The results showed that the highest category for students was learnability and efficiency, with a score of 5, and the lowest in the error category was 4, with an average score in each category of 5. While for students with the highest category learnability with a score of 4 and the lowest in the error category with a score of 3 with an average score in each category is 4, with an average score in each category of 4. Indicates that there were differences in perceptions between students and librarians. Students gave an average score of 4 on the five variables, while librarians gave an average score of 5. Librarians' perceptions showed excellent mastery of the OPAC interface. Meanwhile, students' perceptions showed good mastery of the OPAC interface.
