ABSTRACT Activated carbon made of coconut shell charcoal from boiler machine waste in desiccated coconut factory has been studied. For the first stage, coconut shell charcoal was dehydrated in electric oven afterward carbonated in electric furnace at 400 o C for 1 hour and then chemically activated by soaking the charcoal in Na 2 CO 3 5% (w/w) solutions for 24 hours. For the next stage charcoal was physically activated at 600 o C for 1 hour, milled and filtered by 28 mesh sieve. Activated carbon was then examined and the result complied with Indonesian National Standard (SNI) Quality Requirement of Activated Carbon No. 06-3730-1995, loss of ignition at 950 o C = 18%, water content =4.4%, ash content = 2.6% and adsorption of I 2 = 825 mg/g. Effectivity of activated carbon to adsorb Cd, Cu and Pb metals also tested.  As the result, we obtained that adsorbtion effectivity of activated carbon proportional with time (15, 30, 45 and 60 minutes) and inversely proportional with concentration of metals (5, 10, 20, 40 ppm).
