Abstract
Berdasarkan data Badan Geologi Kementerian Energi dan Sumber Daya Mineral (ESDM) 2020, Indonesia memiliki sumber daya batu bara yang melimpah, tetapi penggunaannya menyebabkan emisi CO2, NOx, SO2, dan materi partikulat yang merugikan lingkungan. Sebagai alternatif ramah lingkungan, biomassa seperti bonggol jagung semakin diakui sebagai sumber energi yang potensial. Biomassa ini dapat diolah menjadi biopelet, bahan bakar yang lebih bersih. Namun, produksi biopelet memerlukan perhatian terhadap biomassa, proses produksi, serta parameter suhu dan tekanan. Faktor seperti ukuran dan rasio bahan aditif dapat memengaruhi kualitas biopelet. Masalah kerak juga dapat diatasi dengan zeolit dan NaOH. Penelitian ini menggunakan metode Rancangan Acak Kelompok (RAK) dengan faktor ukuran mesh (2 level; 20 dan 40 mesh) dan rasio bonggol jagung:zeolit:NaOH (4 level - 100:0:0; 98,4:0,1:1,5; 97,7:0,3:1,5; dan 97:0,5:2,5) serta parameter kadar air, kadar abu, total solid, volatile solid, fixed carbon, dan volatile matter. Perlakuan terbaik ditentukan dengan menggunakan metode Zeleny. Hasil penelitian menunjukkan bahwa ukuran biomassa (20 dan 40 mesh) dan rasio bonggol jagung:zeolit:NaOH signifikan memengaruhi parameter kadar abu, volatile solid, fixed carbon, dan volatile matter. Meskipun penambahan NaOH dan variasi ukuran mesh meningkatkan kadar abu dan mengurangi nilai volatile solid dan fixed carbon, kombinasi keduanya tidak memberikan signifikansi terhadap kualitas biopelet. Hasil terbaik dengan penambahan zeolit dan NaOH dicapai pada formulasi A2Z1 rasio (98,4:0,1:1,5)% dan ukuran mesh 20, menunjukkan rata-rata nilai setiap parameter yang memuaskan, termasuk kadar air (6,86%), kadar abu (1,47%), total solid (93,14%), volatile solid (91,77%), fixed carbon (20,68%), dan volatile matter (77,85%). Hal tersebut menunjukkan biomassa layak digunakan dalam pembuatan biopelet.
English Abstract
Based on the data from the Geological Agency of the Ministry of Energy and Mineral Resources (ESDM) in 2020, Indonesia possesses abundant coal resources. However, their utilization leads to emissions of CO2, NOx, SO2, and particulate matter, which are harmful to the environment. As an environmentally friendly alternative, biomass such as corn cobs is increasingly recognized as a potential energy source. This biomass can be processed into bio-pellets, a cleaner fuel. However, bio-pellet production requires attention to biomass selection, production processes, as well as temperature and pressure parameters. Factors such as size and additive ratio can influence the quality of bio-pellets. Crust issues can also be addressed with zeolite and NaOH. This study employs a Randomized Complete Block Design (RCBD) with factors including mesh size (2 levels; 20 and 40 mesh) and corn cob:zeolite:NaOH ratio (4 levels - 100:0:0; 98.4:0.1:1.5; 97.7:0.3:1.5; and 97:0.5:2.5) along with parameters of moisture content, ash content, total solid, volatile solid, fixed carbon, and volatile matter. The best treatment is determined using the Zeleny method. Results indicate that biomass size (20 and 40 mesh) and corn cob:zeolite:NaOH ratio significantly affect parameters such as ash content, volatile solid, fixed carbon, and volatile matter. Although the addition of NaOH and variation in mesh size increase ash content and reduce volatile solid and fixed carbon values, the combination of both does not significantly affect bio-pellet quality. The best results with the addition of zeolite and NaOH are achieved with formulation A2Z1 at a ratio of (98.4:0.1:1.5)% and mesh size 20, showing satisfactory average values for each parameter, including moisture content (6.86%), ash content (1.47%), total solid (93.14%), volatile solid (91.77%), fixed carbon (20.68%), and volatile matter (77.85%). This indicates that biomass is suitable for use in bio-pellet production.
