THE PROCEEDING OF THE 4^TH INTERNATIONAL CONFERENCE ON COMPUTING AND APPLIED INFORMATICS 2019

On behalf of the Organizing Committee, I am pleased to present to you the Proceeding of the 4th International Conference on Computing and Applied Informatics. This is the fourth event of the conference series organized by The Faculty of Computer Science and Information Technology, Universitas Sumatera Utara. We are honored to accept 133 outstanding works from authors from 7 different countries. Each paper has been through a challenging review process, and we would like to appreciate each of the authors that able to cooperate during the process in order to ensure the quality of each paper. With the acceptance rate of 45%, it is unfortunate for us to see that some high-quality manuscripts did not manage to go through the review process. Nevertheless, please accept our highest appreciation to every author that has participated in this event and to congratulate all of the invited authors who have their manuscript passed the process.

We would also like to give our appreciation to our keynote speakers, Prof. Putra Sumari from Universiti Sains Malaysia, Dr. Kunianingsih, SMIEEE, vice-chair of IEEE Indonesian Section, and my colleague Dr. Eng. Ade Chandra from Faculty of Computer Science and Information Technology, Universitas Sumatera Utara. It is our privilege to have such well-known scientists to share their knowledge at the conference.

Lastly, I would give my highest gratitude to all the international committee, the steering committee, and the organizing committee, who have spent countless times in the last four months. It is an honor to work alongside the current member of the committees that have repeatedly shown an outstanding effort to ensure the quality of the conference.

Thank you
