PLTP Lahendong ExZention (1 x 20 MW) posseses one unit steam turbin having

capacity of 20 MW. The type of steam turbin to be employed is tipe single flow

exhaust. Turbin and generator will be erected on the ground surface. Therefore, the

elevation of generating house could be maintained in lower position. The power

produced by PLTP Lahendong Extention will be joined with the Minahasa - Kotamobagu system so as to improbe the existing system liability. At present time,

the power capacity of Minahasa - Kotarnobagu system is:

Table.l.1. The Power Capacity o f Minahasa - Kotamobagu System

By the end of 2002, if there would be no disturbance to all existing power plants,

there would be actually spare power of 4.13 MW. Nevertheless, a disturbance to

one power unit (say the biggest plant), then there would be iower deficit of 15.87

MW during the peak load. This has happened a t the end of 2002, because PLTP

Lahendong I ( l x20 MW) have experience trouble and as a consequence, Minahasa -

conducted by means of cooling tower that requires about 2.900 m3 water.!%e] .. . .. . ,

water will be taken from Pangolombian like and circulating within the system during' ?;

UKL dan UPL PLTP LAHENDONC EXTENTION ( 1 X 20 MW )

i I Taking into account that water from the lake is also utilised by the local people, the

water filing process will be conducted so gradually that it will not annoy water

balance in the lake.

The amount of cooling water will be abducted periodically and therefore a periodic

addition of water is required. The amount of make up water ia about 5%-10% from

total amount. The make-up will be also taken from the lake.

b. Source of Steam

During operation of PLTP Lahendong Extention (I x 20 MW), steam from well LHD-

13 and other wells, that within one cluster with LI-ID-13, will be utilised and steam

source.

labour: 15, and non-skilled labour : 100.

Labour recruitment prosess for the non-skilled workers will prioritise the local

j workers. While the skilled worker will be recruited after consulting the Minahasa

Man Power Office. By employing the the worker market issued by the Man Power

I Office, it is expected that soeme of the skilled workers will be recruited from the

1 local people.

1 I n term of hiring foreign experts, PT PLN (Persero) will seriourly act selectively and

in accordance to the regulation. Each of the foreign expert working in the project

shall fulfil all the corresponding requirements.

In order to.avoid and minirnise accident during working hour, each worker will be

equipped with the standars savety equipment, depenting on the working risks. The

equipments include: safety shoes, helmet, safely belt, ear plug, and safety glass.

d. Waste Management System

Liquid wastes such as oil, turbin grease will be filtered in the grease trap before

directed to the collecting ponds situated outside turbin areal. The waste is then

processed in a liquid waste management installation before it directed to the water

body.

e . Power Plant Test

Power plant test or the commisioning test is the last step among construction

activities before the PLTP Lahendong Extention (1 x 20 MW) is operated. The

commisioning test will be last in three months.

2.4.3. Operation Phase

The operation phase will be started following the end of construction phase.

Following are the operational and maintenance activities of the PLTP.

a. Operation of PLTP

The steam will be supplied into the generating system at wells LHD-4 and LHD-5

through steam pipes. Prior to flowing into the turbine, the steam shall flow through

demisher that function as separator between steam and water mo~ecu~ks. The steam

will then flow into the condensator and condenses as hot water condensat. Mixture

of condensat and cooling water will be accommodated in a hot well to be further

pumped to the cooling tower. The condensat, as liquid waste, will then injected into

LHD-7 well.

Within the cooling water circulation, there will be release of water molecule and

evaporation due to blowing air in the cooling tower. Along with the process the air

will contain non condensed gas such as H2S (hidrogen sulfida) as well.

Eventhough H2S (hidrogen sulfida) will be released by means of ejector, small

amount of i t will dissolve in hot water and direct to the cooling tower. Presence of

H2S in cooling water will increase water acid::y. This will lead to the corrosive impact

to all metal components of condensor and the wall of cooling tower.

Presence of H2S (hidrogen sulfida) in cooling tower pond will decrease the acidily of

cooling water and create a yellow layer of sul?hur sediment due to reaction between

H2S and oksigen.

UKL dan UPL PLTP LAHENWNC EXTENTION L 1 X 20 MW )

The non-condensed gasses flowing into the condensator will be eliminated by means

of gas ejector. Steam flowing along with gas that absorbed from condensor will

. . condensed in inter and after cooler device. So that, there will be no steam-gas

mixture after gasejection procedure.

. , b. Maintenance of PLTP

Maintenance of PLTP includes: replace of spare-parts, maintenance of m a c l ~ i n e ~ and

electrical components, maintenance of infrastructure and facilities, and maintenance

of the main building.

Replacement of main component of the PLTP spareparts will be conducted in

accordance to its lifetime. Greasing proccss will be proceed to maintain' the

machinery. NaOH powder will be injected into the cooling water so as to avoid

malfunction of condensor and cooling tower wall due to corrosion. I

2.4.3. Post Operation Phase

Post operation phase is a phase where the PLTP Lahendong Extention (1 x 20 MW)

is not function anymorebecause its lifetime has ended and it could not be

rehabilitate. I n this phase, reclamation and land rehabilitation may be performed

according to the company policy. The next usage and management will be arranged

according to the future requirement.

