Abstract Name : Deafi Denilda Student No. : 1306102020059 Study Program : English Education Department Title : An Analysis on Code Switching of Indonesian and English in Travel YouTubers Keywords: Code Switching, Indonesian YouTubers, YouTube This study aimed at investigating the types of codeswitching and the functions of code switching used by Indonesian YouTubers in their YouTube travel- content videos. This descriptive qualitative study was conducted by collecting the data from Indonesian YouTubers’ travel-content videos by watching and transcribing them. The results of the study showed that there were four types of code switching used by Indonesian YouTubers which are inter-sentensial switching (10.92%), intra- sentensial switching(58.76%), tag switching (28.81%), and establishing continuity with the previous speaker (1.51%). Intra-sententialswitching was the type of code switching that was most widely used by the participants because it was easier to be used in daily conversation. Meanwhile, there are six functions of code switching, and the researcher found quotation (0%), addressee specification (7.39%), interjection (75.37%), reiteration (6.40%), message qualification (7.39%), and personalization vs. objectification (3.45%). Interjection was the function of code switching that was most widely used by the participants since it helped the participants show their expression clearly using interjections in English tag. In conclusion, the researcher considered that the intra-sentential switching was easier to be used by Indonesian YouTubers since it occurred only in a brief phrase within a sentence for their daily conversation, while interjection function helped the participants to show their expression clearly to attract the attention of the listeners by using interjection in English tag. The researcher hoped that this research can be an idea for further researchers who want to undertake a study related to the use of code switching in such media platforms as instagram, twitter, etc.
