The rapid growth of Internet of Things (IoT) and edge computing technologies has introduced new security challenges due to the distributed, heterogeneous, and dynamic nature of these environments. Conventional static security mechanisms, such as rulebased authentication and fixed trust models, are often inadequate for addressing evolving threats and abnormal behaviors in largescale IoT systems. To overcome these limitations, this study proposes a machine learningbased trust evaluation framework for enhancing security in distributed IoT environments. The proposed approach dynamically assesses the trustworthiness of IoT nodes by analyzing behavioral and interactionbased features collected at the edge layer. Machine learning models are trained to classify nodes into trusted and malicious categories and continuously update trust values in response to changing network conditions. Based on the predicted trust levels, adaptive security decisions are enforced to allow or restrict node participation in data sharing and computation processes. A quantitative experimental evaluation is conducted using simulated distributed IoT scenarios that include both normal and malicious behaviors. The performance of the proposed framework is evaluated using standard metrics such as accuracy, precision, recall, F1score, and detection effectiveness, and is compared against conventional static trust and rulebased security mechanisms. The results demonstrate that the proposed machine learningbased trust evaluation approach achieves significantly higher detection accuracy and robustness while maintaining low computational overhead. Overall, the findings confirm that integrating machine learning into trust management provides an effective and scalable solution for securing distributed IoT systems under dynamic and adversarial conditions.

The rapid growth of cross-platform applications has significantly increased the volume and diversity of sensitive user data processed across heterogeneous and distributed environments. Personally identifiable information, device identifiers, behavioral data, and financial information are routinely collected to support personalization, analytics, and service optimization. While these practices enhance application functionality and user experience, they also introduce substantial privacy risks, including unauthorized data access, device fingerprint–based re-identification, cross-user data leakage, and large-scale data breaches. These risks are further amplified by distributed processing architectures and extensive third-party library integrations commonly used in modern cross-platform systems. This study aims to systematically analyze privacy issues in cross-platform applications by examining the types of sensitive data involved, identifying dominant privacy threats, and reviewing state-of-the-art privacy-preserving mitigation strategies. A systematic literature-based methodology was employed, focusing on recent Scopus-indexed journal articles, conference papers, and book chapters. The analysis synthesizes findings using thematic categorization and a conceptual research framework that maps sensitive data sources to privacy threats and corresponding mitigation mechanisms. The results indicate that privacy risks in cross-platform applications originate not only from external attacks but also from internal architectural weaknesses, such as flawed authorization logic and excessive data sharing across system components. Privacy-preserving techniques including differential privacy, federated learning, blockchain-based data governance, secure multi-party computation, and fine-grained access control mechanisms are shown to provide stronger privacy guarantees compared to conventional centralized approaches. However, these techniques also present trade-offs related to system complexity and performance. Overall, the study highlights the importance of adopting a multi-layered, privacy-by-design approach to ensure sustainable, trustworthy, and regulation-compliant cross-platform application development.

Anesthesia practice in Indonesia faces challenges related to the implementation of professional standards and ethics as well as legal issues that often arise. This study aims to examine the implementation of professional standards and ethics in anesthesia practice in Indonesia today and to identify legal issues that often occur and how to resolve them. This study uses a normative legal research method by analyzing primary and secondary legal materials. The results of the study indicate that although there are guidelines and codes of ethics that regulate anesthesia practice, their implementation in the field still faces obstacles such as lack of understanding of health workers, excessive workload, lack of support from hospital management, and less than optimal supervision and sanctions. Legal issues that often arise include negligence in administering anesthesia, lack of informed consent, violations of the professional code of ethics, and problems in the doctor-patient relationship. Efforts that have been made to overcome these problems include improving education and training, improving standard operating procedures, strengthening supervision and sanction mechanisms, developing non-litigation dispute resolution channels, improving communication and doctor-patient relationships, and increasing support from hospital management. However, these efforts are still not fully optimal and require further evaluation and improvement. The importance of individual awareness of each anesthesiologist to comply with professional standards and ethics and strengthening ethics education are also key factors. Close collaboration between various related parties is needed to improve the quality of anesthesia practice in Indonesia while prioritizing patient safety and welfare.

This study aims to conduct a literature review on previous research related to factors influencing employee turnover intention in human resource management. This research falls under the category of library research,. The analysis of theory and relationships between variables is carried out through journals obtained from sources such as Publish or Perish, Mendeley, Google Scholar, and e-books. The findings of the research indicate that employee competency levels have a positive impact on turnover intention, indicating that despite possessing high skills, factors such as employee motivation, salary satisfaction, and organizational climate also play a significant role in influencing turnover intention. Furthermore, work stress, organizational commitment, and job satisfaction were identified as factors having a negative impact on turnover intention. The study also underscores that a positive organizational culture can diminish turnover intention, emphasizing the need to consider other variables such as work environment, leadership style, and organizational commitment. Additionally, the research highlights emotional labor and burnout as significant factors, wherein heightened emotional exhaustion can amplify employees' inclination to leave their jobs. Subsequent research endeavors could explore contextual factors that may moderate or alter the relationship between the identified variables (such as competence, motivation, job satisfaction) and turnover intention.

Clean and healthy living behavior (PHBS) is a reflection of a person's lifestyle who always pays attention to and maintains their health. Pulmonary TB is an inflammatory disease of the lung parenchyma due to infection with the Mycobacterium tuberculosis bacteria. Schools have the potential to increase the incidence of pulmonary TB if students do not maintain personal and environmental hygiene. The aim of this community service is to educate students about clean and healthy living behavior for elementary school students, especially preventing TB transmission in Oelomin Village, Nekamese District, Kupang Regency. The activity was carried out at SDN 2 Tunfeu, Oelomin Village, where students from grades 1 to 6 were educated about preventing TB disease, how the disease is transmitted, how to behave in a clean and healthy lifestyle to avoid tuberculosis. Before the activity took place, students were given a questionnaire about tuberculosis to determine the level of student knowledge. Then practice the behavior of washing hands with soap at school. At the end of this activity, students were asked questions about preventing tuberculosis and how to wash their hands properly. After the activity is finished, students are given another questionnaire to measure student understanding. The results of this activity show that the percentage of students who are not good at carrying out PHBS practices for preventing pulmonary TB is more often found in the group with the poor knowledge category (52%) compared to the group with the good knowledge category (20%). Students' lack of knowledge about pulmonary TB and PHBS is that 75% of students do not know the symptoms of pulmonary TB, namely coughing for more than 3 weeks. As many as 66.5% of students did not know the cause of pulmonary TB, namely Mycobacterium tuberculosis infection. As many as 40% of respondents did not know about the transmission of pulmonary TB disease when sufferers sneezed and 54% did not know about the transmission of pulmonary TB disease when sufferers spoke. As an outcome of this activity, it is hoped that students will be able to implement clean and healthy living habits at home, as well as using masks when they are sick to prevent tuberculosis.
