South Jakarta Mayor Muhammad Anwar led a large-scale cleanup involving 400 Rainbow Troops personnel to dredge the Krukut River on Jalan Bendungan Udik in Karet Semanggi, Setiabudi Sub-district.

Anwar said the cleanup aimed to address recurring inundation in the area.

"In this location, flooding typically reaches depths of up to 70 centimeters," he said on Sunday (4/12).

He explained that the large-scale effort, including dredging the Krukut River and nearby drains, is expected to help prevent inundation.

"At least, if flooding does occur, it will recede more quickly. We will continue to optimize efforts to address inundation ahead of this year's rainy season," he added.

He also reminded residents not to occupy riverbanks or litter, as both can trigger flooding and inundation.

"This requires collective responsibility. The government will continue educating the public. Going forward, half of waste must be managed at the source, with only the remainder disposed of at TPST Bantar Gebang. The policy is currently being rolled out and will take effect on August 1," he emphasized.

South Jakarta Water Resources Sub-agency Head Santo said the cleanup also deployed two amphibious excavators and 10 dump trucks.

"We started the work today and are targeting completion by August 10, meaning a four-month timeline. The dredging is challenged by buildings along the riverbanks, so we must proceed carefully to avoid landslides," he noted.

According to him, the dredging along the Krukut River in Karet Semanggi is expected to remove 6,842 cubic meters of sediment and waste.

"To address flooding here, we are also optimizing the existing floodgates, which will be equipped with pumps," he added.

Meanwhile, Novita, Head of RT 02/04 in Karet Semanggi, expressed appreciation for the mayor's direct involvement.

"We are very grateful that the mayor personally led the cleanup and dredging of the Krukut River. Hopefully, flooding will no longer occur," she said.
