Abstract

Permasalahan dalam pembelajaran matematika di sekolah adalah kurangnya keterkaitan antara materi yang diajarkan dengan realitas kehidupan sehari-hari siswa, sehingga membuat pembelajaran terkesan abstrak dan kurang bermakna. Salah satu pendekatan yang dapat ditawarkan untuk menjembatani kesenjangan ini adalah integrasi etnomatematika, yaitu praktik matematika yang tumbuh dari budaya lokal, ke dalam pembelajaran sebagai pendekatan kontekstual. Penelitian ini bertujuan untuk mengeksplorasi bentuk-bentuk praktik etnomatematika yang muncul dalam aktivitas jual beli pedagang jajanan tradisional di Kabupaten Aceh Timur, khususnya di wilayah Idi Rayeuk yang merepresentasikan karakteristik sosial-ekonomi masyarakat secara umum. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan teknik pengumpulan data melalui observasi langsung dan wawancara terhadap lima pedagang yang dipilih secara purposive. Analisis data dilakukan dengan menggunakan model analisis interaktif Miles dan Huberman, melalui tahapan reduksi data, penyajian data, serta penarikan dan verifikasi kesimpulan. Hasil penelitian menunjukkan bahwa para pedagang menerapkan berbagai strategi matematis kontekstual, seperti pembulatan harga, aritmetika mental dalam menghitung total belanja, pemberian uang kembalian secara bertahap, serta pemecahan masalah saat menghadapi keterbatasan uang pecahan. Keseluruhan aktivitas ini mencerminkan praktik etnomatematika yang berbasis pengalaman dan kebutuhan praktis, serta menunjukkan adanya pemahaman matematis yang berkembang secara alami. Dengan demikian, praktik jual beli tradisional memiliki potensi besar untuk dijadikan sumber pembelajaran matematika yang relevan, bermakna, dan mendukung penguatan integrasi budaya lokal dalam pendidikan formal.

Abstract

The circulatory system is a material that is considered difficult to understand because it is impossible to directly see the organs and processes that make it up. Interactive multimedia acts as a learning tool. This research aims to create interactive multimedia facilities based on educational games that can be used as learning aids. This research uses the Multimedia Development Life Cycle (MDLC) Method. The stages in this research consist of Concept, Design, Material Collecting, Assembly, Testing, and Distribution. To determine its validity, the media is validated by media experts and material experts using an instrument in the form of a media suitability validation questionnaire. Aspects measured for material validity include aspects of suitability of content, aspects of suitability for use, aspects of appearance and language, aspects of presentation, and aspects of benefits. Meanwhile, media validity includes aspects of design layout, typography, illustration images, audio, presentation, use and navigation. The research results show that the average validation score for material experts is 95% to 98% and the average score for media experts is 91% to 93%. Overall the average for both is 91% to 98% and is classified as very good.Meanwhile, the results of testing on student respondents obtained a validity value of 91.48% in the very good category and managed to get a reliability result of 0.737 and can be said to be reliable. So, it is concluded that this interactive multimedia based on educational games is suitable for use as learning media in class XI SMA on the Circulatory System material.
