Generally, the planning of the material arrangement of the aluminum hull plate is always carried out at an early stage to obtain a material formation that has good economic value. One of the strategies used to obtain economic value in shipbuilding is the use of various grades of plate material. The grade of aluminum material that is often used on ships is the 5xxx series. Where this series has many grades that can be used as ship hull material options. The price difference for each grade of aluminum material for ships is a very influential variable on the economic value of shipbuilding. However, before being applied to shipbuilding, it is necessary to test the feasibility of aluminum plate connections with variations in plate grade. The aim is to provide clear information regarding the technical feasibility of selecting material grades. Therefore, in this study, a simulation will be carried out to test the strength of the plate connection with variations in the grade of aluminum material using the experimental method. The plate joint test is carried out using only the Tensile test in the laboratory with reference to the ASTM rules. The grades of aluminum plate materials used are 5052 and 5083. Connection formations are between 5052-5052, 5083-5083, and 5052-5083. From the test results, the largest average yield stress value is 202.34 N/mm2 at the variation 5083-5083, the maximum average ultimate stress value is 261.70 N/mm2 at the variation 5083-5083. For the variation of the 5052-5083 plate connection, it still has a yield stress value that is greater than the basic yield stress of the material, namely 142.97 N/mm2. Where the percentage value of the achievement level of yield strength is 113.6% of the basic yield stress value of the material based on BKI rules. However, in achieving the ultimate stress value, it is still lower than the ultimate basic stress of the BKI rules standard material, which is 193.88 N/mm2. Where the percentage value of the level of ultimate strength achievement is 70.5% of the ultimate basic stress value of the BKI rules standard material.

in preliminary ship design and ship propulsion systems, it is important to have a simple method of determining the optimization of the propeller diameter and propeller efficiency, as the minimum input data to arrive at a rough estimate of performance. This problem can be solved using propeller diagrams of the open water test series or polynomial regression. This research will introduce an optimization method for the design of the B series. The propeller design process, which was carried out as a single objective function using the MatLab code numerical method, encountered problems due to cavitation, required propeller thrust and engine propeller matching. Engine propeller matching is the matching of engine power, the hull and the propeller to achieve design speed with optimal efficiency. This research focus on case study results of testing a patrol boat with a length of 60 m. By using a computer program, this 60m patrol boat is able to reach a speed of 23.5 knots using a B5-92 and an engine power of 2935 kW with an efficiency of 64.2%. Using the DESPPC program, the 60m patrol boat is able to reach a speed of 23.5 using a B5-989 and an engine power of 2927 kW with an ETA-O efficiency of 64.5%. It can be concluded that the small computer program can be used as a B-Series propeller optimization method. For future research, this method will be developed for the other series based on polynomial regression such as Gawn series and Kaplan series.

Fish resources in FMA 572 have not been managed optimally, especially small pelagic species of 82,573 tons. These waters with high wave conditions of 0.2 – 6 meters are located around the waters of West Aceh, the West Indian Ocean of Aceh, the waters of Nias–Sibolga, the waters of the Indian Ocean–West Lampung, and the Sunda Strait. The purpose of this study was to analyze the owner requirements for 180 GT purse seine vessels as a basis for planning the ship's technical specifications. The research method using a single case study with research respondents is purposive sampling. The research findings explain that the Ship dimension is around 35 meters, the Service velocity of 8 knots, the propulsion system is I line engine model, the auxiliary engine system is a dual-engine model, the Fish storage system uses Cargo hold freezer system, and Fishing aids using Fish Aggregating Devices (FADs) and light lamps, Total crew of 27 Personnel, Fish detection equipment using fish finder equipment, Fishing gear pulling with winch mechanical and power block and the ship's operating time 50 days as well. To increase productivity, it is recommended to standardize purse seine vessels with modern equipment to improve fuel efficiency, and ship crew and reduce ship production costs, so that the price of ships is affordable for fishery business actors.

Electrical energy has become a significant need to run the country's economy. Especially during the Covid-19 pandemic, teaching and learning activities were in the main realized at home. As a result, the national electricity demand has increased significantly. The solar power plant in the marine is also a good alternative in areas that are constrained by the lack of land as a Solar Power Plant development site. This research is motivated by the need for solar power plants using sustainable photovoltaic (PV) technology, aiming to accelerate the improvement of the quality and competence of lecturers and students in carrying out sustainable Renewable Energy (REY) research by applying the Merdeka Belajar-Kampus Merdeka (MBKM) model. The research method begins by conducting a Systematic Literature Review (SLR), which can support the relevance of sustainable REY research. The result of this research is a literature review of solar canopy PV, which is modified to be valuable in courses in the form of a sustainable REY Semester Learning Plan for one semester. From our current research, we hope that in future research, solar panel technology can not only be applied on land but also more broadly. For example, it can be applied in marine waters so that the use of solar panels can be used in many places.

