Abstract

Pembelajaran pecahan di sekolah dasar masih menghadapi berbagai kendala, terutama rendahnya pemahaman konsep siswa akibat pembelajaran yang bersifat abstrak dan kurang kontekstual. Salah satu solusi yang Dditawarkan adalah integrasi pembelajaran matematika dengan bantuan alat peraga berbasis budaya lokal. Penelitian ini bertujuan untuk menganalisis pengaruh integrasi etnomatematika melalui alat peraga payet (manik-manik) terhadap pemahaman konsep pecahan siswa sekolah dasar. Metode penelitian menggunakan pendekatan kuantitatif dengan desain quasi eksperimen tipe pretest–posttest control group. Subjek penelitian terdiri dari siswa kelas IV sekolah dasar yang dibagi menjadi kelas eksperimen dan kelas kontrol. Kelas eksperimen menerima pembelajaran pecahan berbasis etnomatematika menggunakan alat peraga payet, sedangkan kelas kontrol menerima pembelajaran konvensional. Instrumen penelitian berupa tes pemahaman konsep pecahan yang telah diuji validitas dan reliabilitasnya. Data dianalisis menggunakan uji statistik inferensial, termasuk uji normalitas, uji homogenitas, dan uji perbedaan rata-rata. Hasil penelitian menunjukkan adanya perbedaan signifikan dalam pemahaman konsep pecahan antara siswa yang mengikuti pembelajaran menggunakan alat peraga payet berbasis etnomatematika dan siswa yang mengikuti pembelajaran konvensional. Dengan demikian, integrasi etnomatematika melalui alat peraga payet terbukti efektif dalam meningkatkan pemahaman konsep pecahan siswa sekolah dasar.

Abstract

Mathematics learning in elementary schools continues to face challenges in connecting abstract mathematical concepts with students' real-life experiences, particularly in learning circle concepts. This condition often limits students' conceptual understanding because instruction tends to emphasize procedural knowledge rather than meaningful contextual learning. Although Realistic Mathematics Education (RME) has been widely recognized as an approach that promotes contextualized mathematics learning, the integration of local cultural contexts into RME remains limited, especially through the use of kompang, a traditional Malay musical instrument with distinctive circular characteristics. Therefore, this study aims to explore the implementation of Realistic Mathematics Education based on kompang in teaching circle concepts at the elementary school level. A qualitative approach employing a case study design was adopted. Data were collected through classroom observations, semi-structured interviews, documentation, and analysis of instructional materials. The data were analyzed using the interactive model of Miles, Huberman, and Saldaña, including data condensation, data display, and conclusion drawing and verification. This study is expected to provide an in-depth understanding of how kompang can serve as a meaningful contextual basis for implementing RME in teaching circle concepts, while offering practical insights into the integration of local cultural resources in elementary mathematics learning.
