Meeting and Greeting
Given that they are intended to express respect, greetings can be fairly formal. The most typical form of welcome that includes the word "Selamat" is a handshake. After shaking your hand, a lot of Indonesians might do a small bow or put their hands over their hearts. Always introduce the oldest or most senior person first when meeting multiple people.
In Indonesia, titles are significant because they denote status. Make careful to use any titles you are aware of along with the name. Although having a first name plus a surname is more and more typical, particularly among middle class Indonesians, some people still just have one name.
