    Orange peel based activated carbon by microwave assisted potassium hydroxide chemical activation has succesfully been made. Pre-carbonized of activated carbon was conducted for 1 hour at temperature of 150˚C and followed by chemical activation using KOH with variation of molarity of 2 M, 3 M, and 4 M. The microwave pyrolisis was carried out using output power of 630 Watt for 15 minutes. The molarity of KOH was influenced by of the physical properties of activated carbon. Higher of output of activator concentration shows bigger of carbon content produced. The data of energi dispersive X-ray show the activated carbon of KJ4M has the highest of carbon content of 66,55%
