Abstract

The potential for surface marine water pollution from domestic greywater wastewater poses a threat to small, densely populated islands. This condition will affect the sustainability of the ecosystem in the surrounding environment. This research was conducted on Bungin Island, located in Sumbawa Regency, Indonesia. The island is one of the most densely populated islands with an area of only 8.5 ha and a population of 3,400 people. This research aims to map the potential sustainability of the application of Integrated Household Constructed Wetlands (IHCWS) on Bungin Island, Indonesia as an alternative to managing greywater from household activities. There are six dimensions and thirty sustainability attributes studied including ecology, socio-culture, economy, technology, policy, and public health. The data obtained were analyzed using the RAPFISH MDS method. The results showed that the potential application of IHCWS on Bungin Island in each aspect, ecology (88.68%), socio-culture (79.13%), economy (99.66%), technology (99.71%), policy (99.71%), and public health (88.68%). In conclusion, the IHCWS is classified as sustainable. The application of technology that requires maintenance is not by the conditions of small island communities. This is one of the sustainable solutions to mitigate environmental pollution, especially marine in small islands that have a high population density.
