Abstract: The Process Control Systems course, newly introduced in the 2022 ATI Makassar Polytechnic curriculum, emphasizes applied control practices to strengthen students’ understanding of process regulation. This study develops a teaching module for water tank level regulation using Proportional Integral Derivative (PID) control implemented through LabVIEW and Arduino Uno. Employing a Research and Development (R&D) approach with the DEDTE framework (Define, Explore, Design, Test, Evaluate), a mini plant was designed featuring a bang-bang controller with a 220 VAC water pump as the manipulated variable and a pendulum sensor connected to a 10 kΩ potentiometer. To enable PID control, a proportional valve actuated by an MG995 servo motor was integrated. Experimental results showed the level sensor achieved 97.61% accuracy, 2.86% precision, and 99.83% correlation with a regression model Y = 8.1025X – 12.488. The servo-controlled valve test indicated a flow rate of 21.5844 ml/s at full opening with 1.48% precision and 93.94% correlation (Y = 225.66 – 2.0232X). The module effectively supports PID-based water level control, enhancing laboratory-based process automation education.
