I. General Description Activity: JEDI Project Phase I includes: 1) Cengkareng Drain Flood Canal, 2) CiliwungGunung Sahari Drain, 3) Sentiong-Sunter Drain, 4) Sunter Flood Canal, and 5) Melati Detention Basin. II. Suggestions, Inputs, and Evaluations from Technical Team and EIA Evaluation Team, Jakarta Capital Region Provincial Environmental Impact Assessment Evaluation Commission 1. Meeting Chair a. The public should proactively provide information if environmental management is not carried out by the proponent for the JEDI Project river dredging. 2. Drs. Ramdhani a) Will there be an effort to empower the local residents by including them in the dredging activities? b) How will the post operational management be carried out, is there a Guiding Conceptual Framework for this? c) Technical Methodology in the EIA Document page III-58, Tables 3.24 and 3.25, need to be examined within Resource Formulation, because the community needs to be involved. d) Environmental Management and Monitoring Plans, page III-20, the need to have Resident-Observers/Inspectors, this needs to be organized so that it is clear in
the documents and the application of it must be accessible to the residents. Within the EIA document there are lines of control, but where are the functional lines? e) Basic duties and functions of the Community Relations organization need to be established. 3. Dr. Supardio a) Processes in the operational stage are extremely important, in connection with the Standard Operating Procedures of the activities. b) Specific information is needed on the activities with creation of dredging SOPs. c) The Disposal Area is extremely important; ensure that continued impacts don’t arise. d) Attention must be paid to sanitation issues. e) Implementation of the Environmental Management and Monitoring Plans must be carried out consistently, for example the cleaning of sediments must be carried out routinely. f) Post-operational management. g) A complaints coordination post is needed. 4. Drs. Ridwan Panjaitan, MSci a) Activity components should be explained clearly (area, width, volume of sediment) for individual sites. There needs to be a clarification on temporary dumping sites. b) Ensure there is a Center for Community Complaints established for each site. If there are problems, one must go to whom? c) Page III-3 shows impacts, but their management is not clear. Where is the matrix of responsibility for impacts? d) Environmental Management and Monitoring need to be more technically operational, for example for the temporary dumping sites, transportation, turbidity, etc. e) The organization for implementing environmental management in the construction and operational stages must be clarified among the Directorate General of Human Settlements, Jakarta Public Works, and the Contractor. This needs to be clearly assigned and calibrated within the Organizational Structure. Who is responsible for environmental management? f) Scope of responsibilities for management/monitoring is where? Does it reach to Ancol? The Environmental Management and Monitoring Plans need to be carried out consistently. g) Environmental Management and Monitoring needs to be specific (see items 3, 5, and 7 in the Matrix) with respect to traffic, air quality, and sanitation. Don’t generalize it, it is important to be specific. h) Community input should become part of the research study, and of the environmental management/monitoring.
5. North Rawa Badak Neighborhood Council a) Next to Rawa Badak Detention Basin, there is vacant land, which could benefit from sediment placement. b) When will Kapuk and Rawa Badak be dredged?
6. Abdul Rohim (Kartini Neighborhood Council) a) Please carry out real coordination and socialization. b) When will the operational stage socialization be carried out? c) Starting when will recruitment be carried out? 7. Simanjutak (Kapuk Neighborhood Council) a) How about if there is a community inspection/oversight mechanism, encompassing the block, street, neighborhood, and civil society? This needs to be clarified and the mechanism formed. What about an MOU? b) The organization responsible for environmental management (Directing Body), should be on standby at the project sites. 8. Drs. Ardian Prahara a) Manage spills of soil, so that they don’t disturb traffic and [cause] accidents b) Who will be responsible if accidents are a consequence of dredging impacts? c) To accommodate leachate in Ancol, please coordinate with the management of Ancol. 10.(sic) Drs. Irianto a) Please be really careful in implementation, particularly in establishing a complaints/grievance mechanism, will this be implemented or not? b) During dredging and transport, please pay attention so that fouling of the road bed doesn’t occur. c) For the river channel from Gunung Sahari to Ancol, there is extremely dense traffic, please be careful in transporting sediment, and it is suggested this be done at night. 11. North Jakarta Neighborhood Council a) Socialization b) We request that the Neighborhood Council be the oversight body to represent the community. c) Please have a Coordination Post, and station people responsible for community complaints. d) Public Works should plan the setback distance of residential buildings from the river channel at approximately 30 meters, to protect the water quality and conserve the river.
12.
13.
Regional Water Supply Company Operator AETRA a) To prevent interference and possible destruction of buried utility water distribution pipes that cross the rivers at the project work sites, it is best to carry out technical coordination in advance between the proponent/contractor and the Regional Water Supply Company (AETRA/PALYJA), because a pipe break will have a direct and destructive impact on the community, both in the vicinity of the site and at other locations. b) There needs to be a Post Office Box for complaints from the community to anticipate and assist any residents who want to submit complaints. Department of Public Works Response (Bambang Sigit) a) The dredging activities will be an effort to control flooding, with the methods of; - Empowering the community - Installing disposal bins along the channels/rivers - Implementing solid waste management with the principles of selectivity, inclusion, and concern for the community. b) The reasons for selecting these five (Phase 1) locations for the JEDI Project are, among others: - Social aspects are not particularly significant - Technical aspects can be implemented. c) We will form a functional body for community complaints. d) Design planning is being conducted simultaneously with the EIA. e) Contractors will be instructed to establish staffed environmental management posts.

