Abstract

This study aims to analyze the effectiveness of ChatGPT as a tool to help students complete academic assignments. Using a quantitative descriptive method, this study involved 150 6th semester students of the Mathematics Education Study Program selected through a simple random sampling technique. Data were collected through an online questionnaire that measured the intensity of ChatGPT use, ease of understanding the material, and its impact on learning outcomes. The results showed that the majority of students felt helped by the use of ChatGPT, especially in compiling essay assignments, understanding complex academic concepts, and increasing self-confidence in solving math problems. However, it was found that excessive use has the potential to reduce learning motivation if students rely too much on instant answers. Therefore, wise use of ChatGPT and integration with conventional learning methods is highly recommended so that students continue to develop critical thinking skills and independence in learning.

Abstract

Learning concentration plays a crucial role in students' academic success and can be influenced by various factors, including sleep quality. This study examines the relationship between sleep quality and mathematics learning concentration among seventh-grade students (VII-3) at SMPN 4 Medan. A descriptive correlational method with a quantitative approach was used. Data were collected using a sleep quality questionnaire based on the Pittsburgh Sleep Quality Index (PSQI) and a learning concentration questionnaire. Statistical analysis included the Chi-Square test, Pearson and Spearman correlation, and Odds Ratio estimation. Results showed that 54.5% of students had poor sleep quality, while 45.5% had good sleep quality. Regarding concentration, 54.5% of students exhibited good concentration, while 45.5% struggled to focus. Statistical tests confirmed a significant relationship between sleep quality and learning concentration (p = 0.007), with a moderate positive correlation (r = 0.467). The Odds Ratio indicated that students with good sleep quality were eight times more likely to have high concentration. These findings emphasize the importance of proper sleep habits in improving students' focus and academic performance.

Abstract

This study analyzes the impact of KKNI assignments on sleep quality and productivity among 2023 Construction Management students at Universitas Negeri Medan. Using a quantitative approach with a correlational survey design, this research measures the relationship between KKNI assignment workload, sleep disturbances, and their effects on students' academic productivity. The results of multiple linear regression analysis indicate that late-night study habits, reduced sleep duration, and fatigue during lectures due to KKNI assignments significantly affect student productivity. Students who frequently stay up late experience a decline in productivity due to disruptions in physical and mental recovery. Although some students can adapt to academic pressure, the negative effects of sleep deprivation outweigh the productivity gains from academic demands. This study provides valuable insights for educational institutions in formulating more balanced academic policies to support student well-being. ABSTRAKPenelitian ini menganalisis pengaruh tugas KKNI terhadap kualitas tidur dan produktivitas mahasiswa Manajemen Konstruksi Universitas Negeri Medan angkatan 2023. Dengan pendekatan kuantitatif menggunakan desain survei korelasional, penelitian ini mengukur hubungan antara beban tugas KKNI dengan gangguan tidur dan dampaknya terhadap produktivitas akademik mahasiswa. Hasil analisis regresi linier berganda menunjukkan bahwa kebiasaan tidur larut malam, berkurangnya waktu tidur, serta rasa lelah saat kuliah akibat tugas KKNI memiliki dampak signifikan terhadap produktivitas mahasiswa. Mahasiswa yang sering begadang mengalami penurunan produktivitas akibat terganggunya proses pemulihan fisik dan mental. Meskipun sebagian mahasiswa dapat beradaptasi dengan tekanan akademik, efek negatif dari kurang tidur lebih dominan dibandingkan peningkatan produktivitas akibat tekanan akademik. Penelitian ini memberikan wawasan penting bagi institusi pendidikan dalam menyusun kebijakan akademik yang lebih seimbang guna menjaga kesejahteraan mahasiswa.
