Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh variasi komposisi sekam padi (ASP) dan arang tempurung kelapa (ATK) terhadap karakteristik biobriket, seperti kadar air, kadar abu, densitas, nilai kalor, dan laju pembakaran. Variasi komposisi bahan adalah 0%-90% ASP dan 90%-0% ATK, dengan perekat tepung tapioka sebesar 10%. Hasil penelitian menunjukkan bahwa nilai kalor tertinggi (9.034 kkal/g) ditemukan pada komposisi 45% ASP + 45% ATK, sementara laju pembakaran tertinggi (0,7254 g/menit) pada komposisi 90% ASP + 0% ATK. Biobriket dengan komposisi optimal (45% ASP + 45% ATK) memiliki keseimbangan antara nilai kalor tinggi dan pembakaran stabil. Semua sampel memenuhi standar SNI untuk kadar air (maksimal 8%) dan nilai kalor (minimal 5000 kkal/g). Penelitian ini menunjukkan potensi biobriket berbasis limbah pertanian sebagai bahan bakar alternatif yang berkelanjutan.

The Effect of Rice Husk and Coconut Shell Charcoal Composition Variations on the Calorific Value and Combustion Rate of Biobriquettes
Abstract
This study aims to evaluate the effect of rice husk (ASP) and coconut shell charcoal (ATK) composition variations on biobriquette characteristics, including moisture content, ash content, density, calorific value, and combustion rate. The composition variations ranged from 0%-90% ASP and 90%-0% ATK, with 10% tapioca starch as a binder. Results indicated the highest calorific value (9.034 kkal/g) at 45% ASP + 45% ATK, while the highest combustion rate (0.7254 g/min) was observed at 90% ASP + 0% ATK. Biobriquettes with an optimal composition (45% ASP + 45% ATK) achieved a balance of high calorific value and stable combustion. All samples met the SNI standards for moisture content (maximum 8%) and calorific value (minimum 5000 kkal/g). This study highlights the potential of agricultural waste-based biobriquettes as a sustainable alternative fuel source.
