Abstract

Motor induksi (atau motor asinkron), yang merupakan motor Arus Bolak-balik (AC) yang paling banyak digunakan di industri, selalu bergantung pada perbedaan kecil dalam kecepatan antara medan magnet stator yang berputar dan kecepatan poros rotor yang disebut untuk menginduksi arus rotor pada belitan rotor. Dengan demikian, motor induksi tidak dapat menghasilkan torsi pada kecepatan sinkron, di mana slip tidak lagi ada. Sebuah motor bila diizinkan, akan memberikan torsi hingga batas maksimumnya untuk memutar bebannya; terutama di bawah rotor yang terkunci atau berat beban peralatan yang dimuat. Nilai batas torsi maksimum berbeda untuk setiap motor induksi AC dan berbanding lurus tergantung pada karakteristik motor. Dalam beberapa kasus, seperti konveyor, mesin bubut bermotor, atau penggerak motor langsung, jika motor dibiarkan menjalankan torsi maksimum, itu dapat menyebabkan kerusakan permanen pada peralatan. Penelitian ini menyajikan desain sistem Variable Speed Drive (VSD) yang memiliki kemungkinan untuk mengukur kecepatan rotor dan mengendalikan torsi motor asinkron berada dalam batas torsi yang ditentukan.

Abstract

The remote-control system on this Unmanned Surface Vessel (USV) or unmanned ship uses Long Range (LoRa) technology. LoRa was chosen because of its ability to transmit data over long distances with low power consumption, making it very suitable for applications in the maritime environment. The control system on the USV is responsible for controlling movement, so it involves several technologies and components that work together to ensure the USV can operate efficiently. The way a USV works involves several systems working together to allow the autonomous vehicle to operate on the water surface unmanned or without direct human intervention. Under Line of Sight (LOS) conditions, the range of LoRa-02 to control unmanned is success rate up to a distance of 100 meters and achieved a 100% for data transmission. However, in the Non-Line of Sight (NLOS) test, there was a decrease in the range of only 70 meters due to obstacles such as trees or other objects. The transmitted data comes from the wireless camera in the form of images with timestamp displayed in real-time. The display from the wireless camera is utilized for visual field monitoring and can be monitored remotely.

Abstract

Sea water pollution is an increasingly urgent global issue, caused by various factors such as industrial waste, household waste, and ship activities. One of the solutions needed to overcome this pollution is the development of a detection system that is able to monitor polluting substances quickly, accurately, and efficiently. This research aims to design and build a microcontroller-based seawater pollution detection system, which can identify various pollution parameters in real-time. This research uses the Research and Development (R&D) method to develop a system consisting of several main components, including a pH sensor, turbidity sensor, Arduino Uno, GPS module, Raspberry Pi 4, USB camera, LiPo battery, and step-down converter. Each component is tested individually before being integrated into the overall system. The results of testing in a real environment show that the system is able to detect seawater pollution parameters with high accuracy. However, there are some errors in data collection, especially in the camera sensor with a percentage error of 32%, turbidity sensor 20%, and pH sensor 24%. Further improvements and developments were made based on the evaluation results to enhance system performance. The resulting system is considered accurate, reliable and easy to use, making an important contribution to efforts to protect seawater quality and mitigate the negative impacts of pollution on the environment and human health.

Abstract

Freon is one of the refrigerants used in refrigeration systems. The refrigeration system has a very important role, namely to preserve food ingredients so that food can last longer. The use of freon is not only used in ships but is widely found in home appliances in refrigeration systems used in freezers, air conditioners, refrigerators, and dispensers. If more freon is used, the negative impact that arises is greater, namely the depletion of the ozone layer and global warming which can have a bad influence on health, the life of living things and the environment. The purpose of this researcher is to create a tool to reduce the negative impact of freon use, namely by using peltier as a cooling medium with environmentally friendly thermoelectric modules. This study uses trial and error methods. Where the trial process is carried out by turning on one of the working push buttons and observing the temperature value. Then it is processed by the control system, namely Arduino Mega which will later provide a PWM output signal to the IRF540 mosfet when the output temperature value is in line with the reference value and vice versa. The test of this tool was carried out by comparing measurements between the author's prototype tool and the standard measuring tool, namely the digital thermometer. Based on the test results, this device can produce a minimum temperature of 140C at 30-minute intervals without any media. The trial using 330ml bottled water can reach a temperature of 170C within 30 minutes in the cooler box. This tool is also equipped with an automatic monitoring system using a PWM signal in the form of a change in fan speed, which is 255 RPS maximum speed and when getting a PWM signal it changes to 50 RPS. The percentage of errors resulting from the comparison of standard measuring instruments and sensor values had the highest and lowest percentages of 2.37% and 0.84% in cold dispersion conditions without charge. Then the highest and lowest error percentages were 1.69% and 0.72% in the state of containing a load of 1 330ml mineral bottle. This ptototype uses data recording using Micro-SD as a data logger.

Abstract

In the era of maritime technology, Unmanned Surface Vehicles (USVs) are becoming the main vehicles on the water surface, controlled from land and capable of transmitting live data. USVs have a wide range of survey and exploration applications, relying on hydrographic knowledge for accurate mapping. USV development has adopted a double hull design, improving stability and wave resistance. Survey data transmission requires advanced technology, with Long Range (LoRa) technology being the solution for long distance data transmission with low power consumption. LoRa utilisation is expected to increase the efficiency of USVs in hydrographic surveys. The research and development (R&D) research method is used as the main approach in this research with the aim of creating and developing USVs that can increase efficiency in hydrographic surveys. The USV is equipped with an RPM sensor and flowmeter used to monitor the movement control of the USV in the waters. In addition, a depth detector is used to monitor the topography of the seabed. In order for this USV to run using a remote control that is controlled from land. The USV drive consists of a BLDC motor connected to the propeller and a servo motor connected to the ship's rudder. Furthermore, the data taken from the sensor is sent via LoRa to be delivered to the ground station. From the USV test results, it was found that the data transmission range with LoRa Ra-02 under Line of sight (LOS) conditions was 340 metres while under Non Light of sight (NLOS) conditions it was around 200 metres. The average speed travelled by USV is 0.616 km/hour in operational survey conditions and can be faster in non-operational survey conditions. The error value of the RPM sensor is obtained at 1.604% with a reading accuracy of 98.936%.

This research focuses on designing an electrical system for unmanned surface vehicles (USV) to ensure optimal performance during survey operations. This USV ship is a catamaran-type ship with a Sonar Deeper depth sensor to know the depth of the water and is equipped with long range (LoRa) as a data transmitter. The USV electrical system design incorporates the use of a 4050 mAh 11.1 V LiPo battery and an iMAX B6AC charger, with evaluations covering battery charging, power consumption, and voltage stability. The trials showed that the battery supported the operation of the USV for approximately 47.8 minutes at a power load of 45.08 Watts. Battery charging showed two main phases: constant current and constant voltage, with a full charge time of approximately 2.7 hours. During operation, voltage consumption showed significant fluctuations, highlighting the need for an electrical system design that maintains voltage stability to improve performance. From the test results, the battery efficiency was found to be 91.29%. These findings emphasize the importance of appropriate component selection and efficient power management to achieve reliable and efficient USV operation. With a deep understanding of the charging characteristics and power consumption, the designed electrical system can ensure more stable USV operation and better performance under various survey conditions.
