Abstract

The charging speed of lithium-ion batteries depends on the applied current, with higher currents resulting in faster charging.  However, higher currents can increase the surface temperature, potentially damaging components or causing safety hazards. This study measured the surface temperature of lithium-ion batteries using the DS18B20 sensor. The TP4056 module was used for currents of 880.9 mA, 982.30 mA, and 1134.40 mA, while the TP5100 module was used for a current of 1323.80 mA. Charging at 1328.38 mA required the shortest time, approximately 3-4 hours. Temperature measurements showed no significant increase across the range of 880.0-1328.38 mA. For 982.30 mA, the first and second measurements recorded maximum temperatures of 34.4 °C and 36.2 °C, respectively. In the third measurement at 1328.38 mA, the maximum temperature reached 35.5 °C. Overall, the temperature variations remained below the maximum safe limit for lithium-ion battery charging.

Abstract

Keselamatan pelayaran kapal nelayan masih menghadapi tantangan akibat keterbatasan perangkat navigasi dan komunikasi. Automatic Identification System (AIS) adalah solusi navigasi yang dapat meningkatkan keselamatan kapal, namun harga perangkat AIS yang tinggi menjadi kendala bagi kapal nelayan kecil. Penelitian ini mengembangkan perangkat AIS Mobile berbasis GPS, sensor tekanan udara BME280, dan GSM (SIM7000E) sebagai alternatif yang lebih ekonomis. Perangkat ini mampu mengirimkan data posisi kapal, arah, kecepatan, tekanan udara, suhu, dan ketinggian tempat ke platform IoT Ubidots secara real-time. Analisis dilakukan terhadap akurasi sensor, efisiensi konsumsi daya, dan keberhasilan pengiriman data yang diukur melalui Packet Delivery Ratio (PDR). Hasil kalibrasi sensor BME280 menunjukkan akurasi 99,7% dengan nilai RMSE 0,0022 hPa. Pengujian lapangan di perairan Tanjung Berakit menunjukkan bahwa perangkat dapat mengirimkan data posisi dengan PDR sebesar 85,5%. Implementasi AIS Mobile ini menawarkan solusi yang lebih terjangkau dibandingkan AIS konvensional, sekaligus meningkatkan keselamatan kapal nelayan melalui pemantauan data navigasi dan kondisi lingkungan secara real-time.

Abstract

To reduce pollution caused by fuel spills during the refueling process, this research designs and implements an automatic fuel filling device on a wooden boat with a capacity of 6 GT. This system consists of the JSN-SR04T ultrasonic sensor unit, an automatic pump, Neopixel-based LED visual indicators, and a microcontroller as the control center. This tool is designed to automate the fuel transfer process from the dock tank to the ship's tank without the need for manual intervention, thereby increasing operational efficiency and safety. Laboratory tests show that the system has high accuracy, with a Root Mean Square Error (RMSE) value of 0.30 cm, equivalent to an accuracy level of 99.39% in measuring the fuel surface height. In field tests on the Sungai Ungar–Batam route, this device was able to fill 75.76 liters of fuel in 9 minutes and 29.15 liters in 3 minutes automatically. The system is capable of detecting fuel levels, activating the pump when needed, and providing real-time visual notifications. The system's performance is affected by turbulence in the tank when the ship is moving, which reduces the stability of the sensor readings. Therefore, the use of sensors that are more resistant to dynamic conditions and the expansion of testing on larger capacity ships will be the next direction for development.
