The Role of Code-Mixing in Gen Z Intercultural Communication, Social Harmony, Arab Community, Betawi Community, Multicultural Society

Abstract

This study examines the phenomenon of "code mixing," popularly known as the "Anak Jaksel" (South Jakarta youth) language style, among Generation Z in South Jakarta as of 2025. In the era of globalization, language has transformed from a mere pragmatic communication tool into a vital instrument for forming cultural and social identities. This research aims to comprehensively analyze the variations of code-mixing patterns, the underlying sociocultural factors, and their implications for social identity construction within a global urban society. Using a qualitative approach and in-depth interviews, the study found that the most dominant form of code mixing is intrasentential, specifically the insertion of English lexical words into Indonesian sentence structures. Common terms such as "anxious," "literally," or "make sense" are often used spontaneously, influenced by social circles, digital media exposure, and the internet. The findings indicate that this practice serves as a linguistic strategy to create more relaxed, comfortable, and expressive communication. Furthermore, based on Social Identity Theory, code mixing functions as a group identity marker that fosters a sense of belonging and confidence among Gen Z. However, the study also reveals a process of identity negotiation; informants consciously adjust their language by reducing code mixing and using formal Indonesian when interacting with lecturers or older individuals to maintain professionalism and politeness.
