Hi @FredyDwi,
I noticed here that you posted that you are running OJS 2 (which we no longer support): Problem in Change Homepage Title Image
Is this a different instance of OJS that you are running? If so, it would be really helpful to know the version, number. You can see here for checking the version number: How do I determine my PKP software's version?
Knowing the version number is important to offering potential solutions for your problem.
And, just to be sure that I’m understanding your issue correctly: the author is looking to receive a notification for the articles that they have submitted?