Need complaint receiving center (PO.BOX) for community that would like to complain about the project. 13. Ir. Hesti D. Nawangsidi, MSP Generally, AMDAL for dredging of river and canal in DKI Jakarta Phase 1, 1. prepared by PT ERM Indonesia with the proponent Directorate general of Water Resource, MPW needs revision that focuses on the following: - In the TOR of the AMDAL (KA - ANDAL), it was agreed that the AMDAL study will only assess relevant aspect and component. Assessment that has been carried out has not yet been contextual, the study needs to include more detail information and assessment on the dredging and transportation impact. The assessment also needs to be structured to exclude information that is not relevant or necessary. - The purpose of ANDAL, RKL, and RPL is to support the proponent in carrying out the project, thus the documents produced by the consultants needs to be more practical. - Impact prediction which is the main part of the AMDAL has not fully included available data and information, more on qualitative assessment based on common sense, therefore not detailed enough information is generated, e.g. what, how, how significant and where the impact will occur. Impact prediction can use analogy approach or logical assumption in case data and information are minimum. - Environmental management plan should be more practical, considering the urgency of the project. - Consultant needs to dig out more details data and information related to this project, considering that such source of data is very likely available DKI Jakarta. - Consultant needs to structure the assessment more integrated and focus, so that the information presented in the document is not such collection of description of environmental component and aspect but should be result of consistent analytical and synthesis process B

If there is no alternative (of the activity) to be assessed, the study should not force to include such alternative (Hal. II-19), in which in the following chapters does not provide further description and assessment of the alternative such as location of dredging, method of dredging and transportation, no-project alternative
Based on guideline of AMDAL preparation (PermenLH No. 08 /2006), the proponent should include project alternative. In the document, proponent has mentioned that there is no project alternative except those provided in the document

The environmental baseline has not provided information on condition and characteristic of the environment relevant to the dredging and material transport such as : - Component on spatial planning (Hal III.1 s/d III.3) has not provided information on land use plan of the 13 rivers (catchment) following dredging. - Component on hydrology is one of the most important in this study, generally has been included in sub-section of spatial planning but not detailed enough. Hydrology assessment need to behavior of the flood from time to time, location, size (of flooding area), and duration of the flood; changing of pattern (or return period), cause of floods (change is rain pattern, river slope, sedimentation, land subsidence, high tide (rob), occupation of the river embankment, and garbage load etc.); and effort that has been taken. - Sub chapter 3.1.2 on system of flood mitigation at municipal level (Hal. III-5 s/d III.7) does not explain the flood mitigation itself but more on wastewater and garbage. - Component on rain fall (Hal III-7 s/d III-8) does not provide enough information on the pattern and intensity of rainfall that is supposed to be one of important factor in this AMDAL study. Secondary data on rainfall at upper Citarum river catchment area and DKI Jakarta are likely available to support better analysis of this component.

that is prone to flooding. Explanation on terrestrial fauna is too much and unnecessary (Hal III20). If not relevant, should be excluded. - Explanation of religion and praying facilities(Hal III-28 s/d III-29) is not relevant. - Component of social and culture (Hal III-33 s/d III.34) is not relevant to this study. - Component on transportation (Hal III-37) needs more detail description on volume and pattern of daily traffic both weekday and weekend, so that the peak hour for each road section to be used by the project for dredged material transport can be obtained. Volume of traffic can be predicted considering the dump truck capacity and dredged material volume from each location 13. Response from PMU (Bambang Sigit) Dredging is one of flood mitigation effort, during the implementation, the A project will: - empower the surrounding community (e.g. labor recruitment) and encourage community participation in supervision - provide temporary garbage disposal facilities at each project site, that is to prevent community garbage entering the river. - involve local community in separation or sorting the garbage Reason to choose the five location of the Phase 1: b. - Social issue is relatively minor - technically feasible. Will form a public complaint center. c. DED will be prepared simultaneously as the AMDAL study progresses. d. Contractor will be requested to establish its own environmental e management section -

