TED is an annual event that brings together the world's leading thinkers and doers to share ideas that matter in any discipline — technology, entertainment, design, science, humanities, business, and development, for example. In the spirit of "ideas worth spreading," or ideas worth sharing, TED finally formed TEDx, a self-organized local event that brings together many people to share experiences, like at TED. It is hoped that TEDx can become a forum or local forum for ideas. ideas in the community that can inspire many people to change their lives, their future and their world for the better. The success of the 2020 TEDxUniversitasAirlangga series with the theme Reversing The Stereotype, this year TEDxUniversitasAirlangga is back to be a forum for those who have the enthusiasm to share ideas and Inspirational, creative and innovative motivation under the spirit of ideas worth spreading.

This year's TEDxAirlangga University raised a grand theme, namely the Ripple Effect. It is not uncommon for people to underestimate their role in society or wherever they are, without thinking that actually, no matter how small, their role will be able to have a significant impact. A person doesn't need to have a big achievement, sometimes a small act or even an unintentional act can have a big impact. Until in the end, every impact resulting from small actions can have a big impact that you may have never thought of before. The impact resulting from small actions is a form of the Ripple Effect. 

The 2021 TEDxUniversitasAirlangga event series wants to bring a message to raise awareness that whatever people do or whatever they do will always have an impact in the future. So with the initial aim of TED being here to collect ideas and concepts, one of the series of events from TEDxUniversitas Airlangga this year will collect ideas and ideas through a Call For Essay or essay writing competition.
