Ethnomathematics in The Gayo Traditional House (Case Study of Umah Kantur, Kung Village, Pegasing District, Aceh Tengah)

Umah kantur is a traditional house in the form of a house on stilts built in 1925. Umah kantur was built under the influence of the development of traditional houses such as umah pitu ruang and rumoh Aceh. The typology of geometric shapes in umah kantur has similarities with the types of traditional houses. Like traditional houses, the construction of umah kantur is carried out using ethnomathematics methods. This study aims to identify the typology of elements in the umah kantur and determine the measurement system in the umah kantur. The research method is descriptive qualitative with data collection techniques through collecting primary data, secondary data, and computing. After data collection and computation, the results show that umah kantur adapts the characteristics of umah pitu ruang and rumoh Aceh with the building measurement
