This study aims to analyze the effect of service quality on patient loyalty through patient satisfaction at the Dental and Oral Clinic of Mitra Kasih Hospital Cimahi. The research is based on a significant decline in the number of patients in recent years, especially during the COVID-19 pandemic, as well as complaints about the quality of hospital services. A quantitative approach with descriptive and verificative design was applied, involving service quality (X), patient satisfaction (Y), and patient loyalty (Z) variables. Data were collected through structured questionnaires distributed to a sample of patients and analyzed using path analysis. The results indicate that service quality has a positive and significant effect on patient satisfaction (0,875), which in turn influences patient loyalty (0,595). Patient satisfaction also influences on patient loyalty (0.733). Moreover, there is a significant indirect effect of service quality on patient loyalty through patient satisfaction as an intervening variable (1,9876). The key factors contributing to patient satisfaction include reliability, responsiveness, assurance, empathy, and tangible aspects of the service.

Eman Salim — 2025-06-30

This cross-sectional study, conducted in five secondary schools in White Nile State, Central Sudan, aims to assess the seroprevalence of Hepatitis B Virus (HBV) among students aged 14-20 years. Utilizing a sample of 384 students, the study employs the Enzyme-Linked Immunosorbent Assay (ELISA) technique to detect HBV surface antigens (HBsAg). The results reveal a high prevalence rate of 49%, with significant correlations between HBV infection and factors such as gender, marital status, blood transfusion history, family history of HBV, and vaccination status. Notably, female students exhibit a higher prevalence rate (55%) compared to male students (45%). Married students show a 100% prevalence rate, indicating a strong link between marital status and HBV infection. Additionally, students with a history of blood transfusions and those with family histories of HBV are more likely to be infected. Vaccination history emerges as a critical factor, with vaccinated students displaying lower infection rates, underscoring the importance of vaccination programs. These findings emphasize the need for enhanced HBV awareness, regular screening, and vaccination campaigns to mitigate the virus's spread among young populations in similar settings, ultimately contributing to better public health outcomes

Antibacterial Properties of Turmeric Oil Nanoemulsion

Yan Hendrika — 2025-07-08

Turmeric oil is an essential oil extracted from Curcuma domestica rhizome, containing active compounds like turmerone, atlantone, and zingiberone, with various pharmacological activities. This study aimed to evaluate the antibacterial activity of turmeric oil nanoemulsion formulations (F1, F2, F3) against Staphylococcus aureus and Escherichia coli. The nanoemulsions were characterized for organoleptic properties, pH, viscosity, stability, homogeneity, droplet size, and zeta potential. All formulas appeared as thick, yellow, aromatic liquids with good homogeneity, pH of 6.8–7.0, and showed no separation upon centrifugation. Droplet sizes were 23.2 nm (F1), 203.8 nm (F2), and 298.7 nm (F3), with zeta potentials of –18.5 mV, –13.4 mV, and –8.5 mV, respectively. Antibacterial tests using the diffusion method showed moderate activity with inhibition zones ranging from 5.0–9.8 mm. These findings indicate that turmeric oil nanoemulsions are physically stable and exhibit moderate antibacterial activity.

Family Coping Mechanisms in Response to Stunting Events in Toddlers in the Working Area of Pekanheran Health Center

Alice Rosy — 2025-07-10

Stunting remains a public health issue in Indonesia, with an estimated 27.7% of children under five years old experiencing stunting. The role of parents and family is very important in meeting the needs of children and providing them with good growth and development, so that children can live well. A positive family coping approach is very important. Without effective family coping mechanisms, the family's functions cannot be adequately achieved. Desa Air Jernih is a Stunting Locus Village in 2024. The purpose of this study is to determine the relationship between family coping mechanisms and the incidence of stunting in toddlers, using a total population technique involving 89 families with toddlers and employing three types of questionnaires: a respondent characteristic questionnaire, a toddler height measurement, and a parental coping mechanism questionnaire using the F-COPES instrument. Based on statistical testing using the chi-square method, a p-value of 0.282 was obtained, indicating that there is no relationship between family coping mechanisms and the incidence of stunting.
