Abstract

Vibration in the vehicle body is an important factor that needs to be considered when using a vehicle. This is important because vibration can affect driving comfort and safety, both for the driver and passengers. The less vibration there is, the more comfortable the vehicle is to drive and ride. The aim of this research is to determine the variation of the coil spring on vibration speed. In this research, the approach used is quantitative with an experimental type. The independent variables include variations in coil spring diameter, namely 9 mm, 11 mm, and 13 mm, as well as coil spring length, namely 130 mm, 180 mm, and 230 mm. The dependent variable analyzed is vibration speed. Data was obtained using a coil spring load test tool and a Vibration meter to measure vibration speed. The research results show that the interaction between the diameter and length of the coil spring influences the vibration speed. The highest vibration speed was found in the coil spring with a diameter of 9 mm and a length of 230 mm, while the lowest vibration speed occurred at a diameter of 13 mm and a length of 130 mm. An interaction with a diameter of 13 mm and a length of 130 mm indicates the optimal coil spring size.

Abstract

The heading machine is a critical type of machine used in the production of header tubes. If a failure occurs during the production of header tubes, the product cannot proceed to the next process and must be discarded. However, this machine frequently encounters component failures that require halting the machine for repairs, which is detrimental to the company. This research aims to enhance the machine's reliability by identifying the critical components and scheduling appropriate maintenance based on the heading machine's needs. The research method used is RCM, which includes collecting data on machine downtime and repairs, creating an FMEA table, identifying critical components, calculating TTF and TTR, determining component distribution patterns, establishing parameters, calculating the reliability of critical components, and scheduling maintenance. The research findings identified the critical components as conical spring for orifice and jaw for thread. The calculation of the reliability value using the Weibull distribution equation with scale and shape parameters for the conical spring for orifice components are 1001.78 and 1.12285, respectively. For the jaw for thread component, the scale and shape parameters are 532.083 and 1.33233, respectively, based on values derived from statistical software. As a result, the maintenance schedule should be set when the reliability value of the conical spring for orifice and jaw for thread reaches 0.5 at (t) 720 hours or 30 days, and (t) 390 hours or 17 days, respectively.

Abstract

Lightning overvoltage is a periodic overvoltage caused by external causes. An arrester is equipment that protects installations from overvoltage disturbances due to lightning strikes or electrical surges. The transformer functions to distribute electrical power by increasing or decreasing the voltage at the substation. This research focuses on substation equipment, namely the type 3EP 2150-2PL3 arrester connected to a 100 MVA IBT Transformer. Good protection is obtained if the arrester is placed as close to the transformer as possible. Therefore, this distance is determined so that protection can take place properly. The distance between the arrester and the transformer used at the Keramasan 150 KV substation is 5 m. while from the calculation results it is 22.5 m. based on SPLN 7: 1978 that for a 150 kV system the distance between the lightning catcher and the transformer does not exceed 80 m. This means that the distance between the arrester and the 100 MVA IBT Power Transformer is still within the limits set by PT PLN. The continuity of the spark that occurs in the arrester is still within safe limits and in accordance with mathematical analysis.

Abstract

This study aims to analyze the importance of applying professional ethics in civil engineering for decision-making related to safety, health, and environmental risks (K3L). This is crucial because, like other professions, civil engineering is a complex and intricate field that requires not only engineers with good technical skills but also sound decision-making abilities. The decision-making process significantly impacts the execution of infrastructure projects. Professional ethics serve as a guideline for engineers in making decisions that consider K3L. The issue is that decision-making is not solely based on technical skills but also on other soft skills such as emotional control. This study found that emotional intelligence (EQ) can influence the decision-making process of engineers. The higher an engineer's emotional intelligence, the better their decision-making regarding K3L risks. This is also related to engineers adhering to the professional code of ethics. Furthermore, good decision-making processes are expected to promote sustainable infrastructure development.
