<![CDATA[This study aims to analyze Indonesian language errors in academic writing among students of the Primary School Teacher Education (PGSD) Program at Universitas Negeri Medan. The research focuses on identifying the types of language errors, exploring their causes, and proposing solutions to improve the quality of students’ academic writing. This study employed a descriptive qualitative method, with data collected from ten student academic papers selected through purposive sampling. The data were analyzed based on the guidelines of the General Guidelines for Indonesian Spelling (PUEBI), the Great Dictionary of the Indonesian Language (KBBI), and relevant linguistic theories.The findings reveal that the most frequent language errors include incorrect word usage and non-standard vocabulary, improper use of capital letters, inaccurate punctuation, and the mixing of Indonesian with foreign or regional languages without proper adaptation. The main factors contributing to these errors are students’ limited understanding of spelling rules, the influence of everyday language use, and insufficient practice in academic writing. These results indicate that students’ mastery of Indonesian language conventions needs to be improved through more intensive instruction, academic writing guidance, and continuous evaluation. By strengthening their language skills, students are expected to produce academic works that are of higher quality, more communicative, and aligned with academic standards.]]>
