Rosella is known to have many health benefits, such as boosting the immune system and regulating blood pressure. Based on a situation analysis, the lack of knowledge among students regarding the rosella plant is due to the absence of rosella plants in the school area. Additionally, there has never been a workshop at SDN Tlogosari Wetan 02 Semarang related to educating students about the use of rosella flower petals as a health tea by any party. The community service activity began with an introduction to the rosella plant to the students, followed by education on the use of herbal plants that contain antioxidants, in this case, the rosella flower. After that, the activity continued with training that involved the students in the process of making rosella tea. The results of this activity showed an increase in the students' knowledge about the importance of a healthy lifestyle and the students' skills in utilizing natural materials (rosella flower petals) to make health tea.

The development of the Smart City concept demands a reliable, flexible communication network infrastructure capable of covering the entire urban area. This study designs a wireless network based on mesh topology as a communication solution to support various Smart City applications. Mesh topology is chosen for its advantages in scalability, path redundancy, and fault tolerance. The research method involves designing a network simulation with varying numbers of nodes and testing performance parameters such as throughput, latency, and packet loss. Simulation results show that an increase in the number of nodes correlates with higher throughput, lower latency, and reduced packet loss. These findings indicate that mesh topology is highly suitable for meeting the real-time and stable connectivity needs of Smart City implementations. This network design is expected to serve as a foundation for future digital infrastructure development in smart cities.

This study discusses 5G network security regulations and policies from a national and international perspective, with a focus on the challenges and handling of global cyber threats. Given the cross-border threats, security and regulation are important issues in the implementation of 5G technology. The approach used is qualitative interpretive with additional limited experiments, including cyber attack simulations. The result of the study show that cyber policies in Indonesia are not yet fully coordinated, unlike countries such as the US, the European Union, and China which have more comprehensive regulations. Experiments prove that the implementation of protocols such as IPSec and TLS can reduce risks in 5G networks. Therefore, Indonesia is advised to form more integrated regulations that comply with international standards. This study also suggests further research in real scenarios and the development of a more in-depth policy evaluation system.

This research aims to see the results of activities to increase employee capacity through the disaster safe hospital (RSAB) program at Kilisuci Regional Hospital, Kediri City. Hospital preparedness plans are very important in ensuring the safety of the hospital environment and the actions that need to be taken to ensure health services remain available during a disaster situation. Kilisuci Regional Hospital does not yet have a preparedness plan that is documented, tested, and involves the surrounding community to be ready to face disasters. The methods used in this community empowerment activity include pretest-posttest, lecture-discussion, direct training/practice, observation and evaluation methods. The research results show that Disaster Management at the Kilisuci Regional Hospital is very necessary considering that Kediri City has a variety of potential disasters and is in an area that has potential threats from floods, fires, the Covid-19 pandemic, Mount Kelud eruptions, traffic accidents and earthquakes. There was an increase in pretest and posttest results of 14.60 points. It is felt that activities to strengthen employee capacity through the Hospital Disaster Plan (HDP) program need to be developed further because hospitals need more preparedness capacity in facing disasters or emergency situations and can support during hospital accreditation.

Social media has become a crucial part of modern life around the globe, providing users with various conveniences. However, its widespread use has also brought about new challenges, one of which is cyberbullying. This harmful issue can have serious emotional and physical effects on those targeted. Cyberbullying occurs in many areas, including sports, and soccer—a sport loved by millions—is no exception. Soccer players often face severe criticism, hate speech, and harassment on social media platforms. To tackle this problem, this study aims to create a strong model for detecting cyberbullying on the social media platform “X” using the Long Short-Term Memory (LSTM) method. By utilizing advanced machine learning techniques, the proposed model intends to identify and reduce instances of cyberbullying, helping to create a safer online space for athletes and the wider community.

This research aims to evaluate the level of usability and user satisfaction with the Amikom University Purwokerto student affairs website using the System Usability Scale (SUS) method. This method was chosen because of its simplicity in providing reliable and fast results through a survey based on 10 statements with a Likert scale. The research respondents were active students at Amikom University, Purwokerto, who were selected using a sampling method based on the Slovin formula with a total sample of 97 respondents. Data is collected through an online questionnaire that measures aspects of convenience, satisfaction and system reliability. The analysis results show an average SUS value of 58.85, which is classified in the Marginal Low category based on the interpretation of the SUS scale. These findings indicate that the website has not fully met user expectations in terms of usability, even though it provides relevant features and services. Therefore, improvements are needed in user interface elements, navigation, and design consistency to improve user experience. This research makes an important contribution to the development of information systems in higher education by identifying weaknesses that can be improved to achieve better efficiency and satisfaction.
