| Summary: | DIY Province has approximately 110 km long coastline that is facing highly potential fishery resources of Indonesian Ocean. In spite of this, the fishery resources have not been optimally exploited. Fishing activities are still done using small fishing boats with outboard motors that only operate along the shore, not reaching offshore area and the Exclusive Economic Zone (EEZ). In order to increase fish catch, huge fishing vessels are required to reach offshore area and EEZ. The operation of huge fishing vessels entails the existence of large port. Serang River estuary in Glagah beach, Kulonprogo, DI Yogyakarta, has the potential to be developed as a fishing port. To support fishing port operation, a breakwater structure is needed to protect the port area from big waves.
At present, a breakwater has been built in Glagah beach. However, it could not function optimally due to some problems. The goal of this Final Year Project is to evaluate the planning of breakwater in Glagah beach so that constructive input could be given for the development of the breakwater in the future. Planning evaluation data are obtained from Bali Project by JICA, 1989 in form of deep sea rose wave and significant wave height data for 50-year recurrence interval. Besides, the data are also taken from Indonesian Department of Public Works (PU) DI Yogyakarta in form of topographical and bathymetrical data in Glagah beach, Kulonprogo, DI. Yogyakarta.
Based on the evaluation result, the length of East-side breakwater is 360 m at -15.5 m depth, while West-side breakwater length is 315 m at -10.8 m depth. The weight of tetrapod tip is 11.23 tons, the arm weighs 9 tons and the base weighs 6 tons. The breakwater is planned at Design Water Level (DWL) of +3.3393 m and top elevation of breakwater is designed at +8.83 m. The width of breakwater is 7 m at the tip and gradually decreases to 3 m at the base. The ship channel is 40 m wide with ship channel depth of 3 m. From the result of wave planning evaluation, it can be concluded that the breakwater design from evaluation could be applied as policy making alternative for local government in the development of Glagah Beach breakwater in the future. |
