E-Reaction is a significant initiative undertaken by E-Radio members as part of their community service efforts. This activity aims to implement the third point of the Tridharma of Higher Education, namely community service. In the context of Sustainable Development Goal (SDG) 4, which emphasizes quality education, E-Reaction has a significant impact.

Through E-Reaction, E-Radio members actively contribute to society through various activities related to broadcasting, information, and entertainment. They can educate on relevant social, cultural, and environmental issues and provide access for the public to participate in the broadcasting process. This not only creates better understanding among the public but also improves their media literacy.

Furthermore, E-Reaction can also support SDG 4 by providing training and mentorship to young people interested in pursuing careers in the media industry. This helps create a more skilled and experienced generation in broadcasting, which in turn will contribute to improving education and the quality of broadcasting in the future.

Thus, E-Reaction is a concrete proof of E-Radio's commitment in supporting SDG 4 by engaging in community service that focuses on quality education, media literacy, and the development of potential young generations.
