I agree with Terecia's answer, I however still want to add its usage in different context. 1) To soften request - Aku juga mau ikut ke pesta ulang tahunmu (dong) / I also want to join your birthday bash (please). - Perempuan dulu (dong) / Ladies first (please) - Aku tidak mau jalan, pesan taksi aja (dong) / I don't want to walk, (why don't we just) order a taxi 2) To highlight impatience - Kalau kamu tidak menyapa dia sekarang, (kapan lagi dong) kamu bertemu dia lagi? / If you don't greet him now, when else will you see him again (c'mon)!? - Aku tidak bisa disalahkan (dong!) / I can't be blamed, (c'mon!) - Kembalikan bukuku sekarang (dong!) / Return my book now (please!) - Ambil keputusan sekarang (dong!) / Take the decision right now (please!) I hope that helps.

Iya dong means yes, it's true. It's a particle to soften a phrase or a sentence. It can be used at the end of a sentence or sometimes in the middle. It's used in an informal speech. I'm quite sure whether it has a similarity kind of word or expression in English. Here are some examples of the usage "dong": - Kamu jangan begitu dong, aku hanya bercanda (please, don't be like that, I was just joking) compares with: - Kamu jangan begitu, aku hanya bercanda - Kalau bukan kamu, siapa dong yang menyembunyikan dompetku? (if it wasn't you, who else that hid my wallet?) compares with: - Kalau bukan kamu, siapa yang menyembunyikan dompetku? Unfortunately, I can't translate the difference between the sentences which use "dong" and the one without "dong". All I can say is that the word "dong" implies a softer tone. Apakah penjelasan di atas cukup membantu? Regards, Tere

The meaning of "dong" (part I) Selamat malam, Pak I make a concise note about the word "dong". Hopefully, they help. The word “dong” usually used in informal speech.

"Dong" is an ending that can't be translated literally to English and many other languages. If you have experience with Singlish or Chinese, you may notice that there are endings "la", "luo", "ma", etc that don't mean anything particular. It is just a style of talking.