Input
Mrs. Hesti D. Nawagsidi Andal Sub Chapter The alternative study in Andal: remove, since there will not be further analysis 2.3 Page II-21 within the next chapter. Andal Chapter 2 After d) Dredging: Waste Segregation. Add as following: After the dredging, then waste segregation has to be carried out, dredged material is disposed in Bantar Gebang Final Disposal Site, sediment is disposed to West Ancol. The odor will be occurred if segregated waste is not immediately handled. Andal Sub Chapter Add dredged waste according to impact prediction matrix. 5.2.2.3 Andal Page III-12 The term ‘rainfall condition’ is incorrect, it should be ‘rainfall data’, it shows significant difference between wet and dry season. Such kind of information is important as an input for selection of dredging time, within dry seasons. Andal Page V-3 The impact on the city infrastructure, especially related to the presence of drinking water pipes belong to PAM Jaya/AERTA/Palyja lie above the river, should be predicted. Andal Chapter V
Impact prediction is better to be strengthened by environmental baseline data For instance on page V-4: Impact on Noise and Odor. The baseline data shows that noise level has exceeded the quality standard, whereas odor level is below the quality standard (page III-16). Such data should be the background information for impact prediction. Another example on page V-4 Impact on Surface Water Quality. The baseline data shows that the parameters which have exceeded the quality standard are COD, BOD, oil and grease, detergent, and organic compound, whereas TSS has not (data shows that the concentration is extremely below the quality standard). Another example on Andal page V-5: Dredging Impact on People Perception. The data shows that 98.6% of the respondents have positive perception (page III-42) and if any concerns, it’s related to the unclean environment (45%). Therefore, on the impact prediction on page V-5 it should be related to such concern, not about noise.

Input For environmental monitoring effort, particularly related to people perception and security, it can also be added as follow: - The installation of notice board, concerning the dredging activity and its locations before the activity begins. - The criteria of the installation of notice boards, for instance, are installed a month before dredging activity and is 1 km distance between each board. Environment Management Implementation is better to involve sub district repreesentatives of each location.
Impact Management on Noise and Odor: it is better to make SOP compliance as requirement for contractor who dredges. For instance, the dredging equipment meets the noise level standard, dredging equipment maneuver is based on SOP, immediately segregate and drain the dredged material, dump truck must be waterproof, protector installation on dump truck load, et cetera. Impact Management on Surface Water Quality: - Installation of notice boards concerning the dredging activity also its locations, before the activity begins. - Dredging contractor requirements: dredging equipment meets the standard; dredging equipment maneuver is based on SOP. Impact Management on City Infrastructure: - The impact namely the disruption of drinking water pipes, property of PAM Jaya/AERTA/Palyja. - Management plan: Cooperate and coordinate with PAM Jaya/AERTA/Palyja for those infrastructures protection. Impact Management on Transportation: Contractor who carries the dredging production requires to: install special sign at the dump truck, the dump truck must be waterproof, protector installation on load, meet the carriage schedule (night time), queuing procedure, procedure of loading the dredge materials, maximum velocity. Written: Stakeholder at Regency level. DKI Jakarta Province has only Thousands Islands Regency, apart of it is Municipality. Please note the disturbing error-typed. Final document should be free from errortyped, for example on Andal page III-20 and III-30: must be corrected, including the words uppercase begins (Netherland, Government Regulation).

CHAPTER I INTRODUCTION
1.1
BACKGROUND Greater Jakarta is the political and economic center of Indonesia, with an estimated population of over 24 million. The city, with a population of about 9 million, is administered by the Provincial Government of Jakarta (Daerah Khusus Ibukota or DKI). The DKI lies in the delta of the Ciliwung River and about 40% of its area is below sea level. Every year, large parts of the city are flooded during rainy season, from November to April. The magnitude of the impacts caused by annual flooding in the Capital City has become a national issue due to the large financial losses and the impact on communities in the Jakarta area. To reduce the magnitude of the losses and damage caused by the floods, the Government of Indonesia has identified a series of flood control drainage canals, floodways and retention basins (waduks) that require urgent improvements. The rehabilitation of these structures will reduce the risk of flooding and bring direct benefits to the more than one million people who live and work in the areas prone to flooding. The Indonesian Government has requested a loan from the World Bank to finance the dredging and rehabilitation of the majority of the existing drainage system in Jakarta. One of the proposed projects is the Jakarta Emergency Dredging Initiative (JEDI) as included in the Jakarta Urgent Flood Mitigation Project (JUFMP), which aims to reduce sediment deposits in flood channels. These sediment deposits have reduced the design capacity of the drainage canals, floodways and waduks by half. One of the JEDI Project activities is the dredging of 16 drainage structures. The project proponents, the Directorate General of Cipta Karya (DGCK) and the Directorate General of Water Resources (DGWR, Sumber Daya Air = SDA) Department of Public Works (Departemen Pekerjaan Umum = DPU), and DKI Jakarta Government, have responsibility for: 1. Three drainage canals of national importance under DGCK authority: (i) Tanjungan, (ii) Lower Angke, and (iii) Cideng-Thamrin. 2. Three floodways under DGWR authority: (i) Cengkareng, (ii) West Banjir; and (iii) Sunter. 3. Five drainage canals under DKI authority: (i) Ciliwung-Gunung Sahari, (ii) Sentiong-Sunter, (iii) Grogol-Sekretaris, (iv) Pakin-Kali Besar-Jelakeng, and (v) Krukut-Cideng.

