when he realized the high number of rivers in Indonesia, Mohammad Amin Abil, a Mechanical Engineering student at the University of Muhammadiyah Malang (UMM), succeeded in designing a machine called EH1 (Electrolysis of Hydrogen 1). This tool breaks down river water into industrial oxygen and hydrogen that can be used in health and transportation.

"Indonesia has a lot of rivers. I wonder, what if these rivers could be utilized for a Indonesia in the future," he said.
Involving two of his friends, Evita Leninda Fahriza Ayuni and Shahrul Asy'ari, he used the river water flow that rotates an Archimedes turbine to generate electricity. This electricity is used to electrolyze, breaking down hydrogen and oxygen, then put into a gas trap and stored in the storage.
"As a result, the hydrogen can be used as a zero-emission fuel that is very environmentally friendly. Meanwhile, the oxygen can be used to support health services such as the oxygen in hospitals," he said.
Full of confidence, Amin believes the innovation that won the Bronze Medal at the Thailand Inventor's Day 2023, Trade and Exhibition Center (BITEC) last February can be a strategic breakthrough. In the middle of various environmentally friendly fuels issues, the breakthrough carried by the student from Palu, Central Sulawesi, can compete nicely.

"Currently, various advanced countries, ranging from Europe to our neighbor Singapore, have used many hydrogen-fueled vehicles, both trains and cars. Hopefully soon, Indonesia will also not be left behind. We must start thinking forward that Indonesia can be much better in the future, including in terms of technology, "he stated.
Several lecturers also guided Amin and his friends' innovation. There are Dini Kurniawati, ST. MT, Dr. Ir. Achmad Fauzan Soegiharto, MT, and Andinusa Rahmandhika, S.T., M.Eng. These three lecturers provided a lot of feedback so that the tool could be made optimally.
Amin's system is truly environmentally friendly from the beginning to the end of the process. There is Grey Hydrogen, where hydrogen production still produces waste (high carbon emission), and blue hydrogen (low carbon emission), which still uses coal. But something different was given by Amin and his team's breakthrough, which entered the level of green hydrogen (zero emission).
"All of our processes are natural and certainly do not damage nature. Even the use of the arcimedes turbine is also done with the sustainability of the surrounding environment. Fish can even live when passing through it," Amin added.
Finally, Amin hopes that the potential of the Indonesian people can get more attention. Thus, the dream of an advanced Indonesia will soon become a reality, especially in technology. "Indonesia has many talented young people who are able to lead to an advanced Indonesia in the 4.0 era. These good ideas must be accommodated and continuously developed for a better life in the future," he said. (put/sil/wil)
