Preface Lekantara Annual Conference on Engineering and Information Technology (LiTE)

Lentera Akademika Nusantara (Lekantara), an Indonesian scientific publisher, organized Lekantara Annual Conference on Engineering and Information Technology (LiTE) on November 30, 2021 held fully virtual. The conference aims to exchange knowledge and research finding among academicians, researchers, professionals, policy makers, and postgraduate students. The Awareness to increase the number of publications on the results of research that has been done deserves appreciation from all parties. Thus, Lekantara provides motivation and space for researchers to disseminate their research and accommodate their results of research. Lekantara Annual Conference on Engineering and Information Technology (LiTE) is one out of six conferences held by Lekantara in 2021. Lekantara Annual Conference on Engineering and Information Technology (LiTE) was chosen to be implemented virtually due to the Covid-19 pandemic that is still spreading. The event is virtually implemented with a model that all invited speakers are given time to present their material for 30 minutes every invited speaker and after that a question and answer is carried out with the participants with a direct questioning system, through chat forums and Q&A forums provided by the zoom application. Overall, the conference took 5 hours the number of participants who joined the zoom room was recorded at participants. Participants came from few countries, namely Indonesia, Malaysia, Vietnam, Philippine, United States of America, UAE, and United Kingdom. Lekantara Annual Conference on Engineering and Information Technology (LiTE) is implemented with the support of a stable internet network system and a zoom application. In the implementation there were several technical obstacles encountered by the participants, namely the difficulty of joining the zoom application due to the unstable internet signal. The holding of a virtual conference felt less meaningful, due to the lack of interaction between speakers and participants Lekantara Annual Conference on Engineering and Information Technology (LiTE) committee received 132 manuscripts and a total of 132 papers were presented and discussed. The papers were authored by researchers from Indonesia, Malaysia, Vietnam, Philippine, United States of America, UAE, and United Kingdom All papers have been scrutinized by a panel of reviewers who provide critical comments and corrections, and thereafter contributed to the improvement of the quality of the papers and scope. 91 papers were selected and eligible to be published in the proceeding. We sincerely express our gratitude to the international/national advisory committee, presenters, organizing committee members, session chairs, all members of organization, participants, contributors and all the members of Lekantara Annual Conference on Engineering and Information Technology (LiTE).
