1. Project Information

1.1 Project participants

The Project Sponsors are PT. Supreme Energy Muara Laboh (SEML), a company owned by Supreme

Energy, Engie Energy Asia Co., Ltd and Sumitomo Corporation. The Sponsors have secured finance for

the construction and operation of the Project from commercial banks, with Mizuho Bank, Ltd. (Mizuho)

as the mandated lead arranger (MLA), and the following international finance organisations: Asian

Development Bank (ADB), Japan Bank for International Cooperation (JBIC) and Nippon Export and

Investment Insurance (NEXI) (together the Lenders).

1.2 Project Location

The Project is located approximately 150km south east of Padang in the Solok Selatan Regency, West

Sumatra Province, Indonesia. The Project’s location and layout are presented in Figures below.

The Project area of approximately 140 hectares (ha) lies within the Liki Pinangawan Muaralaboh

Geothermal Working Area (Wilayah Kerja Pertambangan, WKP), which is situated along the trend of

the Great Sumatran Fault that runs parallel to the southwestern coast of Sumatra.

The Project is located in the Barisan Mountain range (Bukit Barisan) at an altitude of approximately

1,500 metres above sea level. The climate of this region is characterized by relatively heavy rainfall

throughout the year and the local area is prone to landslides during periods of heavy rain. The Project

is located in land that was previously used as a tea plantation and is adjacent to the Kerinci Seblat

National Park (Taman Nasional Kerinci Seblat, TNKS) which is a UNESCO world heritage site (Tropical

Rainforest Heritage of Sumatera /TRHS). Existing monitoring data for the site indicates that baseline air

quality, water quality and noise levels are good as would be expected in an area with little industry and

pollution sources.

There are several small settlements (Jorong) in the vicinity of the project site: Pinang Awan, Taratak

Tinggi, Kampung Baru and Pekonina. Although residential areas are all more than 1.5km from the

power plant and production wellpad areas, other project infrastructure such as reinjection wellpads

and access roads are located in close proximity to local communities.

Figure-2 : Project Layout


1.3 Project Summary

Following the completion of the access roads and 6 wellpads (ML-A, -B, -C, -D, -E and -H), SEML started

the exploration drilling which was completed in September 2013. To date, SEML has drilled six full‐diameter exploration wells at Muara Laboh (ML‐A1, ‐B1, ‐C1, ‐E1, ‐H1, and ‐H2).

GeothermEx (Lenders’ Resource Consultant) conducted a due diligence and estimated that the capacity

is approximately 60MW gross electrical based on single flash technology. In order to improve the

station capacity, and project economics, it was proposed that the Muara Laboh Geothermal Power

Project Stage 1 Development will utilize dual flash technology to increase the generation output to

approximately 80MW net.

Supporting facilities including the admin complex, staff accommodation, water intakes, temporary

water supply pipelines, yard and workshop areas and security posts have also been constructed.

Afer Financial Close (FC) in February 2017, the Notice to Proceed was issued to the consortium of

Sumitomo-Rekayasa Industri-Fuji on 24 March 2017 and the site activities started on 14 April 2017 to

clear the land for one new wellpad (ML-F) and its access road, power plant area, temporary contractor

site office and disposal area.

Eleven new wells will be drilled across five wellpads (ML-A, -H, -D, -E and -F). Drilling of ML-A2 was

commenced on 24 May 2017 with drilling rig from PT Plumpang Raya Anugerah (PRA). Second drilling

rig from PRA was utilized in August 2017 to drill ML-E2. Nine wells have been drilled, 1 well is being

drilled (ML-F1), and the last well (ML-F2) is still to be drilled.

The wellheads, together with the proposed pipelines, separators and other associated infrastructure

will form the Steam Gathering System (SGS). The proposed power plant to be constructed will

comprise one dual flash condensing steam turbine, eight-cell cooling tower, a switchyard and ancillary

infrastructure.

PLN is responsible for building the transmission infrastructure for the Project; the interface between

PLN and SEML’s responsibilities is the power plant switchyard. PLN proposed to construct a new

substation (Muara Laboh substation ; name is in lieu of Batang Sangir in the past) on SEML land

approximately 3.4km from the power plant and a new 150kV transmission line from the switchyard to

this substation; the substation would also provide connection for a separate local hydroelectric project

and potentially other power generation facilities in the local area. The 3.4km 150kV transmission line

from the power plant’s switchyard to the PLN Muara Laboh substation is considered as an “associated

facility” and therefore forms part of the Project.

The proposed transmission line route and substation location are shown in Figure below.

Land acquisition of the 150kV transmission line is due to commence in 2018 followed by physical

construction. Energization is in April 2019.

Environment Impact during the Project Phase:

Of the possible environmental impacts that maybe affected due to the on-going project activities,

increase in noise levels due to high levels of mobilisation and construction works is the most

apparent. Dust control can also become quite an issue with the high amount of vehicles coming in

and out of the project area. However, the project area is also known for high levels of rainfall.

Surface water and air quality, while can be impacted by the work is still rather less severe than

noise. Erosion while possibly impacted by the high number of mobility and rainfall seems to not

be impacted very much. PT SEML however, is continually monitoring such cases and opt to

implement the best possible corrective and preventive actions.

2.2 Key Developments and Major Changes in Location and Design

No major changes to location and design were made.

Priority SHE documents have been completed:

Ecosystem Service Assessment: the survey was conducted by ERM Indonesia in December

2017. Upon the survey, it was identified that Freshwater and Erosion Regulation were

identified as the Priority Ecosystem Services. Source of water from the area of interest is used

often used for irigation system and micro hydro development. Based on the survey, Muara

Laboh is also identified to function for regulating erosion on slopes and riparian areas within

the vicinity. The project shall make sure that its impact will not affect the mentioned services.

Water quality and quantity measurement efforts will be implemented by SEML accordingly.

Similarly, erosion regulation in the form of efficient / minimal mass soil movement and

landslide protection measures will be implemented accordingly. A similar approach is to be

applied for the lesser ecosystem services identified.

Aquatic and Macroinvertebrates Survey: the survey was conducted by ERM and the relevant

experts of the Biology Department of the University Andalas in in December 2017. Based on

the surveys performed, it can be concluded that the stream ecosystem within PT SEML’s project area is relatively undisturbed. This can be attributed to the number of

microinvertebrate species identified in each stream (19-27 genera). The number of individuals

also range from 95 to 206 with a moderate number of diversity index for each genera.

Measurement Points Number of locations will be determined later based on analysis of the observation data. The below are the previous locations during biodiversity study.

Flora Survey

Amorphophalus sp, an endangered species, was encountered prior to land clearing. The in-situ nursery for this species was developed upon consultion with biodiversity experts. The site is maintained on a regular basis.

Biodiversity Offset Program

Initial offset location join survey between SEML and TNKS was conducted on 21 July 2017. The participants were SEML environmental engineers, officers from the local Forestry department, and Forestry police from TNKS. Based on the initial survey, 5 potential locations were observed, namely: Sungai Lambai, Batang Bangko Keruh, Sungai Ipuh, Bukit Malintang and Bukit Jorong Sandar.

