Ethnomathematics exploration geometry on the museum of Semedo and integration into elementary school mathematics learning

Ethnomathematics is an approach to learning mathematics that integrates with a culture. The purpose of this research is to 1) explore the concept of ethnomathematics at the Museum of Semedo. 2) The integration of etnomatematics geometry for the mathematical development of primary school. The type of research used is qualitative with an ethnographic approach. Research subjects, head of unit, and some museum officers Data is collected through observations, interviews, and documentation. Data validity with triangulation of methods and sources Data analysis techniques use flow methods, data collection, data reduction, data presentation, and inference. The results of the research showed that the existence of the concept of ethnomathematics geometry in the museum, in particular, the concept of geometry volume and Its integration into the mathematics learning of the elementary school. The concept of ethnomathematics geometric shapes that exist in buildings and collection in the museum, especially geometric material such as, beams, cubes, tubes, cone, and balls. Ethnomatematics provides a learning experience that integrates mathematics with culture so that students can more easily understand the geometric material in concrete terms.
