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

Penelitian ini bertujuan untuk merancang, membangun, dan menguji kinerja fermentor berbahan akrilik yang diintegrasikan dengan sistem sirkulasi pompa peristaltik untuk produksi bioetanol dari molase. Fermentor berkapasitas 7 liter dirancang menggunakan material akrilik yang transparan dan mudah difabrikasi. Sistem sirkulasi pompa peristaltik diterapkan untuk menjaga homogenitas substrat, distribusi nutrisi, dan stabilitas suhu selama proses fermentasi berlangsung. Penelitian dilakukan dengan membandingkan dua kondisi operasi, yaitu fermentasi menggunakan sirkulasi dan tanpa sirkulasi, dengan memanfaatkan ragi Saccharomyces cerevisiae. Parameter yang diamati meliputi suhu, pH, penurunan nilai Brix (kadar gula), dan densitas selama fermenasi 5 hari. Hasil penelitian menunjukkan bahwa sistem sirkulasi berhasil mempertahankan suhu yang lebih stabil pada kisaran 30–31°C serta pH yang konstan. Fermentasi dengan sirkulasi juga mempercepat fase eksponensial pertumbuhan ragi, meskipun durasinya lebih singkat akibat konsumsi gula yang lebih cepat. Penurunan nilai Brix pada sistem bersirkulasi lebih signifikan, yang mengindikasikan efisiensi konversi substrat yang lebih baik. Disimpulkan bahwa fermentor akrilik dengan sistem sirkulasi pompa peristaltik efektif dalam meningkatkan homogenitas dan stabilitas kondisi fermentasi. Untuk pengembangan selanjutnya, diperlukan penambahan sistem kontrol otomatis dan optimasi kecepatan sirkulasi guna memaksimalkan produktivitas bioethanol.