I-1
4. Five retention basins (waduks) under DKI authority: (i) Pluit, (ii) North Sunter, (iii) South Sunter, (iv) East Sunter III, and (v) Melati. For Phase 1 of the JEDI Project, 5 (five) drainage canals/floodways and one waduk have been selected to assess the planning, technical design, and environmental management approach to be implemented in all project sites. These sites have been selected because they are expected to produce relatively small environmental and social impacts but still achieve one of the project activity’s main objectives, and significantly beneficial towards the flood prevention efforts. The sites included in Phase 1 of the JEDI Project (Map I-1) are: 1. Cengkareng Floodway. 2. Ciliwung - Gunung Sahari Drainage Canal. 3. Sentiong – Sunter Drainage Canal. 4. Sunter Floodway. 5. Waduk Melati. Considering that the dredging activities will have positive and negative impacts to physico-chemical, biological, socio-economic, socio-cultural and public health components, an Environmental Impact Assessment is required for this project (Analisis Mengenai Dampak Lingkungan Hidup , hereafter referred to as AMDAL). The preparation of AMDAL documents adheres to the requirements of the Environmental Management Act No. 23/1997, specifically Article 15 on the AMDAL requirement for any activity or project with potential significant environmental impacts. In response to this law, the Indonesian Government enacts a Government Regulation (Peraturan Pemerintah) No. 27/1999 regarding process to conduct AMDAL. Furthermore, the Ministry of Environment (MoE) Decree No. 11/2006 lists specific activities that require AMDAL and the MoE Decree No. 8/2006 provides guidelines for AMDAL process. During the course of this project, the Environmental Management Act has been replaced by Environmental Protection and Management Act No. 32/2009 (relevant articles are 22-32). However, subsequent regulations to implement the Act No. 32/2009 have not been published. Therefore, the regulations adhered to in this study still refer to the Act No. 23/1997. In relation to the dredging works, MoE Decree No. 11/2006 specifies that any maintenance dredging activity in a city area will require an AMDAL if the dredged volume exceed 500,000 m3. The requirement is in line with the regional law (i.e. Governor of Jakarta Decree No. 2863/2001 on type and list of specific business and activities in Jakarta that require an AMDAL. The Decree states that any dredging activities with a volume more than 50,000 m3 must have an AMDAL. The anticipated volume of dredged materials from Phase 1 JEDI Project is 2,080,000 m3. The AMDAL documents have been prepared based on MoE Decree No. 8/2006 on Guidance on AMDAL preparation, and the AMDAL Terms of DREDGING OF FLOODWAYS/DRAINAGE CANALS & WADUKS PHASE 1 (JUFMP/JEDI)

Reference Dredging of Floodways/Drainage Canals and Waduks Phase 1 (JUFMP/JEDI) approved by DKI Jakarta AMDAL Evaluation Committee based on Decision Letter No. 48/KA/-1774.151 on 9 November 2009. To date, the project activities have not started. 1.2
PURPOSES AND BENEFITS OF THE PROJECT
1.2.1
Purposes The purposes of the projects are to: (i) increase the capacity of JEDI Phase 1 floodways, drainage canals and waduk through dredging work, (ii) minimize the impacts of annual flooding in DKI through the prioritization on rehabilitation and dredging of existing floodways, drainage canals and waduks, and (ii) provide technical expertise through the on-the-job training that strengthen the capacity of DKI and DPU to operate and maintain the flood control system, in accordance with international standards. The dredging activity Phase 1 is the preparation of the project, and will test the design technique of removing sediment deposits, transport and disposal of the dredged material, also monitoring and managing the anticipated environmental impacts.

PROJECT DESCRIPTION Based on Western Java Environmental Management Program (WJEMP) studies DKI 3-8 1 and centre 3-10 2, floodways, drainage canals and waduks (including drains and pumping stations) are in urgent need of rehabilitation through dredging and embankment works. Dredging activities will remove sediment that has occupied half of the designed capacity and reduced operational design from 25 to 2 years. In addition to dredging, improvement works on embankments and pumps are necessary. In 2004, surveys of the four major floodways indicated high levels of sedimentation and found urgent need to rehabilitate parts of embankment. In a number of places, embankment crest levels need to be raised to retain floodwaters. In other places, watercourses should be normalized, or embankments should be strengthened to prevent soil erosion entering the newly-dredged channels.

