PEMETAAN DAERAH RAWAN BENCANA BERBASISKAN GIS PADA RUAS JALAN YANG TERIDENTIFIKASI BERDASARKAN INDEKS PAVEMENT
Abstract
The natural disaster can happen anytime and cannot be predicted
accurately where the disaster will occur. This study aims to identification and
disasters level of vulnerability mapping on the road, and to identify the type of
road pavement damage with PCI Method which conducted on parangtritis street
KM 16,5 – KM 20,5 with STA 21+800 – 25+100. mapping vulnerability of
disaster is using arcgis software with four types of disasters which is flood,
subsidence, landslide and earthquake and using landscape analysis method. The
result of analysis is show that the disaster with the highest vulnerability potential
are flood and subsidence, earthquake with medium potential, and landslide with
low potential. PCI method based on flood mapping, because this type of disaster
really influence the function of the road, so that can have an impact on comfort
and safety to the road users. PCI survey analysis along 3,3 KM. The results of the
PCI calculation were obtained at an average of 52.54, which means that the road
has fair class of damage.