3.1.2. Fisiography dan Geology

3.1.2.1. Geamorphology

Morphology of the project area is strongly related to the previous vulcano activities

Rest of volcano activities can be observed from cracter having width of yang 2 km.

there are smaller craters function as pheratic eruption during their activities. The are

Linou Lake, Tampusu Lake, and Pangolombian lake.

Morphology of the project site can be classified intothree morphology units:

mounthaneous, unduloating , and flat.

Mounthaneous morphology unit is part of Gunung Lengkowan that directed to the

Southeast. This unit is dominated by volcano brecci and andesit from Lengkoan

formation. Flat and undulating unit is where the projed situated, between undulating

and flat areas. Flat uni is part of Kasuratan-Tondangow that dominated by alluvium.

3.1.2.2. Topography I

Lahendong earth gas field is geographically situated in North of Sulawesi, in

Kabupaten Minahasa. The area is topographically as hot field situated 700 - 1200

m above sea level, while the project PLTP Lahendong Mention (1 x 20 MW) is

x 20 MW) is presented in in Figure 3-2.

Most of Lahendong earth gas field is hilly area having slope between 20' - 70" . The

rather steep area is located in Easr and South, while the sloping area dominated the

The East area is formed from Gunung Tampusu having height of 1200 meter and

Gunung Kasuratan, 975 meter. The Southeast part exists Gunung Lengkoan (910

meter) separated . .. by Kasuratan-Tondangow plain. This plain area located in 800 - 900 meter above sea level.

3.1.2.3. Geology

Generally speaking, the geology of Minahasa and surrounding is formed by two rock

units, tertier volcano rock and quarter volcano rock. The first rock consists of silt,

tufa and brecci lava. Whithe the second unit consists of lava, bom, lapili and volcano

diust. Quarter volcano unit is resulted from eruption of young Soputan, Mahawu,

111-4

Lokon, Klabat and Tangkoko volcanos. Soputan and Lokon produced basaltic lava,

while the Mahawu and Tangkolto produced andesitic lava.

. - Rock formation in Lahendong area consists of tertier and kuarter rocks. Tertier

formation is the basic rock in Lahendong earth gas and consists of basic rock such as

silt rock, sand rock and breccica lava. While the quarter rocks are pyroclastic and

Pyroclastic rock is divided into silt and sand tuva rock units , tufa unit, breccica tufa

and silt rock units, and breccica tufa and scorea unit. Volcano rocks consists of

andesit Tampusu, riolit Lengkowan, andesit basal Linou and brecci andesitic Linou

Recent finding informs that Lahendong rock formation includes Lengkowan,

Pangolornbian, Post Pangolombian, Alluvium formation. Post Pangolombian formation

consists of undifferentiated Pangolombian, Tampusu, Kasuratan, and Linou

formations.

I Lengkoan formation consists of lava andesit, breccica, tuff and andesit

basalicdistributed in Lengkowan and surrounding rnouthaneous area. Pangolombian

formation can be found in Southeast and Southwest from Pangolombian crater.

Tampusu formation consists of lava andesit distributed in Tampusu its surrounding . Kasuratan formation consists of andesit basaltic distributed around Kasuratan and

Tondangow. Linou formation consists of lava, brecci and andesit basal and

distributed surround Linou Lake.

4.1.2.2. ~ u s t

Impact Source

Mobilization and demobilization of material (metal, gravel, sand, wood, cement) and

equipment (heavy transportation vehicles) would increase the dust concentration level

in the project area. The activity of transport vehicles would convey the air mass that

contained dust. This would increase the dust concentration in the surrounding air.

Tvpe of Impact

Increase of dust concentration would degrade the quality of amhient environment. n7e

finer the dust, the longer i t will stay in the air space.

Impact Maqnitude

The condition of roads is asphalted and the traffic intensity is low. It would lead to

relative low increase of dust concentration. The measured dust concentration ranged !

from 47 pg to 68 pg/ N M ~ . Due to the low intensity of transport vehicle, it is expected

that the dust concentration will not exceed the standard quality.

demobilization activities. Beside, vegetation in the area is not the habitat of fauna, but it

functions as niche.

4.1.3. Land Clearing and Maturation

4.1.3.1. Noise

Impact Source

Land clearing and maturation would increase, but not significantly, increase the.noise

level. Because the area is already plain and mature, there would be only land cleaning

activity that employs grass cut machine. This would not increase the noise level.

Lype of Imp&

Increase of noise.

Impact Maqnitude

By using grass cutter machine, the work will be completed in 1-2 days. The noise

created by machine is predicted to be 85 dB. This sound will not be heard by the local

people in the nearest village (Tondangow), that located + 500 rn away.

Remarks

The impact of this activity is considered to be temporary, 1 to 2 days. The impact

Experience during the construction of PLTP Lahendong I reveals that community would

not raise objections provided that there is measures conducted by the project

proponent in reducing the noise effect during cleaning processes of pipes.

