The study is an explanatory sequential research design where Phase I of the study is a quantitative research design in descriptive cross-sectional correlational approach. It was further explored in the Phase II which is the qualitative research design in descriptive phenomenological approach. In the Phase I of the study, 210 respondents participated in an online survey consisted of questionnaires for workplace violence, quality of work-life and job satisfaction. It showed insignificant values with P&gt;0.05 level, this means regardless of workplace violence experienced by some, the quality of work-life, and the job satisfaction of the staff nurses remains independent to each other. After analyzing the data, 15 respondents were interviewed to further explain the pragmatic philosophy in understanding the respondent’s perspectives and pursuit. Employing Colaizzi’s Method for data analysis, it has revealed 5 Major themes which are Predisposing factors on Workplace Violence, Actions of Workplace Violence, Resolution of the Victim, A Compassionate and Fulfilled Nurse, and Professional Growth and Career Stability. An interventional development variant was developed based on the 5 major themes entitled PreP for WV or the Prevention Plan for Workplace Violence. It is further recommended in the study for a program that focuses leadership and administrative program for managerial levels in nursing department to elevate prevention practices on workplace violence.</p> Adrian N., Palma Palma Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/503 Sun, 01 Feb 2026 00:00:00 +0700 Mobilization and Massage as a Prevention Against Pressure Ulcers: Quasi Experimental Study https://ejournal.stikesjayc.id/index.php/isgh/article/view/504 <p>Bed rest is a condition in which a patient is unable to move and must lie down for about 24 hours. One negative physical impact is damage to skin integrity, commonly known as pressure sores or decubitus ulcers. Efforts to address this problem include mobilization and massage therapy. Mobilization involves changing the patient's position at specific intervals as part of nursing intervention, while massage improves blood circulation. These actions can prevent pressure ulcers. Research was conducted to determine the effect of mobilization and massage on the risk of pressure ulcers in bedridden patients at Dustira Hospital in Cimahi, Indonesia. This research design is a quasi-experiment with a nonequivalent control group. The population consists of all bedridden patients, and the total sample is 62 people. There are 31 patients in the intervention group and 31 patients in the control group. Purposive sampling was used for the sample selection. Pressure ulcer risk was assessed using the Braden scale. After testing the normality of the data using the Shapiro-Wilk test (p &lt; 0.005), the results were analyzed using nonparametric tests namely the Wilcoxon and Mann-Whitney tests. After treatment, the mean score was 40.97 in the intervention group and 22.03 in the control group. The results showed a significant difference in pressure ulcer risk between the two groups after the intervention (p-value = 0.000). This study emphasizes the importance of incorporating pressure ulcer prevention for bedridden or immobilized patients into routine care in regular wards, intensive care units, and other settings where patients are bedridden for extended periods. This approach supports continuous care by addressing the physical and mental needs of patients. Additionally, the findings of this study will serve as the basis for evidence-based interventions to improve the quality of nursing services in hospitals. Furthermore, collaboration among healthcare teams, including doctors, nurses, nutritionists, and others, is essential to optimize care for bedridden patients, regardless of their underlying conditions.</p> Lee Wan Ling, Musri Musri, Ritha Melanie, Putri Dwi N, Kiki Gustryanti Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/504 Sun, 01 Feb 2026 00:00:00 +0700 Artificial Intellegence in Laboratory Health Care: Machine Learning in Bacterial Identification https://ejournal.stikesjayc.id/index.php/isgh/article/view/505 <p>Accurately identifying bacterial species is essential in diagnostic microbiology, where biochemical testing remains a primary method for classification. These tests assess how microorganisms metabolize specific substrates, producing measurable reactions that indicate species-level traits. Although automated systems have improved interpretation through probability-based scoring, misidentification still occurs due to the natural variability of bacterial phenotypes. To address this challenge, the study introduces PyBact, an open-source Python-based software designed to simulate realistic bacterial biochemical profiles for research and educational purposes. PyBact generates binary datasets representing biochemical test results by using probability values derived from authoritative microbiology references, including the Manual of Clinical Microbiology. For each species, the program creates a user-defined number of simulated strains and assigns positive or negative test outcomes based on known frequencies. This probabilistic method faithfully reflects biological diversity rather than relying on fixed, idealized profiles. The resulting data matrices are compatible with machine learning workflows. To evaluate the tool, researchers simulated 100 strains for each species in two datasets: 12 Vibrio species (1,200 strains) and 134 Enterobacteriaceae species (13,400 strains). These datasets were analyzed using Weka with three machine learning models—Decision Tree (J48), Naive Bayes, and SVM—under 10-fold cross-validation. The classifiers performed exceptionally well, achieving up to 100% accuracy for Vibrio and above 91% for Enterobacteriaceae. Overall, the study demonstrates that PyBact effectively produces biologically meaningful simulated datasets that support highly accurate machine learning–based bacterial identification. The software also serves as a valuable educational resource and is freely available under the Open Software License.