THE MOSQUE DOME ASSEMBLING IN AN ETHNOMATHEMATICAL PERSPECTIVE FOR A LEARNING APPROACH

Abstract

Ethnomathematics is a mathematics learning approach with cultural media around students. Therefore we need the right approach in the learning process to present mathematics that is close to student life so that students have high motivation in learning mathematics. This study aims to determine the process of making mosque domes and ethnomathematics-based learning by modeling mosque domes. This study uses a qualitative research approach with ethnographic methods. Respondents of the study were dome makers, vault designers, and company managers of Seribu Kubah Co.Ltd. The main instrument is the researcher using observation, interview, and documentation guidelines. The results showed that first, the process of making the mosque dome includes three steps, namely ordering the dome, designing and manufacturing the dome components, and assembling the dome. Second, many mathematical concepts are contained in the dome of the mosque including ellipses, circles, rectangles, and triangles. Due to the application of mathematical concepts in making mosque domes, the results of mosque dome modeling can be used in classroom learning, especially for learning resources for geometry material. In-depth studies of ethnomathematics are applied by certain communities to bridge mathematics practiced in society with mathematics learned in schools.
