The teaching of algorithm concepts to novice learners presents persistent challenges due to the abstract nature of computational thinking and the difficulty of visualizing sequential processes. This study aimed to develop and evaluate the usability of an Augmented Reality-based learning medium for introducing algorithm concepts to tenth-grade students. The research employed the Multimedia Development Life Cycle (MDLC) methodology, encompassing concept, design, material collecting, assembly, testing, and distribution stages. The resulting Android application integrates physical flowchart cards with interactive three-dimensional animations, where students arrange cards in correct sequences to trigger animated characters that visually demonstrate algorithm execution. The application was validated by two media experts and one subject matter expert, then evaluated by 38 tenth-grade students using the System Usability Scale (SUS). Expert validation results showed mean Aiken's V coefficients of 0.93 for both media and material experts, with feasibility percentages of 94.4% and 95% respectively, categorizing the product as very feasible. Black box testing confirmed 100% functional success across all application features. The user evaluation yielded a mean SUS score of 71.31, which corresponds to a Grade of C+, an adjective rating of "Good," and falls within the "Acceptable" range according to Sauro's interpretation framework. Notably, 94.7% of participants had no prior experience with similar AR applications, indicating that usability was achieved despite technological novelty. Qualitative feedback revealed positive student engagement and appreciation for the interactive visualization approach. This study concludes that the developed AR learning medium is feasible and acceptable for introducing algorithm concepts, transforming abstract flowchart logic into observable, interactive experiences that support foundational computational thinking development.
