This study aims to develop a web-based physics learning media with the Problem Based Learning (PBL) model in the Basic Physics course I and to find out how effective the web-based learning media are with the Problem Based Learning model in Basic Physics I. This research is a Research and Development with a development model from Borg & Gall. The results of the material validator were 80.5% of the content quality, aspects of material language usage 83%, the visual appearance of material 85%, Sound Aspects of the Material 83%, Ease of use of material 90%, 84% Problem-Based Learning Model with eligibility criteria 84, 3%. The assessment category is "very feasible", this means that website-based physics learning media with the Problem Based Learning model are by the learning material and are suitable for use in learning. The results of the media validator are 86% media effectiveness and efficiency, reliable from the media 83%, Media content is 87%, Ease of media use is 85%, Accuracy of 85% authoring tools, Media compatibility 83%, Media Integration 85%, Media documentation 82%, Media consistency 80%, with media eligibility criteria of 84%. The assessment category is "very feasible", product trials include small groups and field trials on Problem Bases Learning-based website learning media obtained that the learning media is feasible to use with details of the results of small group trials conducted obtained at 86%. Based on the results of field trials conducted obtained by 89%. It means that the website-based physics learning media with the Problem Based Learning model is by the learning media and is suitable for use in learning.
