<![CDATA[This study aims to determine the effectiveness of augmented reality-based learning media on student learning outcomes regarding computer hardware within the Informatics subject. Currently, instruction on computer hardware relies heavily on conventional media, such as textbooks and oral explanations, which have limited ability to support students' visual understanding of abstract components. Consequently, students tend to be passive, struggle to maintain focus, and often achieve learning outcomes below the minimum mastery criteria. This study employs the ADDIE development model and a quasi-experimental design, specifically a posttest-only control group design. The results indicate that augmented reality-based learning media significantly improve student learning outcomes compared to conventional learning media. The effectiveness of the augmented reality-based learning media is demonstrated by an n-gain score of 0.76 in the experimental group, which falls into the "effective" category. Thus, this augmented reality learning medium is effective in the learning process. Furthermore, statistical analysis yielded a t-calculated value of 6.971, which is substantially higher than the t-table value of 1.995. Since the t-calculated value exceeds the t-table value and the significance level is below 0.05, the null hypothesis (H₀) is rejected, and the alternative hypothesis (H₁) is accepted. Therefore, it can be concluded that there is a statistically significant difference in the mean posttest scores between the experimental group and the control group.]]>
