Studi Etnomatematika dalam Ajaran dan Bangunan Kompleks Pemakaman Sunan Drajat

Abstract

The purpose of this study is to explore the ethnomathematics concept contained in the teachings and buildings in the Sunan Drajat burial complex in Drajat Village, Paciran District, Lamongan Regency, East Java. The focus of the study includes sapta piweling (pepali pitu) and catur piwulang as the moral teachings of Sunan Drajat, as well as mathematical symbols in buildings in the Sunan Drajat burial complex. The research method used is qualitative with an explorative-descriptive approach. Data were collected through direct observation, interviews, and documentation, then analyzed qualitatively with data reduction techniques, data presentation, and drawing conclusions. The findings of this study indicate the uniqueness of the numbers seven and four from the perspective of Javanese philosophy, Islamic teachings, and the concept of numbers in mathematics. In the buildings of the burial complex, the concept of flat geometry (isosceles trapezoid, rectangle, isosceles triangle, and rhombus), spatial geometry (cube, pyramid frustum, and rectangular pyramid), as well as geometric transformations in the form of mirroring, line symmetry, and rotational symmetry were found. This finding has the potential to be a contextual source in the development of local culture-based mathematics learning, especially in geometry and transformation materials, while supporting the preservation of cultural values in society.
