JAKARTA The areas of Jakarta, Bogor, Depok, Tangerang, and Bekasi have been surrounded by floods since Tuesday (4/3/2025) in the morning WIB with varying heights. This incident is referred to as the five-year cycle and is more severe than before.
Since Tuesday morning, netizens have been presented with a series of images and unpleasant videos showing floods in a number of areas in Jabodetabek. Hundreds of houses were flooded with water reaching a height of 3.5 meters, so only the roof was visible. Vehicles, both motorbikes and cars, and shopping centers were not spared from flooding.
Some residents chose to stay on the second floor of their house even though the flood was still inundating the settlement, while electricity at some points had to be extinguished for safety reasons.
Bekasi City, West Java, is said to be the worst. Activities in the city were even declared paralyzed because thousands of houses, roads, and government buildings were flooded with water.
Bekasi Mayor Tri Adhianto said eight sub-districts in Bekasi City were affected by flooding. Heavy rains that hit since Monday (3/3) night caused several embankments to burst because they could not withstand the overflow of water.
Of the 12 sub-districts, eight sub-districts in Bekasi City were affected. Meanwhile, the Jakarta Regional Disaster Management Agency (BPBD) revealed that 77 RTs were affected by flooding. According to BPBD, water in Ciliwung, Krukut, and Pesanggrahan rivers overflowed.
Meanwhile, in Tangerang, Banten, several flood-prone areas were again submerged in water, including Ciledug Indah Housing. The flood victims admitted that today's incident was much worse than the flood that occurred on January 1, 2020.
The Meteorology, Climatology and Geophysics Agency (BMKG) has given an appeal regarding extreme weather in early Ramadan since Monday (3/3).
"The extreme weather that causes hydrometeorological disasters in these areas occurs due to several atmospheric dynamics that significantly increase the potential for rain in several regions in Indonesia," in a written statement on the BMKG website.
Head of BMKG Dwikorita Karnawati said that high rainfall in the Jabodetabek area is predicted to continue until March 11. For this reason, BMKG will increase weather engineering, especially in the West Java region.
Weather engineering, also known as weather modification operations (OMC), is expected to reduce the intensity of heavy rains causing flooding in a number of Jabodetabek areas in the last three days.
City planning observer Nirwono Yoga said that weather modifications can only be done as a short-term solution, but do not solve the flood problem.
"To reduce the intensity of rain and distribute it to other areas, it is important, but does not solve the flood problem," said Nirwono.
He actually encouraged the government to make improvements to their respective urban spatial planning to minimize flood disasters. With extreme rainfall and predicted to increase again until March 11, according to Nirwono, the Jabodetabek area needs to be addressed, especially settlements located on riverbanks and surrounding areas.
"The settlements that are right on the banks of the river should be relocated to the nearest Rusunawa, the river body is dredged, widened, and greened," he said.
In addition to the existence of rivers, to reduce flooding that overflows through rivers, it is also necessary to optimize lakes, reservoirs, or reservoirs.
"If necessary, build new lakes or reservoirs to help accommodate river overflows and be restored into the ground and reduce river water discharge significantly so as not to overflow flood settlements," explained Nirwono.
In addition, said Nirwono, the entire city must rehabilitate all city waterways that are no longer able to accommodate rainwater, the waterways must be enlarged with channel dimensions according to the road class.
"The water channel is connected to the nearest SDEW (situ, lakes, reservoirs, reservoirs) to be accommodated by the overflow of rainwater," he explained.
Meanwhile, the manager of the Indonesian Environmental Planning and Infrastructure Campaign (Walhi) Dwi Sawung said that the flooding that occurred in Jabodetabek was not only due to rainfall but also due to the massive conversion of land functions in the upstream area.
Not only that, the number of land certificates that should not be used for residential locations is also one of the causes of flooding in Jabodetabek. These areas should be used to absorb water or function as infiltration areas.
"In plain view, it was all built in Sentul, Cikeas, Cileungsi, Hambalang," he said.

Dwi Sawung said the government should have a long-term comprehensive plan in dealing with watersheds (river basins), not following government administration limits. The government is also encouraged to evaluate housing permits and commercial areas to restore water retention and retention.
"Then repair the drainage properly, not because it follows the developer or is willing to pay," he concluded.
