Background of the Project
Jakarta is the preeminent urban center of Indonesia
. It is the main commercial hub of Indonesia. Regional urbanization
has contributed to making Jakarta one of the largest metropolitan areas in the world. The Special Capital District of Jakarta
(DKI Jakarta)1 covers an area of approximately 650 km
2with a population of about 9.6 million in 2010, while the population
of Greater Jakarta
2(covering about 7,300 km
2) stood at 27.9 million
2. Rapid growth and inadequate development of public
services have contributed to a host of problems the most severe of which are manifested in disastrous perennial flooding.
Flood management infrastructures in Jakarta
. Greater Jakarta is surrounded by several dormant volcanoes whose
slopes form the upstream catchment areas of the 13 major rivers that flow through Jakarta to the Java Sea. The rainy
season begins in late November and ends in early April. Jakarta sits in the lowest lying areas of the basin. Forty percent of
Jakarta lies below sea level, including most of North Jakarta, which is being severely threatened by acute land subsidence.
The basic principle of flood management in Jakarta is to divert peak flows from upstream areas around the core of the city,
directing flows to the East and West of Jakarta via two major flood canals emptying into Jakarta Bay. Within the city, the
macro drainage system consists of 13 rivers and a large number of drainage channels. The macro drainage system can be
divided into several subsystems that are separated by floodgates. In low-lying areas, there are polders, which are protective
systems that utilize retention reservoirs at the lowest point and regulate excess water levels by pumping out of the system.
Poor condition of the system, under-implementation of operations and maintenance (O&M), and inadequate local drainage
management result in rapidly occurring inundations during rainfall conditions.
Causes of flood in Jakarta
. The overall urbanization trends are central to the causes of Jakarta flooding. This has led to
the deterioration of several critical factors. The encroachment and/or development of critical catchment areas have resulted
in both increased rainwater runoff and lack of natural stormwater retention areas both within the city and in upstream areas
of the catchment. Increased generation and inadequate management of solid waste have contributed to waste choked
canals and floodways, exacerbated by insufficient maintenance resulting in weakening structures and sediment build-up.
Some canals are operating at less than a third of their original capacity. Land subsidence continues at increasingly alarming
rates, principally caused by intensive deep groundwater abstraction. Land subsidence results in increased vulnerability to
flooding due to the reduced gravitational capacity to channel storm flows to the sea and an increased risk of tidal flooding.
Flood management institutions in Jakarta
. Responsibility for the development and management of flood infrastructure in
Jakarta is shared between two central government agencies and the Provincial Government of DKI Jakarta (DKI) i.e. The
Balai Besar Wilayah Sungai Ciliwung - Cisadane (BBWSCC)3 under the Directorate General of Water Resource (DGWR) of
the Ministry of Public Works and Housing (MoPWH); the Directorate General of Human Settlements (DGCK) of the MoPWH;
and DKI, through its provincial public works office (DTA-DKI)4, is responsible for the remaining drains, floodways and
retention basins.
1.4
Project Objectives
The Project Development Objective (PDO) of the Jakarta Urgent Flood Mitigation Project/Jakarta Emergency Dredging
Initiative (JUFMP/JEDI) is to contribu
te to the improvement of the operation and maintenance of priority sections of Jakarta’s
flood management system. The PDO will be achieved through:
a)
Dredging sections of selected key floodways, canals and retention basins to improve their flow capacities, and
disposing the dredge material in proper facilities;
b)
Rehabilitating and constructing embankment in sections of, and repairing or replacing mechanical equipment in,
the same selected key floodways, canals and retention basins to sustain and improve their operations;
c)
Establishing institutional coordination between the three responsible agencies to encourage coordinated
development, and operations and maintenance (O&M) of Jakarta's flood management system, and
d)
Strengthening the capability of the responsible agencies to improve the operations, maintenance and
management of Jakarta's flood management system.
1 Jakarta is officially designated a province with special status as the capital of Indonesia i.e., DKI Jakarta (or ‘Special Capital City District of Jakarta’). 2 More than double the population of 11.9 million in 1980.

