ABSTRACT

Bamboo contains high cellulose so it can be used as basic ingredient for making activated charcoal. Activated charcoal has multifunctional, as an adsorbent and antibacterial. This study aims to determine the potencial inhibition of bamboo charcoal unactivation and activated with ZnCl2 and the minimum inhibitory concentration (MIC) of activated bamboo charcoal ZnCl2 against Escherichia coli and Staphylococcus aureus. The activated charcoal produced was characterized according to the National Standard Indonesia regarding technically activated charcoal. The functional groups possessed were analyzed by Infrared Spectroscopy. The surface reactivity was estimated by Iodine adsorption and the active site by acid-base titration. The results showed that unactivated charcoal did not has antibacterial properties. The best antibacterial properties occurred at a concentration of solution ZnCl2 35% (w/v) with an inhibitory power of 10 mm against Escherichia coli and Staphylococcus aureus. The MIC value of activated charcoal was 95% (w/v) for Escherichia coli and Staphylococcus aureus respectively, with an inhibitory power of 7 mm and 7.5 mm.
