Abstract

The utilization of wind energy through vertical axis turbines such as Savonius Type-L is a promising solution for small-scale renewable energy, but the understanding of the effect of blade number variation on its performance is still limited. This study aims to experimentally analyze the performance of the L-type Savonius wind turbine by varying the number of blades (2, 4, and 6) in the wind speed range of 6, 7, and 8 m/s. Tests were conducted using a wind tunnel to measure key parameters such as rotational speed and torque under controlled conditions. The results showed a strong positive correlation, where an increase in wind speed consistently increased the rotational speed and torque across all blade configurations. Specifically, the 4-blade configuration showed the most superior performance, achieving the highest rotational speed and torque compared to other configurations at a wind speed of 8 m/s. This finding confirms that wind speed is a determinant factor in turbine performance and indicates that the 4-blade configuration is the optimal choice to maximize power extraction under the test conditions conducted. Keywords: Savonius, Turbine blade, Torque, Rotational Speed.

Abstract

Desa Bayu Urip merupakan salah satu desa yang berada di Kecamatan Ujung Pangkah, Kabupaten Gresik. Desa ini merupakan salah satu desa yang memiliki potensi karena wilayah dekat dengan laut, membuat mayoritas warga desa bekerja sebagai nelayan. Selain menangkap ikan, desa Bayuurip juga membudidayakan kerang hiaju sebagai penghasil laut.Desa ini menghasilkan kerang yang cukup tinggi sebagai hasil lautnya,berdampak banyak menghasilkan limbah cangkang kerang sebagai hasil sampingnya.Kegiatan pengabdian ini untuk memberikan solusi dalam mengurangi limbah, diperlukan suatu  mesin penghancur atau penggiling cangkang kerang hijau yang ramah lingkungan sehingga perlahan - lahan dapat mengurangi problem limbah tersebut serta target luaran pemahaman dan kesadaran masyarakat terhadap kesehatan meningkat. Metode pengabdian masyarakat ini membuat mesin penggiling cangkang kerang hijau yang terciptanya mesin sesuai kebutuhan.Mesin mesin penggiling memiliki penggerak Diesel Engine berdaya 6,5 HP dan memiliki kecepatan putar motor 3000 Rpm. Kapasitas produksi mesin ini yakni 60 kg/jam untuk menggiling atau menghancurkan cangkang kerang hijau. Rata-rata ukuran penggilingan yang didapatkan dari mesin yaitu 0-2 mm.

Abstract

Wind energy is a potential renewable energy source in Indonesia, but the relatively low wind speed requires efficient turbine technology. The Savonius turbine has become an alternative choice for generating electrical energy. This research aims to determine the performance of the Savonius type-S turbine with blade numbers of 3, 5, and 7 at different wind speeds. The method used was an experiment conducted in a laboratory-scale wind tunnel simulator, with testing conducted across three blade configurations at wind speeds of 6, 7, and 8 m/s. The research results show that the 3-blade turbine achieves optimal torque at all wind speeds, with a maximum of 0.24 Nm at 8 m/s. The maximum wind power is obtained with the 7-blade turbine, reaching 167 watts at 8 m/s. The optimal turbine power also occurs with the 3-blade configuration, with the highest value being 10.30 watts at 8 m/s. The highest turbine efficiency is achieved by the 7-blade turbine, which is 31.85% at 8 m/s. Based on these results, it is concluded that the number of blades affects the performance characteristics of the Savonius type-S turbine. The 3-blade configuration produces the best torque and turbine power, while the 7-blade configuration excels in wind power and efficiency.
