REPORT OF ENVIRONMENTAL IMPACT STATEMENT 1-1
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
1.1. Background
Tanjung Perak Port is definitely the second largest port in Indonesia and
extremely potential to support the traffic of goods from and to the Eastern
territory of Indonesia. Due to the getting increasing activities in Tanjung Perak
Port, PT. (Persero) Pelabuhan Indonesia III plans to develop facilities in
Tanjung Perak Port. In the mean time, the area required for such port
development is obviously limited. Accordingly, it is planned to develop the
port facilities in Lamong Bay.
Tanjung Perak Port development in Lamong Bay is exclusively for container
terminal construction for anticipating the getting increasing container
transportation activities due to global market demands.
With reference to the Regulation of State Minister of Environment Nr. 11 Year
2006 about Business Line and/or Activities to be provided with Environment
Impact Assessment (EIA), the Tanjung Perak Port Development in Lamong
Bay is to be provided with EIA. In view of the aforementioned, in attempt to
develop Tanjung Perak Port in Lamong Bay, it is provided with EIA that has
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 1-2
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
been provided with EIA in year 2001. The EIA was approved by the Central
Communication EIA Commission with an approval Nr. KP.137 A Year 2001
on 04 May 2001. Unfortunately, to date the required area for the proposed
development is still inadequate. With reference to State Regulation Nr. 27
Year 1999 about Environmental Impact Assessment (EIA), the approval on
the EIA of Tanjung Perak Port Development is out of date since the
development was not yet realized within 3 (three) years‟ time as of the date of
the approval. Therefore, in order to execute Tanjung Perak Port Development
plan in Lamong Bay, it requires re-application for EIA approval from the
competent authorities.
The EIA covers studies in to what extent the impacts, both positive and
negative ones, that may arise from a business line and/or activities to the
environment The positive impacts are to be maximized, while the negative
ones are to be minimized I order to prevent decreased environment quality.
The application of this EIA is supposed to support sustainable eco-friendly
development.
1.2. Objectives and Benefits of Tanjung Perak Port Development in Lamong
Bay
The objectives of Tanjung Perak Port Development in Lamong Bay are :
Reducing operation density in Tanjung Perak Port, especially for container
loading and unloading and anticipating any possible over capacity;
Cutting down vessel queue for mooring in the port in case of stagnation
leading to negative impacts to port image in international forum;
Creating job opportunities during and post construction phases, i.e. :
sustainable port operations through economic activities;
The benefit generated from Tanjung Perak Port Development in Lamong Bay
is to support national development, specifically for smoothening port activities
undertaken by PT. (Persero) Pelabuhan Indonesia III. In addition, economic
sectors in areas surrounding Tanjung Perak Port are supposed to develop.

Project Implementation : Studied Pre-Construction Phase, Construction
Phase and Operation Phase
In the project implementation, generally there are activities predicted to brig
impacts during the planning, construction and operation of the project. The
activities can be classified into pre-construction activities, preconstruction
activities and operationactivities. Prior to the Environmental Impact
Assessment preparation, there had been public consultancies on 16 January
2008 (Asemrowo Sub-diustrict), 18 January 2008 (Benowo Sub-district), 21
January 2008 (Krembangan Sub-district) and publication in Republika
Newspaper on 15 December 2007.
The details of the activities in each of the phases are further described as
follows:
A. Pre-construction
Sosialization
The socialization of the project plans is supposed to expose the
project to the public and explain the environmental management
and observation measures to be taken in the line with the project
plan implementation. The socialization is addressed to the peopke
dwelling surrounding the project site and predicted to be impacted
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 2-9
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
by the activities. The socialization covers the whole project activity
plans for the container terminal development in Lamong Bay.
The socialization activities are arranged as follows :
1. Approaching the fisherman public figures or fisherman
societies;
2. Collecting the public complaints and expectations in relation
with the project activities and communicate them to the
management and relevant government authorities;
3. Holding regular meetings with the community, PT. Pelabuhan
Indonesia III and relevant local government
4. Socializing the project activities plans to the community and
fishermen concerning the activities possibly affecting their
activities (such as : reclamation, pier strcture construction, etc.)
The issues to be discussed in the socialization cover the following
topics :
1. Activity plans on area preparation, reclamation for constructing
road/causeway, transportation of material and equipment and
bridge structure;
2. Activities to manage the negative impacts predicted to arise
from the project;
3. Needs of labors during both construction and operation phases;
4. Notification about locations to be set free from fisherman
activities;
5. Compensation that may be grantable (For instance : public
facilities).
B. Construction Phase
Construction Preparation
Labor Mobilization and Demobilization : Local and Migrant
Labors
Labor mobilization will be conducted in accordance with the need.
The project will need about 100 comprising : 80 skilled workers
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 2-10
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
and 20 non-skilled workers. The hiring will be prioritized for the
local people in accordance with the required qualifications. They
will be hired during construction phse only on contract basis.
Material and Equipment Mobilization and Demobilization
Material and equipment mobilization and demobilization for
preparing the construction of connecting bridge, pier structure and
trestle are highly potential to bring negative impacts to the traffic
on the roads accessed by the material and equipment transporting
trucks. The addition of heavy trucks operated for material and
equipment mobilization in the container terminal development in
Lamong Bay will be about 10 – 15 units of trucks per day. For
transporting the material and equipment to the project site, the
operated trucks will access the Toll Road and Jalan Tambak
Osowilangon until reaching the project site.
The works will adopt cast in situ construction method. The
reinforcing metal bards will be directly brought and set on site,
while the concrete mortar will be prepared by ready mix trucks.
The piles are made of steel . The materials for contructing the
connecting bridge , pier structure and trestle will be transported by
pontoon once a week.
Basecamp Construction.
The labors working and staying in the basecamp will be hired by
the project contractor. The basecamp is constructed on access road.
At present, it is close to Jalan Raya Tambak Osowilangon. The
basecamp is provided with public ashing, bathing and toilet
facilities.

