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 increasing number of motor vehicles has led to higher fuel consumption, especially among two-wheeled vehicles, contributing to elevated emissions of hydrocarbon (HC) and carbon monoxide (CO). This study investigates the potential of lemongrass oil (LO) as natural additive to reduce exhaust emissions from RON 92 fuel. The LO was extracted via maceration and characterized by its physical properties, including density (0.893 g/mL), viscosity (5.30 mPa.s), and boiling point (222 °C), consistent with pure LO standards. The additive as then blended into RON 92 fuel in concentration of 10 mL, 15 mL, and 20 mL per 1000 mL of fuel to determine its optimal performance. Results showed that a 20 mL addition yielded the highest reduction in HC and CO emissions, respectively 49.76% and 46.24%. Furthermore, engine performance improved, with power increasing by 0.27 HP and torque by 0.21 Nm within an engine speed range of 5200-5700 rpm. These outcomes suggest that LO enhances combustion efficiency and reduces emissions. The findings highlight the potential of LO as an environmentally friendly fuel additive and supprt ongoing efforts to develop sustainable alternatives to conventional fossil fuels in Indonesia.

Abstract

Industrial businesses have employed various robot cars to execute tasks related to goods movement, such as the Warehouse Robot Car, which utilizes a line follower sensor system. However, the substantial electricity consumption poses a challenge due to excessive energy use in robot cars. In light of this issue, the research aims to assess the utilization of mini solar panels in robot cars equipped with 3.3V Li-ION 18650 batteries. The primary objective is to calculate the electricity required to operate a line-following robot car within the designated sector. The approach involves designing robotics and solar panel systems for generating input and output power, including charging measurements. According to the findings, solar panels can charge at a maximum rate of 0.206358 watts for 45 minutes, while the robot can operate at a minimum rate of 0.26 watts for 29 minutes, resulting in a charging efficiency to robot performance of 43.5 percents.

Abstract

Laser marking has become an industrial trend to label a product to avoid problems arising from errors in product placement, labels can also be other markers depending on needs, laser marking can provide good writing prints on steel sheets. However, problems arise due to poor parameter input errors resulting in marking reading results that cannot be read by the scanner machine, this study aims to provide an analysis of the influence of laser marking input variations that can provide good marking quality, to determine the quality of marking, researchers use a Logitech camera assisted by Open CV programming, to see the quality of laser marking results that can be read by the scanner. This research method begins with inputting 6 parameter variations including speed, laser power and laser frequency, then Open CV programming is carried out to obtain image reading quality with color and line recognition, the reading results will automatically display the error level of the study. The results of the study explain the first test with a high error rate due to low input variables so that the reading is not clear, while the error value is 104040 in color recognition and 69024 in lines that are read with a 100% end range. The lowest error value is in the second test with the highest input variable, namely 1309 in black and white color recognition and 1345 in lines with a range of 100%, therefore the sixth test can be read clearly and well.

Abstract

The apar refill machine consists of several components so that the frame of the apparatus requires a strength analysis of the frame. The problem that arises to make a portable apparatus is that there are 2 main components that depend and 1 component that does not depend, so the purpose of this study is with the process of finite element linear static analysis, the results of the frame design can show the reactions that arise due to the existing load, whether the frame is safe to use or not. This research method begins with design, material input, mesh input, boundary condition input and force input. The results show that the reactions that occur are the highest stress of 18,882 N, disspacement 2,450E + 00 mm, strain of 8,182E-05 and safety factor 3,6383 + 12. From these results, according to the mechanical properties reference static linear threshold, the value is still safe at the maximum force threshold.
