Demonstrate - Solo, Middle Java, Indonesia

One of demonstrate in Solo, Middle Java, Indonesia. They ask the Train Department to canceled project of Holcim Cement factory in near their house. But their action didn't last too long, because when I go there in the next week, their protest posters has been dissapeared. And guess what...the Indonesia Train Department still continue their project to make a warehouse for Holcim Cement Factory in there...And that factory till now is still running their business so well...
So what the use of their protest actually...
