The use of Standard Indonesian in academic presentations is an important competency for students, including students of the English Language and Literature Study Program whose academic activities often use foreign languages. The ability to speak Standard Indonesian accurately reflects academic proficiency and a positive attitude towards the national language in formal situations. This study aims to analyze the level of Standard Indonesian use in students' academic presentations and identify non-standard language forms in spoken discourse. The method used is descriptive qualitative with classroom presentation observation techniques, audio recording, and transcription of student speech. Data were analyzed based on Standard Indonesian rules in phonological, morphological, syntactic, and lexical aspects. The results of the study indicate that the use of Standard Indonesian is still relatively low. Students often mix Indonesian and English, use non-standard vocabulary, construct ineffective sentences, and use pronunciation that does not conform to norms. Contributing factors include language habits, the dominance of English, minimal formal language practice, and low awareness of the importance of Standard Indonesian in formal academic contexts.
