THE EFFECTIVENESS OF NATURAL DYE BATIK ETHNOSCIENCE-BASED PICTURE STORY BOOKS ON ELEMENTARY SCHOOL STUDENTS' SCIENCE CONCEPT MASTERY

Abstract

This study aims to examine the effectiveness of using an Ethnoscience-based Picture Story Book focusing on natural dye Batik to improve science concept mastery among fourth-grade elementary school students. The specific science concepts addressed are "States of Matter and Their Changes" and "Parts of Plants." The study employed a Quantitative approach with a Pre-Experimental One-Group Pretest-Posttest Design. The sample consisted of 30 Grade IV students at SDN Sumurwuni, Cirebon City, selected using purposive sampling technique. Data were collected using a concept mastery test administered before (pretest) and after (posttest) the treatment. Data analysis was performed using the Paired Sample t-test and Normalized Gain (N-Gain) score. The results indicated a significant improvement in the students' average score from 60.75 to 87.75. The N-Gain analysis yielded a score of 0.69, categorizing the improvement as Medium. The visualization of the Batik process within the storybook proved effective in helping students concretize abstract science concepts. This study concludes that integrating local wisdom into visual literacy media is effective in enhancing science learning outcomes for elementary school students.
