<![CDATA[In the era of technological advancement, education must continually innovate by utilizing effective learning media, such as augmented reality (AR). AR creates an interactive and engaging learning environment by combining real-world visualization with virtual objects, making it a focus in education to enhance conceptual understanding. This study aims to analyze the validity, practicality, and effectiveness of AR-based learning media in improving students' conceptual understanding of computer hardware materials in Informatics subjects. The research was conducted in classes X TKJ 1 and X TKJ 2 at SMK Negeri 5 Padang, using multiple-choice objective test instruments and questionnaires. The results indicate that the use of AR-based learning media has a significant impact on improving students' conceptual understanding. This is evidenced by the hypothesis test results showing a sig. (2-tailed) value of 0.00 (<0.05) and an N-gain score of 0.7293 (high category), with an effectiveness percentage of 72.92%. AR-based learning media was deemed highly feasible as supplementary learning media based on expert validation (95%), as well as practicality questionnaires from teachers (95%) and students (87%). The advantages of AR media include realistic visualization, the ability for repeated observation, a more interactive learning experience, and efficiency in the use of teaching aids. Thus, the implementation of AR in learning has proven effective in enhancing students’ conceptual understanding and providing a more engaging and meaningful learning experience.]]>
