Abstract

In essence, mathematics is a science that comes from everyday life and human culture. However, many students perceive that mathematics is far from everyday life and student culture. This is because mathematics in schools is taught formally and not related with the real life of students. Therefore, we need an approach that can connect mathematics with real life. One approach that can be used is ethnomathematics. In Yogyakarta, there are many cultural objects that contain mathematical concepts. One of them is the cultural object of the Taman Pelangi Yogyakarta which is around the Monumen Jogja Kembali. However, the mathematical concepts contained in Taman Pelangi Yogyakarta have not been used in the context of learning at school. So, this study aims to explore the mathematical concepts in the Taman Pelangi Yogyakarta to be used as a context for learning mathematics. The method that was used in this research is ethnography. The data in this research were obtained from a literature review and documentation. Then the data was analyzed by descriptive analysis. The results of the research show that Taman Pelangi Yogyakarta has many colorful lanterns with various shapes made by applying the concept of geometry. It is hoped that the findings of this study can be used as a reference for teachers and researchers to develop learning based on ethnomathematics approach. In addition, this research not only can bridge mathematics with culture but also can strengthen the identity and the social culture value of students.
