Abstract

Penelitian ini bertujuan untuk 1)mengembangkan lembar kerja siswa (LKS) berbasis laboratorium virtual Physics Education Tecnology (PhET) pada materi gelombang berjalan dan gelombang stasioner, 2)mengetahui kelayakan LKS dan 3)mengetahui respon siswa terhadap LKS yang dikembangkan. Penelitian dilakukan di SMA Negeri 42 Jakarta kelas XI MIPA semester genap tahun ajaran 2020/2021. Penelitian ini menggunakan metode research and development (R&D), teknik pengambilan sampel menggunakan simple random sampling dan media yang digunakan terlebih dahulu divalidasi oleh masing-masing validator ahli. Instrumen penelitian yang digunakan yaitu angket respon siswa. Hasil validasi ahli materi pokok bahasan memperoleh nilai rata-rata 81,09% dengan kategori layak, hasil validasi ahli media memperoleh nilai rata-rata 76,96% dengan kategori layak, hasil validasi ahli bahasa memperoleh nilai rata-rata 82,50% dengan kategori sangat layak. Respon angket siswa terhadap LKS diperoleh skor rata-rata sebesar 87,39% dengan kategori sangat positif.Kata Kunci : Laboratorium Virtual PhET, dan research and development (R&D)./ This study aims to first find out how to develop student worksheets (LKS) based on a virtual physics education technology (PhET) laboratory on traveling waves and stationary waves, the second find out the feasibility of LKS and the third find out student responses to the developed worksheets. The study was conducted at SMA Negeri 42 Jakarta class XI MIPA even semester of the 2020/2021 academic year on 27 May 2021. This study used the research and development (R&D) method, the sampling technique used random sampling and the media used was first validated by each expert validator. The research instrument used is a student response questionnaire. The results of the validation of subject matter experts one obtained an average score of 81,09% in the adequate category, the results of the media expert validation obtained an average score of 76.96% in the adequate category, the validation results of linguists obtained the average score of 82.50% in the very feasible category. Student questionnaire responses to the LKS obtained an average score of 87.39% in the very positive category. Keywords : PhET Virtual Laboratory, and research and development (R&D).
