Abstract
The purpose of this study is to analyze the effect of particle size and the addition of sago flour on the characteristics of biopellets and to analyze the best treatment. This research was designed using a Randomized Block Design (RBD) with particle size factors (60, 80, 100 mesh) and the addition of adhesive (0, 10, 20%) with 3 repetitions. The research results were analyzed using two way ANOVA with SPSS 26 software and the multiple attributes method. Based on the analysis results, the particle size factor significantly affected all parameters, while the adhesive addition factor showed a significant effect on the parameters of density, ash content, calorific value and yield. The interaction between factors showed a significant effect on the parameters of density, moisture content, ash content, calorific value and yield. The results on the parameters of density and water content comply with SNI 8675:2018. In the parameters of ash content and fixed carbon the results obtained do not meet SNI 8675:2018. The levels of volatile matter and calorific value show results that comply with SNI 8675:2018 in several treatments. From the calculation results, it was obtained that the best treatment is the A2P3 treatment with a density value of 1.04 gr/cm3- water content 5.15%- ash content 11.33%- calorific value 3911 cal/gr- volatile matter 80.48%- fixed carbon 8.19%- yield 82.73%- silica content 442.86 ppm- chlorine content 13.53%- and 9.32% sulfur content.
