Abstract:
Pekanbaru City is one of the areas in Indonesia that is included in a flood-prone area. It
is even said that Pekanbaru City is included in the red zone related to flooding, judging
from the majority of areas which are swamp areas and river banks. This study aims to
determine the level of flood vulnerability in Pekanbaru City by using the Analytical
Hierarchy Process (AHP) method, which is an analytical method that can calculate the
relative level of a problem based on the weight of importance given to the criteria that
affect the problem. The criteria used as variables in this study to determine the level of
flood vulnerability in Pekanbaru City are rainfall, land use, and land height. The
calculation of the flood vulnerability value by multiplying the weights of each criterion,
results in the value of flood vulnerability at several points in Pekanbaru City. The final
results of the analysis are displayed using a Geographic Information System (GIS) in the
form of a map display of the level of flood vulnerability, which are Vulnerable,
Moderately Vulnerable, and Not Vulnerable with different colors at each level.
