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

A Gravitational Vortex Water Turbine (GWVT) is an appropriate device to harness the kinetic energy of water to convert it into rotational mechanical energy in low-head. The water flow is directed into a circular basin, which can produce a vortex and can rotate the turbine blades. Turbine performance is influenced by the shape of the blade, so an optimal blade shape is required. Turbine performance is influenced by the shape of the blades, which can rotate optimally. This study aims to determine the effect of adding baffle plates in the blade on the performance of two-stage GWVT using experimental methods. The variation used is the proportion of baffle plate on the runner in the first stage with variations without baffle plate, 25%, 50%, 75%, and 100%. The data taken in the test is the torque and rotation at each additional blade plate. Torque measurement uses a rope brake system, and rotation measurement uses a tachometer. The results of the study showed that the addition of a 50% baffle plate in the first stage can capture the energy of the water vortex more optimally. A baffle plate can increase efficiency by up to 23.15% compared to the blade without the addition of a baffle plate. Doi: 10.28991/CEJ-2025-011-02-011 Full Text: PDF

Abstract

Proyek pengabdian ini telah menunjukkan bahwa mesin pencacah plastik memberikan solusi efektif dalam pengelolaan sampah plastik di kalangan pengumpul barang bekas di Kabupaten Magelang. Mesin-mesin ini memungkinkan pengolahan sampah plastik menjadi bubuk plastik, yang dapat dijual oleh pengumpul barang bekas. Pendapatan yang diperoleh dari penjualan bubuk plastik berfungsi sebagai sumber pendapatan tambahan, sehingga berkontribusi terhadap peningkatan ekonomi para pengumpul barang bekas. Selain itu, penggunaan mesin penghancur plastik juga memberikan dampak positif terhadap lingkungan dengan mengurangi penumpukan sampah plastik yang biasanya menimbulkan polusi. Mesin-mesin ini juga meningkatkan efisiensi operasional, meningkatkan kapasitas pemrosesan dan mengurangi waktu yang dibutuhkan untuk menangani sampah plastik. Pemberdayaan teknologi ini mendorong pengembangan keterampilan dan pengetahuan di kalangan pengumpul barang bekas, sehingga memungkinkan mereka untuk memperluas bisnis daur ulang mereka. Selain itu, keterlibatan masyarakat dalam pengelolaan sampah plastik meningkatkan kesadaran akan pentingnya daur ulang dan pengurangan sampah. Keberhasilan program ini, didukung oleh berbagai pemangku kepentingan, menjamin keberlanjutannya dan menjadi model bagi daerah lain. Secara keseluruhan, mesin pencacah plastik tidak hanya memberikan solusi pengelolaan sampah yang efektif di Kabupaten Magelang namun juga memberikan manfaat ekonomi, lingkungan, dan sosial yang signifikan, sehingga menyoroti pentingnya inovasi dan pengembangan berkelanjutan dalam praktik pengelolaan sampah.

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

Prima Oryza Abadi, a small rice milling and sales business in Krandegan Village, Kebumen Regency, faces challenges in product quality and business legality that limit its competitiveness and business growth. The rice produced has a cloudy color, low cleanliness levels, and many broken grains, resulting in a selling price of only around IDR 11,000–13,000 per kg, far below the market potential of IDR 17,000/kg if quality were improved. In addition, the lack of business licenses, trademarks, and legal entities makes it difficult for partners to access capital, establish cooperation, and build consumer trust. The objective of this program is to increase business capacity and competitiveness through product quality improvement, operational efficiency, and strengthening of legality-based business management. The methods used include socialization, training in rice whitening machine technology, the application of technological innovations with a capacity of 150 kg/hour with a steam atomization system, air drying, and low-speed milling, as well as assistance in obtaining a Business Identification Number (NIB), PIRT Certificate, trademark at the National Intellectual Property Agency (DJKI), and the establishment of a legal entity (UD). The results show a significant improvement in rice quality, as seen in whiter color, better cleanliness, and fewer damaged or broken grains. The machine is capable of efficiently processing 150 kg of rice per hour without the use of chemicals, thus meeting food safety standards. Partners have successfully registered trademarks and obtained complete business legality, enabling direct sales to consumers and market expansion. Management assistance also improved financial management and digital marketing capabilities. Overall, the program successfully improved product quality, competitiveness, and business sustainability, while supporting 2 and 8 and strengthening the local economy.
