By integrating advanced computational tools, the simulation emulates intricate sorting processes, enabling precise decision-making akin to human judgment. This innovative methodology offers a promising avenue for improving fruit sorting efficiency and product quality in agricultural industries. This simulation system uses loadcell sensors, color sensors and PIR sensors as input. These inputs are used to control three servos and one DC motor. The fuzification process is carried out on both the input and output sides. Based on the results of the fuzification process, eighty-one rules were obtained and a fuzzy inference process was carried out using the intersection method. After carrying out the fuzzy inference process, it is continued with the defuzzification process. The result of the defuzzification value on the quality output is 7324.99 in the high set and the result of the simulation of the quality output value is 7250 in the high set. Thus, the accuracy level of the simulation's results is 98.98%. The simulation results show that the system is able to sort low, medium and high quality Solanum lycopersicum fruit.

Abstract

This research basically started from a gradual power outage carried out by PLN. From this power outage, it is very troubling for the community, both industry and household customers. Load imbalances on electric power distribution transformers always occur and these imbalances occur due to unequal use of electrical energy. As a result of the imbalance of the load, current flows in the neutral transformer. The current flowing in the neutral conductor of this transformer causes losses, namely losses due to neutral current in the neutral conductor of the transformer. The losses contained in the transformer are power loss, core loss and copper loss. In analyzing problems using mathematical models include equations of transformer load imbalance, power losses and efficiency. After analysis, it shows that the transformer is in an unbalanced state where if there is a large load imbalance, the neutral current that appears is also large. The efficiency of the transformer will be even greater if the difference between the inlet and outlet power is small. The power loss occurred 1.98533 kW and the efficiency was 97.06%.

Abstract

This research presents a colour-based object detection system utilizing the HSV colour space and a decision tree model. Achieving an overall precision, recall, and F1-score of 0.98, the system demonstrates robust detection capabilities across various cube colours: blue (0.87-0.89), green (0.87-0.92), yellow (0.74-0.80), red (0.77-0.89), and purple (0.89-0.94). Additionally, the performance evaluation of a robot arm in object manipulation reveals an 80% success rate and a 20% failure rate. Testing across five trials per colour shows successful identification and manipulation distributions for blue (4 successes, 1 failure), green (4 successes, 1 failure), yellow (4 successes, 1 failure), red (4 successes, 1 failure), and purple (5 successes, 0 failures). These findings suggest potential applications in industrial automation tasks requiring reliable colour-based object classification and manipulation, albeit with opportunities for further enhancement to minimize failure rates.

Abstract

PLTB is a renewable energy solution that can reduce dependence on fossil fuels and reduce greenhouse gas emissions. To ensure operational efficiency and reliability, a monitoring system is needed. The monitoring system used in this paper consists of sensors integrated with Arduino to collect real-time data on wind speed, output voltage, current and operational conditions of Tingspeak-based turbines. The data collected by the sensors is sent to the Arduino Uno, which then processes the data for further analysis. Implementation of this Arduino Uno-based monitoring system also allows early detection of potential problems, so that preventive action can be taken to increase efficiency. The results of this research show that the factors that influence the performance of wind turbines are the voltage and current. So for this reason, a tool was created that can monitor and display the amount of voltage and current produced by the Wind Turbine. This tool uses the PZEM-004T sensor to measure current and voltage. The sensor measurement results are processed by the Arduino Nano R3 and then displayed on the LCD and ESP-01 chip to WiFi, then the data will be sent to the Thingspeack cloud server to display the current and voltage

Abstract

Digital technology continues to develop until now such as in Industry 4.0. In the industry, many still use conventional systems such as Induction Motor Starters using the Direct on Line (DOL) System. This study aims to build a system to be able to upgrade conventional systems to digital-based systems. The method used is testing by making a design and then comparing the data obtained to see the response time. From the results of the study, the system can work well. Both testing on conventional systems and online systems. In conventional systems, the system works faster with an average response time of less than 1 second, while with an online system, the response depends on the internet network used so that an average of 1.6 seconds is obtained. In addition, the results of testing using internet of things software show that the system is integrated between conventional systems and digital systems where when the induction motor is ON, a current reading of around 60A will be obtained on the IoT software display and when the motor is OFF, the current reading will drop to close to 0 Ampere.
