This study aimed to optimize the neutralization process of sardine oil. Central composite design of RSM was used as experimental design with two variables, NaOH concentration and neutralization temperature.  The result showed that quadratic regression model for yield and PV as response and linear regression model for FFA as response were suitable to explain the interaction between variables and responses. The optimum operation condition was reached by a treatment of NaOH 18 °Be at 40 ℃. Its desirability value was 0.534. The validation of optimum point resulted 85.90% of oil yield, 90.77% FFA reduction, and 36.92% PV reduction.
