Abstract:
The biomass of durian peel has been transformed into charcoal on a laboratory
scale. This research aims to study the characteristics of charcoal obtained from the
carbonization process inside a furnace at a temperature of 300ºC with durations of
30, 60, and 90 minutes, namely AKD 30, AKD 60, and AKD 90. The produced
characteristics are characterized, including yield, moisture content, ash content,
charcoal surface acidity, and methylene blue adsorption, respectively. Increased the
carbonization time causes the water content and surface aciditiy to decrease, but the
ash content increased, while the adsorbed methylene blue was quite variable. AKD
30 is better charcoal than the other two charcoals, although it is still below SNI
standard 06-3730-1995.
