Abstract

memfasilitasi pemahaman konsep bangun ruang sisi datar, khususnya kubus dan balok kelas VII SMP, serta menilai kevalidan dan kepraktisannya untuk digunakan dalam pembelajaran. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan model pengembangan ADDIE yang meliputi lima tahapan, yaitu analisis (analysis), perancangan (design), pengembangan (development), implementasi (implementation), dan evaluasi (evaluation). Penilaian produk didasarkan pada hasil validasi oleh ahli materi dan bahasa, ahli media, serta uji coba kepada guru dan siswa terhadap E-LKPD yang dikembangkan. Hasil validasi dari ahli materi dan bahasa menunjukkan persentase kevalidan sebesar 95%, sedangkan validasi ahli media memperoleh persentase sebesar 85%. Kedua validasi tersebut menunjukkan kategori yang sangat valid, sehingga proses penelitian berlanjut pada uji coba pengguna. Subjek uji coba dalam penelitian ini melibatkan guru dan peserta didik kelas VII dan VIII di SMP Negeri 175 Jakarta. Hasil uji coba kepada guru memperoleh persentase sebesar 91,5%. Sementara hasil uji coba kepada siswa memperoleh persentase sebesar 87%. Berdasarkan keseluruhan hasil penilaian tersebut, diperoleh persentase rata-rata sebesar 90% yang termasuk dalam kategori sangat valid dan praktis. Produk akhir dari penelitian ini berupa E-LKPD berbasis STEM untuk memfasilitasi pemahaman konsep kubus dan balok yang dapat diakses pada tautan https://activepresenter.online/mod/scorm/view.php?id=12848. Dengan demikian, dapat disimpulkan bahwa produk yang dikembangkan telah memenuhi aspek kevalidan dan kepraktisan, sehingga dapat dimanfaatkan oleh siswa kelas VII sebagai media dalam mempelajari materi kubus dan balok, serta turut dalam membantu memfasilitasi pemahaman konsep kubus dan balok dengan pendekatan STEM. Kata kunci ADDIE, Bangun Ruang Sisi Datar, E-LKPD, Pemahaman Konsep, STEM. This study aims to develop a STEM-based Electronic Student Worksheet (E-LKPD) to facilitate the understanding of solid geometry, especially cube and cuboid concepts among seventh-grade junior high school students and to evaluate its validity and practicality for classroom implementation. The research employed a Research and Development (R&D) approach using the ADDIE development model, which consists of five stages: analysis, design, development, implementation, and evaluation. The assessment of the product was based on validation results from material and language experts, media experts, as well as trials involving teachers and students who used the developed E-LKPD. The validation conducted by material and language experts yielded a validity percentage of 95%, while the media expert validation obtained a percentage of 85%. Both results indicated a “highly valid” category, allowing the research to proceed to the user testing phase. The user test subjects consisted of teachers and students from seventh and eighth grades at SMP Negeri 175 Jakarta. The results of teacher testing obtained a percentage of 91.5%, whereas the student testing produced a percentage of 87%. Based on the overall evaluation results, the average validity and practicality percentage was 90%, which falls into the “highly valid and practical” category. The final product of this research is a STEM-based E-LKPD designed to facilitate the understanding of cube and cuboid concepts, which can be accessed through a provided link https://activepresenter.online/mod/scorm/view.php?id=12848. Therefore, it can be concluded that the developed product has met the validity and practicality criteria, making it suitable for use by seventh-grade students as a learning medium for cube and cuboid materials while supporting concept understanding through the STEM approach. Keywords. ADDIE, Conceptual Understanding, E-LKPD, Solid Geometry, STEM.
