Film Merantau Lk21 【HOT – TRICKS】

I need to check if there's any confusion with another film. There's a 2016 film titled "Merantau: The Journey of Migrants," but I think the main one is from 2009. Also, maybe "LK21" is part of a longer title in Indonesian, but I don't recall it. So, proceed with the 2009 film as the primary subject.