DREDGING OF FLOODWAYS/DRAINAGE CANALS & WADUKS PHASE 1 (JUFMP/JEDI)
II-2
Phase 1 of JEDI is a pilot project to minimize the impacts of annual flooding in DKI and to restore the design capacity of the existing floodways, drainage canals and waduks. The Phase 1 will concentrate on 4 (four) selected floodways/rivers/drainage canals and 1 (one) waduk, in Jakarta area, whereby the dredged materials will be disposed of in a designated disposal area. The locations are: •
Floodways under DGWR: (i) Cengkareng Drain, and (ii) Sunter (lower section).
•
Drainage canals under DPU DKI Jakarta: (i) Ciliwung-Gunung Sahari, (ii) Sentiong-Sunter.
•
Retention basin (waduk) under DPU DKI Jakarta: (i) Waduk Melati.
Dredging activities will include dredging of the sediment, transport to the disposal site and disposal of the dredged material. Dredging activities implemented in various locations will have different types and/or size of dredging equipment due to the wide variety of conditions presented by this project. Constraints that might affect the process and the selection of dredging method are the number of bridges crossing over each floodway and drainage canals. Based on inventory result, the total number of bridges which affect the project locations is shown on Table II-2. Table II-2 Numbers and Names of Bridges Crossing Dredging Locations No

Essentially, dredging is an act of excavating submerged or saturated sediment from one location and transporting it to another location. There are two main categories of dredging method (i.e. mechanical and hydraulic) with various configurations of each - from dredging the sediment from the bottom of the canal, and transporting the sediment to the disposal site. The following is a brief description of each dredging method: •
Mechanical Dredging:
Mechanical dredging generally uses type of bucket for the excavation of the under water sediment and bringing the sediment to the surface. Mechanical dredges are generally rated by the size of their bucket and can range from less than 1 m3 to greater than 40 m3. This method can excavate most types of material with the exception of the most cohesive consolidated sediments, coral, and rock. Figure II-1 shows a backhoe on a floating pontoon, used to dredge Jakarta’s canals under contract of DKI Jakarta. Figure II-2 shows a crane with clamshell bucket to remove waste from Lower Angke Canal. This type of equipment could be, in appropriate conditions, used for mechanical dredging to excavate material from the bottom of the canal. Mechanical dredges dump the bucket load within swing radius directly into a floating barge, or into a truck for haulage to the disposal site.

Figure II-1
Mechanical Dredging: Backhoe
A special type of mechanical dredging often used in the smaller urban canals is the floating bulldozer. Figure II-3 shows a floating bulldozer working in Jakarta. The floating bulldozer pushes the mud towards a land based excavator, which takes the sediment out of the canal and puts it in a dump truck. •
Hydraulic Dredging:
The most common hydraulic method is a centrifugal pump to create water flow that erodes and entrains sediment into slurry (water and sediment mixture). Hydraulic pipeline dredges are rated by the size of their discharge pipeline diameter and generally can range from 200 to 1000 mm. Sub-classes of pipeline dredges are defined by the mechanical and/or hydraulic attachments used to loosen and convey the materials at the bottom into the suction mouth. Plain suction dredges have no attachments on the suction mouth, while cutter suction dredges use a rotating array of cutters over the suction mouth, as shown in Figure II-4.

Cutter suction dredges (Figure II-4) are typically comprised of a hull, main pump and engine, ladder, suction pipe, cutter head, spuds, and hoisting and hauling equipment. The cutter head rotates to dislodge material from the bottom and water flowing into the suction mouth conveys sediment into the suction pipe. After flowing up the suction pipe and through the pump, the dredged material flows through a discharge pipeline to the placement site.

Hydraulic Dredging: Portable Cutter Suction Dredge
For dredging the floodways, drainage canals and waduk of the JEDI Phase 1 project, most likely only mechanical dredging techniques will be used, considering the condition of the canals and waduk, and the sediment to be dredged. 2.2.1

2.2.2
Project Phase Dredging works of floodways/drainage canals/waduk in DKI Jakarta will be divided into 3 (three) phases, i.e. pre-operations, operations and postoperations. Descriptions of each phase are as follows:
2.2.2.1
Pre-operations In this phase, activities will cover: a) Technical Design This AMDAL report is written while the technical design of the dredging works is still ongoing. Therefore it might be necessary during the AMDAL procedure to adapt the report based on new, progressing information received from the technical design team. b) Consultation Public consultation involving affected communities, private and nongovernmental institutions were undertaken on 19 August, 16 September and 29 December 2009. More details information on the public consultation is provided in Section 4.1.1.2 (Public Consultation) and Appendix 1.
2.2.2.2
Operations In this phase, activities will cover: a) Workers Mobilization In the operational dredging activity, there will be approximately 31-41 persons required for each location. Staff, both from contractor or subcontractor, does not stay in the project locations and they mobilize every day, while daily workers stay in a base camp on/around the project locations. Details of workers needed, can be seen in Table II-5. Hiring process for dredging activities will be done by contractors, and will involve local resources if qualifications and skills meet the requirement.

