The irradiation times was varied of 15, 20 and 25 minutes. The aims of this study is to determine the morphological characteristics, microstructure, surface area and the adsorption of activated carbon to the methylene blue, and to know the influence of microwave irradiation time variations to the quality of activated carbon as adsorbent. The results showed that the best characteristic was the activated carbon with microwave irradiation time of 15 minutes resulted microcrystallite dimension with Lc and La were 3.3494 and 1.0239 respectively, surface area of 304.82 m2 / g and the methylene blue adsorption of 82.46 mg / g. The result of methylene blue adsorption test exhibited that the time variation of microwave irradiation affected the quality of the adsorption of activated carbon that has been producedenchemical activationmicrowave irradiationactivated carbonactivated carbonsurface area and methylene bluestudent Paper Post Degree