1.5
Construction Packages
The ultimate goal is to improve Jakarta’s flood management system and reduce the time and duration of floods by dredging
selected floodways, channels and retention basins and to dispose of the excavated (or dredged) materials at three managed
facilities each being many kilometers from the proposed construction sites. As discussed in other sections of this Inception
Report, there are 13 (thirteen) rivers flowing northwards through Jakarta. These form its macro drainage system. Overtime,
poor operation and maintenance (O&M) and ineffective solid waste management, has resulted in significant sediment
deposition and solid waste build up. Additionally, uncontrolled (intentional) upstream land development has resulted in both
increased surface runoff and lack of natural storm water retention areas due to the alteration of the surface (less forested
areas, more houses and roads, etc.). Effects of climate change has also changed the hydrology of the region resulting in
intense and longer duration downpours at times and shifting of the timing of wet and dry seasons.
This Project will focus on 11 (eleven) channels and 4 (four) retention basins which have been identified as priorities. The
major scope of works under the Project include the following: (i) dredging of floodways, channels, and retention basins and
disposing the excavated material at three separate disposal facilities; (ii) rehabilitating and constructing embankments and
repairing or replacing mechanical equipment on various structures, and (iii) constructing Sentiong pump station
One management concern with respect to this Project will be the development of effective coordination and cooperation of
three separate government authorities. Under Indonesian law, the Ministry of Public Works and Housing Affair (MoPWH),
[through two departments - DGHS and DGWR], and the provincial government of Jakarta, DKI are responsible for managing
different aspects of Jakarta's flood control system. The MoPWH departments are responsible for floodways that cross
provincial boundaries; while the Jakarta Public Works Department (DTA-DKI) is responsible for drains and retention basins
within its boundaries.
For this Project, these are the works that are under the three separate authorities:
Under MoPWH-DGHS: (i) Tanjungan drain, (ii) Lower Angke drain, and (iii) Cideng-Thamrin drain;
Under MoPWH-DGWR: (i) Cengkareng floodway, (ii) West Banjir canal/floodway, (iii) Lower Sunter floodway; (iv) Upper
Sunter floodway, and (v) Sentiong Pump Station;
Under DPU-DKI: (i) Ciliwung-Gunung Sahari floodway, (ii) Sentiong-Sunter drain (including Ancol canal), (iii)
Grogol-Sekretaris drain, (iv) Pakin-Kali Besar-Jelakeng drain, (v) Krukut-Cideng drain; and (vi) Krukut Lama drain;
and
Under DPU-DKI: (i) North Sunter retention basin, (ii) South Sunter retention basin, (iii) East Sunter III retention basin, and
(iv) Melati retention basin.

Volume of Works
Surveys of the selected key floodways, canals and retention basins carried out during project preparation estimated the total
volume of dredge material to be dredged to be about 3.4 million m
3(of which about 95,000 m
3are estimated to be solid
waste). About 42.2 km of embankments are expected to be rehabilitated or constructed within these floodways, canals and
retention basins. Details of the project achievement to this period summarized in Table 1.5 below.

practices during project preparation period. The sediment to be dredged consists mainly of soft soils (silt and clay), mixed
with garbage and various solid waste
6.
The dredging considers the removal of under-water obstacles, such as rubble and piles from old structures or old
embankments, especially under bridges. Also, trunks and branches of trees could be found in the water. All sediment from

under the bridges and other obstacles including sediment on the embankment will be removed as well. All dredging works
will be executed from the water, except some temporary disposal and the truck loading works.
All equipment used for the removal (excavation) of the sediment must be able to position themselves in the water during
dredging operations with spuds. This is to guarantee that each section of the drains, floodways and waduks are dredged.
Damage of embankments, obstacles or any other assets before, during and after the dredging works will be repaired.
1.5.4
Transportation Methods
All transport of sediment should avoid leakage or spills and dump trucks should be 100% watertight
7. Any leakage of the
dump trucks on the truck loading location and along the route to the disposal sites will be cleaned immediately. Each truck
movement, limited to 22.00 pm to 05.00 AM, will be registered. In particular, for disposal at Ancol CDF, this will include daily
reports mentioning type of truck, license plate number, time of truck departure from the loading location, and time of arrival at
the deposit area in Ancol CDF.

