Activated carbon has been successfully made from wood Eucalyptus pellita with different carbonization time. Eucalyptus pellita wood carbonized conventionally using canned, cut and sieved to the size of 1-2 mm. Carbon with different carbonization time has been activated using KOH in ratio mass : KOH 2:1 and irradiated using microwave for 20 minutes at 630 watts. The research result showed carbon…
