Abstract

Hookworm infection remains an important community health concern, particularly in the coastal areas of East Kalimantan, Indonesia, where environmental conditions facilitate transmission. Key risk factors in this region include the presence of domestic animals (cats and dogs), infection in these pets, and specific types of soil surrounding households. This study aimed to determine the prevalence of hookworm infection and its association with various environmental and behavioral risk factors. A cross-sectional survey was conducted in 2019 among 213 individuals from rural areas of Kutai Kartanegara Regency. Stool specimens were examined using Kato-Katz and Koga Agar Plate (KAP) culture technique. The prevalence of hookworm infection was 33.8% (72/213). Higher infection rates were significantly associated with older age (≥13 years), agricultural occupation, poor sanitation facilities, use of unsanitary water sources, and open defecation practices. Environmental factors, including wet soil, high soil organic carbon content, low elevation, high humidity, frequent rainfall, and proximity to rivers or plantation areas, were also significantly associated with hookworm infection (p < 0.05; ORs ranged approximately from 1.7 to 2.9). The presence of hookworm-infected domestic dogs was significantly associated with human infection (p < 0.001). These findings highlight that hookworm transmission in coastal East Kalimantan is influenced by an alliance of environmental, behavioral, and animal-related factors. Comprehensive control strategies focusing on sanitation improvement, environmental management, and control of zoonotic reservoirs are essential to reduce infection rates in endemic rural setting.

Abstract

Background : Diarrhea remains a global public health problem with high morbidity and mortality rates. Environmental conditions such as poor sanitation infrastructure and hygiene practices have the potential to increase the risk of diarrhea. Objective : This study aims to analyze the relationship between environmental factors and the incidence of diarrhea in East Kalimantan Province based on big data from the 2023 Indonesian Health Survey (SKI). Research Methods/ Implementation Methods : This study employed a cross-sectional design using secondary data from 15,854 SKI respondents. Variables included gender, education, drinking water sources, water quality and treatment, storage containers, wastewater disposal, waste management, sanitation access, and hygiene practices. Data were analyzed using Chi-square and logistic regression to determine independent environmental factors influencing diarrhea incidence. Results : The prevalence of diarrhea was 2.1%. Bivariate analysis showed a significant association between the incidence of diarrhea and education (p=0.001), drinking water source (p=0.003), physical quality of drinking water (p=0.000), raw water source (p=0.012), waste management (p=0.002), and sanitation hygiene (p=0.000). In the models of multivariable logistic regression analysis, it was found that physical quality of drinking water (AOR=2.058; p<0.001), level of education (AOR=2.008; p<0.001), and waste management (AOR=1.276; p=0.032) were the main determinants of diarrhea incidence. Conclusion/Lesson Learned : Poor drinking water quality, low levels of education, and inadequate waste management increase the risk of diarrhea in East Kalimantan. Efforts to improve water quality, environmental health education, and household-based waste management need to be strengthened to reduce the incidence of diarrhea.

Abstract

Small islands often face challenges in providing clean water, including the poor quality of dug wells on Barrang Caddi Island. This study aims to evaluate the effectiveness of coagulation using moringa seeds and filtration using pumice and mangrove charcoal in reducing turbidity and improving water quality. The study design is a quasi-experimental study using a one-group pretest-posttest approach. Samples were purposively selected from one dug well with the highest TDS value that is actively used. The treatment was conducted in three replicates to ensure consistency and reliability of the results. The coagulation process used Moringa oleifera at a dose of 350 mg/l, while filtration used pumice and activated charcoal media with a thickness of 60 cm. Effectiveness was calculated based on the difference in turbidity levels before and after treatment and analyzed using the Kruskal-Wallis test and post hoc analysis. The results showed significant differences in all methods applied (p = 0.016). Moringa seed coagulation reduced turbidity by 26.85%, pumice filtration by 68.72%, activated carbon filtration by 79.96%, and the coagulation-filtration combination by 74.80%. Activated carbon filtration demonstrated the highest adsorption capacity. This study concluded that the combination of coagulation and filtration is a practical and applicable solution for addressing clean water issues in coastal and island regions.
