Developing a Practicum Module for Air Conditioning (AC) Systems in Refrigeration Engineering Course

Abstract

This study aimed to develop a feasible air conditioning (AC) system practicum module, evaluate its feasibility based on expert validation, and assess student responses to the developed module. A research and development (R&D) approach using the ADDIE model, including analysis, design, development, implementation, and evaluation stages, was employed in the research. The procedure involved a needs analysis, initial module design, product development, expert validation (content and media), and student trial. The subjects included subject-matter experts, media experts, and students as module users. Data were collected using expert validation sheets and student response questionnaires, and analyzed through qualitative and quantitative descriptive techniques. The results showed that content and language feasibility validated by subject-matter experts achieved 93% (highly feasible), media feasibility validated by media experts reached 97% (highly feasible), and student responses reached 86.09% (highly feasible). Therefore, the developed AC system practicum module demonstrates a high level of feasibility and has strong potential as a supporting learning resource for practical activities.
