A student team at Universitas Negeri Yogyakarta (UNY) has presented a unique innovation in safeguarding water quality by utilizing banana peel waste as the main material. Through a study titled “Green Synthesis Cu₂O/TiO₂ Nanotube Arrays (TNA) for Detection of Pb²⁺ Ions in Water”, the team succeeded in developing an environmentally-friendly technology capable of detecting the presence of the heavy metal lead (Pb²⁺) more efficiently and sustainably.

The Community Service Team (PkM) of the Faculty of Mathematics and Natural Sciences (FMIPA) at Universitas Negeri Yogyakarta (UNY) conducted training and assistance on processing household organic waste into liquid plant supplements based on carbon nanomaterials (CNMs).

The workshop covered topics such as biofloc pond management, hydroponic maintenance techniques, and strategies for integrating both systems to support food security and enhance the village's economy.

Universitas Negeri Yogyakarta (UNY) continues to strengthen its commitment to creating a green and sustainable campus. Through the Directorate of Infrastructure, Facilities, and Assets, UNY has installed a new Smart Water Station (SWS) at the Faculty of Law (FH) UNY. This facility serves as an environmentally friendly drinking water refill station that supports the reduction of single-use plastic bottle consumption on campus.

The Community Service Team (PKM) from UNY held a training and practical session for the residents of Dusun Jomboran, Minggir, Sleman, on Friday, 15 August 2025. The session, which took place in a local resident’s house and was attended by 30 participants, aimed to provide education and skills to effectively and environmentally manage household organic waste.

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.

As part of its commitment to environmental management and sustainability, Universitas Negeri Yogyakarta (UNY) has appointed dedicated teams to compile Environmental Management and Monitoring Implementation Reports for its campuses. These efforts are formalized through Rector’s Decrees for the year 2024: Karangmalang Campus (Decrees No. 178.2/UN34/I/2024 and No.