On 20 December 2017, PT SEML contacted the ICS (Local NGO) for a discussion regarding PT SEML’s plan to implement their Biodiversity Offset & Action programs. ICS has then been appointed to support SEML biodiversity offset program.

A report of the intitial survey was produced on December 2017 to compile early findings of the observation.

EXECUTIVE SUMMARY

PT Supreme Energy Muara Laboh (SEML) plans to develop a Geothermal

Power plant project in Muara Labuh in Solok Selatan Regency, West Sumatra

Province (the ‘Project’).

The development plans broadly comprise construction and operation of

geothermal power units, construction of supporting infrastructures, and

electricity distribution. These activities have potential to cause environmental

impacts.

The Asian Development Bank (ADB) identified that an ecosystem services

assessment was necessary to assist with compliance with the ADB’s Safeguard’s Policy Statement (SPS) in relation to the identification and

management of Critical Habitats. Previous assessments undertaken for the

SEML project had not specifically undertaken assessments for ecosystem

services. As a result, an ecosystem service assessment was identified as a gap

and an action as part of the SEML Biodiversity Action Plan (BAP) (ERM 2017)

(v.10 S/N 39).

Environmental Resources Management (ERM) was subsequently contracted to

undertake an ecosystem services assessment for the SEML site in August 2017.

ERM has completed this assessment in accordance with relevant guidance,

including the World Resources Institute (WRI) guidelines: Weaving Ecosystem

Services into Impact Assessment (WRI 2013).

In accordance with the WRI guidelines, ERM conducted ecosystem services

screening assessment in order to determine the likely ecosystem service values

that could be potentially important to affected communities. This assessment

was done using existing sources of data, including information gleaned

during the scoping visit. This visit was held in October 2017 and consisted of

initial interviews with Supreme Energy representatives in Muara Laboh, West

Sumatra site location as well as with local community representatives in the

following sub-villages: Blok Nol, Pekonina, Kampung Baru, Taratak Tinggi,

Pinang Awan, Ampalu, Pinang Sinawa, Koto Baru, and Tarak Bukareh.

There are three categories of ecosystem services that were found when ERM

conducted ecosystem services screening: (1) provisioning services; (2)

regulating services; and (3) cultural services.

For the provisioning aspect, the ecosystem services assessment included: (a)

Food: wild-caught fish and shellfish and aquaculture; (b) Food: wild meat; (c)

Food: cultivated crops; (d) Food: herbs and plants; (e) Livestock farming; (f)

Biomass fuel; (g) Timber and wood products; (h) Non-timber forest products.

For regulating aspect, the ecosystem services assessment included freshwater

utilization, soil control and forest protection. For cultural aspect, the

ecosystem services assessment included spiritual, religious or cultural value.

After conducting screening on ecosystem services prioritization, ERM

identified two priority ecosystem services that may be sufficiently impacted as


IV

to warrant mitigation. These ecosystem services included: freshwater and

erosion regulation.

ERM considered that SEML project may likely impact to these priority

ecosystem services. To reduce the impacts on the priority ecosystem services,

ERM has proposed specific mitigations. At the mitigation stage, ERM

identified options through the mitigation hierarchy to enhance or at least

maintain: (1) the well-being affected beneficiaries derive from ecosystem

services and (2) the performance the project derives from ecosystem services

at acceptable levels.

ERM has determined that the application of these mitigations is sufficient to

reduce the impact to these ecosystem services to negligible or minor. As a

result, no residual impacts have been identified on ecosystem services that

require additional mitigation and offsetting.

1 BACKGROUND

PT Supreme Energy Muara Laboh (SEML) plans to develop a Geothermal

Power plant project in Muara Labuh in Solok Selatan Regency, West Sumatra

Province (the ‘Project’).

The development plans broadly comprise construction and operation of

geothermal power units, construction of supporting infrastructures, and

electricity distribution. These activities have potential to cause environmental

impacts.

The Asian Development Bank (ADB) identified that an ecosystem services

assessment was necessary to assist with compliance with the ADB’s Safeguard’s Policy Statement (SPS) in relation to the identification and management of Critical Habitats. Previous assessments undertaken for the

SEML project had not specifically undertaken assessments for ecosystem

services. As a result, an ecosystem service assessment was identified as a gap

and an action as part of the SEML Biodiversity Action Plan (BAP) (ERM 2017)

(v.10 S/N 39).

Environmental Resources Management (ERM) was subsequently contracted to

undertake an ecosystem services assessment for the SEML site in August 2017.

ERM has completed this assessment in accordance with relevant guidance,

including the World Resources Institute (WRI) guidelines: Weaving Ecosystem

Services into Impact Assessment (WRI 2013).

1.1 DEFINING ECOSYSTEM SERVICES

Ecosystem services are defined as the benefits that people, including

businesses, derive from ecosystems (IFC 2012). These services are substantial

and varied, underpinning basic human health and survival needs as well as

supporting economics activities, the fulfillment of people’s potential, and enjoyment of life.

In order to provide a uniform basis to assess the status of all major global

habitat across all of the word’s bioregions, the United Nation’s Millennium Ecosystem Assessment (UN 2005) combine diverse Ecosystem Services

typologies into a consistent classification scheme.

There are four categories of ecosystem services defined in Millennium

Ecosystem Assessment as outlined in IFC Performance Standard 6:

Provisioning Services; these services that can be extracted from ecosystem

to support human needs. This term is more or less synonymous with the

term “ Ecosystem Goods” that was used in some prior classification schemes, including such tangible assets as fresh water, food, fiber, timber

and medicinal plants;

Regulating Services; the benefit obtained from an ecosystem’s control of the natural environment, including of the regulation of surface water


1-2

purification, carbon storage, and sequestration, climate regulation,

protection from natural hazard, air quality, erosion and pests;

Cultural Services; non-material benefits including diverse aspect of

aesthetic, spiritual, recreational, and others cultural value;

Supporting services; the natural process essential to the maintenance of the

integrity, resilience, and functioning of ecosystem, thereby supporting the

delivery of all other benefits. They include soil formation, nutrient cycling,

and primary production.

1.2 APPLICABLE STANDARDS AND GUIDELINES

The ADB SPS requires that ecosystem services are assessed when determining

whether a project triggers the requirements for Critical Habitat. The definition

of Critical Habitat under the SPS (Clause 151 of the ADB Source Book)

specifically references ecosystem services as a component of Critical Habitat.

Clause 183 of the ADB Source Book also identifies ecosystem services as a

component necessary for assessment in relation to sustainable natural

resource management (ADB 2012).

The International Finance Corporation’s (IFC) performance standards require projects to assess and preserve the benefits from ecosystem services. The IFC

also requires that the environmental and social risks and impacts

identification process considers a project’s dependence on ecosystem services. A fundamental component is to apply the mitigation hierarchy to determine

measures to limit impacts on ecosystem services.