Reclamation for Preparing Causeway Construction
The reclaimed area for constructing the causeway will be 500 m length
and 140 m width (total 70,000 m2) protruding to the sea. The
construction of the causeway will be quarry with volume + 173,000m3.
The cut of cross section of the causeway is presented in Figure 2.4.
Figure 2.4. Typical Cut of Cross Section of Causeway Source: Survey Investigation Design (SID) Container Terminal Development II in
Lamong Bay, Tanjung Perak Port, Surabaya, 2008
The causeway is constructed by reclaiming the shallow waters in an
average depth of + 0,0 m LWS and height up to 7 m. The quarry material
for the causeway construction is supplied by third parties that already
have environmental documents. One of the alternatives of supply of
quarry material is from the collected mud from the dredging of Shipping
Routes in West of Tanjung Perak Port (dredging for widening and
deepening the shipping routes). The quarry material criteria requires that
it contains 20% of mud (based on criteria in Surabaya Container
Terminal). The reclamation material is supplied from the quarry by
means of barge provided with suction unit and pipes to flow the material
to the location of the causeway as it is in shallow water area. Office
buildings and parking lots will be constructed on the causeway.

Shallow Water Reclamation for Container Yard Construction
The shallow water reclamation requires holistic planning as it is closely
related with detailed designs of each part of the structure. In general it
covers riprap construction and shallow water reclamation. The quarry
material is the mud collected from the dredging of shipping routes.
In general, the methods of shallow water reclamation are described as
follows :
Reclamation Material Transportation by Sea
In this activity, the quarry material is transported by means of
Trailling Suction Hopper Dredger (TSHD) and Cutter Suction
Hopper Dredger (CSD). The total volume of the reclamation
material is 5,844,000 m3. In case the production capacities of TSHD
and CSD are respectively 400 - 500 m3/hour and in case the capacity
of one barge transporting the reclamation material is 10.000 m3, there
will be increased sea traffic by 10 vessels per day, crossing the
shipping routes in Tanjung Perak Port during + 2 months for the
trnasportation processes. The quarry material for the causeway
construction is supplied by third parties that already have
environmental documents. One of the alternatives of supply of
quarry material is from the collected mud from the dredging of
Shipping Routes in West of Tanjung Perak Port (dredging for
widening and deepening the shipping routes). The quarry material
criteria requires that it contains 20% of mud (based on criteria in

Surabaya Container Terminal). The reclamation material is supplied
from the quarry by means of barge provided with suction unit and
pipes to flow the material to the location of the causeway as it is in
shallow water area.
Area Preparation and Compaction
It is a process of compaction of the reclamation in to an area ready
for constructions.
The works comprise :
a) Preparation Works
It covers the gains of licences required for the area to be
reclaimed, equipment mobilization, installation of signs and
border poles of the reclaimed shallow waters.
b) Geotextile Installation (made of synthetic materials for soil
strengthening). In order that the reclamation construction is
stable, it requires geotextile installation in layers. The thickness
of each layer is to conform with the needs.
c) Embankment Construction
The embankment is constructed with rocks supplied by third
parties. The volume of the rocks is + 25,000 m3 to be transported
by 10- 15 trucks per day each with loading capacity + 10 m3.
The trucks operated have to first pass emmission test. Next, the
rocks are arranged along the borders of shallo watersto be
reclaimed in order to prevent quarry material overflow out of the
set borders.
d) Soil Monitoring Instrument
It is required to monitor the reclamation volume, settlement and
sliding, especially during the process of embankment
construction. The instruments to be used for monitoring cover :
Settlement plate
Inclinometer
Piezomete
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 2-15
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
e) Shallow Water Reclamation Works
The reclamation is processed by pouring the quarry materials
into the reclaimed area steadily until it reches the expected
elevation. Next, the reclamation is leveled and compacted.
f) Vertical Drain and Horizontal Drain Installations
The vertical drain is for accelerating the draining. It is settled
on the ground by means of piling equipment provided with
special tools.In order to be able to accelerate the drain of water
of of the reclamation area, it requires horizontal dran (sand).
g) Compaction Works
The compaction requires vibrator rollers. The number of
required lanes depends on the permitted compaction
requirements.

