In Jakarta we extend 5 year in Polda Metro Jaya, It was my first time and it was pretty easy... My mistake was going to park first before going to check physical car check, so next time don't park just go straight to physical car check it cost only 10k and give some for the effort now then you park the car. Just follow the direction next after next, first was give it to the counter near the physical car check wait your name then go inside the building then go to the counter 5 yearly counter wait and they call your name , pay, get the number plate and you're done... So easy, it took about 2-3 hour, thought it would be taking on the next.

Something caught my eyes, there was drive through for extending yearly car registration, need to try this...
