Flood issue remains worrying for Jakarta residents. In addition to natural factors, various social factors also contribute to triggering flood in the city. As a result, these two factors hinder Jakarta to eradicate flood. Consequently, policies and regulations should be initiated to realize flood-free Jakarta.
Head of Information Data and Public Relation for National Disaster Mitigation Agency (BNPB), Sutopo Purwo Nugroho, stated that before 1970’s, natural factors became dominant factor of flood cause. Yet, nowadays, the cause has gotten complex as human actions also badly affect it. In his opinion, various handling efforts fail because of more numerous and complex causing factors of flood.
According to him, the effort of flood handling until 2014 is considered cannot overcome flood spots in Jakarta. Thus far, Jakarta Provincial Government could only able to reduce 15 out of 78 spots through East Flood Canal (KBT).
“As many as 6 flood spots will be reduced if river normalization in East Flood Canal (KBT) is carried out. While for normalization against Pesanggrahan, Angke, and Sunter in 2011-2014 with budget amounting to Rp 2.3 trillion is only reducing 10 spots,” explained Nugroho, Sunday (12/23).
In addition, the river dredging project or Jakarta Emergency Dredging Initiative (JEDI) in Cengkareng Drain, Sunter River, KBB, Cideng, Angke, etc in 2013-2014 would only able to reduce 20 flood spots and leaving 27 spots. “This amount was recorded due to there aren’t any new flood spots,” he told.
Regarding inundation on Jl. Sudirman, Jl. MH Thamrin and Jl. Gatot Subroto on Friday (12/21) and Saturday (12/22), these roads are not included on 78 flood spots. “Yet those roads still inundated yesterday,” he exclaimed.
On Saturday (12/22), at least there were found 22 puddles in the city, including Jl. Sudirman and Jl. Thamrin. The condition was worsened because heavy rain also happened in Puncak that caused water debit increased approximately 110 centimeters in Ciliwung River and reached 3-alert.
Nugroho also recorded on Sunday (12/23) around 3 AM, the 1-meter-high flood also hit some areas in Jakarta. They were Makasar, Bidaracina, Kampungmelayu, Cawang, Kramat Urban Villages and other areas in Ciliwung upper Riverbank.
