Charcoal is a porous solid material which is resulted from combustion of material that containing the carbon element (C).Charcoalcanbeusedasrawmaterialsinthemanufactureof batteries,charcoalbriquettes,andcharcoalcompost,can also be further processed in to activated charcoal. This study aims to manufacturing activated carbon from Kemiri Sunan shellwasteasrawmaterials,determiningit'soptimumconditionsandphysico-chemicalproperties. The results showed that Kemiri Sunan shell can be used as raw material for activated charcoal with the following qualities: adsorb capacity of iodine solution 138.46-768.31 mg/g, adsorb capacity of benzene 2.99-21.37%, and adsorb capacity of methylene blue 18.239-260.237 mg/g. The optimum conditions of manufacturing of activated charcoal is produced at temperature of 850°C that are soaked in a solution of 10% H3PO4 with steam activation time for 90 minutes results adsorb capacity of iodine and methylene blue which meets the technical requirements of activated charcoalintheIndonesianstandard(SNI)number 06-3730-1995.
