Abstract: MOTIWALI is a water level instrument based on acoustic that has been created at the Marine Instrumentation Laboratory of ITK-IPB. The data recording need detail analyze by a program to detemine constituent of tide characteristicc. The objective this study is developing interface program (software) for tidal analisys with Admiralty methode. This Admiralty-based method program computes 9 tidal constituents, determines Formzahl tidal types, and predicts tidal time-series for particular time-length. The Matlab-based program scripts consist of four modules: the pre-processing module for parsing, filtering and data averaging; the Admiralty module for tidal constituents analysis, the Formzahl module for tidal types determination; and prediction module for tidal prediction. The 15-day sea-surface elevation time series data from Pramuka Island - Seribu Islands Jakarta have been used to examine the performance of the software. The result shows that the amplitude and phase difference obtained from this software and Dishidros tidal table (also with least-squared t-tide method) was very small (RMSE: 1.89 cm and 102°). This means that accuracy of calculation are quite consistent. Furthermore, diurnal tidal type (Formzahl number, F=4.43) obtained from this analysis was in good agreement with previous studies. Tidal prediction module provides beneficial information for marine activities around the region.
