Pembuatan Biobriket dari Limbah Nilam dan Sekam Padi dengan Variasi Perekat Sagu

Abstract

The increasing global energy demand and the depletion of fossil fuel reserves have driven the search for renewable energy alternatives. Biomass-based biobriquettes offer a promising solution, particularly through the utilization of agricultural waste. This study aims to analyze the effect of sago binder variations (5%, 8%, 10%, 12%, and 14%) on the quality of biobriquettes made from a 50:50 mixture of nilam distillation waste and rice husk. Quality parameters tested include moisture content, ash content, volatile matter, and combustion rate, referring to SNI 01-6235-2000 standards. The results showed that increasing sago binder content from 5% to 14% caused an increase in moisture content (7.84% to 8.86%) and volatile matter (29.04% to 36.87%), while ash content decreased significantly (44.46% to 31.85%). The 12% binder variation produced the lowest combustion rate (0.089 g/min) with the highest durability. The 14% variation achieved the highest combustion temperature (469.0°C). All variations met SNI moisture content standards (<8%) except the 14% variation. The 12% sago binder composition is recommended as the optimal formulation for producing biobriquettes with balanced quality characteristics.
