Pantai – pantai ini berkarakteristik berpasir hitam dan bergelombang tinggi.

Penelitian ini bertujuan mengetahui nilai indeks kerentanan pantai, dan kerentana sumberdaya perikanan berupa nilai ekonomis dan keanekaragaman jenis sumberdaya perikanan (ikan Sidat dan udang Vannamei) di pantai Kabupaten Purworejo. Penelitian ini dilakukan pada 2 Februari hingga 28 Oktober 2015 mengggunakan metode analisa kerentanan CVI ( CoastalVulnerability Indeks ) dan dimodifikasi sesuai dengan lokasi dan objek penelitian. Metode pengambilan data dilakukan pada lokasi pengamatan berjumlah 10 buah titik. Variabel kerentanan pantai yang diamati yaitu geomorfologi, akresi/abrasi, kemiringan pantai, tinggi pasang maksimal, dan tinggi gelombang maksimal. Data yang diperoleh selanjutnya dikaitkan dengan informasi tentang ikan Sidat dan udang Vannamei. Sistem Informasi Geografi digunakan dalam penelitian ini untuk mengobservasi, menganalisa dan mengolah citra untuk mengetahui terjadi abrasi atau akresi. Hasil penelitian menunjukan bahwa pantai Kabupaten Purworejo memiliki nilai CVI dalam kategori tinggi dengan nilai tertinggi 4,7 dan terendah 4,3, dimana variabel dengan bobot yang berpengaruh terbesar adalah variabel tinggi gelombang maksimal. Kerentanan sumberdaya perikanan akibat kerusakan pantai dan muara dapat menyebabkan hilangnya ikan Sidat Anguilla bicolor dengan nilai estimasi produksi elver grade B mencapai Rp. 35.000.000/tahun dan budidaya udang Vannamei ( Litopenaeus vannamei ) dengan estimasi nilai ekonomi Rp. 315.000.000 /panen/tambak.

The coastal area character ized by black sand and high sea-waves, that makes it vulnerable as hydrodynamics of the southern Indonesia coast. The study aims to determine the value of coastal vulnerability index and to know the economic value and species diversity of fishery resources at the Purworejo district coastal area . The research was conducted on 2 nd February until 28 th October 2015 using the CVI (Coastal Vulnerability Index) methods that be modified in accordance to the location and research objects. Data were collected at t he observation’s sites amounts to 10 spots.
