Abstract

Bendungan Menaming berada di Desa Menaming terpisah sekitar 3 km dari pemukiman penduduk sehingga jauh dari jangkauan penyedia layanan listrik. Air dari bendungan didistribusikan melalui saluran irigasi ke persawahan dan perikanan warga mengandung banyak daya hidrolis. Kegiatan pengabdian masyarakat bertujuan untuk menyediakan kebutuhan daya listrik dengan mengembangkan pembangkit listrik pikohidro karena lokasi sedang dalam pengembangan untuk dijadikan kawasan wisata. Pemanfaatan sumber daya air pada saluran irigasi dapat dilakukan dengan mengembangkan kincir air sebagai penggerak generator listrik. Pembangkit listrik dengan penggerak kincir air aliran bawah sangat cocok dikembangkan karena pembuatan dan perawatannya mudah. Disamping itu struktur dan bentuk kincir air dapat menambah keindahan dan daya tarik bagi pengunjung lokasi wisata. Sekarang telah terpasang pembangkit listrik tenaga air dengan daya total sekitar 70 Watt. Listrik ditansmisikan menggunakan kabel melalui tiang listrik dan masing-masing dipasang sebuah lampu LED (Light Emitting Diode). Selanjutnya pada salah satu warung di dalam lokasi wisata dibuat instalasi lampu dan stopkontak untuk charging hand phone. Lampu juga terpasang pada sebuah rumah yang berdekatan. The Menaming Dam is located in Menaming Village, about 3 km apart from residential areas, so it is far from the reach of electricity service providers. Water from the dam is distributed through irrigation channels to residents' rice fields and fisheries containing a lot of hydraulic power. Community service activities aim to provide electrical power needs by developing a pico-hydro power plant because the location is being developed to become a tourist area. Utilization of water resources in irrigation can be done by developing a waterwheel as driving for electricity generators. The power plant with an undershot waterwheel is very suitable to be developed because it is easy to manufacture and maintain. Besides that, the structure and shape can add to the beauty and attractiveness of visitors to tourist sites. Now a hydroelectric power plant has been installed with a total power of about 70 W.

Abstract

Aerodynamic has a major influence on vehicles moving at a certain speed. Aerodynamics is influenced by the form factor and air flow that comes in contact directly on the surface of the vehicle, causing obstacles and flow separations that occur in the rear of the vehicle that affect the stability of the vehicle. Obstacles that occur significantly affect vehicle fuel consumption. Thus the purpose of this final project is to simulate coefficient drag and coefficient lift that happened to the Asykar Proto UNRI car using CFD (Computational Fluid Dynamics). Analysis is done to find out the size coefficient drag and coefficient lift and the flow form that works on the Asykar Proto UNRI car with a maximum speed of 80 Km/h. The body shape of the car is designed using software Inventor 2017 then exported to ANSYS 16.0 to do summulation. The research results obtained are magnitude coefficient drag and coefficient lift which works on Asykar Proto UNRI cars which are 1.5 and 0.032. Refers to the result obtained by the experiment changing the shape of the front and windshield the value is large of coefficient drag and coefficient lift decreased to 0.15 and 0.0030. This is because the body on the front and the windshield of the part is the body part of the car that determines the amount of drag. Whereas value coefficient lift on the car Asykar Proto UNRI itself does not affect the stability of the car (lift force) when it runs at a speed of 80Km/h.Keywords: aerodynamics, coefficient drag, coefficient lift, Iventor 2017, ANSYS 16.0.

Abstract

This study compares the performance of a bearing with surface waviness liner to a plain bearing. Both bearings are functioned with palm oil as lubricant so that the potential advantages of the journal bearings could be identified. CFD analysis is developed to predict the numerical data for full film lubrication condition. A bearing of 60 mm in diameter with its ratio of length to diameter is 0.5, a clearance 250µm, and 200µm of wave amplitude is simulated. Semi circular wavy surface produces better results in term of load capacity than the plain journal bearing for a small eccentricity. The load carrying capacity is influenced by the increasing in speed of the shaft and the eccentricity ratio.

Abstract

This study was conducted to determine a suitable and appropriate propeller for use on unmanned surface vehicles. The tests involved varying the number of blades-2, 3, and 4 of fixed pitch propellers type to assess thrust, propeller performance during straight-line motion and maneuvering, as well as the flow patterns around the propeller that have the potential to cause cavitation. The experiments were carried out in both a reservoir and a test tank. The results showed that the average thrust produced by the 2-blade, 3-blade, and 4-blade propellers was 13.32 N, 17.13 N, and 12.78 N, respectively. In the straight-line test over a 20-meter distance, the average speeds achieved were 1.49 m/s (2 blades), 1.40 m/s (3 blades), and 1.21 m/s (4 blades). For maneuvering, the average speeds recorded were 0.80 m/s, 0.61 m/s, and 0.49 m/s, respectively. Flow pattern analysis around the propellers revealed that cavitation occurred in almost all conditions and blade number variations. The fewer the blades, the more clearly cavitation bubble formation was observed. Similarly, increasing the propeller rotational speed can lead to a higher rate of bubble formation. Overall, the 3-blade propeller yielded the best performance for unmanned surface vehicle, offering an optimal balance of thrust, speed, maneuverability, and more controlled cavitation potential.
