Agricultural waste generated from rural farming activities has significant potential as a renewable energy resource; however, its utilization remains limited due to inadequate knowledge and technical skills among communities. This community service activity aimed to strengthen the capacity of rural communities in transforming agricultural waste into charcoal briquettes as an alternative renewable energy source. The activity was conducted in Nogoro Oro Village, Patuk District, Gunungkidul Regency, Special Region of Yogyakarta, Indonesia, involving 25 participants consisting of cocoa farmers, farmer group members, farmer pioneers, agricultural extension officers, and village representatives. The program was implemented through a participatory empowerment approach involving preparation, socialization, theoretical explanation, hands-on training, charcoal briquette production, utilization demonstration, and evaluation. The training introduced participants to agricultural waste utilization, biomass carbonization, charcoal briquette processing, and the application of briquettes as alternative solid fuels. The results showed an improvement in participants’ knowledge from 60% before training to 85% after training. Participants were also able to produce agricultural waste-based charcoal briquettes through a simple production process, resulting in approximately 5 kg of dried briquette products. The community response toward the introduced technology was positive, indicated by high participation, technology understanding, perceived relevance, and interest in future briquette production. This activity demonstrates that appropriate technology-based community empowerment can support the conversion of agricultural waste into valuable renewable energy products while promoting sustainable waste management and circular economy practices in rural areas.
