Etnomatematika Pada Kerajinan Anyaman Masyarakat Dayak Kenyah (Dibimbing oleh Jero Budi Darmayasa, dan Alfian Mucti). Penelitian ini bertujuan untuk mengetahui unsur matematika yang ada di dalam kebudayaan Anyaman Dayak Kenyah dan mengetahui pandangan siswa apabila kebudayaan Anyaman masyarakat Dayak Kenyah dijadikan rangkuman materi matematika berbasis budaya dalam pembelajaran matematika di sekolah. Jenis penelitian yang digunakan yaitu penelitian kualitatif. Pendekatan yang digunakan pada penelitian ini yaitu pendekatan studi kasus. Peneliti melakukan wawancara, observasi, dokumentasi, dan mempersiapkan instrumen pengumpulan data. Kemudian setelah peneliti memperoleh data yang diinginkan peneliti melakukan pemeriksaan keabsahan data melalui perpanjangan pengamatan, peningkatan ketekunan dalam penelitian, triangulasi, diskusi dengan teman sejawat, analisis kasus negatif, member check dan penarikan kesimpulan. Adapun unsur matematika yang ditemukan dalam penelitian ini yaitu persegi, belah ketupat, pencerminan, pola bilangan, sistem koordinat kartesius, simetri, bilangan asli, sudut lancip, garis sejajar, pola bilangan, aritmatika sosial dan sistem persamaan linear dua variabel (SPLDV). Selain itu, tanggapan siswa SMP jika etnomatematika Anyaman Dayak Kenyah dijadikan pembelajaran matematika berbasis budaya di sekolah yaitu mereka merasa lebih mudah dalam memecahkan latihan soal yang diberikan ketika menggunakan etnomatematika pada pembelajaran di sekolah.

Ethnomathematics in the Woven Crafts Made by Dayak Kenyah People (Supervised by Jero Budi Darmayasa and Alfian Mucti). This research aimed to figure out the mathematical elements existing in the weaving culture belonging to Dayak Kenyah people and to uncover the students’ views on the Weaving culture of Dayak Kenyah people when used as summaries of the cultural-based mathematical materials at school. Thus, to obtain the research data, the researcher conducted interviews, observation, and documentation as well as prepared the data collection instruments. After obtaining the related data, the researcher then checked the data validity through the extended observations, increased persistence in research, triangulation, discussions with colleagues, negative case analysis, member checking, and conclusion drawing.The mathematical elements found in this study are square, split ketupat, mirroring, number patterns, cartesius coordinate system, symmetry, natural numbers, taper angles, parallel lines, number patterns, social arithmetic and a system of two-variable linear equations (SPLDV). In addition, the response of junior high school students if ethnomamatics Anyaman Dayak Kenyah used as culture-based math learning in school is that they find it easier to solve the problem exercises given when using ethnomamatics in learning in school.
