Studi Etnomatematika: Eksplorasi Konsep Bangun Datar pada Rumah Adat Balla Lompoa

Abstract

Penelitian ini bertujuan untuk mengungkap konsep matematika, terkhusus pada materi geometri bangun datar, serta nilai-nilai budaya yang terkandung dalam arsitektur dan artefak pada bangunan rumah adat Balla Lompoa di Sulawesi Selatan. Jenis penelitian ini adalah penelitian kualitatif dengan pendekatan etnomatematika, teknik pengumpulan data yang digunakan adalah observasi, wawancara, dan dokumentasi. Penelitian ini menerapkan triangulasi teknik, teknik analisis data yang digunakan yaitu reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian ini menunjukkan bahwa rumah adat Balla Lompoa di Kabupaten Gowa, Sulawesi Selatan, memiliki berbagai konsep geometri bangun datar yang terintegrasi dalam arsitektur dan artefaknya. Unsur-unsur seperti persegi, persegi panjang, segitiga sama sisi, segitiga sama kaki, lingkaran, trapesium, dan belah ketupat ditemukan dalam berbagai elemen bangunan dan artefak tradisional. Selain aspek matematis, rumah ini juga memiliki nilai filosofis dan budaya yang kuat, mencerminkan struktur sosial dan kepercayaan masyarakat Gowa.Mathematics as a universal science has long been a part of human life, including in aspects of culture and architecture, as found in the architecture and artifacts of the Balla Lompoa traditional house in South Sulawesi. This study aims to reveal the concept of mathematics, especially in the material of flat geometry, as well as the cultural values contained in the architecture and artifacts of the Balla Lompoa traditional house in South Sulawesi. This type of research is qualitative research with an ethnomathematics approach. Data collection techniques used are observation, interviews, and documentation. This study applies technical triangulation. Data analysis techniques used are data reduction, data presentation, and drawing conclusions. The results of this study indicate that the Balla Lompoa traditional house in Gowa Regency, South Sulawesi, has various flat geometry concepts that are integrated into its architecture and artifacts. Elements such as squares, rectangles, equilateral triangles, isosceles triangles, circles, trapezoids, and rhombuses are found in various elements of traditional buildings and artifacts. In addition to the mathematical aspect, this house also has strong philosophical and cultural values, reflecting the social structure and beliefs of the Gowa people. The implications of this study are that it not only enriches ethnomathematics literature but also contributes to a culture-based mathematics learning approach, which can improve students' understanding and interest in geometry material through local cultural contextualization.