ERM has utilized the WRI Guidelines: Weaving Ecosystem Service into Impact

Assessment to guide the approach used to assess ecosystem services in relation

to the project. The ecosystem services review was undertaken following a

five-stage approach (WRI 2014):

Screening assessment to Identify Ecosystem Services that may occur within

the study area;

Data Collection and prioritization for ‘screened in’ Ecosystem Services;

Scoping; to refine the list of ecosystem services based on those identify in

the study area and potentially impacted by the project;

Prioritization to identify Ecosystem services importance to beneficiaries;

and;

Impact Assessment to identify the impacts to ecosystem services and their

human beneficiaries as a result of the project

2 ECOSYSTEM SERVICES SCREENING ASSESSMENT

2.1 APPROACH

An ecosystem services screening assessment was undertaken to determine the

likely ecosystem service values that could be potentially important to affected

communities.

The scoping exercise was undertaken in order to refine the list of Ecosystem

Services that:

Potential Beneficiaries: Known and potential beneficiaries for a service

were identified and where possible identifying people at the local, national,

and / or global level;

Sources of Impact: Potential sources of impact were considered based on

the Minutes of Meeting during Public Consultation on AMDAL conducted

by Supreme Energy Muara Laboh;

Project Dependence: IFC PS-6 requires that the Ecosystem Services

assessment take into consideration any services that the Project may rely

upon during construction, operation and/or decommissioning. Therefore

all services for which there is a potential project dependency were scoped

into the prioritisation stage.

The goal of the scoping exercise was to identify a list of Ecosystem Services to

be assessed during through the surveys.

2.2 RESULTS

This assessment was done using existing sources of data, including

information gleaned during the scoping visit. This visit was held in October

2017 and consisted of initial interviews with Supreme Energy representatives

in Muara Laboh, West Sumatra site location as well as with local community

representatives in the following sub-villages: Blok Nol, Pekonina, Kampung

Baru, Taratak Tinggi, Pinang Awan, Ampalu, Pinang Sinawa, Koto Baru, and

Tarak Bukareh.

The results of the scoping assessment are contained in Table 2-1.

Table 2-1 Ecosystem Services Screening Assessment

Ecosystem Service Type Description, Examples Current Known Ecosystem Services Screened

in?

Provisioning Services

Food: wild-caught fish and

shellfish & aquaculture

Fish caught for subsistence or

commercial sale; Fish, shellfish,

and/or plants that are bred and

reared in ponds, enclosures, and

other forms of fresh- or salt-water

confinement for harvesting

Local villagers do not catch fishes in local rivers/creeks (Bangko Putih, Bangko Hitam, Bangko Keruk,

Batang Marite, Batang Bangko Kete' and Batang Bangko) on regular basis. Local villagers do fishing as an

entertaining activities (not main source of livelihood/fulfill protein needs). However, only few villagers catch

fishes in Batang Bangko Kete' (in Pinang Awan Sub-village) where local fishes caught are gariang

(neolissochillus thienemanni sumatranus) and kulari (gobiidae glossogobius biocellatus). To fulfill protein

needs from fishes, villagers bought fishes in the market sold by seller who live outside Muara Laboh and

Price of fish bought from local market is ranging from Rp. 35,000 to Rp. 40,000 per kilogram. In addition to

that, some villagers have fishponds in their house yards (small quantity of production) for their own

consumption or sell to other neighbors when needed. Types of fish that are in the fish pond (local name):

Nila, mujair, gold fish, and patin. Eel is also caught in muddy paddy field that has been harvested. Fish seeds

are supplied from outside Muara Laboh (Maninjau Lake).

Therefore, the project is unlikely to have a significant impact on this service.

No

Food: wild meat Animals hunted for primarily for

food (recreational hunting

covered under cultural services)

Villagers do not catch wild animals (such as wild boar, deer, etc.) in the forest. For protein needs, villagers

consume meats from cow, and chicken by buying them in the local market. There are few villagers who keep

small quantity of cows, and chicken. In some villages/sub-villages, villagers hunt for wild boars as they

sometimes enter the crops field/plantation and destroy it and wild boar is considered pest for local farmers

as they disturb plantation. Types of crops which are favor to wild boars are red union, coffee and others.

Evidence suggests that there is no currently hunting by local people for wild meat within the Project Area

and AoI.

No

Food: cultivated crops Annual and permanent crops

grown for subsistence use and

commercial sale

Major livelihood of local villagers is from paddy/rice field and coffee plantation. In addition to that, after

paddy harvesting, local villagers plant vegetables such red union and chili. Type of agriculture is permanent

plot as each villager has various size of land ranging from 0.25 hectare to 1 hectare. Rice is partially for own

consumption and other sell to the local traditional market. For coffee, there are few middle men who come

from outside sub-village and help villagers to sell outside sub-village or districts. Additionally, there is no

forest conversion for new agricultural areas because local villagers have permanent plots utilizing their lands

into two: rice-field and crops/plantation. Rice-field is reutilized after it is harvesting

Evidence suggests that cultivated crops occur within the Project Area and AoI. There is potential for impacts

to cultivated crops from air emissions.

Yes

Food: herbs and plants Herbs and plants collected for

food by local people

Herbs and plant are planted in the local villagers' house yard and in between other crops such as ginger,

turmeric, galangal, lemongrass, etc. Herbs are used for cooking ingredient. Local villagers have less interest

in making traditional herbs drink (example ginger drink) in their daily consumption, however, if they need

to keep body health stamina, local villagers made herbs drink from ginger and lemongrass.

Evidence suggests that herbs and plants are planted in villagers’ farm or house yard.

No


2-3


in?

Livestock farming Sedentary and nomadic livestock

farming

There are no livestock farming because livestock farming is not primary livelihood of local villagers. There

are only very few quantity of cows and chicken that are available. Cows or chicken are sold to their

neighbors or people from outside sub-village when religious festive is commenced.

Evidence suggests that local people do not undertake livestock farming within the Project Area and AoI.

No

Biomass fuel Wood, dung and plant matter

collected for charcoal, fuel

Local villagers do not utilize biomass fuel for their daily cooking fuel from their livestock. Cows and chicken

are in very small quantity. Cow and chicken dung are utilized for crops fertilizer.

Evidence suggests that there is no collection of wood, dung and plant matter for the production of charcoal

and fuel.

No

Timber and wood

products

Wood collected for local use or for

sale as timber, wood pulp and

paper

Local villagers collect timber and wood from their own crops field/ plantation where they plant suren (toona

sureni merr), medang (cinnamomum spp.) trees for building houses. Local villagers are not authorized to enter

nearby forest (National Park of Kerinci Seblat) for collecting timber and wood product as it is violation of the

law (Forestry). Suren and medang trees to be sold to other villagers/neighbors who need woods for building

houses. Illegal logging has long been forbidden by relevant government official (Forestry) since 1980 when

Ministry of Forestry and local government official forbid anyone to enter the forest especially TNKS for

timber/wood and non-timber/wood products. Local villagers understand and abide by the rules of

prohibition to enter the forest to pick up timber/wood. Local villagers do not want to get trouble with

forestry law/regulation as the sanction is imprisonment.

