Etnomatematika: Eksplorasi Konsep Geometri pada Kerajinan Keramik Dinoyo
Keywords:
etnomatematika, geometri, keramik Dinoyo, prisma segi enamAbstract
Penelitian ini bertujuan mengeksplorasi konsep geometri yang terdapat pada kerajinan keramik Dinoyo, Kota Malang. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan metode etnografi. Data dikumpulkan melalui observasi langsung terhadap motif dan bentuk keramik, wawancara semi-terstruktur dengan pengrajin berpengalaman, dokumentasi visual, dan literatur yang relevan. Hasil penelitian mengidentifikasi sebuah pot bunga berbentuk prisma segi enam beraturan dengan sisi alas 4 cm dan tinggi 5,5 cm. Analisis geometri menunjukkan kesesuaian bentuk dengan sifat-sifat segi enam beraturan, yang digunakan untuk menghitung keliling, luas alas, luas permukaan, dan volume secara teoretis. Perhitungan ini diverifikasi melalui metode pengukuran empiris sederhana, seperti pengisian air. Temuan penelitian menunjukkan bahwa artefak keramik dapat menjadi media pembelajaran kontekstual yang menghubungkan dunia konkret dan abstraksi matematika, sekaligus mengembangkan keterampilan berpikir kritis, literasi numerik, dan pemahaman konsep geometri siswa.
