In this article is conducted research to harness wind energy which is generated by a truck that is running on the public road and highway. To take advantage of wind energy of the moving truck is designed a axial movable wind turbine in accordance with the size of the current truck. The purpose of this research is to construct and testing the performance of the designed axial movable wind turbine which is based on the optimum blades size. Number of the blades are six pieces and diameter of the blades are 0.35 m. To test the wind turbine that have been assembled, it is used loads on the wind turbine, respectively, 8 watts and 25 watts. The wind turbine that will be tested is installed on a mini truck. Furthermore, the mini truck runs at speeds up to 80 km/h. This research has succeeded to design and testing a prototype of axial movable wind turbine and the designed wind turbine can resulted electrical energy about 3.5 watts with the load 25 watt bulb. The designed axial movable wind turbine can be installed in the truck by further improving some components of the resulted prototype of the axial movable wind turbine.

Abstract

Masjid Al-Mansyah di Desa Karang Anyar, Kecamatan Beringin, Kabupaten Deli Serdang mengalami permasalahan kualitas air bersih yang digunakan untuk kebutuhan wudu dan kebersihan lingkungan masjid. Air yang berasal dari sumber air tanah memiliki karakteristik payau, keruh, berwarna kecokelatan, serta menghasilkan endapan setelah didiamkan sehingga mengurangi kenyamanan jamaah dan mempercepat terbentuknya kerak pada fasilitas sanitasi masjid. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kualitas air bersih melalui penerapan sistem filtrasi menggunakan tabung Fiber Reinforced Plastic (FRP) yang diisi media filtrasi sesuai karakteristik air baku. Metode pelaksanaan meliputi survei dan identifikasi permasalahan mitra, perancangan sistem filtrasi, pengadaan material, instalasi unit filter beserta modifikasi perpipaan, penyuluhan mengenai pengoperasian dan perawatan filter, serta pendampingan pascaimplementasi. Hasil kegiatan menunjukkan bahwa sistem filtrasi berhasil menghasilkan air yang lebih jernih, tidak berbau, tidak berasa, serta mengurangi endapan yang sebelumnya muncul setelah air didiamkan. Peningkatan kualitas air tersebut memberikan dampak positif terhadap kenyamanan jamaah dalam melaksanakan wudu dan mendukung kebersihan fasilitas Masjid Al-Mansyah. Program ini juga meningkatkan pemahaman pengurus masjid mengenai pengoperasian dan pemeliharaan sistem filtrasi sehingga keberlanjutan pemanfaatan teknologi dapat terjaga.

Abstract

Dusun 2 Titi Payung adalah salah satu dusun yang terletak di Desa Naga Timbul kecamatan Tanjung Morawa Deli serdang terletak di dekat areal perkebunan PT. PP Lonsum, terletak 30,5 km dari kota medan. Dusun ini  dihuni oleh 35 KK dengan jumlah anak usia sekolah sekitar 50 orang. Dusun ini baru mendapatkan pasokan Listrik dari PLN pada tahun 2020. Umumnya penduduk di dusun 2 Titi Payung berprofesi sebagai petani, sebagian lagi sebagai peternak dan buruh pada Perkebunan yang ada di sekitar dusun tersebut. Untuk ternak biasanya yang dipelihara adalah sapi, kambing dan ayam. Salah satu calon mitra pengabdian, Bapak Poniran NR menggantungkan hidupnya dari usaha peternakan kambing. Pekerjaan ini ditekuninya sejak tahun 2005 dengan jumlah kambing yang diternakkan saat ini sejumlah 45 ekor. Untuk mendapatkan pakan bagi ternaknya, biasanya Bapak Poniran NR membawa ternaknya ke Lokasi sekitar perumahan penduduk dan Perkebunan sawit untuk diangon di sana. Baru pada sore hari kambing-kambingnya dibawa pulang kembali ke kandang. Hal ini terus-menerus dalam waktu yang relatif lama dilakukannya mengingat keterbatasan areal di sekitar pemukiman penduduk yang dapat ditanami rumput gajah maupun hijauan yang diperlukan ternak kambingnya. Ada tanaman lain yang bisa dimanfaatkan sebagai pakan tetapi perlu pencacahan.

Abstract

Poultry animals such as chickens incubate their eggs in three weeks to hatch their eggs, which sometimes the egg yields are not optimal so that a poultry egg incubator and its system are needed to optimize the results of hatching in which this built-in incubator with a capacity of 300 eggs with a rack system that rotates automatically based on Arduino Uno, using a digital temperature and hygrometer sensor so that the temperature can be set at 38-39 0C and the humidity can be set at 55-70% according to the egg hatching temperature and humidity, and from the test results obtained, the number of eggs that do not hatch and hatch both that hatch normally, defective, and die, the research conducted, for chicken eggs, which originally amounted to 300 eggs to be hatched, 291 eggs that hatched well, 5 defective eggs, and 3 eggs that died and 1 egg that does not have any embryos, and the result that this chicken egg incubator machine is capable of hatching eggs 97%.

Abstract

The increasing demand for sustainable energy solutions has encouraged the development of renewable energy technologies that can be integrated into various applications, including transportation systems. Wind energy generated from vehicle-induced airflow represents an alternative energy source that remains underutilized due to complex aerodynamic characteristics and unstable flow conditions. This study aimed to optimize the aerodynamic performance of vehicle-mounted axial wind turbine blades by determining the most suitable angle of attack using Computational Fluid Dynamics (CFD) simulations. The research method involved numerical analysis using CFD software to evaluate the aerodynamic behavior of turbine blades under different angle-of-attack variations of 0°, 5°, 10°, 15°, and 20°. Performance evaluation was conducted based on the lift-to-drag ratio and velocity contour distribution to identify the optimal blade configuration. The results showed that the angle of attack significantly affected aerodynamic performance, with the 10° configuration producing the highest lift-to-drag ratio and the most favorable airflow characteristics. Higher angles of attack resulted in increased flow separation and aerodynamic losses, whereas lower angles produced insufficient lift generation. The optimized turbine design consisted of six blades with a rotor diameter of 0.35 m, demonstrating the potential application of vehicle-induced airflow energy harvesting systems. In conclusion, CFD-based optimization provided an effective approach for improving the performance of vehicle-mounted wind turbine blades and supported future development of renewable energy technologies for sustainable transportation applications.
