Penelitian ini dilatarbelakangi oleh lkpd yang digunakan guru masih bersifat konvensional dan belum banyaknya keterampilan proses sains terintegrasi dilatihkan pada peserta didik saat pembelajaran fisika. berdasarkan observasi awal yang dilakukan diperoleh keterampilan proses sains peserta didik tergolong kategori rendah dan minimnya praktik langsung karena keterbatasan fasilitas laboratorium fisika. tujuan penelitian ini adalah mengembangkan lkpd berbasis virtual lab untuk meningkatkan keterampilan proses sains peserta didik. metode yang digunakan dalam penelitian ini adalah penelitian pengembangan (r&d) dan mengacu pada model pengembangan addie. desain penelitian lkpd menggunakan pretest dan posttest control group design. sampel yang digunakan adalah kelas xi f-6 berjumlah 35 peserta didik sebagai kelas eksperimen dan kelas xi f-5 berjumlah 35 peserta didik sebagai kelas kontrol di sma n 1 kota langsa. hasil rata-rata uji kevalidan lkpd sangat tinggi sebesar 0,97, memiliki tingkat kepraktisan 80,16% dengan kategori tinggi dan skor rata-rata sebesar 112,23 dari segi kemenarikan, isi dan kemudahan, serta lebih efektif dalam meningkatkan keterampilan proses sains peserta didik terlihat dari hasil perbedaan peningkatan ngain antara kelas eksperimen sebesar 0,70 kategori tinggi dengan kelas kontrol sebesar 0,53 kategori sedang. berdasarkan analisis uji one way anova menggunakan spss dapat disimpulkan bahwa terdapat peningkatan keterampilan proses sains peserta didik yang diajarkan menggunakan lkpd berbasis virtual lab dan memiliki validitas sangat tinggi sehingga layak digunakan dalam pembelajaran fisika.

This study was motivated by the fact that the worksheets used by teachers are still conventional and that there is a lack of integrated science process skills being taught to students during physics lessons. Based on initial observations, it was found that students' science process skills were classified as low and that there was a lack of hands-on practice due to limited physics laboratory facilities. The purpose of this study was to develop virtual lab-based worksheets to improve students' science process skills. The method used in this study is research and development (R&D) and refers to the ADDIE development model. The LKPD research design uses a pretest and posttest control group design. The sample used is class XI F-6 with 35 students as the experimental class and class XI F-5 with 35 students as the control class at SMA N 1 Kota Langsa. The average validity test score for the LKPD was very high at 0.97, with a practicality level of 80.16% in the high category and an average score of 112.23 in terms of attractiveness, content, and ease of use. Additionally, it was more effective in improving students' scientific process skills, as evidenced by the difference in N-gain improvement between the experimental class (0.70, high category) and the control class (0.53, moderate category). Based on the One-Way ANOVA analysis using SPSS, it can be concluded that there is an improvement in students' science process skills taught using LKPD based on virtual labs, which have very high validity and are therefore suitable for use in physics education
