• DHI engaged by KLH & DANIDA
• Study Objectives:
– Review and provide quality assurance of available data and previous assessments for Jakarta Bay
– Undertake a Rapid Environmental Assessment (REA), based on available data from previous studies and international experience
– Develop Criteria for detailed EIA of Reclamation works and Coastal Development in Jakarta Bay, based on international best practice
• Study Deliverables:
– Data Report (compilation and assessment of validity of available data/studies)
– REA Report
– Proposed Criteria for detailed EIA of future reclamation works and coastal development in Jakarta Bay

• Preliminary observations:
– The design is suitable from a hydraulic / navigation perspective
– Optimisation of the channel is required to ensure flushing is
maintained.
Tg. Priok Port
• Preliminary observations/issues:
– The design is suitable from a hydraulic / navigation
perspective.
– Optimisation of the channel is required to ensure flushing is
maintained.
– Construction impacts should be controlled through
Environmental Monitoring and Management Programme.
– Issues to be investigated:
• Release of contaminated sediments.
• Sedimentation affecting existing wharves and jetties

• Preliminary observations/issues:
– Desalination plant in centre which was constructed after the
Regional AMDAL was carried out. Impacts will need to be
assessed in detail.
– Proposed water features may need optimisation.
– Channel width optimisation to ensure
• Flood mitigation
• Maintain water quality in the channels.
– (detailed information on water level impacts in the channel is
not available in the Regional AMDAL).
– Land use planning/ buffer zones need to be considered with
respect to location near the Tg. Priok Port.

• Preliminary observations/issues:– Zoning concern with respect to residential and commercial
developments adjacent to industrial land uses (adequate buffer zone
needs to be taken into account, based on risk and emissions
assessment.
– Thermal efficiency in the existing powerplant area needs to be
assessed in detail (only one of the Power plants was assessed in
Regional Amdal).

• DHI’s preliminary conclusions:– Zoning concern with respect to residential and commercial
developments adjacent to industrial land uses (adequate buffer zone
needs to be taken into account, based on risk and emissions
assessment.
– Thermal efficiency in the existing powerplant area needs to be
assessed in detail (only one of the Power plants was assessed in

– Avoid infrastructure corridors where possible.

• Preliminary observations/ issues:– Channel widths – distance from shore needs to be optimised with
respect to flooding, water quality issues and impacts on aquaculture
and mangrove (inconsistent results on water level predictions in
AMDAL)
West Zone
– Potential for extending
mangrove area at
Muara Angke, potential
benefits on water
quality.
• Preliminary observations (cont’d):– New shoreline alignment protrudes from remaining areas - needs to
be reconsidered.

• Zoning Regulations (PerpresNo.54/2008)– Does not differentiate between
residential, industrial and commercial
– Zoning plan with separation of activities is required (buffer zones)
• Borrow sites need to be addressed
• Dredging impacts:– Sediment plume impacts
– Release of contaminated sediments
• Environmental management should be in line with international best practice for dredging and reclamation
