Abstract

Biogas merupakan salah satu sumber energi alternatif yang dihasilkan dari proses fermentasi bahan organik secara anaerob untuk menghasilkan gas yang sebagian besar berupa gas metana (CH4) dan karbondioksida (CO2). Pada kandungan biogas terdapat gas pengotor yaitu CO2. Salah satu cara untuk meningkatkan kualitas biogas agar kandungan gas metana pada biogas meningkat dan menurunkan gas-gas pengotor seperti CO2 yaitu dilakukan proses pemurnian biogas menggunakan purifier yang berisi adsorben yaitu arang aktif dan silika gel. Tujuan penelitian adalah untuk mengetahui proses peningkatan kualitas biogas melalui proses pemurnian dan mengetahui kualitas biogas setelah melalui proses pemurnian menggunakan Down-Up Purifier dengan arang aktif dan silika gel sebagai adsorben. Hasil penelitian menunjukkan bahwa penggunaan adsorben arang aktif dan silika gel dapat menurunkan kandungan gas CO2 sebesar 78,2% dan kandungan gas CH4 sebesar 68,4% dengan waktu pemurnian optimal yaitu 30 menit.

Abstract

Biobriquette is an alternative fuel that is environmentally friendly because it uses organic materials. Wastes that can be used for biomass briquettes include agricultural wastes such as coconut shells and rice husks. Briquettes are also made using certain adhesives as a hardener in briquettes. The purpose of this study was to determine the effect of molasses adhesive content and drying time on the quality of biobriquette manufacture, with this study useful for reducing energy use to be used as fuel, reducing coconut shell and rice husk waste, and also knowing the molasses adhesive content and drying time required. appropriate for the manufacture of biobriquettes. In this study, there were 2 factorials, namely the amount of molasses adhesive content of 30%, 40%, 50% and drying time of 5 hours, 6 hours, 7 hours with a combination of both treatments. Testing the characteristics of biobriquettes includes the value of water content, ash content, volatile matter, density, and combustion rate. Parameters used as reference are in accordance with Indonesian briquette quality standards. From the results of the research, it is known that the molasses adhesive content and the appropriate drying time are K1W3 samples with an adhesive content of 30% and a drying time of 7 hours because of the lowest water content value and also produces good and durable briquettes when burning briquettes.

Abstract

Biogas purification is an effort to increase the calorific value of biogas. The CO2 content in biogas causes the calorific value of the biogas to decrease, so it is necessary purification is carried out to reduce CO2 gas levels and to increase gas levels CH4. The research objectives were 1)To determine the effect of refining time on quality biogas, 2)Knowing the effect of gas flow rate on purification on the quality of the biogas produced, and 3) Determine the duration of purification and the best gas flow rate for purification biogas. The research method used a completely randomized design (CRD) with two factors namely the purification time (15, 20, and 25 minutes) and the gas flow rate (2,4, and 6 L/min) respectively repeated three times, then analyzed the data using the ANOVA test and followed by the DMRT test. The results showed a C/N ratio of 19.46%, the average substrate temperature was 30.23°C, the average pH was 7.3, the total solid was 7.217, and volatile solid of 79.459. ANOVA test results show that there is a significant effect on methane content, while carbon dioxide content has no effect real. The best purification time and biogas flow rate were 25 minutes (178,018.01 ppm) and 6 L/minute (474,744.3 ppm) because it produces the highest methane content, while for the content carbon dioxide at a purification time of 20 minutes (1201.62 ppm) and a gas flow rate of 4 L/minute (52,012.4 ppm) due to produces the lowest levels of carbon dioxide
