On behalf of the Organizing Committee, it is my great pleasure to welcome you to The 2nd International Seminar of Science and Applied Technology (ISSAT 2021) with the theme “Challenges in Research and Innovation in New Normal Era”. ISSAT 2021 is an International Seminar initiated by Politeknik Negeri Bandung (Polban), and this is the second year that Polban ever holds such a big event. This year feels more special because we are accompanied with STMIK AMIK Bandung, Universitas Jenderal Achmad Yani, and Politeknik LPP Yogyakarta.

ISSAT 2021 was attended by representatives from 10 countries as presenters, keynote speakers, and organizer. We received 135 manuscripts submitted by authors from various fields. However, after going through several review processes, only 109 high-quality papers were accepted to be presented in this event.

We are honored and delighted to have three keynote speakers in ISSAT 2021 who deserve my sincere thanks, namely Professor Christopher Gan of Lincoln University New Zealand, Professor Sumeru of Politeknik Negeri Bandung Indonesia, and Associate Professor Alexander Vyboishchik of Polytechnical Institute, South Ural State University-Chelyabinsk Rusia.

ISSAT 2021 would not be how it is without the support and advice from various parties. Therefore, I would like to extend my hearty gratitude to Director, Vice Director, and Research Center&Community Services, all staff at Politeknik Negeri Bandung, and all participants for sharing and presenting their research in this seminar. Special thanks go to the scientific committee and reviewers for their valuable work. Most importantly, this conference is supported by a dedicated organizing committee and creative team who deserve my deepest thanks and highest appreciation. This seminar becomes special with the support from Atlantis Press as the publisher of the conference proceeding. I would like to take this opportunity to give sincere gratitude and the highest appreciation to Atlantis Press, and all sponsors that cannot be mentioned one by one for their incredible supports.
