Abstract


Suku Boti sebagai salah satu suku tertua di pulau Timor, Nusa Tenggara Timur yang kaya akan warisan budaya. Keunikan budaya Boti perlu dijaga dan dilestarikan karena merupakan salah satu budaya asli Indonesia. Penelitian ini adalah penelitian kualitatif berdesain etnografi yang bertujuan untuk mengeksplorasi unsur-unsur geometri yang terdapat dalam budaya suku Boti. Subjek dalam penelitian ini yaitu masyarakat suku Boti Dalam yang masih tertutup terhadap budaya modern dan menjalankan tradisi budaya Boti dalam kehidupan sehari-hari. Objek yang diteliti dalam penelitian ini yaitu lopo, tup mahae, tobe, dan sene. Teknik analisis data yang digunakan dalam penelitian ini yaitu analisis taksonomi. Hasil penelitian menunjukkan bahwa konsep-konsep geometri meliputi aksioma titik, garis, dan bidang, konsep garis singgung, konsep luas dan volume bangun datar, konsep luas dan volume bangun ruang, serta konsep kekongruenan. Selain itu, kemampuan-kemampuan matematis seperti kemampuan representasi, kemampuan visual spasial, kemampuan koneksi, dan kemampuan pemecahan masalah dapat dikembangkan berdasarkan unsur-unsur geometris pada budaya suku Boti. Hasil eksplorasi ini dapat digunakan oleh para guru matematika untuk mengembangkan pembelajaran geometri di kelas berbasis budaya Boti.

 

Boti as one of the oldest tribes on the Timor Island, East Nusa Tenggara, has a lot of cultural heritage. The uniqueness of Boti culture needs to be preserved because it is one of Indonesia's original cultures. This is a qualitative research with ethnographic design which aimed to explore the geometry concepts contained in Boti culture. The subject of this research is the Boti Dalam society which still closed to modern culture and maintain the Boti cultural traditions in daily life. The objects discussed in this research are lopo, tup mahae, tobe, and sene. The data analysis technique used in this research is taxonomic analysis. The results showed that the concepts of geometry covering the axioms of points, lines, and fields, tangent concept, the concept of area and volume of flat shapes, the concept of area and volume of space builds, and the concept of concordance. In addition, mathematical abilities such as representation, visual spatial ability, connection ability, and problem solving ability can be developed based on geometric culture of the Boti Tribe. The results of this exploration can be used by mathematics teachers to develop geometry learning in Boti culture-based classes.