b) Heavy Equipment Mobilization Contractors will mobilize heavy equipment to the dredging locations as required. The types of equipment will be different per locations, but will basically consist of the equipment presented in Table II-6. Table II-6 List of Heavy Equipment for Dredging Activities List of Equipment Floating excavator (big and small) Floating Bulldozer Land excavator (big and small) Barges Tugboats Dump trucks Source: Sinotech (2009)
c) Transportation/Traffic Arrangement Traffic arrangement starts when heavy equipment is mobilized to the project locations. Once the dredging begins, trucks will be entering the dredging locations and trucks with dredged materials will go to the disposal site. In addition, parking arrangement for trucks and other project vehicles around project locations will be needed (while waiting for dredged materials). d) Dredging Dredging of floodways/drainage canals/waduk will most probably use mechanical equipment e.g. excavator on pontoon and barges (as shown in Figure II-7) with a small tugboat in the water and in the smaller canals a floating bulldozer. Dredging methods that will be implemented in each location will be adapted based on the characteristic of each location. Details are shown on Table II-7.

e) Separating Bulk Refuse Prior to transporting the dredged materials to the designated disposal area in West Ancol, it is necessary to undertake separation of bulk refuse materials such as large timber blocks. Separated bulk refuse will be transported to landfill facilities (i.e. Bantar Gebang) to avoid stench at dredging locations. Transporting bulk refuse to Bantar Gebang will be carried out in cooperation with private sectors as well as Dinas Kebersihan (Sanitation Agency) of DKI Jakarta and Sudin Kebersihan (Sanitation Sub-agencies) Central, West, and North Jakarta. f) Transporting Dredged Materials After loading the sediment directly into watertight dump trucks the sediment will be transported by dump truck to the disposal area. The distance between disposal area and dredging locations varies, generally up to 20 km. JEDI is responsible for transportation and dumping into the disposal area (see Figure II-8 for the illustration of dumping in land based disposal area) in the Ancol area, while the overall management of the disposal area will be under PT Pembangunan Jaya Ancol, Tbk. Transportation of sediment will be carried out by watertight trucks to prevent mud spilling onto the roads. Furthermore, fixed trucks routes will be arranged to and from the five locations. Predicted routes for each dredging location are as follows: •
Cengkareng Drain; Jalan Daan Mogot Æ Tol Æ Jl. Laks. R.E. Martadinata Æ Ancol
•

Figure II-8 Dumping with Dump Truck in Land Based Disposal Area g) Disposal Area Based on previous studies, the most viable option for Confined Disposal Facilities is at the eastern of West Ancol Stage I with an area of ± 119 Ha. The Government of DKI Jakarta through Governor’s Letter No. 1776/-1.793.43 dated 25 August 2009 regarding Dumping Site of Dredged Materials from 13 Rivers/Retention Basins in DKI Jakarta established the reclamation area in the eastern side of West Ancol as the Dumping Site/Disposal Area to receive dredged materials from 13 rivers and 6 waduks in DKI Jakarta. The Regional Environmental Agency (BPLHD) of DKI Jakarta has approved the Updating of RKL and RPL on the Development of Eastern Side of West Ancol of ±119 Ha based on the letter No. 02/Andal/-1.774.151 dated 30 March 2009. h) Land Cleaning and Rehabilitation During the dredging period, the locations for loading the dump trucks will be cleaned daily to remove any sediment spilled during the loading. After the dredging and transportation of the sediment are completed, any damages will be repaired and temporary removed infrastructure (e.g. fences) will be replaced as part of land rehabilitation activities.

2.2.2.3
Post-operations This stage covers the following activities: a) Heavy Equipment Demobilization Vehicles and equipment demobilization will be implemented in several phases from dredging location to disposal area, as set by the contractors. b) Workers Demobilization Before workers demobilizations starts, contractors need to notify all the workers. Demobilization can only be implemented after all parties fulfill each of their responsibilities. c) Dredging Maintenance The canals and waduk will be routinely maintained, considering the sedimentation rate in the canals, and especially the waduk, can be very fast. Therefore if the canals and waduk are not maintained routinely, the flow capacity of the canals and retention capacity of the waduk will become less than the design capacity which will mean an increased risk of flooding.
2.3
ALTERNATIVE ASSESSMENT This section presents an alternative assessment in dredging activities in floodways/drainage canals/waduk to mitigate flood in Jakarta. The alternatives will be selected based on environmental, technology and economic aspects. All alternatives will be considered before selecting the most beneficial and effective in terms of management, design and reducing impacts. •
Alternative Dredging Locations
Selections of floodways/drainage canals/waduk location which will be dredged in Phase 1 DKI Jakarta with regards to flood mitigation are based on the relatively minimum environmental and social impacts. •
Alternative Dredging Method
Selection of dredging method will consider the condition of dredging location and its surroundings (site specific). On some locations with less plastic garbage in the sediment like near the estuary of the Cengkareng Drain, dredging works might be executed with a cutter suction dredging equipment.

