Universitas Negeri Yogyakarta (UNY) proudly celebrated a sustainable innovation milestone as the NanoBotato team from the Faculty of Mathematics and Natural Sciences (FMIPA) won first place at the 14th UNY Science and Engineering Fair (UNYSEF) 2025. Their project turned agricultural waste—specifically potato peels—into eco-friendly nanomaterials, addressing both waste reduction and clean water challenges in a single solution.

By extracting nanoscale compounds from discarded potato skins, the team developed biodegradable nanofilters capable of removing pollutants from water without introducing harmful chemicals. This innovation not only offers an effective alternative to conventional water filtration methods, but also highlights the potential of reusing food waste in solving pressing environmental issues. Judges praised the project for its strong alignment with sustainability and circular economy principles.

Team leader Siti Nurjanah emphasized the project's environmental motivation: “Our goal was to prove that even everyday waste holds incredible value when approached with creativity and care for the planet. Potato peels, often seen as trash, became our tool for clean water.” The team’s work reflects UNY’s growing emphasis on student research that responds to real-world sustainability challenges through low-cost, locally sourced solutions.

Following their victory, the NanoBotato team is set to represent UNY in broader science and innovation competitions, carrying a message of waste transformation and environmental stewardship. Their success not only showcases FMIPA’s commitment to green innovation but also positions UNY as a leader in advancing sustainable practices through youth-led research.
