dc.description.abstractKetapang (Terminallia catappa) fruit shell belong to an organic waste which is a source of carbon compounds derived from cellulose, hemicellulose and lignin. This study utilized ketapang fruit shell waste in the environment Riau University campus to be converted into ashes. Ash was obtained by calcined at a temperature of 700 °C (CBK-700) and 800 °C (CBK-800) for 1 hour. Furthermore, ash was used as an biosorbent of methylene blue in following parameters variation; contact time (15, 30, 45 and 60 minutes), dosage of adsorbent (0,5; 1; 2 and 3 g) and initial concentration of adsorbate (10, 15, 20, 25, 30, 40 and 50 ppm). Result of the research showed that adsorption of methylene blue by ketapang fruit shell occured in optimum condition of contact time 15 minutes, dosage of adsorbent 0,5 g and initial concentration of adsorbat 50 ppm. Ketapang fruit shell ash was given the adsorption capacity value against methylene blue were 5,1030 mg g-1 for CBK-700 and 5,0280 mg g-1 for CBK-800. Difference of calcination temperature wasn’t give a large difference against asdorption capacity of methylene blue.en_US
