Abstract:
Durian peel activated charcoal was successfully synthesized using drum kiln
carbonization with physical activation using 300 W microwave heating for 8 minutes
(AAKD8), 10 minutes (AAKD10) and 12 minutes (AAKD12). This research aims to
study the characteristics of durian skin charcoal and charcoal that is physically activated
with microwaves from durian skin biomass. The quality of activated charcoal is
determined based on Indonesian national standards (SNI 06-3730-1995). AKD
characterization results for water content, ash content, methylene blue adsorption
capacity were 2.19%; 12.46%; and 47.1673 mg/g. Based on variations in microwave
activation time, the results showed that the lowest water content was in the AAKD12
sample at 0.20%, the lowest ash content was in the AAKD8 sample at 10.29%, and the
methylene blue adsorption capacity was in the AAKD8 sample at 49.4541 mg/g.
Variations in activation time using microwaves affect the characteristics of activated
charcoal. Based on the quality standards for durian peel activated charcoal, it meets SNI
standard No. 06-3730-1995. Based on the samples that have been characterized, it shows
that AAKD8 is the best sample because it has all the maximum test characteristics.
