Students in the Information Systems Program at UIN Sumatera Utara tend to have irregular eating patterns with high consumption of fast food. This habit contributes to various health problems such as digestive disorders and decreased concentration. This study was conducted to investigate the eating patterns of students in the Information Systems Program at UIN Sumatera Utara and their relationship with their health conditions. Through a quantitative survey of 50 respondents, the results showed that most students eat less than three times a day, with the highest frequency being twice a day (48%). Additionally, the majority of students consume fast food 1–2 times a week (60%). Analysis using the Chi-Square test revealed a significant association between the frequency of fast food consumption and students' health conditions (p < 0.05). Many students experienced health issues such as stomach problems and fatigue related to their unhealthy eating patterns. These findings emphasize the need for nutrition education and the implementation of practical healthy eating patterns to support students' health and academic performance.

The implementation of Electronic Medical Records (EMR) has become a pivotal advancement in enhancing hospital service quality. This study aims to analyze the impact of EMR implementation on the quality of healthcare services by comparing the conditions before and after its adoption. Through a comprehensive literature review of peer-reviewed articles published in the last ten years indexed by Scopus, Web of Science, and Sinta 1 and 2, this research identifies key improvements in efficiency, data accuracy, patient safety, and user satisfaction. The findings reveal that EMR significantly reduces medical errors, shortens patient waiting times, and improves interdisciplinary collaboration. However, challenges such as infrastructure readiness and human resource adaptation remain critical barriers. The study concludes that strategic planning and continuous training are essential to maximize the benefits of EMR for sustainable service quality enhancement in hospitals.

This study aims to examine how transformational leadership by school principals plays a role in improving teacher performance at the elementary school level. The research adopts a literature study approach, with data collected through documentation and analyzed using the Systematic Literature Review (SLR) method. The findings indicate that transformational leadership by school principals has a significant impact on enhancing teacher performance. Principals who are able to inspire and motivate teachers through a clear vision, emotional support, and by providing space for innovation can create a conducive work environment for professional teacher development. Furthermore, a leadership style that encourages collaboration and gives recognition for teachers’ achievements has been proven effective in boosting their work spirit and commitment to improving the quality of education. With such a leadership approach, principals are able to comprehensively enhance teacher performance, which ultimately has a positive impact on the quality of learning in elementary schools.

Electronic money laundering has become a critical issue as a form of cybercrime. Advances in technology demonstrate that digital forensic applications, particularly those utilizing smartphones, can be employed to uncover digital traces of money laundering transactions. This study aims to analyze the relevance of existing legal frameworks, the effectiveness of smartphone forensic techniques, and the challenges faced in their implementation in Indonesia. Based on a review of the literature and regulatory analysis, it was found that legal frameworks such as UU No. 8 of 2010 on the Prevention and Eradication of Money Laundering (TPPU) and UU No. 19 of 2016 on Information and Electronic Transactions (ITE) provide an adequate legal foundation. However, gaps in implementation, such as limited human and technological resources, remain significant obstacles. Forensic techniques, including metadata analysis and device extraction, have shown great potential in identifying the flow of illicit funds. Nonetheless, their application is hindered by data confidentiality and the lack of uniform technical standards. Given the increasing complexity of digital crimes, an integrated approach is required, combining regulatory strengthening with technological capacity building, to enhance the effectiveness of smartphone forensics in addressing electronic money laundering.

Increased textile industry production increases water pollution, especially rhodamine B dyes that are difficult to degrade. Global efforts to reduce water pollution through the adsorption process have been carried out with various adsorbents, the utilization of bottom ash from palm oil mill boiler combustion waste is still very minimal. This study examines the effect of contact time and bottom ash adsorbent mass on the adsorption capacity and absorption efficiency of rhodamine B using a fixed bed column adsorption process. The results showed that the longer the adsorption time, the higher the absorption efficiency. In the rhodamine B adsorption process, the best absorption efficiency was 98.308% at 10 cm bed height for 120 minutes and the best absorption capacity was 0.474 mg/g at 12 cm bed height for 150 minutes. The R2 price of Langmuir isotherm was 0.9999. FTIR analysis showed the presence of -OH, C-H, C=C and C-O functional groups that play a role in the adsorption process. The surface area of bottom ash from SAA test was 94.517 m2 /g. The SEM-EDX test analysis results had dominant elements of C, O and Si which showed good adsorption activity. From the results of the study that bottom ash from the combustion of oil palm mill boilers can be used as an effective adsorbent in reducing rhodamine B.
