videos from five different YouTube channels. Based on the findings from this study,
the types of code-mixing found in this study are intra-sentential code-mixing and
intra-lexical code-lexical, while for code-switching, the types were found are tag
switching, intra-sentential code-switching, and inter-sentential code-switching. The
use of code-mixing and code-switching of lecturers are different. Some lecturers use
more code-mixing, while the other lecturers use more code-switching, and there are
also lecturers who use both equally. Possible reasons for code-mixing and code�switching found in this study are talking about a particular topic, quoting someone

and expressing group identity and solidarity. It can be concluded that, code-mixing
and code-switching are language phenomena that are useful to make communication
