Abstract

Electronic fuel injection is a mechanism of fuel injection by electronic in to combustion chamber with Electronic Control Unit (ECU) for process control enter and burning air-fuel mixture. Fuel injection system is a development of natural suction system which next five years will no longer be produced. Natural suction system produces high emissions due to inhomogenous the air-fuel mixture. The natural suction system still widely used and its possible that in the next five years it will no longer be produced. The purposes of the study are manufacture and redesign injection intake manifold by sand casting with alumunium material as a replacement of natural suction fuel system with Arduino AT-Mega 2560 as a microcontroller with crankshaft posistion sensor, unit sensor (manifold absolute pressure, throttle position, intake air themperature) to produce eficient emissions. The study method of analysis data for making conclusion is quantitive experiments twoway anova with two independent variables are (1) intake manifold type and (2) fuel flow rate volume against emissions. The study results are manufacture of injection intake manifold by using the sand casting method with aluminium material is simple mehod for changes to the injection system againts emissions with value CO 14,27%, HC 212 ppm, CO2 12,133 % and O2 6,270 %, intake manifold type and fuel flow volume significant againts emissions.

Abstract

This research is to determine how much storage capacity in the File Allocation Table 16 (FAT16), File Allocation Table 32 (FAT 32) and New Technology File System (NTFS), the use of the hard drive is currently the of the maximum capacity will not be able to use when not using the appropriate partition, because it can affect the amount of storage capacity available after the hard disk in the partition. This type of research is reviewed based on its purpose of use, so the research to be conducted is applied research because the products of this research can be used by all computer users. Ultimately, the findings from this study will contribute to a comprehensive understanding of how file system selection and partitioning can influence the actual storage capacity of hard drives, thus informing best practices for maximizing available storage space.

Abstract

H-beam steel is often used as a basic material for building construction on the coast. Cases that often occur are H-beam steel that is installed quickly corrodes. This incident is caused by the coastal area belongs to an environment with a high level of corrosiveness.From the results of the pH tester test, the value of the degree of acidity is in rangeof pH=5 to pH=7.Coastal soils contain a lot of chloride Cl. In an acidic environment accompanied by a chloride Cl element, it triggers the breakdown of the passive layer on the surface which causes an anodic region to form so that the steel is in a state of releasing electrons. The problem that occurs can be overcome using a sacrificial anode cathodic protection system, with a zinc metal protection mechanism (Zn) 99, 99% which is used as a sacrificial anode has a lower potential value than the potential value of H-beam steel as a cathode protected by zinc metal (Zn) . This value of zinc metal (Zn) is more negative than the Fe steel which potential value is . The value of the potential difference is that it can be ascertained that the released Zn electrons can flow and adhere to the protected H-beam steel.

Abstract

This study aims to evaluate the effects of increasing fuel pump pressure and varying the number of holes in the injector on engine performance. The fuel system in the engine has evolved from carburettor to injection system to improve the efficiency of fuel usage. In this study, the fuel pump pressure was increased to three levels, namely 2.5 bar, 3 bar, and 3.5 bar. In addition, variations in the number of holes in the injector were also tested using 3-hole, 6-hole, and 8-hole injectors. Engine performance was evaluated based on the power and torque produced. The research method used is experimental with power and torque measurements as engine performance data. The results showed that increasing fuel pump pressure and varying the number of holes in the injector had a significant effect on engine performance. Increasing the fuel pump pressure to 3.5 bar results in an increase in engine power and torque. The best power test results were obtained at a fuel pump pressure of 3 bar with a combination of 6-hole injectors, producing a maximum power of 11.63 HP at 6000 rpm engine speed. While the best torque test results were obtained at a fuel pump pressure of 3.5 bar with a combination of 3-hole injectors, producing a maximum torque of 43.10 Nm at 3000 rpm. The variation in the number of holes in the injector shows that the use of injectors with more holes tends to increase engine power and torque.

Abstract

This research delves into the automated functionality of robotic arm manipulators, a hallmark of Industry 4.0, within the manufacturing sector. The study focuses on precise movement adhering to predetermined trajectories, addressing the vital aspects of inverse kinematics and trajectory planning in robotic arm control. Utilizing the Matlab robotic toolbox, the research conducts simulations of inverse kinematic and trajectory planning. An experimental setup involving a robotic arm controlled by an Arduino Mega 2560 microcontroller, embedded with the inverse kinematic algorithm and trajectory planning, is executed. Data acquisition involves inputting coordinates and orientation for automatic welding along a straight path. Joint angles are measured using rotary encoders and converted into Cartesian coordinates to determine the end-effector's position. Discrepancy analysis compares measured joint angles with simulation values, revealing error margins. Movement quality of the robotic arm is assessed through Capability Processes (CP) evaluation. Results indicate disparities between experimental and simulated values. At input coordinates (400mm, 0mm, 300mm), joint angle errors of 2.51º, 0.98º, and 1.48º are observed for joints 2, 3, and 5, respectively. Similarly, at input coordinates (300mm, 0mm, 300mm), joint angle errors of 1.17º, 1.5º, and 2.7º are registered for the same joints. Trajectory error analysis during straight welding reveals average errors of 2.25 mm and 10.57 mm along the x and y axes. Mean absolute errors for joints 2, 3, and 5 are 1.9º, 0.48º, and 1.91º. Keywords: Robotic Arm Manipulators, Inverse Kinematics, Trajectory Error Analysis
