Digital Technology Used in Character Building Education to Anticipate Radicalism: BINUS University's Contribution to Strengthen Indonesia's Defense

National defense must be able to overcome various threats that exist. It is necessary to develop national strength for national defense purposes. One of the national strengths that need to be built is human resources. Human resource development is not only related to skills and expertise, but also ideology. For Indonesia, strengthening this ideology is very important to overcome the threat of radicalism. Through National Character-Building education, BINUS University contributes to the strengthening of ideology to anticipate the threat of radicalism. Using the SAMR Digital Learning Theory approach, this paper will describe how the digital technology-based character learning model carried out by BINUS University's Character-Building Development Center (CBDC) works. During the pandemic, Binus University's Character-Building Development Center required to adapt its method to overcome this challenge through existing technology. Which the use of technology has reach the highest level, namely, redefition in the structure of the level use in SAMR model technology. Which also proves the maximization process of character learning in Binus University cannot be separated from maximizing technology integration in the learning process.The research method uses qualitative methods with data collection techniques through observation of the learning process and literature study.
