Abstract
Sago dregs (SG) are the by-product of sago stems which contains cellulose components and has the potential as a biomass fuel source. Thus, this condition encourages the conversion of SG biomass waste into bio-coke as an alternative solid fuel by interacting with the bio-oil resulting from the pyrolysis of SG biomass. This study aims to determine the effect of variations in the alloy between bio-oil and bio-char SG as raw material for making bio-coke with bio-oil compositions of 10, 20, 30, 40 and 50% (w/v) using the pyrolysis method at a temperature of 500 to 600 \(^o\) C. The characterization results showed that the bio-coke content of the bio-oil alloy had a moisture content of \(2.99 \pm 0.9% \) , volatile matter of \(38.45\pm 6%\), ash content of \(13.91 \pm 0.6%\), and fixed carbon of \(44.65 \pm 6.4%\) . The calorific value of bio-coke increases with the composition of bio-oil, with a maximum calorific value of 13,565.854 kcal/kg. Thus, bio-oil interacting with SG bio-coke is a potential strategy for waste biomass management in alternative fuel applications.
