Students participating in the Community Service Program (KKN) from Universitas Negeri Yogyakarta (UNY) carried out a community empowerment activity through a demonstration on managing organic waste using biopore absorption holes and gallon-based composters in Padukuhan Degolan, Kalurahan Bumirejo, Kapanewon Lendah, Kulon Progo Regency.

The activity was intended to increase villagers’ awareness of the importance of environmentally friendly organic household waste management and to support efforts to improve groundwater absorption capacity through biopore systems.

The program aligns with the achievement of Sustainable Development Goals (SDGs), especially SDG 12 on Responsible Consumption and Production and SDG 13 on Climate Action.

During the activity, students Lulu Dyah Nugrahaeni and Nasywa Humaira explained the basic concept of biopore holes and their environmental benefits. They described biopore as a type of absorption hole filled with organic waste like vegetable scraps, fruit peels, and dry leaves, which can naturally decompose into compost and help reduce surface water pooling.

In addition, the presenters demonstrated three types of organic waste management media: Biopore using PVC pipe Biopore using recycled gallon containers Composters made from used gallons All of these tools were introduced as simple, low-cost technologies that residents can make independently using waste materials found around the home.

This effort also contributes to SDG 11 on Sustainable Cities and Communities by promoting community-based environmental management.

According to the KKN team leader, Ahmad Farhan Fadhila, the activity reflects the students’ contribution to supporting sustainable development at the local level. He explained that beyond reducing household waste volume, the biopore practice also helps maintain environmental balance and groundwater availability.

Throughout the demonstration, villagers showed high enthusiasm—asking questions about biopore maintenance, what waste materials could be used, and how to recognize compost that is ready to use. The students also provided guidance on how to care for the biopore and composter so they won’t produce bad odors and can be used over the long term, as part of ongoing sustainable environmental education.

The demonstration was carried out by the KKN-R 20 Degolan team, consisting of: Ahmad Farhan Fadhila, Irsyad Sabiluddin, Isna Lutvia Sri Harnani, Laire Anindya Isnaini Azzahra, Lulu Dyah Nugrahaeni, Nabila Alya Fatiha, Nabila Velda Azzahra, Nasywa Humaira and Nayla Shahira.

Through this activity, UNY KKN students hope to foster collective awareness in the community to manage waste independently and sustainably—while making a real contribution toward SDG achievement at the village level.
