      Abstract
      Biomassa merupakan sumber energi alternatif terbarukan yang layak diperhitungkan, karena memiliki cadangan melimpah dan sifat ramah lingkungan. Penelitian ini bertujuan untuk menentukan proporsi optimal limbah tempurung kelapa, sekam padi, serta serbuk gergaji sebagai bahan baku pembuatan briket bioarang dan mengkaji pengaruh terhadap sifat fisika dan kimianya. Secara umum terdapat standar persentase bahan baku briket bioarang yang sering digunakan untuk tempurung kelapa 60–90%, sekam padi 20–50%, dan serbuk gergaji 30–70%. Campuran bioarang paling optimal yang didapatkan dalam penelitian ini adalah tempurung kelapa 70%, sekam padi 10%, dan serbuk gergaji 20% (formula 2). Hasil pengujian yang didapatkan sebesar, densitas 0,73 g/cm3, indeks kehancuran 6,80%, laju pembakaran 3,89 g/menit, kadar air 7,12%, kadar abu 7,20%, kadar zat terbang 51,34%, kadar karbon terikat 34,34%, nilai kalor 5216,11 kal/g, dan kadar karbon pada uji CHNSO sebesar 57,40%. Briket yang dihasilkan memiliki kualitas fisik yang tidak mudah hancur dan nilai kalor yang cukup tinggi.
       
      Biomass is a viable renewable alternative energy source to consider, as it has abundant reserves and environmentally friendly properties. This study aims to determine the optimal proportion of coconut shell waste, rice husk, and sawdust as raw materials for making bio-charcoal briquettes and to examine their effects on physical and chemical properties. Generally, the standard percentages of raw materials frequently used for bio-charcoal briquettes are 60–90% for coconut shells, 20–50% for rice husks, and 30–70% for sawdust. The most optimal bio-charcoal mixture obtained in this study consists of 70% coconut shell, 10% rice husk, and 20% sawdust (formula 2). The test results obtained were: a density of 0,73 g/cm³, shatter index of 6,80%, burning rate of 3,89 g/min, moisture content of 7,12%, ash content of 7,20%, volatile matter content of 51,34%, fixed carbon content of 34,34%, calorific value of 5216,11 cal/g, and carbon content from the CHNSO elemental analysis of 57,40%. The resulting briquettes possess physical qualities that do not break easily and a considerably high calorific value.