2.4.1
Quality Assurance/Quality Control
Quality Control / Quality Assurance Engineer carried out monitoring and evaluating the method of works and work progress
of contractor related to its plan and target for each month to keep the project activities in due diligence of the contract. The
sequence of construction activities and method of works by contractor was concerned from QA/QC point of view. In
particular, dredging and rehabilitation of the existing slope protection at Upper Sunter floodway were planned at the same
location.
From QA/QC point of view, implementation of package 6 is in line with the contractor Quality Plan provided in the beginning
of contract commencement. A set of procedures and communication between supervision consultant and contractor as well
as with engineer has been established well. Regular meeting such as weekly and monthly meeting has been arranged at
fi
eld contractor’s office (weekly meeting) and at the
PIU office (BBWS Cilicis).
West Banjir Canal:
Execution of dredging and rehabilitation of slope protection and embankment (CCSP) run well. However, the daily dredging
progress was slower than the contractor plan.
Meanwhile, the physical progress of contract slightly behind the schedule. Capacity of logistic deployed by contractor in
West Bank Canal zone which consisted of float excavators and dump trucks was less than that calculated in pre-construction
analysis.
Korea Engineering Consultants Corp. in joint venture with PT. Puser Bumi Mekon, 20 in associated with PT. Tetira International Consultants, PT. Duta Cipta Mandiri Engineering Consultant
works performed by contractor were not fully supported by other facilities such as temporary disposal and traffic
management of disposal transportation from site to CDF Ancol.
To solve this problem, the consultant has instructed the contractor to prepare a new working plan increasing its capacity by
mobilize more equipment and temporary disposal area in order to allow more trucks and loader to bring disposal to CDF
Ancol.
Upper Sunter Floodway:
Rehabilitation of slope protection at Upper Sunter floodway exceeded original contract volume. Unexpected land sliding at
several places changed the type of construction design and volume of works in respect to local resident beneficiary.
Consultant advised contractor to improve their equipment capacity and working method to catch up the remaining contract
period.
Dredging was referred to the shop drawing proposed by contractor and have been approved by the engineer. However, the
dredging to a certain limit caused degradation of bed level of canal, in consequence destabilized existing aged, deteriorated
slope protection work. In some places, existing concrete blocks and retaining wall were fallen down after dredging works in
the place finished.
QA/QC insisted contractor to avoid any dredging activity until rehabilitation of slope protection work is completed. The
contractor was advised to propose detailed design and shop drawing for rehabilitation of slope protection work. Technical
advisory has been given to the contractor to construct concrete pile to increase stability of the slope.
Issues Recommendation Actions/Impacts
The contractor advised to propose detailed design and shop drawing for rehabilitation of slope protection work. Technical advisory has been given to the contractor to construct concrete pile in order to increase stability of the slope.
Sliding of existing concrete blocks and retaining wall occurred after dredging in the place finished.
Contractor, consultant and engineer agreed to inventory actual condition slope protection both sides of the canal and prepare amendment to the contract based on new slope protection plan.
Contractor agreed to start rehabilitation as soon as possible to avoid further collapse of existing slope protection.
Consultant has strongly recommended to prepare a new working plan and mobilize more equipment and temporary disposal area.
In some days, daily dredged volume reached to about 4,000 m3 which is near the target plan

Tensile strength test and strand test at Puspitek Serpong as independent laboratory
Placement stockpile of CCSP
Reference with technical specification of material produced by supplier was checked in independent laboratory before approval to be procured. QA/QC witnessed the test accordingly. Strength of CCSP with its technical specification was shown in laboratory report.
Broken CCSP stockpiled on unflatten ground should be removed from the site.
Contractor removed the broken CCSP from site and prepare a flat surface ground for placement of stockpile on field.
Project coordination meeting on monitoring and evaluation of the project implementation was chaired by CPIU. Sentiong Pump preparation was discussed in the meetings.
Consultant is preparing document of tender and design drawing.
Sliding of existing slope protection at Upper Sunter floodway occurred at number of places.
The existing slope protection works built more than 20 years ago are aged, deteriorated, unstable and foundation eroded in some parts of the construction. Even more, heavy loads of many houses along both sides of canal as well as traffic using the both side inspection road weekened the embankment. Dredging and construction activities might contribute to the stability of the slope protection.
Quick action to prevent more sliding must be taken by contractor. Technical advices has been provided for design of protection.
Contractor started to construct mini piles and slope protection at the places where damage was severe.
Float excavators were used for dredging and at least two or three times move to reach to temporary disposal.
Contractor was advised to improve working method of works as well as number of equipment.
Korea Engineering Consultants Corp. in joint venture with PT. Puser Bumi Mekon, 22 in associated with PT. Tetira International Consultants, PT. Duta Cipta Mandiri Engineering Consultant
Documentation and record of data must be managed properly in order to avoid any dispute in future.
Control survey of dredging works which is extremely important: QA advised to the Survey Team to keep survey book and data, calculation results and drawing to be signed by all parties, to be known by field supervise and head office.
Field supervisors and survey team were reminded to follow the standard operation procedures as mentioned in Quality Control Plan prepared by the consultant.
Volume of dredging is an object of auditing by BPK. The computation must be supported with valid evidence and survey data.
Cross monitoring/joint survey on dredging was advised by CPIU every two weeks or once a month.
Surveyor used total station in surveying the dredge volume.
CPIU advised contractor and consultant to check the dredging works regularly in order to avoid discrepancy of volume at site and at CDF Ancol.
Kali Adem is unlikely to be dredged due to social problems not exposed in LARAP document.
A joint site visit by all related agencies was advised to examine the Kali Adem actual condition. It is expected that team will decide whether dredging of Kali Adem to be continued or not.
The consultant, contractor and PIU conducted site inspection to evaluate technical, social and environment impacts of dredging at Kali Adem.
The remaining time of 181 calendar days may not sufficient to complete remaining construction work.
The contractor was requested to prepare a revised action plan with improvement of method of works, number of equipment, trucks and its facilities etc.

