“…At present, there has been a lot of research on ethnomathematics, as the researchers have described in the introduction, namely exploration in traditional Javanese games where mathematical concepts have been found, namely in the form of number operations, flat shapes, congruence, number comparisons, and relations [14], ethnomathematics exploration of the musical instrument style of the marawis art as a source of learning mathematics where mathematical concepts have been discovered, namely in the form of flat plane geometry and mathematical concepts which include the concepts of translation, reflection, folding symmetry, rotating symmetry, acute and obtuse angles, and circular planes [15], exploration of Cirebon Trusmi batik ethnomathematics to reveal the philosophical values and mathematical concepts that have been found in mathematical concepts, namely the concepts of symmetry geometry, transformation (reflection, translation, and rotation), and congruence [16], and ethnomathematics in traditional games of cranks and tops typical of a Sundanese culture where mathematical concepts have been found, namely in conventional cranks games there are flat geometric concepts, namely square, rectangle, semicircle, and the idea of counting, while for tops there are mathematical elements in the form of tubes [17]. It can be concluded that various cultures from various regions as objects of research.…”