Container Loading and Unloading
The operation of container terminal in Lamong Bay will entail
container loading and unloading activities.
In the loading and unloading activities, commonly the containers
are to first transit in the container yard before being transported to
vessels for loading operations or to trucks for unloading operations.
The container terminal capacity is 1,6 million TEU‟s per year, and
it is estimated that there will be increase of vessel accesses by +
530 vessels per year or + 2 vessels per day. Tanjung Perak Port
Development is supposed to anticipate container loading and
unloading up to year 2030. Next, it will be developed by
constructing a new port in Tanjung Bulu Pandan, Bangkalan,
Madura (Results of Study by JICA 2007, The Greater Surabaya
Metropolitan Port).
Container Terminal Operation
The containerterminal operations cover the operations of container
yard, gates and other supporting facilities , such as : Container
Freight Station (CFS), office building, gate and truck parking lots.
Distribution of Containers
As a center of distribution of goods, it will turn into a center of
cargo containers in East Java Province. As a center of distribution,
it will be much accessed by incoming and outgoing semi trailer
trucks, especially transporting cargo containers. The traffic volume
on the highways in the studied area accessing Jl. Tambak
Osowilangon - Jalan Romokalisari – Romokalisari Toll Road Gate,
will be + 60 trucks per day or + 8 trucks per hour. At present Jl.
Romokalisari is already provided with 4 lanes 2 ways with road
median in the middle of the highway (4/2 D) and Jl. Tambak
Osowilangun has already provided with 6 lanes 2 (6/2 D) with
road median in the middle of the highway. Accordingly, it will not
affect the average road performance significantly, i.e. : 0.8.
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 2-22
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
Ballast Water Supply and Oil Spill
The ballast water is commonly filled after the vessels have
completed unloading operations to balance the vessels. Such
operations seldom take place in Tanjung Perak Port since, mostly,
vessels having completed unloading operations, they will be
straigtly loaded. Therefore, in general ballast water filling
practically is not required. The oil usually spills during ballast
water draining. The process ballast water draining is to adopt
reception facility (RF). The container terminal in Lamong Bay
share the same RF available in Tanjung Perak Port in Nilam Barat.
Waste Treatment in Tanjung Perak Development in Lamong Bay
The waste treatment in container terminal in Lamong Bay utilizes
the same waste treatment plant already available in Tanjung Perak
Port. The treated wastes cover :
Solid Waste
The treatment of solid wastes in the container terminal will utilize
the same waste treatment plant already available in Tanjung Perak
Port. The rubbish from the container terminal will be transported to
and dumped in Benowo Landfill, so will the rubbish collected from
the pools or pier waters. (See Annex of Working Plan and
Technical Requirements for Transportation of Rubbish Collected
from the Port to Benowo Landfill)
Liquid Waste and Dangerous and Hazardous Waste
The liquid waste and dangerous and hazaordous wasstes from the
container terminal will be treated in the same Reception Facility
9RF) available in Tanjung Perak Port in Nilam Barat. Pursuant to
Annex IVMARPOL 73/78 Regulation 10, the port administrator or
management is to provide RF in accordance with the vessel needs.
The operation of RF is to refer to the relevant local regulations. In
Indonesia, the RF operation procedures are provided in the
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 2-23
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
Regulation of the Minister of Environment Number 05 Year 2009
about Waste Treatment in Ports (annexed thereto). The RF
activities cover collection and storage of dangerous and hazardous
wastes, and waste treament facilities, such as oil separator, Waste
Water Treatment Plant (WWTP) and residual landfill (such as :
incenerator). The RF operation is not yet optimum as it has not yet
been legally protected by Sea and Coast Security Guard (KPLP) by
means of a regulation obliging each vessel to utilize the RF,
especially for handling used oil or dangerous and hazardous
wastes). The RF Operation Permit is presented in Annex 3.
Port Security Management
The port security in the container terminal in Lamong Bay will be
managed under the same standards as the ones applied in Tanjung
Perak Port. Tanjung Perak Port management has applied the
international standards to manage the port security and facilities
under International Ship and Port Facility Security (ISPS Code)
since 1 July 2004, and they periodically provide security trainings
to be attended by the relevant security officers. The trainings
provided in consistence with the ISPS Code involves KP3 Tanjung
Perak, Indonesian Army Officers, Indonesian Navy Officers,
Tanjung Perak Port Security Unit, PT Pelindo, Fire Extinguishers
and companies operating in the port.
Tanjung Perak Port that serves foreign vessels, is strictly to follow
the international security procedures as set forth in the ISPS Code.
In order to be able to well support the port security and facility, it
requires trainings. In the mean time, to assure better services and
sense of security, as of 01 July 2004 all ports, especially the ones
serving foreign vessels is to apply the ISPS Code. The consistant
application of ISPS Code in Tanjung Perak Port, is initialized by
preparing the required human resources and physical supports in
the port, such as : Close Circuit Television (CCTV), street lights
and fences.

Referring to the aforementioned Table, it shows that the highest container
traffic growth rate was 11.36 % per year in year 2003-2004 in Boxes. At
present, the vessel visit to Tanjung Perak Port accesses the same shipping
routes as the ones accessed to container terminal in Lamong Bay. The
operation of container terminal in Lamong Bay will decrease the voyage safety
in the shipping routes in Tanjung Perak Port.
Fish Landing Base Plan in Surabaya City
Surabaya City Development Agency plans to establish a Fish Auction Center
- Fish Landing Base in the estuary of Lamong Bay. However, tit is notyeat
clear when such plan will be realized. (See Figure 2.16). The possibly arising

impact will be increase of traditional fisherman boat traffic loading the
existing shipping routes in the West Part of Madura Strait.
Waterfront City Plan in Lamong Bay
Based on the information collected from the East Java Province
Environmental Agency, it is planned to establish a Waterfront City close to
Lamong Bay by a private entity. It is supposed to be a water tourist attraction
center. Theproject will be realized by reclaiming parts of Lamong Bay to
establish 2 (two) artificial islands, each with a total area of 116 Ha and 84 Ha
(See Sitemap in Figure 2.16).
The locations of the reclamation area are in two administrative territory of
Regency Government og Gresik (116 Ha) and City Government of Surabaya
(84 Ha). The project will possibly increase the surface elevation of backwater
in the estuary of Lamong River due to high tide.
Suramadu Bridge
Suramadu Bridge is in the East of Tanjung Perak Port and relatively remote
from the studied area. The East shipping routes at present are not the ones for
vessels about to tether in Tanjung Perak Port or Container Terminal in
Lamong Bay, since the contour of the routes is too shallow for vessels to
access. The location of Suramadu Bridge is presented in Figure 2.17.
Since the location is pretty away (+ 15 km) from the project site, and it is not
in the shipping routes to the port, it does not affect Tanjung Perak Port
Development in Lamong Bay.
Indonesian Navy Arsenal in Batu Poron - Madura
In Batu Poron, Bangkalan, Madura, there is an Indonesian Navy Arsenal. The
project will not affect the arsenal as its location is relatively remote from the

Air Quality
To identify the ambient air quality in the project site, the contents of gases,
such as Carbon Monoxide (CO), Nitrogen Oxide (Nox), Sulphur Dioxide
(SO2), and solid particles (dust) are measured. The gases are measured interms
of : air temperature, relative humidity. Wind speed, and wind direction. The
primary measurements are undertaken and analyzed by East Java Province
Company Hygiene and Occupational Health Center. The air quality and noise
measurements were conducted on 19 February 2008 in 5 (five) observation
points surrounding the studied area as presented in Figure 3.3. The climatic
conditions during the measurements are presented in Table. 3.2. and the
results of ambient airquality measurement are presented in Table 3.3.

Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
Refering to data presented in Table 3.3, the parameter exceeding the quality
standard is NOx, i.e.: in Jl Demak – Jl. Gresik Junction and Romokalisari
Crossroad. The dust exceeding the quality standards as set forth in the
Indonesian State Regulation 41 Year 1999 is found in Demak Junction,
Romokalisasi Crossroad and Margomulyo Junction. The concentration of
measured gases and dust is predicted to originate from fuel combustion of
automotive vehicles and traffic of automotive transportation activities. In the
locations of measurement, the mobile activities of human beings and goods by
means of automotive vehicles are relatively dense.
Noise
The noise sampling points and number of samples are the same as the ones for
measuring air quality measurement (See results in Table 3.4.).

Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
Based on the data presented in Table 3.5., it is found that, when compared to
the standards set forth in Decisison of Minister of Environment Nr. 51/2004,
the seawater quality is described as follows :
The seawater physical quality based on the result of measurement on
parameter of suspended solid, there is 1 location the quality of whicj
exceeds the standard quality, i.e. : waters in Lamong River (Location Nr.
1).
The seawater chemical quality measured in 10 measurement locations I
sin general satisfy the seawater quality standards in port area. Seaa
locations in Figure 3.4.
Referring to the aforementioned descriptions, it is conclusive that the
seawater in the studied area and its surrounding satisfy the quality standards
for port area.
The quite number of suspended solid in the studied area , especially the one
in Location 1 or in front of the estuary of Lamong River is due to the
sediment in Lamong River. It contains mud drawn by the river water and
accumulated in the estuary.
3.2.2. Borlog and Soil Stratigraph
Based on the results of “Study on Technical and Environmental Reviews on
Shipping Routes, Sedimentation and Reclamation in Coastal Area in Madura
Strait”, in the waters area of Lamong River with seabed depth –2.00 m LWS.
Averagely in 13 m thickness from the seabed, the soil layers are dominated
with clay and very soft silt with N-SPT value ranging 0 through 4. (See Figure

Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
3.3. Hydrology and Hydro-oceanography Components
3.3.1. Hydrology Aspects
Watershed
In the studied area there are rivers draining into Lamong Bay. They are
Lamong River, Krembangan River, Anak River, Greges River, Branjangan
River and Sememi River. They mainly serve as area drainages. The river
waterflows originate from the surrounding areas and household liquid wastes.
These rivers drain into Gunungsari Drainage System as they are connected to
Gunungsari Primary Drainage. Gunungsari Primary Drainage used to be
irrigation network that changed into drainage due to the change of drainage
areas in the farms into dwelling and industrial areas.
The characteristics of the small rivers resemble the ones of Lamong River.
Accordingly, the results of analysis on Lamong River apply to those small
rivers.
The initial descriptions of the rivers and watersheds are as follows :
a. Lamong River
Lamong River watershed is in the administrative territories of Surabaya
City, Resik Regency and Lamongan Regency. The water spring of
Lamong River is is Kendeng Mountain located in Lamongan Regency,
while its upstream through downstream serve as the borders between
Surabaya City and Gresik Regency.
The area of Lamong River watershed is 714.46 km2, with 7 tributaries.
The upstream area comprises teak forests, settlement area, and dry farms.
In the middle it is occupied for settlement area and dry farms. The
downstream area is occupied for settlement area, fishponds and industrial
area along the river banks.
The length of Lamong River is ± 83.70 km. The meanders are located in
Jono Village, Cerme Sub-district. The water width of the river channels
in the measured area (from the estuary through ± 20 km towards
upstream) greatly vary. In the upstream, it is ± 20 m with flood plain
depth ± 5m. In the middle, it is ± 70 m with flood plain depth ± 2,50 m.
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 3-14
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
In the downstream, it is less wide, i.e. : ± 60 m, with flood plain depth
2,50 m.
The main problems are Lamong River are flood and sedimentation, as it
is the final drainage to some parts of Gresik Regency, Lamongan
Regency and the areas surrounding the river. Floods in Lamong River
watershed always present in wet season every year. Based on the
Detailed Designs and Environmental Impact Assessment concerning
Lamong River in Gresik Regency, 2005, the largest floods or the highest
puddles were in January and March 2004. The puddled areas in Gresik
Regency covered Cerme Sub-district and Duduk Sampeyan Sub-district,
Cermenlerek Village Gorekan Kidul Village with puddle height ± 1,5
mand puddled ± 600 Ha farm and settlement area as presented in Figure
3.6.

River watershed is reviewed in terms of 6 sub-watershed as follows :
1. Jublang River Sub-Watershed
It is located in highland with watershed area of DAS 226 km² and
river length of about 39 km. In the upstream, there are many bushes
and tall and coarse grass growing on the river banks and serving as
rural drainage networks.
2. Gondang River Sub-Watershed
Gondang River is a tributary to Lamong River in the upstream with
watershed area of 17 km² and river length of 9 km. The river bed
width is averagely 18 m and the river channel is stright and relatively
low embankments.
In downstream, about 450m from the estuary, there is a side weir
station that still functions at the present date. It drain flood water
frequently flows into Mergayu Village. Unfortunately, the station is

