Every year, on February 13th, the world celebrates World Radio Day, a commemoration initiated by UNESCO in 2011. This day is not only to remember the existence of radio as one of the most important technological innovations of the 20th century but also to appreciate the vital role of radio in shaping modern society.

As one of the electronic communication media, radio is capable of reaching and moving all layers of society. Radio can be found in almost every place, and even some mobile phones used to have a radio feature that could be easily accessed. The strength of radio lies in its ability to convey audio messages that evoke emotions and thoughts.

One historical evidence of radio's important role can be seen in its use during the Pacific War, where Japan used radio to disseminate information about invasions and boost the morale of troops. Another example is in Indonesia, when radio was used to broadcast the Proclamation of Indonesian Independence on August 17, 1945. Through these cases, it can be seen that radio is not just an intermediary for disseminating information but also a societal mobilizer.

Today, the advancement of information and communication technology has provided accessibility to all segments of society, promoting diversity of voices and becoming an irreplaceable source of education and entertainment.

Radio, which previously could only be heard through certain stations with limited range, is now accessible to all. In fact, people can now create their own radio channels without needing complex equipment such as transmitters and antennas. In this modern era, with the help of a good internet network and simple devices like microphones or smartphones that can record audio and video, anyone can become a broadcaster.

To support the development of innovative and creative students, Universitas Dian Nusantara (UNDIRA) provides a Radio Laboratory as a learning and practice facility. This lab allows students to learn how to use broadcasting equipment and hone their communication skills through various UNDIRA radio programs. The Communication Studies Program at UNDIRA also equips students with basic knowledge of broadcasting techniques and journalism, preparing them to enter the media industry.

Radio UNDIRA is available in the form of an Android application that can be downloaded by UNDIRA's academic community and the general public. Through this application, listeners can access various information about UNDIRA, including academic programs, campus activities, as well as other inspirational and educational content.
