Ethnomatematics is an approach in learning that links mathematics with a culture. Applying ethnomathematics in class is very important, because it can make it easier for students to understand mathematical material by linking it to real world problems. The Arak Jodhang culture is one of the cultures in the form of activities of troop convoys wearing soldier's clothing carrying jodhang. In this culture, various mathematical concepts are found.
