Abstrak

Kejadian pasang surut yang sering disebut pasut merupakan kejadian proses naik turunnya air laut secara periodik yang ditimbulkan adarrya gayatarik-menarik dari benda-benda angkasq yang terutama sekali disebabkan oleh gaya tarik matahari dan gaya tarik bulan terhadap massa air bumi. Gaya penggerak pasang surut yang rumit ini dapat diuraikan sebagai hasil gabungan sejumlah komponen harmonik pasut {harmonic constituerzfs). Doodson mengembangkan metode sederhana unfuk menenfukan komponen- komponen (constituents) utama pasang surut, Principal Lunsr (M2), Principal Solar (Sz), Large Lunar Elliptic (Nz), Lunar-Solar (K2), Luni Solar Diurnal (Kr), Principal Lunar Diurnal (Or), Principol Lunar Diurnal (Pr), Komponen Laut Dangkal (M+), dan Komponen Laut Dangkal (MS+), dengan menggunakan panjang data pengamatan pasang surut 15 dan 29 hari dengan pengamatan jam-jaman. Biasanya didalam menganalisis pasang surut, kebanyakan dad para peneliti menggwrakan 9 konstanta harmonik. Tetapi didalam studi ini, metode analysis spektrum dipergunakan untuk menghasilkan frekuensi pasang surut. Data pasang surut dari stasiun Tanjung Periok dipergunakan untuk mempelajari frekuensi harmonik pasang surut. Didalam analisis, panjang data 15 hari dan 30 hari dipergunakan. Dari hasil penelitian ditunjukkan bahwa komponen pasang surut dari stasiun tanjung periok mempunyai 7 komponen dominan untuk data 15 hari (Kl, ol, Pl ,h42, s2, N2, K2) dan 6 komponen dominan untuk data 30 hari (K1, 01, Pl, l:&dz,S2,Y\2>. Knta kunci : Pasang Surut, analysis spektum, Tanjung Priok (The tides are the process of ups and downs of seawater periodically posed the existence style athaction of celestial bodies, which most notably caused by gravitational forces of the Sun and the Moon pull style of water masses of the Earth. Tidal oscillations can be deseribed as a combined result of a number of components of the tide harmonics (harmonic constifuents). Doodson developed a simple method to determine the components (constituents), Principal Main of the Lunar tides (M2), the Principal Solar (S2), a Large Lunar Elliptic (N2), Lunar- Solar {Y.2), Luni Solar Diurnal (Kl), a Principal Lunar Diurnal (Ol), Principal Lunar Diurnal (P1), Shallow Sea Components (M4), and Shallow Sea Components (MS4), using tidal observations data length of 15 and 29 days with hourly observations. Commonly, in tide analysis, the most of researchers use I tide harmonic constituents. But in this study, spectral analysis method is used to generate tidal frequencies. Tide data from the station of Thnjung Periok is used to study frequencies of tide harmonics. In the analysis, data length of 15 (fifteen) days and thirfy (30) days are used. From the results are presented that tidal constituents from station of Timjung Priok having 7 dominant constituents for the data of 15 days (K1,01, Pl, M2,g:2,N2, K2) and 6 dominantconstituents forthe data of 30 days (K1, Ol, Pl ,M2, 52, K2). Keywords : tides, spectral analysis, Thnjung Priok)
