This study was conducted to determine the effectiveness of using Assemblr Edu learning media in improving students’ conceptual understanding of the circulatory system. This research employed an experimental method with a quasi-experimental design, specifically the pretest–posttest non-equivalent control group design. The study was carried out in Grade VIII at SMP Negeri 4 Seponti. The research population consisted of all Grade VIII students, with a total sample of 32 students. The research instrument used was a written test consisting of five essay questions. The data were analyzed using prerequisite tests, namely the normality test and homogeneity test. Hypothesis testing was conducted using the paired sample t-test with the assistance of IBM SPSS version 25. The results showed that the significance value (Sig. 2-tailed) was 0.000 < 0.05, indicating that H₀ was rejected and H₁ was accepted. These findings demonstrate that Assemblr Edu learning media is effective in improving students’ conceptual understanding of the cardiovascular system material.
