Understanding how to work in a chemical laboratory involving instruments is important for students in doing their research. Therefore, we need an effort to make students capable of operating certain fundamental instruments in a chemistry laboratory. This study aims to produce QR Code-based instructional website to introduce chemical instruments and assess the feasibility of the media. This is a research and development (R & D) employing a model of ADDIE. The subjects were 18 students who enrolled the course of chemical laboratory management at a state university in Aceh, Indonesia. Data were obtained from questionnaires and a system usability scale instrument. The website containing pH meter, Evaporator, UV-Vis spectrophotometer, refractometer and Oven. The validation score of abovementioned features was 94.33%, 95.83%, 93.5%, 95.16% and 94.16% respectively. The validation score of the websites was 95%. The SUS Score for the web-based media QR-code was 83.75%. The QR-Code as a web-based media is very feasible to use.
