Abstract: In this study, we want to see the effect of chemical activation on coconut shell charcoal to absorb laundry waste. Chemical activation uses HCL and H2SO4 with concentrations of 10%, 15% and 20% for each activator. The research was conducted by activating coconut shell charcoal in chemistry and physics. Chemical activation is done by soaking the charcoal into HCl and H2SO4 solutions for 24 hours after which physical activation is carried out by oven-burning charcoal at a temperature of 200 oC for 60 minutes. Activated coconut shell charcoal mixed with laundry waste and then stirred using a magnetic stirrer for 60 minutes for the absorption process. After that the laundry waste from the absorption results tested by pH, TDS, Viscosity, clarity and detergent content. The results showed that for all absorption, the best clarity was obtained at a concentration of 20% in HCl and H2SO4 solutions of (37 and 57) Lux. The best impurity particle absorption was indicated by a concentration of 15% with pH values ??of HCl (7.4) and H2SO4 (6.7), viscosity of HCl (110.93) N / m3 and H2SO4 (116.53) N / m³. While the maximum TDS value is indicated by the concentrations of HCl 10% (321) ppm and H2SO4 in concentration of 15% (309) ppm. While the results for the best detergent content are shown by 15% HCl concentration which is 0.4248 mg / L.