Evidence suggests that wood is harvested from villagers’ own plantation or farm.

No

Non- Timber Forest

Products (NTFP)

Non-timber products collected

from the forest. For example, cane,

palm, straw, cotton, hemp, twine

and rope, natural rubber

Local villagers do not collect or gather non-timber forest product such as wild honey. Wild honey is gathered

or collected from bees that made their nests in trees like durian, rubber and other trees in plantation/crops

field. The honey is sold to local villagers who need it. The price of honey is valued Rp. 150,000 per bottle (1

liter).

Evidence suggests that NTFP is harvested from villagers’ own trees planted in their farm/plantation.

No

Regulating services

Freshwater Freshwater for bathing, drinking,

irrigation, laundry, household and

industrial use

Freshwater is utilized by local villagers for various purposes such as rice field irrigation, development of

micro-hydro power and hygiene activities. Through development of micro-hydro power, local villagers use it

for their electricity as the PLN network is not available. Local villagers also manage irrigation system based

on collective mutual agreement among rice field owners. Local villagers informed that spring water is always

ready to be used regardless of wet or dry season. So far, local villagers have not yet experienced any

insufficient quantity of spring water for their daily use (hygiene, cooking and drinking).

Evidence suggests that freshwater is used by local people from within the Project Area and AoI. The project

may restrict or impact this activity.

Yes


2-4


in?

Biochemical, natural

medicines,

pharmaceuticals

Natural medicines, biocides, food

additives, pharmaceuticals and

other biological material for

commercial or domestic use. For

example, pelts, carved or

decorative animal products, live

animal trade

Local villagers do not collect or gather any natural medicines from the forest. Local villagers go to doctor or

drugstore or village health center if they are sick. For light treatment such as to reduce fever and sore throat,

local villagers use medicinal plants called "akar lundang" that grow wildly in their house yards or crops

field/plantation.

Evidence suggests that there is no use of natural medicines biocides, food additives, pharmaceuticals and

other biological material for commercial or domestic use.

No

Genes and genetic information

mammals pollinate certain flora species, including some agricultural crops in the vicinity.

No

Cultural Services

Spiritual, religious or

cultural value

Natural spaces or species with

spiritual, cultural or religious

importance

There are no forest or river resources for spiritual and religious values. Local villagers are embracing the

religion of Islam. Therefore, they do not utilize any forest or river resources for spiritual and religious values.

Few local villagers still use a incense (styrax benzoin) for cultural or customary events. Such incense is used

as a companion of prayers to start the paddy field planting season. Raw materials of incense are obtained

from local traditional market (in Muara Laboh). However, local villagers do not know where the seller

obtains raw materials of incense. Local villagers in project area do not plant incense in their crops field or

plantation.

Evidence suggests that the Project area of AoI is not considered as important natural spaces or species with

spiritual, cultural or religious importance.

No

3 ECOSYSTEM SERVICE DATA COLLECTION AND PRIORITIZATION

Community interviews were conducted on ecosystem services at the SEML

site location in Muara Laboh in October 2017. The methods used and results

identified are outlined below.

The following summary of the methodology and results during ecosystem

services assessment are outlined below.

3.1 COMMUNITY SURVEYS

ERM undertook the following consultation as part of ecosystem services

assessment:

Consultation meetings with internal SEML representatives (environment,

social and management).

Consultation with twenty (20) local village representatives living in close

proximity to SEML site location from selected communities (9 sub-villages);

and

Household survey questionnaires were used to gather data from the

communities around SEML to solicit their opinions on both the positive

and negative aspects of the Project development. The data is relevant to

understanding current socio-economic conditions in the Area of Influence

of the Project, historical impacts associated with SEML activities as well as

potential issues associated with the on-going activities of the Project.

The topics addressed in the household surveys included:

Basic household information (Individual); and

Socio-economic system survey as a quantitative assessment of the level of

reliance on natural resources by affected communities and the linkage

between the subsistence economy and the livelihoods of affected

communities.

Prior to conducting household surveys, an introductory meeting was

convened in the host community to introduce the purpose of the consultation.

3.2 DATA COLLECTION

Data was collected through community meetings, household surveys and face

to face discussions with stakeholders. Community meetings were arranged

by SEML representatives in collaboration with the village leaders and other

village representatives. The meetings provided an opportunity to gather

feedback on SEML activities.

A total of twenty (20) village representatives had discussions on their socio-

economic conditions across nine (9) sub-villages with particular focus on the

livelihoods of women and farmers. The details the surveys conducted are

shown in Table 3-1.

In addition to conducting face-to-face interviews with local villagers, ERM

also conducted field observations. The field observations include the presence

of Pamsimas (Indonesian Government program in relation to clean water

access and sanitation for local communities), rivers and site visits to SEML

project activities.

The questionnaire used to collect data on ecosystem services is shown in Table

3-2. Data was collected on screened in ecosystem services relevant to the

community. Information was collated on:

4 ECOSYSTEM SERVICES PRIORITISATION

4.1 APPROACH

The WRI guidelines and IFC PS6 requires that priority ecosystem services are

identified, and impacts to those services are assessed (IFC 2012). The

prioritization process is aimed at identifying those services for which Project

impacts would be most likely to result in adverse impacts on project affected

communities and other beneficiaries. Using the information collected through

the baseline data collection and stakeholder engagement processes, Ecosystem

Services were prioritized according to a priority matrix ranking two criteria:

Importance of the ecosystem service to the beneficiary which considers the

intensity of use, degree of dependence and the importance expressed by the

project affected communities; and

Irreplaceability of the ecosystem service, which refers to the availability of

alternatives, the accessibility, cost and appetite for those alternatives as

discussed with the beneficiary.

4.2 RESULTS

After compiling baseline information on the importance and irreplaceability of

each service, these ratings were combined to assign a priority rating to the

service grading from Low to Major as shown in the ecosystem service

prioritization matrix in Table 4-1.

Ecosystem services identified as High priority or Major priority were

considered Priority Ecosystem Services. The weight given to each of these

components varied slightly depending upon the service, but stakeholder

values were given precedence over other criteria where the rating was not

clear.

In addition to the above, according to the IFC definition of priority ecosystem

services, all services for which project dependencies are identified are

considered priority services. The importance and irreplaceability of services

relied upon by the Project was assessed through the same prioritization

process outlined above, with the Project filling the role of the beneficiary.

In addition to the prioritization exercise, the baseline data collection process

provided the opportunity to collect information on the status, trends and

sustainability of resource use as they pertain to the habitats and species that

support Ecosystem Services. This information was gathered through

secondary sources and field studies by the environment team and where

appropriate through engagement with local stakeholders. This information is

important for the assessment of impacts on Ecosystem Services and therefore

on local people as the final receptors of these changes.


4-2

Table 4-2 outlines the beneficiaries, potential sources of impact and project

dependence for each service, and whether the service was scoped into or out

of the Ecosystem Services assessment.

