Etnomatematika pada Masjid Haji Muhammad Cheng Hoo Banyuwangi sebagai Modul Ajar Matematika Fase D

Abstract

Despite the importance of mathematics, most students still consider that mathematics is difficult. The lack of meaningfull learning is one of the reasons why mathematics is difficult for students to understand. Teachers should link these mathematics concepts with daily existance, one of which is culture. Mathematics in culture is also known as ethnomathematics. The purpose of this qualitative research with an ethnographic approach is to explore the ethnomathematics of Haji Muhammad Cheng Hoo Banyuwangi Mosque and to apply it as a mathematics teaching module for SMP/MTs students (Phase D) based on Kurikulum Merdeka. The mosque’s caretaker and contractor are the subjects of this research. Through observations of mosque building, interviews with research subjects, object documentation, and literature studies, it can be concluded that there are several geometric concepts such as flat shapes, spatial shapes, congruence and similarity, as well as geometric transformations in some parts of the building, including the dome, pillars, ceiling, mihrab, ornaments, and gate of Haji Muhammad Cheng Hoo Banyuwangi Mosque. Then, the result are used as topic problems in “Geometry Transformation on Coordinate Plane” teaching module for class IX SMP/MTs (Phase D) as the implementation of contextual learning in schools.
