In this final project has been studied tidal condition in South East Asian Seas and Eastern part of Indian Ocean, that lies in between 90° to 150° East Longitude and 20° <br /> <br /> North Latitude to 40° South Latitude using altimetry satellite data (20 years; 18th August 1994 – 18th December 2014). Objectives of this study are to obtain a spatial distribution of amplitude and phase, and make co-range and co-phase to investigate tidal dynamic of each constituent (M2, S2, N2, K2, K1, O1, and P1) in this waters. The results have been compared with simulation results by Tide Model Driver (TMD), and with previous studies namely <br /> <br /> Ali (1992), Mihardja (1991), Wyrtki (1961), Ray, et.al (2005), Perbani (2002), Schwiderski (1979), Hatayama (1996), and Pariwono (1989). The results show that tides in the eastern part of Indian Ocean propagate to east to <br /> <br /> Timor Sea and till Australian Northern Coastal Waters. Tidal amplitude are increasing toward coastal waters and ranging from 0.1 m to 2 m. Tidal wave in the eastern Indonesian waters (Banda and Arafura Seas) are coming from the eastern part of Indian Ocean through Timor Sea with semidiurnal constituent amplitude ranging from 0.1 to 0.6 m and diurnal constituent ranging from 0.1 to 1.1 m. Whereas tidal wave in the western Indonesian waters (Flores Sea, the Makassar Strait and Java Sea) are coming from the Pacific Ocean, with amplitudes ranging from 0.1 to 0.8 m, except tide in the Malacca Strait that come <br /> <br /> from the Indian Ocean. Tide in the South China Sea are co-oscillating wave with tide in Pacific Ocean propagate through Luzon Strait to the south of this sea till Karimata Strait and the Gulf of Thailand which its amplitudes are ranging from 0.1 to 0.8 m. Tide in the Northern Australia Coastal Waters and Malacca Strait have semidiurnal type, meanwhile tidal type in the eastern part of Indian Ocean, Banda Sea, Makassar Strait, and middle part of Java Sea is mixed predominantly semidiurnal. While the type in the Arafura Sea, eastern and western part of Java Sea, Karimata Strait, southern part of South China Sea, and Gulf of Thailand is diurnal, and the northern and middle part of South China Sea is mixed predominantly diurnal. Tidal constituent analysis using altimetry <br /> <br /> satellite data show that amplitude of each constituent are corresponding results with other studies, but for phase component are still considerable difference. Nevertheless the results have been able to describe the general pattern of tidal propagation as good as other studies.
