Abstract:
Bamboo betung (Dendrocalamus asper) is one of the plant types found in Buruk Bakul village where located in Bukit Batu Bengkalis. The aim of this study was to analyze of the potential of charcoal from bamboo betung as adsorben. Charcoal was made by doing carbonization of bamboo betung at 500oC for an hour and then re-carbonized for 60 and 30 minutes. The results indicated that charcoal from 60 minutes re-carbonization of bamboo betung contained 0.70% water, 5.69% ash and 80.18 m2/g surface area. The charcoal from 60 minutes re-carbonization proses was used for further adsorption analysis of borehole water in batch system. The results indicated that all tested parameters (pH, temperature, color, DHL, TSS, TDS, copper and sulphate) were below the minimum threshold required by PERMENKES No.416/MENKES/PER/IX/1990.
