Abstract
Durian skin waste (Durio zibethinus) which contains quite high levels of
cellulose, lignin and carbon can be used as raw material for active carbon. In this
research, the characteristics of active carbon synthesized from In this research, the
characteristics of activated carbon synthesized from durian peel waste were
studied using a furnace at a temperature of 700oC for 2 hours to obtain KADF and
microwave at a power of 750 W for 75 seconds to obtain KADM. The
characteristics of active carbon determined are basicity and surface functional
groups. The results of the characterization show that the surface alkalinity of
KADM activated carbon is higher than that of KADF. Likewise, the -O-H
functional group in KADF is lost, while the other functional groups (C-H, C=C,
C-O) show a lower percent transmittance compared to KADM activated carbon.
These results show that physical activation using a microwave at 750 W for 75
seconds is better than using a furnace at 700 oC for 2 hours..
