The existence and the use of live fish hold system, can help fishermen to reduce the operating costs in fishpreservation 11.8%. The live fish hold system, which fish hold were given circulation hole so the water insideand outside the hatch is connected, there should be researched about the changes and differences in pressurethat happened when the ship moves.Initial condition where the ship is not moving, surface of water in the fish hold will be the same height with adraught of ship. When the ship began to move out, the pressure of fish hold will decrease along with increasingthe speed of the ship. This will caused a decrease of water surface elevation in fish hold.According the calculation and analysis we found on the speed of 12 knots the water surface elevation in hold ispositive with a value 0,3947 m on to 0,20 m diameter of hole circulation (before variation), 0,4515 m on to 0,15m diameter of hole circulation, 0,4656 m onto 0,25 m diameter of hole circulation, 0,4718 m on to 0,20 mdiameter of two pieces of hole cilculation and -0,9410 m for manual calculation with all variations.The optimum hole circulation was chossen at two pieces of diameter of 0,20 m because on the speed 12 knots,the water elevation is 0,4718 m. This value is the higest among the other variations of the cilculation hole

Model catamarans increasingly popular as a means of transportation of goods and people that needdevelopment to find out more in the interaction prisoners on the ship hull in order to achieve stability and betterresistance. KM Jasatirta is one of ship model catamaran (double hull) which is designed to support tourism inJatiluhur Reservoir. This study aims to find out more details interaction of the total prisoners in the ship's hullKM Jasatirta with Computational Fluid Dynamics approach.Research carried out several stages of manufacture of the Computational Fluid Dynamic model, simulationinput data, running simulations to converge, then analyzes the results of calculations by the methodSlenderBody, Delft Series, 98, and CFD. Analysis of the calculation includes the analysis of resistance, FroudeNumber economic , and comparative analysis of numerical calculation by the method of Computational FluidDynamics.The results of the analysis and calculation of reseach showed that the total ship resistance (Rt) at 2 knots boatspeed by using the CFD method at 0.37 kN, Delft method Series'98 of 0.14 kN, while the calculation method forSlender Body 0.04 kN and a analityc calculation by the method of Millward's of 0215 kN. And based on theresults of analysis of Froude number of the most economical in terms of aspects of the ship's speed is the methodof Computational Fluid Dynamics with a value of 0094 sedangan Fn projection calculation with a quadraticfunction then the value of accurate Fn Series'98 Delft method so it can be used as a reference calculation.

Planning of ship construction is make its having good effectivity value and efficiency. Composite as materialalternative to changes of steel feedstock and wood has many applied named FRP (fiberglass reinforcedplastics) single skin. The weakness of this FRP was heavy construction and requires many production time.Therefore, will be checked comparison between single skin with sandwich constructions for shell.In this research, the way for making composite is hand lay up method with three various thickness of skinthere are : t, t/2, and t/4. To know strength comparison from the various skin of sandwich with single skin,must be test, consist of tensile test.. The result is analyzed then compared by BKI (Biro Klasifikasi Indonesia)rules for the fiberglass ship.Based on the result, indicates that optimization skin thickness of sandwich construction applies Corematwhich tensile strength it is equivalent with Single Skin at 2/3t and usage of Sandwich construction causes23,12 % lighter. In economic analyze, advantage from low weight is compensation of addition 23,12 % DWT.Material cost for Sandwich about 11,35% bigger than Single Skin construction.

The Application Of Catamaran Hullform For The Fishing Vessel accorded to the leakage of the monohullform. The existence and the using of the lively fish hold could help the fisherman to decrease theoperational cost for about 11,8% to keep the fishes. Therefore the application of sail objected to reduce thebiggest cost operation component that is the fuel consumption. Catamaranhullform design for lively fish holdtook one hullform which has the best performance. The performance aspects in this case are the hydrostatic,ship resistance, stability and seakeeping.The research about catamaran fishing vessel design for lively fishes using sail and machine as the ship moveris expected to give the information about the hullform that has a better performance than the commonlyhullform and it could be an alternative to improve the fishing vessel hullform into the modern one.Accorded to the calculation result and analysis are gained the result that showed at the velocity of 12 knotsfrom some length dimension variations of fish hold for the catamaran fishing vessel with lively fish hold,variation of length of 2,0 meters could reduced the biggest shipâ€™s resistance for about 3,99% between theother modification hullform and the shipâ€™s resistance of standard hullform. Otherwise, by the stability aspectof any variation condition, fish hold length dimension variation at 2,0 meters had a better stability thananother fish hold length dimension and catamaran fishing vessel which used the commonly fish hold. Theinstallation of sail at the fish hold length dimension at 2,0 meters could reduce the power operation for about48,42% better than fishing vessel that used the commonly fish hold.

Commonly, the Computational Fluid Dynamic (CFD) analysis using the finite volume method, solid modeling is usually used in the early stage in order to prepare a mesh process before the computational process is executed. In this paper the CFD analysis must be executed to obtain a resistance coefficient value, and the verification should be done to ensure a result is close to experimental data. In the CFD analysis, some parameters have been taken into account, including the variation of domain dimensions, variation of mesh sizes, and variation of boundary conditions, in which the comparison between the numerical analysis and experimental data showed good agreement in general. The result of the case no.1 has a smaller difference of the resistance coefficients to the experimental data than other cases, in which the total resistance coefficient (Ct) has a difference about 1.95% of experimental data, the friction resistance (Cf) has a difference about 0.83% of experimental data, and there is a difference about 6.30% of experimental data for the residual resistance (Cr).

Pengujian eksperimen menggunakan towing tank adalah salah satu cara yang digunakan untuk memprediksi hambatan kapal. Metode alternatif lain yang dapat digunakan adalah metode Computational Fluid Dynamics (CFD). Metode ini menjadi trend di industri maritime karena biaya pengujian eksperimen pada towing tank semakin mahal dan diikuti dengan perkembangan ilmu dan teknologi tentang mekanika fluida menggunakan metode Computational Fluid Dynamics (CFD) yang sangat pesat. Penelitian ini bertujuan untuk untuk memverifikasi performa kapal cepat menggunakan metode komputasi. Metode CFD yang digunakan untuk menyelesaikan permasalahan mekanika fluida ini adalah dengan menggunakan persamaan Reynolds-Averaged Navier-Stokes untuk menggambarkan model turbulensi dengan k-Îµ, dengan menggunakan aliran multiphase Euler yang diasumsikan air dan udara. Dynamic Fluid Body Interaction (DBFI) adalah modul yang mensimulasikan gerakan benda sebagai respon terhadap gaya yang diterapkan oleh kontinum fisika. DBFI heave dan pitch pada penelitian ini diasumsikan bergerak bebas untuk dapat menghitung gerakan kapal. Hasi penelitian ini menunjukkan bahwa CFD dapat membantu dalam mempredisksi hambatan, trim dan kenaikan titik gravitasi.
