2024-09-20T07:04:11+00:00

Workplace noise is one of the physical factors that is often overlooked, although long-term exposure can have serious impacts on cardiovascular health. In workers exposed to noise, blood pressure and heart rate often increase as the body's response to physical stress. This physiological mechanism triggered by prolonged noise can result in an increased risk of cardiovascular disorders, including hypertension and heart rhythm disorders. The purpose of this study was to analyze the effect of noise on increasing blood pressure and heart rate in workers in the workshop area, especially the dynotest room. This type of research is observational with a cross-sectional research design. Conducted in December - May 2024 with the object of research on workers exposed to noise in the workshop area, especially the dynotest room. Data were analyzed using the Logistic Regression test. The total sample was 40 workers in the workshop area and dynotest room. Data were collected from observations, room noise measurements, blood pressure, and heart rate. Based on the results of the study, the average results for the dynotest area were 83.5 dBA, while for the dynotest room, the average results were 117.8 dBA. The results of statistical tests of blood pressure and pulse rate in workers obtained a sig value = 0.001. These results indicate an increase in blood pressure and pulse rate due to noise. It is recommended for the Company to monitor workers to find out the disorders caused by noise.

2024-10-22T03:01:22+00:00

Stunting is a nutritional problem that remains high in Indonesia, especially in rural areas like Bondowoso. Poor basic sanitation and bad implementation of Clean and Healthy Living Behavior are often associated with stunting in children under five. This study aims to analyze the relationship between basic sanitation factors and Clean and Healthy Living Behavior as a determinant of stunting in the working area of Sempol Community Health Center in 2024. This research used a case-control study methodology in conjunction with observational analytics. The samples were houses with stunting and non-stunting toddlers in the working area of Sempol Community Health Center. The samples are 24 for each group, using a systematic random sampling technique from a population of 925 toddlers. Data analysis using the Chi-square test with 0.05 degree of error. The result of this research showed that there are differences in basic sanitation facilities of houses and Clean and Healthy Living Behavior in stunting and non-stunting toddlers in the working area of Sempol Community Health Center in 2024. Basic sanitation and Clean and Healthy Living Behavior factors are important factors in efforts to prevent stunting. Improving access to sanitation and promoting the Clean and Healthy Living Behavior program must be a priority in the Public Health Intervention Program in Bondowoso.

Analysis of the Relationship between Residential Environmental Sanitation and the Risk of Dengue Fever (DHF) Incidence in the Moropelang Health Centre Working Area, Lamonga, East Java

2024-09-20T07:13:21+00:00

Dengue fever (DHF) is a significant health problem in tropical regions, including the working area of Puskesmas Moropelang, Lamongan. Data shows that DHF cases continue to be found in the period 2020-2023. This study aims to analyse the relationship between residential environmental sanitation and the incidence of DHF in the region in 2024. This study used a quantitative approach with an analytical observational design based on the case-control method. The study population was 148, with a total sample size of 74 cases and 74 controls. Independent variables included environmental conditions, water reservoirs, and larval density, while the dependent variable was dengue incidence. Data were analysed using the Chi-Square test. The results showed a significant association between environmental conditions (p=0.013), water storage conditions (p=0.003), and the number of free larvae (p=0.004) with the incidence of DHF. Respondents with poor home environmental conditions had a 2.3 times higher risk of DHF, while the risk increased to 2.7 times in poor water reservoirs, and 2.6 times in environments with high larval density. This study concluded that residential environmental sanitation plays an important role in the prevention of DHF. Weekly mosquito nest eradication efforts, community education, and regular monitoring of larvae are recommended to reduce the incidence of DHF and improve environmental health.

Risk Factors of Home Sanitation on the Incidence of Stunting in the Working Area of Tetewatu Health Centre, North Konawe (2024)

2025-05-11T09:06:27+00:00

Stunting remains a major public health issue in Indonesia, influenced by multifactorial determinants including environmental sanitation. Poor household sanitation increases the risk of repeated infections and nutrient malabsorption, contributing significantly to impaired growth among children under five. This study aims to analyze the association between household environmental sanitation factors and the incidence of stunting in children under five in the Tetewatu Health Centre area, North Konawe District. A case-control study was conducted from January to March 2024, involving 54 respondents (27 stunted cases and 27 matched controls). Data were collected through structured interviews, direct observations, and anthropometric measurements. Variables assessed included ownership of clean water sources, healthy latrines, handwashing with soap (HWWS) practices, and household food management. Data were analyzed using Chi-Square and Fisher’s Exact tests, with significance set at p<0.05. The results showed significant associations between all environmental sanitation variables and stunting. Households with poor access to clean water (OR=10.95; p=0.024), lack of healthy latrines (OR=10.95; p=0.024), poor HWWS behavior (OR=7.35; p=0.019), and inadequate food management (OR=29.69; p<0.001) had a significantly higher risk of stunting. Food management emerged as the strongest predictor. Conclusion: Environmental sanitation factors, particularly food hygiene, access to clean water, sanitation facilities, and handwashing practices, play a critical role in preventing stunting. Interventions targeting household sanitation and hygiene behaviors are essential to achieve sustainable reductions in child stunting rates. Strengthening the WASH (Water, Sanitation, and Hygiene) component in stunting prevention programs is urgently recommended.

Spatial Analysis of Environmental Determinants of Dengue Hemorrhagic Fever (DHF) Endemic Areas in the Working Area of Puskesmas Purwokerto Selatan, Banyumas Regency, 2022-2023

2025-05-11T08:26:35+00:00

Dengue Hemorrhagic Fever (DHF) remains a significant public health issue in Indonesia, particularly in endemic areas such as South Purwokerto. Despite a reported 61% decline in cases from 2022 to 2023, transmission persists, indicating the need for a deeper understanding of environmental determinants. This study aims to conduct a spatial analysis of environmental factors associated with dengue case distribution in the working area of the South Purwokerto Health Center during 2022–2023. This research employed an observational design with a qualitative exploratory approach. Data were collected from both primary and secondary sources, including direct measurements of indoor temperature and humidity, health center reports on larval-free index (LFI), larval density, rainfall, and case distribution. Geographic Information Systems (GIS) using ArcGIS software were utilized to analyze spatial patterns of dengue transmission. The findings showed that the average indoor temperature in patients’ homes was 31°C and relative humidity was 70%, conditions that support mosquito breeding. In 2022, the pattern of dengue cases inversely correlated with rainfall, while in 2023 the pattern was inconsistent. The dominant transmission pattern was “separated” (>100 m radius) with 55% of cases in 2022 and 60% in 2023 falling into this category. Only one sub-district, Teluk, failed to meet the Larval-Free Index threshold in 2022, while all areas improved in 2023. In conclusion, although environmental indicators improved in 2023, the persistence of cases indicates hidden transmission risks. Targeted vector control interventions and increased community participation are essential for sustainable dengue prevention.
