Abstract
Kebutuhan energi meningkat dan Ketersediaan sumber daya fosil semakin menipis. Energi terbarukan menjadi alternatif berkelanjutan. Energi angin memiliki potensi besar tetapi pemanfaatannya di Indonesia masih terbatas akibat kecepatan angin rendah. Inovasi desain turbin angin diperlukan untuk meningkatkan efisiensi dalam kondisi angin lemah. Deflektor pada turbin angin Savonius menjadi salah satu solusi. Penelitian ini menganalisis pengaruh deflektor terhadap kinerja turbin melalui optimalisasi aliran angin.
Pengujian dilakukan pada turbin dengan variasi sudut deflektor. Variasi sudut meliputi α = 0° serta β = 50°, 60°, 70°, 80°, dan 90°. Kecepatan angin yang digunakan 5 m/s dan 7 m/s. Evaluasi kinerja turbin berdasarkan koefisiens daya (Cop), koefisien momen (Cm), torsi statis, dan torsi dinamis. Pengukuran torsi statis menggunakan torquemeter pada berbagai sudut azimuth (0º-180º). Pengujian torsi dinamis menggunakan brake dynamometer dengan variasi beban.
Penelitian ini menghasilkan pemahaman mengenai efek deflektor terhadap koefisien daya dan koefisien momen. Posisi deflektor di depan sudu advancing dan sudu returning menjadi faktor utama dalam analisis. Kesimpulan hasil menunjukkan bahwa konfigurasi sudut α = 0° dan β = 60° memberikan performa paling optimal pada kecepatan angin 5 m/s, dengan nilai Cop mencapai 0,1, Cm sebesar 0,26, dan CTS sebesar 0,14. Sebaliknya, performa terendah terjadi pada konfigurasi β = 90° dengan nilai Cop hanya 0,05 dan Cm sebesar 0,17. Pada kecepatan 7 m/s, konfigurasi β = 60° tetap menghasilkan nilai CTS tertinggi sebesar 0,1, meskipun nilai Cop dan Cm menurun menjadi masing-masing 0,08 dan 0,18. Konfigurasi terburuk pada kecepatan 7 m/s terjadi pada β = 90°, dengan nilai Cop sebesar 0,04 dan Cm sebesar 0,17, lebih rendah dari konfigurasi tanpa deflektor. Hasil penelitian mendukung optimalisasi desain turbin angin Savonius untuk meningkatkan pemanfaatan energi angin di Indonesia.

Energy demand is increasing, and fossil fuel resources are becoming increasingly scarce. Renewable energy serves as a sustainable alternative. Wind energy holds significant potential, but its utilization in Indonesia remains limited due to low wind speeds. Innovations in wind turbine design are necessary to enhance efficiency under low wind conditions. Deflectors on Savonius wind turbines offer a possible solution. This study analyzes the impact of deflectors on turbine performance by optimizing airflow interaction.
Turbine testing was conducted with various deflector angles. Variations included α = 0° and β = 50°, 60°, 70°, 80°, and 90°, respectively. Wind speeds of 5 m/s and 7 m/s were used. Performance evaluation was based on the power coefficient (Cop), moment coefficient (Cm), static torque, and dynamic torque. Static torque measurements were taken using a torquemeter at different azimuth angles (0º–180º). Dynamic torque testing was performed using a brake dynamometer with varying loads.
This study provides insights into the effects of deflectors on power and moment coefficients. The position of the deflector in front of the advancing and returning blades plays a key role in the analysis. The conclusion of the results indicates that the configuration with α = 0° and β = 60° delivers the best performance at a wind speed of 5 m/s, achieving a Cop of 0.1, a Cm of 0.26, and a CTS of 0.14. In contrast, the lowest performance at this speed was observed at β = 90°, with a Cop of only 0.05 and a Cm of 0.17. At 7 m/s, the β = 60° configuration still produced the highest CTS at 0.10, although the Cop and Cm decreased to 0.08 and 0.18, respectively. The worst performance at 7 m/s was recorded at β = 90°, with a Cop of 0.04 and a Cm of 0.17, both lower than the conventional setup. These findings support the optimization of Savonius wind turbine designs to enhance wind energy utilization in Indonesia.
