| Summary: | Multihazards phenomena of rob and coastal erosion in Demak Coastal Area was impacted to
the fishpond and mangrove ecosystem uses in particularly on socio-economic aspects. The
aim of this research are consist of to compose the multihazard map of rob and coastal
erosion, to predict the economic and social values of mangrove and fishopond uses and to
describe the correlation of economic impact with social impact by multihazards. The
sampling method in this research is purposive sampling. The analysis method for economic
value of mangrove ecosystem is using indirect value approach with biological, salt water
intrution defense, and phisical components. The analysis of economic value of fishpond are
consist of two main variable, productivity and feasibility. The productivity variable are
consist of profit and rentability components. The feasibility variable are consist of NPV, Net-
BCR, IRR and Payback Period Values. The analysis method for social values is descriptive
method. The analysis method for impact correlation of multihazard is Kendall�s Tau of
parametric quantitative statistics. The result of the multihazard map is devided into high,
middle, low and none level. The economic and social values change of mangrove and
fishpond uses are affected by multihazards level of rob and coastal erosion. The correlation
between social and economic impacts of multihazard is on low correlation and high affected.
