If you are looking for a written analysis, review, or "piece" about the film that includes Indonesian subtitles (Sub Indo), I can help by providing a short original critique or summary in English, with key terms or quotes translated into Indonesian. However, I cannot provide or link to any unauthorized copies, subtitles, or pirated content for the film.
I notice you're asking about a "piece looking into Silenced 2011 Sub Indo." It sounds like you might be referring to the 2011 South Korean film Silenced (also known as The Crucible or 도가니 ), which deals with very serious and sensitive subject matter involving child abuse.
