The purpose of this study was to analyze and design general physics lectures material and produce products in the form of STEM-based general physics lectures. The lecture materials are designed and made to meet scientific, technological, engineering, and mathematical aspects so that they are relevant to learning in the fields of mathematics and natural sciences. This study uses the modification of the Thiagarajan and Sammel research and development method consisting of 4 stages, namely Define, Design, Developed, and Disseminate where this research is only carried out until the development stage. The results of the research data were analyzed using quantitative and descriptive analysis techniques from expert validation data and limited trials in the form of questionnaires on respondents. The results of the validation carried out on material experts showed that the general physics equipment designed had met the criteria with a good range. Furthermore, the results of the media expert validation show that the media which is part of the lecture device that is designed is suitable for use in general physics learning with very good criteria. Similar results were seen in the results of the user response test which showed that the general physics learning material that had been designed was feasible to be used in lecture activities because general physics learning became relevant and applicable to other majors in mathematics and natural sciences.