•
Alternative to Transport Dredged Materials
For transporting the dredged materials watertight dump trucks will be used in order to prevent soil/mud spilling on the roads or environment. Routes of the trucks will observe the road level and spots of traffics. •
No-project Alternative
If the dredging of floodways/drainage canals/waduk in DKI Jakarta to mitigate flooding is not implemented, flood risk will increase. The water capacity of the rivers in Jakarta will no longer be available to receive waters from upstream. This is also affected by sea level condition which can block the waterway to the sea. Meanwhile, if the dredging is implemented, the rivers capacity will increase to 50% from the existing capacity, therefore an expected alleviation of flood areas in DKI can be accomplished. 2.4
OTHER ACTIVITIES In general, other activities around study areas that will be affected are informal business activities such as transportation to cross the river (’eretan’), worm collectors (for fishing bait or fish food), horticulture on riverbanks, scavengers, motorcycle taxi drivers, etc). These informal activities include businesses along the river channels. Out of these activities, there are also fishermen and fish processing industries around the floodplains. Formal businesses affected include trading and traditional markets, offices, industries and warehouse are usually managed by employees who reside around or outside the project areas. To support formal activities, either for public or goods transportation, road access for transportation is necessary. Each area is also a trading area for other surrounding areas. The formal business activities can last for 24 hours a day. Communities around the project locations are potentially impacted by project activities. Generally, daily activities include working, going to schools, trading, industrial, etc. •
Cengkareng Drain
Based on preliminary assessment, there are approximately 824 affected people residing in 535 buildings in Cengkareng Drain area. Based on the building usage, activities around the location includes trading (55%), housing (24%), public facilities (3%) and a combined use like shop houses, office houses (18%). Specific activities along the riverbanks that will be affected include Kemiri traditional market, informal business, i.e. fishing baits collectors, crossing-the-river boats, and horticultures farming.

•
Ciliwung – Gunung Sahari
There are permanent and semi-permanent buildings along Ciliwung Gunung Sahari River which mostly are used for trading/business and offices. Therefore, community’s activities vary from businessmen to workers. Numbers of affected people in this area are relatively small and they are located around North and South Gunung Sahari, and West Pademangan. •
Sunter – Sentiong River
This is a relatively crowded location, where estimated numbers of affectedpeople are around 3,264 with around 816 units building which mostly are residences. Building use around project locations are for business/trading (1%), housing (69%), public facilities (3%) and combined use as shop houses and office-houses (27%). People activities around the project location include workers, technicians, and traders in local traditional markets, e.g. Sunter, Serdang and Sunter Mas. Other businesses in the area include bean curd (tofu) industry, building materials and florists. •
Lower Sunter
Based on its location, this river is split into three sections i.e. (a) Kelapa Gading residential gate at Jl. Perintis Kemerdekaan – Jl. Laksmana Yos Sudarso, (b) Cempaka Putih Intersection– Jl. Laksamana Yos Sudarso to Plumpang intersection, and (c) between Simpang Plumpang – Jalan Cilincing Raya. Many activities occur here especially in sections (b) and (c). Spaces between river block with inspection trails are mostly used for gardens, chicken farms, RT/RW Offices/Pos security or backyards. On several locations, there are also areas used as disposal sites. •
Waduk Melati
The location is surrounded by tall office buildings, hotels and trade centers. 78% of economic activities around the project are trading, while the rests are civic officials and workers. There are no social issues in this location.

