Abstract
Vocational secondary schools (SMK) tasked with producing industry-ready graduates frequently lack structured, validated instructional materials for complex automation equipment. This study reports the design, development, and validation of a Problem-Based Learning (PBL) Jobsheet Module for the Panasonic PLC-based Pick and Place Trainer Kit, programmed through FPWIN Pro 7. Following a Research and Development (R&D) approach using the Four-D (4D) model, limited to the Develop phase, five progressive jobsheets were constructed and evaluated for validity by subject-matter and instructional media experts, and for practicality by one vocational teacher and ten Grade XI Industrial Automation students at SMK Pembangunan Teknologi Robotik UNP, Padang, Indonesia. Expert validation yielded a composite score of 91.67% (Very Valid), comprising 89.58% for content validity and 93.75% for media validity. Practicality testing returned an overall mean of 93.6% (Very Practical), with teacher and student ratings of 93.8% and 93.5%, respectively. Qualitative feedback indicated that the PBL problem scenarios reduced cognitive load, enhanced procedural independence, and improved learners' confidence in troubleshooting electro-pneumatic systems. These findings confirm that integrating authentic industrial problem scenarios into structured jobsheet modules produces highly valid and practical teaching materials aligned with Industry 4.0 competency demands, while also providing a replicable design framework for vocational automation educators.
