Abstract
Learning mathematics using a cultural approach is commonly known as ethnomatematics. Ethnomatematics is a mathematics learning approach that bridges mathematics learning through local culture. The purpose of this study was to explore the culture of Sonaf L.A.N Taolin and describe the mathematical concepts that exist in the building elements of Sonaf L.A.N Taolin. This type of qualitative research uses an ethnographic approach that aims to explore the mathematical concepts found in Sonaf L.A.N Taolin. The subject of this study was an informant, Raja Insana. The research instruments were human instruments, observation guidelines, and interview guides. Data analysis was carried out in three stages, namely data reduction, data display and conclusion drawing. The results of this study indicate that building elements such as poles, doors, and roofs from Sonaf L.A.N Taolin contain geometry concepts that can be implemented as a medium for learning mathematics on the material: flat shapes, spatial structures, similarities, geometric transformations (reflections).

Summary
Abstrak: Pembelajaran matematika dengan menggunakan pendekatan budaya biasa dikenal dengan etnomatematika. Etnomatematika merupakan pendekatan pembelajaran matematika yang menjembatani pembelajaran matematika melalui budaya setempat. Tujuan penelitian ini adalah mengeksplorasi kebudayaan Sonaf L.A.N Taolin dan mendeskripsikan konsep-konsep matematika yang ada pada unsur-unsur bangunan dari Sonaf L.A.N Taolin. Jenis penelitian kualitatif ini dengan pendekatan etnografi yang bertujuan untuk mengeksplorasikan konsep-konsep matematika yang terdapat pada Sonaf L.A.N Taolin. Subjek penelitian ini adalah informan yaitu raja Insana. Instrumen penelitian berupa human instrument, pedoman observasi, dan pedoman wawancara. Analisis data dilakukan melalui tiga tahap yaitu reduksi data, display data dan penarikan kesimpulan. Hasil penelitian ini menunjukkan bahwa unsur-unsur bangunan seperti tiang, pintu, dan atap dari Sonaf L.A.N Taolin memuat konsep geometri yang dapat diimplementasikan sebagai media pembelajaran matematika pada materi: bangun datar, bangun ruang, kesebangunan, transformasi geometri ( refleksi)
