Universitas Negeri Yogyakarta (UNY) students Tannaya Viratama Anjani, Fatya Alifah Zahra and Andre Amaral Zein Ulhaq, through the course Sustainable Development Education, recently carried out a reforestation and outreach program titled “Forest Restoration for Increasing Biodiversity” in Desa Kalitengkek, Kecamatan Gebang, Kabupaten Purworejo, Central Java.

Students from the Community Service Program (KKN) of Universitas Negeri Yogyakarta (UNY), based in Mijil Village, Giritengah, Borobudur, Magelang, have developed a simple yet impactful innovation for rural waste management by building a Rocket Stove. This stove uses a vertical draft technology that enables faster, cleaner, and low-smoke burning of domestic waste.

The innovation addresses the persistent challenge of household waste in rural areas, especially the accumulation of light organic and inorganic waste.

The Bachelor of Applied Marketing Management Study Program of the Faculty of Vocational Studies at UNY carried out a socialisation and real-action programme in the form of training in the making of eco-enzyme and eco-brick at SMP Negeri 1 Pengasih, Kulon Progo, recently.

This activity was attended by 30 students of class VII A of SMP Negeri 1 Pengasih, under the guidance of three UNY Vocational Faculty students. This cross-generational collaboration aims to instil awareness early about the importance of waste management based on the zero-waste principle.

Three students from UNY have created an eco-friendly innovation to help farmers control pests effectively without relying on chemical pesticides.

Through the 2025 Student Entrepreneurship Development Program (P2MW) of the Ministry of Higher Education, Science and Technology, the team—consisting of Ihsan Muchlis Amirudin, Afwa Naela Fauzia, and Rose Pita Nur Afifah—developed a device called the Light Trap Insect (LTI). The LTI is a solar-powered automatic pest trap that supports sustainable agriculture.

In an effort to create sustainable agriculture while maintaining environmental cleanliness, a workshop on fermenting livestock waste into organic fertiliser was held by the KKNM 24036 UNY team in Kampung Kajor Kulon, Selopamioro, Imogiri, Bantul. The activity featured a knowledgeable speaker, Abdul Rohman, an alumnus of the Integrated Organic Manure/Management (IOM) training who has applied organic fertiliser fermentation technology from cow manure since 2010.

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.

A team of students from Universitas Negeri Yogyakarta (UNY) has once again made a mark in the creative industry with their product Herbascent, a natural incense made from coconut shell fibre and gemor wood that not only delivers a soothing aroma but also functions as a natural insecticide for local-cultural ceremonial use.

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). This activity took place in Warungboto Village, Yogyakarta City, involving the Pendidikan Kesejahteraan Keluarga (PKK) mothers of RT 31/RW 08 as the main partners.

The PPK Ormawa BEM FMIPA UNY team conducted a workshop for the community of Prawatan Village, Jogonalan District, Klaten Regency, focusing on catfish farming using an IoT-based integrated biofloc-hydroponic system. The event featured Ahmad Ardan Ardiyanto, owner of Dewaponik and a nationally recognized hydroponic practitioner and innovator, as the main speaker.

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.

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.
