Abstract
Ketersediaan sumber energi merupakan salah satu aspek yang menentukan pergerakan aktivitas manusia di era saat ini. Hingga saat ini, umat manusia masih mengandalkan sumber energi yang berasal dari fosil, salah satu contoh dari sumber energi fosil adalah minyak bumi. Akhir-akhir ini, para ahli sedang berlomba untuk menciptakan dan mengembangkan berbagai jenis sumber energi terbarukan yang dapat dimanfaatkan. Salah satu potensi energi besar yang dapat dikembangkan di Indonesia adalah energi arus laut. Salah satu sistem yang menggunakan energi arus laut adalah turbin air. Hingga saat ini sudah banyak yang mengembangkan turbin Savonius tipe vertikal karena memiliki kelebihan yaitu dapat beroperasi dalam arus berkecepatan rendah. Namun, untuk turbin Savonius tipe cross-flow masih belum banyak dikembangkan. Penambahan deflektor aliran mempengaruhi performa turbin karena aliran air yang mengarah pada returning blade dibelokkan dan memperkuat aliran pada advancing blade. Analisis dilakukan dengan pendekatan Computational Fluid Dynamics (CFD) menggunakan software Ansys Fluent. Hasil penelitian menunjukkan rata-rata peningkatan performa sebesar 12%, dengan konfigurasi paling baik berada pada deflektor dengan sudut 42° pada TSR 0,74 yaitu sebesar 0,299

The availability of energy sources is one of the aspects that determines the movement of human activities in this era. Until now, mankind still relies on energy sources that come from fossils, for example of fossil energy sources is petroleum. Lately, experts are competing to create and develop various types of renewable energy sources that can be utilized. One of the great energy potentials that can be developed in Indonesia is ocean current energy. One system that uses ocean current energy is a water turbine. Until now, many researchers have developed the vertical type Savonius turbine because of the advantage that it can operate in low-speed currents. However, the cross-flow type Savonius turbine has not that much developed. The addition of a flow deflector affects the performance of the turbine because the flow of water that leads to the returning blade is deflected and strengthens the flow of the advancing blade. The analysis was carried out using a Computational Fluid Dynamics (CFD) approach using the Ansys Fluent software. The results showed an average performance increase of 12%, with the best configuration on a deflector with an angle of 42° at a TSR of 0.74, which was 0.299
