Etnomatematika: Karakteristik Batik Bondowoso Di Rumah Produksi Ki Ronggo

Abstract

Etnomatematika adalah hubungan antara matematika dan budaya. Penelitian ini bertujuan untuk mendeskripsikan etnomatematika Batik Bondowoso. Penelitian ini menggunakan penelitian kualitatif dengan pendekatan etnografi. Subjek penelitian adalah 3 pengrajin di rumah produksi Batik Kironggo. Pengumpulan data dilakukan dengan observasi, wawancara, dan dokumentasi. Teknik analisis data yaitu dengan cara melakukan observasi lapangan kemudian memberikan beberapa pertanyaan terkait apa saja yang dilakukan oleh ketiga subjek itu di lapangan. Hasil penelitian ini menunjukkan adanya etnomatematika pada batik Bondowoso khususnya di rumah produksi Ki Ronggo berupa titik, garis, sudut, bentuk 2D (persegi, belah ketupat dan lingkaran), persamaan dan transformasi geometri (pergeseran, refleksi, rotasi dan dilatasi).

Systematic Literature Review: Ethnomathematics of Traditional Batik Motifs on Students’ Mathematical ConceptsUnderstanding Ability

“…(Fachrunnis a & Sari, 2023) The results of this study showed that Jasmine batik incorporates the concept of geometric transformation, specifically translation and rotation in the Eagle and Leaf motifs, as well as reflection in the Jasmine Flower and Leaf motifs. (Yudianto et al, 2021) The results of this study showed that the traditional Bondowoso batik pattern used geometric concepts such as congruence, points, lines, angles, and flat buildings. Additionally, the pattern also used geometric transformations in the form of translation, reflection, dilation, and rotation.…”

Exploration of Mathematical Concept in Kite Making Wau Bengkulu

“…Interestingly, craftsmen still do this activity traditionally, namely weighing knives. In geometry states that points can be described but cannot be defined and their location can be determined (Yudianto et al, 2021). In these results, a mathematical concept emerges, namely the concept of the dividing point in the weighing knife activity.…”
