<![CDATA[This study aims to describe the implementation of the Pancasila Student Profile Strengthening Project (P5) on the theme of Sustainable Lifestyle among third-grade students at SD Inpres BTN IKIP I Makassar. It also examines student responses, obstacles encountered, and the project's contribution to developing an environmentally conscious character. The study employed a qualitative case study approach, with third-grade students and their class teachers as supporting informants. Data collection techniques included observation, interviews, and documentation. The results indicate that the project's implementation aligns with the Merdeka Curriculum guidelines, encompassing the following stages: introduction to the concept of waste, contextual activities involving waste sorting practices within the school environment, an action stage involving the creation of mosaics from natural and recycled materials, and collaborative evaluation and reflection. Student responses were very positive, demonstrated by enthusiasm, active participation, and the emergence of new habits such as maintaining cleanliness and understanding the 3R principles. Technical obstacles, such as limited waste management tools and facilities, were overcome through a flexible approach by the teachers. This study concludes that the P5 project has a significant contribution in developing the character of Pancasila students, especially mutual cooperation, creativity, responsibility, and concern for the environment in grade III students.]]>
