ETHNOMATHEMATICS IN PEKALONGAN SINTREN DANCE: ANALYSIS OF GEOMETRY AND SYMMETRY IN LOCAL CULTURAL MOVEMENTS

Abstract

Etymologically, the word "sintren" is formed from two syllables, namely "si" which means "she" and "tren" which is the name for a princess. Sintren art is a traditional art that developed in the northern coastal region of Java, especially in Central Java and West Java. As a performing art that has elements of magic and ritual, Sintren is an important part of local community life. Sintren not only has aesthetic and spiritual value, but also contains mathematical concepts in it. This research was conducted using qualitative methods and an ethnographic approach. Using data collection techniques, namely Literature Study and observation, the subjects of this research are Sintren dancers. The results of the research show that there are various mathematical concepts reflected in Sintren art, such as geometric concepts in dance floor patterns, geometric transformations in dance movements, geometric patterns in costumes and musical instruments used during performances. This shows that Sintren art has the potential to be a source of contextual learning in teaching mathematics based on culture. By integrating ethnomathematics elements from Sintren art, it is hoped that students can understand mathematical concepts more effectively while recognizing and preserving local culture.
