Indeed I really know about this, because I am included the citizens in this country. But I don't think this can reduce bitcoiners in Indonesian, even still many miners from Indonesian are still doing mining and not only that.. many investors are still investing in bitcoin. Indeed bitcoin is banned to be used as a method of payment, but doesn't banned to buy or sell it to local currency, of course I think this is not so very influential on bitcoin price.
It is interesting that they would only ban it as a means of payment, it seems as if they are okay with bitcoin as long as it does not undermine their own currency.