This section provides an assessment of the potential Project impact to

The following priority ecosystem services shown in Error! Reference source

ot found. have been identified and will be assessed against the impact

assessment procedures.

Table 4-3 Priority ecosystem services

Priority Ecosystem

Service

Description

Freshwater Evidence suggests that freshwater is used by local people from within

the Project Area and AoI for irrigation system and micro-hydro

development. The project may restrict or impact this activity. Impacts

from the project activities may likely impact downstream due to

utilization of river water, especially during the dry season due to

decrease of water flows.

Erosion regulation Evidence suggests that Muara Laboh Project area of AoI has regulating

erosion on slopes and riparian areas in the vicinity. The careful efforts in

erosion control can provide stability to the slopes to reduce the chance of

land slips and erosion. The land clearing and other related project

activities might potentially change the river sedimentation and

occurrence of erosion.

5 IMPACT ASSESSMENT FOR PRIORITY ECOSYSTEM SERVICES

5.1 APPROACH

In a mitigation context, rigorous functional ecosystem services (ecosystem

services) impact assessments focus not only on how supply is disrupted but

also on how the delivery of services will be impacted over the lifetime of the

project, and how much those changes are likely to matter to people (value). At

the mitigation stage, ERM identifies options through the mitigation hierarchy

to enhance or at least maintain: (1) the well-being affected beneficiaries derive

from ecosystem services and (2) the performance the project derives from

ecosystem services at acceptable levels.

Based on World Research Institute (WRI) publication titled “Weaving Ecosystem Services into Impact Assessment”, ecosystem service mitigation measures inform project design and operations and are incorporated into the

environmental and social management plans. Once ecosystem service-specific

mitigation measures are identified, ensure there are no conflicts between these

mitigation measures and the ones identified independently by the

environmental and social practitioners.

5.2 PROPOSED MITIGATIONS

For freshwater, water-related ecosystem services that depend on catchment-

scale hydrologic functions should be mitigated within the same catchment

(watershed) to provide the same benefits to the same people. The watershed is

determined by the area that supports biophysical service production, and

allows beneficiaries both physical and institutional access to the service. Water

quality and quantity protection measures should therefore be applied within

the watershed where the SEML project is located.

On erosion regulation, geothermal development may be accomplished with

minimal mass soil movement problems, if development sites and roads are

located and constructed appropriately.

The following Table 5-1 indicates the mitigation actions proposed for the

SEML project to reduce impacts on the priority ecosystem services.

It should be noted that these mitigations are currently being implemented by

SEML and outlined in the BAP (v10). No additional mitigations are therefore

necessary for the Project to implement to reduce the impacts to ecosystem

services.

Freshwater use impacts can be reduced by utilizing dry cooling or by using non-

freshwater sources as a cooling medium. A non-freshwater sources such as utilization of

groundwater;

Freshwater use impacts can be reduced by utilizing groundwater source for washing and

bathroom facilities

Erosion Regulation Local villagers Sediment carried in waters drained

from roads and also soil

sedimentation** includes damage

to provisioning value streams or

rivers.

Road and train construction will not block drainage systems or water courses. Culverts or

other suitable crossings will be installed in drainages, and roads will be drained or water

barred as necessary to prevent erosion;

All roads planned for permanent or long-term use will be adequately gravelled or paved;

Roads, well pads, building and associated structured will be located and designed to

require minimum earth movement for their construction;

All disturbed areas will be seeded, mulched, and fertilized for adequate protection from

rain and run-off. Where feasible, native vegetation will be included in the prescription to

restore the natural setting and to take advantage of normal ecological relationships;

Adequate erosion control and drainage measures will be required on disturbed sites to

minimize soil movement and sedimentation of water courses.

Notes:

*water utilization by the SEML project in smaller quantities, water may be needed on a temporary basis for well field development for things such as dust suppression, drilling fluid, and reservoir stimulation. Small

amounts of water may also be needed for washing and bathroom facilities for the power plant. In some cases, most geothermal plants can use either geothermal fluid or freshwater for cooling.

**soil erosion impacts can be expected from clearing and earth movement activities associated with construction of building, well sites, pipelines, transmission lines, and roads.

December 2017. The survey collected two types of fresh water fauna

biodiversity, Fish and Macroinverterbrates. Total seven streams were surveyed in

SEML. There are five species of Fish include in three Family reported. There are two

species of Balitoridae, two species of Cyprinidae and one species of Cichlidae. The

dominan species were Homaloptera cf. ripleyi,

Homalopterula gymnogaster which is an endemic Sumatra and Barbodes banksi.

Tor douronensis obtained only at one stream. In addition, there was

Oreochromis niloticus collected which is an introduced species that are purposeful

stocked into the pond around the stream. Reffering to IUCN Red List, they all are in

NE (Not Evaluated) status except H. gymnogaster under Indonesia Protected.

Diversity index for fish in the SEML area classified as low diversity.

The presence of Macroinverterbrates genera on each stream is varied. Genera

found in all streams are the Centroptilum, Nemura, Hydropsyche, but Simulium are

not found in one stream. The predominant macroinvertebrate genera are: Simulium,

Centroptilum, Pseudocloeon, Nemura, Orthocladinae, Hydropsyche, Neophylax and

Melanoides. One genus of crab Parathelphusa maculata founded in SERD and

SEML. That species recorded as Least Concern (LC) in the IUCN Red List.

The analysis of macroinvertebrates data showed that the stream ecosystem in

the SEML area is relatively undisturbed and the quality is classified as of clean

water. This indicated by the number of macroinvertebrates genera of each stream

which is relatively high ( 19-27 genera) with the number of individuals range from

95 to 206 individuals, and the genera diversity index is moderate (2,00 -2, 59).

I. INTRODUCTION

Biodiversity refers to the term for the degree of nature’s variety or variation within

the natural system, both in number and frequency. The manifestation of biodiversity

are the biological resources (genes, species, organisms, ecosystems) and ecological

processes of which they are part (Mutia, 2009). The variety of species are measured

in term of Species Richness and Species Abundance. Species Richness is the total

count/number of species in a defined area. While Species Abundance is refers to the

relative numbers among species (Rawat & Agarwal, 2015).

In the level of species, the same species often show differences in phenotypic

characters and may also include genetic characteristics if living under different

ecological conditions (Moyle & Cech, 2000). Keeley, Parkinson & Taylor (2005)

suggest that the differences in characters that appear in response to habitat conditions

will increase the variation and differentiation that can lead to speciation, especially in

conditions of disconnected of gene flow between populations. There for in the future,

it also important to monitor their genetic diversity.

Human activity for the purpose of harvesting natural resources for industry

production and urbanization is often destroyed the natural habitats. Clearing forest

areas, mining, logging, urban sprawl, construction of highways are some examples of

habitat destruction and fragmentation (Agarwal et al, 2014 and Rawat & Agarwal,

2015).

PT SEML are Joint Ventures of Supreme Energy, Engie and Marubeni to

develop a geothermal power plant with an installed capacity of 80MW. The SEML

project is located in Muara Labuh in Solok Selatan Regency, West Sumatra Province.

