JAKARTA, KOMPAS — The National Capital Integrated Coastal Development (NCICD) project, which is currently integrated with the reclamation project of 17 islands on Jakarta Bay, was created to provide solutions for a number of problems in the capital city, including land subsidence and flash floods. However, until now, some of these problems have only been handled partially.
This was one of the major points of the discussion held by Kompas in Jakarta on Friday (16/9/2016). Attending the discussion were Bandung Institute of Technology (ITB) applied geology research group head Lambok Hutasoit, Bogor Agricultural Institute (IPB) fisheries and maritime sciences faculty strategic research coordinator Alan Koropitan, Indonesia Water Institute executive director Firdaus Ali, ITB center for environmental studies researcher Hesti D Nawangsidi and Maritime Affairs and Fisheries Ministry marine and coastal data laboratory head Widodo Pranowo.
One highlight in the discussion was the construction of Phase A of the sea wall, which was the first of NCICD’s three phases. Alan Koropitan said that the construction project should be prioritized. According to Alan, the construction of the project and the implementation of sanitation and wastewater management systems can provide solutions for a number of problems in Jakarta, including land subsidence, flash floods and pollution and sedimentation in Jakarta Bay.
In the field, the reclamation islands’ construction is prioritized in Jakarta Bay, whereas Alan and Widodo said that the man-made islands would obstruct the flushing process of a number of potentially damaging chemical substances, including nitrogen, phosphate and DEET (diethyltoluamide).
Firdaus Ali agreed with the importance of the Phase A construction of the sea wall. However, he said that the construction project needed a huge amount of money. This is why private sector contribution in the form of social responsibility projects by the developers holding reclamation licenses is necessary.
Hesti D Nawangsidi, who has advised the Jakarta administration in the reclamation process since 1995, said that the total length of the Phase A sea wall was 120 kilometers, stretching from Tangerang in Banten to Bekasi in West Java. In Jakarta waters, the sea wall would be 98 kilometers long. “The financing is split between the Jakarta administration, the central government and private entities. Currently, the progress is partial,” she said.
Kompas reports show that 25 percent of the project is constructed by the central government through the Ciliwung-Cisadane Flood Control Office (BBWSCC), another 25 percent by the Jakarta administration and the remaining 50 percent by private companies. This share of responsibilities has been detailed clearly (Kompas, 8/6/2016).
