Abstract

Indonesia saat ini sangat bergantung pada sumber energi tak terbarukan seperti minyak, bahan bakar fosil, batu bara, dan gas alam untuk pembangkit listrik. Namun, penggunaan energi terbarukan seperti tenaga surya semakin meningkat sebagai alternatif yang lebih ramah lingkungan. Untuk mengoptimalkan penggunaan energi surya, diperlukan sistem pemantauan real-time yang dapat memantau kinerja panel surya tanpa pemeriksaan manual. Penelitian ini merancang dan menguji sistem pemantauan panel surya berbasis IoT menggunakan platform Ubidots. Sistem ini menggunakan sensor seperti sensor tegangan DC, sensor arus ACS712, sensor suhu DHT22, dan sensor iluminasi cahaya BH1750 yang terhubung ke mikrokontroler ESP32. Pengujian dilakukan dengan mengambil pengukuran sensor setiap 5 menit. Data sensor dikirim ke platform Ubidots melalui koneksi internet untuk ditampilkan dan dianalisis. Pengujian menunjukkan bahwa sistem ini dapat secara akurat memantau parameter utama panel surya seperti tegangan, arus, daya, suhu, dan iluminasi cahaya secara real-time. Pengaruh iluminasi cahaya terhadap keluaran tegangan, arus, dan daya juga dianalisis. Pengujian juga dilakukan untuk mengetahui tingkat akurasi sensor-sensor yang digunakan, dengan hasil akurasi sensor tegangan sebesar 98,02%, sensor arus sebesar 91,89%, dan sensor suhu sebesar 95,79%. Secara keseluruhan, sistem pemantauan panel surya berbasis Ubidots ini memberikan informasi yang akurat dan komprehensif tentang kinerja panel surya, membantu mengoptimalkan penggunaan energi surya.Indonesia saat ini sangat bergantung pada sumber energi tak terbarukan seperti minyak, bahan bakar fosil, batu bara, dan gas alam untuk pembangkit listrik.

Abstract

In this research, we intend to build a floor-based power plant that produces energy using a mechanical generator drive. The drive system uses a two-gear transmission system with a different number of teeth, resulting in varying torque and speed. The large gear will stick directly to the floor, causing it to spin when the floor is stepped on, and then the small gear will spin the generator quickly. The buck and boost selector systems are powered by fluctuating voltage from the generator. If the voltage produced by the generator is greater than 5 V, the system will reduce it; otherwise, the system will increase the voltage. This selector system uses several modifications of the current circuit between rectifiers, which function to rectify the generator output when the generator rotation changes, a voltage divider is useful for dividing the generator output voltage. The pressure before and after the selector system was measured by applying force on the floor to 15 people with varying loads. The result shows that the buck and boost selector system can work properly, and the nominal output voltage of the generator is around 5 V as needed.

Abstract

The agricultural irrigation system is extremely important. For optimal harvest yields, farmers must manage rice plant quality by monitoring water, soil, and temperature on agricultural fields. If market demand rises, traditional rice field irrigation in Indonesia will make things harder for farmers. This modern era requires a system that lets farmers monitor and regulate agricultural fields anywhere, anytime. We need a solution that can control the irrigation system remotely using an internet of things (IoT) device and a smartphone. This study employed the Ubidots IoT cloud platform. In addition, the study uses soil moisture and temperature sensors to monitor conditions in agricultural regions, while pumps function as irrigation systems. The test results indicate the proper design of the system. Each trial collected data. The pump will turn on and off automatically based on soil moisture criteria, with the pump active while the soil moisture is less than 20% and deactivated when the soil moisture exceeds 20%. In simulation mode, the pump operates for an average of 0–5 seconds of watering. The monitoring system shows the current soil temperature and moisture levels. Temperature sensors respond in 1-3 seconds, whereas soil moisture sensors respond in 0–4 seconds.

Abstract

In 2023, crime cases in Indonesia reached 105,133. Cases of theft with aggravation dominate the majority of cases. Everyone is concerned about safety, but doors are typically opened and closed using physical keys. This is vulnerable to being tampered with with fake keys, which can lead to house break-ins and theft. In this research, we propose a fingerprint-based wireless door lock design using Arduino and a smartphone. We offer this solution as a preventive measure to reduce the high rate of theft in homes or other buildings. The devices used are Arduino UNO R3, fingerprint sensor, HC-05 Bluetooth module, buzzer, and door lock solenoid. The results of the fingerprint-based wireless door lock using Arduino and a smartphone can function well, with an average response time of 1.20 seconds. Furthermore, testing the HC-05 Bluetooth when sending signals to a smartphone shows that it can read data accurately with an average response time of 1.54 seconds.

Abstract

Energy resilience is a critical requirement in disaster-prone regions, where electrical infrastructure is highly vulnerable to natural hazards and prolonged power outages. Portable and modular solar power systems have emerged as promising solutions for enhancing resilience by enabling decentralized, rapidly deployable, and grid-independent energy supply. This paper presents a comprehensive review of the role of portable and modular photovoltaic-based power systems in improving energy resilience from a power electronics perspective. The review synthesizes recent literature on resilience concepts, system architectures, and converter-based control strategies relevant to emergency energy applications. Particular emphasis is placed on DC-first and hybrid AC/DC architectures, modular converter topologies, battery management systems, and energy management strategies that support reliable and fault-tolerant operation under variable and uncertain conditions. Practical deployment and performance considerations, including scalability, robustness, monitoring, and usability in disaster environments, are also discussed. The findings indicate that well-designed portable and modular solar power systems can significantly reduce recovery time, improve operational continuity, and decrease reliance on centralized grids and fuel-based generators. This review identifies key technical challenges and research opportunities to guide future development of resilient power electronic-based energy systems for disaster response and recovery.