CHAPTER III ENVIRONMENTAL BASELINE
Locations of Phase 1 of the JEDI Project are in 3 (three) administrative cities i.e. Central Jakarta (Sentiong-Sunter, Ciliwung-Gn. Sahari, and Waduk Melati), North Jakarta (Ciliwung-Gn. Sahari, and Lower Sunter), and West Jakarta (Cengkareng Drain). Environmental baseline conditions in these locations are described in this chapter. 3.1
SPATIAL PLANNING COMPONENTS Geographically, Indonesia’s Capital Jakarta is crossed by many rivers such as Mokervart, Angke, Pasanggrahan, Ciliwung, Cideng, Krukut, Grogol, Sekretaris, Cipinang, Sunter, Buaran, Cakung as well as swamps such as Badak, Buaya, Jati, and Mangun. The low land areas with elevation of -1.0 to + 3.0 occupy much of Central and North Jakarta, are natural retention basins. Watersheds of the above rivers form a river area in the shape of a mountain with Ciliwung Watershed at its peak (Figure III-1) (an area of approximately 150 km2). The geomorphology indicates that in natural conditions the large upland areas of Jakarta should not be flooded, as runoff from the upper basin spreads into large wetlands in the lower basin. This fact allowed the area to be the center of activities of Jayakarta Kingdom, later known as Batavia (during the Dutch colonial era), and currently known as Jakarta. In its present form, Jakarta no longer has sufficient number of deltaic wetlands and freshwater swamps. The remaining swamps have been converted into mixed-use residential and business centers, such as Pantai Indah Kapuk and Kelapa Gading. Jakarta also has no riverbanks as the main river channel has been narrowed due to its residents’ activities. The bottom line is that Jakarta does not have a proper drainage system. At the center of the basin where rivers enclosed Jakarta is the City of Depok, Regency/City of Bogor, which also has a large population, and extensive residential areas such as Cibubur, Sawangan, and Bekasi. Rapid and widespread residential developments in the mid-basin river area caused the disappearance of lakes, flood plains, and open/protected lands (water infiltration areas). Large areas in the upper Ciliwung River Basin include Bogor, Puncak and Cianjur districts (BOPUNJUR) have been converted to villas and other housing purposes (1000 new villas since 2000). This resulted in a further reduction of river catchment areas as flood control system in DKI.
DREDGING OF FLOODWAYS/DRAINAGE CANALS & WADUKS PHASE 1 (JUFMP/JEDI)
III-1
From the above descriptions, it can be concluded that geographically Jakarta is a strategic area, close to the sea, and can serve as center of activities (residential, government and business) with easy access. However, due to uncontrolled land use planning Jakarta has no flood control capacity. Jakarta experience major floods in 1621, 1654, and 1918, and further in 1976, 1996, 2002, and 2007. Flooding in 1996 covered almost all parts of Jakarta and became a national tragedy that attracted international attention. Major floods are expected to occur every 5 years. In early 2002 and 2007, Jakarta experienced major flooding covering more and more area. •
Basically, Jakarta has become a flood-sensitive area due to:
•
Influx of water that exceeds the discharge capacity of the rivers.
•
Insufficient drainage capacity and lack of water catchment areas in Jakarta.
•
Difficulties in rivers maintenance as most riverbanks have been converted to residential areas.
•
Poor waste management system and lack of public awareness in environmental hygiene.
•
Environmental deterioration in catchment areas due to uncontrolled land use.

River and Major Drainage System
3.1.3.1
General Drainage system of DKI Jakarta is consisted of from major and minor rivers also drainage system including supporting infrastructure. For the purpose of this project, the institutional responsibility for each river and drainage system shall be determined. Generally, two institutions are responsible to manage the river and drainage system i.e.: a. Central Government (Department of Settlement and Regional Infrastructure-Development of Ciliwung-Cisadane Area [Proyek Induk Pengembangan Wilayah Sungai Ciliwung-Cisadane = PIPWS-CC] responsible for rivers and major drainage system in DKI Jakarta. b. Regional Government (DKI Jakarta) responsible for major drainage system and internal drainage system.

*Major drainage considered as river Cengkareng System At the western area of DKI Jakarta, Grogol, Angke and Pesanggarahan floodways join together and flow to Cengkareng Drain which ends in Java Sea. In addition to the above mentioned floodways, Kali Mookervart, a tributary of Cisadane River also flows to Cengkareng Drain. West Canal Floodways System Almost all water from Ciliwung River is directed to West Canal Floodway trough Manggarai floodgate. Rivers from Krukut Dam and upstream area of Kali Angke is also directed to the West Canal. The responsibility for Ciliwung River at the upstream area of Manggarai Dam including the West Canal Floodway is fall under Central Government (PIPWS-CC), while the downstream area of Ciliwung River from Manggarai Dam to the North is a drainage system directing local flood water to Java Sea. This section is fall under the responsibility of DKI Jakarta Government.

Sunter System Kali Cipinang connects with Kali Sunter in the lower area and flow to Java Sea trough Tanjung Priok Port. To maintain the water level during rainy and dry seasons, water level at this system is monitored and managed through various water gates. Cakung System The Jati Kramat and Buaran Rivers merged to form Kali Buaran which also merges with Cakung Drain, which is a man-made river to channel down Cakung Lama River. Cakung Drain also flows to Java Sea. Currently East Canal Floodway is under construction. In the future, the Floodway will accommodate water flow from upstream area of East Jakarta such as Kali Cipinang, Kali Sunter, Kali BUaran, Kali Jati Kramat and Kali Cakung, and discharge it to the Java Sea. 3.1.3.3
