The laboratory is a facility that provides all kinds of equipment necessary for scientific activities. As one of the majors in the Faculty of Engineering, Universitas Negeri Surabaya, Department of Informatics Engineering (JTIF) also has several laboratories to support teaching and learning process for both students and teachers. Lots of equipment stored in the laboratory to support learning in the Department of Informatics. Because many equipment's in the laboratory, it is necessary to record inventory. The records that have been done so far are still manual using MS word or MS excel. One of the weaknesses of manual system is the possibility of missing notebooks, so lab work inventory evidence is missing. Of course, this will reduce the quality value of a laboratory and of course this is very ineffective. In this paper, we propose the application of Quick Response (QR) codes to conduct laboratory inventory. This application use framework Bootstrap which supports responsive web technology. By using the framework, the application can be accessed by mobile phone. This framework can respond to user behavior and environment based on platform size, as well as monitor screen orientation. The outcome is expected to facilitate the process of laboratory inventory in the Department of Informatics Engineering UNESA.
