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.

Abstract

The implementation of Field Work Practice (PKL) in vocational schools still faces administrative and monitoring challenges due to reliance on manual reporting systems. These limitations affect reporting efficiency, transparency, and teachers' ability to monitor student activities in real time. This community service activity aimed to implement and assist the use of a web-based PKL monitoring system at SMK Nasional Makassar to support digital monitoring, reporting, and evaluation of PKL activities. The implementation process included needs analysis, system design, implementation, user socialization, mentoring, and evaluation using the Waterfall approach. Data were collected through observation, interviews, and literature review. System evaluation was conducted through Black Box Testing and User Acceptance Testing (UAT). The Black Box Testing results showed that all main system functions operated properly in accordance with user requirements. Furthermore, the UAT results showed a feasibility percentage of 88.5%, indicating that the system was categorized as “Very Feasible.” The implementation of the system improved the effectiveness of real-time monitoring, digital reporting, data management, and administrative efficiency of PKL activities in vocational schools. The findings demonstrate that the web-based monitoring system can effectively support digital transformation in vocational education management.
