Abstract: Experimental design was applied in the optimization of crude oil adsorption from saline waste water using raw bagasse. The application of response surface methodology (RSM) was presented with temperature, salinity of water, pH, adsorbent dose, and initial oil content as factors. A quadratic model could be used to approximate the mathematical relationship of crude oil removal on the five significant independent variables. Predicted values and experimental values are found to be in good agreement with R2 of 97.44%. The result of optimization shows that the maximum crude oil removal is equal to 67.38% under the optimal condition of temperature of 46.53 °C, salinity of 37.2 g/L, pH of 3, adsorbent dose of 9 g/L and initial oil content of 300×10-6.
