Semarang is one of the large cities in Java that is very prone to
tidal flood or locally known as ‘banjir
rob’. In order to reduce the tidal flood risk, disaster managers and city planners requires a wellwell-planned
natural disaster risk management based on disaster risk map of the city area. In order to develop the
disaster risk map, fi rstly the validation and prediction of the tidal flood were done in order to produce a
hazard map on the tidal flood. Subsequently, the maps of vulnerability and capacity of the study area were
produced based upon VCA (Vulnerability Capacity Analysis) by using fuzzy logic and weighted method
approach. As a comparison to that, the calculation of tidal flood risk was also done in accordance to the
regulation of The Natural Disaster Risk Management Head Kepala Badan Penanggulangan Bencana
Alam (PERKA BNPB) No . 2 year The result suggests that the risk for tidal flood in Semarang for
the year of 2015 is 8.339,31 hectares, flooding 25,10 % of the total Semarang areas in 9 sub districts of
73 community areas. From the risk assessments using VCA formulation, it can be concluded that the low
risk is on 15 community areas (218.17 hectares), intermediate risk on 48 community areas (1.116.38
hectares), and high risk on another 61 areas (6.671.36 hectares). In addition to this, the research also
conclude that the u se of fuzzy logic method in modeling vulnerability can gives a good result for
supporting tidal flood risk assessment in Semarang city. |
