Abstract

In attempt to explore Yogyakarta, the heritage city of Indonesia, the well known landmark, Tugu Pal Putih and the Yogyakarta Imaginary Line is explored. The purpose of this paper is to describe that this cultural context may be used as a reference for geometry learning. The method used in this research is a descriptive qualitative involving two historian experts in interviews. The results are that this line can be explored through ethnomathematics studies based on points, straight lines, comparison of distances between points on the imaginary line and the extension of the imaginary line. This line can be illustrated by an imaginary point located at the Tugu Pal Putih as the starting point to focus on thinking of the mathematical object. This line not only divides Yogyakarta imaginatively but also according to natural boundaries such as rivers. The extension of the imaginary line forms an area called the fertility area. The description of the patterns formed on the Yogyakarta Imaginary Line through ethnomathematics is expected to be used further as materials in the mathematics learning process.

Abstract

Differences in understanding between religions and cultures characterise the emergence of intolerance in society. These conditions can contribute to the breakdown of religious life and result in subjective interpretations of truth that disregard others' perspectives. The research method used a mixed method with a sequential exploratory model. Data collection techniques included interviews, observations, literature studies (qualitative), and questionnaires (quantitative). This study aims to reveal the dynamics of cultural da'wah, the process of Muhammadiyah internalisation, and the relationship between Muhammadiyah and syncretic Islam in shaping the value of tolerance in Yogyakarta. The results of the study show several things, namely 1) there are dynamics of cultural da'wah described by the concepts of hablumminallah and hablumminannas with examples of each entity's attitude towards the night of Suro; 2) there is involvement of each entity in Muhammadiyah activities with conservative teaching materials and adaptive methods, as demonstrated by the processes of acculturation, assimilation, and accommodation in each entity's religious activities; and 3) the phenomena observed in this case study illustrate the relationship between Muhammadiyah and Syncretic Islam in shaping the value of tolerance in Yogyakarta. The relationship between the two can fulfil the indicators of the active tolerance model by being able to coexist peacefully and strive to respect diversity.
