The deadline for submitting an abstract is 9 July 2021. You will be asked to fill a personal information, title and short abstract, and your mobile phone number. You will be asked to upload the abstract pdf file. Please use Word Template and LaTeX template for your abstract.

Please use this Word Template and LaTeX template and submit the source file via the EasyChair submission page for the conference (you need to subscribe to EasyChair before submitting). The length of the abstract should be between 150 and 250 words. All abstracts must be written in English. Each registered conference participant may present more than one contributed talks. All accepted abstracts will be announced on 23 July 2021. The time allocated for each presentation is about 15 minutes with an additional 5 minutes for discussion.  

If you find any difficulties in using the EasyChair system, please send the abstract to the committee ( with cc to;; ).

Paper Submission

The selected refereed papers will be publish in the JOURNAL OF PHYSICS:CONFERENCE SERIES  indexed by SCOPUS of h-Index 59, IF-like 0.488, and Coverage: 2005-ongoing. Please visit SCIMAGOJR and check the details. The rest of the refereed papers will be published in the Indonesian Journal of Combinatorics  indexed by DOAJ and Crossref with DOI Number, Pancaran Pendidikan indexed by  Google Scholar and  Crossref with DOI NumberVisit and type those name of journals for checking the indexation.

The maximum number of paper pages is 10 pages including references, figures, title, authors, affiliations, e-mail addresses, and abstract. All submissions have to be made via the EasyChair submission page for the conference.
