<![CDATA[Cathodic protection is a thermodynamic corrosion rate control method by treating metal structures as cathodes. Cathodic protection is very important to reduce the corrosion rate of the underwater surface area of the hull plate. This protection is affixed to parts of the ship that are susceptible to seawater corrosion, more precisely located below the water line. Most of the damage to the ship's steel construction plate is caused by the corrosion process. As a result of this corrosion causes substantial material losses, so protection is needed to prevent corrosion by using cathodic methods. Basically, corrosion control methods can be grouped into two groups, namely kinetic methods and thermodynamic methods. In the kinetic method of controlling corrosion, it is done by providing barriers to the interaction with the environment so that the corrosion rate can be reduced, but the tendency for corrosion to occur itself is not resolved, so that if the obstacles are removed corrosion will take place again soon. The application of cathodic protection is often combined with coatings. Its purpose is to protect the steel when the coating is damaged]]>

<![CDATA[Motion sickness on ships is also known as seasickness. It is a symptom of illness caused by the movement of the vessel, which results in uncomfortable physical symptoms characterized by difficulty breathing, dizziness, nausea, paleness, and vomiting. The main cause of seasickness is the absence of similarity of excitability or conformity between the stimulus, eye, and ear labyrinth the human brain receives. The direction of the waves is very influential on the stability of the ship being boarded or not. The research method uses ship motion software simulation. The study results concluded that the vessel's condition was stable, indicated by the waves coming from the 0° or the ship's state sailing in the direction of the incoming waves. Thus, it is predicted that no passengers will experience motion sickness. Meanwhile, the unstable condition of the ship is indicated by the ship with a wave direction of 180° or the state of the vessel sailing in the opposite direction to the direction of the wave. So it is predicted that passengers will experience seasickness after 2 hours of travel.]]>

<![CDATA[The main propulsion engine (MPU), or the main motor on board, is a machine that functions to move the ship forward and backwards. The MPU has two combustion air intake systems in the cylinders, namely a suction intake system that relies on the vacuum of the combustion chamber due to piston movement or a press intake system, namely by equipping the engine with a Turbocharger. The primary purpose of a turbocharger is to increase the combustion air pressure by compressing the air so that the mass of air entering the combustion chamber becomes higher than atmospheric air. If the mass of the combustion air flow decreases due to various conditions, it will affect the incomplete combustion process, which can be visually indicated by darker smoke. Incomplete combustion will affect the power and performance of the diesel engine.]]>

<![CDATA[In recent years, trade traffic through Tanjung Priok Port has always increased. An increase in the economy always has a negative impact on the environment. Because every ship that docks has the potential to dump waste in the port area. Most of the causes of marine pollution in Indonesia are caused by ship waste, of course this is related to the lack of awareness of ship operators about the cleanliness of the environment around the port. Related to this, this research was conducted to plan an environmentally friendly Oil Spill Recovery Boat, by using electric power for navigation and communication needs. Oil spill control vessel design. This Oil Spill Recovery Boat has a catamaran hull designed using the Maxsurf application. The method used to determine the main size of the Oil Spill Recovery Boat is linear regression, namely by using comparison vessels that have been compiled and then adjusted to the number of oil spills in the research area. By using Maxsurf software, the main dimensions obtained are L = 10.0 m, B = 4.42 m, H = 1.34 m and T = 0.61 m.. This ship has a crew of 3 people.]]>

<![CDATA[Coastal damage caused by sea wave attack has increased significantly recently. This will have an impact on the loss of residence and economic resources of coastal communities. In some incidents it has even claimed lives. Therefore, it is necessary to build a sea wall that can withstand the attack of sea waves both for short wave types and for long sea wave types which are usually provoked by storm winds. In this study a seawall type with double chambers was tested. From the test results it can be seen that this type of seawall is effective in being able to withstand attacks by sea waves both short and long seas because of the existence of double spaces that can expand the range of wave frequencies so that wave height can be reduced constructionally. In this study it has also been confirmed that the wave amplification value is around 2.5 times the incident wave height, which means that the wave energy in the seawall chamber can be utilized. -spasi-Times New Roman 11 Italic- Keyword: Beaches, Waves, Seawalls and Wave Amplification]]>

