Abstract
Jawa Timur mempunyai 2 perairan dengan karakteristik yang berbeda. Berkebalikan dengan perairan utara Jawa Timur, Perairan Selatan Jawa Timur memiliki karakteristik tipe topografi yang curam, gelombang besar, dan berbatasan langsung dengan Samudra Hidia yang sifatnya unik karena dipengaruhi oleh angin musim dan angin pasat. Data gelombang sangat diperlukan untuk keperluan pelayaran, tata letak pelabuhan, perencanaan bangunan pantai dan lain sebagainya. Informasi kelautan masih sangat terbatas karena biaya pengukuran tinggi gelombang yang mahal. Maka diperlukan data alternative untuk menggantikan data dari pengukuran di lapangan. Untuk itu diperlukan validasi dari data gelombang satelit dengan data gelombang dari pengukuran lapangan. Oleh karena pada Tugas akhir ini penulis menganalisis perbandingan data dari ERA5 ECMWF dan data BMKG dengan data pengukuran lapangan untuk dianalisis tingkat hubungan korelasinya. Dari analisis tingkat hubungan didapatkan nilai koefisien sebesar 0.65 dimana kriteria hubungan dari kedua data kuat, dan mengindikasi bahwa data ERA5 ECMWF dapat digunakan sebagai keperluan perencanaan pantai. Setelah mendapatkan hasil korelasi dilakukan validasi dari data ERA5 ECMWF dengan data pengukuran lapangan yang diamati di daerah Banyuwangi. Dalam perhitungan tinggi gelombang periode ulang didapatkan tinggi gelombang 100 tahun menggunakan 3 metode, yaitu Gumbel, Log Normal dan Log Pearson III di Perairan Selatan Jawa Timur masing-masing sebesar 0.944 m – 1.332 m; 0.94 m – 1.236 m; dan 0.944 m – 1.258 m.
================================================================================================
East Java has 2 waters with different characteristics. In contrast to the northern waters of East Java, the southern waters of East Java have the characteristics of a steep topography, large waves, and are directly adjacent to the Indian Ocean, which are unique because they are influenced by monsoons and trade winds. Wave data is needed for shipping purposes, port layout, coastal building planning and so on. Marine information is still very limited due to the high cost of measuring wave height. So alternative data is needed to replace data from measurements in the field. For this reason, it is necessary to validate the satellite wave data with wave data from field measurements. Therefore, in this final project, the author analyzes the comparison of data from ERA5 ECMWF and BMKG data with field measurement data to analyze the level of correlation. From the analysis of the relationship level, the coefficient value is 0.65 where the relationship criteria from the two data are strong, and indicates that the ERA5 ECMWF data can be used for coastal planning purposes. After getting the correlation results, validation of the ERA5 ECMWF data was carried out with field measurement data observed in the Banyuwangi area. In calculating the wave height of the return period, the wave height of 100 years was obtained using 3 methods, namely Gumbel, Log Normal and Log Pearson III in the Southern Waters of East Java, respectively 0.944 m – 1.332 m; 0.94 m – 1,236 m; and 0.944 m – 1,258 m.
