On Friday, March 27, 2009, Situ Gintung dam at Cirendeu, Tangerang, southeast of Jakarta, has broken-down and the water flooded like a small tsunami, washing away cars, houses and settlement area. Ninety nine people were killed and 102 others were missing (update the number of victims from www.kompas.com on Tuesday, March 31, 2009)
From all of that, I am interested with the three important notes that I find on a blog of Jusuf Kalla, who at this time as Vice President of Indonesia.
First, it is indeed the embankment that broken-down was caused by excessive water debit. Situ Gintung levee was originally built on Dutch colonial authorities era, only able to accommodate 1 million cubic of water, while the debit of water before the incident has reached 2 million cubic of water debit. There should be early warning for residents who live around the embankment when felt there was something that threatens the safety of citizens. In Situ Gintung actually already there, but work less well.
Second, allotment of land around the flood plains has been infringe the rules. If refer to the rules then there can be no building within 30 meters distance from flood plains, in order to become water absorption area if overflow occur unexpectedly. But, housing has been built in flood plains at Situ Gintung region, so there is no water absorption area and at the time the embankment (dam) broken then the water immediately flooding in settlement residents. Therefore he request that allotment of land around the flood plains all over Indonesia should be re-standardization, for the sake of safety for all of us.
Third, for people who live in areas prone to disaster, need to prepare emergency response system independently, which can be used when something happens while waiting for help from the authorities. In that way, the number of victim could be minimized.
I hope to re-standardization of flood plains can be done immediately. End of word, this is another "natural process" from God which can not be avoided, even though I feel very sad to know these disaster. All that we can do is using technology for early warning, prepare ourselves and give rapid-help to minimize the victim. What is your opinion about this?
