Abstract

In the digitalization and automation era, the internet has become an inseparable part of human life It provides a place for devices that are connected and can be controlled wirelessly through a network infrastructure, which is called the internet of things (IoT). In this research, the dual mode system of smart home based on IoT is proposed. In this system, the smart home can be controlled both manually and automatically. The key component for the proposed system is the relay mode which can be controlled to select the mode. The hardware implementation was done to test the proposed system with good result. Blynk app is used to control in automatic mode with virtual switch. When the manual mode is selected, the automatic mode is turned off and vice versa.

Abstract

The growing demand for energy has an impact on the development of environmentally friendly renewable energy. The sun is energy that has the potential to be used as electrical energy through light energy and heat energy. Recently, research interest related to photovoltaic performance has increased. Several studies have investigated the effect of panel cooling on photovoltaic performance. In this study, the use of exergy solar panels is considered to improve performance by adding a thermoelectric system. Research work related to photovoltaic testing with thermoelectrics at low temperatures has not been carried out. Therefore, experimental methods to obtain temperature profiles and simulation methods to see the power potential generated from thermoelectrics have been carried out. The experimental method is carried out using mono-crystalline panels with type K sensors to retrieve temperature data and data acquisition as deviations from the current, voltage, and temperature results of the panel. The simulation model was carried out using the ANSYS software. Tests are carried out, taking into account the effect of back panel temperature on system performance. The results showed that the photovoltaic temperature fluctuated due to the influence of cloud cover, the highest photovoltaic temperature was 57°C, and the lowest temperature was 30°C. The maximum power produced by photovoltaic is 39.8W. It is then applied to the thermoelectric simulation based on the highest temperature, and the maximum power value is 1673.4 mW. This photovoltaic-thermoelectric generator system produces a 4.2% increase in power value over conventional photovoltaic systems. The findings in this study can be used as a reference for all types of low-temperature photovoltaic-thermoelectric systems. Doi: 10.28991/CEJ-2022-08-07-02 Full Text: PDF

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

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.
