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

The sprocket and chain transmission system was used to transmit the rotating force that occurs between two shafts where they can reach it. The sprocket and chain transmission system transfers a movement from the driving source to the moved object. If the maintenance of the sprocket and chain transmission system is carried out only occasionally, the sprocket and chain may cause misalignment. That can affect the machine's performance and cause a breakdown of the machine's components. This study aims to determine the effect of misalignment on the electric current usage and shaft rotation speed in the sprocket and chain transmission system. The leading equipment used in this study is a sprocket and chain alignment kit, while the auxiliary equipment used are ampere meter, tachometer, and other equipment. Measurements of electric current and shaft rotational speed were carried out with a variation of misalignments. The study results show that the increase in the misalignment causes a higher electric current. As for the effect of misalignment on shaft rotational speed, the rise in the misalignment causes the post-rotational rate to lower.

Abstract

Manufacturing of valves generally uses brass alloy materials and is carried out using a forging process. In this research, the aim is to determine the effect of variations in heating temperature in the valve manufacturing process on the hardness value, microstructure, and shape changes that occur. This research method uses this research method, using an experimental method with temperature variations tested of (300˚, 400˚, and 500 ˚Celsius) with an unchanged compressive force and brass raw material with specifications Cu = 57%. Results of observations that occurred namely Hardness Testing, the lower the heating temperature, the higher the resulting hardness value, which is 69 HRb, 66 HRb, and 59 HRb. When the shape changes, the higher the temperature, the more flash you get, and the lighter the forging force on the forging tool. In the microstructure, as a result of temperature differences, each grain structure characteristic will be different, increasing temperature and forging pressure will change the grain structure.

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.

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

ATMI Duta Engineering company is a manufacturing company engaged in the field of sheet metal with a material cutting process using laser cutting technology. Sheet metal products produced at ATMI Duta Engineering company is very diverse, one of which is the base cabinet. The base cabinet has main components, one of which is the shelf. Based on the data obtained from the interview process, there are problems, namely the shelf has never been analyzed, there are no finished products, and there is a risk of damage due to excessive loading. The solution to the shelf problem is to carry out a shelf design analysis using the finite element analysis method through Solidworks CAE software. The CAE simulation was applied to 27 variations of the shelf design by combining 3 test variables, namely the shelf model, the reinforcement model, and the thickness of the material. The material used in the simulation is SPCC material with a thickness of 1mm, 1.2mm and 1.5mm. The CAE simulation results obtained are then compared with reference to the SEFA 8M-2016 standard. The loading given in the CAE simulation is ± 108 kg (1.2 SEFA standards). The strongest variation obtained from the elimination process is variation 19 with a combination of shelf model 1 design, reinforcement model A, and with a material thickness of 1.5mm. Variation 19 meets the SEFA 8M-2016 standard because the displacement value is 1.065mm and this value is smaller than 6.35mm.

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.
