Technology is the result of the process of scientific development. 21st century technology has developed rapidly in the scope of education. High-level thinking is an important competency for students in the 21st century. For this reason, learning planning is needed that is able to improve high-level thinking competencies, especially in terms of student interpretation. Many practical lessons at SMA N 1 Balapulang are still not technology-based. This research aims to produce a practical tool based on Arduino UNO to improve graphic interpretation for high school students. This type of research is Research and Development (R & D) and uses a research model, namely ADDIE (Analysis, Design, Development, Implementation, Evaluation). Based on validation by tool experts, it was found that the practical tool media developed received a score of 92.5% in the very good category. The characteristics of the media developed are the Arduino UNO microcontroller with an LM35 sensor to read the temperature of the liquid being measured, the interface of the Arduino UNO is PLX-DAQ software so that it is stored in MS Excel, there is a LKPD developed to make it easier for students during practicum. The results of improving student graphic interpretation seen from the pre-test and post-test obtained an average score from 57.11% to 89.61%. The N-Gain value obtained was 0.72, where there was an increase in graphic interpretation for students in the high category. The results of the analysis of heat change calculations proportional to temperature changes can improve student interpretation of graphs.

Penelitian ini berfokus pada pengembangan modul praktikum interferensi gelombang bunyi dengan bantuan perangkat lunak Visual Analyser dengan model pembelajaran inkuiri terbimbing. Tujuan penelitian ini adalah untuk mengetahui karakteristik dan kelayakan modul praktikum yang dikembangkan serta pengaruh penggunaan modul dapat mengembangkan keterampilan membaca grafik dan pemahaman konsep interferensi gelombang bunyi. Metode penelitian yang digunakan adalah pengembangan model ADDIE  dengan responden yaitu mahasiswa jurusan fisika UNNES yang menempuh mata kuliah gelombang yang dilakukan melalui perkuliahan daring Zoom. Hasil dari penelitian ini berdasarkan valisadi ahli materi, media, dan bahasa mendapatkan kategori layak, sedangkan berdasarkan angket responden menunjukan ketertarikan yang tinggi dengan kategori sangat layak. Penggunaan modul menunjukkan pengaruh berupa peningkatan pemahaman konsep serta mempermudah responden dalam mengembangkan keterampilan membaca grafik interferensi dan superposisi gelombang bunyi. Sehingga dapat disimpulkan bahwa modul praktikum interferensi gelombang bunyi berbantuan Visual Analyser yang dikembangkan layak untuk digunakan dan selanjutnya dapat dikembangkan untuk digunakan di tingkat universitas maupun sekolah.
