Abstract The single mobility bearing as a previous design of total hip prosthesis has severe constraints that can result in dislocation during Muslim (people who follow the Islam religion) prayer movements, specifically shalat requires intense movement. There are five movements (i.e., bowing, prostration, sitting, transition from standing to and final sitting) may generate an impingement problem for patients with prosthesis. In this work, textured dual two cases femoral head inner liner)...
Research Problems: Swimming learning in Indonesia, especially schools, still faces many obstacles that must be considered. The problem often occurs is the limited availability of adequate facilities. Many educators or trainers complain about existing facilities, rural areas. Objectives: This research aims to utilize assistive devices for swimming outcomes children aged 6-8 years. Method: uses an experimental method with a One Group Pretest-Posttest Design design. population used was all 50...
Investigation of hydrodynamic interaction between the vessel and seabed when entering shallow water is considered one most critical considerations inland waterway transport. There are many investigations into behavior ships in restricted waters, such as traveling different forms canal cross-sections. The present study aims to evaluate 750 DWT Perintis Ship moving through types determine relative effects limiting width depth cross section on ship's resistance. Two canals with sections,...
Resistance or drag is one of the most important factors in ship design, particular connection with development more efficient and environmentally friendly vessels. The shape hull under water will affect fluid flow characteristics around ship, hence causing resistance to increase decrease. If increases, size main engine subsequently, fuel consumption increases accordingly this not often anticipated by designers operators. use a catamaran for passenger carriers well known its application...
Kumbung jamur merupakan rumah untuk merawat baglog dan menumbuhkan jamur, yang terbuat dari bambu atau kayu. ini harus memiliki kemampuan menjaga suhu kelembapan supaya tumbuh secara optimal. Pengendalian kondisi kumbung biasanya dilakukan manual, dengan penyemprotan air pada jamur. Hal kurang efektif bilamana seorang petani mempunyai banyak kumbung, terlebih bila jauh rumahnya. Untuk itu diperlukan suatu teknologi dapat mengendalikan memantau kumbung. Penelitian mendesain Internet of Things...
The patrol boat is one of the critical aspects for archipelago countries, such as Indonesia, to supervise and maintain sea border. Due rough conditions, could lose its stability due loss a self-righting roll moment in severe waves. One most challenging ensure sufficient during conditions. Another challenge design that has rolling extreme This paper examines an anti-capsize ship by improving with different deck houses height. condition described when experiences angle 170°. principal...
Many ship accidents are experienced by small boats. With a large number of fishing boats in Indonesia, the risk potential is high. Therefore, an operability analysis must be conducted for various loading conditions to address any safety issues due severe vessel motion. The net cargo boat will change during its operation at sea and then affect vessel's seakeeping characteristics. This study aims determine effect changes load their on traditional boat's considering ship's intact stability. In...
Fast ferries with efficient fuel use are becoming increasingly in demand as fossil fuels become more short supply and metropolises expand all over the globe coastal estuarine environments. These criteria need to be fulfilled by Hydrofoil Supported Catamaran (HYSUCAT). A catamaran wings between its demi hulls is known an HYSUCAT, it combines positive traits of both (manoeuvrability, big deck area) wing in-ground vehicle (excellent lift-to-drag ratio). In this research, a concept design...
This study aims to prove the usefulness of a bulbous bow traditional catamaran fishing vessel. Bulbous applications are widely used reduce wave resistance. The vessel resistance was calculated using CFD (Computational Fluid Dynamic) approach and combined with classical slender body theory. In this research, application being adopted on total has based Kracht method. Modeling procedure developed by linear form coefficients. ship simulated Tdyn software which basically Finite Element Method....
The sloshing phenomenon is one of the free surface flow that can endanger liquid cargo carriers such as ships. Sloshing defined resonance fluid inside a tank caused by external oscillation. When close to natural frequency it could Particle method has advantages be applied because dealing with surface. One particle methods Smoothed Hydrodynamics (SPH). In this study, compressible SPH was used result pressure oscillation, which exists effect density fluctuation nature weakly SPH. To reduce...
Drag is one of the main factors in improving fuel efficiency. Various study regards to improve drag performance a planing hull amongst them stern flap. The parameters design flap are span length and angle works by changing pressure distribution over ship's bottom creating lift force on transom part. This aims analyze behavior variations towards Fridsma form. Finite Volume Method (FVM) Reynolds-Averaged Navier - Stokes (RANS) used predict resistance during simulations. Results show that shear...
Analisis seakeeping (kemampuan olah gerak kapal) merupakan aspek penting dalam perancangan kapal. Berdasarkan analisis tersebut, dapat diketahui batas operasional dari sebuah Salah satunya adalah mengetahui kemampuan kapal pada tinggi gelombang signifikan (Hs) tertentu. Memodifikasi bentuk haluan dengan membuat dasar tersebut lebih rendah dibandingkan lambung nya (dibawah garis baseline dinamakan Anti-Slamming Bow . Pada penelitian ini, anti-slamming bow ditambahkan bulbous yang dengn...
Abstract CFD is a numerical approach used to solve fluid problems. In the simulation process, meshing stage crucial produce high accuracy. Meshing process where geometric space of an object broken down into many nodes translate physical components that occur while representing object’s shape. The research objective was analyze characteristics mesh technique in Finite Volume Method (FVM) using RANS ( Reynolds - Averaged Navier Stokes ) equation. three techniques, namely overset mesh, morphing...
