This study aims to develop an integrated hydrocarbon e-module based on the STEAM approach to support students’ environmental literacy. The study employed a Research and Development (R&D) methodology using the ADDIE model, limited to the analysis, design, and development stages. The research was conducted at a public senior high school in Central Java, Indonesia. The research instruments included an expert validation sheet, a readability questionnaire, and teacher and student response questionnaires. The data were analyzed descriptively by calculating the percentage of the obtained scores relative to the maximum possible scores and interpreting the results based on predetermined criteria. The developed e-module consists of interactive digital instructional materials presented in a Heyzine-based flipbook format that integrates the STEAM approach and environmental issues into hydrocarbon topics. The expert validation results yielded a score of 95.15%, categorized as “highly valid,” while the readability test yielded a score of 89%, categorized as “very good.” These results indicate that the developed e-module is suitable as an alternative digital teaching material for supporting more contextualized hydrocarbon learning and fostering students’ environmental literacy.
