Critical thinking is an important part of education because it helps students develop important and self-reflective skills like 1) taking in and processing information and ideas, 2) analyzing and judging reasoning, and 3) thinking about and judging their thoughts. This study scrutinizes the critical reasoning component within the framework of the Pancasila Student Profile Strengthening Project, which is associated with the Independent Learning Curriculum. Descartes' "Dubium Methodicum" serves as a theoretical framework for comprehending the cultivation of critical reasoning in students. A qualitative research method is used in this study, which combines a qualitative analysis model of documents with an interdisciplinary examination of document content. The focus is on the relevance, implications, and philosophical, methodological, and practical aspects of the different ideas and content within the documents. The results and findings show that the Pancasila Student Profile Strengthening Project's critical approach is very relevant and has important implications from Descartes' point of view. The following discussion focused on how to improve the critical thinking part of the Independent Learning curriculum through an interdisciplinary approach and changes to the way teachers teach. The Independent Learning Curriculum's focus on essential learning principles can do a lot to help raise a generation that is critical, reflective, and Pancasila-oriented.
