Abstract
Penelitian ini merupakan pengembangan Co-Tidal Charts di Laut Jawa untuk mendapatkan gambaran perambatan pasang surut di area tersebut. Data prediksi pasang surut dihitung dengan analisa harmonik dari dua puluh stasiun pengamatan pasut yang tersebar di perairan Laut Jawa dan digunakan untuk membuat Co-Tidal Charts tersebut. Konstanta harmonik pasut diolah menggunakan metode least square. Pada penelitian ini menggunakan lima konstanta harmonik yang digunakan untuk membentuk Co-Tidal Charts yaitu M2, N2, S2, K1 dan O1. Co-Tidal Charts yang diperoleh menunjukkan gambaran secara umum karakteristik pasang surut di perairan Laut Jawa termasuk area persebaran tipe pasut dan arah rambatan pasut. Berdasarkan penelitian ini arah rambatan gelombang pasut Laut Jawa berasal dari Samudera Hindia dan Laut China Selatan melalui Selat Karimata yang bertemu di tengah Laut Jawa. Perairan Laut Jawa pada bagian Barat dan Tengah didominasi oleh komponen pasut harian (diurnal) dan bagian Timur didominasi komponen pasut setengah harian (semidiurnal). Kondisi tersebut yang mempengaruhi variasi tipe pasut di perairan Laut Jawa.
============================================================
This research developed co-tidal charts of Java Sea in order to get the simulation of the tidal propagation in this area. The tide predictions data calculated from the harmonic analysis of tide observation in 20 tidal stations across Java Sea were used to build the co-tidal charts. The harmonic constituents of the tide were extracted using least squares method. There are five harmonic constituents used to establish the co-tidal chart: M2, N2, S2, K1 and O1. The obtained co-tidal charts indicate the main characteristics of the tides in the Java Sea region include the areas of amplification and main propagation directions. Based on this research the directions are affected by the tide propagation from the South China Sea and Indian Ocean towards the middle of the Java Sea. These contribute to the variation of the tide types across the Java Sea.
