Ethnomathematics Exploration of Traditional Bugis-Makassar Food Based on The Mathematization of Iceberg Realistic Mathematics Education

Abstract

This study aims to explore geometric ideas in traditional food called Tumpi-Tumpi, a typical Bugis Makassar cuisine, and to develop problem-solving abilities using the Iceberg Realistic Mathematics Education (RME) model. This study used a qualitative study with descriptive exploration. Data was collected through observation, interviews, and documentation. Based on the design of Miles and Huberman, the data analysis technique consisted of data reduction, data presentation, and conclusion/verification. According to data collection results, the traditional Bugis-Makassar cuisine Tumpi-Tumpi contains ethnic mathematical components (geometrical concepts), namely, the plane figure of an equilateral triangle, and is used to solve mathematical problems. The Iceberg RME math technique utilized "the model of" and "the model for" to determine an equilateral triangle's features, area formula, and perimeter. Iceberg-based ethnomathematics collaboration may enhance high school student's interest in learning.
