In Jakarta Yuda calls his mother, who live on other island, from a public phone. Jakarta public phone doesn't serve inter-city calls and the coins he uses are not enough for long conversation (in the international version, the conversation is much shorter than in the Indonesian version).
In the fight towards the end, the crowbar used by Luc appears to bend when struck against the Yuda's rod, indicating it's a rubber prop.
The blood from Ratger's face becomes pink when it touches his shirt.
When Yuda is putting coins into the telephone for the second time, you can here the coins get rejected yet the phone goes through anyway.
Yuda left his small bag on construction site after on previous day his wallet was stolen once and he know none of the construction worker and he slept for the whole night on there after crossing the fence illegally. (This scene doesn't appear on International version.)
