This research is motivated by the low level of student creativity in Fine Arts learning in elementary schools, characterized by students' limited ability to develop ideas, imagine, and produce work independently. This study aims to describe the implementation of the Project-Based Learning (PjBL) model in developing student creativity in Fine Arts learning for grade IIIB students at SD Negeri 1 Nagrak and to identify supporting and inhibiting factors. The study used a qualitative approach with descriptive methods. Data collection techniques included observation, interviews, and documentation. The study subjects consisted of 43 grade IIIB students at SD Negeri 1 Nagrak. The results showed that the application of the Project-Based Learning model to the topic of making collages from colored paper improved student creativity. Through the stages of determining fundamental questions, project planning, scheduling, project implementation, presentation of work, and evaluation, students became more active, creative, confident, and able to work well in groups. Student creativity was evident in their ability to develop ideas, select color combinations, and produce diverse and original collage designs. Supporting factors for PjBL implementation included teacher support, availability of tools and materials, student enthusiasm, and good group cooperation. The inhibiting factors include differences in student abilities, low self-confidence among some students, and limited learning time. Based on the research results, it can be concluded that the Project-Based Learning (PjBL) model is effective in developing student creativity in Fine Arts lessons in elementary schools. Therefore, this model can be used as an innovative learning alternative to increase student engagement, creativity, and self-confidence.
