That’s a Thai name, not an Indonesian name. It’s like saying Jose-Maria Rodriguez a typical British name.
See post 192 - he’s a lawyer from Thailand, owns a restaurant
It does appear to be a Thai name. But having traveled in Thailand & Indonesia extensively, it may, may be Indonesian. But I’m betting Thai.
PS: “Jose-Maria Rodriguez” would not be British, of course. But that name could be Mexican, Puerto Rican, Colombian, or Venezuelan - and all of those regions are so different in culture from each other.
