Smoking behavior is a modifiable risk factor for hypertension, with hypertension prevalence generally increasing alongside higher cigarette consumption and longer smoking duration. Research on hypertension prevalence among productive-age smokers in Indonesia using national-scale data remains scarce in Indonesian publications. This study aims to analyze factors influencing hypertension among productive-age smokers in Indonesia in 2015, utilizing data from the Indonesia Family Life Survey (IFLS) 2015. The research employs a quantitative design with an analytical observational approach using a cross-sectional study. The sample comprises 10,677 productive-age smokers in Indonesia, selected via multi-stage random sampling across 32 provinces in 2015. Independent variables include age, gender, employment status, work region, cigarettes smoked, smoking duration, and daily cigarette consumption, while the dependent variable is hypertension. Hypertension prevalence among productive-age smokers in Indonesia in 2015 reached 8.53%, with significant predictors including age ≥36 years, female gender, employment status, smoking intensity of 21–30 or >31 cigarettes/day, and smoking duration >16 years—reflecting multifactorial interactions of biological, behavioral, and socioeconomic factors. Accordingly, recommendations include routine screening at primary health centers for at-risk groups, tobacco control programs based on dose-duration, economic empowerment for the unemployed, intensive screening with lifestyle counseling by healthcare providers, and longitudinal designs for future causal studies.

This study aims to examine the relationship between family support and depression levels among the elderly in Pejuang Village, Bekasi City, through a descriptive-narrative literature review. The review analyzed relevant scientific articles discussing family support, social support, and depression in older adults. Literature was selected based on the suitability of the elderly population, the presence of family or social support variables, and the measurement of depressive symptoms or depression levels. The analysis compared each article’s objectives, research design, respondent characteristics, instruments, findings, and conclusions. The results indicate that most studies found a relationship between family support or social support and depression among the elderly. Adequate family support, including emotional, instrumental, informational, and appraisal support, helps older adults feel cared for, valued, secure, and better able to adapt to the aging process. Preliminary findings at the Elderly Posyandu in Pejuang Village also show variations in family support and depression levels among elderly participants. Conversely, limited family support may increase loneliness, psychological distress, and depressive symptoms. Therefore, family support functions as a protective factor in reducing depression risk among older adults. Strengthening the involvement of families, health workers, and elderly posyandu cadres is necessary as a promotive and preventive strategy to maintain psychological well-being through education, early detection, and sustainable community-based assistance for vulnerable elderly groups living in community and family environments.

Hypertension is a major public health concern with a high prevalence and a significant risk of complications if left uncontrolled. Effective management requires not only pharmacological treatment but also non-pharmacological approaches and active family involvement. One potential non-pharmacological therapy is the use of celery (Apium graveolens), which is believed to lower blood pressure. This study aimed to evaluate the effectiveness of family education combined with celery decoction administration in reducing blood pressure among patients with hypertension. A descriptive case study design was employed using a family nursing care approach over three home visits, each lasting 30–45 minutes. The intervention included health education on hypertension and a demonstration of how to prepare and administer celery decoction, which was consumed twice daily. Data were collected through interviews, observation, and blood pressure measurements. The results showed a reduction in blood pressure from 159/90 mmHg to 130/80 mmHg, along with a decrease in symptoms such as headaches and dizziness. In addition, there was an improvement in family knowledge, caregiving skills, and the ability to modify the home environment. In conclusion, family-based education combined with the administration of celery decoction appears to be effective in reducing blood pressure and enhancing the family’s role in managing hypertension.

Indonesia, as a tropical country, is exposed to high levels of ultraviolet (UV) radiation, increasing the risk of skin damage. Sunscreen is widely used as a protective measure indicated by the Sun Protection Factor (SPF) value. This study aimed to evaluate the effect of active ingredient variations on SPF values and other influencing factors. A literature review with a descriptive-comparative approach was conducted using research articles published between 2021 and 2026 from Google Scholar, PubMed, ScienceDirect, and Elsevier. A total of seven eligible articles were analyzed. The results showed that the type of active ingredients, concentration, combination of ingredients, and dosage form significantly influence SPF values. Natural ingredients generally produce low to moderate SPF values, while combinations of active ingredients result in significantly higher SPF due to synergistic effects. Increasing the concentration of active ingredients also leads to higher SPF values. Additionally, dosage forms such as creams, serums, sunscreen powder and foundations affect sunscreen effectiveness through their film-forming ability on the skin. In conclusion, the combination of active ingredients and higher concentrations provides more optimal protection against UV radiation.

