Activated carbon product sales increases recently and thus various raw materials are required to be converted into active carbon. The aim of this research was to produce active carbon from chocoa skin which fulfilled SNI 06-3730-1995 and to study its kinetical adsorption in methy orange solution. Initially chocoa skin was dried, carbonized, grinded and sifted in a siever with 60 mesh. The charcoal was then activated in nitric acid solution with concentration of 0.6N for 24 hours, filtered out the particles, neutralized with aquadest and finally dried in the oven. The active carbon products were analyzed for water content, ash content, flying substance, carbon content and adsorptivity in iod solution. Active carbon from chocoa skin was also tested its adsorptivity in methyl orange solution with various times reaction. The optimum times reaction found was applied to adsorp methyl orange solution, kinetical isotherm adsorption and its capacity were finally determined. This research showed that activated carbon from chocoa skin fulfilled SNI 06-3730-1995 with 0.92% water content, 5.82% ash content, 25.4% flying substance, 68.76% carbon content and 752.18 mg/g adsorptivity in iod solution. The kinetical reaction of chocoa skin active carbon for adsorbing methyl orange solution followed both Freundlich and Langmuir isotherm equations with maximum capacity of 0.3 mg/g.
