Institutional Repository UIN Sunan Kalijaga YogyakartaPENGEMBANGAN E-MODUL FISIKA BERBASIS ALAT MUSIK BUNDENGAN UNTUK MENINGKATKAN PEMAHAMAN KONSEP PESERTA DIDIK PADA MATERI GELOMBANG BUNYINIM.: 22104050036Beta Asyifa PangestuauthorConceptual understanding in physics is a crucial skill for students to grasp physics concepts, relate them to natural phenomena, and represent them in various forms. Students’ conceptual understanding can be enhanced through the use of interactive learning media, such as e-modules linked to everyday phenomena like the Bundengan musical instrument. This study aims to: 1) Determine the feasibility of a Bundengan-based physics e-module in improving students’ conceptual understanding of sound waves; 2) Determine the effect of a Bundengan-based physics e-module on improving students’ conceptual understanding of sound waves; 3) Determine the improvement in students’ conceptual understanding of sound waves. This study employed a development research design using the Borg and Gall development model. It utilized a one-group pretest-posttest design and simple random sampling. The study sample consisted of Class XI J. The data collection instrument was a 25-item multiple-choice test with explanations. The improvement in conceptual understanding was assessed by comparing students’ pretest and posttest scores. The results of the study indicate that the physics e-module based on the bundengan musical instrument that was developed is highly suitable for use as a learning medium, having achieved an average score above 4.30. The e-module has a significant effect on improving conceptual understanding. This is evidenced by the Wilcoxon test, which shows a significant difference between the average pretest and posttest scores, and based on the effect size test, a value of 3.28 was obtained, indicating that the e-module has a significant effect on improving conceptual understanding. Students’ conceptual understanding of sound wave material showed a significant increase after using the e-module. This is evidenced by the N-Gain calculation, which yielded a value of 0.78.371.33 Media Pembelajaran2026-06-02UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
