Student learning outcomes on renewable energy remain a concern because conventional teaching materials and teacher-centered learning activities may limit students’ opportunities to develop deeper conceptual understanding and active engagement. Therefore, innovative learning materials are needed to encourage students to analyze real-world problems and construct meaningful knowledge. This study investigated the learning outcomes of students in experimental and control classes ; it also examined the effect of a Deep Learning-based Student Worksheet (LKPD) integrated with the Problem-Based Learning (PBL) model on learning outcomes related to renewable energy at SMA Negeri 15 Medan. This study employed a quantitative approach with a Nonequivalent Control Group Design. Purposive sampling was used to select Class X-1 as the experimental group and Class X-4 as the control group. Although each class initially consisted of 34 students, only 30 students from each class completed all stages of the study ; thus, the final sample consisted of 60 students. The research instrument comprised 10 validated essay questions designed to measure higher-order thinking skills at cognitive levels C4–C6. Data were analyzed using normality tests, homogeneity tests, Paired Samples t-tests, and Independent Samples t-tests with IBM SPSS Statistics version 32. The results showed a significant difference between pre-test and post-test scores in both the experimental and control classes, with significance values (Sig. 2-tailed) of less than 0.001. The Independent Samples t-test also revealed a significant difference in post-test scores between the two classes (Sig. 2-tailed < 0.001). The experimental class achieved a higher mean post-test score (59.90) than the control class (39.73). These findings indicate that the use of a Deep Learning-based LKPD integrated with the PBL model had a positive effect on student learning outcomes related to renewable energy at SMA Negeri 15 Medan.
