Producing activated carbon from coconut shell with work test to metal (Pb2) h conducted Activation by using pyrolisis that flowing gas Pyrolisis temperature variated from 350C to 500C and residence time 05, I, I,S and 2 hours The adsorption activated carbon yield is 42,S% in activated carbon that has pyrollisis 350 C d residence time 0,S hour The lowest yield is 32,22% that has pyrolisis at 500C and residence time 2 hours. The result of water content analysis 011%. The adsorption test of ebon and capacity of adsorption where down by using methylene blue and timbal. The highest adsorption of methylene bile is 141288 mg/g and that was activated on 500C and residence time hours The highest capacity of adsorption (Ku/iv of with carbon is 100,00 mg/g and that w activated o 450CM residence time I hour The isotherm model of adsorption of timbal from the experiment result was follow the isotherm model of Langmuir. Key word : activated carbon, adsorption, pirolisis, coconut shell.
