Some research proved that activated carbon could be made from organic materials or anorganic material with very high carbon content. The exist research of activated carbon from coconut shell, bagasse, and saw dust. In fact, there’s a lot of material can be used as raw material, like cassava skin. At this research, done with activator type variable ( HCL, NAOH, and CaCl2), activation period ( 24 hours, 22 hours, 20 hours and 18 hours ), and particle size (- 115 mesh, - 60+115 mesh, - 32+60 mesh, and - 16+32 mesh). This research analyzed is volatile matter, water content, and iodium adsorption. The best activator at making of this activated carbon is HCl. The best activation period is 24 hours and the best particle size is - 115 mesh, In industrial process, activated carbon is used for deodorized, adsorbs taste, eliminate colours and organic contaminant. Testing for active carbon in this research was based on activated carbon quality standard from Standar Industri Indonesia No. 0258-88.
