Development of Learning Media Practicum Air Conditioning System Based on Problem Solving in Vocational Education

Abstract

Learning media acts as a tool to convey knowledge and skills from teachers to students. This study aims to: (1) develop problem solving-based learning media; (2) revealing the feasibility of the problem solving-based air-cooling system practicum learning media that was developed to be applied; (3) revealing the effectiveness of practical learning media based on problem solving of the air conditioner system. This research is learning media development research that refers to the ADDIE development procedure by the branch. The stages in this research include: (1) analysis, (2) design, (3) development, (4) implementation, and (5) evaluation. The subjects of this research trial were limited to 7 students, and the broad trial was 18 students. Collecting power in this study using observations, interviews, documentation, and measurements. The results of this study are as follows: (1) the learning media developed consists of a set of practicum test equipment units equipped with an analysis table for the diagnosis of damage to the air conditioner system. (2) the results of the feasibility assessment by learning media experts are included in the very feasible category with a percentage result of 94.3%; (3) the results of the effectiveness test show that the problem solvingbased learning media developed is effective as seen from the results of student practicum.
