[ABSTRAK
Regional Ocean Modeling System (ROMS) merupakan salah satu jenis pemodelanyang dapat digunakan untuk memodelkan pasang surut pada wilayah regionalyang relatif luas. Tesis ini melakukan studi tentang pemodelan pasang surutmenggunakan ROMS untuk wilayah Indonesia dengan membagi menjadi 4 zona.Data yang digunakan adalah data konstanta pasang surut dari TPXO tahun 2007(TPXO7), data batimetri resolusi 1 menit dari etopo serta data dari World OceanAtlas Tahun 2009 (WOA09) berupa data temperatur, salinitas, serta densitas darikedalaman 0 hingga 5500 meter. Sebagai validator digunakan data pengamatanpasang surut tahun 2013 dari stasiun pasang surut permanen milik BadanInformasi Geospasial. Hasil pemodelan ini memiliki akurasi dan tingkatkepercayaan yang baik untuk hampir di seluruh wilayah perairan NKRI dengannilai RMSE antara 9.4 cm hingga 24.4 cm namun hasil yang kurang baik didapatpada perairan sekitar Merauke, Papua dengan nilai RMSE 62 cm.
ABSTRACT
Regional Ocean Modeling System (ROMS) is one of the models that can be usedto simulate tidal regionally on relatively wide range area. Tidal modeling usingROMS in this thesis were performed by dividing Indonesian region into 4different zones. Harmonic constituent data from TPXO year 2007 (TPXO7),Bathymetry data with 1 minute resolution from etopo, and World Ocean Atlasdata year 2009 such as; temperature, salinity, inner density depth of 0 ? 5500meters were used as the model?s inputs. As the validators, Badan InformasiGeospasial?s tidal observation data year 2013 from permanent tidal gauge stationswere used. The modeling result shows good accuracy and reliability in almost allIndonesian water with RMSE between 9.4 ? 24.4 cm. However, bigger RMSE upto 62 centimeters were found in Merauke water, Papua.;Regional Ocean Modeling System (ROMS) is one of the models that can be usedto simulate tidal regionally on relatively wide range area.
