The Indonesian archipelago (archipelago) has small islands. Small islands have a wide range of vulnerabilities due
to its small size, both physically and socio-economic. In addition, the utilization of natural resources that are prone to bring
greater conflict between economic development and environmental consequences. Priority environment is very important for
small islands and coastal areas alone, which includes the balance of population and resources there are very important in
the future will come. Given the standpoint of environmental health risks that have the potential for significant risk to human
health and sanitation among other relevant indicator berish and drinking water sources, and ekscreta wastewater, solid
waste, unhealthy behaviors, it is necessary to study on the risk index of sanitation in the islands Napier and Sinjai through
approach Confirmatory Factor Analysis (CFA). The results showed that the risk of sanitation is fit model based on criteria
CMIN / DF and RMSEA. The highest risk index sanitation is on some islands, namely Samolona, Barrang Lompo, Bird Loe,
Kodingareng, Kambuno and Lumu-Lumu. So there needs to be the socialization of latrine ownership, ownership SPAL, use
of clean and drinking water sources are not protected, the scarcity of clean water and drinking, physical quality of water does
not qualify and the distance to the water source pollutant source ≤ 10 meter
