Exploration of Comparative Concepts in the Ethnomathematics of The Buton Traditional House

Abstract

Abstract The Buton community has practiced mathematical culture in the form of a Buton traditional house called banua tadha (right house). The purpose of this study was to explore the comparative concepts in the ethnomathematics of the Buton traditional house. This research is qualitative research with an ethnographic approach. The results of this study indicate that every Buton traditional house contains several comparative concepts in the ethnomathematical: (1) the width of the door and the width of the stairs, (2) the walls of the house and the tutumbu , (3) the width of the house and tutumbu , (4) wall and pillar heights, (5) the height of the bhate and the length of the limana bathe , (6) the height of the front wall to the height of the side walls, (7) the width of the stair post with the size of the rungs of the stairs, and (8) wall height and house pole height, and (9) the shape of a right triangle formed by a crutch ( konta ), a pole ( ariy ), and a buffer ( tadha ). These comparisons can be used in learning mathematics to pass on the ethnomathematical local wisdom of the Buton traditional house.
