Indonesian coal-based activated carbon was manufactured with steam-reaction method. Also effects of carbonization temperature and steam amount on the process yield and quality of the product were investigated at the activation temperature of $900^{\circ}C$. The rotary kiln type furnace was used for both carbonization and activation and the optimum operation conditions were carbonization temperature of $700^{\circ}C$, steam amount of 2.7g steam/g char and activation temperature of $900^{\circ}C$. At this condition, the iodine value of activated carbon was 1,010 mg/g. Methylene Blue Adsorption Number was 230mg/g and B.E.T. surface area was $1,020m^2/g$ with the hardness about 97.
