<![CDATA[This study aims to explore mathematical concepts embedded in the cultural heritage. of the Nias people—specifically in the Batu Islands and Tello Island—through an ethnomathematical analysis of the Cucufi, a container for rice and betel nut used in local daily life. Ethnomathematics is a field of study that links mathematical concepts. with the activities, knowledge, practices, and cultural heritage of a community. This approach is significant in mathematics education because it connects abstract concepts with students' real-life experiences and cultural environments, thereby making learning more contextual, meaningful, and accessible. The study employs a qualitative descriptive method with an ethnographic approach. Data were gathered. through observation, interviews, documentation, and an examination of the Cucufi's manufacturing process and physical form. The Cucufi is a cultural artifact woven from the dried, flattened, and dyed stems of a swamp plant known in the Nias language as Sinasa (Eleocharis dulcis), utilizing traditional weaving techniques. Analysis involved identifying the activities, patterns, shapes, dimensions, and geometric structures of the Cucufi and relating them to mathematical concepts, particularly those concerning two-dimensional shapes. The exploration reveals that The Cucufi's form and creation process embody geometric concepts that can serve as a context for mathematics instruction. The findings indicate that the Cucufi Cultural heritage holds potential as an ethnomathematics-based learning resource. helping students grasp mathematical concepts through cultural experiences relevant to their lives. Furthermore, culture-based learning has the potential to boost learning motivation, deepen conceptual understanding, and foster an appreciation for the preservation of the Nias community's local cultural heritage.]]>
