Virgin Coconut Oil (VCO) has health benefits because it contains compounds that are good for the body. This study aims to control the temperature in the coconut milk extraction chamber into VCO to maintain the stability of these fatty acids. With a setpoint temperature of 34°C, PI and PID controllers are used whose parameters are determined through the Ziegler-Nichols and Cohen-Coon tuning methods. This research was modeled and simulated in MATLAB. The results show that the PID controller with the Cohen-Coon method provides a better system response compared to Ziegler-Nichols, with a settling time of 8757.4 seconds, an overshoot of 9.6518%, and a steady state error of 0%. Meanwhile, the PI controller with the Cohen-Coon method has a settling time of 8901.7 seconds, an overshoot of 7.1398%, and a steady state error of 0%. Tests show that the system can achieve overshoot below 3 and steady-state error below 1, according to the expected specifications
