Studi Komparasi Hasil Pengolahan Pasang Surut Dengan 3 Metode (Admiralty, Least Square Dan Fast Fourier Transform) Di Pelabuhan Malahayati, Banda Aceh

Abstract: Pelabuhan Malahayati menjadi alur lintas serta tempat sandar bagi peti kemas domestik. Untuk menjalankan aktifitas pelabuhan secara optimal serta merencanakan pembangunan pelabuhan, pengetahuan mengenai tipe dan karakteristik pasang surut sangat penting. Pengolahan data pasang surut dengan berbagai metode dapat memberikan hasil yang berbeda-beda. Tujuan penelitian ini adalah untuk mengetahui karakteristik pasang surut dan komponen harmonik pembangkit pada lokasi penelitian, mengetahui perbandingan hasil pengol… Show more

“…This harmonic method is commonly used to calculate two harmonic constants, namely the amplitude and phase difference in a short time span [28]. Based on the calculation results, the tidal type of the model results and tidal predictions with FES2014 harmonic components, the Form Factor are 2.1 and 3.5, respectively, which make the tidal type is mixed tide predominantly diurnal diurnal [29]. This indicates that the waters around the mouth of the Citarum River, namely Jakarta Bay, have mixed tidal types that are predominantly diurnal.…”

“…Data from tidal observations for 3 days was processed using the admiralty method. The Admiralty method is one of the harmonic methods to calculate Amplitude and the difference of phase data in a short time range [17]. This data processing uses Microsoft Excel, which has been programmed in such a way that 3 days of data modelling can be carried out for up to a month in the Sembulang Waters, as shown in Figure 5, observing tidal conditions for 3 days (15-17 March 2021) in Sembulang Waters, Riau Islands has the highest tide value of 4.6 meters, the lowest low tide value of -0.8 meters, and MSL (Mean Sea Level) obtained by 1.61 meters.…”

“…The tidal component includes A as amplitude values and gas phase. The formzhal value can be worked out when the amplitude values of K 1 , O 1 , M 2 , and S 2 [17]. The determination of the tidal pattern was carried out using the tidal components that have been obtained.…”

“…Dalam analisis harmonik klasik, sinyal pasang surut dimodelkan sebagai jumlah dari himpunan berhingga sinusoidal pada frekuensi tertentu yang berkaitan dengan parameter astronomi. Serangkaian program telah ditulis dalam MatLab untuk (a) melakukan analisis harmonik klasik untuk periode sekitar 1 tahun atau lebih pendek, (b) memperhitungkan (beberapa) konstituen yang belum terselesaikan menggunakan koreksi nodal, dan (c) menghitung interval kepercayaan untuk analisis komponen tersebut (Ichsari et al, 2020;Pawlowicz et al, 2002) . Konstanta pasang surut yang terbentuk karena adanya distorsi non-linear dari osilasi konstanta pasang surut utama (contohnya M2, S2, dan K1) pada saat berinteraksi dan merambat di perairan dangkal.…”

“…Alat pengukuran arus yang digunakan adalah Current Meter Valeport 106 yang di deploy di kedalaman 5 meter pada kedalaman laut 12 meter. Pengolahan data untuk memperoleh komponen harmonik mengunakan Toolbox T-Tide berbasiskan bahasa pemrograman MatLab (Ichsari et al, 2020;Pawlowicz et al, 2002). Metode ini juga telah digunakan oleh penelitian sebelumnya yaitu Abida et al, 2015;Theoyana et…”
