Ottoman Indonesia is most likely in two options:
1. Various Sultanates who accept Ottoman protection. From Aceh to the Moluccas. No direct rule but Ottoman Naval Units are nead to protect it. As @kasumigenx says, significant Ottoman presence in Indonesia before the 1570s might prevent Spanish Rule over the Philippines.
2. Aceh places itself under Ottoman Rule. Not entirely Indonesia but partly.
Spain is going to get her hands on a resupply point for the Pacific galleon trade, one way or another. There's just too much profit to be made from shipping New World bullion from Mexico and Peru to China. Though, given a Portugal beaten out of commerce past Cape Horn is much weaker, might we see Spain renting out Macua as a trade space instead? They could count on the Chinese navy for coastal security. Or maybe they'd bump into Hawaii?
