International Journal of Marine Engineering Innovation and Research Vol 6, No 2 (2021)
Publisher : Institut Teknologi Sepuluh Nopember

A progressive flooding-ingress of water to a compartment of a damaged ship affects the motions of a ship. In this present study, the behavior of the motion of a ferry caused by damaged conditions in waves was investigated through the experimental work. The leakage of compartments was made into several scenarios including one, two, and three damaged compartments, and the damaged ship model was simulated in heading and beam waves. The research results show the one damaged compartment on the engine room (ER) affected extreme stern trim as well as Void No.1 affected extreme bow trim. The two damaged compartments on the water ballast tank (WBT) No.2 and Steering gear room (SGR) resulted in extreme stern trim as well as WBT No.1 and Void No.1 affected extreme bow trim. The heave, pitch, and roll responses on the damaged Void No.1 are higher comparing with the damaged ER. Also, the heave, pitch, and roll responses on damaged SGR and WTB No.2 are higher than Void No.1 and WBT No.1. The peak resonances of heave RAO on bow trim affect higher magnitude than on stern trim. Pitch or roll RAO caused by the increased bow trim or stern trim in head and beam waves has a small magnitude within the response.

Indonesia is a country with abundant potential in the field of fisheries. With this abundant amount of fish, of course, many fishing methods have been developed, such as hunting or following the movement of fish and there are methods that only stay at one point, waiting for a group of fish to approach the gathering point. Fish calling devices that only stay at one point can use sound frequencies. By using the frequency of the sound, the fish will gather at the sound source produced by the fish calling tool, Fish Attractor. This study aims to determine the frequency of sound waves in fish species. The method used in this research is to make a tool that can produce sound waves with adjustable frequency, then the instrument testing will be conducted on fish ponds. Based on the design results, the fish calling device is equipped with an Arduino Uno, LCD, Potentiometer, Speaker, Power Amplifier, and Signal Module. In this Fish Attractor tool, the frequency can be set from 0 Hz â€“ 17,000 Hz. With this adjustable sound frequency, it is expected to attract the attention of fish to get closer to the source of the sound frequency of the fish calling device.

International Journal of Marine Engineering Innovation and Research Vol 5, No 4 (2020)
Publisher : Institut Teknologi Sepuluh Nopember

The purpose of this study is to establish the importance of parameters in a water absorption process for natural particulate composite for ship’s hull applications. To attain useful and reliable outcomes, the subjective evaluation of the assessor and weights of inputs are combined in a PROMETHEE and analytical hierarchy process (AHP) approach. The PROMETHEE serves the goal of ranking while the AHP is deployed to establish the objective weighing. It was found that time is the heading parameter for the natural particulate thermoset composite solutions, compared with thickness and length. By integrating PROMETHEE and AHP, it was proved that this approach offers a higher level of confidence to composite developers than initiative practices that currently dominate choices of parameters. It is particularly useful for natural particulate water absorption parametric selection since it is an innovative and scientific choice approach involving multicriteria analysis.

Nowadays, polypropylene plastics are very often found and cause various environmental problems. Though it is known that along with polypropylene itself comes from propylene monomers obtained from refining petroleum. Besides the use of waste cooking, biodiesel fuel has many drawbacks, one of which is power and fuel consumption. Mixing polypropylene plastic waste for reuse with waste cooking oil biodiesel is an option. This study uses five variations of fuel, namely HSD, B30, C20, C30, and C40, a combination of HSD, waste cooking, and polypropylene. This research is based on experiments to analyze the impact of using these five variations of fuel on the performance diesel engines based on simulation. The performance of the diesel engine would be measured to SFOC, power, and torque produced by each fuel. Based on the results of the analysis of the performance of the diesel engine performance of C20, fuel can be the most optimum alternative fuel to the substitute B30, producing 6.0 kW of power, 238gr / kWh of SFOC, and 31.7Nm of torque.

The use of sound absorbers on many ships made from glass wool. Glass wool has a negative impact on health, which can irritate the skin and disrupt the respiratory system. Therefore, it is necessary to have an alternative sound insulation material that is eco-friendly which has capabilities comparable to glass wool, and can also be used as heat insulation on ships. These alternative ingredients are materials from natural fiber. This research made sound absorbers using coconut fiber by soaking fiber into an alkali NaOH solution. Materials are selected based on density, economic value, and ease in the manufacturing process. The sound absorbers are modified using coconut fiber which is given a soaking treatment of alkaline NaOH solution and distilled water with a percentage of 15%. Soaking aims to remove lignin content and improve the mechanical properties of coconut fiber. In this research, 9 variations were made with different compositions. Tests are based on ASTM E84 to determine the flashpoint value and the safe flame spread on the ship. From the test results, it was found that coconut coir material was given a soaking treatment of alkaline NaOH solution with a percentage of 15% for 2 hours with a density of 0.3 gr/cm3 and thickness 30 mm and using a polyurethane adhesive. The time to reach the flashpoint is 20.45 seconds and the average temperature of flame spread is low when compared to other specimens including glass wool. The conclusion obtained is that the sound absorbers are safe when used on a ship.

Container port’s loading-unloading process is still using heavy equipment with less eco-friendly fuel. However, currently, several container ports are implementing an eco-friendly port (green port) concept. Renewable natural resources, such as the sun’s heat energy, are used as an alternative to supports the green port concept. Container cranes, the main heavy equipment in the loading and unloading processes, are generally supplied with electricity from PLN and diesel generators. In this research, it was tried by modeling container crane’s one-line diagram into ETAP, but by adding renewable energy resources simulation, such as solar panels. Solar panel’s characteristics, such as voltage and output frequency are different from PLN and diesel generators. Then, the difference results will be analyzed. After the simulation, results in comparison, known that solar panels can be used for container crane’s electrical system supply. In this study, the PV’s inverter output voltage is 0.38 kilo-volt. The PV supply simulation results in lower power efficiency and higher voltage drop than the PLN and diesel generator’s supply. As for each PV supply scenario, power efficiency and drop voltages are still within the IEC and IEEE standard limits. For example, in the gantry scenario, the power efficiency is 94.44%, and the drop voltage is 0.274%.

Marine business is one of the largest businesses in the world. Exports and Imports of human necessities in the majority are using ships. This is because of the ratio between the goods that can be delivered on each trip and the number of trips it can go to fulfill this. This makes the shipping or transport cost-efficient. But the continuous growth of the world population and its standard of living creates an ever-increasing dependency for the world economy on international trade. Therefore a good shipping company will always develop a better way of shipping together with more efficient and optimized voyage planning. To increase the efficiency of shipping, companies try to reduce the cost of almost everything. Therefore, one of the options for improving the efficiency of shipping is by increasing the efficiency of the ship itself. The ship efficiency is not only determined by how fast the ship and how much the ship can load, but also how much fuel does the ship consume for each operation. An investigation of the engine efficiency must be done. The investigation will be done by using an engine model in Simulink to create a similar engine model to the real engine. Then simulate the dynamic process of the engine, which will affect the consumption in general. Therefore the consumption of the engine can be analyzed. The results of this bachelor thesis is an explanation of how to develop the engine model. This includes the explanation of what is the engine efficiency and the engine parameters that affect efficiency, such as engine consumption, engine losses, etc. The model development includes the change in parameters and model structure. Then a simulation is done to compare the results with the measured data. From this process, the model can be considered satisfactory when the results are similar to the measured data.
