Abstract
Biopelet adalah salah satu bahan bakar terbarukan yang berasal dari biomassa. Biopelet dapat digunakan sebagai bahan bakar boiler pada industri dan pemanas ruangan. Beberapa biomassa yang dapat dimanfaatkan menjadi biopelet adalah serbuk kayu akasia dan batang singkong. Serbuk kayu akasia banyak ditemui di usaha mebel, tempat gergajian kayu dan kerajinan kayu. Serbuk kayu akasia hanya dibuang, dibakar, atau dijual dengan harga sangat murah. Limbah batang singkong juga kurang mendapat perhatian oleh petani, dari sekitar 1 ha perkebunan singkong dapat ditanam hingga 15.625 batang singkong, sementara petani biasanya akan menggunakan sekitar 20 persen batang singkong untuk kebutuhan penanaman kembali, sementara 80 persen sisanya hanya menjadi limbah yang tidak dimanfaatkan (Dewi, 2019). Penelitian ini menggunakan metode Rancangan Acak Kelompok (RAK) model linear dengan dua faktor, faktor pertama adalah persentase campuran serbuk kayu akasia (SKA) dan Limbah Batang Singkong (LBS) dan faktor kedua adalah perbedaan ukuran ayakan. Faktor A terdiri dari 5 taraf 100% SKA, 75% SKA dan 25% LBS, 50% SKA dan 50% LBS, 25% SKA dan 75% LBS, serta 100% LBS), faktor B terdiri dari 4 taraf (tidak diayak, 20 mesh, 40 mesh dan 60 mesh). Pengujian sampel dilakukan menggunakan parameter kadar air, kadar abu, densitas, laju pembakaran dan nilai kalor. Dari penelitian ini diperoleh hasil, yaitu kadar air terendah pada perlakuan C1A3 sebesar 8,31%, kadar abu terendah pada perlakuan C1A0, C1A1, C1A2, C1A2, C2A2 dan C2A3 sebesar 1,67%, nilai densitas tertinggi pada perlakuan C1A3 sebesar 0,45 gr/cm3, laju pembakaran tercepat pada perlakuan C1A1 sebesar 0,088 gram/menit, dan nilai kalor tertinggi pada campuran 50% SKA dan 50% LBS sebesar 4445,00704 cal/gram. Variasi campuran berpengaruh nyata terhadap kadar air, kadar abu, densitas, laju pembakaran dan nilai kalor. Perbedaan ukuran mesh berpengaruh nyata terhadap kadar air, kadar abu, densitas, dan laju pembakaran.
English Abstract
Biopellet is one of the renewable fuels derived from biomass. Biopellet can be used as boiler fuel in industry and space heating. Some of the biomass that can be used as biopellet is acacia wood powder and cassava stems. Acacia wood powder is commonly found in the furniture business, wood sawmills and wood crafts. Acacia sawdust is simply thrown away, burned, or sold at very low prices. The waste of cassava stems is also less attention given by farmers, from about 1 ha of cassava plantations up to 15,625 cassava stems can be planted, while farmers will usually use about 20 percent of cassava stems for replanting needs, while the remaining 80 percent is just unused waste (Dewi , 2019). This study used a linear randomized block design (RAK) method with two factors, the first factor was the percentage of mixture of acacia sawdust (SKA) and Cassava Stem Waste (LBS) and the second factor was the difference in sieve size. Factor A consists of 5 levels (100% SKA, 75% SKA and 25% LBS, 50% SKA and 50% LBS, 25% SKA and 75% LBS, and 100% LBS), factor B consists of 4 levels (not sifted , 20 mesh, 40 mesh and 60 mesh). Sample testing was carried out using the parameters of water content, ash content, density, combustion rate and calorific value. From this study, the results obtained, namely the lowest water content in the C1A3 treatment of 8.31%, the lowest ash content in the C1A0, C1A1, C1A2, C1A2, C2A2 and C2A3 treatments of 1.67%, the highest density value in the C1A3 treatment of 0, 44586 gr/cm3, the fastest burning rate in the C1A1 treatment was 0.08775 gram/minute, and the highest heating value in a mixture of 50% SKA and 50% LBS was 4445,00704 cal/gram. The variation of the mixture has a significant effect on the moisture content, ash content, density, combustion rate and calorific value. Differences in mesh size have a significant effect on moisture content, ash content, density, and combustion rate.
