Understanding concepts is essential in physics education, as this subject emphasizes the practical application of concepts over rote memorization. This approach helps prevent students from occurring misconceptions. Moreover, learning motivation can raise enthusiasm for learning physics to achieve the expected goals. However, evidence suggests that both variables show low levels. Therefore, this study aims to develop valid, practical, and effective Engklek game ethnoscience-based edutainment learning materials (EGEBLM) to improve students' physics concept understanding and learning motivation. This research utilizes the 4D type (Define, Design, Develop, Dissemination) to fulfill the quality test of the developed learning materials. The sample of this study involved 29 high school students at level XI. The EGEBLM test design used a non-equivalent control group design. Data were analyzed using descriptive and statistical tests, including N-gain, t-test, and MANOVA. The results reveal that EGEBLM is declared valid in content and construct in each component, including syllabus, lesson plans, teaching materials, student worksheets, test instruments, and response questionnaires. Observations indicate that each learning approach's syntax can be effectively implemented ( 3.00), rendering it suitable for educational applications. EGEBLM also meets effective criteria based on descriptive and statistical tests (p 0.05) to enhance conceptual understanding and learning motivation, receiving positive feedback from students to this learning. This learning model combines collaborative discovery learning activities with traditional Engklek games that they have applied everyday, enabling students to understand physics concepts easily and meaningful learning experience. This research has implications as an innovative method in learning physics edutainment, offering an accessible, cost-effective, enjoyable approach while also preserving the Engklek cultural context.