</p> Likit Preeyanon, Charlchalerms Isarankura Na Aayudha, Prachayasittikul V, Natasenamat C Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/505 Sun, 01 Feb 2026 00:00:00 +0700 Ethical, Effective, Empowered: Policy and Practice for Tomorrow’s Health Professionals https://ejournal.stikesjayc.id/index.php/isgh/article/view/506 <p>As Artificial Intelligence (AI) rapidly expands across healthcare and higher education, universities face urgent questions about safety, ethics, and AI's impact on student learning and wellbeing. This presentation explores the real benefits and risks of AI adoption in health-profession programs, citing emerging global evidence of decreased peer connection, increased accuracy concerns, and student anxiety about academic integrity.

Chemotherapy is a common treatment. Chemotherapy has both physical and psychological effects. One psychological impact is anxiety. Anxiety in children increases an exaggerated response to painful stimuli and can lead to refusal of treatment, thus impacting the treatment. Anxiety in children can be treated with lemon oil aromatherapy. Lemon oil aromatherapy is a non-pharmacological technique aimed at preventing anxiety in children. The aim of this study was to determine the effect of lemon oil aromatherapy intervention on the anxiety of school-aged children undergoing chemotherapy at a private hospital in Bandung. The study used a quasi-experimental design. The sample consisted of school-aged children. Consecutive sampling was used, with 21 children selected. Data collection involved administering aromatherapy through a diffuser as much as 2 drops of lemon oil dissolved in 100 ml of water, given once before and after chemotherapy for 15 minutes. Anxiety was measured before and after the intervention using the Zung Self-Anxiety Rating Scale (ZSAS) questionnaire, combined with an artificial intelligence based emotimeter to analyze facial expressions more accurately. Data analysis used marginal homogeneity test, found that anxiety before the intervention was mostly severe anxiety (60-74) and after the intervention changed to normal (&lt;45). The statistical test yielded a p-value of 0.001, indicating that the lemon oil aromatherapy intervention had an effect on children's anxiety. Pediatric nurse should provide non-pharmacological interventions, such as aromatherapy, to treat anxiety in children undergoing chemotherapy and using appropriate measurement tools to assess anxiety.</p> Nunung Nurjanah, Siti Dewi Rahmayanti, Chatarina Suryaningsih Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/508 Sun, 01 Feb 2026 00:00:00 +0700 The Relationship between Long suffering and medication adherence with Quality-of-Life in Patients with Type 2 Diabetes Mellitus https://ejournal.stikesjayc.id/index.php/isgh/article/view/509 <p>Type 2 diabetes mellitus (T2DM) is a long-term condition that cannot be completely cured, it can affect health and quality of life (QOL). This study aims to determine the relationship between long suffering and medication adherence with quality of life among patients with T2DM. Research design used cross sectional study, samples are patients with T2DM at Cibereuem and Cigugur Tengah Public Health Center, Cimahi West Java, as many as 115 patients. The independent variables were long suffering measures in years since diagnosis, medication adherence using MMAS-8, while the dependent variable is QOL for diabetes used the Diabetes Quality of Life-Brief Clinical Inventory (DQOL-BCI). Data analysis using chi-square, the p-value was as a significant test, with a significance level (alpha)=0.05. The result of this study showed that the variables were significant with quality-of-life patient T2DM are long suffering (p value= 0.01; OR= 3.54, (5%CI: 1.40-8.92), medication adherence (p value= 0.01; OR= 3.54, (5%CI: 1.40-8.92). The results highlight the importance of addressing long-term illness duration and promoting adherence to medication to enhance patients’ quality of life. Interventions targeting patients with T2DM who have been living with the disease for more than five years should focus on improving medication adherence to achieve better QOL outcomes.