Abstract: Tabah bamboo is a rare bamboo that only grows in some regions of Bali. Bamboo is one of the carbon-rich plants worthy of being processed as a raw material for activated charcoal. This study aimed to determine the potential of Tabah bamboo charcoal inactivated and activated by ZnCl2 as an adsorbent for methylene blue. The research was started by making bamboo charcoal labeled Bo and activated charcoal, BA. The optimized adsorption parameters cover contact time, adsorbent mass, pH solution, initial concentration, and temperature for the best performance. The adsorbent characterization includes functional groups, morphology, surface area, and pore volume. The results showed the contact time of 90 minutes, a mass of adsorbent 0.2 g, and a pH of 10, for the Bo and BA charcoals. Adsorption isotherm models for both charcoals tend to follow Langmuir. The adsorption capacities were 70.22 mg/g and 79.24 mg/g for Bo and BA respectively. Characterization results showed that Bo and BA have similar functional groups had a carbon content of 85.79% and 96.96%, and a surface area of 0.1879 m2/g and 5.1037 m2/g, respectively.
