Abstract

The development of increasingly advanced science and technology has produced many innovations in meeting the needs of mankind. One area that is developing comprehensively is robotic technology, one of which is obstacle avoidance robots which is an example of a device used to improve the safety and effectiveness of human work. This study aims to design and develop obstacle avoidance robots using the PID (Proportional, Integral, and Derivative) method and ultrasonic sensors. Robots are designed to automatically detect and avoid obstacles in their environment by using ultrasonic sensors to measure the distance between the robot and existing objects. The PID method is used to control the movement of the robot based on information received from the ultrasonic sensor with Arduino Uno as the main brain controlling the DC motor. Ultrasonic sensors are used to measure the distance between the robot and obstacles in front of it. The distance data obtained from the ultrasonic sensor is then processed using the PID method to produce a control signal that regulates the speed and direction of the robot's movement. The robot is equipped with an obstacle avoidance mechanism that allows it to change its direction of movement automatically when it detects an obstacle in front of it by testing it in various obstacle avoidance scenarios. The results of the tests that have been carried out show that the robot is able to detect different obstacles with high accuracy and avoid them successfully. The use of the PID method in controlling the robot's movement has proven to be effective in maintaining the stability and accuracy of the robot's movement. This research contributes to the development of robotics and automation technology by presenting an obstacle avoidance robot that can move automatically and avoid obstacles effectively.

Abstract

Electrical equipment often faces various issues, with insulation problems being a major cause of failure. This article investigates the comparative effectiveness of two Partial Discharge (PD) detection methods: using Transient Earth Voltage (TEV) sensors and Resistor-Capacitor (RC) detectors. The study was conducted on a metal box with a voltage level of 6 kV. Data collected included Background Noise (BGN) and Partial Discharge Inception Voltage (PDIV), processed using Microsoft Excel and OriginPro 9. Results indicate a correlation between higher BGN values on TEV sensors and earlier PDIV occurrence on those sensors. Background noise significantly impacts the PDIV threshold, influencing sensitivity and insulation risk potential. While PDIV provides a threshold guideline, correlation with BGN helps illustrate the background conditions' influence on PD measurement outcomes. The study offers insights into the importance of considering noise in PD measurements and formulates recommendations for practitioners to choose appropriate detection methods based on specific environmental conditions and electrical equipment.

Abstract

Tire pressure requirements may vary for different vehicles depending on factors such as the brand, load, and tire type. Inadequate tire pressure can result in suboptimal braking performance. This study aims to examine the impact of tire pressure variations on the efficiency of the main brake and parking brake in vehicles. The brake tester was utilized to conduct experiments on pickup goods vehicles with a GVWR less than 3,500 kg. The findings reveal that tire pressure has a significant influence on the efficiency of the main brake and parking brake. Higher tire pressure corresponds to lower efficiency values for both brakes, while lower tire pressure yields higher efficiency values. It is crucial to raise awareness among vehicle owners about the importance of maintaining proper tire pressure as it directly impacts braking performance and overall vehicle safety.

Abstract

CV YZX is a manufacturing company in the stainless steel hardware sector that specializes in hardware and detailing. This company actively produces for the needs of individual consumers and orders from other companies. One of the problems faced by CV YZX is the use of production machines that are less than optimal at every stage of the production process. Production machine performance that is not optimal can increase the total value of production time (makespan), which in turn can cause delays in completing products and delivery to consumers. This research aims to find the minimum total production time value by applying the Campbell Dudek Smith method to production scheduling. The calculation results show that by applying the First Come First Serve (FCFS) production scheduling method, the company obtained a makespan of 39.64 hours. However, by using the proposed method, namely Campbell Dudek Smith (CDS) in production scheduling, the results of the makespan calculation show a figure of 33.58 hours. A comparison of the two methods shows that the proposed scheduling using the Campbell Dudek Smith method has a lower makespan value compared to the company method (FCFS), resulting in time savings of 6.06 hours or the equivalent of 15,3%.

Abstract

One of the important parts that ensures the availability of electrical energy supplies which takes place from the central power plant and then through the transmission line to distribution to the load is the insulator. However, over time, insulators can experience anomalies such as corrosion. Insulator corrosion can be caused by many environmental factors, including pollution, humidity, high temperatures and exposure to chemicals. Previously, maintenance personnel usually identified the level of corrosion on insulators visually by using their knowledge and experience through routine inspection activities to check the condition of the insulators. This technique, however, takes a long time and is often subjective. Therefore, in this research, the way to detect the degree of corrosion on insulators is by using image processing and using active contour segmentation to determine the degree of corrosion on insulators and using decision trees as a method to create a classification model for the degree of corrosion. This can help reduce reliance on subjective human judgment, increase the effectiveness of the recognition process, and optimize overall isolator maintenance efforts. The application created in this research has a user interface that makes it easier to process images of corrosion insulators. The front page, practice page, and test page comprise this interface. Meanwhile, the results of classification using a decision tree for the low category are in the ratio x1 < 0.082104, the medium category is in the ratio 0.082104 =< x1 < 0.15061, and the high category is in the ratio x1 >= 0.15061 with an accuracy result obtained of 93.33% for test image data and recall and precision values ​​obtained 100% results.

Abstract

The need for electrical energy from year to year influences the need for electrical energy at every level of the general public and industry as electricity users. Because electricity has become a part of life (Roza, 2019). In this case, there are separate challenges that must be faced by every company operating in the electricity supply sector, especially the State Electricity Company (PLN), which is the sole company in serving electrical energy needs. The power generation centers are far from the load center, this results in quite large losses in the distribution of electric power. So, when distributing electrical power through transmission and distribution, voltage drops will occur along the line. The length of the distribution channel from the substation to the distribution transformer or from the distribution transformer to the load (Roza, 2019).