Publisher : Institut Teknologi Sepuluh Nopember

In Indonesia, many fishing vessels are made from generation to generation in a traditional way. As a result, the ships built did not comply with the regulations and permits of the naval architects. The fishing industry is one of the most dangerous because it works on the high seas. Therefore the performance in hydrodynamics and safety should be evaluated on these traditional vessels. The main objective of this research is to evaluate the hydrodynamic performance and safety of fishing vessels. Following standard specifications or criteria, seakeeping performance is evaluated using Maxsurf Ship Design software. Assessment of existing safety equipment uses IMO (International Maritime Organization) regulations and the Torremolinos protocol. As a result, the ship can only operate at a wave height of 0,1-0,5 meters or undersea state 3. Ship safety inspections reveal that they still do not meet the required requirements and do not have the necessary equipment specified by the World Maritime Organization (IMO).

The use of fossil diesel fuels still produces carbon dioxide emissions (CO2), sulphur dioxide (SO2), hydrocarbon emissions (HC), nitrogen oxide (NOx), and high total particles and carbon monoxide (CO). Moreover, the need for transportation of motor vehicles will always increase every year. The emission of exhaust gases resulting from the combustion process can essentially be reduced by improving fuel quality, the homogeneity of the fuel mixture, and regulating proper combustion. There are several ways to reduce exhaust emissions from diesel engines by providing precise injection pressures. This is done to get the perfect combustion. In addition, improving fuel quality is a way to reduce emissions of exhaust gases. Another one is by adding methanol to the diesel. The addition of methanol can reduce the emission of exhaust gas produced. The process of mixing the solar and methanol takes the addition of surfactants to obtain good homogeneity. Testing was conducted using simulation software with engine modeling. The result can be seen in the reduction and the addition of standard pressure 200 bar, that the emulsion fuel in SFOC (specific fuel oil consumption) suffered a decrease and increased by 0.2% and 0.3% at pressure 160 bar and pressure 240 bar. The fuel solution on SFOC suffered a decrease and an increase of 0.3% and 0.25% was produced by pressure 160 bar and pressure 240 bar. The highest NOx is produced by 240 bar injection pressures with Dexlite fuel while the lowest NOx is produced by 160 bar injection pressure with emulsion fuel.

This study uses a Computational Fluid Dynamics (CFD) approach. The main object in this study is NACA 4415 with slat variations. The airfoil used as the slat is Eppler 421. Reynolds number in this study is 3Í106. This study uses an unstructured mesh with a triangular cell shape with 137824 elements. The use of slats can improve the aerodynamic performance of NACA 4415. NACA 4415 without slat stalled at AoA=16º. Stall on airfoils with a single slat and double slat occurred at AoA=20º. Slat can increase Cl in NACA 4415; however, the difference in Cl increase is not much different when using a single slat or double slat. An airfoil with a single slat, on average, can increase Cl by 20.9129%. The average increase in Cl for an airfoil with a double slat is 25.6878%. Single slat and double slat increase Cd. A single slat increased Cd with an average increase of 26.1109%, and the average increase in Cd for airfoils with double slat was 54.6152%. Single slat can produce a better Cl to Cd ratio than double slat, but the optimum AoA of double slat is 1º higher than single slat. Visualization of fluid flow at AoA=16° shows the fluid flow separation in the airfoil without a slat. The fluid flow separation can be handled well when NACA 4415 is given a single slat or double slat.

Recently, marine big data are significantly increased. If the data are effectively analyzed, it can give an advantage, and we can harness the data that is useful for a decision-maker in maritime industries. The Marine Logistics Database (MLDB) was successfully developed in the previous studies. It was developed by integrating big data into a relational database. By utilizing the extracted data from the developed database (DB), the model of ship allocation will be established. In this study, the main purpose is to develop a ship allocation model that matches the results with the existing ship allocation. In this study, the effectiveness of the allocation model was examined by checking the port constraints, ship specification, and allocation process itself. Moreover, some simulations were executed and discussed to develop new ship allocation and analyze the effective ship specification.
