One of the alternative and renewable energies is green diesel. Despite the fact that both use the same raw material, vegetable oil, the processes for producing green diesel and biodiesel are somewhat different. Green diesel is generated via the hydrotreating process, which involves injecting hydrogen gas into an oil to remove oxygen. The combustion process in the engine is influenced by the nature of the fuel. Green diesel fuel has a higher yield of material than biodiesel fuel. High pressure caused by combustion in the engine combustion chamber affects the vibrations and noises of diesel engines. By varying engine speed and load, this study compares noise and vibration produced by green diesel fuel to biodiesel B30 using a simulation process. The results showed that green diesel fuel produces more noise and vibration than biodiesel B30 fuel and that this is directly proportional to the pressure and power produced in the combustion chamber by the green diesel fuel combustion process. As the pressure in the combustion chamber rises, the explosion becomes more powerful, resulting in increased diesel engine noise and vibration.

A sea-going vessel will always face the risk of rough weather along with its voyages. The focus of this paper is on the creation of a data-based model to estimate the power increase or speed loss due to the influence of weather, by using resistance estimation theories and added resistance approximation methods along with additional assisting tools. Furthermore, a theoretical simulation is done in order to benchmark and correct the model setup. The analysis of simulation results shows that at the available data range, the model proves reasonably precise within its capabilities, for academic applications. The general behavior of the model complies with common ship theory, however, does not perfectly resemble the speed-power relation of the ship’s recorded data averages. The analysis suggests that the model is most compatible with the shipload draft of 9,0 to 9,5 meters and within the speed of 19 to 22 knots. The lack of data outside the typical operating range disables the ability to verify the model correspondingly. The theoretical simulation proves valuable in assessing ship data-based models.

The most ship accidents occurred on size between 35GT and 500GT, including traditional wooden boats. The accidents were dominated by capsizing due to bad weather. Therefore the safety of traditional wooden boats needs to be improved. This paper discusses the position of bilge keels and their impact on the roll motion performance of an Indonesian traditional wooden boat. The roll damping is determined by a roll decay test with three different positions of bilge keels, namely 15 degrees, 30 degrees, and 45 degrees. The roll amplitude is determined in the frequency domain by solving the uncoupled nonlinear roll motion equation with an effective wave slope coefficient calculated using the simplified Froude-Krylov assumption of roll exciting moment. The bilge keels position with the angle of 15 degrees reduced the roll amplitude of 18% while the position with an angle of 30 degrees decreases the roll amplitude by 7% of roll amplitude without bilge keels. The bilge keels position with an angle of 45 degrees reduced the roll amplitude by 2% of those without bilge keels. The natural roll period was not significantly affected by the bilge keels position. The bilge keels position with an angle of 15 degrees is the most effective position to reduce the roll amplitude.

The application of a dual-fuel engine has massively been used as the main engine. However, in dual-fuel engine operations, problems occur in low-load operations. The combustion quality with unstable combustion conditions and relatively low thermal efficiency. In this research, a gas split injection strategy was implemented on the dual-fuel engine. The purpose of this research is to compare the performance of the engine between dual-fuel operations using gas split injection strategy and single injection. Furthermore, split injection is a fuel injection system by dividing the injection into several injection stages with a certain mass and period. This injection system was applied on a dual-fuel engine system, which was previously a modification of the conventional diesel Yanmar TF 85 MH. The variation in this study is the injection split ratio (ISR) 75-25, variations in injection time, and variations in load with specified engine speed at 2000 RPM. The results obtained in this study are the best variations found in ISR 75-25 gas split injection with injection distance at 260°bTDC & 244°bTDC. Due to the injection distance, a significant difference occurred in all parameters tested between single injection and split injection. The significance of the difference in power, torque, BMEP, SFOC, and the thermal efficiency only occurs at 100% load, which is 4.3%; 4.2%; 4.2%; 16%; 18.3%.

Various attempts to modify the ship's propeller have been made to improve performance as a propulsion component. This paper analyzes the effect of modification of the B-Series propeller by adopting a whale fin shape (Humpback Whale). Also, it analyzes the flow in the propeller before (standard) and after modification. Modifications are made to the leading edge, which is called the tubercle leading edge (TLE). It adds and subtracts sections with a wavelength of 0.2R and amplitude of 2.5% of the chord section length in the propeller leading edge. The numerical study is used using CFD on different J values (0.2, 0.4, and 0.6). It was found that the modification of TLE has a less significant effect on performance. Instead, it decreased at a low J value (0.2). Meanwhile, the largest decrease was at a high J value (0.6), namely up to 10.4% for thrust, 4.3% for torque, and 6.4% for efficiency. Whereas at J=0.4, the torque increases only 0.4%, and the torque and thrust decrease, although less significant. The flow analysis indicates that the shape of the TLE provides a decrease in pressure. However, on the positive side, this modification provides a reduction in noise on the propeller surface.

