Abstract
Ketapang seed shell biomass (CBK) waste is part of the ketapang fruit which undergoes
a very slow degradation process due to its high lignin content. Lignin compounds are
classified as chemical components that can be converted into activated charcoal. The
purpose of this study was to determine the effect of carbonization temperature in
converting the shells of kepatang into activated charcoal. Activated charcoal is made by
carbonization of CBK at temperature variations of 400°C, 500°C and 600°C for 30
minutes and is labeled ACBK-400, ACBK-500 and ACBK-600. All ACBK were
characterized by gravimetric and X-ray diffraction (XRD) methods. The results showed
that the highest yield of charcoal was at ACBK-400 of 33.03%, the lowest moisture
content was in ACBK-500 of 5.90% and the lowest ash content was in ACBK-400 of
0.78%. XRD analysis showed that ACBK has an amorphous structure with the largest
Lc/La ratio at ACBK-600.
