As a culturally rich region on the island of Java, Yogyakarta has significant linguistic diversity. The Javanese language, as the dominant regional language, is used by most residents in daily life. This language interacts with Bahasa Indonesia as the national language and English, which is often used in the tourism sector and global interactions. However, the presence of these three languages in public announcements remains under-researched.
A research team from the Department of Languages, Arts, and Cultural Management (DBSMB), Vocational College, Universitas Gadjah Mada, conducted a study from May to October 2024 that explored the use of Javanese, Indonesian, and English in public announcements in Yogyakarta, particularly at Tugu Yogyakarta Railway Station and Yogyakarta International Airport. This research aligns with the Sustainable Development Goals (SDGs), particularly in promoting creativity and innovation in cultural expression.
