Abstract

Sandeq is an Indonesian traditional boat that is built instead of applying principal spiral design and technical calculation in its design and construction. Its construction relies on the inherited skills of the builders. This study aims to investigate the structural strength of the boat with numerical experiments by computer software that applying the finite element method (FEM). Longitudinal and transversal hull strength will be examined for four Sandeg models. The computational model of the boat hull has been designed and run with varieties of hull lengths using the software. The simulation results showed that the obtained longitudinal and transversal stresses were less than the allowable stress of the material based on the classification rules. In the transversal strength analysis, the ratio of working stress to material stress was 6,37%, 7,20%, and 5,98% on the sandeq A, B, and C respectively. As for longitudinal stress in hogging condition, the ratio was 2,77% 3,35%, 0,93%, and 0,72% on the sandeq A, B, C, and D respectively. for sagging condition, the ratio was 2,11%, 2,49%, 0,52%, and 0,69%.

Abstract

Perencanaan kelistrikan kapal harus dilakukan secara cermat dan akurat karena akan berpengaruh terhadap besar daya generator yang akan digunakan. Generator kapal dirancang untuk mampu mendistribusikan listrik untuk kebutuhan power (pompa), Penerangan (Lightning), Komunikasi dan Navigasi untuk berbagai kondisi pelayaran.  Sama halnya dengan kapal lainnya, TB Liberty  juga memerlukan distribusi tenaga dari generator untuk suplai kebutuhan listrik di atas kapal khususnya untuk penerangan kapal. Tujuan dari penelitian ini adalah untuk mengetahui besaran daya listrik yang dibutuhkan untuk distribusi penerangan diatas kapal dengan menggunakan lampu Light-Emitting Diode (LED). Metode yang digunakan adalah metode zonal cavity dengan konsep dasar membagi setiap ruangan menjadi tiga bagian yaitu height ceiling cavity (hcc), height room cavity  (hrc), dan height floor cavity (hfc) serta penentuan nilai iluminasi sesuai dengan standar yang telah di tetapkan oleh American Bureau of Shipping (ABS). Hasil penelitian menunjukkan bahwa besar beban listrik untuk distribusi penerangan pada kapal TB Liberty dengan menggunakan lampu LED yaitu deck buttom plane sebesar 0.633 Kw, pada main deck sebesar 0.6625 Kw dan pada geladak navigasi didapatkan sebesar 0.238 Kw. Penelitian ini mampu menjadi rujukan dalam penentuan kelistrikan di atas kapal khususnya untuk instalasi penerangan kapal.

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

Tourism ship with the Phinisi ship concept for the Selayar Islands tourist area are designed to increase the number of tourist attractions in the area. With beach tourism destinations and coral reefs, the Selayar region is very possible to become an alternative tourist destination in Indonesia besides Bunaken, Raja Ampat, Labuan Bajo, and the island of Bali. This ship is designed with wood materials and carries the theme of the traditional Phinisi ship which is the hallmark of ships made by the Bugis-Makassar tribe since 3000 years ago and has been recognized by UNESCO as one of the world's cultural heritage (Art of Boatbuilding in South Sulawesi). This study aims to obtain a tourist ship design that can be an attraction for tourists to vacation in the Selayar Islands. The method used in this study is the parent ship design approach method, this method is very commonly used in the ship design process, namely by using a comparison ship as a reference in the design of a new ship. The main ship dimensions obtained from this research are Loa = 26 m, B = 6.1 m, H = 2.48 m, T = 1.6 m, Vs (max) = 10 Knots, and Crew = 6 persons. The room on the ship is made like a classy hotel room and other services can pamper tourists.

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

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

In the welding process, it is not uncommon for a defect or discontinuity to occur in the welding results. Common defects on the surface are undercut, concavity, incomplete penetration, spatter, burn-through, and mismatch. While defects in internal welds that are often found during testing are porosity, worm holes, slag inclusions, incomplete fusion, and cracks, To obtain pipeline results that comply with the specifications set by the welding engineer and ASME or ASTM standards, it is necessary to test surface cracks and inside cracks using the non-destructive test (NDT) method, namely the dye penetrant test and radiography test, to determine the results of welding at pipe joints. In addition, it is also necessary to know the time and cost required for each method in the testing process. The results of the radiography test and penetrant test on carbon steel pipe welding joints showed porosity welding defects 1 mm long. Weld defects in duplex stainless steel pipes were not found. Then the results of the total testing time using the radiography test take 18% longer than testing using the penetrant test. Furthermore, the total costs that need to be incurred during the test are found to be 2~3 times more expensive than the cost of the penetrant test.

Abstract

To address the challenges faced by the government in the realm of petroleum imports, a promising strategy was adopted in the utilization of biodegradable and renewable sources of biodiesel, such as coconut oil. This research employed two distinct methodologies: Transesterification for biodiesel synthesis and a comprehensive assessment of fuel properties. Subsequently, an experimental phase assessed biodiesel within an engine environment to analysis performance metrics. Results showed that B30 (30% coconut oil, 70% diesel oil) has density of 0.850 g/cm³, B50 (50% coconut oil) at 0.861 g/cm³, and B100 (Pure coconut oil) at 0.893 g/cm³. The values differed from regional standards. As per ASTM D6751, B30 has a viscosity of 2.31 cSt, B50 3.22 cSt, and B100 is 7.02 cSt. Engine performance revealed B50 with the highest torque at 11.787 Nm, while B0 (pure hydrocarbon diesel) has a thermal efficiency of 38%. B0’s lowest SFC (Specific Fuel Consumption) is 261.12 g/kWh at 2000 watts load and 1000 rpm. Biodiesel coconut oil provided comparable power and torque (0.3% difference from B0) but consumed more fuel (21.6 % higher usage than B0). Keywords:  Biodiesel, Coconut oil, Engine performance, Fuel properties, Transesterification.
