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.

Abstract

The primary objective of this study is to investigate how different sizes of drive pulleys influence the performance of an electric motorcycle equipped with a BLDC motor. This was approached using an experimental technique that combined dynotesting and road testing where three drive pulley diameters of 42T, 44T, and 46T were used. While the road tests were intended to measure the top speed of the motorcycle, the dynotests were aimed at acquiring the necessary data to calculate the torque and power. Based on the results of this study, an increase in the drive pulley's diameter will increase the speed of the electric motorcycle, although it will lower the torque. It was found that the 42T drive pulley offers the greatest torque, which is 16.54 Nm at a power of 5.2 HP, and the 46T drive pulley allows for the greatest speed of 63.37 km/h. It is thus apparent that for performance to be properly tailored to the motorcycle, a balance should be struck in line with the intended purpose, which can either be acceleration or the cruising speed.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kompetensi guru dan siswa SMK YP 17-1 Madiun dalam memahami Engine Management System (EMS) dan penggunaan scan tool sebagai alat diagnosis kendaraan modern. Metode pelaksanaan meliputi sosialisasi, pelatihan teori dan praktik, penerapan teknologi, pendampingan, serta evaluasi melalui pretest dan posttest. Pelatihan diikuti oleh 20 siswa dan 4 guru dengan pendekatan learning by doing. Hasil kegiatan menunjukkan peningkatan kompetensi peserta, ditandai dengan kenaikan rata-rata nilai teori dari 56,33 menjadi 84,50 (±50%) dan nilai praktik dari 50,00 menjadi 77,50 (±55%). Selain itu, dilakukan penyerahan ThinkCar ThinkSafe OBD-II Bluetooth Vehicle Diagnostic Tool dan OBD-II Extension Cable sebagai media pembelajaran untuk mendukung keberlanjutan praktik di sekolah. Program ini terbukti efektif dalam meningkatkan kompetensi diagnosis kendaraan berbasis EMS dan mendukung kesiapan lulusan sesuai kebutuhan dunia usaha dan dunia industri (DUDI).
