The research titled "Code-Switching and Code-Mixing in Captions and
Comment Sections of Jerome Polin's Instagram Account: A Sociolinguistic
Study" aims to explore the types and factors causing code-switching and codemixing
in the captions and comment sections of Jerome Polin's Instagram account.
This study seeks to provide insights into the types and factors causing codeswitching
and code-mixing in the captions and comments of Jerome Polin's
Instagram account. The data for this research consist of captions and comments on
Jerome Polin's Instagram account containing instances of code-switching and
code-mixing. The data source for this study is the captions and comments on
Jerome Polin's Instagram account. Data collection involves a reading method,
where captions and comments on Jerome Polin's Instagram account are read and
code-switching and code-mixing instances are identified. The data analysis
follows a qualitative descriptive method, and the presentation of the findings is
done informally by describing the obtained results. Based on the analysis, it can
be concluded that there are three types of code-mixing, namely (1) insertion codemixing,
(2) alternation code-mixing, and (3) congruent lexicalization codemixing.
Additionally, there are two types of code-switching, namely (1) internal
code-switching and (2) external code-switching. The factors causing codeswitching
include five factors: (1) speaker or addresser, (2) interlocutor, (3)
presence of a third party, (4) change from formal to informal situation, and (5)
change of topic. On the other hand, there are eleven factors causing code-mixing:
(1) limitation in code usage, (2) use of more popular terms, (3) speaker and
speaker's identity, (4) interlocutor, (5) mode of discourse, (6) topic, (7) function
and purpose, (8) variety and level of language use, (9) presence of a third party,
(10) main topic of conversation, and (11) invoking a sense of humor.
