In principle Manoeuvrability vessel is strongly influenced by the design of the hull, propulsion system and steering system. Some of these elements are directly give a significant effect on the hydrodynamic force and moment when the ship maneuver. Analysis of hydrodynamic aspects is a stage that is absolutely necessary in the design process of a ship, especially for ships operating in waters with varying depths. By the time the ship through the shallow waters can increase frictional resistance surge barriers and the vessel which resulted in a decrease in speed boats. The hull form with rise of floor and without the rise of floor by focusing on the analysis of the obstacles, the character of the ship motion and acceleration criteria in deep and shallow water conditions. In numerical calculations for shallow water conditions (shallow water) with a ratio of water depth and draft of the ships, h / d = 1.2 and deep water (deep water) with h / d = 20. Evaluation of the obstacles, the character motion and acceleration for heave, roll, pitch and yaw is done by combining numerical methods through Hullspeed and AQWA Ansys program. From this numerical calculation, it can be analyzed with the rise of the hull form floor and without a rise of floor optimum for deepwater and shallow.

One of the most commonly discussed Cardiovascular diseases is a stroke uniform caused by the stagnation of blood flow to the brain due to the narrowing of blood vessels by fat (atheroclerosis). This study examines the effect of reducing the number of lumen areas and the location of the blockage to human blood velocity, pressure, and flow rate by using CFD (Computational Fluid Dynamics). In the modeling stage, 13 kinds of luminal cross-sectional area were collaborated with 2 clogging locations and 1000 calculation was done. From the simulation, results obtained the value of pressure velocity and discharge. From the results show that the value of velocity reaches peak at 28-30% of lumen cross-sectional area and decreases at 30% cross section. The simulated debit values show that the larger the area of the lumen cross section, the higher the flowing blood flow and the opposite. While the analytic results show the value of speed is increasing and the decreasing pressure caused by the reduction of the luminal cross-sectional area, the value of the calculation of the analytic calculation shows the same values

Dalam penelitan ini akan dibahas mengenai analisis tegangan sistem perpipaan di proyek tangguh pada line 043-GN-31004/T08 yang mana fluida yang mengalir pada pipa mengalami fluktuasi pada pressure dan temperatur setiap harinya dan diperlukan analisis perhitungan tegangannya untuk memastikan jalur pipa yang telah terpasang dan tumpuan pipa yang diletakkan tepat pada tempatnya sehingga tegangan (stress) yang terjadi tidak melebihi limitasi besaran maksimal tegangan yang sudah diatur oleh code/standar ASME B31.3. Hasil analisa perhitungan tegangan akibat beban Sustain maksimum berada pada node 88 pada program CAESAR II sebesar 171.999 Kpa dan perhitungan manual sebesar 245527.7 Kpa dengan deviasi perhitungan sebesar 12.34%. Sehingga perhitungan tidak ada yang melebihi batas tegangan yang diizinkan code/standar ASME B31.3,dan akibat fluktuasi fluida dari segi pressure dan temperatur yang mengakibatkan pipa mengalami perubahan yang tidak menentu setiap harinya maka pada node 88 perlu dilakukan perencanaan ulang dengan menambah penyangga yang lebih fleksible sehingga dapat mengikuti perubahan pipa tersebut, sehingga dapat disimpulkan bahwa sistem perpipaan di proyek Tangguh Expansion Train - 3 tidak terjadi overstress dan aman untuk beroperasi.

The alloy steel that is widely used in the world of manufacturing industry is the type of tool steel because it has special characteristics and includes special steel. One type of tool steel that is widely used by the manufacturing industry is SKD steel type 61. ST 41 steel material is a low carbon steel with a carbon content of 0.08% -0.20%. ST 41 steel is commonly used as industrial machine component, but in this ST 41 steel is not as strong as steel SKD 61. So, to improve quality to ST 41 steel. Quality improvement can be done by heat treatment process. To obtain hardness requires the heating process, holding time, cooling medium, precise hardening temperature and see the material comparison between SKD 61 steel and ST 41 steel before and after the hardening process to the nature of hardness and microstructure. Result of hardness test of SKD 61 nonheattreatment steel material has hardness value equal to 197 HV, ST 41 nonheatreatment steel material has hardness value equal to 165 HV, after hardening for temperature 900⁰C has hardness value 154 HV, temperature 950⁰C has hardness value 152 HV, temperature 1000⁰C has 161 HV magnification value. Seen in the metallographic results appear to be a change in microstructure on ST 41 steel which after the hardening structure looks more dominant after the hardening structure turned into bainite-ferrit
