Studi Etnomatematika: Konsep Geometri pada Jajanan Jadul di Pasar Tradisional Ngasem, Yogyakarta

Introduction

Studi etnomatematika: konsep geometri pada jajanan jadul di pasar tradisional ngasem, yogyakarta. Telusuri konsep geometri pada jajanan tradisional jadul di Pasar Ngasem, Yogyakarta. Studi etnomatematika ini mengungkap pola lingkaran & persegi pada Apem, Bakpia, Wingko. Ideal untuk pembelajaran matematika.

Abstract

The purpose of this study is to know the history of traditional culinary in Ngasem Market while exploring its geometric concept. Traditional cakes, when viewed physically, have various forms that still survive today. Therefore, in order to identify and analyze the ethnomathematics concept contained in the snacks sold, this qualitative study uses an ethnographic approach to traditional snacks in Ngasem Market with data collection techniques of field observation, interviews with traders, and documentation. The results of the study revealed that traditional snacks in Apem, Bakpia, and Wingko cakes are still available in Ngasem Market and have geometric patterns. The findings of the identified patterns are in flat shapes of circles and rectangles and one cylindrical space shape. The results of this study provide hope and recommendations that can be used as a model for learning mathematics outside the classroom which can also trigger students to understand the history of local culinary culture.

Review

This study presents an interesting and culturally relevant exploration into the field of ethnomathematics, specifically examining traditional culinary items in Ngasem Market, Yogyakarta. The central objective, as outlined in the abstract, is to uncover the historical context of these traditional snacks while simultaneously identifying and analyzing their inherent geometric concepts. This approach is highly commendable, as it bridges the gap between abstract mathematical principles and tangible cultural artifacts, making mathematics more accessible and relatable through local heritage. The premise of connecting ancient food forms with geometric patterns offers a fresh perspective on how mathematical understanding is embedded within everyday life and tradition. The methodology employed is qualitative, utilizing an ethnographic approach, which is well-suited for a study aiming to delve into cultural practices and their embedded mathematical concepts. Data collection techniques, including field observation, interviews with traders, and documentation, appear robust for gathering rich descriptive data. The study successfully identified specific geometric patterns in traditional snacks such as Apem, Bakpia, and Wingko cakes. The findings clearly state the presence of flat shapes like circles and rectangles, alongside one cylindrical space shape. While these findings demonstrate the fundamental presence of geometry, a more detailed discussion on the *complexity* or the *specific cultural significance* of these shapes beyond their mere identification would further enrich the mathematical and ethnographic analysis. The practical implications and recommendations stemming from this research are particularly valuable. The abstract highlights the potential for these findings to serve as a model for out-of-classroom mathematics learning, effectively leveraging local culture to engage students and foster an understanding of mathematical concepts alongside culinary history. This educational application is a significant contribution, offering tangible ways to integrate ethnomathematics into pedagogical practices. Overall, this study makes a solid contribution by meticulously documenting geometric forms within a specific cultural context, thereby reinforcing the idea that mathematics is not an isolated discipline but an intrinsic part of human culture and tradition.
