The population of the study was all patients with Pulmonary TB and suspects, with a sample of 103 <br />respondents. <strong>Results:</strong> The majority of patients with Pulmonary TB were found in the average age group of 49 <br />years, with male sex (8.7%) and income ≤ minimum wage (48.5%). The incidence of pulmonary TB was <br />significantly related to occupancy density (p=0.011), ventilation area (p=0.041), lighting (p=0.043), humidity <br />(p=0.048), and temperature (p=0.044). Behavioral factors of contact history (0.010) and smoking habit <br />(p=0.040). Based on the results of the Chi-Square test, it was found that there was a significant relationship with <br />the incidence of pulmonary TB. <strong>Conclusion:</strong> The incidence of pulmonary TB was found in a small number <br />of people living in the work area of the Public Health Center in Palembang, namely occupancy density, <br />ventilation area, lighting, humidity, temperature, contact history, and smoking habits. Therefore, it is necessary to <br />make efforts for the community to maintain the home environment and implement Clean and healthy living.<br />Behavior (CHLB), and conduct early examinations for those who have a history of contact to prevent the <br />transmission of pulmonary TB.</p> Mardanila Mardanila Maksuk Maksuk Esti Sri Ananingsih Copyright (c) 2025 Epidemiological Journal of Indonesia https://creativecommons.org/licenses/by-nc-sa/4.0 2025-10-31 2025-10-31 4 2 47 56 10.70326/epidjrid.v4i2.47 https://journal.paei.or.id/eji/article/view/46 <p><strong>Background:</strong> Oranges (Citrus sinensis) are highly perishable fruits. Their preservation is of interest due to the global importance of reducing food spoilage. Cinnamon powder, a natural preservative, and sodium benzoate, a synthetic one, are both used in food preservation, yet their comparative efficacy in maintaining fruit quality is unclear. <strong>Methods:</strong> A controlled laboratory experiment was conducted using 5 groups of oranges subjected to 0.1% and 0.3% concentrations of cinnamon powder and sodium benzoate, and a control group. Parameters measured included mass change and pH stability over a 5-day refrigerated period. Quantitative data were collected daily, and statistical observations were made on moisture retention and pH changes. <strong>Results:</strong> Cinnamon powder (especially at 0.3%) showed the highest effectiveness in preserving fruit mass, with mean mass increases of 15.128% (0.1%) and 21.664% (0.3%). Sodium benzoate, by contrast, showed modest increase (5.542%) at 0.1% but a decrease (-1.966%) at 0.3%. pH levels across all samples remained relatively stable (4-5), indicating that neither preservative caused significant acidification. <strong>C</strong><strong>onclusion:</strong> Cinnamon powder, especially at higher concentrations, is more effective in preserving the moisture content of oranges compared to sodium benzoate. Sodium benzoate was slightly more consistent in maintaining pH but failed to prevent mass loss at higher concentrations.</p> Kaysan Faris Maulana Erni Purnasari Elisa Copyright (c) 2025 Epidemiological Journal of Indonesia https://creativecommons.org/licenses/by-nc-sa/4.0 2025-10-31 2025-10-31 4 2 57 61 https://journal.paei.or.id/eji/article/view/48 <p><strong>Background:</strong> Clean and Healthy Living Behaviors remain a problem, especially among elementary school children. This study aims to analyze clean and healthy living behaviors among elementary school children. <strong>Methods:</strong> This research is an analytical observational study with a cross-sectional design. Data were collected using a questionnaire through student interviews. Then, they were analyzed univariately, bivariately using the chi-square test, and multivariately using multiple logistic regression. <strong>Results:</strong> The research results showed that knowledge, facilities and infrastructure, information exposure, and the role of teachers and staff were good, but the majority of attitudes remained negative. All of these variables were significantly correlated, with two variables being the most dominant in determining Clean and Healthy Living Behavior: knowledge and facilities and infrastructure. <strong>C</strong><strong>onclusion: </strong>Clean and Healthy Living Behavior is significantly related to knowledge, attitudes, facilities and infrastructure, exposure to information, the role of teachers and the role of officers.