ANALISIS KUALITAS BIOBRIKET KARBONISASI TEMPURUNG KELAPA DAN KULIT SINGKONG DENGAN PEREKAT TEPUNG SINGKONG

Abstract

One of the steps that can be taken to overcome fossil fuel sources is the use of renewable energy sources, especially renewable energy sources. The transfer of energy sources from fuel oil to renewable energy sources is expected to reduce the level of dependence on petroleum. Utilization of agricultural waste, plantation waste or industrial waste is an alternative fuel substitute by converting it into biobriquettes. Coconut shells and cassava peels are agricultural wastes that can be used as materials for making biobriquettes and their availability is quite abundant in Indonesia. This study aims to determine the characteristics of coconut shell and cassava peel carbonized biobriquettes, determine the effect of material composition and adhesive percentage on the quality of coconut shell and cassava peel carbonized biobriquettes. This study used a completely randomized design (CRD) with a combination of 9 experimental variations. The experiment was repeated 4 times so that 36 experimental units were obtained. The treatment factors used in this study were the percentage of adhesive (P0 = 3% adhesive, P1 = 5% adhesive, P2 = 7% adhesive) and material composition (K0 = 80% coconut shell carbonized powder and 20% cassava peel carbonized powder, (K1 = 75% coconut shell carbonized powder and 25% cassava peel carbonized powder, (K2 = 70% coconut shell carbonized powder and 30% cassava peel carbonized powder). The variables observed in this study were water content, ash content, volatile matter content, evaporated, bound carbon content, calorific value, density, and compressive strength. The data obtained were analyzed using the F test and DMRT test at 5% level. The results showed the characteristics of carbonized biobriquettes of cassava peel and coconut shell using cassava flour adhesive, namely water content ( 6.71-7.75%), ash content (4.16-4.63%), volatile matter content (2.01-2.18%), bound carbon content (85.53-87.02% ), calorific value (6709.29-8142.82cal/g), density (0.57-0.74 g/cm3), and compressive strength (3.36-7.66 kg/cm2). The composition of the material and the percentage of adhesive have a significant effect on the moisture content, ash content, volatile matter content, bound carbon content, calorific value, density, and compressive strength.
