Abstract

Abstrak                                                                                 Potensi Desa Tambong yang belum tersentuh untuk pengembangan usaha adalah pemanfaatan aliran sungai sebagai sumber tenaga penyedia air untuk kegiatan akuakultur. Permasalahan yang dihadapi  masyarakat Desa Tambong adalah belum tersedia teknologi yang efisien selain penggunaan pompa listrik yang membutuhkan modal tinggi. Oleh karena itu, kegiatan ini ditujukkan untuk mengenalkan dan menerapkan teknologi yang ramah lingkungan yang dapat menyuplai air ke dalam wadah akuakultur. Alat yang tepat digunakan adalah pompa air bertenaga turbin hidro vortex yang mampu memanfaatkan pusaran air sebagai sumber tenaga untuk menggerakkan pompa. Kegiatan ini dilaksanakan pada 29 November 2023 di Dusun Krajan, Desa Tambong, Kecamatan Kabat, Kabupaten Banyuwangi dengan melibatkan 20 – 25 peserta. Pompa air turbin hidro vortex yang didesain pada kegiatan pengabdian ini memilki diameter bak pusaran 0,8 m, tinggi bak pusaran 0,4 m, lebar masukkan pusaran 0,14 meter, diameter turbin 0,65 m, dan tinggi turbin 0,25 m, serta mampu memompa air sebesar 1,5 liter/menit dengan memanfaatkan debit air sungai sebesar 44,8 liter/detik. Kata kunci: desa tambong; akuakultur; pompa air; turbin hidro vortex. AbstractThe untapped potential of Tambong Village for business development lies in harnessing river flows as a sustainable energy source to supply water for aquaculture activities. The challenge faced by the residents of Tambong Village is the absence of efficient technologies, with electric pumps being the only available option, necessitating substantial capital investment. Consequently, this initiative aims to introduce and implement eco-friendly technology capable of providing water to aquaculture containers. The ideal solution is the utilization of a hydro vortex turbine-powered water pump, designed to harness water vortices as a power source for driving the pump. This project was executed on November 29, 2023 in Krajan Hamlet, Tambong Village, Kabat District, Banyuwangi Regency, involving 20–25 participants. The hydro vortex turbine water pump created for this initiative features a vortex tank with a diameter of 0.8 m, a height of 0.4 m, a vortex entry width of 0.14 meters, a turbine diameter of 0.65 m, and a turbine height of 0.25 m. It is capable of pumping water at a rate of 1.5 liters per minute, leveraging the river's water discharge of 44.8 liters per second. Keywords: tambong village; aquaculture; water pump; hydro vortex turbine.

Abstract

These Ro-Ro vessels are the backbone of inter–island transportation in Indonesia and require an efficient propulsion system to reduce fuel consumption and improve maneuvering performance. This study investigates the influence of ducted propellers on Ro-Ro vessels using Computational Fluid Dynamics (CFD) simulations. Four blades fixed pitch propeller configuration with accelerating duct are examined with different radial gaps at the propeller tip to the inner duct surface (0.1m, 0.3m and 0.5m) at rotational speed of 229 rpm and diameter of 4.202 m. the CFD model validation show average deviation of 4.06 % for KT, 7.63 % for 10*KQ and 3.11 % for efficiency compared with the experimental data. It indicated that the numerical approach is sufficiently reliable for further analysis. The open-water test results suggest that adding a duct does not necessarily improve performance. At a 0.10m gap, thrust, torque, and efficiency decrease by 39.3%, 25.7%, and 20.3%, respectively, whereas the 0.5m gap still results in noticeable performance degradation. Wake-field visualization indicates that smaller gaps produce stronger propeller–duct interaction, with more concentrated energy, sharper velocity gradients, and greater instability near the duct outlet. These findings emphasize that duct geometry and tip clearance must be carefully optimized for the vessel’s operating conditions to fully realize the energy benefits of a ducted propeller system on Ro-Ro vessels.

Abstract

The design of components for vehicles used in tourist areas must be efficient, safe, and economical. The steering knuckle is a vital component in the vehicle's suspension and steering systems, playing a crucial role in transferring loads, connecting the wheel to the steering mechanism, and supporting braking components. This research aims to design, analyze, and fabricate a steering knuckle for a mini tourist car with a total mass of 300 kg using plain carbon steel. The design and strength analysis were evaluated using the open-source Finite Element Analysis (FEA) software PrePoMax to investigate stress distribution, deformation, and the factor of safety. The FEA results showed a maximum Von Mises stress of 86.27 MPa, well below the material's yield strength, a maximum deformation of 0.126 mm, and a minimum safety factor of 2.72, confirming a robust design. The component was designed to accommodate a 30204 tapered roller bearing. The fabrication process, encompassing cutting, machining, and welding, successfully produced a functional prototype validated through direct installation and load testing on the vehicle. This study confirms that plain carbon steel is a reliable and economical material for structural components in lightweight vehicle applications and provides a pragmatic engineering framework for developing cost-effective automotive components.

Abstract

Lack of water is one of the problems in the agricultural sector. The location of the farm which is located above the water source causes difficulties in flowing the rice field area. During the dry season, farmers are forced to lift water using a water pump. Therefore, a more economical water pump is needed, one of that is a spiral pump which is driven by an undershot waterwheel. The results of the undershot waterwheel design obtained a diameter of 1 m, a width of 1.15 m, and a blade area of 0.459 m2. The frame of the wheel is made of plain concrete iron with a diameter of 8 mm, the blade of the wheel is made of 0.4 mm thick galvanized plate, the support for the pinwheel is made of angled iron with a size of 4 x 4 cm, while the shaft of the pinwheel is made of galvanized pipe with an outer diameter of 33.8 mm and 3.2 mm thick. From the test results, the wheel rotation is 15.2 rpm, torque is 9.5 Nm, wheel power is 15.11 watts, and the undershot waterwheel efficiency is 16.54%.
