Abstract


The aims of this study are to determine the influence of percentage of potassium hydroxide (KOH) and to
the adsorption of methylene blue of the activated carbon. Activated carbon was prepared from fibers of
empty fruit bunches of oil palm (fibers of EFB) pre-carbonized at 280℃ for 4 hours. Chemical activation
was conducted to the sample for 25 hours with weight percentage of KOH of 25%, 50%, and 75%, and
subsequently the sample was then irradiated by microwave with the out put power of 720 Watt for 15
minutes. The highest methylene blue of 87,731 mg/g was obtained from sample with percentage of KOH
of 75%. The higest stack height (Lc) of 2.897 nm was also resulted from the methylen blue.
