  • The purpose of this research to prove that sawdust can be used as raw material for making activated carbon. The sawdust contain chemical components such as cellulose, hemisolulosa, lignin and extractive substances that can be activated carbon (Gufta, 1998). The process of making activated carbon through the stages of dehydration, carbonization, activation, and analysys. The process of making activated carbon known that waste sawdust will work optimum if used NaOH solution, particel size 200 mesh for 30 hours. Activated carbon is applied to the liquid waste processing equipment laboratory by entering into the adsorption column at a height of 15 cm with a weight of 1.24 kg of activated carbon and activated carbon size of 200 mesh. While the adsorption process, conducted observations of the color and odor as well as analysis of pH, turbidity, salinity, conductivity, Total Dissolved Solid (TDS), Dissolved Oxygen (DO), BOD (Biological Oxygen Demand) and COD (Chemical Oxygen Demand). The results showed that the adsorption process with the color dan odor is transparant with decrease analysis of 3,89% pH, 80,83% turbidity, 3,82% salinity, 3,60% conductivity, 3,55% TDS, 0% DO, 81,39% BOD, and 4,72% COD.
