Waste Recycle

The accumulation of untreated organic waste poses serious challenges, such as foul odors, health risks, and environmental degradation. To tackle these issues sustainably, Universitas Negeri Yogyakarta (UNY) has developed a community service program led by a team from the Department of Physics Education, Faculty of Mathematics and Natural Sciences (FMIPA). The initiative utilizes nanotechnology—specifically carbon-based nanomaterials—to transform organic waste into solid and liquid plant supplements, aiming to create a zero-waste community within a circular economy framework.

Plastic waste is not only difficult to decompose or biodegrade, plastic waste that is eaten by animals such as fish will eventually be consumed by us in the form of microplastics. This is certainly dangerous both for the environment and for ourselves. Departing from this fact, English for Holidays (EFH) UNY, which this year has the theme "Green Champion", introduced a new agenda entitled Recycling Workshop.

Five Universitas Negeri Yogyakarta(UNY) students have developed an innovative balance bike made from jute fiber. The bike serves to train cycling balance for early childhood.

The five students who made the balance bike include Rokhmad Syarifuddin (Mechanical Engineering Education), Alvy Zalyaputra Hermawan (Manufacturing Engineering), Dani Nurdiansyah (Manufacturing Engineering), Priesca Rahmanita (Management) and Desinta Auliya Arsa (Management). During the development process, the student team received guidance from Dr. Mujiono from the Faculty of Engineering UNY.

The Faculty of Language, Arts and Culture of Yogyakarta State University organized a social service outing for FBSB UNY International Students at Parangkusumo Beach. With the title "Beach Clean Up", this activity is a social service of beach cleaning, eco-bricking workshops and literacy-based fun activities with children around the beach. This activity involved international students taking credit transfer, bachelor and master programs at UNY. Forty-five international students participated in this activity.

Corn (Zea Mays L) is a plantation crop that thrives in Indonesia and can be harvested 2-3 times a year. The corn harvest period is the most awaited because farmers benefit from their crops. However, most of the corn is sold a whole. The corn cobs are only burned and even thrown away as waste. The problem is that corncob waste is easily decomposed and causes an unpleasant odor. This problem has prompted Ade Kurniawan, a student of craft education at UNY, to process corncob waste into handicraft products that are sustainable, eco-friendly, and encourage zero waste implementation.

The trend of growing fruit in pots or tabulampot is rising in Indonesia. Tambulampot cultivation has many benefits. With proper care, this method can generate greater profits, a high success rate, bear fruit out of season, be easy to move, and be developed in various fields. To support tabulampot care, a group of Universitas Negeri Yogyakarta(UNY) students consist of Irfan Aldi Fitrian and Annisa Kusumawati, Ahmad Sauki Al Zamani, and Shibghotulloh Umar Rosyadi made an environment  friendly fertilizer .
