This study aims to find a model for strengthening technological literacy in junior high schools. Examining the importance of strengthening technology literacy-based blended learning in dealing with the era of the Industrial revolution 4.0. This era is built through Cyber Physical System (CPS) and Internet of Things and Services (IoT and IoS) as its main foothold. In this era of digital revolution, all information can be accessed easily and in real-time even very quickly and without limits (unlimited). The development of information technology and computer digitization has created a "new space" that is artificial and virtual (cyberspace) and even "the world is flat" the world is not limited by anything. Therefore, the phenomenon of technological progress must be positively addressed for the development and progress of human civilization, including the world of education. Strengthening Blended Learning based on technological literacy is a strategic and innovative step in preparing and designing future educational systems and patterns in the face of the culturally disrupted flow of society that continues to develop massively in the industrial era 4.0. This study uses quantitative research with survey method and a qualitative descriptive method to find a model of strengthening technological literacy by junior high school teachers. The data analysis technique was carried out based on the theory of Miles and Huberman, there were three stages of data analysis: (1) data reduction, (2) data display, and (3) data conclusion according to the researcher's interpretation. Based on the results of research that has been done related to the correlation between the implementation of online learning and technological literacy, it was found that the average value of the implementation of online learning by teachers is > 75% and the average value of technological literacy in online learning is > 75% and there is a relationship between the implementation of online learning that is teachers do on technological literacy. The implication of this research is that it can be applied to mastering technological literacy skills in online learning during learning activities. This study found a model of strengthening digital literacy through the use of e-learning. This model includes elements of communication and collaboration in the form of active participation in learning and research activities. It consists of components of individual competence in the form of usage skills, critical understanding, and communicative abilities. This research contributes to the model of strengthening technological literacy through the use of e-learning.
