I have noticed they generally only play the PPV's live but generally do have replays of the free events.
I know they are all free on Fox Sports but there are events that are pay per view in other counties, for example UFC 198 coming up.
You can search online, type "fox sports Indonesia guide" and you should get something.
Generally if they are in the USA, they are Saturday night USA time and Sunday morning here, with the main card starting around 10am or 11am and finishing 2pm
