Rhythmic activity is part of physical education learning that has an influence on students' rhythmic skills. This study aims to produce a rhythmic activity learning model based on Javanese traditional dance to improve the rhythmic skills of elementary school students. This research was pursued by using the research & development method. The research procedure consisted of four stages; Stage 1. Preliminary study (N=30); Stage 2. Model development; Stage 3. Model validation (N=5); and Stage 4. Model trial (N=64). The data collection technique used is in the form of a model feasibility test. Data analysis through Confirmation Factor Analysis (CFA) is summarized in the form of quantitative and qualitative descriptive analysis. The results showed that: (1) The rhythmic activity learning model based on Javanese traditional dance has 7 warm-up movements, 15 core movements, and 4 cooling down movements;(2) The learning model of rhythmic activity based on Javanese traditional dance is effective for improving students' rhythmic skills, in terms of the aspects of memorizing movements (2.738 ± 0.556), the accuracy of movements (3.224 ± 0.529), the flexibility of movements (2.617 ± 0.540), and seriousness of movements (3.158 ± 0.521). Based on the results of the model feasibility test, it is known that the level of implementation of the rhythmic activity model based on Javanese traditional dance is very high at 90.26% and the quality of the rhythmic activity model based on Javanese traditional dance is very high at 92.75%. Through qualitative analysis, it is known that the rhythmic activity model based on traditional Javanese dance is suitable for use in learning rhythmic activities for elementary school students.
