Opportunities and Challenges Application of Desalination Technology for the Clean Water Availability in Bangka Islands

Abstract

Abstract Bangka Belitung islands is a province with limited clean water due to a lot of tins mine which is not environmentally friendly. on the other hand, Bangka Belitung has a 1200 km coastline more easily to access seawater. for this reason, the desalination technique is used as a way to overcome the limitations of freshwater. In addition to answering the needs for clean water, desalination techniques can also answer the need for salt on the island of Bangka by utilizing brine as waste from the processing of desalination techniques. this study applies the interpretive structural modeling (ISM) method which is based on several criteria such as social, economic, and environmental considerations in assessing the opportunities and constraints of implementing seawater desalination techniques. Result shows of the hierarchical analysis, the main challenges in desalination technique are high operational costs, distribution, and access to water resources and a regulatory framework that has not yet been established. the main opportunities in the desalination development are raw materials (seawater) are easy to access, environmentally friendly technology and support from local government.