</p> Dyan Kunthi Nugrahaeni, Novie Elvinawaty Mauliku, Teguh Akbar Budiana Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/509 Sun, 01 Feb 2026 00:00:00 +0700 The Relationship Between Viral Load and Neutrophil Lymphocyte Ratio in HIV Patients Receiving Antiretroviral Therapy https://ejournal.stikesjayc.id/index.php/isgh/article/view/510 <p>Human Immunodeficiency Virus (HIV) is a virus that attacks the immune system and can progress to Acquired Immune Deficiency Syndrome (AIDS). Currently, HIV/AIDS remains incurable; however, viral replication can be controlled through Antiretroviral (ARV) therapy. The effectiveness of ARV is typically monitored through viral load testing. Several studies have also highlighted the Neutrophil Lymphocyte Ratio (NLR) as a biomarker that may reflect the severity of viral infection. This study aimed to examine the relationship between viral load and NLR in HIV patients undergoing ARV therapy, as well as to assess the influence of ARV therapy duration on these parameters. A quantitative approach with a cross-sectional design was employed, involving 50 HIV patients receiving ARV therapy at Bayu Asih Regional General Hospital, Purwakarta Regency. Viral load data were obtained from laboratory testing using the GeneXpert Rapid Molecular Test, while NLR was derived from complete blood count results measured with the Yumizen H500 Automatic Hematology Analyzer. Data analysis was conducted using the Chi-Square test. The results demonstrated a significant relationship between viral load and NLR (p = 0.000). In contrast, no significant relationship was found between viral load and the duration of ARV therapy (p = 0.246) or between NLR and the duration of ARV therapy (p = 0.078). Therefore, it can be concluded that an increase in viral load is associated with an increase in NLR, suggesting that NLR may serve as an inflammatory marker in HIV patients undergoing ARV therapy, whereas the duration of ARV therapy does not appear to affect these parameters.</p> Gina Rifa’atul Mahmudah, Rina Rina, Patricia Gita Naully Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/510 Sun, 01 Feb 2026 00:00:00 +0700 Mother's Knowledge of MP-ASI by Early MP-ASI Giving to Mothers Who Have Babies 0-12 Months in the Working Area of the Padasuka Cimahi Health Center: Study Corellation https://ejournal.stikesjayc.id/index.php/isgh/article/view/511 <p>Complementary foods are foods and drinks other than breast milk that are given to infants when they are 6 months old. Giving food and drink other than breast milk to babies before 6 months of age is called early complementary feeding. Knowledge is the things that a person gets that have been captured through the five senses by that person. The prevalence of infants who have been given early complementary foods in Cimahi city is 40%. The purpose of this research was to see the description of mothers knowledge, early complementary feeding, and the relationship between mothers knowledge and early complementary feeding in the working area of Padasuka Cimahi Health Center. This study uses Analytical Survey research method with Cross Sectional design. The sample technique used was Total Sampling. The sample in this study were mothers who had babies aged 0-12 months totaling 92 mothers in the Padasuka Cimahi Health Center working area. Univariate analysis used frequency distribution and bivariate using Chi Square analysis. Data collection methods using questionnaires. The results of this study indicate that there is a relationship between maternal knowledge about complementary foods and early complementary feeding with the results of the Chi Square test with a p-value of 0.001 &lt;0.05. It is suggested that local health services can increase health promotion about complementary foods in the area to be used as additional information for mothers who are preparing to give complementary foods and who have given complementary foods to their babies, so that mothers can increase their knowledge of complementary foods.</p> Dyna Apriany, Siti Dewi Rahmayanti, Ai Setianah Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/511 Sun, 01 Feb 2026 00:00:00 +0700 Risk Factors Associated with Mental Health among Construction Workers at PT PP (Persero) Tbk in the KH Mohammad Thohir Regional General Hospital Project, Lampung https://ejournal.stikesjayc.id/index.php/isgh/article/view/512 <p>This study investigates the risk factors associated with mental health among construction workers at the RSUD KH Mohammad Thohir project, Lampung. A cross-sectional approach was applied involving 135 workers selected through total sampling. Data were collected using validated questionnaires, including Job Demands–Resources indicators and the Self-Reporting Questionnaire (SRQ-20). Univariate, bivariate, and multivariate analyses were performed to identify the relationship between job demands, job resources, work duration, working hours, and mental health status. The results showed that more than half of the workers (51,9%) experienced mental health problems. Job demands demonstrated a significant relationship with mental health (p = 0,001), where workers with high job demands had a higher proportion of psychological distress (68,9%). Job resources were also significantly related to mental health (p = 0,000), with low job resources increasing the likelihood of mental health issues. Working hours and work duration showed borderline and significant associations, respectively. Multivariate analysis indicated that education, job resources, and job demands were the most influential predictors of mental health. The study concludes that psychosocial work conditions play an essential role in influencing workers’ psychological well-being, underscoring the need for targeted interventions to improve mental health outcomes among construction workers.</p> Erna Wahyuni Andawati, Novie E.