mainly damaged, especially in the left side of the spillway top point
and downstream left wing.
3. Cermenlerek River Sub-Watershed
Cermenlerek River is located in Cermenlerek Village and Beton
Village. Its length is 8 km and the watershed area is 56 km². During
the wet season, the water flow rate is pretty high, while during dry
season, it is relatively zero. The right and left embankments of the
river is quite tall, about 3.0 m from the river bed. However, it does
not mean that the Cermenlerek River is always capable of storing the
flow rate of the water. In the downstream, about 250 m from the,
there is a 2 x 1,25 x 3,0 m water gate that, at present, still function to
drain the annual waterfow.
4. Menganti River Sub-Watershed
Menganti River Sub-Watershed is located in Bringkang Village and
Menganti Village, Menganti Sub-district with an area of 39 km² and
length of 10.5 km. It is meandering with average width of 20.00 m.
The right and left riverbanks are relatively low and incapable of
storing the annual water flows.
5. Iker-Iker River Sub-Watershed
Menganti River is a tributary of Lamong River and located in left
junction between Morowudi Village and Iker-Iker Geger Village,
Cerme Sub-district with watershed area of 39 km² and lenth of 10.5
km. The right and left riverbanks are relatively low and incapable of
storing the annual water flows.
6. Lamong Rubber Dam Sub-Watershed I
Lamong Rubber Dam Sub-Watershed I spread out in Lamong River
upstream with 7,700 m length from the estuary in Kedanyang
Village. The width of the rubber dam is 35.90 m with 3.00 m. height.
At present the rubber dam is not in operation to supply plain water
need in the upstream. Therefore it is flatten.

Lamong River is used for various purposes. In the upstream, where it is
not affected by salty water intrusion, the river water is exploited for
agricultural purposes, while in the downstream the water is exploited
for brackish water fishponds. The getting larger farms reduces the
forest area. The change of area utilization as forests into farms drives
greater erosion in areas drifting to the river. It, in turn, increases
concentration of sediment drawn into the river and accumulate in the
estuary or downstream. The sedimentation leads to shallowing in the
river channels and estuary. Therefore, during low tide, the fishermen
cannot sail to all parts of the river or estuary, rather than relatively
deep channels.

The area utilized for fishponds in the Lamong River watershed is
relativelt large. Although, there have been conversions of findponds
into industrial estates, the number of inlets of fishponds up to Jono
Village are still significant
The seawater flows (backwater) drain salty water into the river surface
and make the river water brackish and contain higher salinity
compared to the one from fresh water draining into the Lamong River
watershed. The local people use the salty water to fill their fishponds
to breed fish and shrimps and produce salts.
Lamong River is also used as a traffic facility among the fishermen
residing in Pojok Village, Tenapes Village and Jono Village.
The data of the cross section of the river resulted from the previous
study, from the estuary through 20 km towards the upstream are

b. Sememi River
Sememi River is the South of Lamong River. The main function of this
river is to serve as drainage for the surrounding areas. The water flow in
this river is influenced by the tide. In addition, the river also
accommodates the boat traffic. The upstream area comprises farms. In
the middle it is occupied for settlement area and dry farms. The
downstream area is occupied for fishponds and salt ponds. In the future,
the watershed area downstream will be ossuied for industrial and
warehousing businesses. Along Surabaya-Gresik Highway, there are
fisherman settlement areas along the riverbanks.
The water in the upstream of Sememi River is from Gunungsari Primary
Drainage, Babat Jerawat Drainage and South Sememi Drainage. The
flood in Sememi River watershed is found along Gunungsari Primary
Drainage running into Sememi River and surrounding Sememi River
section that is non-embanked. Gunungsari primary drainage with width
about 3 m is not yet strengthened with riprap. Besides, its elevation is

relatively shallow and its riverbanks are pretty low. In case of heavy
rains, such a condition always leads to water overflows
The worse is that, some residents in the South of Gunungarai Primary
Drainage, has holed the dams in the North to lower the floodwater
surface. Consequently, Jalan Raya Benowo is puddled longer and and
bear traffic congestion.
The channels in Babat Jerawat drainage with its upstream in Gresik
Regency are mostly natural. Only the ones found in real estate area are
embanked. The channels of Sememi River in the south area still natural.
c. Kali Branjangan (Kandangan)
In Surabaya City drainage networks, Branjangan River is called
Kandangan River.The chargacteristics and functions of this river are
similar to the ones of Sememi River. The upstream is located in
Kandangan Village, Benowo Sub-district. The area utilization is
indifferent from the ones of Sememi River, where fishponds spread
wide, although a few settlement areas are found (in the middle of the
area) and industries in some places. The waterflow in the dry season is
fully backwater during high tide.
Kandangan River is also a rainwater drainage for the surrounding area
and partly drains waterflow from Gunungsari drainage into the sea. Part
of the wter width of the river is covered with accumulated sediment.
Besides, a few narrowings on the water width of the river are found due
to bridge constructions, railways and aslant plumbing installations under
bridges.
The channel is still natural and not yet riprapped. The secondary
channels flowing into this river are :
- Made channel – It is stall a natural channel.
- Larangan channel - Partly, it is a natural channel, only a samll part is
riprapped
- Sambi Kerep channel – Most part has been riprapped with relatively
major sedimentation on the bed.
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 3-24
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
- Citra Raya and Citra Raya Timur secondary channel – It is fully
walled and riprapped and its dimension is widened by the real estate
developer.
The foolds from Gunungsari primary drainage cause puddles in
Kandangan River watershed and around the natural river section.
d. Greges or Balong River
In Surabaya City drainage networks, Greges River is called Balong River.
Greges River is also a drainage following into Lamong Bay. Most parts of
the river have been riprapped, yet still under capacity. There is nmuch
sediment flowing in the channel. On the right and lift river banks, there
are already many factory plants constructed and draining most of their
wastes into the river. It worsens the sedimentation problem in the Greges
River. In the upstream there is a slide water gate controlling the water
flow downstream. The secondary channels flowing into Greges River are
Margomulyo Secondary Channel, Darmo Harapan Secondary Channel,
Darmo Indah Secondary Channel, Lontar Secondary Channle, Gadelsari
Secondary Channel and Balongsari Secondary Channel.The flood puddles
in Greges River Watershed flows into Gunungsary Primary Drainage and
Margomulyo Secondary Channel due to narrowing river water wdth.
e. Anak River
It is a natural drainage with a lot of meanders and shallow water width.
The river water can overflow due to floods and high tide. Besides, it is
also accessed for fasherman boat traffic. The watershed is relatively small.
Most of the surrounding areas are fishponds. The settlement areas are
found along the riverbanks close to Surabaya-Gresik Highway.
f. Krembangan Village
It is a drainage for some parts of West Surabaya territory. The source is
from Morokrembangan water reservoir consists of two pools, South
Servervoir and North Reservoir. It is a temporary flood reservoir for
waterflows from the watershed before draining into the sea. The
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 3-25
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
waterflow in the reservoir is controlled by water gates and pumps. The
water flowing into the reservoir is from Greges Channel, Perak Channel
and Simo River. The reservoir is full of rubbish. Flood is present in
Gunungsari Primary Drainage due to the overflows from the upstream
when the flows enter the siphon and in the down stream between
Gunungsari Primary Drainage and Morokrembangan reservoir.
The problems of floods in Lamong River watershed and it tributaries are
typically indifferent from the ones in Surabaya City. Mainly, it is due to :
Heavy torrents.
Area topography and river angle downstream (< 1%).
Ineffective drainage networks and system and inconsistent with the present
spatial utilization concerning with surface erosion and rain precipitation.
There is specific reference for the water surface on streets and dwelling
areas and the ones in drainage channels.
There is no river provided with water gates to cope with back waterto the
river and channels.

