description: The inclusion of KPS in learning activities can train student’s abilities to solve scientific problems they encounter, can be developed using a learning model that actively involves students and provides them with opportunities to experiment, the STEM-PjBL learning model. This study aims to determine the differences before and after the implementation of the STEM-PjBL learning model in improving KPS on the topic of carbon footprint. This research uses a quantitative pre-experimental with a one group pretest-posttest design. The sample consisted of 33 students from class XII-Chemistry 1 at SMAN 6 Kota Serang, selected using a purposive sampling technique. This research employed several instrument, including teaching modules, student worksheets (LKPD), and KPS test questions. Data were analyzed descriptively using Microsoft Excel and inferentially using validity tests, reliability tests, normality tests, and paired sample t-test for hypothesis using the IBM SPSS Statistic 25. The study successfully demonstrated a significant difference before and after the implementation of the STEM-PjBL learning model to improve KPS on the topic of carbon footprint with a sig.(2-tailed) value of 0.000 in the hypothesis test. In addition, there was a 37% increase in the average test score percentage. Observation sheets also showed an overall average percentage of 86% the “very good” category.
