Application of Case Study Learning to Support Project-Based Learning to Develop Critical Thinking Skills of Mechatronics Technicians

The beverage industry has adopted automation technologies to enhance efficiency. However, the use of highspeed machinery can lead to problems caused by component wear and tear. In this context, mechatronics technicians play a crucial role in promptly analyzing and resolving machine issues. This study aims to present the application of Project-Based Learning (PjBL) integrated with Case Study Learning and the 8D Disciplines as a framework to develop the critical thinking skills of mechatronics technicians. Project-Based Learning serves as the foundational instructional framework, allowing learners to engage in hands-on, real-world problem-solving through project execution. The 8D Disciplines are used to reinforce the process by introducing a step-by-step problemsolving methodology, while case study learning is incorporated to expose learners to realistic scenarios that train them in identifying causes and consequences. As a result, machine breakdown time was reduced by as much as 84.32%. Furthermore, the assessment of critical thinking skills before and after the training showed a statistically significant improvement. Activity-based assessments also indicated a significant increase in average scores between the first and second activities, confirming improvements in critical thinking and problem-solving abilities. Participants demonstrated the ability to accurately describe problems, identify symptoms using recorded data, and follow a systematic problem-solving process. Overall, the findings demonstrated that this integrated learning framework is effective and adaptable for use in both industrial and educational settings, as well as in the professional development of personnel within organizations.
