INTRODUCTION
In daily communication, we often see people speaking in more than one language, this is occurred due to people can speak in other languages besides their mother tongue. This phenomenon has seen everywhere such in daily life, television program as well as in social media. Sometimes, people mix two languages in single utterance while they are talking. The ability of mastering more than a language known as bilingualism or multilingualism in sociolinguistics. As stated by Mackey (1970:555) in Hoffman (1996:16) bilingualism is the alternate use of two or more language by the same individual.
Wardaugh (2010) stated that "bilingual is a speaker who can speak in two codes, and for some reason change their code when they are speaking" (p.11). When people shift their language, dialect, or variety while they are speaking, they are in a state of doing code-switching or code-mixing, they can shift it within their sentence, or in the next sentence. For example: A: Well I'm glad I met you. OK? M: ándale pues (Spanish) [ OK SWELL], and do come again. Mm? (Switch between Spanish and English) (Holmes,35) Mahootian (2006) has reported that there are two types of code switching that can be identified, they are intrasentential (the switching occurred within a clause, involving a phrase and morpheme) and intersentential (the switching occurred between sentences or clause boundaries) meanwhile some researchers have used term of code mixing to refer specifically to intrasentential switching and this research will conduct refer to code mixing. In most current literature, however, the term 'code mixing' is used interchangeably with 'code switching,' with both terms referring to both types of language mixing.
As mentioned above, the phenomenon of code switching or code mixing is spreading in daily life, not exception in social media, since there are so many social media available such as twitter, facebook, Instagram, Youtube and many else, I use videos as my source of data, thus Youtube is a suitable platform to obtain my source of data since Youtube is the biggest platform for online videos with 1.8 billion monthly users nowadays. In Youtube, we can find so many videos by only typing some keywords.
Nowadays, Youtuber has been kind of job, they are uploading their videos on their channels and get paid of it, no wonder that Youtuber has been widely spread in all over the world, they are coming from any region, state, and country. The chosen channels to be analyzed in this research are Youtube channels organized by Indonesian who currently living abroad which is in Germany, they often share their living experiences abroad through their videos. The research questions are (1) What are the types of Code-Mixing used by Gita Savitri Devi and Sarrah Nurul in their Youtube channel videos? (2) What are the reasons for the use Code-Mixing used by Gita Savitri Devi and Sarrah Nurul in their Youtube channel videos? This research is aimed to find out the type of their code mixing and the reasons why they mix their Indonesian utterance with English while they are talking in their videos.

This study investigates code mixing used by Kimmy Jayanti. The second research is entitled "Code Switch Used By Sacha Stevenson in Tonight Show and Sarah Sechan on NET TV". It aims to find the types and factors of code switching. The third research is entitled Motivation Behind Code Switching Among Kuwaiti Bilingual Schools Students by Fatemah. This research is aimed to find out the reason or motivation Kuwaiti bilingual school students do code-switching to English even though they are not an immigrant community nor were colonized by English speaking country. The fourth research is entitled "Language and Identity: Bilingual Code Switching in Spanish-English Interviewers" by Maria Cecilia Velasquez. The purpose of this study is to understand why and how language alternation occurs in bilingual interviewers and its potential connection to identity. The differences in all of the previous studies are located in the source of data, the informant, the number of analyzed videos and the theory in analyzing the data.
