It aims to keep the liquid temperature in accordance with the desired temperature. One way to control the temperature of liquid is by using the principle of heat exchanger. The input of the plant is a thermistor sensor with the type NTC (Negative Temperature Coefficient). And the output is the servo valve connected to the output of microcontroller. Monitoring of the temperature control system at the plant is designed using Supervisory Control and Data Acquisition (SCADA). The PID control system can be applied as a temperature control using LabVIEW software as a data acquisition tool for reading temperature sensors and controlling the temperature. The PID control system can open the valve automatically by giving set point and setting value of Kp, Ki, and Kd. System stability control is a very important issue. The existence of a control system with feedback allows system stability to be achieved despite interference with the valve control system that affects temperature stability using PID controls in LabVIEW. Testing system by PID control using Kp = 1,500; Ki = 0,050; and Kd = 1,000 can give an optimal response to mini plant in this temperature process.idTeknik ElektroTeknik ElektronikaThermistorLabVIEWPIDThesis
