Pengembangan media pembelajaran fisika berbantuan javascript pada materi pokok listrik statis

. This research is motivated by the application of Industry Revolution 4.0 that demands ICT-based learning, which uses computer-based learning media specifically in the physics learning process so it makes it easy for learners to understand the concept of abstract physics. The study aims to design a physics learning media on a static electricity subject using JavaScript and verify its validity and practicality. This research is a Research and Development method developed by Borg and Gall but it is limited to only five stages. Its results are; First, JavaScript can easily be used to design a physics learning media on the subject of static electricity because the language is open source, high-level language, offering ease and flexibility. Second, results of validity analysis using the index proposed by Aiken stated that the results of the validity of Material Experts have shown an average score of "0.82" categorized as "Very High" and "0.78" on "High" category from IT/Media Experts. Third, limited result tests shown the percentage of learner's response by 86.56% on the "Excellent" category, and the educator's response obtained an average of 3.42 in the "Good" category. We concluded that "physics learning media development on the subject of static electricity using JavaScript" has successfully become a learning medium with valid and practically used as a learning medium.
