Studi Etnomatematika: Bangun Datar Pada Motif Karya Seni Kriya Kain Ulos, Sumatera Utara

Culture and mathematics are two things that can be combined in a lesson. In everyday life, culture is often seen as having nothing to do with mathematics. In the process of learning mathematics, teachers can extract knowledge from students from the life of the community around where they live. The environment can be a source of learning mathematics in real life. The environment in question is one of them is culture. Ethnomatematics is a combination of mathematics with cultural elements. One of the ethnomathematics objects is traditional cloth motifs. Each region certainly has its own culture, including the traditional cloth that is characteristic of that area. Ulos Batak cloth is one of the distinctive cultures of the Batak people. Exploration and exploring the mathematical concepts contained in the Ulos Batak cloth motifs that can be used as a source of learning mathematics and as an effort to develop ethnomathematics as a basis for learning mathematics is the aim of this exploratory research with an ethnographic approach. Through exploration and literature study, it can be concluded that there is a geometric concept of a flat shape in several Ulos Batak cloth motifs. The structures are square, rectangle, triangle, rhombus, and kite. Learning mathematics using ethnomathematics objects is expected to make students more active in learning mathematics,  able to understand the importance of learning mathematics as well as understand the cultural heritage that exists in their respective regions
