This study aims to (1) analyze students' problem-solving skills before using the results of developing interactive e-modules in PBI learning, (2) produce interactive e-modules in PBI learning that can be used as materials or tools for teachers to facilitate learning activities, (3) produce interactive e-modules in PBI learning with quality, namely interactive e-modules for PBI learning that meet valid, practical and effective criteria so that they can help students improve their problem-solving skills. The research method used an R D approach. The subject of this research was taken based on a purposive sampling technique. While the validators consisted of lecturers from the Semarang State University Postgraduate Program and 2 (two) teachers from SMP 16 Bengkulu city. Data collection was carried out through tests, observations, questionnaires, and documentation. Data analysis was performed using descriptive and inferential statistics using the Wilcoxon test.
