Hi syazwani, thanks for reporting this in.
There is an issue in how one of the pages is set up that's preventing you from completing it, and continuing with the course. We will let the course staff know and ask them to change it. We'll let you know as soon as it is resolved.
Hi syazwani ! Good news! The issue has been fixed. You can now go back and complete Nota tambahan. When you do that, the module will be complete, and you will be able to continue to the next module.
Good luck! :)
