Abstract

One type of aircraft commonly used for flight training, patrol, and transportation in remote areas is the Cessna. It should be understood that each tool and component in the aircraft has its own level of importance and can experience failures in carrying out its functions. These failures often become a problem for users due to a limited understanding of the aircraft engine field. Issues arising from the aircraft's landing gear sometimes involve minor problems that do Does not require a high level of expertise. To solve this, it may be possible for someone with knowledge of landing gear to address the issue. By using the Case-Based Reasoning (CBR) method for fault identification, a technician's expertise in aircraft landing gear can be applied and integrated. The search for solutions or fault identification Can be obtained promptly In the testing results of the Fault System for Cessna C208B Aircraft Landing Gear using the CBR method, the system's calculations were consistent with the manual. However, the application still has some shortcomings in the system, such as the preprocessing stage, which has not been able to search for the root words in a question sentence.

Abstract

In the world of transportation, there are many things that must be considered, ranging from safety to efficiency. Propulsion system planning is very important, this is because the system is a thrust generator that will determine the performance of the ship. The thrust generated must be able to overcome the resistance or friction of the ship with water. In recent times, many studies have been conducted to improve the performance and efficiency of the waterjet thruster. In this research, the performance of the waterjet thruster will be tested with variations in the number of inlet blades and the number of turbo outlet blades. The levels used are 8 blades and 15 blades. The manufacturing process on waterjet thruster components such as inlet, impeller, and turbo outlet uses Fused Deposition Modeling (FDM) technology to obtain high dimensional accuracy. From the research conducted, it can be concluded that the number of blades at the turbo inlet and outlet has a major effect on the thrust generated. The turbo outlet has a greater role than the inlet in influencing the thrust force. From the research conducted by Nori and this study, it can be concluded that the turbo outlet with 8 blades produces the highest thrust force compared to 6 blades and 15 blades.

Abstract

Fluid is a substance that is capable of flowing. The types of fluids that are often used in everyday life are liquid fluids and gas fluids. To drain the fluid you need a laundry device called a pump. The working principle of the pump is to provide pressure or energy to the fluid. This type of research is experimental research, namely, researchers carry out experiments to obtain data in the form of numbers or quantitative data. Researchers varied the valve openings from 0o, 25o, 45o, and 65o and used a pump rotation of 1600 RPM. This research plan is to determine the effect of valve opening on pump capacity and efficiency. The research results show that the pump capacity and efficiency results at valve openings from 0o to 65o have increased significantly. The greatest capacity and efficiency occur at 65o valve openings with a value of 6 L/M and 43.2%.

Abstract

One of the alternative energy fuels in the transportation sector is biodiesel. Biodiesel made from a mixture of vegetable materials has great potential as an environmentally friendly fuel for diesel engines. This experimental research aims to analyze the effect of using Jatropha curcas (Jatropha curcas Linn) oil on diesel engines. The experiment was carried out using a mixture of Dexlite and pure castor oil (JCO) with varying compositions of JCO 0%, JCO 20%, and JCO 30%. Torque test results against load show an insignificant comparison between Dexlite without mixture and Dexlite with 20% and 30% JCO mixture, especially when loading high using Prony Brake. Although the effective engine power of the three fuel variations does not show significant differences at the same engine speed and load, the use of a mixture of Dexlite and 20% castor oil at an engine speed of 1700 rpm is more effective in improving diesel engine performance and saving fuel. Additionally, fuel consumption decreases as load increases, indicating high efficiency potential. In the context of exhaust gases, the mixture also has the potential to reduce the opacity of diesel engine exhaust gases.

Abstract

Aluminum Alloy 6061 is widely used in various engineering applications, including automotive vehicle wheels. The selection of aluminum alloy wheels involves aspects such as corrosion resistance. To enhance corrosion resistance, there are several methods, one of which is anodizing. Anodizing is a process that involves an electrolytic coating process that transforms the surface of aluminum into aluminum oxide (Al2O3), which the main process of aluminum anodizing requires a solution of sulfuric acid, chromic acid, or a mixture of sulfuric acid and oxalic acid. The sulfuric acid used must be concentrated acid, and acid is an oxidizing substance. The thickness of the oxide is approximately twice the thickness of the lost aluminum. The purpose of this research is to determine the characteristic such as surface roughness values, corrosion rates, and changes in morphology in Aluminum 6061 after undergoing anodizing. In this study, various current strengths were used, namely 0.75 Amperes, 1.5 Amperes, 2.25 Amperes, and 3 Amperes. The highest surface roughness value was obtained at 0.447 μm in the third specimen of the 0.75 Ampere variation, while the lowest was 0.075 μm in the first specimen of the 3 Ampere variation. The highest corrosion rate was observed in the 0.75 Ampere variation, with a rate of 17.724004 mpy, and the lowest was 0.0731653 mpy in the 3 Ampere variation. SEM results show that, in general, Aluminum 6061 tends to have a bright gray color, which is a surface that has been coated by cathode.

Abstract

One of the processes commonly used in making plastic goods is the injection molding process. Every process in injection molding has a very important role. A less-than-perfect process will result in defects or failure in the product. To reduce product defects, one of the processes that must be researched is the barrel purging process. The purging volume on the mini injection machine using the V-line method is inconsistent, as evidenced by the fact that if the purging waste, or what is usually called an avalanche is weighed, it will produce a non-uniform mass. This research uses a mini injection machine with the V-line method which has 2 main steps to carry out the plastic injection process; dosing and injecting. Unlike injection engines in general, this engine does not have a check-ring to withstand back pressure. This machine uses a shut-off system as a replacement for the check-ring role. This machine has never been subjected to a purging volume consistency testing process. The consistency of the purging volume greatly influences the product uniformity results. The research method used in this final assignment is direct. Data collection and test specimen collection will be taken directly on the mini injection machine using the V-line method. The steps taken in this research are planning, taking data, taking test specimens, processing test specimen data, and comparing test specimen data to obtain analysis results. The research results show that the mini V-line injection machine cannot support mass production, because increasing the screw rotation speed will affect the consistency of the volume of plastic that will be produced in the barrel, causing production to not run quickly and precisely.
