Abstract

Mathematics is considered as a subject that still far from reality and culture. Historically, mathematics has closely related to everyday life, including culture in Lombok West Nusa Tenggara. This culture can explore mathematical concepts to bring mathematics closer to reality and people's perceptions and cultural aspects as the basis for learning mathematics in schools. Therefore, this study explores the elements of geometry transformation in the weaving of the Sasak Sukarara tribe of Central Lombok from an ethnomathematics point of view. This research is qualitative research embracing an ethnographic approach. Data collection methods were carried out through observation and interviews with cultural leaders and native weavers from Sukarara, Central Lombok. The data analysis technique in this study used content analysis and triangulation techniques. The content analysis technique provides detailed data dealing with the weaving culture and habits of the research subjects carried out at the research location. The data source triangulation technique was carried out by comprehensively exploring the relationship between the mathematical knowledge system and the weaving motif culture and looking at the mathematical conceptions that exist in the Sukarara weaving motif. This study showed that in the motifs of wayang, subahnale, keker, four stars, and alang/lumbung, the concepts of reflection and translation could be used as learning resources for geometry transformation materials.Penelitian ini bertujuan untuk mengeksplorasi unsur budaya khususnya budaya sasak masyarakat Sukarara Lombok Tengah seperti pembuatan tenun sasak dalam sudut pandang etnomathematika. Penelitian ini merupakan penelitian kualitatif dengan pendekatan etnografi. Metode pengumpulan data menggunakan wawancara dengan narasumber yang merupakan tokoh adat dan budayawan berpengalaman yang pernah melakukan penelitian tentang masyarakat Sasak, observasi lapangan, dan dokumentasi. Analisis data pada penelitian ini tidak hanya berdasarkan interpretasi peneliti tetapi merupakan susunan pikiran dari anggota masyarakat yang dieksplor keluar oleh peneliti. Penelitian ini mengungkap bukti kepekaan masyarakat Sukarara terhadap konsep geometri yang dipraktikkan dalam membuat tenun. Hasil penelitian ini berpotensi untuk digunakan sebagai titik awal dalam belajar matematika. Sumber belajar yang diturunkan dari budaya Sasak ini, jika dimanfaatkan dengan baik maka akan menciptakan pembelajaran matematika yang bermakna bagi siswa.
