Abstract

Sistem penerangan di atas kapal penumpang kapal ro-ro 32.45 meter masih menggunakan lampu fluorescent atau biasa disebut sebagai lampu neon, lampu ini dipandang kurang efektif mengingat berbagai penelitian menyebutkan bahwa lampu fluorescent memiliki dampak negatif berupa kandungan mercury yang membahayakan lingkungan dan daya yang lebih boros dibandingkan dengan menggunakan lampu LED. tujuan dari penelitian ini adalah mengkaji tingkat penghematan daya generator untuk penerangan setelah mengganti lampu fluorescent menjadi lampu LED. Metode yang digunakan dalam penelitian adalah metode lumen atau biasa disebut metode ZCM (Zonal Caviti Method). Hasil penelitian di dapatkan jumlah beban listrik penerangan pada penerangan fluorescent yang telah di akumulasikan tiap deck sebesar 24.41 kW, sedangkan penerangan dengan jenis penerangan LED di dapatkan beban listrik penerangan sebesar 12.49 kW. Sehingga dengan hasil yang tertera di atas didapatkan efisiensi daya sebesar 11.92 kW yang kemudian akan disimulasikan pada desain gambar 3D.

Abstract

This paper discusses the prediction of ship stability before sailing. This study aims to determine the stability value of the water ambulance in specific operating scenarios. The method used in this study is the B-splines mathematical equation and the optimization method using Maxurf software, which varies ship loading by 100% DWT, 50% DWT, and 25% DWT. The results of the study showed that 100% DWT had a maximum GZ value of 40 degrees and an initial GM of 1.240 meters; 50% DWT conditions had a maximum GZ value of 41.8 degrees and an initial GM of 0.711 meters; and 25% DWT conditions had a maximum GZ value of 43.2 degrees and an initial GM of 0.653 meters. The initial GM value increases with an increasing DWT value. Meanwhile, the maximum GZ value decreased as the DWT value increased. All operational scenarios are determined to meet HSC 2000 Annex 8 monohull criteria.

Abstract

Penggunaan baja untuk menggantikan kayu Bitti sebagai bahan konstruksi gading kapal kayu dinilai tidak praktis karena melalui proses pembentukan dan pemeliharaan, sehingga penggunaan bahan lain seperti FRP sangat penting. Penelitian ini bertujuan untuk mengetahui ukuran dan bentuk penampang bahan FRP yang sesuai sebagai pengganti gading kayu ditinjau dari segi kekuatan. Metode yang digunakan yaitu elemen hingga (FEM) dan dianalisis menggunakan metode eksperimen numerik pada software. Penelitian ini bersifat kualitatif dengan mengoptimalkan bahan FRP dengan bentuk penampang I beam, I beam+flange, box of hole beam, T beam, dan U beam+flange sebagai pengganti bahan kayu Bitti. Hasil penelitian menunjukkan gading kayu Bitti memiliki elastisitas (E) = 9534.02 MPa dan momen inersia penampang (I) = 2197x104 mm4 terjadi tegangan maksimum (?k) = 7.682 N/mm2 dan lendutan maksimum (?) = 0.1 mm, untuk faktor keamanan gading kayu Bitti (Sf) = 1.28, sedangkan bahan FRP pengganti gading kayu dengan nilai (E) = 69000 MPa dapat digunakan penampang I beam dengan nilai I = 316x104 mm4, I beam+flange dengan nilai I = 288x104 mm4, box of hole beam dengan nilai I = 317x104 mm4, T Beam dengan nilai I = 478 x104 mm4, serta U beam+flange dengan nilai I = 375x104 mm4, terjadi tegangan maksimum (?k) = 52.00 N/mm2 dengan lendutan maksimum (?) < 0.082 mm dan faktor keamanan (Sf) = 1.28. Bahan FRP pengganti kayu gading membutuhkan momen inersia penampang sebesar 1/7~1/5 kali lebih kecil dari momen inersia penampang kayu gading dengan elastisitas tujuh kali lebih besar dari kayu gading. Nilai ini dapat dijadikan patokan untuk ukuran kapal di atas ataupun di bawah 70 GT ketika akan menggunakan bahan FRP sebagai pengganti gading kayu.

Abstract

Balikpapan City has an area of 508.9 km2 which has 646,727 people living here. Balikpapan City is also known as a port city because it has two domestic ports namely Kampung Baru Port and Semayang Port. Currently, the port of Kampung Baru is still active in carrying out daily activities, namely the klotok boat crossing and also the dock for motor boats berths. The condition of mobility for crossing vessels in the port of Kampung Baru that uses boat klotok is inadequate due to the lack of supporting components for access to the ship so the safety of this port is questioned. besides that, klotok ships are also only able to carry a maximum of 21 passengers and 5 motorcycles and access to loading and unloading exits is very unsafe. The purpose of this study is to design a crossing ship that can be used safely for transportation for passengers and motorcycles that will pass the sea lane for crossing to the North Penajam Paser area. The ship is designed to have an easy access door or ramp door for passenger and motorcycle mobility to improve the safety of crossings at the port of Kampung Baru. The parent Design Approach method is used in this project, this method is one way of designing a ship using comparison or comparison, namely by taking a ship that is used as a reference for a comparison ship that has the same characteristics as designed ship. The main focus to be achieved in this research obtained a General Arrangement which has more cargo than the klotok ship with a capacity of 25 passengers and 10 motorcycles, and the dimension of the ramp door used in this final project is L 1.50 m and B 1.50 m. The Principal dimension of the ship obtained in this research is Loa = 12.50 m, Lpp = 11.50 m, Lwl = 11.96 m, B = 5.75 m, B1 = 1.64 m, H = 1.8 m, T = 0.85 m, Cb = 0.56, Vs = 15 Knots. The results of this study provide a good idea of the modernization of a comfortable ferry fleet for this area.

