The Covid-19 pandemic has changed our activities, like teaching, researching, and socializing. We are confused because we haven’t experienced before. However, as Earth's smartest inhabitants, we can adapt new ways to survive the pandemic without losing enthusiasm. Therefore, even in pandemic conditions, we can still have scientific discussions, even virtually.

The main theme of this symposium is "Reinforcement of the Sustainable Development Goals Post Pandemic" as a part of the masterplan of United Nations for sustainable development goals in 2030. This symposium is attended by 348 presenters from Indonesia, Malaysia, UK, Scotland, Thailand, Taiwan, Tanzania and Timor Leste which published 202 papers.

Furthermore, we are delighted to introduce the proceedings of the 2nd Borobudur Symposium Borobudur on Humanities and Social Sciences 2020 (2nd BIS-HSS 2020). We hope our later discussion may result transfer of experiences and research findings from participants to others and from keynote speakers to participants. Also, we hope this event can create further research network.
