"Permisi, selamat tinggal."
Translation:Excuse me, goodbye.
Both is used to say goodbye but the difference is in the person leaving or staying. Eg. After my friend visits my home and is leaving, i would say to him "Selamat Jalan" (Have a safe trip) and he would say to me "Selamat Tinggal" (Stay Safe). If both are leaving eg. after school, either phrase may be used.
