Variations In "Code-Mixing" Patterns Within Informal Language Styles Among Gen Z In South Jakarta

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,digitalmedia 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.
