description: 21st century skills such as critical thinking are essential to help students face global challenges. However, the results of the 2018 PISA study showed that Indonesian students' scientific reasoning skills are still low. Therefore, an effective learning strategy is needed, one of which is through chemistry learning. Chemistry, as part of science, helps train critical thinking skills through analysis and problem solving based on scientific data. Hydrocarbon combustion material that is relevant to environmental and health issues is considered appropriate to be integrated with the Problem Based Learning (PBL) model based on Socio-Scientific Issues (SSI). This study aims to determine the difference in students' critical thinking skills before and after the SSI-based PBL model is applied to hydrocarbon combustion material. This type of research is quantitative pre-experimental with a pretest-posttest one group design. The research was conducted in the even semester of 2024/2025 with a sample of 30 students selected through a purposive sampling technique. The instruments used were Teaching Modules, LKPD, KBK Observation Sheets and KBK test questions. The data were analyzed descriptively using Microsoft Excel and inferentially using SPSS version 27. The results showed an increase in students' critical thinking skills after implementation, with an average score increase of 37%. Hypothesis testing showed a sig. (2-tailed) <0.001, which means there is a significant difference. In addition, the results of the non-test of KBK achievement were 89% with a very good category. Thus, the SSI-based PBL model is effective in improving students' critical thinking skills.
