On behalf of the Organizing and Program Committee, we warmly welcome you to the 9th International Conference on Information and Communication Technology (ICoICT) 2021 on August 3-5th, 2021. The 9th ICoICT 2021 is jointly organized by Telkom University Indonesia, Multimedia University Malaysia, and Universitas Gadjah Mada Indonesia, in association with The IEEE Indonesia Section, The IEEE Indonesia Section Computer Society Chapter, and The IEEE Signal Processing Society Indonesia Chapter. The previous ICoICT conferences have successfully served as a forum to bring together a diverse group of people from academics and industries to share and present the latest issues and recent developments in Information and Communication Technology (ICT). Papers from the previous ICoICT 2013 until 2020 have been published in IEEE Xplore and indexed in Scopus.

The technical program of 9th ICoICT 2021 consists of eight keynotes, one knowledge transfer, five tutorials, and six tracks on "Digital Innovations for Post-pandemic Recovery." For the first time, the conference features social events that allow conference participants to meet and discuss with fellow researchers in the same field of interest. Competition for the Best Paper Award is also organized. The 9th ICoICT 2021 received 296 paper submissions from 20 countries, out of which 122 papers have been accepted - corresponding to an acceptance rate of 43.4%. All paper submissions have been subjected to a rigorous peer-review process that evaluates their significance, novelty, and technical quality. Each paper was reviewed independently by at least three experts.

Due to the COVID-19 pandemic, we have decided to hold the 9th ICoICT 2021 as a virtual conference. The organizing committee had been work hard to create a virtual conference that will be valuable and engaging for both presenters and attendees. The full conference format mixes pre-recorded and asynchronous engagement and lives engagement through Question-and-Answer (Q & A) and in-person video calls. 

The 9th ICoICT 2021 has been organized due to the work and effort of colleagues, friends, and organizations. We wish to thank all who have participated and supported our work in many ways and all who helped us make this event possible and successful. We would like to express our gratitude to the Organizing Committee and Technical Committee members and all Telkom University colleagues who assisted us in planning and organizing this conference. We also wish to thank all the reviewers who worked very hard in reviewing papers and providing suggestions for the paper's improvements. We would like to express our sincere gratitude to the Keynote and Tutorial Speakers. We would also like to thank all of the sponsoring organizations for providing their generous financial support. Last but not least, we would like to give appreciation to the authors who have submitted their excellent works to this conference and all the attendees. We appreciate your virtual attendance at the 9th ICoICT 2021. We hope you enjoy all the keynote sessions, the technical sessions, and the social events and inspire your future research.
