Students of Universitas Negeri Yogyakarta (UNY) have developed an innovation in the livestock sector by conducting practical training on the production of environmentally friendly fermented animal feed at the Campus Animal Husbandry Laboratory. This activity serves as an applied learning platform to introduce students to natural-based and resource-efficient feed processing technologies.

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.

Universitas Negeri Yogyakarta (UNY) reaffirmed its commitment to environmental sustainability by planting mangrove trees along the coastal area of Pasir Mendit Beach in Jangkaran, Temon, Kulon Progo, on Sunday, October 12, 2025.

This initiative is part of UNY's ongoing efforts to support the United Nations Sustainable Development Goals (SDGs), particularly SDG 13 (Climate Action), SDG 14 (Life Below Water), and SDG 15 (Life on Land), as well as to contribute to the UI GreenMetric World University Ranking, which assesses universities' commitment to sustainability.

Waste management has become an urgent issue in many major cities, including Yogyakarta. To help address this problem, Universitas Negeri Yogyakarta (UNY) through the Dharma Wanita Persatuan (DWP) has taken part by organizing a creative recycling program.

The Program Penguatan Kapasitas Organisasi Kemahasiswaan (PPK Ormawa) PKM Center FMIPA Universitas Negeri Yogyakarta (UNY) conducted a workshop on transforming organic waste into Liquid Organic Fertilizer (POC) at the Balai Desa Barukan, Kecamatan Manisrenggo, Klaten. The event, held recently, was attended by approximately 50 participants, including students, student organization representatives, accompanying lecturers, and farmer groups from Desa Barukan.

Students of the Faculty of Mathematics and Natural Sciences at UNY, through the Student Creativity Program (PKM), conducted a research titled “Gel Nano-Hydroxyapatite (n-HAp) Based on Tiger Snail Shells: Biocomposite Innovation Kurma Ajwa / Siwak / Propolis for Enamel Remineralisation of Teeth”. They developed this innovation in dental health by utilising waste tiger snail shells (cangkang keong macan) as a base material for the production of nano-hydroxyapatite gel (n-HAp).

In order to increase community awareness of the importance of organic waste management, a team of students on the Community Service Program (KKN) from UNY carried out an educational activity in Dusun Druju, Desa Margodadi. This activity took place at the home of Mrs Umi (RT 04), who fully supported the implementation of this program.

A team of UNY lecturers conducted an accompaniment programme in which 40 members of the women’s empowerment group (PKK) in Sembuhan Kidul participated. The goal of this activity was to increase the knowledge and skills of the community— especially housewives— in utilising household and garden organic waste so that it is not simply discarded, but processed into liquid organic fertilizer which can be useful for family farming as well as becoming an economically valuable product.

Students at UNY once again demonstrated their role in delivering real solutions for society. Through the Student Creativity Programme – Application of Science & Technology (PKM-PI), a student team introduced “SmartCleaner: Solar-Powered Cleaning System & Ammonia Monitoring”, to assist the farmers’ group “Kelompok Tani Ngudi Makmur” in Gunung Manuk Village, Patuk District, Gunungkidul.

The innovation emerged from concerns over a classic issue faced by cattle farmers: the barn is difficult to clean regularly and high levels of ammonia gas pose danger to the livestock.

UNY continues to demonstrate its commitment to supporting sustainable campus initiatives through the use of renewable energy. One concrete step is the installation of solar-cell panels in the corridor connecting the Faculty of Education UNY (FIP).
