PERENCANAAN PERLINDUNGAN PANTAI SAYUNG DEMAK
ABSTRACT: Sayung shore in
Demak is one of many shores that its coastline has been receded quite alarming.
Bedono village have the worst damage, now just five of seven hamlets exist in
Bedono. Senik and Tambaksari are two retreat hamlets due to erosion. Moreover,
the access roads among those hamlets were disconnected, and the sea water had
flooded the settlement residence. From the years of 2000-2005, 325 Ha fish
ponds were lost due to the erosion, and 110 Ha were flooded by the tide.The
objective of this study is to plan Sayung shore protection. Location of the
study is on western side of Sayung river with the length of coastline around
3.9 kms.The aspects of analysis are tidal currents, wave generated by wind,
coastal morphology, and geological engineering. There are four alternatives of
shore protections which are breakwater, revetment, groin and
combinations.Combination of revetment and breakwater were analysed against
coastal morphology, function, low cost structure, and workability. Revetment
along the 2.3 kms will be built on the western side, and on the eastern side
three units of breakwater, which each breakwater length is 100 m with 40 m
breakwater gap.
