Abstract
The research is motivated by the fact that the teaching materials used by teachers in physics instruction are still in the form of reading materials and printed student worksheets. The application of the learning model and the integration of technology in physics worksheets has not yet reached an optimal level. This research aims to develop a PBL-based electronic student worksheets on valid alternative energy materials. The type of research used is R&D with the ADDIE development model. The research instruments were in the form of teacher questionnaires, student questionnaires and validity instruments. Validity tests were carried out by 3 UNP physics lecturers. The results of product validity were obtained from the analysis of a validity questionnaire of 88.5% with great validity. The study's result is that electronic student worksheets, which is based on PBL, has very valid alternative energy materials
