My husband went to Indonesia where he is from and is now planning on getting married to someone there, is there anything I can do?

You can file a divorce here or in Indonesia. Until you are divorced, his marriage in Indonesia will not be recognized here as bigamy is not recognized. I don't know if it is in Indonesia. If not, the marriage won't be valid there either.

Yes, file for divorce the marriage is obviously over. You can't stop him if he were here, he would be committing bigamy and the new marriage would be invalid but he's not here.
