Abstract

A monitoring system for fuel availability at Base Transceiver Stations (BTS) is an absolute necessity. The fuel availability in the generator set must be guaranteed because it ensures the energy supply and continuous operation. This research purpose is to create a robust and effective sensor that can be monitored in real-time so that industry players can estimate the consumption of fuel at the BTS in a certain period. The novelty of this research is that instead of looking at the amount of fuel consumption/reduction like the previous research, this study focuses on how much diesel availability is in the generator tank. So, calculating fuel requirements and predicting actual consumption are done directly. The sensor is a reed-switch oil level sensor and is connected to ESP32 as the microcontroller. It's installed horizontally and uses an optimum distance between sensors of 2.5 mm to improve the sensor reading's accuracy. The test results of converting voltage values into ADC signals on sensor readings produced a determination coefficient of 0.9987, which showed the reliability of the sensor-level design. The sensor precision test results produced an RSD value of 0.17% and the accuracy test produced an error range of -3% to 2% with an average error value of 1.59%. These results indicate that the designed level sensor has good precision and accuracy. Through this research, the provider can predict and plan their fuel consumption needs for BTS power supply and increase the Domestic Component Level in the sensor industry.

Abstract

In the current era of globalization, technology has become an integral part of people's lives. Automatic car washing is one example, offering services with the best quality, short processing times, and high efficiency. Control devices such as the PLC Outseal Mega V2, proximity sensors, solenoid control valves, gearbox motors, limit switches, fans, and buzzers are used in the automatic car washing process, resulting in cleaner and more well-maintained vehicles. Cars are very popular all over the world. Every year, various car manufacturers produce interesting and attractive car variations at affordable prices for people from different walks of life, which is the result of automotive technological advancements that drive an increase in the number of cars produced every year. As the demand for car wash services continues to increase along with the growth in the number of vehicles available in the city, the car wash business is a good investment opportunity in Pontianak

Abstract

The Department of Electrical Engineering has a Solar Power Plant (PLTS) in the robotics laboratory; however, its utilization is not optimal and is still highly dependent on electricity supplied by the national electricity grid, which poses risks such as unexpected power outages. This research aims to optimize the utilization of renewable energy through an Internet of Things (IoT)-based automatic control system. This system uses an Arduino Uno as the main microcontroller and an ESP32 to transmit data to the ThingSpeak platform. The PLTS serves as the main power source, while the PLN serves as a backup. The system automatically switches the power supply to PLN when the PLTS battery voltage drops below 10.8 V and switches back to the PLTS when the voltage exceeds 13.2 V. Data such as battery voltage, load voltage, current, and load power are displayed on an I2C LCD and visualized in ThingSpeak. Test results show that the system operates as designed, with sensor readings in accordance with manual measuring instruments, and the power supply switching occurs stably in just 1 second. After two days of testing, the system successfully reduced dependence on PLN and maximized the utilization of solar power to power student laptops in the robotics laboratory.

Abstract

The employees' presence is an important factor for an institution, which is relate to discipline and has an impact on the employee's performance.   Therefore, it is necessary to have specific data collection to record presence, absenteeism, and work activities that has done every day so that employee performance record in real-time and proper. There are many ways that can be done to achieve a good presence information system, one of them is using computer and mobile phone technology which is implemented with a website-based presence application. At the Pontianak State Polytechnic, finger print machine used in the presence process system, but it is still lack in efficiency and effectiveness in data collection, data retrieval as well as data recap calculations, which require a relatively long time. Besides, the bigger risk of error and loss of presence data.   Based on problems, a Web-Based Presence Application Development Information System created at the Pontianak State Polytechnic. The research method used in data collection, which includes research methods, interviews and literature. While software development uses a waterfall model which includes requirements analysis, design, coding, testing and implementation. This web-based presence application can provide convenience in the employee presence process, data search and presence recap calculations, and minimize loss and errors in recording employee presence data. Based on web-based presence application testing and evaluation to thirty-four employees of Pontianak State Polytechnic, it stated that the web-based presence application is suitable for used by all employees of Pontianak State Polytechnic.

Abstract

The current study aims to create an automated scoring system for archery target board using computer vision technologies. As archery has develop from a traditional practice to a competitive activity, the scoring procedures have become a crucial element. While the current manual scoring procedures are fallible and can be challenging for organizers. This study offers a solution to this issue by using YOLO v8 (You Only Look Once) architecture for real- time arrow recognition and scoring. The development process consists of dataset collecting, picture pre-processing, model training and implementation using 2 photos of the target boards with arrows. The computer processes the scores by calculating the distance from the center of the arrow to the selected scoring zones using Euclidean distance. System testing established a baseline accuracy of 67%. While users noted the system's processing efficiency (speed), this accuracy level highlights significant room for improvement. The results demonstrate the potential for applying computer vision to automate the archery scoring system, while simultaneously emphasizing the critical need for advanced model performance enhancements. This study serves as a preliminary step in exploring automated sport technology, expected to contribute to future refinements of the archery scoring system.
