Using a qualitative descriptive case study, data were gathered through classroom observations, documentation, and semi structured interviews with fourth-semester students of the English Education Department at UIN Sultan Maulana Hasanuddin Banten. The findings revealed 117 utterances containing code-switching and code-mixing. Three types of code-switching were identified: inter-sentential switching 30, intra sentential switching 24, and tag switching 11 utterances. three types of code mixing were found: insertion 48, alternation 4, and congruent lexicalization 0 utterances. Among these, intra-sentential switching and insertion mixing were the most dominant, Inter-sentential switching was dominant because students prepared their presentation scripts beforehand, allowing them to plan language shifts between sentences more naturally. Insertion mixing frequently appeared since English terms were familiar and commonly used in academic settings, making communication more efficient. In terms of communicative functions, six major functions were identified based on Appel and Muysken’s framework: referential 71 utterance, directive 17, expressive 5, phatic 12, metalinguistic 11, and poetic 1 utterance. The referential function was the most frequent, as students often switched or mixed languages to explain academic concepts and theories for better audience understanding, indicating that language was mainly used to convey information more clearly and to manage the flow of presentation. The interview results showed that students used language alternation to improve clarity, manage nervousness, enhance confidence, and engage the audience. They considered these bilingual practices effective for supporting comprehension and interactive learning environment. For the next researchers, it is encouraged to explore code-switching and code-mixing for the improvement of communication in different academic settings.
