2 instruments, norms of interaction and interpretation, and genres form and variety of
language. Those components will influence the product of language. For instance when participants have different level of English, it might cause the mix and switch of
language in order to send messages continuously. In another example is when a speaker and a hearer have a purpose to make jokes by using codes during informal
conversation. People rarely use one language in a community. When people use one code, it
becomes interaction each other so when they speak to each other, then at least they speak more than one language. Whether they use one switch, add taken for other
languages. Terms added are called as code switching. Meanwhile, Lumintantang 2002 points out that code switching occurs in
Indonesia as multilingual society, therefore, Indonesian tend to switch at least from national language to local language. Moreover, Bahasa Indonesia as the national and
state language made the bilingual is existed. This sociolinguistic phenomena cause the use of code – switching because generally, Indonesian speak their local language and
Bahasa Indonesia and the assimilation from English, so that’s they are called multilingual.
1.2 Reasons for Choosing the Topic
Communication in the radio is very effective. The means of communication in the radio gives people with different place, status, culture, nationality, etc a chance to
communicate each other. Because of their interaction, people tend to use switch one code to another code.
3 Any number of codes switching from different languages is used in a radio
program; Uncle JC Happy Hour is one program in Smart FM Jakarta. This program hosted by Fanny Belnis, Manadonese and John Christoper Falch, an American. It was
broadcasted in 6 cities in Indonesia; Jakarta, Manado, Makasar, Balikpapan, Palembang, Semarang and Surabaya till 2004. This is not any longer existed.
During the program, listeners could ring to discuss some issues of program. They often use code – switching during the interactive talk though code mixing also occurs.
Compare with other radio English programs, there is a different environment with operator, two host DJs and guests, with local and expatriate as callers. The announcers
and some callers often switch English into other languages as the result of the change of situation and topic, where sometimes the announcers mean to have jokes or when
callers can not find the proper words or sentence thus there was no limit for mixing and switching other languages. JC has a good trick in order to make them not to be afraid
with mistakes or shy to speak in English on air though they lack of knowledge and skill thus code switching occurs into another language. The image of the call sign “Uncle JC
Happy Hour” also makes sense since Uncle JC most of times make Fanny and some callers laugh about what he says and are happy. We can also find the special effects to
convince listeners’ imagination, funny songs and short parody to make listeners practice English with a lot of fun. Those are points which keep listeners to stay tune.
1.3 Statement of the Problems
This study will answer the following questions: 1 What conversational function of code switching did occur in Uncle JC?
2 What factors accounted for the code switching?
