Abstract

Language has relations to cultural points of view as it has its own uniqueness and also as an indication of cultural values. English and Bahasa Indonesia are different languages with different cultures too. In learning English, Indonesian students, tend to transfer or to use their knowledge of Bahasa Indonesia into English because Bahasa Indonesia has become the lingua franca for Indonesian and it has become their habit. Such condition is called Language interference. Language interference may occur in written and spoken language. This study is intended to identify the Interference of Bahasa Indonesia in students’ english oral production. There are two objectives to be achieved: (1) To find out the types of the interference of Bahasa Indonesia in English oral production of the first grade student of SMA N 1 Purworejo in the academic year 2011/2012, and (2) To find out the types of the interference of Bahasa Indonesia in English oral production of the first grade student of SMA N 1 Purworejo in the academic year 2011/2012. In achieving those two objectives, the writer conducts the descriptive qualitative study, since the data which are performed are in the form of words, phrases, and sentences. In order to analyze the Interference, she uses Contrastive analysis. Contrastive analysis is the aspect of linguistics to identify the structural differences between two languages. It is conducted by contrasting the distinctive features owned by both languages. She also uses several techniques to collect the data, including Recording Technique and giving the questionnaire. By conducting this research, the researcher finds that all five types of language interference still can be found or exists in students’ English oral production. It is 8.13% for cultural interference, 2.44% for semantic interference, 1.63% for lexical interference, 54.47% for phonological interference, and 33.33% grammatical interference. From the questionnaire given to the students, the researcher find that the students are actually conscious of the interference of Bahasa Indonesia in their English oral production and they have done some effort to minimize it (p. 50), but in fact, it is still quite difficult for them to eliminate the interference of Bahasa Indonesia.
