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.

Abstract

The measurement of sea level is important in oceanography, as it provides critical information about the ocean environment, including tides, currents, and water temperature. This study aimed to develop an IoT-based sea level monitoring device that can accurately measure sea level and transmit the data in real time. The device consisted of various components: an ESP32 Microcontroller, a GSM Module, an MS5803-14BA sensor, and a battery. The components were assembled on a PCB board and placed inside a waterproof box to protect the electronics from the ocean environment. The field test was conducted for 17 hours at the Tanjungpinang Class 1 Navigation Office Port, and the data was monitored through the Ubidots platform. The results showed that the device accurately measured sea level, with an RMSE value of 0.69 cm and an accuracy rate of 99.47%. However, the field test also revealed data transmission issues, with 18.81% of the data not being sent to the server. This low data transmission rate may have been due to low RSSI levels and issues with operator signal quality. Further research is needed to understand the reasons behind these data losses and to improve the device's overall performance. This study demonstrated the feasibility of using an IoT-based sea level monitoring device to accurately measure sea level and transmit the data in real time. It provides valuable information for further development and improvement of sea level monitoring systems.

Abstract

Sensor Light Dependent Resistor (LDR) merupakan salah satu jenis sensor yang umum digunakan dalam pengukuran intensitas cahaya. Pada penelitian ini, dilakukan analisis perbandingan performa sensor LDR pada ukuran fisik 5mm dan 10mm dalam pengukuran intensitas cahaya. Pengujian dilakukan menggunakan mikrokontroler ESP32 dan kalibrasi dilakukan dengan membandingkan hasil pembacaan sensor LDR dengan pembacaan dari luxmeter. Hasil pengujian menunjukkan bahwa kedua ukuran sensor LDR memberikan respons yang sensitif terhadap perubahan tingkat intensitas cahaya. Sensor LDR 5mm cenderung memberikan pembacaan yang lebih tinggi pada intensitas cahaya rendah hingga menengah, sementara sensor LDR 10mm memberikan pembacaan yang lebih tinggi pada intensitas cahaya tinggi. Selain itu, pengujian juga menghasilkan persamaan eksponensial yang dapat digunakan untuk mengkalibrasi sensor LDR dengan akurasi yang lebih baik.

Abstract

Measuring sea surface height in open waters is very important for understanding tidal patterns and ocean wave dynamics. Most of the instruments currently used are based on pressure or acoustic sensors and are generally placed on the coast, making them less effective for measurements in open waters. This research develops a sea surface height measurement system based on the U-Blox NEO-8M GPS, which is placed on a buoy to obtain real-time elevation data. This system consists of an Arduino Mega 2560, a GPS U-Blox NEO-8M, and a Micro SD storage module. The measurement data were analyzed using the Fourier method to identify the main components constituting the sea surface height. The test results show a Mean Tide Level (MTL) of 4.27 m, a High-Water Level (HWL) of 11.30 m, and a Low Water Level (LWL) of -6.90 m. Fourier analysis revealed eight main components that make up the sea surface height pattern, with the dominant component having a wave period of 4.29 hours and an amplitude of 6 m. The comparison between the measured data and the Fourier model resulted in an average difference of 1.0798 m, likely caused by the influence of satellite signals, multipath, and atmospheric conditions. The results of this study indicate that the GPS NEO-8M can be used as an alternative for monitoring sea surface height in open waters, although it still requires accuracy improvement through signal correction techniques and more precise geoid references.
