<![CDATA[Science learning in Indonesian educational institutions is often irrelevant and disconnected from the local cultural wealth. In fact, the implementation of the Merdeka Curriculum in Social Sciences (IPAS) subjects requires an integrated approach that is appropriate to the students' environment. Ethnoscience, which is research that connects modern scientific knowledge with local wisdom, presents a strategic solution to meet this need. This study aims to analyze ethnoscience-related research in Indonesia with the goal of mapping the IPAS concepts contained within and evaluating their impact on improving student learning outcomes. The method used in this research is a Systematic Literature Review (SLR), analyzing 10 scientific articles (2 international journals indexed by Scopus and 8 national journals accredited by SINTA) published between 2020 and 2025. The analysis shows that the application of ethnoscience in IPAS learning is significantly able to improve student learning outcomes. Important findings indicate that ethnoscience makes the learning process more meaningful and contextual, enhances cognitive concept understanding, and sharpens higher-order thinking skills (HOTS) and science literacy. Furthermore, the application of ethnoscience is proven effective when combined with models such as Project-Based Learning (PjBL) and STEM, as well as through the development of teaching materials like e-modules. It can be concluded that ethnoscience plays a vital role in supporting the implementation of the IPAS curriculum, not only to increase academic achievement but also to foster students' appreciation for local culture as a source of scientific knowledge.]]>
