Time bomb in Sidoarjo
AsiaViews, Edition: 32/III/Aug/2006
The mudflow catastrophe has changed the surface of Sidoarjo regency. An even bigger disaster awaits if the mud doesn’t stop flowing.
War!
AT asar (the third Muslim prayer of the day), the call to arms was heard from the Nurul Huda mosque. The villagers at East Renokenongo were asked to gather at the Surabaya-Gempol toll road, last Wednesday afternoon. Around 100 ran out of their houses, carrying weapons—crowbars, iron rods, wooden bats. War was declared as celebration of the nation’s independence drew near.
About 100 people rushed to the toll road. There, more then 50 people from the neighboring villages of Besuki and Jatirejo, were breaking rocks using plows. The Renokenongo villagers raised their weapons to prevent the forced break. After all, they depended on the embankments, made of sand and rock, for their future existence.
A quarter of a million cubic meters of mud, the height of a roof, was gaining in volume and it was just a matter of time before it would overflow. One of the four hamlets, Balongkenongo, has been flooded—428 houses in all. The danger pushed them to wage war on the eve of August 17, Independence Day.

The above war between two villages is a small example of a series of problems that came with the burning mud at PT Lapindo Brantas’ gas exploration location in Porong subdistrict, Sidoarjo regency, East Java. The mud started to flow on May 29, and so far the mud has inundated parts of the Porong area. At any moment, five villages could be uprooted. Around 8,134 villagers have fled to seek shelter.
Economic, environmental, and social losses can be calculated in no time. Lapindo claimed that it had allocated US$70 million (around Rp665 billion) in emergency funds to handle the toxic sludge. “Until now US$31 million has been used up,” said Imam P. Agustino, General Manager of Lapindo Brantas, to Tempo.
When the mud started gushing out, the volume was estimated at around 5,000 cubic meters. Today, it has reached 50,000 cubic meters a day. This is roughly the equivalent of 690 large container trucks.
If Banjar Panji-1 continues to discharge at 50,000 cubic meters daily, by October 31 the volume could reach 7.1 million cubic meters. At the end of the year, it will break through the 10-million-cubic-meter mark. This is twice the volume of the lava crater atop Mount Merapi when it erupts.
The danger becomes more imminent when the rainy season arrives at the beginning of November. Surabaya’s November 10 Institute of Technology (ITS) estimates that the rainy season will break the levees, causing the contained mud to overflow, the toll road to submerge, and the railroad to be engulfed with mud. That’s what lies ahead in the short term.
So far, three teams of experts have been formed to find a solution to the mudflow and manage the impacts. They work in parallel. Each team consists of representatives from Lapindo, the government, and several experts from leading universities.
Among them are experts from ITS, the Bandung Institute of Technology (ITB), and Gadjah Mada University. Team One, which takes care of the mud, is now struggling with the third scenario, whose short-term target (see Alarm Bells) is to stop the flow and find a rapid solution for the millions of cubic meters of mud on the ground.
The first scenario was drilling the old well—Banjar Panji-1—to determine the source of the discharge and plug it up. The result: total failure.
The team of experts then implemented the second and third scenarios, which essentially are to avoid the obstruction in the old well which failed in the first scenario. The second scenario was to drill from the mouth of the Banjar Panji-1 well. At a depth of 500 meters, the wall narrowed and could not be pierced. The equipment even had to be left behind at a depth of 300 meters. This scenario, too, was a total failure.
Only the third scenario is left. At this stage, a relief well was dug first. Once again, it had to be stopped—at least for the time being. To quote the General Manager of Lapindo, Imam P. Agustino, “The platform was flooded, so the third scenario must be postponed.” The intention is to wait until the location is safe from the stagnating water.
The schedule has been delayed by a month to the end of November or the middle of December. Learning from the experience, Lapindo decided to drill in three points simultaneously last Friday. However, there’s still a possibility of failure. Here are the calculations.
The three scenarios are based on the hypothesis that the mud came from a crack in the well of the Banjar Panji-1 wall. But, there is another hypothesis: what happened was a volcanic phenomenon, like in Bledug Kuwu in Purwodadi, Central Java. Until today, it’s still discharging sludge, forming a swamp.
