From some local community leaders, it has been told that the title Batu comes from the name of a cleric follower of Prince Diponegoro named Abu Ghonaim or referred to as the Kyai Gubug Angin which later the local community was familiar with calling it "Mbah Wastu". From Javanese cultural habits that often shorten and shorten the designation of someone's name which is considered too long, also to make it shorter and faster when calling someone, finally Mbah Wastu is called "Mbah Tu" to be "Mbatu" or "Batu" as a term used for a mild climate city in East Java.
