ETHNOMATHEMATICS: EXPLORATION OF GEOMETRY CONCEPTS IN TIBAN MOSQUE ARCHITECTURE

Abstract

Ethnomathematics is an event for learning education and culture because the connection between education and culture cannot be separated. Research This aims for a geometry draft in the Tiban Mosque, Malang architecture, which can be used as a medium for understanding draft geometry. Research This is implemented qualitatively with an approach to ethnography. The instrument's central Study is the researcher itself. Data was collected using technique studies library, observation, interviews, and documentation. Informants in Study This is an inhabitant of the Tiban Mosque; students at the time were officers who provided information and one of the craftsman ornaments. Based on the results, the Study found that the draft gets up flat, builds space, and transforms geometry. The concept gets up flat found , among others, square, square length, circle, rhombus, right-angled trapezoid, triangle on the same side, quarter circle, and half circle. Concept get up space found including cones, blocks, cylinders, and spheres. The concept of transformation geometry included reflection, dilation, translation, and rotation.
