Abstract
Biobriquettes are a biomass fuel with high calorific value. This study aims to determine the optimal conditions on the particle size of husk charcoal and the addition of vinasse waste as an independent variable using Response Surface Methodology with the Central Composite Design (CCD) method on Design Expert 13 software. The manufacturing process of rice husk charcoal briquettes is carried out by a carbonization process which is then mashed and sieved according to particle size of 20, 30, 40, 50, and 60 mesh. Then, the sample is mixed with tapioca starch as adhesive with the ratio of charcoal and adhesive 8:1 as well as vinasse waste in volumes of 3, 6, 9, and 12 mL. The resulting briquette samples were tested in the form of water content, ash content, and calorific value tests. The optimum conditions that have a significant effect on the response variable are the combination of particle size variables of 35.152 mesh and the volume of vinasse waste of 6.049 mL. The moisture content obtained was 6.696%, ash content was 5.450%, and the calorific value was 5003.399 cal/gr with a desirability value of 0.927 in the quadratic model.
