Abstract

This study was conducted to analyze the effect of torrefaction temperature on biopellets, which are densified biomass from cassava stems, corncobs, elephant grass, bagasse, and rice straw. The torrefaction temperature factors were nontorrefied biopellet, 220 °C, 240 °C, 260 °C, and 280 °C. The experimental design used was a two-factor completely randomized design with three replications. When tested for least significant difference (LSD) on moisture content (MC) parameters, the results showed a significant difference where temperatures of 220 °C, 240 °C, and 260 °C resulted in the lowest mean MC value of 0.71%. The torrefaction temperature also showed a significant difference in the density parameter, with the highest average density produced at 220 °C and 240 °C at 0.66 N/m3. The torrefaction temperature did not show a significant difference in water absorption. However, when compared with non-torrefied biopellets, the average water absorption value showed a significant difference in the LSD test, 16.07% for non-torrefied biopellets and 13.09% for torrefied biopellets. The hydrophobicity test showed that the best torrefaction temperature for corncob biopellet was 280 °C. At this temperature, the biopellet did not experience physical and watercolor changes for 24 hours under extreme conditions (immersed in water).
