Abstract

Students experience difficulties in understanding geometric geometry because the learning media used are still monotonous and do not integrate local cultural elements or digital technology. Contextual learning through ethnomathematics, particularly the utilization of the structure and ornamentation of Prambanan Temple, can help students build a more meaningful understanding (Rizki & Khaerunnisa, 2022; Yuliani et al., 2023). Contextual Teaching and Learning (CTL)-based e-LKPD is the right solution because it can encourage interactive, relevant, and student-centered learning activities (Sari & Ningsih, 2021). This study aims to design and develop an e-LKPD containing ethnomathematics of Prambanan Temple. Validity testing was conducted by two mathematics education lecturers and one junior high school teacher, with assessments covering aspects of presentation, language, appearance, media implementation, and suitability of the material with the CTL approach (Rahmawati & Putra, 2023). The validity results show that the developed E-LKPD obtained an average score of 90.3%, which is categorized as very valid and suitable for use in mathematics learning. Thus, this CTL-based E-LKPD containing ethnomathematics of Prambanan Temple can be an alternative innovative and contextual learning media for the geometry of flat shapes material for grade VIII junior high school

Abstract

Penelitian ini bertujuan untuk mengembangkan media GEMAR (Geometri, Etnomatematika, Menarik, dan Relevan) berbasis website dengan pendekatan etnomatematika budaya Klenteng Sam Poo Kong pada materi bangun ruang sisi datar. Penelitian ini merupakan penelitian pengembangan (Research and Development/R&D) menggunakan model ADDIE yang dibatasi pada tahap analysis, design, dan development. Objek penelitian ini adalah media pembelajaran GEMAR berbasis website, sedangkan subjek validasi terdiri atas tiga ahli materi dan tiga ahli media. Instrumen penelitian yang digunakan berupa angket validasi untuk menilai kelayakan media dari aspek materi maupun aspek media. Teknik analisis data menggunakan analisis deskriptif kuantitatif dengan menghitung rata-rata skor validitas media. Hasil penelitian menunjukkan bahwa media GEMAR berbasis website memperoleh skor rata-rata 3,73 dengan kategori sangat valid berdasarkan penilaian ahli materi dan skor rata-rata 3,80 dengan kategori sangat valid berdasarkan penilaian ahli media. Adapun rata-rata keseluruhan hasil validasi mencapai 3,76 dengan kategori sangat valid. Dengan demikian, media GEMAR berbasis website dinyatakan layak digunakan sebagai media pembelajaran matematika pada materi bangun ruang sisi datar.
