Abstract
This paper discusses efforts in building the sustainability of coastal cities against the water crisis, with the study area in Cilegon, Banten Province. The study results in several studies that estimate that Cilegon will experience a water crisis in 2025. This is a challenge, especially in the effort to fulfill the sixth global target of Sustainable Development Goals, namely to fulfilling 100% clean water needs by 2030. To answer the research question, this study uses a system dynamic method by observing the simulations of relations between variables to be able to balance the gap between clean water needs and the availability of clean water in Cilegon. This study found that to balance this gap, Cilegon had to make technical engineering efforts to increase water availability and make a social engineering effort by reducing their needs for water. So the balance between the need and the availability of water will be achieved in 2030 in accordance with the SDGs target. This study recommends that in order to achieve the sustainability of a coastal city with clean water, a systematic effort is needed by managing the balance between the needs and availability of water in the coastal city.
Highlights
Sustainable Development Goals (SDGs) is a global action plan agreed by world leaders, including Indonesia, to end poverty, reduce inequality, and protect the environment[1]
The simulation results even estimate that the clean water crisis in the City of Cilegon occurred three years earlier than expected, namely in 2022
It can be concluded that the water crisis in 2027 did not happen, and achieving 100% access to clean water for the Cilegon City community can be fulfilled while maintaining the Cilegon City Industrial Growth Rate
Summary
Sustainable Development Goals (SDGs) is a global action plan agreed by world leaders, including Indonesia, to end poverty, reduce inequality, and protect the environment[1]. The SDGs consist of 17 Goals and 169 Targets that are expected to be achieved by 2030. Based on the 2018 National Socio-Economic Survey, the condition of fulfilling access to drinking water in Indonesia is currently only around 61.29%[3]. This figure is certainly still far from the target of achieving 100% access to safe drinking water nationally in 2030, as a commitment to realize the principle of No One Left Behind[4].
