Abstract

Activated carbon had successfully been made from betung bamboo (Dendrocalamus Asper) bycarbonization process for 1 hour with chemical activation using pottasium hydroxide (KOH) with themass ratio of the carbon powder with KOH i.e. 1:0, 1:1, 1:2 and 2:1. In order to activate the carbon,the activation was help by microwave irradiation with the power of 630 Watt for 20 minutes. Thepurpose of this research is to characterize activated carbon using X-ray diffraction (XRD), FourirerTransform Infrared Spectroscopy (FTIR) and absorption of methylene blue. The data of X-raydiffraction pattern indicated that all of the activated carbon were in a semi-crystalline form, with theXRD peaks observed at angel of diffraction (2θ) of 21.268o and 41.014o with oriented of (002) and(100) respectively. The highest value of layer (Lc) is resulted from the ratio 1:1 as high as 21.495 nmand this data supported by the highestabsorption of methylene blue at ratio 1:1 as high as 99.327mg/g. Characterization of FTIR showed that the activated carbon had the function of cluster –OH, CHand C=C. Overall the calculated and analyzed results showed that the variation of KOHconcentration influences the qualities of the activated carbon.
