This study examines the use of language registers within the home-based kretek cigarette industry in Sampang Village, Cilacap Regency. Employing a qualitative descriptive approach with ethnographic communication methods, the research aims to describe the forms, meanings, and sociocultural functions of specific terms used by workers during the cigarette production process. Data were collected through direct observation, in-depth interviews, and documentation of linguistic artifacts. The findings reveal a unique vocabulary that reflects social identity, work communication efficiency, and the preservation of local culture. Terms such as klobot, mbako srinthil, tingwek, and ngeses symbolize the social and cultural structure of the worker community. These registers carry not only literal meanings but also symbolic and contextual significance, functioning expressively, evaluatively, and as a means of cultural preservation. The study is relevant for the development of contextual language teaching materials and supports culturally diverse learner profiles.

Learning Indonesian for Foreign Speakers (BIPA) is an important means to introduce Indonesian language and culture globally. Rapid digital transformation has brought innovation in BIPA teaching methods, especially through the use of digital media. This article discusses the use of digital media in BIPA learning and the challenges faced. The research method uses literature analysis of ten relevant scientific articles, focusing on digital media innovations such as the e-Tandem model, virtual learning spaces (Cave, Campfire, Watering Hole), and social media applications and special applications. The results of the study show that digital media supports interactive and collaborative learning, expands the reach of teaching, and overcomes geographical barriers. However, there are obstacles such as access to technology and digital skills of teachers. For sustainable effectiveness, the development of digital competency training for teachers is essential. Digital media in BIPA has the potential to promote Indonesian in the international arena and strengthen Indonesian cultural diplomacy.
