Infectious diseases remain a dynamic and evolving public health threat, requiring data-driven approaches for early detection and targeted policy planning. This study aims to model spatio-temporal trends and clustering patterns of HIV transmission in Bogor Regency during the period 2020–2023 by utilizing a combination of unsupervised and supervised machine learning techniques. The dataset was obtained from the Bogor Regency Health Office and includes annual data on the number of HIV cases across 40 sub-districts. The research methodology consists of data preprocessing stages, clustering using the K-Means algorithm, and classification using a Decision Tree model. The preprocessing steps include data integration, attribute selection, temporal aggregation, handling of missing data, and normalization using Z-score. K-Means clustering is applied to identify hidden patterns in the development of HIV cases, resulting in three distinct clusters based on multi-year trends. The resulting cluster labels are then used as target classes in the supervised classification process. The Decision Tree classification model demonstrates high accuracy in predicting cluster membership, indicating a strong relationship between the temporal patterns of HIV cases and cluster identity. The integration of clustering and classification techniques provides a robust analytical framework for understanding the dynamics of HIV transmission, while also supporting the formulation of more precise, evidence-based, and region-specific public health interventions.

Preterm birth remains a significant public health concern due to its contribution to neonatal morbidity and mortality worldwide. Among the various risk factors, maternal infections—particularly sexually transmitted infections (STIs)—have been identified as preventable yet critical determinants of premature delivery. This study aimed to examine the relationship between STIs and preterm birth among mothers receiving care at Tomalou Primary Health Care Center. A cross-sectional analytical design was employed, involving 30 postpartum mothers whose medical records and antenatal care data were available. Data on STI status and birth outcomes were collected from health center records and laboratory results, while maternal demographic and obstetric characteristics were also documented. Results indicated that 40% of participants were diagnosed with STIs during pregnancy, and 33.3% experienced preterm birth. Chi-square analysis revealed a significant association between maternal STI status and preterm delivery (p = 0.003). Logistic regression demonstrated that mothers with STIs were sixteen times more likely to deliver prematurely compared to uninfected mothers (OR = 16.0; 95% CI: 2.45–104.3; p = 0.002). These findings suggest that STIs represent a substantial risk factor for preterm birth, even among mothers with adequate antenatal care attendance. Early detection, timely treatment, and comprehensive reproductive health education are recommended to reduce infection-related adverse outcomes. Strengthening STI screening and management within primary healthcare settings is essential to improve maternal and neonatal health outcomes. This study provides evidence for the importance of integrating infection prevention strategies into routine antenatal care to mitigate the risk of premature delivery.

Financial management, both in public and private organizations, is highly vulnerable to fraud and misappropriation of funds. The risk of fraud in financial reporting not only jeopardizes an organization's long-term financial health but also damages the reputation and trust of stakeholders. Professional ethics and integrity are key factors in ensuring good, efficient, and effective financial governance. Weak internalization of professional ethical values ​​among financial practitioners, such as manipulation of financial reports and unauthorized use of official funds, is often a major cause of misappropriation of funds. These cases can significantly harm an organization, as seen in violations of codes of ethics in various large companies. Therefore, strengthening professional ethics in financial management practices is crucial to prevent misappropriation of funds, fraud, or financial manipulation. A strong internal control system, coupled with a good ethical culture, can play a significant role in preventing and detecting these conditions. This study aims to identify factors that support and hinder the implementation of professional ethics in financial management and provide recommendations for improving integrity and accountability in fund management. It is hoped that the results of this study will help organizations strengthen governance, increase transparency, and reduce the risk of fraud through better implementation of professional ethics.

Background: Stunting remains a major public health concern in Indonesia, affecting children’s growth, development, and long-term health outcomes (Sari, 2020). Early childhood stunting can lead to cognitive delays, poor school performance, reduced productivity in adulthood, and increased risk of chronic diseases (Hapsari & Wulandari, 2019). Understanding the interaction of demographic, socioeconomic, and health-related factors is essential to reduce stunting prevalence and improve child health outcomes (Yuliani, 2019). Objective: This study aimed to analyze the factors influencing the incidence of stunting among children attending the Sagerat Public Health Center in Bitung City. Methods: A quantitative, observational study with a cross-sectional design was conducted. Thirty children were selected using purposive sampling based on inclusion criteria such as age under five years and available anthropometric data. The Wilcoxon signed-rank test was applied to examine the relationship between these factors and stunting incidence, with a significance level set at p < 0.05. Results: The analysis showed that 30 children (100%) in the study were at risk of stunting based on height-for-age measurements, with 20 children (90%) confirmed as stunted and 10 children (10%) having normal height. These results suggest that maternal education, socioeconomic status, nutrition, and access to healthcare are strongly associated with stunting in this population. Conclusion: Factors such as maternal education, socioeconomic status, dietary intake, and access to healthcare significantly influence the incidence of stunting among children at the Sagerat Public Health Center. Comprehensive community-based programs are recommended to reduce stunting prevalence and improve long-term health outcomes for children.
