Soft skills are essential factors in preparing students to face the increasingly competitive job market. However, traditional learning methods often pay less attention to the development of these non-technical skills. This study aims to analyze the impact of project-based learning integrated with STEAM (Science, Technology, Engineering, Arts, and Mathematics) on improving students' soft skills in the Organic Chemistry course, particularly in the topic of hydrocarbons. The research employs a quantitative approach with a descriptive-correlational design. The sample was selected purposively, involving 33 students who took the Organic Chemistry. Data were collected through a closed-ended questionnaire using Google Form, and the data analysis was conducted using simple linear regression. The results showed that the project-based learning method integrated with STEAM (PJBL-STEAM) had a significant impact on the development of students' soft skills, with a determination coefficient (R²) value of 0.300. This indicates that the method explains 30% of the variation in soft skills improvement, while the remaining percentage is influenced by other factors beyond this study. In conclusion, this study highlights that PJBL-STEAM is not only effective in enhancing students' technical abilities but also plays a crucial role in developing the non-technical skills required in professional settings.
