The South Jakarta Water Resources (SDA) Sub-agency has confirmed that permanent repairs will be carried out following a landslide along the Poltangan Connecting (Phb) Channel on Jalan Langgar II, RT 07/10, Pejaten Timur Urban Village, Pasar Minggu Sub-district. The work is targeted for completion within two months.

South Jakarta SDA Sub-agency Head Santo said the landslide had affected a section of the road around three meters long. However, the steep slope at the site means that comprehensive repairs and structural reinforcement are needed.

Santo said the landslide had affected about three meters of the road. However, the steep slope requires more extensive work to reinforce the site and ensure its stability.

"We are working with PPSU personnel to clear the debris first. Once that is done, our technical team and retaining wall workers will begin the permanent construction," he said on Thursday (11/12).

According to Santo, the limited access to the site would affect the mobilization of construction materials, which is why the work is expected to take two months.

"We will rebuild the retaining wall permanently along a 40-meter stretch, even though the affected section of the road is only three meters long. This is a preventive measure to reduce the risk of similar incidents, so we are making the most of this opportunity to strengthen the area," he explained.

Santo urged residents, particularly those living along riverbanks and drainage channels, to remain aware of potential hazards in their surroundings and avoid building houses directly on retaining walls.

"Building a house on top of a retaining wall is dangerous. If the ground shifts or the wall collapses, the building could also be brought down, putting its occupants in danger," he asserted.

Meanwhile, Mahesa Hendra, head of RT 07/10 in Pejaten Timur Urban Village, said the landslide had not only disrupted residents' access routes but also caused soil and collapsed gabion structures to bury and block the drainage channel. This subsequently led to flooding in lower-lying areas.

"Personnel responded quickly after the landslide by clearing debris, cutting up fallen trees, and removing accumulated waste that had blocked the channel to restore water flow," he noted.

He hoped the permanent repairs could be completed soon, noting that the soil at the site had become unstable and deteriorated. Several culverts and holes dug by animals had also contributed to the sinking of the ground.

"As a neighborhood administrator, I always urge residents living along the riverbank to keep the area clean and avoid throwing waste into the river to prevent blockages," he said.
