Muara Angke Fisheries Settlement Area, North Jakarta is a region that potential to experience water scarcity caused by limited water piped network and accompanied by poor groundwater quality due to seawater intrusion. In this situation, rainwater can be an alternative water source to meet household water needs. However, the implementation of Rainwater Harvesting (RWH) in hamlets 22, Muara Angke has not been a priority. Hence, this study aims to assess the acceptance of residents on RWH, their willingness to participate in implementing RWH, and the challenges of installing and maintaining RWH. The study uses the Multi-Dimensional Scaling (MDS) method with social, economic, and environmental aspects. The social aspect consists of 3 indicators: social capital, education, and government support. The economic aspect consists of 3 indicators: income, maintenance cost, and saving. The environmental aspect consists of 3 indicators: the quality, the quantity, and the continuity of rainwater. Data collection in this study involved 93 questionnaires which distributed after socialization of the RWH program and its benefit to the residents. This study analyzes the local people acceptance after socialization the RWH program and benefit to the residents. Results showed that education, social capital, government support, income, maintenance costs, saving, and 3 aspects of rainwater were statistically significant in explaining local resident acceptance of RWH in the study area. The people acceptance of RWH after socialization was change compared to before the socialization.

Urban development is currently one of the main focuses of sustainable development, especially in SDGs point number 11. Coastal areas are potential areas for growth, both from an environmental, social, and economic perspective. However, this area is vulnerable to the threat of natural disasters, which impact communities’ vulnerability, especially for their settlements. The coastal area settlements’ condition still uses conventional materials, which tend to be not environmentally friendly. The research focuses on identifying and analysing fishery village areas, particularly human settlements and environmental problems. So that at the end of the study, we can find problems that hinder sustainable development and are useful as a database for the development of sustainable settlement designs in the future. The method used is mixed between quantitative and qualitative, with direct observation and secondary data analysis and considering several aspects such as socio-economic aspects, the environment as a whole, and physical elements of the building (material, architectural elements, zoning). The results showed that the area’s existing design is directly proportional to the socio-economic level of the community and its socio-culture, as well as a problem point in the development of sustainable coastal settlements.
