How to say "thank you" in Bahasa

Indonesia is a warm-hearted country. We realize: no one is an island. This is the beginning of our social treasure I guess. There are so many ways to show how much you blessed, how much you thankful to someone or something. Here, we say "thank you," by "terima kasih". When you get some help, just say "terima kasih" and don't forget to smile. :) Even if you forget to say these two words, the smile on your face is more than enough to express it.