Commissioning activity is the last step of construction phase. It means that the phase

will be followed by labbr release and recruitment of skilled worker and expert for

commissioning procedure as well as recruitment of operator in a limited number. These

activities would also bring impact on the local community living in! the vicinity of the

project. Following the labor release, the socio economic live would return to its original

condition. I n general, the people would think that release process is a common step

faced by contracted labor.

4.2. Operation Phase

4.2.1. Operation of PLTP

4.2.2.1. ' ~ o i s e

Imnact Source

Operating the generator unit would increase noise level due to the turbine. I f the

generator unit is not in function due to technical problems or maintenance, then the

scrubber area belong to Pertamina will excrete steam that also bring noise sound.

UKL and UPL PLTP LAHENDONG EXTENTION ( 1 X 20 MW ) I V - 9

Tvoe of Impact

Increase of noise level would decrease environment quality. The faster the machine

rotate, the higher the noise level would be. The more steam produced, the higher the

noise level is.

I m ~ a c t Maqnitude

If the unit is in operation, the noise level inside the generator house would be between

90 and 110 dB A, outside the house 65 to 70 dB A, and 50 dB A outside the PLTP.

Therefore, safety of operator and other workers working in powerhouse shall be taken

into attention.

I f the generator unit were not in function, then the scrubber area would crease noise

level of 90 dB A. According to experience, such a noise level will not annoy the local

people living in Desa Tondangow. I n short, increase of noise level will not disturb local

community, but workers operating within the generator unit area. ,

Remarks

Increase of noise level due to the operation of generator unit would be long lasting

process, 30 year or more during the operation phase. Impact indicator is Kepmenneg

4.2.2.2. Hydrogen Sulphide Gas

Impact Source

.'a_.

Operation of the PLTP could degrade air quality. The non-condensed H,S gas would

spread in the area through cooling tower. Besides, part of the steam would escape and

increase the H,S concentration in the air.

UKL and UPL PLTP CAHENDONG EXTENTION ( 1 X 20 MW ) IV - 10

Tvoe of Impact

The H2S spreads in the area would degrade the quality of ambient atmosphere.

Concentration of 2,5 mg/m3 or 1,82 ppm could irritate the eyes.

Impact Maanitude

According to field measurement, by operating one power unit having capacity of 1x20

MW will create HZS as much as 87 p g / N ~ ' to 114 p g / N ~ ' in the ambient air. Operating

2 units will produce 228 pg/NM3 or 0,164 ppm HZS.

Remarks

Impact of HzS gas is cumulative and it takes relative long time to see the symptoms.

Such a gas could also create a secondary impact, namely acid rain, if the HzS is oxidized

and reacts with water molecule in air to create sulphate acid (H2S0,). The impact would

be permanent, during the operation of PLTP. To reduce the amouht of H2S released into

free air is to utilize the gas or to increase the height of tower. The impact indicator is

Kep-50/MENLH/II/1996 on the standard quality of smell level that prescribed H2S

concentration of 0.02 ppm or 28 pg/m3.

Harapan Masyarakat Dan ketiga desa di sekitar proyek PLTP Lahendong Extention:

1. Desa Tondangow

a. Tenaga kerja yang akan direkrut sepenuhnya berasal dari desa setempat sesuai ketrampilan dan keahlian yanG tersedia untuk menghindari konflik sosial terbuka antar desa.

b. Pemasangan lampu penerangan pada jalan utama secara gratis sesuai proposal yang diajukan.

2. Desa Pangolornbian

Koropit diarahkan dikumpulkan dan masuk D. Pangolombian. Upaya ini dapat meningkatkan volume/debit air D. Pangolombian.

b. Oulet danau, yaitu pintu air dan saluran utama ke persawahan di 'rehabilitasi agar air terpakai lebih efisien.

c. Rehabilitasi inlet dan outlet dapat mengimbangi pernakaian air PLTP Lahendong dan turut mengembalikan fungsi danau Llntuk mengairi 60 ha lahan sawah yang sekarang ini hanya marnpu mengairi 113 bagian sawah dan budidaya ikan oleh penduduk seternpat pada telaga.

d. Memperhatikanl perbarui ijin pernakaian air .D. Pangolombian yang telah . berakhir sejak tahun 1999. e. Sebagai imbalan pemakaian air D. Pangolornbian aiharapkan PLN dapat

rnembebaskan tagihan listrik untuk penerangan jalan, kantor dan balai desa.

F. Pembayaran rekening listrik penduduk dapat dilaksanakan oleh desa bekejasama dengan PIN untuk rneningkatkan ~enda~a tan desa dalam - rnenunjang pembangunan desa.

g. Pernanfaatan jalan untuk angkutan alat-alat besar diharapka'n memperhatikan kelas jalan yang akan dilalui.

3. Desa Kasuratan

a. Diharapkan pelaksanaan rencana kegiatan terrnasuk tahap operasi dapat meyemp tenaga kerja sesuai ketmmpilam dan keahlian yang dimiliki.
