Abstract

Kawasan wisata Prigi adalah salah satu pantai yang terletak di wilayah Kabupaten Trenggalek . Pantainya memanjang kurang lebih 2 km, berpasir putih, dan memiliki ombak yang tenang. Lokasi kawasan wisata Prigi di tepi Samudera Indonesia yang berupa teluk Prigi memungkinkan kawasan wisata ini mengalami perubahan garis pantai akibat pengaruh angin/gelombang, arus, pasang surut dan bathimetri. Oleh sebab itu, maka diperlukan analisa morfologi untuk mengetahui ada tidaknya perubahan garis pantai dan alternatif penyelesain bila terjadi perubahan garis pantai. Dalam analisa morfologi Kawasan wisata Prigi, hal utama yang perlu diperhatikan adalah tersedianya data-data primer dan sekunder lokasi tinjauan. Data-data sekunder tersebut antara lain: data angin dan data hidro-oceanografi. Kemudian data tersebut dianalisis untuk mendapatkan gelombang dan perubahan garis pantai yang akan terjadi. Dalam analisa morfologi ini digunakan metode analitik dengan periode antara tahun 2010- 2014. Analisa morfologi yang dilakukan menggunakan program bantu CEDAS (Coastal Engineering Design & Analysis System) Versi 4.0. Berdasarkan hasil analisa tugas akhir ini didapatkan bahwa ujung pantai sebelah barat dan ujung pantai sebelah timur cenderung mengalami kemunduran. Sedangkan pantai bagian tengah cenderung mengalami sedimentasi. Alternatif penyelesaian yang digunakan untuk mengatasi masalah kemunduran pada ujung pantai adalah sand nourishment dengan jumlah pasir sebesar 25.000 m3/tahun =========================================================================================Prigi Beach is one of the beaches located in Trenggalek. Prigi beach extended approximately 2 kilometers, white sand and has calm waves. The location of Prigi Beach on the edge of the Indonesian ocean being a Prigi bay allows the tourist areas are changing coastline due to effects of wind/waves, currents, tides and bathymetry. Therefore, it is necessary morphological analysis to determine whether there is a change of coastline and an alternative solution in case of changing coastline In morphology analysis of Prigi Beach, the main thing to note is the availability of primary and secondary data on the location of reviews. Secondary data include: wind data and hidro-oceanography data. Then the data were analyzed to obtain the wave plan and coastline changes that will occur. In this morphology analysis is used an analytical method with periode range on the year 2010 – 2014. Morphological analyzes were performed using CEDAS (Coastal Engineering Design & Analysis System) Version 4.0 software. Based on the analysisof this final project in getting that end of the beach to the west and east end of the beach is erosion. While the central part of the beach tend to sedimentation. Alternatif solution is used to result the problem of erosion at the end of the beach is sand nourishment with sand supply amount of 25.000 m3/year
