Abstract

Diesel engines are machines that are very necessary in the industrial world, both manufacturing and transportation. How important is the existence of this diesel engine that it needs to be maintained properly to maintain its performance. With the development of diesel fuel variants, it is necessary to conduct research regarding the phenomena produced by burning biodiesel, especially the B35 type which is widely consumed in the industrial world. The aim of this research is to determine the performance of diesel engines, are specific fuel oil consumption and thermal efficiency produced by diesel engines using B35. The experimental method was applied by varying the load of 0.35 kW, 0.7 kW, 1.05 kW, 1.4 kW and 1.75 kW on an engine speed of 1500 RPM. The results show that the highest specific fuel oil consumption is at a load of 0.35 kW, that is 1361 mg/kWh, while the highest thermal efficiency at a load of 1.75 kW reaches 17.25%.

Abstract

Purification or separation is important in the performance of the purifier to be able to avoid problems that occur in the boat engine. Therefore, it is necessary to carry out maintenance through fuel cleaning to have good fuel quality. The purifier itself functions to clean fuel from liquid and solid impurities (sludge) which can cause damage to the engine due to the use of unclean fuel. The methods used are namely the descriptive qualitative method. If you want to get quality fuel, it is necessary to select the appropriate gravity disc, measure the temperature of the fuel before purification, and ensure that the bowl is in a normal state and finally maintain the bowl regularly

Abstract

To support the smooth operation of maritime transportation, particularly in the transportation of liquids such as FAME oil, factors that can influence cargo loss must be properly managed. Deterioration in quality or loss of cargo volume can occur for several technical and non-technical reasons. One of the main factors causing FAME cargo loss is a leak in the ship's hull or poorly maintained tank structures, resulting in partial cargo loss during the voyage. Furthermore, inappropriate vessel characteristics, such as suboptimal carrying capacity, are also a major cause of cargo loss. Inaccurate unloading and unloading procedures, such as careless handling, also contribute to this problem. The impact of FAME cargo loss is significant, both financially and on the company's reputation. Claims received from charterers regarding losses can be detrimental to the company, and decreased customer confidence can impact shipping volumes and revenue. To minimize the risk of cargo loss, companies need to implement effective strategies, such as routinely inspecting vessels and storage tanks to ensure there are no leaks. Training crews in proper loading and unloading procedures is also crucial to avoid human error that can lead to losses. Implementing a regular visual and technical inspection system will improve operational quality and minimize cargo loss during FAME transportation. Furthermore, the use of more advanced monitoring technology, such as sensors to detect leaks or changes in tank pressure, can help detect problems early. Data-driven maintenance management systems can also be used to monitor vessel condition and optimize maintenance schedules, thereby reducing the risk of damage that could lead to cargo loss.
