This study aims to overcome the problem of vegetable waste produced at Jenggawah Market by processing it into an environmentally friendly product in the form of eco-enzyme through the STEM-based Research-Based Learning (RBL) model. This study uses a qualitative descriptive approach. This approach was chosen to describe in depth the process of integrating Research-Based Learning (RBL) with the STEM (Science, Technology, Engineering, and Mathematics) approach in making eco-enzyme and its impact on student creativity. The results of the study show that the integration of RBL-STEM has great potential in equipping students to learn about vegetable waste fermentation to produce eco-enzyme. In addition, it can also foster environmental awareness. Thus, the RBL-STEM approach is worthy of being used as a contextual learning model that is applicable and provides solutions to real problems in the surrounding environment.
