Abstract

As the world embraces sustainable energy solutions, energy storage systems are becoming increasingly critical for the effectiveness of renewable energy sources. Batteries have emerged as a promising option. However, to fully harness the potential of batteries, the challenge of cell must be overcome. This review article delves into the evolution of battery active equalizers on the quest for sustainable energy storage solutions. The review begins by exploring the fundamental principles of battery active equalization and its significance in optimizing energy storage system performance and efficiency. Traditional battery management techniques are limited in their ability to address imbalances effectively, making active equalization a compelling alternative. The review provides a comprehensive analysis of early developments and current state-of-the-art active equalization systems. The reviewed article demonstrates successful applications, showcasing how active equalizers can significantly improve energy storage performance and overall system stability. While active equalization offers tremendous promise, it is not without challenges. The review explores how these technologies seamlessly fit with renewable energy sources and grid systems, opening up possibilities for future energy infrastructure. Industry perspectives play a vital role in realizing innovative technologies. Therefore, the review incorporates insights from leading experts, presenting their viewpoints on the adoption of battery active equalizers.

Abstract

The livestock waste in Sambi village has not been utilized for organic fertilizer. In fact, the number of livestock farmers is increasing every year, which has an impact on increasing waste. The purpose of this activity is to provide training and practice in making solid organic fertilizer from livestock waste in Sambi Village, Sambirejo District, Sragen Regency. Organic fertilizer is a form of fertilizer that comes from organic materials, such as animal waste, rotting plant residues, and other natural sources. Making organic fertilizer has the advantage of increasing community income and optimal use of organic fertilizer can improve soil fertility due to excessive use of chemical fertilizers. The majority of Sambi villagers have livestock and also cultivate agricultural crops. Waste has not been utilized for solid organic fertilizer and is still completely dependent on chemical fertilizers that cause physical damage to the soil, besides being expensive and rare. This program provides a package of solid organic fertilizer processing technology so that farmer groups can produce independently. In achieving the success of the program, socialization, training and mentoring have been carried out periodically. The production of organic fertilizer is expected to increase soil fertility and can be sold to increase community income

Abstract

Indonesia, with its tropical climate, possesses substantial solar energy potential. However, traditional monitoring of solar power systems in Indonesia still relies on manual observation, making the process inefficient, time-consuming, and prone to error. To address these limitations, this study proposes the design and implementation of a real-time Internet of Things (IoT)-based monitoring system for solar power plants using the Telegram application as the user interface. The system integrates the ESP32 microcontroller and the Pzem-004 T sensor to measure AC electrical parameters, including voltage, current, power, energy, frequency, and power factor. Unlike previous studies that used platforms such as Blynk or ThingSpeak, this research introduces Telegram as an innovative messaging-based monitoring platform, offering greater accessibility, simplicity, and user familiarity. The monitoring system was tested on a single-phase off-grid solar power setup, utilizing five types of household electrical loads, to validate its accuracy and reliability. The ESP32 communicates with the Telegram bot through Wi-Fi, and users can retrieve real-time data via predefined commands. Experimental results demonstrate high measurement accuracy, with average errors of 0.07% for voltage, 0.1% for current, and 0.08% for power. These results confirm that the system provides reliable data transmission and sensor readings. This work contributes a low-cost, efficient, and user-friendly alternative to conventional monitoring systems, particularly for decentralized renewable energy systems in remote or off-grid areas. The integration of Telegram as a communication medium for energy monitoring adds a novel dimension to IoT-based power system applications.

Abstract

Pengentasan teknologi untuk sektor pertanian berperan vital dalam mendukung swasembada pangan pada era ini. Kelompok Tani (Poktan) Madusari 03 merupakan petani teh yang aktif dalam melakukan pengembangan dan elaborasi teknologi dalam pengelolaan hasil perkebunan. Tujuan pengabdian masyarakat ini untuk mengembangkan teknologi pengeringan daun teh menggunakan sistem IoT (Internet of Thing) dalam mendukung kualitas hasil produksi yang lebih cepat dan terkontrol. Pengabdian ini dilakukan 4 tahap: Persiapan pengabdian, pengembangan teknologi, sosialisasi IoT, dan evaluasi. Berdasarkan program yang telah dilaksanakan, ditemukan bahwa masyarakat dapat mempercepat proses pengeringan teh dibandingkan metode konvensional dan mudah untuk meramu komposisi pengeringan untuk menghasilkan produk yang beragam. Pengabdian ini diharapkan dapat menumbuhkan perekonomian masyarakat melalui pengentasan teknologi kekinian untuk menjadi petani semakin berdikari.

Abstract

Dynamic load variations significantly impact the stability of system frequency, necessitating the implementation of Load Frequency Control (LFC) to maintain frequency stability. In this study, a PID-based control approach is applied to LFC modeling using the Ziegler-Nichols tuning method through the Reaction Curve Method. The test was conducted using the difference of load of 1 p.u. Using these parameters, the optimal PID controller was configured with Kp = 2.97, Ki = 0.78, and Kd = 2.27. The evaluation demonstrated that the system achieved a settling time of 17 seconds and a maximum overshoot of 65.35 Hz. Under various load scenarios, including increasing, decreasing, and fluctuating loads, the LFC system equipped with a PID controller based on the Ziegler-Nichols Reaction Curve Method effectively maintained frequency stability despite significant load changes. These findings confirm that the proposed approach is reliable in preserving system performance under dynamic load conditions.

Abstract

Proyek pengabdian masyarakat ini memberikan bukti bahwa mesin oven dengan dimensi yang lebih besar dapat meningkatkan produktivitas dan efektivitas pembuatan roti. Mesin oven memungkinkan untuk memanggang beberapa jenis roti yang ada pada UMKM Rara Kitchen dengan waktu yang lebih singkat, terutama untuk Bolu Panggang.  Peningkatan produksi roti akan berdampak pada penghasilan UMKM dan juga masyarakat di sekitar UMKM. Peningkatan hasil produksi dapat mendorong terbukanya lapangan pekerjaan baru untuk membantu proses produksi roti di UMKM Rara Kitchen. Produksi roti bolu menggunakan mesin oven dapat mempersingkat waktu pembuatan dari yang awalnya 450 menit untuk 10 loyang menjadi 45 menit. Efektivitas yang dihasilkan menggunakan mesin oven dapat meningkat hingga 900%. Meningkatnya efektivitas produksi membuat keuntungan per bulan naik sebesar 92.8%. Selain itu, dampak lain dari program ini adalah meningkatnya jumlah pembelian bahan baku pembuatan roti di sekitar lokasi UMKM, di mana ini berdampak pada perputaran ekonomi yang lebih cepat pada toko bahan kue dan toko kelontong.
