Abstract

One alternative energy that can be used as a substitute for fuel oil and gas is biomass energy such as briquettes. This study aims to determine the amount of heat, moisture content and ash content of briquettes made using hazelnut shells and glutinous rice adhesives that vary in adhesive concentration and particle size. This study used a complete randomised design (CRD) with variations in glutinous rice concentration of 20%, 30%, and 40% while the particle sizes used were 12 mesh and 24 mesh. The results showed that the adhesive concentration did not significantly affect the test parameters while the particle size affected the moisture content, ash content and calorific value of the briquettes. The highest calorific value was obtained by using 24 mesh particle size with 20% adhesive concentration with a calorific value of 5321 cal/g while the 12 mesh particle size produced the highest calorific value of 4704 cal/g at 20% adhesive concentration. The lowest moisture content value was obtained by using 24 mesh particle size with 20% adhesive concentration with a moisture content value of 6.9% while the 12 mesh particle size produced the lowest moisture content value at 20% adhesive concentration with a value of 7.4%. The lowest ash content value was obtained by using 24 mesh particle size with 30% adhesive concentration with an ash content value of 4.99% while the 12 mesh particle size produced an ash content value of 5.82%. The use of 12 mesh particle size is not in accordance with SNI standards because the heating value produced is still below 5000 cal/gr while the use of 24 mesh particle size is in accordance with SNI standards for all test parameters.

Abstract

Abstrak Limbah sering dihasilkan dari proses produksi industri dan domestik, dan sering kali tidak memiliki nilai ekonomis. Di daerah dengan jagung sebagai komoditas utama, limbah jagung seperti kulit dan tongkol sering diabaikan. Di Kabupaten Lombok Barat, jagung merupakan komoditas penting dengan hasil panen mencapai 77.304 ton pada tahun 2023. Namun, limbah jagung belum dimanfaatkan secara optimal. Program pengabdian masyarakat ini bertujuan untuk mengajarkan warga Desa Mesanggok mengolah limbah bonggol jagung menjadi briket, sebagai alternatif bahan bakar yang ramah lingkungan. Metode yang digunakan dalam kegiatan ini ialah sosialisasi yang meliputi ceramah, diskusi, dan pemutaran video, diikuti dengan pretest dan posttest untuk mengevaluasi peningkatan pengetahuan peserta. Hasil kegiatan menunjukkan peningkatan pengetahuan peserta dari 43% menjadi 92%, dengan hasil uji statistik menggunakan uji paired sample T test yang signifikan. Sosialisasi ini tidak hanya meningkatkan pengetahuan tetapi juga membuka wawasan peserta mengenai peluang usaha baru melalui produksi briket dari limbah jagung, mendukung program zero waste Pemerintah Provinsi Nusa Tenggara Barat, serta berkontribusi pada upaya peningkatan kesejahteraan ekonomi masyarakat setempat. Kata kunci: bonggol jagung; briket; energi; limbah biomassa Abstract Waste is often generated from industrial and domestic production processes, and often has no economic value. In areas where maize is the main commodity, maize waste such as husks and cobs are often neglected. In West Lombok Regency, maize is an important commodity with a yield of 77,304 tonnes in 2023. However, corn waste has not been optimally utilised. This community service programme aims to teach residents of Mesanggok Village to process corncob waste into briquettes, as an environmentally friendly alternative fuel. The method used in this activity is socialisation which includes lectures, discussions, and video screenings, followed by pretests and posttests to evaluate the increase in participants' knowledge. The results of the activity showed an increase in participants' knowledge from 43% to 92%, with statistical test results using a significant paired sample T test. This socialisation not only increased knowledge but also opened participants' insights into new business opportunities through the production of briquettes from corn waste, supporting the West Nusa Tenggara Provincial Government's zero waste programme, and contributing to efforts to improve the economic welfare of the local community. Keywords: biomass waste; briquettes; energy; maize cobs.
