The low level of learning independence, students' problem-solving abilities, and instructional materials that do not yet use digital as a demand for 21st century learning inspire this research. The goal of this study is to create a valid and useful Problem Based Learning based E-Module on data display and measurement material. Data centralized. This is development research (Research and Development/ R&D) employing the Plomp development paradigm. This development strategy employs two stages: preliminary research and prototyping. The subjects of this study were nine SMAN 13 Padang class X students. Observation sheets, interview guides, and questionnaires were employed as study instruments. Techniques for data analysis employ quantitative and qualitative analysis. The E-Module's validity based on problem-based learning was 89.85%, with a very valid category. The E-Module's practicality results were 87.33% in the extremely practical category. Based on the findings, it is possible to infer that the E-Module based on problem-based learning on data presentation material and data concentration measurements at SMAN 13 Padang is valid and practical, and that it may be utilized as teaching material.
