Development of Interactive Learning Media for the Lathe Machining Subject among Twelfth-Grade Mechanical Engineering Students at SMK Muhammadiyah 3 Yogyakarta

Abstract

This study aims to identify the characteristics and evaluate the feasibility of an interactive learning media developed for the Lathe Machining subject, specifically addressing Basic Competency 3.1 for twelfth-grade Mechanical Engineering students at SMK Muhammadiyah 3 Yogyakarta. The research employed a Research and Development (R&D) approach that followed the Four-D (4D) model, which consists of four systematic stages: Define, Design, Develop, and Disseminate. In the define stage, the researcher analyzed learning needs, content structure, and competency standards to determine the instructional requirements of the media. The design stage focused on creating a prototype with both conceptual and visual frameworks, including a storyboard and flowchart. The develop stage involved constructing and validating the media through evaluations by subject matter experts and media experts, followed by revisions based on the obtained feedback. In the disseminate stage, the final product was packaged and distributed for classroom use. The resulting interactive learning media contains five main menus: About the Media, Instructions, Learning Materials, Evaluation, and References. It integrates text, images, audio, video, and animation across 80 pages with a total file size of 236 MB. The navigation features include Home, Exit, Sound, Next, Back, Cancel, and Table of Contents, which improve user interaction and accessibility. The instructional content covers trapezoidal threads, worm threads, eccentric shafts, and turning equipment, and it aligns with the 2013 Curriculum’s scientific learning approach. The feasibility assessment results show that the developed media is highly feasible, as indicated by expert validation with an average score of 3.31, categorized as very feasible. Furthermore, field trials involving students resulted in an average score of 3.23, categorized as feasible. These findings indicate that the interactive learning media is pedagogically appropriate, user-friendly, and suitable for implementation in vocational machining education.
