Abstract

The study aims to design and develop a freeware application for electrical installation planning analysis. This research is categorized as development research, adopting the RAPID Application Development (RAD) model. The data collection process in this study involved a series of methods, including direct observation of the learning process, in-depth interviews with potential users, and the distribution of structured questionnaires to relevant respondents. The analysis of the collected data was carried out using a quantitative descriptive method, which aimed to describe and interpret numerical data related to the performance and acceptance of the developed application. The overall results of this study indicate that the designed and developed freeware application, as a learning media for electrical installation planning analysis, demonstrates highly satisfactory performance and falls into the "Very Good " category. Specifically, the evaluation of the application's functionality aspect showed a success rate of 100%, indicating that all designed features and functions operate according to the expected specifications. Similarly, the assessment of the user interface aspect also reached a percentage of 100%, implying that the application's interface design is intuitive, easy to use, and overall provides a positive user experience. In addition, in terms of material and media feasibility, it produces "Highly Feasible". The application is determined to effectively incorporate electrical installation planning content pertaining to the learning outcomes of determining cable sizes and circuit breaker capacity. Consequently, this freeware application has significant potential to become an effective learning media in enhancing the understanding and skills of students and practitioners in the field of electrical installation planning.

Abstract

This development research aimed to develop, assess the feasibility, determine student responses, and evaluate the effectiveness of virtual reality-based electrical motor rewinding learning media in enhancing electrical equipment repair competency at Vocational High Schools. Using the ADDIE model (Analyze, Design, Develop, Implement, Evaluate), the study was conducted at State Vocational High Schools 5 Batam, State Vocational High Schools 7 Batam, and S State Vocational High Schools Teladan Batam. The subjects were 11th-grade students specializing in Electrical Power Installation. Data was collected via interviews, questionnaires, and tests. Expert judgment validated the instruments, and Cronbach Alpha confirmed their reliability. Data analysis involved descriptive statistics and t-tests. The study yielded Virtual Reality based electrical motor re-winding learning media, a guidebook, and job sheets. Feasibility tests showed "very feasible" ratings from both material experts (93%) and media experts (83%). Student responses in the experimental group were "very good" (87%). The media proved effective in improving competency, with experimental group post-test scores significantly higher than the control group. The media demonstrated a "moderate" effectiveness level with a gain score of 0.47, and a t-test value of 0.000 indicated that Ho was rejected and Ha accepted, confirming its effectiveness in enhancing electrical equipment repair competency.
