This research aims to explore the role of ethnoscience learning in improving students' comprehension of concepts in the Solid-State Physics course under the framework of Independent Campus, Independent Learning (MBKM). The study involved 17 students from the Physics Education Study Program at FSTT UNDIKMA. It focused on assessing students' comprehension of concepts in the Solid-State Physics Introduction course before and after implementing ethnoscience learning. Research tools included questionnaires, observations, and interviews with students. The findings indicated a significant improvement in students' understanding of solid-state physics concepts after applying the ethnoscience approach. Before the implementation of ethnoscience learning, only 10 out of 17 students had adequate comprehension of solid-state physics concepts. However, after implementing ethnoscience learning, there was a notable increase, with 15 out of 17 students demonstrating an understanding of these concepts. Additionally, observations suggested increased active participation and involvement among students. Prior to the ethnoscience learning, most students had limited participation levels, often being passive listeners during class discussions, with minimal interaction among peers. Following the implementation of ethnoscience learning, there was a significant improvement in students' participation levels. They became more engaged in class discussions, asking questions, and providing responses to the learning material. Furthermore, interviews depicted a positive response to culturally relevant learning. The implications of this research encompass curriculum enhancements, faculty training, and further studies. Thus, ethnoscience learning in the context of solid-state physics can be considered an effective innovative method for enhancing students' conceptual understanding.
