The need for hot water on a ship is one of the facilities that must be obtained by the crew while carrying out their duties on the KM. Meratus Karimata is one of the ships that provide hot water as a facility for crew members. The heating system on this ship still uses the EHHW (Electric Heating Hot Water) heating system which will then be changed to the HPWH (Heat Pump Water Heater) system. This hot water need is based on the MLC (Marine Labor Convention) regarding the provision of recreational facilities on deck accommodation. The provision of hot water needs to be calculated and designed. The first thing to do is to calculate all distribution support components. Then the data for the needs of pumps with a power of 0.504 Kw, valves, shower taps, sink taps, pipe connections, and SCH 40 pipes with a diameter of Â¾ "and 1" are obtained. After that, the design is carried out using software assistance. After the design is carried out, the calculation of component costs is carried out with details of the valve price of IDR 10,129,000, pipe IDR 5,186,000, pipe connection IDR 1,751,000, supply pump IDR 1,150,000, HPWH 95,300,000. The price of EHHW and HPWH is a difference of IDR 21,300,000, which is more expensive for HPWH. However, in the calculation of fuel consumption, HPWH is more efficient with HPWH fuel consumption data of 0.11 liters/hour at a cost of Rp.1,249 / hour, while fuel consumption for EHHW is 0.77 liters/hour at a cost of Rp.10,116/ hour.

The diesel engine as the main engine on the ship can function properly if it is supported by good supporting systems such as a lubricating oil system. The lubricant system is one of the most important systems in ship operation, failure in the lubrication system causes the system to not operate properly and can suffer losses from the ship. This study aims to determine the failure of each component of the lubricating system in the main engine and its proper maintenance. This study was conducted using the Failure Mode and Effect Analysis (FMEA) method to optimize the way to overcome the failure and maintenance of the ship's main engines to identify strategies and maintenance priorities. By using FMEA, we can determine the failure and the effect caused by each component and to perform maintenance must classify components based on low to high risk levels. The components of lubricating oil tank and sump tank have a low risk, lubricating oil cooler has a moderate risk and lubricating oil pump, lubricating oil filter, purifier, transfer pump and lubricating purifier heater have a high risk. The results of the failure of lubricant system components are very useful in identifying maintenance strategies based on the level of risk of these components by choosing between preventive maintenance and corrective maintenance.

Failure in a component in the lubricant system will have an impact on the operation so a review is needed to overcome the failure of each component and the maintenance of components based on the level of risk. The creation of a risk-based treatment analysis with the FMEA method has several steps that describe the identification and evaluation of the system, process and treatment to determine the treatment strategy resulting from the method. Failure Mode and Effect Analysis (FMEA) is a method of evaluating risks in the system. FMEA can evaluate and analyze components in a system so as to minimize the risk or effect of a failure rate as a method of supporting performance assessment on a system. The use of FMEA methods other than in industrial machinery is widely used also to analyze preventive maintenance planning on ship machines. As a result, the FMEA method can identify the priority of the highest ration stainer component rpn value (Risk Priority Number) compared to other components. This study to determine the failure of each component of the lubricant system in the diesel engine and choose the right type of maintenance for the components. The benefits of knowing the failure and koponent maintenance of the lubricant system will provide benefits to the ship in terms of maintenance..

The propeller is a key component in ship propulsion as a means of producing thrust to move the ship. The damage that occurs to the propeller on the propeller leaf is fouling, erosion occurs due to cavitation, cracks and bends occur due to collision. This research was conducted to analyze the effect of welding position and filler diameter on the results of welding repair of propeller leaf with GMAW. The tests carried out are tensile tests, hardness tests, impact tests and macrographic observations. Tensile test results on GMAW welding for maximum tensile strength at the 2G welding position have a high ultimate tensile strength value. In the 1G and 2G welding positions the macrographic observations were good because there were no welding defects found compared to the 3G welding position. The highest hardness results in 1G welding compared to 2G and 3G welding positions. The result of the highest impact test is the 1G welding position compared to the 2G and 3G welding positions. Based on the results of testing the difference in filler diameter, defects were found in the test samples at the position of 2G filler 1.2 mm, 3G filler 1.0 mm, and 3G filler 1.2 mm, while the position of 1G filler 1.0 mm, 1G filler 1.2 mm, and 2G 1.0 mm filler found no defects. For the tensile test, the hardness and impact on the 1.0 mm filler diameter have a high average value compared to the 1.2 mm filler diameter.

The use of modern machinery and installations and hazardous materials is increasing. In addition, a work environment that does not meet the requirements for occupational safety and health, hazardous work processes and nature, as well as an increase in the intensity of the operational work of the workforce, affects the increase in the number and seriousness of work accidents. The type of research used is descriptive quantitative research so that the data entered are in the form of words, sentences and pictures, which are then scored to determine the level of danger before carrying out the work. In conducting a job safety analysis, what is done is to determine the work to be analyzed, divide the work into several work steps or standard operating procedures, identify potential hazards, risk assessment, evaluate risk and determine the level of risk and prevention. The assessment of the risk value analysis on replating work has a value of up to 8, indicating the need for control measures in the process. Then the coating work on the fuel area and main deck also have a risk value of 8, so it is also necessary to take control measures on the coating process in that area.

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

Proteksi katodik adalah salah satu metoda pengendalian laju korosi secara termodinamika dengan cara memperlakukan struktur logam sebagai katoda. Proteksi katodik sangat penting untuk mengurangi laju korosi pada luas permukaan bawah air pelat lambung. Proteksi ini ditempelkan pada bagian kapal yang rentan terhadap korosi air laut, Lebih tepatnya terletak dibawah garis air. Sebagian besar kerusakan pelat konstruksi baja kapal adalah disebabkan oleh adanya proses korosi. Akibat korosi ini menimbulkan kerugian material yang cukup besar, sehingga diperlukan prokteksi untuk mencegah timbulnya korosi tersebut dengan cara menggunakan katodik. Metoda pengendalian korosi pada dasarnya dapat dikelompokkan menjadi dua kelompok, yaitu metode kinetika dan metoda termodinamika. Dalam metoda kinetika pengendalian korosi dilakukan dengan memberi hambatan pada interaksi dengan lingkungannya sehingga laju korosinya dapat dikurangi, tetapi kecenderungan untuk terjadinya korosi itu sendiri tidak diselesaikan, sehingga apabila hambatan ditiadakan korosi akan segera berlangsung lagi. Penerapan proteksi katodik sering dikombinasikan dengan coating. Tujuannya adalah untuk melindungi baja pada saat coating mengalami kerusakan.
