In practice, a language is a tool for conveying messages from the articulator to the auditor, requiring adjustments in carrying out their duties. Thus, the essence of the language process is how messages can be conveyed effectively and efficiently by using the method that is considered the best. Language is constantly developing and changing. These developments and changes occur due to various factors, such as social, economic, and cultural dynamics. Using two languages side by side can cause language distortion in practice. The problem emphasized is the shift in the Betawi dialect in the family sphere, especially the Betawi descendants who live in Jakarta. This study aims to determine the form of the shift in the Betawi dialect. Data was provided using a questionnaire and random interviews explicitly aimed at several Betawi communities in the family realm. Then the data is described phenomenologically by looking at the basic principles of speech components as a reference for the analysis. From the research that has been done, it was found that the dialect shift that occurred in the Betawi community occurred in the generation of children and parents. This shift in form can be identified in the Betawi vocabulary, which shifts to another vocabulary. Another language which Indonesian dominates has indirectly become the second language of the Betawi people. Meanwhile, the causes of the dialect shift in the Betawi community include the influence of language variations and the lack of loyalty of the local community. This condition must be answered immediately, and a solution sought for the great good.
