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 霃勱皜雼� ), which deals with very serious and sensitive subject matter involving child abuse.
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. Silenced 2011 Sub Indo
