Abstract

Natural frequency is one of the factors in bridge construction. Because the natural frequency can be used as an indicator to detect the ability of the bridge, including the ability to withstand resonance. In addition, the natural frequency is also a way to analyze damage that will or has already occurred to a bridge. One of the analytical methods that can be used to analyze natural frequency values is the Undamped-Degree of Freedom. The results of this study indicate that the natural frequency value of the Sei Wampu Bridge has a value of 10.97 rad/s for the first mode, 18.06 rad/sec for the second ,mode and 20.34 rad/sec for the third mode. From the results of this analysis, it can be seen that the natural frequency value will increase as the bridge mode increases.

Abstract

Oscillating Water Column adalah jenis konverter energi gelombang yang memanfaatkan gerakan naik turun kolom air internalnya akibat beban dinamik gelombang laut. Ada dua jenis model yang dibahas dalam studi ini, yaitu bentuk konvensional (L-OWC) dan U-OWC. Simulasi numerik untuk kedua model OWC tersebut menggunakan Computational Fluid Dynamics dan OpenFOAM solver. Perbandingan hasil elevasi muka air teoritis dengan tangki gelombang numerik melalui solver tersebut membuktikan validitas pemodelan numeriknya. Studi ini menemukan bahwa model L-OWC memiliki performa yang lebih baik dari segi nilai RAO dan efisiensi hidrodinamisnya. Namun, bentuk kolom air tidak terlalu mempengaruhi koefisien refleksi dalam kondisi resonansi. Simulasi numerik kedua model OWC untuk kondisi perairan laut Belawan juga telah dilakukan dan mengindikasikan hal yang sama. L-OWC memperoleh nilai efisiensi hidrodinamik sebesar 81.97% sedangkan U-OWC bernilai 10.8%.