In conclusion, service quality plays a critical role in shaping the satisfaction of BPJS outpatients at RSUD Al Ihsan, highlighting the importance of improving administrative flow, responsiveness, and facility support to enhance patient experience and strengthen trust in public healthcare services.</p> Neti Sitorus, Tri Ardayani, Ade Syaiful Rohman Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/513 Sun, 01 Feb 2026 00:00:00 +0700 Factors Influencing Antihypertensive Medication Adherence Among Elderly Patients: A Cross-Sectional Study in Sesayap Hilir, North Kalimantan https://ejournal.stikesjayc.id/index.php/isgh/article/view/514 <p>Hypertension is a chronic condition frequently accompanied by low medication adherence in older adults, contributing to elevated risks of cardiovascular complications. This study aimed to identify the factors influencing medication adherence among elderly patients with hypertension in the working area of the Sesayap Hilir Public Health Center, Tana Tidung Regency. A cross-sectional design was applied involving 258 participants selected through purposive sampling. Data were collected using the 8-item Morisky Medication Adherence Scale (MMAS-8) and a structured questionnaire with researcher developed items to evaluate predisposing, enabling, and reinforcing factors, and were analyzed using chi-square tests and factor analysis. Most participants demonstrated low adherence (81%), had primary level education, reported family income below the regional minimum wage, and had lived with hypertension for at least three years. No significant associations were found between medication adherence and education level (p = 0.388), employment status (p = 0.364), family income (p = 0.082), or hypertension duration (p = 0.657). In contrast, knowledge (p &lt; 0.001), family support (p &lt; 0.001; PR = 24.65), and motivation (p &lt; 0.001; PR = 21.93) were strongly associated with adherence. Factor analysis identified two significant components: psychosocial resources (knowledge, family support, motivation) and demographic–disease factors (education, occupation, illness duration), which together explained 64.45% of the total variance. These findings indicate that psychosocial resources are the predominant determinants of medication adherence among elderly patients with hypertension. Interventions at the primary care level should therefore prioritize strengthening health literacy, enhancing family involvement, and maintaining patient motivation to support long-term treatment adherence.</p> Eka Shofinah, Ayu Laili Rahmiyati, Dyan Kunthi Nugrahaeni Copyright (c) 2025 International Seminar on Global Health https://ejournal.stikesjayc.id/index.php/isgh/article/view/514 Sun, 01 Feb 2026 00:00:00 +0700 The Effect of Combined Consumption of Iron Tablets with Vitamin C (Ascorbic Acid) Tablets and Guava Fruit on Hemoglobin Levels in Adolescent Girls with Anemia at the As-Saruniyah Health Center in Cianjur Regency in 2025 https://ejournal.stikesjayc.id/index.php/isgh/article/view/515 <p>Anemia often affects adolescent girls due to psychological conditions that often cause stress, menstruation, or unhealthy lifestyles, especially in terms of nutritional needs.
