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.