project site will be close to the estuary of Lamong River and tidal area in
Lamong Bay and due to the reclamation for Water Front City Project, the
Flood and Sedimentation consultant and research team conducted bathymetry
surveys exclusively in Lamong River and tidal area in Lamong Bay in order to
find further details completing existing bathymetry.

Lamong Bay and surrounding river estuaries are shallow water areas during
high tide and surface areas during low tide.
During low tide, the wetted channels in the estuary of Lamong River are
apparent. In this shallow water area the angle of the seabed is slightly soping.
Towards the sea, some parts of Lamong Bay are included into the shipping
routes of Tanjung Perak Port. The channels are pretty deep, reaching 20 m
depth. The shift from shallow waters to the shipping routes forms relatively

Based on the results of calculation of the main tidal constants, the value of
Formzhal (F) can be identified to determine the tide in the studied area
(Defant, 1958). The value of Formzhal is determined by comparing the total
amplitude of components K1 and O1 and the total components of M2 and S2, or
in the following equation :
Equation :

Based on the calculated Formzhal value from the the tidal main constants, it
shows that the tidal type in Gresik is Mixed Diurnal Dominant Tide, where
in one day there is high tide once and low tide once. In case of neap tide, in
one day there are 2 high tides and 2 low tide. In Kenjeran the tidal type is
Mixed Semi Diurnal Dominant Tide, where in one day there are high
tidetwice and low tide twice with different heights. In case of neap tide, in one
day there is 1 high tide and 1 low tide.

Referring to the comparison of the important elevations in those two
observation points, it shows that the tidal elevation in Kenjeran is higher than
the one in Gresik. The studied area is in between the two observation points in
observation points Kenjeran and Gresik. Accordingly, when the mean of HWS
in Gresik and Kenjeran is adopted, the predicted HWS in the studied area is
+283,41 LWS. This elevation is supposed to be adopted as prime
consideration in determining the reclamation elevation.

3.4. Biological Components
3.4.1. Ecosystem Type
The planned project site for container terminal construction in Lamong Bay
comprises surface and coastal areas. The ecosystem consists of managed
ecosystem, i.e.: salt ponds and natural ecosystem, i.e.: mangrove.
3.4.2. Water Flora and Fauna
Plankton as Water Quality Bio-Indicator
Changes in water quality is closely related to water potencied in terms of
plankton abundance and compositions. The existence of plankton in an area
can supply information in regard with the conditions in the water.
Plankton is a biological parameter that can serve as indicator to evaluate the
quality and degree of fertility in a water area, i.e. : descriptions about the
amounts of living phytoplanktons in an water area and dominating
phytoplankton.
The samples of planktons are taken from 12 sampling points. Point 1 through
point 8 and point 12 are surrounding river estuaries. Point 9 through point 11
are inter-tidal area. All sampling points represent waters surrounding Mirah
Pier of Tanjung Perak Port (See conditions of sampling points in Figure 3.20).
a. Phytoplankton
The dominant phytoplankton in all samping points is Skeletonema sp. In
general, the kinds of phytoplankton found in each sampling point are
relatively indiferent. Saved for Skeletonema sp, the kinds of phytoplanktons
commonly found are Biddulphia sp, Dithylium sp, Chaetoceros sp,
Chaetoceros pseudocurvisetus, Coscinodiscus sp, Coscinodiscus radiatus,
Navicula sp, Pseudo-nitzschia sp, Oscillatoria sp, and Ulothrix sp. The
composition of the kinds, abundance and diversity index in each sampling
point are shown in Table 3.19.
It is idicated that some kinds of phytoplanktons causing red tide, such as :
Ceratium spp, Peridinium sp, Pseudo-nitzschia sp, Noctiluca sp, and
Triceratium sp are relatively not abundant, less than 5.000 individu/lt of
water. The red tide will take place when when the plankton abundance
reaches 2,000,000 individu/lt of water.
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 3-40
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
There are of patterns of domination in the sampling points surounding the
estuary and the sea. The most dominant phytoplankton in the sampling
points surrounding the estuary is Skeletonema sp (> 37%) and the one in
the sampling points in the sea is Volvox sp (> 49%).
Based on the phytoplankton diversity index, the structures of the
phytoplankton community in the studied area is slassified ‟stable‟ until
‟more than stable‟, with condition of waters classified ‟fair‟ to ‟good‟ The
highest diversity index is found in point 1 (1.98) and the lowest one in
point 3 (1.30) (See Figure 3.20).
The higher the diversity index is the more stable the community will be.
The more various species in a community, the more stable the community
will be. The more various species in a community is the more complex food
chain will be. The community with less species will have shorter food
chain, and this condition will make the community unstable. The loss of a
species may lead to the loss of other species. The loss of a certain species
can be favorable to the other species and lead to extreme abundance.

