<![CDATA[Traditional cultural practices have become a major focus in the study of ethnomathematics. However, there is still relatively little empirical research that systematically identifies the mathematical concepts embedded in traditional Javanese games. Therefore, this study aims to identify and analyze the mathematical concepts embedded in Jemparingan , a traditional Yogyakarta archery game, and to examine its relevance to mathematics learning. This research employed a qualitative ethnographic approach. Data were collected through participatory observation, field documentation, and semi-structured interviews with Jemparingan practitioners. The data was analyzed using thematic analysis, which includes data organization, in-depth reading and data recording, coding, and data interpretation. The findings revealed three mathematical concepts: proportional relationships in equipment measurement, acute angles in bow positioning, and integer operations in score calculation. These patterns are closely associated with the Javanese philosophy of hening-hening (inner calmness), which emphasizes calmness and balance. Overall, this study contributes to ethnomathematics by providing empirical evidence that traditional games can function as authentic representations of mathematical thinking while supporting appreciation of local cultural heritage. These findings encourage educators to consider the integration of local culture into more meaningful mathematics instruction.]]>
