Abstract
Penggunaan energi terbarukan yang ramah lingkungan tanpa emisi gas
buang telah banyak dikembangkan seperti pemanfaatan energi kinetik dari arus air
laut menjadi energi listrik dengan menggunakan turbin. Tipe turbin yang digunakan
antara lain adalah turbin sumbu vertikal Darrieus dan Savonius. Turbin Savonius
cocok digunakan untuk arus laut kecepatan rendah sendangkan turbin Darrieus
memiliki koefisien daya yang tinggi. Sehingga kombinasi kedua turbin ini akan
dipelajari. Penelitian ini menggunakan dua model turbin kombinasi Darrieus-
Savonius yakni model A dan model B. Untuk mengetahui kinerja turbin tersebut
dilakukan analisa Computatioanl Fluid Dynamics (CFD) dengan menggunakan
software ANSYS Fluent. Data kecepatan arus diambil dari kecepatan rata-rata
perairan di sebelah barat Pulau Giliyang-Madura, selama 2 tahun (2014-2015)
yakni 0,269 m/s. Hasil perhitungan CFD menunjukkan turbin kombinasi model B
menghasilkan koefisien daya maksimum sebesar 0,256 pada tip speed ratio 1,6 dan
memiliki kinerja 34% lebih baik dari turbin Savonius

Using clean energy and without gas emission has been developed now day.
Such as using kinetic energy from marine current with marine turbine. Kind of
turbine is Darrieus and Savonius vertical Turbine. Savonius turbine suitable for the
characteristics of ocean currents at low speed, while Darrieus Turbine has high
power coefficient. So the combination of the two turbine is studied. This study uses
two model of combination Darrieus Savonius turbine namely the model A and the
model B. CFD simulation using software ANSYS Fluent carried out to know
performance of Darrieus – Savonius turbine. The average speed of ocean current is
obtained from the sea at Giliyang, Madura Island for 2 years (2014-2015) that is
0.269 m/s. The results of the CFD calculations show that the combination of turbine
model B generate the peak power coefficient 0.256 at tip speed ratio 1.6 and has
34% performance better than the turbine Savonius