<![CDATA[The territorial waters of West Aceh, Aceh Province is an area with a long topography and wide sea. The water area is included in the Republic of Indonesia State Fisheries Management Area (WPPNRI) 572. The hammerhead shark Sphyrna lewini is not significantly different from the hammerhead shark Sphyrna mokarran, both of which are characterized by their heads widening laterally and being less than a third of their body shape. Sphyrna lewini has a body size ranging from 50 cm to 420 cm, which generally lives in the tropics and is easily found in island waters with a continental shelf reaching a depth of 275 m. Its important role can be seen from an ecological perspective in the development of conservation and sustainable marine and fishery resources. This should be managed responsibly for the sake of creating a prosperous and independent society. West Aceh district is a coastal area that is rich in fishery products. This is inseparable from its location directly facing the Indian Ocean which is rich in fish. However, the sustainability of the hammerhead shark is not yet known in detail. Therefore, a study on the sustainability of hammerhead sharks at PPI Meulaboh needs to be carried out. The method used in this study was a field experiment (experimental fishing) from fishermen’s catches. Furthermore, the data obtained were tabulated and analyzed. Overall, the size of the hammerhead shark caught by fishermen was in the interval of 62.5-93.5 cm. By sex, there were 19 male sharks and 20 female sharks. The maximum length (L∞) was 96 cm. Furthermore, the value of K was 0.290 per year. The Von Bertanlffy growth equation model was Lt = 91.6(1-e-0.29(t+0.03)). The value of total mortality (Z) was 0.84 and natural mortality (M) was 0.94 with a temperature of 29 0C, where the incidence of natural deaths was greater than fishing deaths. Fishing mortality (F) was 0.10, with an exploitation ratio (E) was of 0.12.]]>

<![CDATA[OT ship. Skylie is a type of tanker produced by PT. Samudra Marine Indonesia, in its construction, applies a keel cooler as a cooling device for the main engine propulsion of ships. This keel cooleris one of the new types of heat exchangers which is applied in the field of shipping. A cooling system using a keel cooler is a closed-circuit cooling system that is installed externally on the hull below the waterline. This study aims to determine the overall heat transfer value and the effect of changes in ship power/torque on the effectiveness of the keel cooler-type heat exchanger. The analysis uses two methods, namely CFD analysis and simulation using the Ansys CFX R20 application. Based on the results of calculations on several ship power/torque conditions, the largest heat transfer value is obtainednamely 5.599 x 10 5 W at 100% power condition and the lowest value is 5.055 x 105 W at 10% power condition. Meanwhile, the highest effectiveness value is 79.985% and the smallest value is 79.839%. So it can it was concluded that the use of the keel cooler on the OT ship. Skylie has met the standard value of effectiveness for a heat exchanger that is equal to 50%.]]>

<![CDATA[Increasing the cooling capacity of generator engines or condenser engines by utilizing sea water at PLTU Barru requires dredging the intake channel with a dredging length of ±80 m and a depth of -4m LWS. The problem is that dredging the intake canal has the potential to cause silting back in the area that has been dredged due to coastal hydrodynamic processes which can cause blockage of the intake canal and disrupt the process of the pumping system and the generating system as a whole. A study is needed to assess the potential for sedimentation around the dredging area. This research uses primary data and secondary data. The primary data consists of bathymetry data, currents, tides and bottom sediments and water samples. While the secondary data includes comparative wave and tidal data as well as the design of the dredging plan. Wave data is sourced from the European Center for Medium-Range Weather Forecasts (ECMWF) while comparative tide data is obtained from the Geospatial Information Agency (BIG). The data obtained is then analyzed to obtain the parameters of currents, tides, sediment and breaking waves as well as sediment transport along the coast. Calculation of sediment flows and transport was also carried out by numerical modelling using a surface-water modelling system (SMS). Furthermore, by using the results of analytical sediment transport analysis and numerical modelling, the thickness of the trapped sediment is calculated in the intake canal after dredging. The results of numerical modelling analysis show that the potential for sedimentation at the study site originates from currents due to tides and currents due to breaking waves. The predicted potential for sedimentation due to tidal currents and broken wave currents for 1 year is 43.64 m3 and 1,589.93 m3 respectively with a sediment thickness of 1.2 meters from the bottom of the excavation so that intake channel maintenance is required at least once a year.]]>
