Abstract

This critical shaft rotation test tool is used to calculate the maximum deflection of a steel shaft. Currently, the critical shaft rotation test tool still uses human power to operate it, namely by rotating the handle to read the rotation value. So the test results carried out are not effective and accurate. This tool uses an electric motor with ¼ HP power and 2800 Rpm rotation as the driving force. So that the results are more accurate, this tool is designed to use an electronic system (sensor) equipped with a digital counter. Making this critical rotation test tool for the shaft goes through several processes, namely, making a table or position of the critical rotation test tool for the shaft using a digital counter, selecting the disk (load), selecting the bearing (pillow block), selecting the electric motor, selecting the shaft, and selecting the voltage regulator. . The testing phase has undergone several testing stages and the results are as planned. The tool that has been made can be operated effectively and obtain results as planned, and its operation is very easy.

Abstract

Investment decisions are a complex process involving risk evaluation, market analysis, and investment return projections. In the decision-making process, investors sometimes show irrational behavior because they have cognitive limitations and previous investment experience so investors are exposed to overconfident behavior. This research used 178 samples consisting of investors who had investment experience of at least 1 year. The research carried out instrument testing and used the common method bias (CMB) testing procedure. The analytical method in the research uses simple linear regression. The results of testing the research hypothesis obtained positive and significant results of overconfidence bias towards irrational investment decisions The moderating role of sharia sharia considerations on the relationship between overconfidence bias and unsupported investment decisions. This research reveals that overconfidence can have a positive influence on irrational investment decision-making. Investors who tend to have excess confidence in their knowledge and skills in analyzing the market tend to make investment decisions that are more impulsive, less rational and sometimes ignore risks significantly. Future research is recommended to further investigate the mechanisms behind the relationship between overconfidence and irrational investment decision-making, as well as involving a wider sample to obtain stronger generalizations.

Abstract

The inspection train is specialized equipment used for examining railway tracks, transporting personnel, and carrying work equipment. The inspection train must be equipped with operational tools, monitoring equipment, and work comfort equipment. One of the comfort equipment is air circulation control, which should provide comfort to the personnel while working. Factors influencing the air temperature inside the inspection train include the number of passengers and duration of door opening. This research employs the Design of Experiment data processing method, with the data analyzed using a 2-factor factorial design experiment, with the assistance of Minitab software to understand the influence of the number of passengers and the duration of door opening-closing on temperature changes inside the inspection train. The result obtained from Minitab analysis indicate that the number of passengers has a significant influence on temperature changes inside the inspection train, accounting for 5.2% of the variation. On the other hand, the duration of door opening-closing does not have a significant effect on temperature changes. Additionally, the interaction between the number of passengers and the door open-close duration does not have a significant influence on temperature changes inside the PPI Madiun Inspection Train.

Abstract

Piping systems are very important in industry, especially in industries related to fluids such as oil and gas industries. Some disturbances in a production or distribution process often occur due to problems in the piping system. One of the serious problems in piping systems is the flow-induced vibration. This vibration problem if not handled properly will cause damage to the structure of the piping system and related components such as pumps or other fluid machines. In this study, the influence of fluid characteristics and the type of support on the vibration pattern (mode shape) will be investigated experimentally. Fluid characteristics are expressed in air and liquid fractions. Two types of pipe support are simply supported and clamped supported in detail investigated. The shape mode of the pipe vibration that occurs is measured as a function of fluid characteristics and support type. The measurement results are experimentally then compared with the results of simulations conducted with Finite Element Analysis. The results of this study indicate that clamped support makes the pipe vibrate with a higher frequency, while fluid flow with a higher liquid fraction provides a higher vibration level.
