Five UNY students developed an innovation in oral health care through the Student Creativity Entrepreneurship Programme (PKM-K) 2025. The product, called Covatab, is a tooth-cleanser tablet made from coconut-shell charcoal and rice-husk silica, free from sulfates, effective in removing plaque, safe for use, and environmentally friendly.

The spirit and curiosity coloured an environmentally-friendly agriculture training organised by students of the Community Service Programme (KKN) of UNY. Equipped with knowledge and concern for the environment, the students educated residents of Dadapan, Sidoluhur, Godean, Sleman to produce liquid fertiliser and natural pesticide from simple materials around their homes.

Universitas Negeri Yogyakarta (UNY) reaffirmed its commitment to building an environmentally-friendly campus by organizing a Workshop on Processing and Dilution of Eco-Enzyme on Saturday (19 July 2025) at the Basic Chemistry Laboratory, Faculty of Mathematics and Natural Sciences (FMIPA), UNY.

Four students from the Faculty of Mathematics and Natural Sciences (FMIPA) at UNY have succeeded in utilizing cassava peel waste to create a magnetite-activated carbon nanoparticle composite that functions as an adsorbent for chromium (Cr) ions in the leather industry’s wastewater. The team, called “Adsorben Singkong,” consists of Ankita Cahya Muti (Chemistry, 2022), Oktavia Kusuma (Mathematics, 2022), Puput Intan Pratiwi (Mathematics Education, 2022), and Khansa Amalia Rahmah (Biology, 2023).

Students of the Bachelor’s program in Culinary Education (S1 Pendidikan Tata Boga), Faculty of Engineering, UNY, once again demonstrated their creativity at the “Culinary Innovation Festival 2025”, held at Garden Level 1 of Sleman City Hall.

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.

A group of students from Universitas Negeri Yogyakarta (UNY) has found a creative way to help solve the problem of batik wastewater pollution by using discarded orange peels as an eco-friendly bioadsorbent. Led by Jalu Bahtiar Baharudin from the Biology program, the team extracted pectin from Citrus sinensis peels and found it to be highly effective in binding harmful dye residues typically found in batik industry waste.
