INTERFERENSI FONOLOGI PADA PEMBELAJAR BIPA ASAL EROPA DI BALI
This study aimed to determine phonological interference that occurs on BIPA learners from Europe in Bali. Oraland written data are used in this research that were obtained from learners' speeches and writings when learning Indonesian in the class. This research was guided by interference theory according to Weinreich (1953). Oral data were collected using proficient inversion techniques (SLC), skillful in-flight listening techniques (SBLC), recording techniques, and note taking. Writing data were collected by the test method. The data analyzed and presented in formal and informal forms. The results of data analysis showed that phonological interference that occurred in BIPA learners from Europe in Bali, namely in the form of vocal noise interference (occurred in vowels [a], [u], and [ə]), consonant sound interference (occurred in consonants [h] , [r], [g], [ŋ], [t], [g], and [ɲ]), interference in the form of sound addition (occurred in the sounds [ŋ] and [ɲ]), and interference in the form of sound removal ( occurred in consonants [r], vowel series [e] and [a], and consonants [h]). This interference occurred because of differences in vowel and consonant sounds in Indonesian and English. In addition, this interference was also caused by the different pronunciation of a vowel sound or consonant sound in both languages.
