Abstract

This study aims to identify the causes of errors made by students in solving limit function problems. Limit concepts often present challenges to students due to their complexity, which can lead to confusion. In this research, four students from the Mathematics Education Program at Universitas Negeri Medan served as the subjects, participating in interviews and written tests. They were given limit problems to assess their difficulties in understanding the material. The findings revealed a variety of errors made by the students. Approximately 75% of these errors were due to their inability to organize proper solution steps and incorrect application of formulas. Additionally, 50% of the errors resulted from a lack of understanding of the definition of limits, while 25% were attributed to calculation mistakes or oversights. These results indicate that many students still struggle with the fundamental concepts of limits and the correct methods for solving these problems. To improve student comprehension in this area, it is recommended to implement more interactive and focused teaching methods, enabling them to better grasp the concepts of limits and the appropriate techniques for problem-solving.

Abstract

This study aims to evaluate the level of student satisfaction with the facilities and infrastructure available at the Medan State University (Unimed) Dormitory. Adequate facilities have an important role in creating a comfortable learning environment and supporting academic productivity. This research uses a descriptive quantitative approach through a survey method, by distributing questionnaires to 23 respondents who are dormitory residents. The results of the analysis show that the level of student satisfaction with dormitory facilities varies. The security and comfort aspects of the study rooms received positive responses, while the availability of water, bathroom cleanliness, and the quality of the internet network are still factors that cause dissatisfaction. Although most respondents expressed satisfaction with the general cleanliness of the dormitories, improvements are still needed in terms of management services, facility maintenance, and the development of supporting infrastructure. The conclusion of this study shows that although some aspects of the facilities have met the standards, improvements are still needed in the management of facilities and infrastructure to increase student satisfaction. Improving the quality of facilities is expected to create a dormitory atmosphere that is safer, more comfortable, and conducive to the continuity of the student academic process.
