ANALISIS KARAKTERISTIK BRIKET CAMPURAN CANGKANG KEMIRI DAN LIMBAH ROKOK

Analysis of Briquettes Mixture of Candlenut Shells and Cigarette Waste

Krisis energi global mendorong pencarian alternatif bahan bakar berkelanjutan. Biomassa, terutama limbah pertanian dan kehutanan menjadi fokus utama dalam pengembangan energi terbarukan. Penelitian ini mengeksplorasi potensi limbah cangkang kemiri dan limbah rokok sebagai bahan baku pembuatan briket. Penelitian ini bertujuan untuk menganalisis karakteristik briket (nilai kalor, kadar air, kadar abu, zat mudah menguap, dan laju pembakaran) dari cangkang kemiri dan limbah rokok dengan tambahan perekat tepung tapioka. Variasi campuran briket dengan bahan cangkang kemiri dan limbah rokok menggunakan komposisi (1:1 ; 3:1 ; 1:3) serta menambahkan 10 gram tepung tapioka dalam 100 gram bahan baku. Karakteristik briket cangkang kemiri dan limbah rokok dengan perekat tapioka di peroleh kadar air paling rendah sebesar 6,0618% pada sampel S3 dan tertinggi sebesar 7,4365% pada sampel S2. Kemudian, kadar abu paling rendah sebesar 10,0327% pada sampel S2 dan tertinggi sebesar 12,4496% pada sampel S3, kadar zat menguap terendah sebesar 82,368% pada sampel S3 dan tertinggi sebesar 92,483% pada sampel S2. Kualitas briket arang cangkang kemiri dan limbah rokok yang terbaik dan proporsional dalam penelitian ini pada sampel S2 dengan komposisi campuran 3:1 dan penambahan perekat tapioka sebanyak 10 gram dalam 100 gram bahan baku dengan kadar air 7,4365%, kadar abu 10,0327%, kadar zat menguap 92,483%, dan nilai kalor 6781,42 cal/g. 

The global energy crisis is driving the search for alternative sustainable fuels. Biomass, especially agricultural and forestry waste, has become a primary focus in renewable energy development. This research explores the potential of candlenut shell waste and cigarette waste as raw materials for briquette production. This study aims to analyze the characteristics of briquettes (calorific value, moisture content, ash content, volatile matter, fixed carbon content, and burning rate) made from candlenut shells and cigarette waste with the addition of tapioca starch as a binder. Variations in the briquette mixture using candlenut shell and cigarette waste materials employed compositions of (1:1; 3:1; 1:3), with the addition of 10 grams of tapioca starch in 100 grams of raw materials. The characteristics of candlenut shell and cigarette waste briquettes with tapioca binder showed the lowest moisture content of 6.0618% in sample S3 and the highest of 7.4365% in sample S2. Subsequently, the lowest ash content was 10.0327% in sample S2 and the highest was 12.4496% in sample S3, the lowest volatile matter content was 82,368% in sample S3 and the highest was 92,483% in sample S2, and the lowest calorific value was 4815.01 cal/g in sample S3 and the highest was 6781.42 cal/g in sample S2. The best and most proportional quality of candlenut shell and cigarette waste charcoal briquettes in this study was found in sample S2 with a mixture composition of 3:1 and the addition of 10 grams of tapioca binder in 100 grams of raw materials, exhibiting a moisture content of 7.4365%, ash content of 10.0327%, volatile matter content of 92,483% and a calorific value of 6781.42 cal/g.
