| dc.description.abstract | Tanjung Rejo Village, located on the east coast of North Sumatra, often experiences
tidal floods. Every year, the area affected by tidal floods expands and inundates the
community's land use area so that mapping of tidal affected areas is needed as a
disaster mitigation step. This research aims to determine the distribution of the level
of vulnerability and analyse the type of land use in the tidal flood prone area of
Tanjung Rejo Village. The parameters used include land elevation, slope, distance
from the coast, distance from the river, land cover and soil type. Each parameter is
given a weight and then overlaid by adding up the total score of all parameters that
affect flooding. The results of the study show that out of 342 ha of the study area,
180.94 ha or 52.78% are vulnerable areas, 152.02 ha or 44.34% are moderately
vulnerable areas, and 9.87 ha or 2.88% are not vulnerable areas. Land use affected
by tidal floods in the prone class is dominated by coastal mangrove areas covering
74.54 ha, water bodies covering 58.73 ha, ponds covering 16.63 ha, palm oil
covering 12.81 ha, and open land covering 12.61 ha so that land use management
by the community needs to be evaluated to reduce the negative impacts of tidal
floods. The results of the ground check in the field and the confusion matrix test
showed an accuracy rate of 80%, indicating that the resulting map has a
satisfactory level of accuracy. | en_US |
