In this study, we developed impregnated activated carbon manufacturing process, and investigated the possibility of using coconut as a activated carbon for odor removal. Among the five collectors, KCI, NaOH, Ki, HNO3, and H2SO4, that were added to the adsorption process for the odor removal of H2S and NH3, the treatment with H2SO4 showed the best result having the adsorption quantity of 4.6 mg/g.
