Another achievement was made by Yogyakarta State University students. In this event, there were five students who participated in this competition, they were students from different study programs. This team was chaired by Muhammad Ikhsan Ardi Hansyah from the Applied Undergraduate Electrical Engineering Study Program, then with members Hilal Fahrul Hamam from the Applied Undergraduate Electrical Engineering Study Program, Ersa Ivadany Hidayat from the Applied Undergraduate Electrical Engineering Study Program, Fitria Alsya Yasmin from the Electronics Engineering Study Program, and the last is Chayyu Zalena Hawie from the German Language Education Study Program. These students managed to win two awards at once, namely the Gold Medal in the Category of Technology and the Macedonian Special Award in the World Youth Invention and Innovation Award (WYIIA) event which was held online.

WYIIA itself is an event that aims to present ideas and innovations in various categories that have been provided in the provisions. This competition is held by the Indonesia Young Scientist Association (IYSA) and in collaboration with several parties, one of which is the Malaysia Innovation Invention Creativity Association. WYIIA was attended by 450 teams from 35 countries in the world.

As the team leader in this event, Muhammad Ikhsan Ardi Hansyah or who is familiarly called Hansyah feels very proud to be able to get this extraordinary award. In this competition, Hansyah and his team made a device that can detect pH levels in rivers that are polluted by tofu waste. With this tool, it will be able to detect the existing pH levels and find out whether the environment is safe for the organisms around or not. When the pH condition is considered unsafe for the environment, the servo will work and will stabilize it with acid or alkaline content and will also add good nutrition for biota and the environment.

Before designing and making the tool, Hansyah and his team made observations on rivers polluted by tofu waste in Gunung Kidul Regency, D.I Yogyakarta. Hansyah and his team saw that several rivers had been polluted and so they came up with the idea to make these tools. This tool is also if calculated in terms of cost, it is cheaper than pH meter tools on the market.

Being able to get two awards at the same time is a matter of pride for Hansyah and the team. Hansyah and his team hope to participate in a similar competition with the hope of support from various parties, especially from UNY. In the future, Hansyah and his team will also invite other students to join in similar events and hope that by participating in competitions like this, UNY's name can be better known to the world and UNY can be more advanced than before (RBD).