b. Zooplankton
In the studied area there are 43 species of zooplanktons found and
comprising : Crustacea, fish larva, gelatinous plankton, larva Mollusca,
larva Polychaeta, Nematoda, Chaetognatha, Protozoa, and Foraminifera.
The most dominant species is Copepoda Calanoida of Acartiidae family
and Eucalanidae as well as Brachyura larva (crab) stadia zoea (See Table
3.20).
Almost in all sampling points around the estuary, both economically and
uneconomically potential fish larva are found. Accordingly, it is probable
that the areas surrounding the estuary and mangrove in Lamong Bay are
hatching grounds and nursery grounds of fish. The existence of larva is
predicted to have relationship with the existence and abundance of natural
food of fish larva, i.e. : Copepoda (of Acartiidae and Eucalanidae families)
and other Crustacea, such as Cirripedia dan zoea Brachyura larva (crab).
Fish larvas bringing economic values are gereh/laosan (of Polynemidae
family), milkfish (of Chanidaefamily), tiny sea fish (of Atherinidae family),
belanak (of Mugilidae family), and lemuru (of Clupeidae family).
Based on the diversity index, the waters are categorized „fair‟ to good‟ with
relatively stable community structure. The highest diversity index is found
in point 1 and point 6 (2.21) while the lowest index is found in point 9
(1.41) (Figure 3.21).

Bentik Microfauna
The bentik microfauna sampling points are the same as the ones of plankton
sampling. There are 18 species of benthos found surrounding Lamong Bay,
comprising 11 species of epifauna and 7 species of infauna. The dominating
epifauna is Gastropoda (snails), such as : Astyris rosacea, Amphyssa
columbelliana, and Nassarius spp. The dominant infauna is Nereis sp, one of
the species of worm Polychaeta dan Gafrarium sp included into mollusk and
sheel (Bivalvia) (Table 3.20).
In general, the diversity and abundance if bentik microfauna in the studied
area is categorized low. It could be due to the condition of unstable muddy
substrate and containing oxygene (anoxic) and a lot of organic sedimentation.
There is no bentik microfauna found in in point 12. It could be due to its
position that is right in the estuary of Lamong River and there is no bentik
strong enough to stand the river water currents, turbulence and mixing due to
the mixing of riverwater and seawater masses.
The diversity index of bentik microfauna in the studied area is categorized
‟low‟ to ‟very low‟. Accordingly, it is concludable that the microfauna
community structure is not stable and very vulnerable to disturbances.

3.4.3. Terrestrial Flora and Fauna
Flora (Mangrove Vegetation)
The initial description of terrestrial flora is focused onmangrove vegetatio as
the project site of port development in Lamong Bay is in coastal ecosystem
and the representative and relevant terrestrial vegetation is mangrove.
Mangorove ecosystem is an ecosystem with tropical community vegetation
growing the coastal area and river estuaries. Mangrove ecosystem is affected
by tide and is sensitive to environmenta changes, such as : salinity, shallowing,
oil spills and sedimentation. The parameters adopted for observing the initial
conditions of the mangrove environment and ecosystem is vegetation density
per hectare (tree/Ha), Important Value Index and Mangrove Coverage
Area (%)
The analysis on mangrove vegetation is conducted in 8 observation point in
North Galang Island, South Galang Island, Lamong River Border, Sememmi
River Estuary, Branjangan River Estuary, Project Site, Greges River Estuary,
and Anak River Restuary. The mangrove vegetation is not conserved as the
mangrove conservation in directed to the Eastern Coastal Area of Surabaya
City, saved for Galang Island. The East Java Provincial Government plans to
plot Galang Island as a conservation area for coastal birds.
a. Density
Density is a comparison between the number standing tree ith
(ni) and the
total standing trees (∑n) in % (Decision of Minister of Environment Nr.
201/2004). There are 13 spcies of mangrove in the studied area and 7
sepcies of manggrove surrounding the estuary of Lamong River. 5 other
species, i.e. : Avicennia alba, Avicennia marina, Bruguiera gymnorrhiza,
Rhizophora mocronata and Soneratia alba are found in the project site.
Other species found in the study are completely listed in Table 3.23.

Density criteria and mangrove category (Decision of Minister of Environment Nr. 201/2004).
Density Criteria Trees/Ha Category
Dense > 1500 Good
Fair > 1000 - < 1500 Fair
Rare/Damaged < 1000 Bad
The tree density per hectare in the observation points are relatively good ,
i.e. : > 1.500 trees/Ha. Based on the mangrove species building the
ecosystem, the density of each vegetation species is different one another.
Some have relatively high density (> 1.500 pohon/Ha) and is classified
good, while the others are fair or rare/damaged. The species having fairly
good density are Avicennia alba in North Galang island , South Galang
island and Branjangan River and Greges River, Rhizophora mucronata in
project site and Soneratia alba in Sememi River Sememi. The species
having fair density is Rizhophora mucronata in Lamong River and Anak
River. (Figure 3.23)
REPORT OF ENVIRONMENTAL IMPACT STATEMENT 3-49
Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
The mangrove density in the project site that is pretty high is R. mucronata.
It is a mangrove species adapting with surface land. It is commonly used to
protect the fishpond embankments to stand erosion and sedimentation so
that the fishpond water keeps clear.

b. Important Value Index (IVI)
The mangrove species having relatively IVI when compared to the others
(>200) is A. alba in South Galang Island and A.marina in Greges River.
Fair IVI (> 100 - < 200) is found in A. alba in North Galang island and
Branjangan River, R. mucronata in project site and Anak River, and S. alba
in Sememi River. The details of the IVI are presented in Table 3.24.
A. Alba and A. Marina are the mangrove species having relative high IVI
when compare to the others, as Avicennia is a prioneer plant in the
coastalines and along the riverbanks affected by the tide and in highly
saline areas. The roots can help binding sediment and accelerate the
processes of land formation. Avicennia can be concentrated and form a
group in a certain haitat. It gives fruit along the year, and sometime is
vivipar in nature.

