Identification of Scientific Knowledge in the Making Process of Batik Tanah Liek as Teaching Materials in Ethnoscience-Based Learning

Minangkabau Batik Tanah Liek stands out among Indonesian batiks for its unique use of natural coloring materials derived from clay and specific plants.This study aims to identify and analyze the scientific concepts embedded in the production of Batik Tanah Liek for developing ethnoscience-based teaching materials.Employing a qualitative descriptive approach, the research utilizes the Educational Reconstruction Model (MER) to explore its ethnoscientific content.Data were gathered through interviews, observations, and field notes from three batik centers in West Sumatra.The findings reveal various science concepts in the processes of production, coloring, and waste management of Batik Tanah Liek.Indigenous knowledge of the local community was reconstructed into scientific concepts related to physics, chemistry, and biology, forming the basis of ethnoscience content.These findings demonstrate the potential to develop ethnoscience-based teaching materials suitable for elementary to high school levels.Such materials align with the Science Learning Outcomes of the Merdeka Curriculum, fostering the Pancasila Learner Profile.
