Open Journal System (OJS)
Hi. Great work on getting Moodle app @atrilahiji
I would also suggest Open Journal Systems if you mind to take a look https://pkp.sfu.ca/ojs/
Here is example : https://ojs.akbidpelamonia.ac.id/index.php/journal
This is much needed in higher education institution i know for lecturer for peer review their journal/publication. University here in Indonesia always use it together with Moodle for knowledge management apps.
