Augmented Reality-Based Learning Media in Computer Systems Subjects

This research aims to develop Augmented Reality (AR)-based learning media in the Computer Systems subject at SMK Negeri 2 Argamakmur, with the hope of increasing the effectiveness and involvement of students in the learning process. This study uses the Research method and Development (RD) with the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The subjects of the study consisted of 30 grade XI students at SMK Negeri 2 Argamakmur. Data collection instruments included questionnaires to measure student and teacher responses, and tests to assess the increase in conceptual understanding. The media feasibility test was carried out through validation by material experts and media experts, as well as limited trials. The results showed that AR-based learning media received a "very feasible" rating from material experts with a score of 88.5% and from media experts with a score of 91.2%. Testing the effectiveness of the media on student understanding showed an increase in learning outcomes with an average pre-test score of 65.3 increasing to 82.7 in the post-test, with a rise of 26.5%. Student responses to this learning media were also very positive, with a percentage of satisfaction reaching 89.4%. Based on these results, it can be concluded that the AR-based learning media developed effectively improves student understanding and can be used as a learning medium in the computer systems subjects.
