Abstract

The International Symposium of Geoscience, Oil & Gas Engineering, Sustainable and Environmental Technology (GEOSOSTEK 2020) is an international conference initiated by Hemispheres and STIEPARAPI. This conference was originally planned for an offline meeting and held in Yogyakarta, Indonesia. However, after the announcement of the COVID-19 pandemic by the World Health Organization (WHO), it resulted in many countries putting into lockdowns and travel restrictions. In Indonesia itself, the government's policies are social restrictions on a large scale and fairly strict travel regulations. In addition to many requirements such as mandatory COVID-19 swab testing and others. So that we feel quite burdensome during this Pandemic. With a long consideration, finally this conference was decided to be held virtual while still meeting conference standards through the Zoom application. This virtual conference has been held according to the set schedule, which was December 19, 2020. The papers submitted in this conference were reviewed by 3 reviewers and the results based on the decisions of the 3 reviewers. The received papers in this conference were 82 papers and only 48 papers have been accepted. The paper authors at this conference must present their papers with a duration of 15 minutes including the question and answer. Scientific discussions are maintained in this conference to meet quality conferences from paper selection to submission of conference papers to publishers. Many of the conference participants were satisfied if the conference was held in a virtual manner given the many burdensome regulations and so that they would not catch COVID-19.The rise of issues related to the COVID-19 outbreak has influenced researchers to direct their research in this area. This epidemic has become a global epidemic and has had tremendous impacts in terms of environmental, economic, food and other conditions. Not only the COVID-19 outbreak, several areas were also affected by disasters such as floods, landslides, earthquakes, and so on. These incidents reveal the fact that the world is getting old and humans should be wiser in treating it. Various policies, facilities and infrastructure were deployed to mitigate this disaster so that humans and the environment could survive and continue their lives. One example relates to the implementation of lockdown policies or restrictions on social interactions and the closure of business facilities in order to reduce the spread of the virus. On the one hand, this has an impact on the economic side of the community, but on the other hand, the environment is getting cleaner because it reduces pollution caused by vehicle waste and production waste. Various kinds of technological devices are also used to communicate over long distances in interacting so that the support of technological devices is very helpful for humans in their lives. Hopefully the coming years of this pandemic will end quickly and humans can do activities as before. We hope that the papers in this conference can be a solution in reducing the burden in facing the current pandemic and disaster.
