<p align= "justify">The study of ocean tide is important in several things for both technical and scientific purposes in marine areas, example for the purpose of developing ports in coastal areas or offshore drilling. Measurement of ocean tides with Altimetry satellites is more effective than tide gauge because can measure tidal in the open sea and cover a larger area whereas tidal gauge are localized, difficult to observe in open sea area and still influenced by deformation effects. This research aims to model the ocean tides in Indonesian waters so that later can be obtained general characteristics and type of tide in Indonesian waters that can be understood by people that concerned in the field of marine geodesy, oceanography, hydrography and other. The data used in this research are Sea Surface Height (SSH) from Altimetry satellites during 1992-2017 (period of 9.9156 days) and total of footprint is 13815 points. Estimation method of the amplitude and phase of each tidal constituent used the harmonic analysis with nodal correction and aliasing frequency. Overall, validation results (RMS deviation values) between estimation results with TPXO7.2 and FES2014 global tide models are quite small from 0-3 cm (amplitude) and for phase is quite big from 50-200 degrees (phase). The modeling results show that the type of tide in Indonesia is dominated by mixed semi diurnal, mixed diurnal and diurnal, and from the tidal prediction results also show the lowest and highest level value is ±3.5 meters above and below the reference field. Based on the result of co-range and co-phase of each tidal component, the high amplitude value in Indonesian waters are components M2, S2, K1 and O1. The highest value on thirteen tidal constituent are the Arafura Sea, the Timor Sea and the Celebes Sea. Value of HAT and LAT in Indonesian water is varies from 0-360 cm above and below the Mean Sea Level (MSL).<p align= "justify">
