Research  on activated carbon production from dirty coal with chemical process has been done. This research was Investigated the effect of concentration of phospharic acid as the activator on characteristics  the product Activated carbon was produced by activation of dirty cool for 2 hours at 800 0C. Chemical activation was done using phosphoric acid solution at various concentration:  15 %, 20%, 25 %, and 30 % for 24 hours and 0 % as control. The best quality of activated carbon was obtained from activated carbon using 25 % phosphoric acid. At this condition  the produced  activated carbon has choracteristics  of 1.87 % moisture content,  13,41 % ash content and adsorptive  capacity  of iodium  804.56  mg/g. This adsorptive capacity fulfill of the requirements of National  Standard  of  Indonesia for Technical  Activated Carbon (SNI 06-3730-1995).