So, a fourth scenario must be prepared. Rudi Rubiandini, member of Team One, explained to Tempo that volcanic mud could only be overcome by operating three or five relief wells simultaneously. All wells are used to surround the cracks where the mud surfaces. The problem is, “It’s expensive and time-consuming.”
For example, a rig and its operational costs require Rp95 billion. The costs can escalate because contractors and the rental charge of drilling equipment will be higher in danger zones. Assuming normal costs, the five wells will require Rp475 billion.
Even if the funds are available, however, “today it’s hard to obtain an available rig amid the soaring oil prices,” said Rubi.
It’s no wonder that some experts are losing hope. “I doubt that the mudflow can be stopped in a matter of months,” said Amin Widodo, geologist and head of Disaster Studies at ITS. Other experts are even considering the possible end of Porong.
Rovicky Dwi Putrohari, an independent geologist, wrote that in Porong-1 well location, 7 kilometers to the east of Banjar Panji-1, were geological indications which “showed mudflows happening in prehistoric eras.” That was his analysis. Rovicky noted something worrying: the mudflow in Porong-1 would not stop for decades or even hundreds of years.
* * *
Banjar Panji-1 poses a question. What will happen if there’s no way to stem the flow of mud? Without expanding the dykes or embankments, the mud is certain to flow in all directions. Until two weeks ago, the capacity of the levees was only 767,000 cubic meters.
The Environment Department said that to contain the mudflow for the next three months, they were preparing 150 hectares of new dykes. As an anticipatory measure, there are 342 additional hectares that could meet the need for the next nine months.
The problem is, the Meteorology & Geophysics Agency predicts that the rainy season is coming in about 30 days. If that’s correct, then the dams will not be able to contain the mud. Mud will flow in all directions, dirtying the surrounding areas. “It’s like waiting for a time bomb that will explode at any moment,” said an official at Sidoarjo.
Whether it explodes or not, the surface of Sidoarjo has changed. The area in which 19 Lapindo gas wells are located is Surabaya’s satellite town. Some of the people commute from Sidoarjo to Surabaya. They live in houses on both sides of the toll road, including around the center of the mud discharge.
In the emergency roster, there is the Tanggulangin Anggun Sejahtera Housing Complex, standing by in case the mud demolishes the 6,000 houses along the sides of the dam.
The regional space plan for Porong is certain to be adjusted. If the worst prediction comes true and the majority of Porong is inundated, “the region will be converted into an industrial zone,” said Regent of Sidoarjo, Win Hendrarso. Previously, Porong was planned as a residential area.
Dozens of factories are already submerged. What remains of PT Catur Putra Surya, where labor activist Marsinah used to work, are only its roofs.
What worries Win is December, the month with the highest rainfall. If the dam is seen to be inadequate, “We have no choice but to divert the mud directly to the sea, through the Porong River,” said Win.
Lapindo recommends the same solution. They reason that, rather than wait for discharge pipes to be completed, it’s better to temporarily use the river to let the mud discharge, for example, for three months. “This is not the best choice. But at least, this is the best of all options,” said Bambang P. Istadi, Explorations Manager of Lapindo.
This recommendation has been approved—with conditions—by the Sidoarjo Regent. Moreover, Vice President Jusuf Kalla has given the green light for the last scenario to be the option, namely to prioritize saving people, the toll road, the railroad and the environment.
Unfortunately, the mud will exacerbate the damage to the Porong River ecosystem. And, when it enters the sea, the mud will automatically pollute the Madura Strait and the surrounding seas. The 1,600-hectare fishponds on the shores of Sidoarjo will also be impacted. What if that happens?
“Let nature do its work,” said Amin Widodo in response to Tempo’s question. This is an ancient formula, relying on nature’s mechanism to restore life. In the meantime, the people must still use “weapons” to fight the attack of the mud.

Hey there! This post could not be written any better!
Reading through this post reminds me of my old room mate!
He always kept talking about this. I will forward this page to him.
Pretty sure he will have a good read. Thank you for sharing!
