Pengembangan Buku Petunjuk Kinerja Siswa MA/ SMA Kelas XI Berbasis Phet Interactive Simulation Sebagai Sumber Belajar Mata Pelajaran Fisika Pada Materi Fluida Dinamis

The aims of this research were to develop the student worksheet for class XI MA/ SMA based on PhET Interactive Simulation about dynamic fluid as a source of student learning and determine the validity level and student responses for it. The type of this research was Research and Development (R&D), consisted of four stages, they were preliminary study, product development, assessment and limited test of product, and evaluation of product. The research subjects consisted of three expert judgements (material expert, media expert, and learning partitioner) as well as 46 physic students at SMAN 1 Rejotangan. The results of preliminary study showed that more than 95% of respondents were unfamiliar with PhET application and agree with made of the student worksheet, so the student worksheet based on PhET Interactive Simulation about dynamic fluid was developed. The results of material expert, media expert, and learning partitioner validation recpectively were 79.58% (valid), 82% (extremely valid), and 85.83% (extremely valid) and appropriate for used. The results of product evaluation by 46 respondents showed positive responses, namely 75% respondents stated that the work steps of the student worksheet based on PhET Interactive Simulation about dynamic fluid were clear and attractive, so it could be used easily.  Penelitian ini bertujuan untuk mengembangkan buku petunjuk kinerja siswa MA/ SMA kelas XI berbasis PhET Interactive Simulation pada materi fluida dinamis sebagai sumber belajar siswa serta mengetahui tingkat validitas dan respon siswa terhadap buku petunjuk kinerja siswa berbasis PhET Interactive Simulation tersebut. Jenis penelitian ini adalah Research and Development (R&D), terdiri dari empat tahapan yaitu studi pendahuluan, pengembangan produk, penilaian dan uji produk terbatas, serta evaluasi produk. Subjek penelitian terdiri dari tiga orang expert judgement (ahli materi, ahli media, dan praktisi pembelajaran) serta 46 peserta didik mata pelajaran Fisika di SMAN 1 Rejotangan. Hasil studi pendahuluan menunjukkan bahwa lebih dari 95% responden belum mengenal aplikasi PhET dan setuju dengan penyusunan buku petunjuk kinerja siswa, sehingga dikembangkan buku petunjuk kinerja siswa berbasis PhET Interactive Simulation materi fluida dinamis. Hasil validasi ahli materi, ahli media, dan praktisi pembelajaran masing-masing diperoleh persentase sebesar 79.58% (valid), 82% (sangat valid), dan 85.83% (sangat valid) serta dinyatakan layak untuk digunakan. Hasil evaluasi produk oleh 46 responden menunjukkan respon positif yaitu 75% responden menyatakan bahwa langkah kerja pada buku kinerja siswa berbasis PhET Interactive Simulation pada materi fluida dinamis tersebut jelas dan menarik sehingga dapat digunakan dengan mudah