The imputs and recommendations given by the respondents in regard with
the development project plan in Lamong Bay are as follows :
1. Socialization about the port development project plan in Lamong Bay to
the community.
2. Priority to local people recruitment to partly cope with problems of
jobless people surrounding the project site.
3. Preventive measure pollution in the sea as it will lead to pollution in the
river and problems to fishermen‟s activities.
4. Socialization of Environmental Impact Assessment to fishermen before
commencing construction activities.
5. Road widening to anticipate traffic jam and street lighting.
6. No hindrance to fishermen‟s activities, especially during measurement
activities.
7. Provision of overhead crossing bridge.
8. No hindrance for fishermen to go fishing and sail under the connecting
bridge during high tide and project execution.
9. Compensation for fishpond owners whose fishponds are reclaimed. The
compensation rate is to be higher than the one for ordinary fishermen,
as they have exploited the fishponds for years.
10. Well considering and actively involving the local people. No
incompetent authorities in the port. Mutually beneficial to both the
community and government.

Sea Transportation – Voyage Safety
The initial descriptions about voyage safety in the studied area will be analogized
to the one in the existing container terminal, i.e. : Surabaya Terminal Peti Kemas
Surabaya (TPS), formerly named International Container Ternimal (ICT), and
passenger terminal in Gapura Surya Tanjung Perak. The shipping routes in the
studied area is commonly accessed by all voyages to and from Tanjung Perak
Port. The routes are free of mines and taccordingly safe to be accessed. The area
vulverable to mines are the ones out of the studied area, i.e. East of Kenjeran and
Karang Jamuang area (non shipping routes).
All vessels voyaging to and from the container terminal pier in Tanjung Perak Port
and Kalimas take the West routes in Madura Strait. The voyage schedules are
managed by the Port Administrator.
Based on the data of vessel visits in Tanjung Perak Port (see Table2.4.), it shows
that there is an average decrease of visits per year by 0.08%, with total vessel
visits as many as 15.459 in 2007.
The vessel accidents in Tanjung Perak Port are presented in Table 3.50.

Traffic Accident Rate
Jalan Tanjung Perak–Gresik is highly dense arterial road. This due to the fact that
it connect Surabaya as the Capital of East Java Province to other cities/regencies
in the North part of East Java Province, such as, Gresil, Lamongan, Tuban and
some others. Further, the warehouses established along the highways make the
traffic on that route denser with traffic of heavy trucks.
Jalan Gresik and Jalan Perak Timur as connecting roads to Tanjung Perak Port are
also dense with the traffic of heavy trucks incomming and outgoing Tanjung Perak
Port Surabaya.
In increase of traffic on Jalan Tanjung Perak Surabaya-Gresik leads to increase of
traffic accident. Along Jalan Kalianak–Jalan Tambak Osowilangon-Jalan
Romokalisari, as parts of Jalan Tanjung Perak Surabaya-Gresik, are the most
vulneravble to traffic accident. The issues in traffic accident requires serious
handling as it can bring significat losses and damages.
The results of study on Traffic Accident Analysis on arterial Jalan Arteri Tanjung
Perak Surabaya – Gresik route (Kurniawan, 2007), show that there are 3 black
spots in terms of traffic accident frequency. The points of the black spots are km
6-7, km 7-8 and km 8-9 on arterial Jalan Tanjung Perak Surabaya-Gresik (Jl.

Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
3.8. Spatial Aspect
The compliance of the planned project site to the Local Regulation Nr. 3 Year
2007 about Surabaya Master Plan is subject to condition that the studied area
to be completed with Environmental Impact Assessment is in the territory of
Surabaya City, covering 3 (three) sub-districts, i.e. : Benowo Sub-district,
Krembangan Sub-district and Asemrowo Sub-district.
In view of the city structure, the studied area is in the outskirt of Surabaya
City, in the North. In attempt to accommodate diversified interests, it requires
a comprehensive master plan well considering the utiilizations of land, water,
air and other natural resources in a dynamic and inegrated ecosystem.
Accordingly, Surabya City is divided into some Development Units. The 3
sub-districts in the studied area are in different Development Units.
Krembangan sub-district is under Development Unit V Tanjung Perak, mainly
functioning to develop port, special zone, strategic industrial zone, service and
trade with a center of development in Tanjung Perak area.
Benowo sub-district and Asemrowo sub-district are under Development Unit
XI mainly functioning to develop dwellings, trade and service and
warehousing, with a center of development in Tambak Osowilangon area.
Referring to the Sea Spatial Structure Plan, the studied area of Environmental
Impact Assessment is in Zone I. It is around the coastal area (Lamong Bay)
mainly functioning to develop port and shipping routes for large vessels. In
view of sea transportation development plan, Lamong Bay is projected for
international-scale container terminal and cargo development.
In Surabaya Master Plan it is stated that in the line with getting intensive cargo
loading and unloading activities in the exisiting terminal, it is impossible to
make extension due to space factors. Therfore, PT. Pelabuhan Indonesia III
plans to extend Tanjung Perak Port in Lamong Bay on the following
considerations :
The existing installed capacity in Tanjung Perak Port, i.e. : ±35 million
ton/year is to be improved as it is about to exceed. Accordingly, it is
reasonable to develop the port to the West.

Environmental Impact Assessment – Tanjung Perak Port Development in Lamong Bay
It is impossible to develop Tanjung Perak Port in the existing area, and it
is impossible to exploit upland as the location is heavily populated. The
only feasible alternative is reclaiming areas approved by the Minister of
Communication.
With reference to East Java Province Master Plan, Lamong Bay is projected
for developing an international port hub.
