tetaplah mencintaiku: self-inflicted disaster

March 27, 2009






… wadow, bencana lagi… situ gintung dan sekitarnya dari google maps dan foto sisi situ yang jebol (detik.com;okezone)

… tanda2 alam dan dampak awal bencana sebenarnya sudah terjadi sejak pukul 5 sore hari saat hujan lebat menyiram situ itu, dan longsoran kecil sudah mulai terjadi … rakyat yang tinggal di sekitar tanggul sudah waspada dan bersiap mengungsi, tapi ragu2 karena gejala2 awalnya begitu kecil, hanya longsoran2 kecil … semakin malam semakin nyata longsoran batu terjadi … sekitar dini hari pukul 2.00, longsoran sudah makin jelas, tapi warga sekitar tanggul masih belum juga bener2 ingin beranjak sementara polisi sudah mulai memperingatkan warga … longsoran tanggul makin besar sampai dengan puncaknya, diiringi suara dahsyat, sekitar subuh, tanggul jebol besar sekali, banjir bandang setinggi 15 meter segera menyapu kawasan di sekitar situ sampai dengan beberapa kilometer jauhnya, bahkan memasuki aliran kali pesanggrahan… korban tewas kebanyakan berada di kawasan yang lebih jauh daripada lingkar dekat tanggul, karena mereka tidak menyadari bahaya yang mengancam dan sedang tidur terlelap … bahkan menurut tvone, saat ini (jam 1255 waktu jakarta) masih terjadi longsoran2 lanjutan … mungkin karena tanah situ memang labil …

Tanggul Jebol Karena Sudah Uzur
Djibril Muhammad

(inilah.com/ Wirasatria)
INILAH.COM, Tangerang – Penyebab jebolnya tanggul Situ Getung, Tangerang karena usianya sudah tua. Sebab tanggul yang berdekatan dengan kompleks perumahan Cirendeu Permai Tangerang itu, sudah ada sejak zaman Belanda.

Menurut Kepala Balai Besar Wilayah Sungai Ciliwung dan Cisadane, Sutoyo Subandrio Pitoyo, ketika hujan berlangsung seharian pada Kamis (26/3), yakni dari pukul 16.00 – 21.00 WIB, warga setempat sudah memberitahu akan kondisi tanggul. Bahkan di sebelah hulu tanggul terjadi hujan es.

“Kemudian terjadi kenaikan muka air yang cepat. Kemudian air terus naik sehingga tanggul tidak mampu mengalirkan air ke luar,” ujar.

Selain itu, ujar Suroyo, disisi lain tekanan terus menerus terjadi sehingga menebabkan gerusan. Kemudian bendungan pun longsor dan roboh. Urukan jenis apapun, lanjut dia, jebol bisa terjadi limpasan.

“Karena hujan deras sehingga bendungan yang dibuat pada jaman belanda tidak mampu menampung air. Luas danau ini 21 hektar. Jadi lebih dari satu juta debir air yang mengalir ke bawah,” bebernya.

Ia mengatakan, ketika berbincang dengan Wakil Presiden Jusuf Kalla, dirinya ditanya seputar teknis tanggul. “Debit air selama hujan bertambah dengan sekitar, dan lama kelamaan danau ini tidak menahan debit air sehingga akhirnya jebol,” ucapnya. [jib/ana]

JAKARTA, KOMPAS.com — Wilayah Danau Situ Gintung harus distandardisasi ulang. Banyaknya permukiman penduduk membuat danau menyempit.

“Wilayah ini harus distandardisasi ulang. Dari atas sudah menyempit, jadi yang di pinggir kena,” ujar Wakil Presiden Jusuf Kalla saat meninjau lokasi tanggul yang jebol, Jumat (27/3).

Ini, lanjutnya, juga untuk mencegah terjadinya jebol ulang. “Jadi jangan sampai kena dua kali,” lanjutnya.

Tanggul Danau Situ Gintung jebol karena tidak kuat menahan banyaknya air. Volume air terus bertambah akibat hujan deras yang turun di Jabodetabek beberapa hari ini.

“Kemarin kami mendapat penjelasan, ada hujan deras, bahkan hujan es yang terjadi di atas ambang normal, air terus naik. Tapi bendungan tidak bisa mengalirkan air, terjadi overtopping. Lalu ada pelimpasan dan terjadi gerusan di bawah sehingga tanggul tergerus. Urugan dalam bentuk apa pun tidak akan kuat,” jelas Kepala Balai Besar Sungai Ciliwung-Cisadane Pitoyo Subandrio ketika meninjau lokasi bersama JK.