The projects consist of wellpads and interconnecting pipelines to supply steam to a

power generator. A switch yard and transmission line network is also associated with

the Project. Geologically, areas are located in the Barisan Mountains Zone or exactly

in the active fault zone of the Great Sumatra Fault (GSF). Geomorphology, PT SEML

is located along the Sumatra fault system. Two geothermal sources extend along 50

km of the Sumatra fault zone, namely North Muara Labuh and South Muara Labuh.

5

Both geothermal sources have different geothermal and recharge sources, although

hydrologically interconnected with each other.

The presence of geothermal power plant project may alters stream conditions,

reduces connectivity, and blocks access to upstream areas with high quality habitat,

abundant prey, and fewer predators. That area is often blamed for population declines

of migratory fishes. According to Chaudhuri (2005), the availability of data and

specific detailed information about the biodiversity of fish in various types of aquatic

ecosystems is indispensable as a basis for freshwater fisheries habitat management on

an ongoing basis. In other to anticipate losing diversity of fish fauna in the area to be

developed in the construction of Geothermal Power Plant in SEML zones, research is

conducted through a rapid assessment activities. The aim of the research is to collect,

to record and to study diversity of fish species present in the streams in that area, as a

baseline data within the project zone which can to be useful for aquatic resources

management of this area in the future.

Aquatic macroinvertebrates has a role as indicators of water quality. Different

types of macro invertebrates tolerate different stream conditions and levels of

pollution. Depending on the types of macro invertebrates found in a stream,

predictions about water quality can be made. Aquatic macro invertebrates are also an

important part of aquatic and terrestrial food chains. They graze on algae and break

down leaves and sticks that fall into the water. They are also an important food source

for fish. Macroinvertebrates samples collection able to estimate water conditions as

ecologically. Population estimation, diversity, composition and community structure

of macro invertebrates able to show the description of the environment and carrying

capacity in that location. (Michael, 1984; Wallace and Webster, 1996).

In connection with the construction and development of geothermal energy

resources in Muara Labuh, an aquatic biodiversity survey has been conducted. The

purpose of these surveys is to obtain further information on freshwater aquatic

biodiversity values at the area and to improve understanding of the conditions of

these areas. Specifically, the purpose of this survey are to determine the presence of

species of conservation significance (CR, EN and VU on the IUCN Red List of

6

Threatened Species; Indonesian Protected Species, migratory and/or

endemic/restricted range species) within the Project Area.

II. METHODOLOGY

Sampling method and Study area:

The survey collected two types of fresh water fauna, Fish and Macroinverterbrata in a

total of eight sites in Supreme Energy Muara Labuh area. The surveyed focused to

the stream system. The sampling was done during the wet season on 6th

December

until 8th

December 2017.

II.1. Sampling method of Fish:

The study used survey and directly collection methods, following standard procedure

according to Cailliet et al. (1986) using fish net and backpack electrofishing gear (12

Volt). Sampling of every available location was done in one-two hours. The

characteristics of sample obtained such as body and fins color that may be lost or

changed after death were photographed. Then, samples will preserved with

formaldehyde 4-10 % in plastic box during in the field and then wrap in gauze

bandage when transported and taken to the laboratory. In the laboratory, all specimen

preserved later in 70% ethanol. Taxonomic studies, count and measurement are based

on Hubb and Lagler (1947). Measurement were made by using Vernier caliper.

Classification and identification follow those texts written by (Weber & Beaufort,

(1916), Roberts (1989), Kottelat et al. (1993), Kottelat & Whitten (1996), Kottelat

(2013). All specimens are deposited in Andalas University Museum. Upon each

sampling location, the composition of riparian vegetation, stream substrate, type of

water level, current (using a buoy), and temperature were recorded. Local weather,

date, time of day, location, stream channel conditions also recorded.

II.2. Sampling method of Aquatic Macroinvertebrates

7

The sampling of Aquatic macroinvertebrate was done in seven streams around the

SERD Project. The sample was collected using Surber net Sampler (with quadrat

frame 30 cm x 30 cm in size). The sampling methods refer to the modified RBA

(Rapid Biodiversity Assessment) protocol. The sampling area in each stream was

determined along 100 m which represents the characteristics of the stream. The

samples collected from the productive area (the area most likely inhabited by

macroinvertebrates) such as riffle, pool, run, leaf pack, stream margin with vegetation

within the 100 m reach of the stream. Sampling began at the downstream and

proceeded to the upstream. In each stream collected tree sample with Surber net on

the rocky substrate is approximately faunal diversity in the area. The Surber net place

on the bottom of the stream with the mouth facing upstream, 20-30 cm depth. The

quadrat frame is held with one foot. All the stones in the square are pick up and

remove from the bucket. The remaining substrate in the square is disturbed by garden

trowel so that organisms will be dislodged and washed into the net. The stone

brushed in the bucket is filled with the sufficient water to cover stone by using a stiff

bristle brush to release the organisms. Macroinvertebrates were filtered through 250-

micron mesh sieve. The material leaf in the filter removed to the jar and water added

sufficiently. Preserved with 40% formalin arranged to the concentration of the

solution in the sample bottle to 4%. Hand collection is also done with the aim that the

animal not caught with the net will be found in this way. Five stones which are

biggish, flat and rough surface selected. The animals attached to the stone are taken

with tweezers or removed with a wire brush. The samples were also collected from

the leaf pack and stream margin with vegetation by the same sampler. The debris

rinsed and inspected, then filtered through the same screen. The sample place into the

jar. Identification of macroinvertebrates was done in Animal Ecology Laboratory of

Biology Department of FMIPA Andalas University using dissecting microscope 4 x

10 to 6 x 10 magnification and related reference book. Identification was carried out

to the genus level based on Quigley (1977), Van Benthem Jutting (1956), Edmunds,

Jessen, and Berner (1976), Pennak (1978), Merrit and Cummins (1984), Kawai

(1985), Pescador, Ramussen and Harris (2002), etc.

III.2. Fish and Macroinvertebrate diversity

III.2.1. Fish diversity

Survey that has been done around PT Supreme Energy Muara Labuh (SEML)

documented 5 Species, include in three Family consist of Balitoridae (two species),

Cyprinidae (two species) and Cichlidae (one species). The species found dominantly

were Homalopterula gymnogaster , Homaloptera cf. ripleyi, and Barbodes banksi.

In addition, there was Oreochromis niloticus collected (Table 2, Table 3 and Figure

4). All the species collected have a NE (Not Evaluated) status in IUCN Red List and

only one is Indonesia Government protected as a endemic island species, which is

H. gymnogaster .

13

According to the villagers there are several Fish in Liki Stream like Hampala

macrolepidota, Barbodes, Tor douronensis, Glyptothorax, Homalopterula, Channa

and Hemibgrus. Unfortunately, in our rapid assessment we could not find all of them.

