KARAKTERISASI ARANG AKTIF KULIT DURIAN (Durio Zibethinus Murr) YANG DISINTESIS SECARA KOMBINASI AKTIVASI DI DALAM KILN DRUM MICROWAVE

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.