Hmm it seems like your blog ate my first comment (it was extremely long) so I guess I’ll
just sum it up what I submitted and say, I’m thoroughly
enjoying your blog. I as well am an aspiring blog writer
but I’m still new to everything. Do you have any helpful hints for newbie blog
writers? I’d certainly appreciate it.
Hazards using shock absorbers or springs. Discounts are available for people wanting a set of three or more tweets.
Make sure you have enough supplies to keep close track
of fares and cheapest strategies for travel. Airlines often
charge extra for exit rows and bulkheads because they are
capable of inflicting this damage.
Nice post! This really helps me to find the answers to my question. Hoping that you will continue posting an article having a useful
information. Thanks a lot!
A humankind begins icy his insight teeth the earliest often he bites off more than he can chew.
when it will stop anyway?? where is your responsibility Bakrie??
nice…
relax don’t worry, hey afterall it’s only mud, why be so serious……..look at the bright side, mud for free. Compensation? let the gov do the job, it’s only tax payers money afterall
do you know any information about this in english?
Hi Sidoarjo community
The flood mud is only litle tried, Allah is highty mighty

Metode ini bisa aja dikaji, kalau area dalam radius 5-10KM sudah dikosongkan semua kemudian pusat semburan diledakkan dengan diameter 1KM, maka akan terbentuk kaldera LUMPUR, tapi apakah tidak akan terjadi pergeseran / pergerakan tanah didalam bumi sehingga mengakibatkan gempa TEKTONIK ?
3 things I suggest.
1 – Drill holes around the site 1 km from the center and pour in cement to form a wall underground almost or into the last part of the formation.
2- Drill at an angle holes around this site say 500meters from the center point at an angle, so that the top of the bore holes are in a smaller ring and where the bottom fo the bore holes are creating a larger ring – almost to the same depth as the lower formation then I would set some charges up the drill holes say every 20 meters and then blast the formation.
2 – within the 500 meter diameter I would pile up aa huge amount of stone and clay gravel and such like. When you blast point 2 then point 3 would fall into the hole – equilibrium will be reached.
Will take some money and a little thinking and getting people on side.. . . . .
Hi,
Do you know anything about the people who were affected by the mudvolcano…
MM
what if the mud doesn’t stop flowwing?
Hello, would you by any chance be able to tell us some information about the Internally Displaced People of Sidoarjo? Thank you very much in advance…
MM
Hi Peter,
go to Istana Merdeka in Jakarta, Indonesia, you will meet the guys who should be responsible having dinner on gold plate and diamond goblet watching tvl aughing at the poor people crawling in mud.
hi
now, there is a lot of opportunities to this disaster condition. however, difficult to enter to the system. it takes longer time to settle since there is no clear organisation and coordination. so just relax and see what’s happend on next surprising.
How long have the mud flows at Bledugkuwu in Purwodadi in Centel Jva been active?
what kind of new topography and ecology has i created..
Has anyone investigated this similar scenario?
You have lost this problem.Why did the drilling go ahead after warnings in the first place?I do like the idea of throwing the disaster back to the planet and nature to sort out for you though.The best of luck in your feeble efforts.
Peter,
If you do have a solution then stop sitting on your back writing such messages and just waiting to be contacted by someone. Call the Indonesian embassy in your country and they could provide you with the correct contact information.
Our proposal is based on an enzymatic fluid that will bond the clay soils under heat and pressure. I urgently need to contact the head of the Government Disaster Team, anyone with contact details please email mail@mckmid.com
When most likely mudflow would not stop for hundred years, why you peoples don’t think how to manage mud flooding?
Like Peter McKenzie-Midlane, I also am working on a possible solution. I live in Central Java (here for 20 years), and am studying the problem and possible solution. I can get in contact and be your liason.
Peter, if you see this and want to contact me, use .
I have a project group that has a possible solution to permanently stop the mud flow. I need contact details of all stakeholders concerned and soil data of the area in question.
Imagine the worst case scenario, the mud packs of the porong river, the pumps can not pump thickened mud through the pipelines, and all the pathetically constructed dams collapse due to water migration from the heavy rainfall. Thats possibly the scenario that is the most realitc one. Indonesian task forces dont seem to get the picture.
f**k you lapindo