BOB

kira2 berapa LITER AIR BAH YANG TERCURAH: (cara bego) luas situ 10 hektar, dalam situ 15 meter: 10.000 m2 X 15 m=150.000m3 = 150.000 X 1000= 150 JUTA LITER … itu hanya isi situ, kalo ditambah curah hujan… pasti lebih dari 150 juta liter dong

Torrential rain caused a dam to burst early Friday, sending a wall of water crashing into a crowded neighborhood just outside Indonesia’s capital. The flood killed at least 50 people, left more than a dozen others missing and submerged hundreds of homes.

A rescuer searches for flood victims on the outskirts of Jakarta March 27, 2009.
Rescuers, some using rubber rafts to reach victims, predicted the death toll would rise.

Health Ministry Crisis Center chief Rustam Pakaya said the dam which was built decades ago, when the country was still under Dutch colonial rule broke at around 2 a.m., while most people were sleeping.

In some places, water levels were roof high.

A 9-year-old girl was found unconscious on top of one home after waters receded, but she died on the way to the hospital, said rescuer Toni Suhartono, adding that the girl’s parents and sister were among the missing.

Elsewhere, bodies were seen floating amid chairs, clothing, sandals and other debris. Telephone lines were toppled and cars swept away, some parked in driveways and ending up in parks or intersections hundreds of feet (meters) away.

“A flash flood came suddenly and was horrifying,” said Seto Mulyadi, adding that the water smashed all the windows and doors on the ground floor of his house, while he, his wife and four children were sleeping upstairs. “My house is a dreadful mess .. Thank God my family is safe.”

Some people living near the dam said they heard sirens before the disaster, which followed a four-hour downpour. Others were caught completely off guard.

Pakaya said at least 50 people were killed and more than 400 houses submerged.

The 32-foot-high (10-meter-high) dam, which was holding back about 70 million cubic feet (2 million cubic meters) of water at a lake fed by the Pesanggrahan river, was built up to one century ago, according to one city official, Dadang Arkuni.

Some authorities said heavy rains caused the dam to first overflow and then, because the foundation was not made of concrete, to burst.

Hundreds feared dead as Jakarta dam bursts, flooding homes

Stephen Fitzpatrick, Jakarta correspondent | March 27, 2009

Article from: The Australian
HUNDREDS of people are feared dead after a dam burst its walls in Jakarta early this morning, causing a “tsunami” that destroyed homes as residents slept.

The death toll continued to mount through the day as rescuers pulled bodies from the houses around the largely middle-class university district of Ciputat, not far from the city’s centre.

Dozens of victims had already been recovered by the middle of the day, after the disaster at Lake Gintung struck before dawn.

“It was just like being in the middle of tsunami,” online news service Detik.com reported one survivor as saying.

Minu, the oldest daughter of Seto Mulyadi, the head of the national commission for children’s protection, told the news service that her household was fast asleep when the lake, which covered an area of 21 hectares, burst its banks.

Suddenly, she said, there was a great commotion and the screaming of people.

“They were shouting, the water’s coming in, the water’s coming in, and our dogs were barking,” she said.

She heard what she thought was someone knocking on the door of her house, until she realized it was the rushing water, which in some areas reached a height of several metres.

Ms Minu said she gathered her family and household staff and rushed to the upper floor of the home to await rescue.

She said a neighbour in the middle-class Cireundeu Permai housing estate narrowly escaped with his life after trying to escape by car.

“At the moment the water swept through, he immediately ran to the garage and tried to get his car out, but the water was already rising and the engine wouldn’t start, so that suddenly the water was too high. He got out of the car by smashing the front windscreen,” Ms Minu said.

However other residents said they had been aware of cracking in the lake’s retaining wall since around midnight, with heavy rain having fallen since yesterday afternoon. A Dutch-era brick bridge was swept away before the wall itself gave way.

Search and rescue personnel, as well as nearby residents, used rubber boats to rescue those they could, with hundreds of homes destroyed.

Deputy President Jusuf Kalla and Co-ordinating Minister for People’s Welfare Abu Rizal Bakrie rushed to the area to inspect the damage, and President Susilo Bambang Yudhoyono was being urged to declare a state of emergency.

On the campaign trail in West Java for upcoming parliamentary and presidential elections, Mr Yudhoyono said he would “take a break” from his stump tour to give directions for emergency measures to be taken.

Mr Kalla said the Government would “provide emergency help to the victims. For those whose homes were destroyed, the Government will help with the repairs”.

Danang Susanto, an official at the health ministry’s crisis centre, said at least four children were amongst the confirmed victims.

“All of them drowned,” he told AFP.

“The dam burst happened at 2am but before that there was heavy rain and wind, many trees were uprooted. People were still sleeping and couldn’t do anything,” he added.

