Abstract

Pembangkit listrik tenaga gelombang laut sangat memungkinkan untuk dikembangkan di Indonesia. Selain memiliki potensi wilayah perairan yang sangat luas, penelitian terkait pembangkit listrik tenaga gelombang laut juga sudah banyak dilakukan dan terus dikembangkan hingga saat ini. Sebagai langkah awal sebelum melakukan penelitian lebih lanjut, dibuatlah wave tank skala laboratorium sebagai media untuk mengamati karakteristik gelombang. Tinggi dan panjang gelombang merupakan salah satu parameter yang dijadikan tolak ukur dalam penelitian ini. Desain pembuat ombak tipe piston dengan ukuran tangki yang sudah ditentukan, yaitu panjang 150 cm, lebar 35 cm, dan tinggi 35 cm dibuat sedemikian hingga dengan menghitung beban mekanik. Metode penelitian yang digunakan ialah perancangan teknik. Hasil rancang bangun menghasilkan mesin wave tank model piston dengan ukuran rangka, yaitu panjang 155 cm, lebar 40 cm, dan tinggi 122 cm yang digunakan untuk menopang tangki, motor listrik, dan wavemaker. Jenis penggerak yang digunakan yaitu model piston dengan satu kecepatan putaran yang diatur oleh dimmer. Tinggi gelombang yang dihasilkan bervariasi mulai dari 1,1 cm – 2,5 cm sedangkan panjang gelombang yang dihasilkan bervariasi juga yaitu, 10,5 cm – 20,5 cm.

Abstract

Laboratory-scale wave tanks are widely used to investigate surface wave behavior using different types of wavemakers, including flap and piston configurations. Previous studies by the authors showed that a simple transmission mechanism for a piston wavemaker produced unstable piston motion, resulting in variations in wave height and wavelength. This study designed and experimentally evaluated a crankshaft transmission system to drive a piston-type wavemaker and obtain more controlled piston motion. The experimental evaluation included mechanical performance analysis in terms of generated force and torque and measurement of wave characteristics at different distances from the wave source. The crankshaft system generated a force of 12.11 N and a torque of 0.24 Nm. The generated waves had average heights of 0.033, 0.029, and 0.027 m at distances of 0.5, 0.7, and 0.9 m, respectively, while the average wavelengths were 0.346, 0.350, and 0.334 m. The decrease in wave height with distance indicates wave energy attenuation during propagation. Compared with the previous piston wavemaker using a simple transmission system, the crankshaft system increased average wave height by 63.02% and average wavelength by 104.34%. The results indicate that the crankshaft transmission provides a more consistent piston motion and wave generation for laboratory-scale wave tank applications.
