Abstract

This study investigates the optimization of tungsten inert gas (TIG) welding parameters for joining dissimilar metals, specifically ST37 low-carbon steel and SUS 304 stainless steel, using the Taguchi L9 experimental design. The welding parameters evaluated include welding current (45-65 A), tungsten electrode diameter (1.6-2.4 mm), and shielding gas flow rate (12-18 LPM). The aim is to enhance joint integrity and mechanical properties by systematically analyzing the influence of these parameters on hardness and tensile load (TS loads). Hardness testing revealed that the weld zone exhibited the highest hardness, followed by the heat-affected zone and base metal. Tensile testing showed that the highest TS loads of 341 kgf were achieved at 45 A, 1.6 mm electrode diameter, and 12 LPM gas flow rate. Signal-to-noise ratio analysis and analysis of variance (ANOVA) indicated that welding current had the most significant influence on hardness and TS loads, with contributions of 39% and 41.27%, respectively, followed by electrode diameter (17% and 36.42%). In comparison, the gas flow rate had the least impact (45% and 22.31%). However, ANOVA results showed that none of the factors exhibited statistical significance (P > 0.05). The findings contribute to the field of welding engineering by providing optimized TIG welding parameters for ST37-SUS 304 joints, enhancing their reliability in various industrial applications such as automotive manufacturing, oil and gas, and power generation, where durable and corrosion-resistant welds are crucial.

Abstract

RPM measurement is a crucial measurement tool for assessing a machine's rotation quality and ensuring that it meets the DC motor manufacturer's specifications. The quality of rotation of electric motors and combustion motors can both be observed through RPM measurements. The precision with which the LM393 sensor measures the rotation of a DC motor engine is the problem formulation in this study. Thus, the purpose of this study is to evaluate the rotation measurement accuracy of the LM393 Microcontroller sensor and compare it to a traditional tachometer. In order to conduct rotational variations on the DC motor, the following voltages will be applied: 0.93V, 2.83V, 4.25V, 7.05V, and 9.07V. Next, a tachometer and an LM393 microcontroller are used to measure the DC motor rotation. The gathered data will be made available for verification. Based on the measurement results, the corresponding data differences are -5.560 RPM, -1.577 RPM, -2.182 RPM, -3 RPM, and 0.334 RPM. Therefore, measurement validation was done based on the disparity in readings, yielding results of 0.252%, -1.45%, 0.12%, 0.038%, and 0.0725%. Based on validation results showing a presentation of no more than 10%, the LM393 measuring tool for DC motor RPM measurement is deemed valid and suitable for use.

Abstract

A floor-cleaning robot requires a stable and consistent movement to ensure effective cleaning. This study implements a Proportional-Integral-Derivative (PID) control system using Arduino Uno to regulate the DC motor’s speed and rotation. A well-tuned PID system ensures smooth and constant motion, optimizing the cleaning process. Without PID control, the robot’s movement can become inconsistent, reducing its cleaning efficiency. The research focuses on designing and implementing a PID system to achieve constant speed and rotation through programming. The selected PID parameters are Kp = 0.2, Ki = 50, and Kd = 0, effectively making it a Proportional-Integral (PI) controller. Experiments were conducted under two conditions: (1) unloaded motor testing—where the motor’s rotational stability was assessed without external load, and (2) loaded robot operation—where the robot was tested while cleaning a dirty floor. Results showed that the DC motor's unloaded speed was initially 5 RPM, stabilizing at 10.62 RPM. Under load, the robot's speed started at 0.2 RPM, peaked at 6.85 RPM, and maintained an average velocity of 4.85 cm/s. The robot demonstrated consistent motion in forward, left-turn, and right-turn maneuvers, achieving 13-degree rotations in 30 seconds. The robot was able to operate for 30 minutes, maintaining a stable speed between the 3rd and 22nd minute, before declining as battery power depleted. The findings confirm that the implementation of a PI controller effectively stabilizes motor rotation and enhances floor-cleaning efficiency. Additionally, this control method can be adapted to larger-scale robots and various DC/AC motor systems.

Abstract

The purpose of this research is to develop a sales accounting information system at PT Corbec Communication Bandung. After the research was carried out, there were problem factors, namely the data management process which was still simple so that it was possible for errors to occur in recording sales data and errors in the process of calculating sales transactions so that they had to double-check this which made the process of information about sales reports slow. These problems can be overcome by creating a sales accounting information system that will simplify the process of managing sales data so that the information needed will be easily and quickly obtained. This accounting information system is designed using the PHP programming language with MySQL as its database and the development method used is the RAD method. Testing this sales application using blackbox testing. Based on the design results and the results of testing the sales application of PT Corbec Communication Bandung, it can be concluded that the Rapid Application Development method greatly assists the processing of making sales applications more accurate and faster
