Ethnomathematics explores the intersection of mathematics and culture, reflecting how mathematical concepts manifest within local traditions. In culturally rich Indonesia, ethnomathematics holds increasing relevance. This study investigates the presence of mathematical principles in traditional ceremonies, revealing their integration in various cultural elements such as clothing, dances, tools, and ritual. Utilizing a systematic literature review (SLR) method, 27 articles from 2018 to 2024 were analyzed to identity ethnomathematical concepts in Indonesian cultural practices. Findings highlight common patterns like geometric shapes, measurement techniques, and symmetry, evident in artefacts, traditional attire, and ceremonial practices. Additionally, the study underscores the variation in mathematical applications across different regions, reflecting Indonesia’s cultural diversity. These insights have significant implications for developing a more contextual and relevant mathematics education. By connecting mathematical concepts with local culture, ethnomathematics enhances student engagement and understanding, making learning more meaningful and culturally grounded. This approach not only enriches mathematical education but also helps preserve and appreciate Indonesia’s unique cultural heritage, promoting a more inclusive and diverse educational framework.