Abstract

Ferry accidents in Indonesia happen not just once or twice, but more than that. This is reinforced by statistical data on shipping transportation accidents. Shifting or overturning of the vehicle to the side of the ro-ro ferry has a big hand in causing the ship to capsize, and eventually an accident occurs. This study aims to determine the characteristics of the lateral and vertical acceleration of vehicles based on their location on the car deck under the influence of side waves. The method used is strip theory with the help of Maxurf software, which adheres to the B-spiline mathematical equation. The results of the study detected that vehicle positioning on the ro-ro ferry car deck significantly affects the value of vertical acceleration and lateral acceleration due to rolling motion. This is one of the parameters that can cause a vehicle to roll over.

Abstract

Container ship are commonly employed in a variety of countries, particularly in archipelagic countries like Indonesia. It is a construction that is very important to consider when building a transverse watertight bulkhead ship because it serves as a compartment divider when the ship has a leak and also as a transverse strength of the ship. The purpose of this research is to see if various construction modifications of a transverse watertight bulkhead can bear the working load. The finite element method was employed in this study. Five different constructions of the transverse watertight bulkhead were used in this analysis. The highest stress value in the corrugated watertight bulkhead is 252.44 MPa, with a maximum deformation of 7.6433 mm, whereas the maximum stress value in the transverse plane watertight bulkhead with "angle stiffener" is 330.71 MPa, with a maximum deformation of 12,072 mm. on transverse plane watertight bulkhead with “Tee stiffener” The maximum voltage value of 301.56 MPa and value maximum deformation of 11,025 mm, on transverse plane watertight bulkhead with “bulb stiffener” maximum stress value of 331.98 MPa and value of maximum deformation of 13,421 mm, on transverse plane watertight bulkhead with “flat stiffener” maximum stress value is 484.94 MPa and value of maximum deformation of 16.13mm. According to the safety factor calculation, corrugated watertight bulkheads, transverse plane watertight bulkheads with "Angle stiffener," transverse plane watertight bulkheads with "TEE stiffener," and transverse plane watertight bulkheads with "Bulb stiffener" are all considered safe.

Abstract

Ship-launching technology is developing rapidly in an effort to reach a point of economic efficiency, time efficiency, security, and flexibility. On the one hand, risks to the process of launching ships using airbags are still present and can occur. Exploding airbags due to the inability to withstand the load has implications for structural damage. Excessive pressure on the airbags can cause structural deformation. This study aims to determine the effect of airbag pressure on the strength of the ship's structure. This study uses finite element-based software to analyze stresses and deformations in ship construction when interacting with airbags. From this study, it was found that the number of airbags used in the two-row layout and cross-over arrangement was 14, with the status of the airbags in terms of load distribution being safe (not broken). The maximum stress value obtained from the simulation on the two-row arrangement layout is 11.62 MPa when it is right in the frame and 9.83 MPa when it is between frames. As well as in the cross-over arrangement layout, the maximum stress is 20.24 MPa when in the frame and 13.84 MPa when in between frames. This phenomenon occurs because of the stress concentration in the frame.

Abstract

Natuna is one of the regencies in the Riau Archipelago Province, the area of Natuna Regency is 224,684.59 km2 with a land area of 2,000.85 km2 and an ocean area of 222,683.74 km2. According to the Ministry of Maritime Affairs and Fisheries, Natuna occupies the first position for the purpose of exporting fishery products from the SKPT location (Integrated Marine and Fishery Centers in Small Islands and Border Areas), namely marine fisheries resources reaching more than 1 million tons per year. The extent of Natuna waters and the large potential of existing capture fisheries resources cause the Natuna waters to be included in the Fisheries Management Area (WPP 711) which is prone to illegal fishing activities. It has been proven recently that in the waters of North Natuna there are coast guard ships from foreign countries escorting fishing vessels belonging to their countries that are carrying out illegal, unreported, and unregulated fishing activities. The purpose of this research is to design a patrol ship to carry out security missions around the Natuna waters. The method used in this design is the Parent Design Approach method. This method is known in designing ships, namely by taking a comparison ship that has the same characteristics as the ship to be designed. The main dimensions of the ship obtained in this final project are Lwl = 50.2 m, B = 9.32 m, H = 4.45 m, T = 3.5 m, Vs (max) = 25 Knots, Crew = 40 Indonesian navy. Armaments used on this ship are Oto-Melara 76/62SR 76 mm, Oerlikon Millennium 35 mm, RWS Machine Gun, and SS1-V1 Kal hand rifle. 5.56 mm.