Barbodes banksi firstly known as a synonym of Puntius binotatus, which

distributed widely in Southeast Asia. They live in lowlands to highlands and

http://www.fishbase.se/ComNames/CommonNameSummary.php?autoctr=52998

14

categories as not migrated species (Roberts, 1989) and Rainboth (1996). In the IUCN

Red List, this species has been reported as Barbodes binotatus (Kottelat, 2013) and

Jenkins et al. (2015). According to Kottelat (2013), P. banksi assigns as B. banksi

with a synonym of P. binotatus banksi (B. binotatus banksi). In the diversity study,

Roesma (2011) has been reported that there are three groups of P. binotatus in West

Sumatra where Kottelat (pers.com) proposes to record as P. cf1.binotatus, P.

cf2.binotatus, and P. cf3.binotatus according to its geographic distribution. Vitri,

Roesma and Syaifullah (2012) showed that there are the variation of the

morphological characters between West Sumatra samples at different altitudinal. The

latest phylogenetic study using CO1 gen, Roesma et al. (2017 in press) found that

three group of P. cf. binotatus from West Sumatra were strongly supported as

Barbodes banksi with genetic variation ranging from 0 to 8.3% which is also consist

of three groups. The sequent divergent between B. banksi and P. binotatus ranging

from 11.6% to 12.6%. Based on the above information and geographic position, we

are suggested that the spotted barb in SEML area is a B. banksi. In this survey, B.

banksi found in three sites (Table 3.) with the frequency of attendance is 37.5 (Figure

4). It is possible that the population of SERD area will show the variations.

According to Moyle & Cech, (2000), in the level of species, the same species often

show differences in phenotypic characters and may also include genetic

characteristics if living under different ecological conditions. Keeley, Parkinson &

Taylor (2005) suggest that the differences in characters that appear in response to

habitat conditions will increase the variation and differentiation that can lead to

speciation, especially in conditions of disconnected of gene flow between

populations. There for in the future, it also important to monitor their genetic

diversity.

In this survey, apart from Barbodes, species exhibiting high numbers of

individuals as well as frequencies of attendance were Homalopterula gymnogaster

and Homaloptera ripleyi (Table 2, Table 3 and Figure 2). According to Silas (1953),

the genus Homalopterula is a synonym of the genus Homaloptera due to

morphological variations in the caudal and the presence or absence of scales on the

15

ventral surface of the abdomen. H.gymnogaster is an endemic island species of

Sumatra and listed as Indonesian protected fish under Government Regulation (PP.

Number7,1999). Roesma (2011) has collected H. gymnogaster from several streams

and rivers spread in West Sumatra. The phylogenetic studies are being conducted at

this time. Furthermore, Ott (2009) states that Homalopterula is a subgenus of

Homaloptera and reaffirmed by Kottelat (2012) that the genus Homalopterula is a

synonym of the genus Homaloptera.

In this survey another Homaloptera also found which is characteristics very

similar to H.ripleyi (Sumatran endemic species), we name it as H.cf. ripleyi because

of more study should be done to make it accountable. H.ripleyi is only known by the

holotype from Northen Sumatra which is deposited in the Natural History Museum in

Philadelphia. H.ripleyi originally described by Fowler (1940), and has been re-

described by Ott (2009). From the Table 2, it is known that H.gymnogaster and H.cf.

ripleyi can be found in the same sites, meaning they can co-exist and need the same

habitat conditions. Thus, it is also likely to be found in other waters where

H.gymnogaster is.

An individual Oreochromis niloticus was also caught and recorded in this

study. The fish is found at the location of SEML 7, which is a small tributary. Near

the creek was created a pond for water reservoir. O. niloticus stocked into it for food

and games.

Figure 4 shows the frequency attendance of fishes in SEML (Supreme Energy Muara

labuh). The highest value was Homaloptera cf. ripleyi (F: 85,71), followed by

Homaloptera gymnogaster (F:71,43), Barbodes banksi (57,14), Oreochromis

niloticus (F:14,29), and Tor douronensis (F:14,29).

Figure 5. Shannon-Wiener species diversity in the SEML

The higher diversity index was in SEML-5 (H’: 1,23), followed by SEML-6

(H’:1,08) and categorized as fair diversity. SEML-7 and SEML-2 (0,81), SEML-3

(H’:0,66) and , SEML-1 (H’:0,48) were categorized as low diversity. There is no

categorized of SEML-4 caused none of fish caught from the site (Figure 5). . In

general, diversity index for SERD area classified as low diversity of fishes. This

condition can be understood because of the sites surveyed are around 1000-1500 m

asl with the water temperature ranging from 150C-24

0C. Besides that conditions, as

is typical of the river upstream, many rapids on the stream also inhibit the migration

of fish. The frequent occurrence of landslides entering water bodies also leads the

habitat and the component of the population.

As there seems to to be a considerable amount of variation in the markings between

populations, it also mean that banksi and binotatus represent 2 extreme color forms of

a single species (Kottelat and Lim, 1995). This species has 90-110 mm in maximum

standard length (seriouslyfish, 2017).


Found in a variety of small streams in lowland and foothills, usually with clear water

(Kottelat and Widjanarti, 2005).

Distribution : Malaysia, Singapore and Indonesia

Figure 9: Oreochromis niloticus (Linnaeus, 1758)

Description:

O. niloticus has 15-18 dorsal spines, 11-13 dorsal soft rays, 3 anal spines, 9-11 anal

soft rays and 30-32 vetebrae. Maximum standard length is 60 cm, but usually smaller

(around 35 cm). Male fish develop pointed dorsal and anal fins while the females are

rounded. Jaws of mature male not greadtly enlarged (29-37% of head length).The

presence of regular vertical stripes throughout depth of caudal fin can be the most

distinguishing characteristic (Fishbase, 2017).

Habitat and ecology:

It is an adaptable species that is found in a wide range of habitats, including streams,

streams, ponds, lakes and coastal plains. It occurs in both fresh and brackish waters

and usually inhabits shallow areas. Some vegetable matter should be included in its

diet. This species will eat most food offered.

Distribution :

O. niloticus has a very wide natural range and is native to (in alphabetical order)

Burkina Faso, Cameroon, Chad, Egypt, Ethiopia, Gambia, Ghana, Guinea, Israel,

Ivory Coast, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone, Sudan, Togo and

Uganda. It has also been introduced as a food fish in over 70 other countries and

escaped or released populations now exist in many of these (Seriouslyfish, 2017).

Several countries report adverse ecological impact after introduction.

III.3.1. Macroinvertebrate Diversity in SEML area Project

Survey that has been done at six streams around PT Supreme Energy Muara Labuh

(SEML) documented 69 genera, 907 individuals include in seven Class (Arachnida,

Malacostraca, Insecta, Hirudinea, Oligochaeta, Gastropoda dan Turbellaria) and 15

orders (Aranea, Decapoda, Coleoptera, Diptera, Ephemeroptera, Hemiptera,

Hymenoptera, Lepidoptera, Odonata, Plecoptera, Trichoptera, Pharyngobdellida,

Haplotaxida, Mesogastropoda dan Trilacdida). The entire genera found in this study

is shown in Table 4. All of the macroinvertebrate genera can not be determined it’s

status as there is no reference to the determination of animal status. These genera not

found in IUCN Red List, CITES, PP no.7 / 1999 and no. 8/1999, except for one genus

of Malacostraca that is Parathelphusa maculate (Fam. Gecarcinucidae) (Figure 9).