Sectio caesarea is a common surgical procedure to deliver a baby when normal delivery is not possible or risky. Postoperatively, patients often experience acute pain that can interfere with the recovery process. The benson relaxation technique is a nonpharmacological method that has been shown to be effective in reducing pain through a relaxation and patient confidence approach. This study uses a case study approach on Mrs. T, a post-sectio caesarea patient at Harapan Bunda Hospital, Batam City. Nursing care is carried out comprehensively for three days, including assessment, diagnosis, intervention, implementation, and evaluation. The main intervention was the administration of benzone relaxation techniques for 10–15 minutes every day. After three days of applying the Benson relaxation technique, Mrs. T's pain intensity decreased from a scale of 6 (moderate pain) to a scale of 2 (mild pain). Patients show increased comfort, ability to be active, and decreased expressions of pain such as grimacing. These results support previous findings that benzon relaxation is effective as a nonpharmacological therapy in reducing postoperative pain. This technique can be a safe and easy-to-apply alternative in nursing practice, especially for post-sectio caesarean patients.

This study examines customer churn prediction in subscription-based telecommunications from a digital marketing perspective using machine learning. The analysis utilizes a secondary dataset of 7,043 customer records that simulate behavioral, contractual, and financial attributes commonly found in telecom services. Three classification algorithms Logistic Regression, Random Forest, and Gradient Boosting are applied to model churn behavior. Data preprocessing includes handling missing values, encoding categorical variables, and splitting data into training and testing sets. Model performance is evaluated using accuracy, recall, and ROC-AUC, with emphasis on recall due to its importance in identifying at-risk customers. The results show that Gradient Boosting achieves the highest overall performance with an ROC-AUC of 0.84, while Logistic Regression provides relatively higher recall. Key drivers of churn include short-term contracts, higher monthly charges, and lower service engagement. However, recall remains moderate, indicating limitations in capturing complex behavioral factors. These findings suggest the need to combine predictive models with behavioral insights and highlight the importance of early customer engagement and long-term retention strategies.

Individual behavioral factors are critical determinants of organizational effectiveness and a vital component of modern organizational diagnosis. This study aims to identify and map individual behavioral factors as strategic indicators in organizational diagnosis using a Systematic Literature Review (SLR) approach guided by PRISMA 2020. Analysis of ten selected articles reveals that organizational effectiveness in the digital transformation era is driven by a reciprocal equilibrium between an individual's cognitive infrastructure and volatile work environment demands. The findings synthesize these behaviors into four strategic clusters: psychological well-being as primary infrastructure, digital structural support audits, justice and trust equilibrium, and psychological contract synchronization. This research provides tactical implications for Human Capital practitioners to transform annual diagnostic methodologies toward the implementation of monthly pulse surveys to detect fluctuations in well-being and disengagement intentions in real-time. This predictive diagnostic step is essential to mitigate turnover risks and design precise institutional interventions in hybrid work ecosystems.

Ballast water plays a crucial role in maintaining ship stability during shipping, but it also carries environmental and human health risks due to the heavy metals it carries. This study aims to examine the health risks posed by exposure to heavy metals in ballast water and to assess the effectiveness of management practices implemented in the maritime industry. Using a literature review method, this study examines various scientific sources related to the content of heavy metals such as lead (Pb), cadmium (Cd), copper (Cu), and zinc (Zn) in ballast water, as well as their impacts on human health and marine ecosystems. The results indicate that heavy metals in ballast water can cause long-term toxic effects such as neurological disorders, kidney damage, and respiratory and reproductive disorders. The greatest risk is experienced by maritime workers who are directly exposed through inhalation or skin contact during the ballast water sampling and processing process. To minimize these risks, strict work safety protocols, improved ballast water treatment technology, and regular monitoring of heavy metal levels are required. Thus, this study emphasizes the importance of strengthening ballast water management policies and practices that are oriented towards human health and environmental sustainability.  

Urban development has resulted in an increase in impermeable surfaces, increasing the risk of runoff inundating the road network. This situation occurs in the drainage system on Jl. Letjend S. Parman, Jl. Emo Kurniaatmaja, and Jl. Pulau Banda, Pasirkareumbi Village, Subang Regency. This study aims to evaluate the hydraulic performance of existing channels and develop redesign guidelines to reduce the risk of local flooding. The methods used include hydrological analysis of daily maximum rainfall data from the Subang rainfall station, rainfall frequency analysis using the Generalized Extreme Value (GEV) distribution, Intensity-Duration-Frequency (IDF) curves, and hydrological and hydraulic simulations using the Storm Water Management Model (SWMM). Model parameters include sub catchment area, rainfall intensity, time of concentration, infiltration using the Curve Number method, channel dimensions, cross-sectional shape, channel material, and the Manning coefficient. The results indicate that the GEV distribution provides a good fit for determining design rainfall. Based on the typology of a metropolitan city and a catchment area of ​​26.04 ha, the modeling period is 2 to 5 years. The SWMM simulation results indicate that some channel segments have very high flow velocities, potentially causing scour, while other segments have very low velocities, potentially causing sedimentation. This confirms the need for evaluation and restructuring of channel dimensions and slopes to improve the hydraulic performance of road drainage and reduce localized flooding.