The increase in electricity demand in Selatpanjang, Meranti Island Regency, Riau continues to occur. However, the availability of diesel fuel types is increasingly scarce and the price is increasingly expensive. Therefore, another generator is needed, namely a relatively cheap coal-fired power plant and the availability of coal reserves in the Sumatran region. One of the problems in the economic operation of a generating system is economics dispatch, which is how to obtain minimum operating costs while meeting existing and reliable limits. For this reason, an economic dispatch analysis is needed for the optimal generating system by using the linear programming method. This economic dispatch analysis uses operational cost as a parameter and is done by using software assistance in the form of Matlab. Based on the results of loading with the same variation, the power generation based on economic dispatch calculations has an average load factor smaller than the average load factor based on unit commitment improvement calculations. Thus, the generation with economic dispatch has a higher specific fuel consumption (g/KWH) than the unit commitment improvement so that the fuel consumption price is issued higher.

During the twentieth century, naval architects worked to improve the performance of pusher tugs. The ropes used to secure the pusher to a barge were prone to tearing; this problem was remedied by the development of several coupling devices, including one that was highly advanced. Previous researchers have identified three major issues regarding this matter: the vessel's seaworthiness when not coupled, safety, and suboptimal structure. The purpose of this paper is to propose solutions to the aforementioned problems by introducing an efficient compound vessel design. Comparative advantages of compound vessels are analysed. Designs of a compound barge and effective coupling mechanism are introduced. Prospective weight reduction and economic advantages of coupled barges are calculated and analysed.

Environmental needs to reduce pollution caused by used lubricants from mineral oil encourage the development of biolubricant. One of the biolubricant raw materials from plants available in the environment is the castor plant (ricinus communis). The biggest composition in castor oil is ricinoleic acid which can be used in the manufacture of biolubricants. The purpose of this study was to study the physical properties of biolubricants from castor oil, to compare the properties of biolubricants and mineral lubricants after conducting a diesel engines durability test, and comparing performance between both lubricants during durability test. Experiment were carried out on the Dongfeng R180 diesel engine using Pertamina Dexlite fuel and mineral oil Pertamina Mesran B SAE 40 as a comparison. The results of biolubricant properties test (kinematic viscosity, viscosity index, pour point, flash point, and total alkali number) were obtained according to the flash point value not fulfilling the Minister of Energy and Mineral Resources Regulation regarding standard. From properties between biolubricants and mineral lubricants after a 200-hour endurance test there is properties change in both lubricants. Increase the value of viscosity, total number of base, and flash point because it contains water in the biolubricant causing oxidation. The iron content of the biolubricants after the endurance test is greater than mineral lubricants. However, the aluminum content in biolubricants is smaller when compared to biolubricants. From the performance test obtained SFOC which is produced when using mineral oil at peak torque is 3.1% lower than compared when using biolubricants. The average SFOC in the value condition when using biolubricants is 2.3% lower than using biolubricants. The average power when using mineral lubricants is 0.72% lower when compared to biolubricants and the resulting torque is 0.23% lower when compared to using biolubricants.

The Indonesian government's policy of using biodiesel as an alternative fuel in the shipping industry is still an intensive discussion. Biodiesel as a substitute for diesel fuel has an impact on engine performance, lifetime and emission. The use of biodiesel fuel will increase the wear rate on metal components in diesel engines. From a series of tests carried out in accordance with Engine Manufacturer Association (EMA) standards, wearing on several engine components would be increase when the engine run using biodiesel palm oil (B30). The results showed that there was 19.8% aluminum content, 0.75% iron content, and chromium content in diesel engine lubricating oil with B30 biodiesel fuel higher than using diesel fuel. In addition, the clerance in the pisthon ring also increases and wear is seen on the journal bearing. However, the deposits formation in the diesel engine components made from palm oil biodiesel B30 is 5.43% increase than diesel fuel. From these results, it may be concluded that using of B30 palm oil biodiesel as fuel reduce durability of diesel engine standart.

Sea level is always changing, either influenced by meteorological aspects, gravitational forces, or geological effects. Monitoring the sea level is very beneficial, especially in such a big archipelago as Indonesia. This monitoring system is designed to use accelerometer sensor to sense the sea level changes vertically to obtain the level changes over time. This device is also featured by internet connection so that the data obtained from the sensor could be process on site using Arduino microcontroller and then sent to online website for remote monitoring process. This research is using experimental method, focusing on the electronic system design. The working flow of the research is started with literature studies and problem statement, then followed by system design, continued to software design, server building, and software and hardware integration. The last step is to test the device and analyze the result. After trial using simple pulley system, it is found that this device is able to sense the vertical level changes well, with an error for the sensor itself is at most 6 cm or about 2%. But there are some connection problems occurred between the device and the internet which resulted in a delay on the process, making the online monitoring system not perform as desired.
