PEMETAAN MULTI-RAWAN BENCANA BERBASIS GIS DAN IDENTIFIKASI KERUSAKAN RUAS JALAN MENGGUNAKAN METODE PCI
Abstract
The Parangtritis road KM.8 s.d KM.12 DI Yogyakarta has considerable
potential for disasters such as floods, earthquakes, landslides and subsidence. This
study aims to create a multi-disaster preliminary map, determine the level of
disaster hazard class using ArcGIS software, and identify damage in visual on the
street. The method used in making tentative maps is the method of scoring (scoring)
and weighting, f urthermore identification of road damage using the PCI method
was carried out based on the disaster-prone map that was flooded, because the
flood disaster was the most influential disaster on the functional road and road user
safety. The results of the study show that floods and subsidence disasters are high
potential disasters in the research area. Based on the results of the disaster map
which has the potential of flooding along the 1.5 km, so that the results obtained
from testing the damage to the road that has the potential for flooding, the average
PCI value is 41.53 (fair). PCI testing starts from sta. 12 + 600 d. Sta. 13 + 600 and
15 + 800 d. Sta. 16 + 300.
