Abstract
Pasang surut air laut bersifat periodik terhadap waktu (harmonik) sehingga pergerakan gelombang pasang surut air laut dapat dimodelkan menggunakan persamaan sinusoidal. Pengamatan pasang surut air laut dapat dimodelkan dengan beberapa jenis berdasarkan sumber datanya yaitu menggunakan data stasiun pasang surut permanen (hydrodynamic model), satelit altimetry (empirical model), dan kombinasi (asimilasi model). Secara global model pasang surut air laut di dunia sudah dimodelkan menggunakan beberapa jenis model, namun masih belum dapat diputuskan model yang paling sesuai di seluruh daerah. Kompleksnya perairan di Indonesia menjadi hal penting untuk mengkaji mengenai pemodelan pasang surut air laut yang sesuai di Perairan Indonesia. Kelanjutan pemodelan pasang surut secara global merupakan hal penting untuk meningkatkan keakuratan pemodelan di setiap daerah. Pada penelitian ini, dilakukan perhitungan nilai simpangan data model GOT terhadap data pasang surut air laut lokal (referensi) yang tersebar di 38 titik di Perairan Indonesia menggunakan metode statistika. Hasil dari penelitian ini diperoleh besar ketidaksesuaian (%) model GOT yaitu FES2014 sebesar 1,322%, TPXO9 sebesar 1,060%, dan EOT11a sebesar 0,961%. Perairan Indonesia dengan jenis perairan terbuka lebih memiliki kesesuaian yang kuat dengan model GOT jenis empirical, sedangkan untuk perairan dangkal kesesuaian yang kuat pada model asimilasi, namun untuk pemodelan empirical tidak begitu jauh perbedaannya. =================================================================================================================================
Ocean tide is rising and falling of the water level to periodic time (harmonic), their movement can be modeled by sinusoidal equation. Ocean tides observation being modeled using several methods, they are tide gauges (hidrodinamic model), altimetry (empirical model), and combinations (asimilasi model). Overall, ocean tide model has been modeled using several types of models, but it hard to determined which model will be best fit for all regions. The complexity of Indonesia oceans is an important thing to be learn for better globsl ocean tide model moreover for accurate ocean modelling. In this research, calculation of Root Mean Square value of GOT data against reference using statistical method. The result show incompability (D%)for GOT to FES2014 is 1,322%, to TPXO9 is 1,060%, and EOT11a is 0,961%. Indonesia ocean with open seas types are more suitable for the empirical model of GOT, whereas for shallow area there is strong compatibility with assimilation model of GOT.