These crabs included in the IUCN Red List of Threatened Species as Least Concern

(LC).

Table 5 present the composition of macroinvertebrate communities in all

streams. Total number of genera and number of individuals dominated by Insecta (57

genera and 869 individuals around 98.69% of individuals total). This is because

Insecta is able to live in various habitats under different conditions. Generally the

stream community consists mainly of pre-adult Insects (William and Felmate, 1992).

This is due to its ability to survive in flowing waters although fast current velocity

because it has a flat-dorsoventral body, strong claw and has a case attached to the

bottom surface of the rock, so it can maintain its position despite rapid current. The

26

base substrate in this stream is generally rocky with moderate to fast currents

velocity.

Other classes such as Arachnida, Malacostraca, Hirudinea, Oligochaeta,

Gastrpoda and Turbellaria found 1-4 genera with small individuals number range

from 1-21 individuals. Arachnids are found around riverbank plants and Malacostraca

also found rivebank on muddy substrates. Usually habitat of Oligochaeta on a muddy

substrate with a high organic content, therefore it is little found in streams that have

rocky base substrates, such as observed stream.

Gastropods were found only in SEML 2 (Bangko Karuah stream) of 4 genera which

is dominated by Melanoides. On the edge of the stream there are rice fields, we

estimated that the gastropods found in this stream come from the fields enter with the

flow of water into the stream. The stream conditions suitable for gastropod life such

as algae-covered the stone in the bottom provide a food source for the organism so

that it can survived in the Bangko Karuah stream. Gastropods are also found in the

pool that found in this streams. In this puddle also found 3 genera of worms

(Oligochaeta) which is a characteristic genera in calm waters with muddy substrate.

The dominance of Insects in this stream is due to its ability to maintaining the current.

Insects’ larva generally has attachment devices including silk and other sticky

secretion, hooks, suckers and cases (Allan, 1995).

Malacostraca found 1 species of crabs namely Parathelphusa maculata as

many as 3 individuals, 2 individuals found in SEML 1 (Aia Hitam Stream), 1

individual found in SEML 6 (Bangko Stream) .This crab was obtained at the

riverbank with relatively slow current velocity when collecting fish sampling using

electrofishing devices. Parathelphusa maculata belonged to the family of

Pharathelphusidae but is now classified into the Gecarcinucidae family (Klause et al.,

2008). This species prefers lowland stream and tolerant of muddy water. This animals

have a hight tolerance of low oxygen condition. It commons under rock, logs,

vegetation, debris but also dig deep burrow on the banks of the stream. The burrow is

always open into the water. Normally adult females live in burrows, but their

juveniles can be found in open water (Klause et al, 2008).

locations. The larger number of species in SERD5 (Liki) was caused by the presence

of more Hemiptera in the riverbanks upstream of the dam in this stream.

The frequency of attendance can describe the distribution of organisms in

their habitats. Frequency of attendance of macroinvertebrates based on order in

SEML area can be seen in Figure 12. Diptera, Ephemeroptera, Hemiptera, Plecoptera

and Trichoptera have the highest attendance frequency (F = 100%) followed by

Coleoptera and Odonata (F = 83.33), Hmenopteraa (F = 66.67%), Tricladida (F =

50.00 % ), Lepidoptera (33.33 %) and the lowest are Aranea, Pharyngobdellida,

Haplotaxida dan Gastropoda (F = 16.67). This data showed that Diptera,

Ephemeroptera, Hemiptera, Plecoptera and Trichoptera are always found throughout

the stream but Aranea, Pharyngobdellida, Haplotaxida dan Gastropoda were the least

rare order. The presence of EPT (Ephemeroptera, Plecoptera and Trichoptera) in the

streams may indicated that streams have a rocky substrate and rapid current and clean

water quality. Ephemeroptera and Plecoptera were highly susceptible to changes in

dissolved oxygen content, They are requiring dissolved oxygen 6-7 mg / l, while

Trichoptera 5-6 mg / l. The measurement of dissolved oxygen in this survey is not

done, but usually in upstream streams which are relatively undisturbed have high

oxygen dissolved (Allan, 2001). The presence of Gastropods in Bangko Keruh

indicated stream has been lightly polluted. The pollution comes from the agricultural

land near from this stream.

In Aia Hitam stream (SEML 1) found predominant genus are Simulium (Diptera),

Centrptilum and Pseudocloeon (Ephemeroptera). Centroptilum is always present

throughout the location (F = 100%). In Bangko Karauh Stream (SEML 2) found

predominant genera are Orthocladinae 1, Orthocladinae 2, Nemoura and Melanoides.

Of these four genera only Nemoura (Plecoptera) always found in each location (F =

100%). In Muara Bangko Putiah (SEML 3) obtained the predominant genera of

Orthocladinae 1, Simulium and Hydropsyche. The last genera is always found

throughout the site. In Bangko Putiah Stream (SEML4) were dominated by

Orthocladinae 1, Simulium and Nemoura. In Liki Stream (SEML 5) found 3

predominant genera were Centroptilum , Pseudocloeon dan Neophylax. In Bangko

stream dominaned by Centroptilum, Hydropsyche and Neophylax.

The presence of predominant genera in each stream depends on the habitat's

suitability and its adaptability to the environmental conditions of the stream. Hence

there are genera that can be found throughout the stream and there are also genera its

presence is rarely or present only in certain stream. The Stream substrates in SEML

are essentially dominated by rocks and moderate to very fast current velocities. The

well-adapted genera in the stream in the SEML region were Centroptilum, Nemura

and Hydropsyche found throughout the stream and and Simulium found in five

stream. All these genera have good morphological adaptability to fast flowing water,

because they have the means to maintain themselves on such stream conditions, such

as: Centroptilum, Nemoura have a dorsoventral flat body and strong claws,

Hydropsyche has netspining, and Simulium have a circlet of hooks on posterior

proleg, wich this larvae attached to the substrate, allowing the animal to climb down

with the silk thread and re-attached on substrate (Allan, 2001).

Figure 14 presented Shannon-Wiener Diversity Index (H’) of

Macroinvertebrate in SEML range from 2.00-2.59, The diversity index of each

stream is not much different, except that SEML 4 is lower than that of other streams.

This is because the number of individuals found in this stream was less than that of

other streams. Based on genera diversity index of macroinvertebrates that the streams

in SEML are classified as moderate.

According to the criteria Lee et al., (1978) that streams with

macroinvertebrate diversity index larger than two indicate that the streams are

generally classified as clean water. The presence of EPT (Ephemeroptera, Plecoptera,

Trichoptera) in the six observed streams also show indicator of clean water quality,

especially Plecoptera usually live on rocky stream or low stream order which is

cooler and sensitive to organic pollution and low oxygen (Giller and Malmqvist

(2003).