“Many people are still trapped and the rescue is ongoing. We’ve sent out 10 rubber boats to evacuate the victims.”

“Right now residents are being evacuated. About half of them are still on rooftops waiting for help,” said Rustam Pakaya, who heads the crisis centre.

Victims were being evacuated to dry ground at the nearby Muhammadiyah University and in local schools.

A worker at Jakarta’s Fatmawati hospital, Roni, told AFP the hospital had already received the bodies of four victims, including a nine-year-old girl.

“They were all blue and covered in mud. The nine-year-old was found on the roof with head injuries,” she said.

Television images showed people frantically evacuating flood victims from submerged homes via twisted alleyways in the stricken neighbourhood, a mix of large middle-class homes and crowded traditional kampungs, or urban villages.

Houses and concrete buildings were buckled by the force of the waters, and aerial footage showed the lake nearly drained.

“The floods caused a landslide, destroying my house and another one below it,” local resident Mabruri told TV One. “Whenever it rains, water rises. But never like this.”

State power company PLN shut off electricity to the flood-hit area, where five of its power stations were submerged, Detikcom reported.

The area is regularly hit by flooding during the rainy season, which is set to continue for a few weeks yet, but resident Minu described today’s disaster as “extraordinary”.
“Small tsunami” kills 50 after Indonesia dam breaks

(Updates death toll, adds quotes, details throughout)
JAKARTA, March 27 (Reuters) – A dam on the outskirts of the Indonesian capital, Jakarta, burst early on Friday, killing 50 people and flooding hundreds of houses nearby, officials said.
Rustam Pakaya, a health ministry official, said 50 bodies had been recovered so far and hundreds of houses were under 2 metres (7 feet) of floodwater.
“Hundreds of houses are flooded, tens of houses damaged, it was like a small tsunami,” he said.
Police said they were still searching the area for more casualties. Metro TV showed rescuers wading up to their chests in floodwater as they put the injured on stretchers.
The dam, which was used to retain water in Lake Situ Gintung in Tangerang District, 20 km (12 miles) southwest of central Jakarta, broke early on Friday morning following torrential rain.
President Susilo Bambang Yudhoyono cut short a trip to Bandung, West Java, where he was campaigning ahead of April 9 parliamentary elections, to visit the disaster scene.
Vice President Jusuf Kalla went to the area earlier on Friday and promised the government would repair the dam immediately and provide help with rebuilding homes. (Reporting by Telly Nathalia and Dicky Kristanto; Editing by Sara Webb and Paul Tait)

Dam bursts outside Indonesian capital, killing at least 50
Death toll expected to rise, officials say

A dam burst on the outskirts of Jakarta before dawn Friday, sending a flash flood into a crowded residential neighborhood in the Indonesian capital, submerging hundreds of houses and killing at least 50 people, officials said.

Rescuers predicted the death toll would climb, as most people were sleeping when the dam exploded.

The failure of the decades-old dam, which burst at around 2 a.m. local time following hours of torrential rain, completely destroyed some houses and inundated at least 400 others, Health Ministry crisis centre chief Rustam Pakaya said. Floodwaters were up to 2.5 metres deep in some areas, police and witnesses said.

Water levels reached rooftops in some places. Metro TV footage showed several bodies floating amid chairs, clothing and other debris. Telephone lines were toppled and cars swept away, some as far as hundreds of metres.

At least 50 people died, Pakaya said. It is not immediately clear what caused the dam to break.

“A flash flood came suddenly and was horrifying,” said Seto Mulyadi, whose car was washed nearly 100 metres from his driveway into a public park. “My house is in a dreadful mess…. Thank God my family is safe.”

Mulyadi said he heard a siren sound at the dam before the water smashed out all the windows and doors and inundated his home. His wife and four children were all sleep upstairs and were unharmed, Mulyadi said.

A rescue worker identified only as Toni told El Shinta radio that another 19 people were being treated at nearby hospitals.

It was unclear what caused the failure of the 10-metre-high dam, which was holding back around two million cubic metres of water at the Pesanggrahan River, according to South Jakarta police Chief Makmur Simbolon.

Edi Prasetyo Utomo mengatakan bila pengelolaan dilakukan sesuai dengan wawasan lingkungan, malapetaka itu sebenarnya bisa dihindari. Banyak tanggul dengan tipe itu yang tetap aman, bahkan tanggul di Belanda pun letaknya berdampingan dengan permukiman. “Yang harus dilakukan adalah pemeliharaan dan pemantauan,” ujarnya. “Sepanjang tanah urukan itu impermeable atau air tidak bisa lalu lalang dan semua parameter pemeliharaan dam dipenuhi tak mungkin jebol.” … ini yang gw sebut sebagai self-inflicted disaster…
