Jawaban:Penjelasan:Saperangan ngoko alus" translates to "a part of ngoko alus" in Javanese. Ngoko alus is a form of Javanese speech that uses some formal (krama) vocabulary mixed with informal (ngoko) vocabulary to show respect, often used when speaking to someone who is older or of higher social status, but with whom you have a close relationship. Here's a more detailed explanation:Ngoko:This is the informal, everyday Javanese language used with close friends and family. Krama:This is the formal, polite Javanese language used to show respect to elders or those of higher social status. Ngoko Alus:This is a combination of the two. It uses some krama vocabulary (especially verbs) within an overall ngoko sentence structure, creating a tone of respectful informality. Example:Instead of saying "Kowe arep lunga menyang ngendi?" (You are going where? - using the ngoko word "kowe"), you might say "Sampeyan arep tindak ngendi?" (You are going where? - using the krama word "sampeyan" and "tindak") in ngoko alus. Essentially, ngoko alus is a way to be respectful without being overly formal, striking a balance between familiarity and deference.
