Clean water supply vulnerability model for improving the quality of public health (environmental health perspective): A case in Spermonde islands, Makassar Indonesia

ABSTRACT

Objective: This study aims to generate a clean water vulnerability model based on exogenous variables: accessibility, socio-economic, and population behavior to endogenous variables: occupancy density and water vulnerability to support the quality of public health in Spermonde island. Methods: This research was conducted in three islands (Spermonde), namely Lae-Lae, Barang Caddi, and Lumu-Lumu. The research design is observational analytic with a cross-sectional approach. The 212 respondents were obtained using a simple random sampling method. A questionnaire was employed to interview respondents related to the level of environmental vulnerability. Data were analyzed using structural equation modeling (SEM). Results: The study found some variables are not statistically significant associated with water vulnerability such as accessibility to occupancy density (P = 0.095), socio-economic to occupancy density (P = 0.991), accessibility to water vulnerability (P = 0.383), socio-economic against water vulnerability (P = 0.417), occupancy density for water vulnerability (P < 0.01). In contrast, behavior to occupancy density (P = 0.002), behavior towards water vulnerability (P = below 0.01) have a significant association. Conclusion: Community behavior and occupancy density are the main factors associated with the vulnerability of clean water on the small spermonde islands. Adaptation behavior with water vulnerability such as water storage and saving needs to be improved. (AU)
