Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui kombinasi terbaik pembuatan biobriket dari campuran cangkang biji karet dan serbuk gergaji kayu dengan penambahan perekat tepung tapioka. Hal ini didasari oleh kurangnya pemanfaatan limbah di area sekitar perkebunan karet, sementara penggunaan bakar bakar fosil terus naik. Kombinasi komposisi yang digunakan pada biobriket adalah 80% cangkang biji karet : 20 % serbuk gergaji kayu, 75 % cangkang biji karet : 25 % serbuk gergaji kayu, 70 % cangkang biji karet : 30% serbuk gergaji kayu, dengan penambahan perekat sebesar 10 % dari berat massa adonan. Parameter yang diukur dalam penentuan kualitas biobriket adalah kadar air, kadar abu, nilai kalor, volaile matter, fixed carbon, laju pembakaran dan efisiensi bahan bakar. Data yang diperoleh disajikan dalam bentuk tabel, diagram, dan perhitungan. Hasil penelitian ini menunjukkan hasil nilai kalor tertinggi didapat pada komposisi 80 : 20 (Sampel A) yang mendapat nilai kalor 6717 cal/gram. Kadar air terendah pada penelitian ini berada pada komposisi sampel A sebesar 9.00%. Kadar fixed carbon tertinggi didapatkan pada kmposisi 70: 30 (Sampel C) yaitu 42.88%. kadar volatile matter terendah didapatkan pada sampel B yaitu 40.08%. kadar abu terendah didapatkan pada sampel B yaitu 4.28%. Hasil penelitian ini menunjukkan bahwa semakin banyak komposisi bahan baku cangkang biji karet maka nilai kalor semakin tinggi, terbukti pada kombinasi komposisi pada sampel A, untuk efisiensi dan laju pembakaran biobriket sampel C terbukti unggul dibandingkan 2 sampel lainnya. Kata Kunci : Biobriket, Cangkang Biji Karet, Serbuk Gergaji Kayu, Nilai Kalor, Analisa Proksimat, Laju Pembakaran, Sifat Pembakaran, Efisiensi Bahan Bakar ABSTRACT This research aims to determine the best combination for making biobriquettes from a mixture of rubber seed shells and wood sawdust with the addition of tapioca flour adhesive. This is based on the lack of waste utilization in areas around rubber plantations, while the use of fossil fuels continues to increase. The composition combination used in biobriquettes is 80% rubber seed shells: 20% wood sawdust, 75% rubber seed shells: 25% wood sawdust, 70% rubber seed shells: 30% wood sawdust, with the addition of 10% adhesive. weight of dough mass. The parameters measured in determining the quality of biobriquettes are water content, ash content, heating value, volatile matter, fixed carbon, combustion rate and fuel efficiency. The data obtained is presented in the form of tables, diagrams and calculations. The results of this research show that the highest calorific value was obtained in the composition 80: 20 (Sample A) which received a calorific value of 6717 cal/gram. The lowest water content in this study was in sample A composition of 9.00%. The highest fixed carbon content was obtained in composition 70: 30 (Sample C), namely 42.88%. The lowest volatile matter content was found in sample B, namely 40.08%. The lowest ash content was obtained in sample B, namely 4.28%. The results of this research show that the greater the composition of the rubber seed shell raw material, the higher the calorific value, as evidenced by the combination of compositions in sample A, for the efficiency and burning rate of sample C the biobriquettes were proven to be superior to the other 2 samples. Keywords: Biobriquettes, Rubber Seed Shells, Wood Sawdust, Calorific Value, Proximate Analysis, Burning Rate, Combustion Properties, Fuel Efficiency
