Bangli — Undergraduate students participating in the Thematic Community Service Program (KKN-T) Period VI of Udayana University in 2025, from the Agroecotechnology Undergraduate Program, Faculty of Agriculture, organized a workshop on biochar production using coffee husk waste in Lembean Village, Kintamani District, Bangli Regency, on Thursday, 18 December 2025.

The activity involved village officials of Lembean, members of the Subak Abian Lumbung Sari farmer group, assisted households, and local community members. The workshop aimed to provide education and practical skills on converting agricultural waste, particularly coffee husks, into biochar as a sustainable input for environmentally friendly farming practices.

The workshop material was delivered by Putu Oki Bimantara, S.P., M.Agr., a lecturer of the Agroecotechnology Undergraduate Program, Faculty of Agriculture, Udayana University, who also serves as the Field Supervising Lecturer for the KKN-T program. In his presentation entitled “Utilization of Coffee Husk Waste as Biochar to Improve Soil pH”, he explained that biochar can enhance soil chemical properties, particularly by increasing acidic soil pH, thereby supporting improved growth and productivity of coffee plants.

Representatives of the village administration expressed their appreciation for the contribution of Agroecotechnology students and lecturers from Udayana University in organizing an educational activity that is highly relevant to the needs of local farmers.

In addition to the theoretical session, the workshop included hands-on practice in biochar production, covering the drying of coffee husks, controlled combustion under limited oxygen conditions, and proper application techniques in agricultural fields. Participants demonstrated strong enthusiasm through active engagement in discussions and field practices.

Through this workshop, students and lecturers of the Agroecotechnology Undergraduate Program at Udayana University hope that the community of Lembean Village will be able to independently manage coffee husk waste, improve soil quality, and promote the adoption of sustainable and environmentally friendly agricultural practices.