</p> Memo Harry Sandra Maksuk Maksuk Ferly Oktriyedi Copyright (c) 2025 Epidemiological Journal of Indonesia https://creativecommons.org/licenses/by-nc-sa/4.0 2025-10-31 2025-10-31 4 2 62 69 https://journal.paei.or.id/eji/article/view/49 <div> <p><strong><span lang="EN-ID">Background:</span></strong><span lang="EN-ID"> Hypertension is a non-communicable disease often referred to as the "silent killer" due to its asymptomatic nature and potential to cause severe complications. In Indonesia, including the city of Palembang, the prevalence of hypertension continues to rise, highlighting the urgency of effective health education as a preventive measure.<strong>Objective:</strong> This study aims to evaluate the effectiveness of educational interventions delivered via video media in improving the knowledge, attitudes, and practices of hypertensive patients within the service area of the Pembina Community Health Center, Palembang.</span></p> </div> <div><strong><span lang="EN-US">Method:</span></strong></div> <div><span lang="EN-US"> A quasi-experimental design with a one-group pre-test and post-test approach was employed. A total of 109 respondents were selected using purposive sampling.

Data analysis was conducted using univariate and bivariate methods, including the Wilcoxon Signed-Rank Test. <strong>Results:</strong> The intervention significantly improved participants' knowledge, attitudes, and practices regarding hypertension management, as indicated by p-values ranging from 0.000 to 0.002. The mean knowledge score increased from 70.18 to 84.42, the mean attitude score from 84.95 to 89.43, and the mean practice score from 72.11 to 83.22. The percentage increases for each variable were 14.24% for knowledge, 4.48% for attitude, and 11.09% for behavior. <strong>Conclusion:</strong> The educational intervention using video media effectively enhanced the knowledge, attitude, and behavior of hypertensive patients, as evidenced by statistically significant improvements in all measured domains (p &lt; 0.05). <strong>Recommendation:</strong> Educational videos are recommended as an effective strategy for health promotion and hypertension prevention, as they provide clear, visual information that can support behavioral change among patients</span></div> Dwinisa Dea Racellyta Intan Kumalasari Faiza Yuniati Copyright (c) 2025 Epidemiological Journal of Indonesia https://creativecommons.org/licenses/by-nc-sa/4.0 2025-10-31 2025-10-31 4 2 70 79 https://journal.paei.or.id/eji/article/view/50 <p>Background: Diarrhea is one of the health problems that frequently occurs among elementary school children and can lead to serious consequences if not properly addressed. Preventive efforts through health education are essential, one of which is utilizing engaging and easily understandable learning media for children. Objective: This study aims to determine the effect of animated infographic video media on improving the knowledge and attitudes of third-grade students at SDN 118 Palembang in diarrhea prevention. Methods: The research design used was a quasi-experimental design with a one-group pretest-posttest approach. The study sample consisted of 59 students selected using a total sampling technique. The instruments used were knowledge and attitude questionnaires that had been tested for validity and reliability. Data were analyzed using the Wilcoxon Signed Rank Test. Results: The study showed an increase in knowledge scores, with the mean pretest score rising from 12.54 to 18.14 in the posttest, as well as an increase in attitude scores from a mean of 44.88 to 48.61. Conclusion: Statistical tests showed a significant difference between the scores before and after the intervention, both in knowledge (p = 0.000) and attitude (p = 0.000). These findings demonstrate that animated infographic video media has a positive effect on improving students' knowledge and attitudes regarding diarrhea prevention. Recommendation: This media can be used as an effective and engaging educational strategy to support health promotion programs in elementary schools.</p> Estu aulia Hendawati Maliha Amin Faiza Yuniati Esti Sri Ananingsih Copyright (c) 2025 Epidemiological Journal of Indonesia https://creativecommons.org/licenses/by-nc-sa/4.0 2025-10-31 2025-10-31 4 2 79 86
