JAKARTA - Plt. Head of the DKI Regional Disaster Management Agency (BPBD), Sabdo Kurnianto, explained the factors that caused the Jakarta floods which had occurred since Tuesday, January 18, until now it had not subsided for 6 hours.

This subordinate of the Governor of DKI Jakarta, Anies Baswedan, said that the failure to achieve the target of flooding could recede within 6 hours was due to extreme rains that returned when a number of points began to recede.

According to the chronology, extreme and heavy rains in the DKI Jakarta area since Tuesday at 15.00 WIB have caused inundation points in 57 RT. After handling in the field, Sabdo said that only a few puddles remained in 2 RTs at 21.00 WIB.

"Some of the inundated spots can recede in less than 6 hours despite extreme rainfall on January 18, 2022," Sabdo said in his statement, Thursday, January 20.

Then, it rained again with high intensity on Wednesday, at 00.30 WIB, causing the river to overflow. The heavy rain caused the return of inundation in 102 RT at 15.00 WIB.

"Inundation due to extreme rain on January 18, 2021 was able to be handled quickly, in less than 6 hours, but extreme rain again on January 19 caused inundation to occur again," said Sabdo.

Sabdo stated that the rain that fell again on Wednesday morning caused the Semongol and Begog rivers to overflow, plus an increase in sea water or rob.

Thus, in addition to extreme and heavy rainfall, tidal flooding in the northern and western areas of DKI Jakarta is the cause of inundation points in these areas that are difficult to recede. Because rob and extreme rain come at the same time.

"Officers in the field work together when they have to deal with tidal flooding and flooding from rainfall simultaneously in the northern and western areas of DKI Jakarta. Currently, the Fish Market Sluice Gate is already on Alert 4 so water will flow into the sea and pumping will be carried out again," he explained. .

Sabdo said the intensity and rainfall in some areas of DKI Jakarta Province during the period January 18 (07.00 WIB) - January 19 (07.00 WIB) was in the extreme category, which was more than 150 millimeters per day.

"If the rainfall is below 100 millimeters per day, we ensure that the inundation point will not last more than 6 hours. Meanwhile, the rainfall since January 18 has been above 150 millimeters per day," he added.

Until today, as of 12.00 WIB, the DKI BPBD recorded that the flood was still submerging 9 RTs in Tegal Alur Village, West Jakarta with a height of 40 centimeters.

Then, there are still 437 refugees from 141 families and 35 people from 22 families in Cengkareng Barat Village, West Jakarta.
