Abstract

The lack of standardized teaching materials hampers practical learning of AC installation systems at SMK Negeri 5 Padang. Although AC trainers are available, students lack structured, industry-standard practice guides. This study aims to develop and assess the validity and practicality of a 21st-century competency-based teaching module for AC installation systems in vocational schools. Using the Research and Development (R&D) method with the 4D model (Define, Design, Develop, Disseminate), this study emphasizes the Develop stage for feasibility testing, while the Disseminate stage is limited to a trial at SMK Negeri 5 Padang. This study involved needs analysis, module and worksheet design, validation by material and media experts, and practicality testing by teachers and students. Validation results confirmed the module's feasibility in terms of content, visuals, language, and alignment with 21st-century learning principles. The practicality test showed the module was user-friendly, logically structured, and supported learning objectives. Each worksheet was equipped with a 4C-based assessment rubric to help teachers evaluate learning outcomes objectively. Therefore, this module is considered valid, practical, and appropriate for teaching refrigeration and air conditioning engineering in vocational settings. This research suggests that this module can serve as a reference for similar programs, supporting more structured, measurable, and student-centered learning in refrigeration and air conditioning engineering majors.
