Eksplorasi Konsep Matematika Pada Batik Jetis Sidoarjo Untuk Mentransformasikan Konteks Pembelajaran Matematika Di Sekolah Dasar

Abstract

Abstract:. The background of this research is based on culture and experiences of the researcher when studying mathematics during became student. As Sidoarjo citizen, researcher never had experienced studying mathematics with local culture. Integration of culture and mathematics known as ethnomathematics. One of cultures in Sidoarjo is batik Jetis. The aim of this research is to exploration mathematics concept in primary school on batik Jetis Sidoarjo. The type of this research is qualitative transformative with writing as inquiry method, postmodern interview, and literature study.The results of this research show that on the steps of the the process batik Jetis Sidoarjo there are some concepts of mathematics. The concepts of the steps berofe production are whole number, the operations of whole number, measurement, and statistics. The concepts of the production process are ordinal number, time, and geometry as straight lines, zig-zag lines, parallel, rotational symmetry, curve, triangle, rhombus, circle, rectangle, oval, fold symmetry, and reflection. Meanwhile, The concepts of after production are measurement, money, and statistic. The results of this research ultimately had an impact on changing views of researcher and teacher who previously thought that culture and mathematics had absolutely not related, changed and understood that culture and mathematics are closly related.Keyword: Batik Jetis Sidoarjo, Ethnomathematics, Transformative Abstrak: Penelitian ini dilatarbelakangi oleh kultur peneliti dan pengalaman peneliti pada saat belajar matematika selama menjadi siswa. Peneliti sebagai orang Sidoarjo tidak pernah mengalami pembelajaran yang dikaitkan dengan budaya setempat terutama dalam pembelajaran matematika. Keterkaitan budaya dan matematika dikenal dengan istilah etnomatematika. Salah satu budaya yang dimiliki oleh Sidoarjo adalah batik jetis Sidoarjo. Adapun tujuan dari penelitian ini adalah untuk mengeksplorasi konsep matematika di sekolah dasar pada batik Jetis Sidoarjo. Penelitian ini berjenis kualitatif transformatif dengan metode autoetnografi melalui writing as inquiry, wawancara semiterstruktur, dan studi literatur. Hasil eksplorasi menunjukkan bahwa pada tahapan pembuatan batik Jetis Sidoarjo terdapat konsep matematika. Pada tahap persiapan produksi terdapat konsep bilangan cacah, operasi bilangan bulat, satuan baku, dan penyajian data. Pada tahap proses produksi terdapat konsep bilangan ordinal, satuan waktu, geometri seperti garis lurus, garis zig-zag, garis sejajar, simetri putar, kurva, segitiga, belah ketupat, lingkaran, persegi panjang, oval, simetri lipat dan pencerminan. Sedangkan pada tahap pasca produksi terdapat konsep satuan panjang, mata uang, dan penyajian data mean, median, modus, grafik, dan tabel. Melalui penelitian ini dapat merubah pandangan dari peneliti dan guru di sekolah dasar yang sebelumnya matematika tidak memiliki hubungan dengan budaya, berubah bahwa matematika dan budaya memiliki kaitan yang erat.Kata Kunci: Batik Jetis Sidoarjo, Etnomatematika, Transformatif

Ethnomathematics Exploration of the Malaka Culture of the Tetun Tribe Community in Malaka Regency

“…The results of the concept findings in this study are suitable for use in learning mathematics in elementary schools. This is because learning mathematics in elementary schools is the stage of planting and introducing the simplest mathematical concepts (Sholihah et al, 2021). In addition, research can be used as an integrated cultural heritage in the development of operational curricula in educational units which will indirectly make knowledge of community culture as well as a form of cultural preservation as well as material for consideration of policy implementation in the development of the School Operational Curriculum (KOS).…”

Mathematical Literacy-Oriented Student Worksheets Using the Sidoarjo Context

“…Manoy and Purbaningrum (2021) integrates Sidoarjo batik to improve high school students' mathematical literacy. Rachmawati (2012) researches ethnomathematics in the life of the people of Sidoarjo, and study by Sholihah, Dewi, and Mariana (2021), explores mathematical concepts in Jetis Sidoarjo batik for elementary school students.…”
