However, based on observations at SMA Kolombo, the utilization of technological facilities in physics learning has not been optimal, and students still experience difficulties in understanding the concepts of temperature and heat. Therefore, this study aims to develop an E-LKPD on temperature and heat based on Problem Based Learning assisted by PhET simulation, determine the quality of the product, students’ responses, and changes in students’ conceptual understanding after using the E-LKPD. This study employed a research and development (Research and Development) method using the ADDIE model, which consists of the stages of analysis, design, development, implementation, and evaluation. The developed product was an E-LKPD on temperature and heat based on Problem Based Learning assisted by PhET simulation, equipped with PBL-based activities, learning materials, PhET simulation in the investigation activity, exercises, games, reflection, and evaluation. To determine changes in conceptual understanding, a one-group pretest-posttest design was employed involving 27 eleventh-grade students at SMA Kolombo. The results showed that the quality of the E-LKPD obtained an average score of 3.71, categorized as Very Good, based on assessments by media experts, material experts, and a physics teacher as a practitioner. The responses of 27 students to the use of the E-LKPD obtained an average score of 0.94, categorized as Agree. The pretest and posttest results showed an increase in students’ conceptual understanding after participating in learning using the E-LKPD, indicated by an increase in the average score from 53.6 to 84.5, with an N-Gain score of 0.712, categorized as high. The increase occurred after students participated in a series of learning activities consisting of problem presentation, discussion, investigation, exercises, and evaluation. Thus, there was an increase in students’ conceptual understanding after participating in learning using the E-LKPD based on Problem Based Learning assisted by PhET simulation on the topic of temperature and heat.530.7 Pendidikan Fisika2026-08-13UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS ILMU TARBIYAH DAN KEGURUANThesis
