Abstract
One of the efforts in changing the education system for the better is the application of learning media that supports the era of RI 4.0. Physics subjects have an important role in facing the Industrial Revolution 4.0, namely providing opportunities for students to explore knowledge through technology that suits their needs, one of the sources of technology that can be used by students is Augmented Reality (AR) technology. The purpose of the study was to design and test the validity of AR which was applied to the special rays of the lens material. The resulting product is named special rays of the lens-based Augmented Reality (SILAR). The development model used in this research is a 4-D development model (four-D Model) with the stages of Define, Design, Development, and Dissemination. The data collection technique used in this study was an assessment instrument with a questionnaire. There are 4 questionnaire assessment instruments, namely material validation questionnaires whose results are in the good category (89%), media validation questionnaires with an average of 90% (good), question validation questionnaires in the good category (89.5%).
