DESAIN AKTIVITAS PEMBELAJARAN MATERI HUBUNGAN ANTAR SATUAN BAKU BERAT BERBASIS RME MELALUI BUDAYA LELANG BANDENG DI SEKOLAH DASAR

LEARNING DESIGN OF THE RELATIONSHIP BETWEEN STANDARD UNITS OF WEIGHT BASED ON RME THROUGH MILKFISH AUCTION CULTURE IN ELEMENTARY SCHOOL

Desain pembelajaran berbasis Realistic Mathematics Education (RME) merupakan solusi efektif untuk mengatasi masalah pemahaman konseptual matematika di tingkat SD karena pendekatannya yang berbasis pada konteks realistik. RME yang berbasis etnomatematika seperti pada penelitian yang mengangkat lelang bandeng Sidoarjo ini tidak hanya memperdalam pemahaman konsep matematika, tetapi juga menghargai dan melestarikan kearifan lokal yang ada.  Penelitian  ini memiliki tujan untuk mengetahui desain aktivitas dan  respon kognitif peserta didik  dalam pembelajaran materi hubungan antar satuan baku berat berbasis RME melalui budaya lelang bandeng di kelas 3 Fase B. Penelitian ini merupakan penelitian kualitatif dengan metode design research yang terdiri dari tiga tahapan, yakni preparing for the experiment, experimenting in the classroom dan juga conducting retrospective analysis. Pengumpulan data dilakukan melalui observasi, wawancara dan dokumentasi dengan peserta didik kelas 3C SD Khadijah 3 Surabaya sebagai subjek penelitian dengan analisis retrospektif sebagai teknik analisis data yang digunakan. Hasil penelitian menunjukkan jika desain aktivitas pembelajaran mengalami penyesuaian dan respon kognitif peserta didik menunjukkan hasil yang baik. Saran terkait penelitian selanjutnya diharapkan dapat menambahkan nilai-nilai baik yang ada pada budaya lelang bandeng, penyempurnaan ilustrasi dan replika bandeng serta peningkatan efisiensi waktu pengerjaan.

Learning design based on Realistic Mathematics Education (RME) is an effective solution to overcome the problem of conceptual understanding of mathematics at the elementary level because the approach is based on a realistic context. RME based on ethnomathematics as in this study which raised the Sidoarjo milkfish auction does not only deepen understanding of mathematical concepts, but also appreciates and preserves existing local wisdom. This study has a goal to determine the design of activities and cognitive responses of  students in learning the material of the relationship between standard units of weight based on RME through the culture of milkfish auction in class 3 Phase B. This research is qualitative research with design research method which consists of three stages, namely preparing for the experiment, experimenting in the classroom and also conducting retrospective analysis. Data collection was conducted through observation, interview and documentation with students of class 3C SD Khadijah 3 Surabaya as the research subject with retrospective analysis as the data analysis technique used. The results of the study show that the design of learning activities has been adjusted and the cognitive response of students shows good results. Suggestions related to further research are expected to add good values that exist in the culture of milkfish auction, refining illustrations and milkfish replicas and increasing the efficiency of processing time.
