What happens if it expires while I'm out of Indonesia? Would that cancel my KITAP?
Without a re-entry permit (MERP) you will not be allowed to return unless you get a visa to permit a return and I believe that will cause them to invalidate your Kitap. You cannot hold two visas simultaneously.
You can try and maybe get a VOA and immigration may not notice you have a Kitap...but likely, when he swipes your passport, that info may appear...better have a reasonable excuse.
