Abstract

This community service program aimed to develop rice husk-based charcoal biobriquette production technology through a carbonization process in Pasie Laweh Nagari, Lubuk Alung District. The initiative sought to address the underutilization of rice husk waste, which is abundant in the region due to its significant rice farming activities. By converting agricultural waste into eco-friendly biobriquettes, the program provided an alternative energy source while enhancing the economic value of waste for local farmers. The implementation involved training, technology transfer, and hands-on mentoring, resulting in the production of biobriquettes with a diameter of 2 cm, height of 5 cm, and a burning duration of 2--3 hours per unit. The program achieved a 95% participation rate, with active involvement from farmers, youth groups, and local MSMEs. Quantitative analysis through pre-test and post-test revealed a significant increase in participants' knowledge and skills. The average scores for understanding the concept of biobriquettes increased from 45% to 85%, carbonization techniques from 35% to 80%, understanding of economic benefits from 50% to 90%, and practical skills from 30% to 75%. Economic benefits included a 40% reduction in fuel costs for businesses and 30% savings for households. The success of the program highlights the potential of biobriquettes as a sustainable energy solution and underscores the importance of community empowerment, institutional support, and technological innovation in rural development.

Abstract

This community service program aimed to address the problem of wood dust waste in Sungai Buluh Nagari, Padang Pariaman Regency, by converting it into biobriquettes as a renewable energy source. The wood dust waste generated by local woodcrafters has not been utilized optimally and is often burned directly, causing air pollution. Through a participatory approach, this program involved technical training, technology transfer, and hands-on mentoring in biobriquette production. Quantitative analysis through pre-test and post-test of 20 participants showed a significant increase in understanding, with the "highly understood" category surging from 4.2% to 55.0%. Implementation results showed that the community successfully produced functional biobriquettes with specifications of 2 cm diameter, 3 cm height, and a burning duration of 2-3 hours per unit. Community participation reached 93%, with product utilization by satay vendors and households reporting up to 40% savings in fuel costs. This program not only successfully enhanced the economic value of waste but also established independent production groups committed to continuing the biobriquette business sustainably. Support from the village government and community enthusiasm were key success factors, while also contributing to reduced environmental pollution and energy independence at the local level.

Abstract

This community service program aimed to optimize the utilization of coconut shell waste into biobriquettes as an environmentally friendly alternative energy source in Korong Pilubang, Nagari Katapiang. The program partners included farmer groups, PKK women's groups, youth organizations (Karang Taruna), and local MSMEs. This initiative addressed the issue of abundant coconut shell waste generated from coconut farming activities, which had not been optimally utilized and often contributed to environmental pollution. Through a participatory approach, the program provided comprehensive training and direct technical assistance covering carbonization, molding, and packaging processes of biobriquettes. The implementation produced biobriquettes with specifications of 3 cm in diameter, 6 cm in height, and a burning duration of 2–3 hours per unit. Quantitative evaluation using pre-test and post-test methods revealed significant improvements in participants' understanding of biobriquette concepts (from 45% to 85%), carbonization techniques (from 35% to 80%), economic benefits (from 50% to 90%), and practical skills (from 30% to 75%). The program has also generated measurable economic impact, including fuel cost savings of up to 40% for small businesses and 30% for households. These outcomes have been sustained through the establishment of an independent production group and increased community awareness of renewable energy and sustainable waste management, supported by close collaboration with the local village government.
