<![CDATA[Plagiarism is an academic problem that often occurs in higher education environments, including in the preparation of students' scientific works. This phenomenon is caused not only by students' lack of understanding of scientific writing ethics but also by limited skills in correct citation and paraphrasing. This study aims to analyze the role of libraries in reducing the level of plagiarism in student scientific work at Muhammadiyah University of Purwokerto. The research method used was a qualitative phenomenological approach, using data collection techniques such as interviews, observation, and documentation. The results indicate that libraries play a strategic role in reducing plagiarism through several efforts, including providing adequate reference sources, information literacy training, promoting the use of reference management applications such as Zotero and Mendeley, and utilizing plagiarism detection software such as Turnitin. Furthermore, librarians also act as facilitators of academic education, helping students understand the importance of scientific integrity. However, obstacles remain, including low student awareness and suboptimal utilization of library services. In conclusion, libraries play a significant role in reducing plagiarism, but increased collaboration between libraries, faculty, and institutions is needed to optimize this role. Sustainable efforts in information literacy education are key to building an honest and responsible academic culture. Keywords: library, plagiarism, student scientific work.]]>
