Abstract

Tanaman stroberi memerlukan kondisi lingkungan tertentu agar dapat tumbuh dengan optimal, yakni suhu yang dingin dan lembab. Oleh karena itu, dibutuhkan sistem yang mampu mengontrol suhu, kelembaban udara, dan kelembaban tanah secara otomatis. Sistem ini memanfaatkan sensor kelembaban tanah (soil moisture sensor) untuk mengukur kelembaban tanah, serta sensor suhu DHT22 untuk mendeteksi suhu udara di dalam greenhouse. Data yang diperoleh dari sensor-sensor tersebut diolah oleh mikrokontroler ESP32, yang kemudian mengendalikan relay untuk menyalakan atau mematikan pompa air dan perangkat Peltier sesuai kebutuhan. Jika kelembaban tanah di bawah 40%, pompa air akan diaktifkan hingga kelembaban mencapai lebih dari 70%. Perangkat Peltier dan kipas akan dihidupkan untuk menurunkan suhu apabila suhu dalam greenhouse melebihi 28°C, dan akan dimatikan jika suhu turun di bawah 22°C. Sistem ini juga mengendalikan kipas tambahan untuk menjaga kelembaban udara agar tetap berada dalam rentang yang optimal.

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

Electric bicycles are bicycles that are battery powered and driven by a motor. Electric bicycles can utilize more than one energy source, namely generator energy and solar energy to supply the battery, which is called hybrid energy. Battery charging is limited when it is full to prevent overcharging. Battery charging can be done using several methods, one of which is the Constant Voltage (CV) method. The stage for synchronizing hybrid energy sources is to condition the voltage of both hybrid sources so that the same value is achieved. Conditioning over charge uses an auto cut-off circuit which can cut off the source current if the battery is full, indicated by a Light Emitting Diode (LED). Research shows that battery charging by relying on a boost converter to synchronize the two sources can work very well. The boost converter voltage does not accumulate because both boost converters are installed in parallel. The auto cut-off circuit can prevent overcharging the battery by utilizing a zener diode and relay.

Abstract

The Carolina Reaper chili, known for its extreme spiciness reaching up to 2,200,000 Scoville Heat Units, requires meticulous cultivation methods for optimal yield. This research emphasizes the importance of proper fertilization and irrigation. An automatic drip fertigation system is introduced to address issues such as inconsistent watering and nutrient imbalance. The system employs waterproof ultrasonic sensors, soil moisture sensors, RTC, and a DHT22 temperature sensor, monitored via Internet of Things (IoT) technology. An Arduino Uno controls the timing, soil moisture, greenhouse temperature, and fertilizer liquid level. A relay-operated solenoid valve is used to automatically supply fertilizer and water. The implementation of this system enhances the efficiency of water and fertilizer use, ensures consistent irrigation, and facilitates plant monitoring. This technology has the potential to improve the yield and quality of Carolina Reaper chilies while reducing labor costs and resource usage in modern agricultural practices.

Abstract

This research focuses on developing an IoT-based capacitive sensing system for monitoring water volume in tanks, suitable for specific residential and industrial applications. The main capacitive sensor utilizes a 32 cm x 6 cm x 2 mm aluminum plate coated with resin to protect against moisture and contaminants. Initial evaluations demonstrated high sensitivity and rapid response in detecting liquid levels, with an 8.23% margin of error. However, further evaluation is necessary to address specific aspects such as resolution and response stability. Next steps include refining the design, conducting additional experiments, and optimizing sensor parameters. These findings aim to provide deeper insights into capacitive sensor technology and open new possibilities for its application across various technological contexts.

Abstract

This research aims to develop a prototype of a laboratory-scale wave generator to explore the potential of river wave energy, which has mostly been focused on marine energy due to its significant potential. The device consists of a container measuring 100x22x30 cm, using a servo motor to generate water ripples and an ultrasonic sensor to detect ripple height. Two propulsion methods are employed: simultaneous and alternating, with more varied ripple patterns observed in the alternating method. Changes in the servo motor’s angle produce three thrust levels with different wave heights: slow (1-2 cm), moderate (2.5-3 cm), and strong (3 cm). The findings highlight the renewable energy potential of river wave energy, which can be harnessed sustainably, reducing carbon emissions, dependency on fossil fuels, while enhancing energy security and job creation.

Abstract

Aliran sungai sangat penting bagi sektor pertanian dan perkebunan di Desa Bentunai, digunakan untuk sistem irigasi yang meningkatkan hasil panen. Oleh karena itu, diperlukan sistem monitoring ketinggian air sungai menggunakan PLTS sebagai sumber energi, ESP32 sebagai mikrokontroler, dan sensor ultrasonik untuk mendapatkan data ketinggian air, serta IoT untuk akses jarak jauh. Energi untuk sistem ini diperoleh dari panel surya yang mengubah sinar matahari menjadi listrik dan menyimpan energi di baterai, memungkinkan operasi terus-menerus bahkan di malam hari atau cuaca buruk. ESP32 mengelola sensor yang membaca ketinggian air dan mengirimkan data real-time melalui Wi-Fi ke aplikasi yang digunakan. Hasil dari pengujian menunjukkan persen error pembacaan sensor adalah 0,25% sedangkan hasil pembacaaan IOT dengan thingspeak mengalami delay 23 detik. Hasil pembacaan sensor dengan IOT menunjukkan hasil pembaacaan yang stabil. Hasil pemantauan ketinggian air menunjukkan puncaknya dibulan januari. Dengan sistem ini dapat membantu pemantauan pasang surut air harian.
