Aru ethnomathematics: Exploration of mathematical concepts in Daret Damar Jan game and its integration in mathematics learning in elementary school

Various research on traditional games has been reviewed in previous studies, including layang-layang, congklak, galah panjang, and guli. However, there has been no research on the Daret Damar Jan game. Previous research has only focused on exploring mathematical concepts in traditional games without integrating these concepts into mathematics learning at school. Therefore, this research aims to explore the mathematical concepts in the traditional game Daret Damar Jan and integrate them into mathematics learning in elementary schools. A descriptive exploratory method was used in this study. The participants in this study were 2 local cultural figures, 6 children of Dokabarat village, 1 teacher, and 22 second-grade students at a public elementary school. Data was collected through participatory observation, in-depth interviews, documentation studies, and concept understanding tests. The data were then analyzed using thematic and descriptive analysis. The results of the research indicate that the concepts of symbols, units, and arithmetic operations of natural numbers were found in the Daret Damar Jan game. The utilization of the Daret Damar Jan game as a learning resource can improve students' concept understanding of natural number counting operations material from 40.91% to 77.27% and is in the high category.
