BPBD Bantul to Collaborate with UGM to Check Landslide-Prone Ground in Pajangan, Bantul

BPBD Bantul will collaborate with Universitas Gadjah Mada (UGM) to carry out checks at the landslide-prone site in Guwo, Triwidadi, Pajangan, Bantul. The inspection is planned for Monday, 9 March. “We have cross-checked, and on Monday the potential partnership with UGM will be examined to determine the causes. Whether the soil is too saturated or there is a plate substructure in the area,” said Bantul BPBD Secretary Ribut Bimo Haryo Tejo when contacted by detikJogja on Sunday, 8 March 2026. The checks, Ribut said, aim to confirm the causes of the landslide in Triwidadi. He believes unstable soil conditions are one of the causes. In addition, unstable soil exposed to water continually will eventually experience subsidence. “So in February there were heavy rains and I analysed the area there; Pajangan soil is unstable and saturated. Such soil, when there is too much water, gets eroded and will automatically subside,” he said. Meanwhile, up to now dozens of houses have been affected by the landslide. One house nearly collapsed because the soil at the bottom was eroded. “The landslide movement involves subsidence of up to 2.5 metres. The incident affected 20 houses, and one of them almost collapsed,” he said. Almost collapsed, he said, because the subsidence occurs at the bottom of the house. This poses a risk of collapse if heavy rain occurs again. “Fortunately, some of the houses are unoccupied, so there were no fatalities or injuries,” he added. On the other hand, Ribut revealed that the housing developers have committed to bringing in excavators to open drainage channels that stagnate in the housing area. “Then the residents affected will be compensated by the developers. Why? Because there has not yet been a handover of public facilities (fasum) with the district, so legally it is not yet the responsibility of the Regency,” he said.