Canal slope sliding at Upper Sunter floodway was not expected when design was prepared. Factual condition of existing
slope protection in some places is not shown because sediment covers it. Dimension of designed canal was smaller than
dimension of existing canal. That means dredging of sediment are not up to the original cross section of the canal. When
dredging reach to the designed profile, remain sediment was fallen and disturbed stability of existing slope protection.
Consequently, some were cracked and even broken down in to the canal.
There are some factors contribute to the existing slope protection at Upper Sunter canal. It was found at some places
sewerage from houses poured into canal without proper drain outlet caused scoring at the toe of slope weakening stability of
canal slope and slope protection work. Seepage may occur under inspection road caused softening soil material of
embankment and decreased its bearing capacity. As the inspection road is used also as communal road, vehicles beyond
capacity of the road also contributed to cracking of concrete pavement of the inspection road.
Issues Recommendation Actions/Impacts
Driving mini piles to stabilize slope or existing retaining wall were done manually using simple tripod and hammer seems not to reach hard ground.
Contractros was instructed to drive mini pile reach up to 2.5 m at least.
It requested the contractor to use a proper hammer to push mini piles up to design level.
Mini piles were driven as instructed.
Soil of embankment of the drain is soft and unstable.
Instructed the contractror not to leave mini piles uncompletely driven.
Contractor has used proper equipment to drive mini pile to design elevation.
The Mini Pile that was not properly driven using excavator.
Instructed to use a proper hammer in driving of mini piles.

Other canal slope sidings occurred at STA 11+350 until STA 11+425 at the right side. Slid material was sediment and garbage.
Canal embankment was composed with sediment and garbage dumped along canal side and communal access road with concrete pavement was constructed above the unstable embankment.
When the canal is dredged the stability of the embankment slope weakened and the paved road cracked and slid.
It was instructed to stop dredging until the canal slope is protected with mini pile and stabilized.
Dredging was stopped as instructed.

Monitoring of the impacts of flood to the project: The floods in rainy season in Jakarta hampered construction works as well
as disrupted the stability of the river slopes, especially at Upper Sunter floodway. Soil erosion from the banks at Sodong
area, STA 13+125, STA 14+600 and other locations increased the sediment volume in the floodway, causing increase of
turbidity, total suspended solid (TSS) and sediment quality (TCLP) of river water. However, in terms of environmental quality,
water quality over the threshold quality standard set by the Government of the Republic of Indonesia was not found.
Canal slope sliding occurred and can occur again if the slope is not strengthened. So that, various factors that can affect to
slope sliding should be considered in the design for the slope strengthening. The impact of flood in the rainy season such as
rising of river water to an extreme level could not be prevented at present field condition.
Analytical review on the constraints in project implementation at Muara Angke: Various constraints need to be assessed
prior to project implementation. Especially, constraints in compliance to the environmental regulations in addition to technical
and social constraints in dredging around the protected forest at the left side of Muara Angke downstream should be
carefully assessed. It is estimated that dredging at site could cause damage to protected forests and wildlife migration and to
residential areas. The mangrove forest that has been managed by the mangrove forest conservation community located
should not destructed by the dredging work at Muara Angke downstream.
Monitoring of sampling for RKL/RPL quarterly report (October 2017 - December 2017): PT. PP Tbk. has conducted sampling
of Water and Air and TCLP was done by an accredited laboratory i.e. PT. Sucofindo (Persero). Implementation of these
samplings and preparation of RKL / RPL quarterly report were reviewed and guided. As a reference, supervision consultant
with PT. Unilab Perdana has also conducted the same environmental inspection on December 26-27, 2017.
The watersheds of Upper Sunter Floodway and West Banjir Canal generally has been contaminated by organic compound
pollutants in the range from medium contaminated to heavily contaminated. Anaerobic fermentation process happened
along the river flow and raised the precipitation of fermentation mix to the sediment erosion from the upstream. The fineness
of precipitation from these fermentations influenced the overall river sediment structure.
