Television as one of the influential mass media can give a big effect to its viewer. Television offers some information and entertainments. Furthermore, many Television channels are raced to get the viewers’ attention in order to get the best rating, they provide many programmes that have a unique characteristic. For young viewers, the most interesting TV programme is a Music programme. Net TV as one of the channel, has a music programme, namely Breakout that the young viewers said that it is the best music programme in Indonesia because it generally appear with some abroad musicians as the guests. Typically the hosts used in Breakout is the one who can sing, play some music instruments and the one who can speak English well. Most of the hosts who present in Breakout are Bilingual. They often use Indonesian language and English while presenting the programme. They often do code switch and it was almost during the programme began until it ended up. In this study, the researcher focus on two names of the hosts, Boy William and Sheryl Sherafina because those two hosts are the main hosts in that programme. This Study is focus on the language style and the code switching used by the hosts as well as the linguistic impact toward the students of Junior High School as the viewers. In general, this study will elaborate what kinds of code switching used by the hosts of Breakout, what language style they use and what are the linguistic effect from the hosts’ code switching and language style toward the students of eight grade in Miksyaful Ulum as their viewers.In the previous study written by Laurentius Pradipta Yunanda (2016) under the title “Code Switching in Indonesian artist Twitter Tweet” showed that artist’s code switch was a trend. This research exposed that the code switching in the twitter tweets of Indonesian artists were tag-switching, inter-sentential switching, and intra-sentential switching. In addition, the Indonesian artists used the code switching combination in their tweets. Another study under the title “The Different Language Style and Language Function between Students and Teachers in Updating their Status in Facebook Webpage” written by Nurul Adhalia (2011) showed that the student’s language style was casual meanwhile the teacher was used formal. And both of them used expressive function language in their sentence. From those two previous research it seems that code switching was a trend used by our public figure in Indonesia, but there is no later project investigating the impact of the code switching and the language style used by them toward the viewer’s especially the viewers on school age. This study will elaborate what kinds of code switching and language style used by the hosts of “Breakout” as well as the linguistic impact given by them toward the students of MTs. Milsyaful Ulum at eight grade as the viewers.2. Theoretical Framework 2.2 Bilingualism In the beginning of 19th to the middle of the 20th century , a great number of linguists seen bilingualism/ multilingualism as the usage of two or more different languages, and it has a harmful effect on human being’s logical and spiritual growth” (Wei, 2000). Then some influential work from Weinreich (1953), Mackey (1968), Ferguson (1964), Fishman (1968), Gumperz (1964), et al., characters a radical change and creates the stage view positively toward bilingulism (Mackey, 2000), (Ferguson, 1977), (Fishman, 2000). Fishman et. al (1971) in Setiawan (2013) stated that bilingualism may not have the same mastery or equality from the frequency in both language practise. He said that the fluency in bilingualism can be based on what language is mostly used in practice. Furthermore, the expert said that when the language is not often to be used, language proficiency will be decline (Setiawan, 2013). 2.2 Code SwitchingWardaugh (2006) tells that people use a code when communicate with other people. In addition, Van Herk (2012) shows that speaker use code switching with their own purpose. Furthermore, code switching is seen as the connection within the same speech interchange of texts of speech and belonging to different grammatical system or subsystem (Gumperz). Moreover code switching is defined as the action of changing or shifting from one language, dialect or varieties to another depending on the condition (Asher, 1994)However, in this paper, the types of code switching based on Poplack will be the base of the analysis. 2.2.1 Types of Code SwitchingIn this study, the researcher used types of code switching based on Poplack (1980). Based on Poplack theory there are three kinds of code switching and it was cited on Romaine (1995), those examples are:a. Tag switching is an activity when the speakers attaches or adds some filler in the sentence. The speakers adds a word or words in a sentence without changing any grammar rule.b. Inter-sentential code switching: inter-sentential code switching is an utterance where the speakers switches his/her codes in a full sentence or between minimally two sentences.c. Intra-sentential code switching: it happens where the speakers switch the code within a sentence. The switch is in the form of word, sentence, and phrase. 2.3 Language Style:There are some kinds of language style as written by Martin (2000). He classified both spoken and written style into five stages (Martin, 2000), such as:a. FrozenThis is a formal style usually used in formal occasion. The form is fixed and based on standardized language.b. FormalThis is a style stated in formal occasion too or in a meeting. Standard speech with a low tempo speech, perfect technical vocabulary, complex and divergence grammatical structure.
