Salgogram Android Digital Book for Grade XI Informatics Learning

The low understanding of students in Informatics subjects is often caused by a lack of innovation in learning media and the complexity of topics such as programming or coding, which require deep comprehension and consistent practice.This study aims to develop an Android-based learning media named Salgogram, designed to enhance students' active engagement in Informatics subjects and equipped with interesting features. The research method employed is Research and Development (R&D) using the 4D model, which consists of four stages: define, design, develop, and disseminate. The media validation was conducted by subject matter experts and media experts. The validation results show a feasibility level of 94.2% from subject matter experts and 90% from media experts, both categorized as "Very Feasible." A small group trial indicated a feasibility level of 90.2%, also categorized as "Very Feasible". Based on the research findings, the Salgogram learning media is deemed highly feasible for supporting the teaching and learning process in Informatics subjects. Highlights: Innovative Learning Media – Salgogram enhances student engagement in Informatics through an interactive Android-based platform. High Feasibility – Validation results from experts and trials indicate a feasibility level above 90%, categorizing it as "Very Feasible." 4D Development Model – The learning media was developed using the 4D model (Define, Design, Develop, Disseminate) for systematic implementation.
