This study examines the form of Sasak language interference in Arabic language practice by students of Madinatul Ulum NW Mumbang Islamic Boarding School. Interference occurs in various aspects of language, including phonology and syntax as well as reduplication. This phenomenon is caused by the influence of the mother tongue (Sasak language) and the lack of mastery of Arabic vocabulary of students, as well as minimal understanding of Arabic language structure. This study uses a qualitative descriptive phenomenological approach, the data were obtained through observation, interviews and documentation. The results of the study showed that phonological, syntactic and reduplication interference dominated students' errors in speaking Arabic. To minimize the negative impact of this interference, the Islamic boarding school implemented several intensive programs, such as muhadasah, memorizing the muhawaroh book, drilling uslub and watching Arabic films as well as learning Nahwu science. This finding confirms that although mother tongue interference (Sasak language) is a real challenge. However, the application of the right learning method and a supportive learning environment can significantly improve the Arabic language competence of students.
