A 3-phase electric motor is one of the key components in industrial production processes. In industrial activities, electric motors play a significant role in the production process, as almost all machines in the industry use electric motors as their driving force. This type of motor is susceptible to overcurrent, caused either by an overload or excessive current. Common disturbances that may occur in a 3-phase electric motor include: high starting current, overcurrent, overvoltage, undervoltage, underfrequency, and short circuit undervoltage. A protection system is needed to minimize the losses caused by these disturbances, making it essential to conduct a protection system analysis to be installed on the motor. Using the Multi-Function Meter SMART 7KT as a device capable of detecting these disturbances and taking the necessary protective actions, the protection system employs a PLC (Programmable Logic Controller) and HMI (Human Machine Interface) as the interface for controlling and monitoring the protection system on the electric motor, communicated via Modbus RTU. Therefore, this protection system can safeguard the 3-phase electric motor from disturbances such as large starting current, overcurrent, undervoltage (-10% from normal voltage), overvoltage (+5% from normal voltage), and underfrequency. With this developed protection system, the risk of damage to critical or vital 3-phase electric motors can be minimized

Small-scale wind turbines often face challenges related to low energy conversion efficiency and the lack of adequate monitoring and automatic protection systems against fluctuating weather and load conditions. This study presents the design and implementation of an Internet of Things (IoT)-based monitoring and protection system for a Small Vertical Axis Wind Turbine (VAWT). The system utilizes Arduino Uno and NodeMCU ESP8266 microcontrollers integrated with INA219, LM35, anemometer, infrared, and DC voltage sensors. Data acquisition and transmission are managed through Wi-Fi communication and displayed on the ThingSpeak web platform for real-time visualization. Experimental testing demonstrated that the system successfully measured and transmitted voltage, current, power, wind speed, temperature, and rotational speed parameters with an average data transmission latency of less than 3 seconds. The protection mechanism activated effectively under simulated abnormal conditions such as over-speed and over-temperature, automatically disconnecting the load to prevent turbine damage. The measurement accuracy for INA219 voltage and current sensors reached ±0.2 V and ±0.05 A, while temperature detection with LM35 had an average deviation of ±0.8 °C. The results indicate that the proposed IoT-based VAWT monitoring system is capable of providing reliable, low-cost, and real-time supervision suitable for small-scale renewable energy applications. Furthermore, it can be used as a learning prototype in vocational education to understand the integration of renewable energy and IoT technologies.

Technological developments have brought a revolution in the smart home concept, with smart rooms becoming the main focus to increase comfort, efficiency and security. This article explores the concept of a Programmable Logic Controller (PLC) based smart room with Function Block Diagram (FBD) programming. PLCs, which were originally used in industry, were introduced into the smart home environment as a central brain capable of managing and controlling electronic devices. FBD programming, with its visual approach, provides an intuitive programming solution by using function blocks to represent control logic. Through the use of FBD-based PLCs, smart rooms can be effectively automated, including lighting, temperature and security aspects. The advantages of this method include an easy-to-understand programming interface and the ability to design control logic without requiring a deep understanding of programming languages. The research results show that FBD-based PLCs provide an efficient and effective solution to improve the function of smart rooms. This implementation can provide significant benefits in terms of energy management, occupant comfort and home security. Thus, the PLC-based smart room concept with FBD programming marks a step forward in realizing a smart home that is responsive, connected, and can be adapted to the needs of residents.

Sukamaju Hamlet, Sukawangi Village, Pamulihan District, Sumedang Regency, is one of the hamlet that still need guidance. Most of the residents are farmers and breeders. The livestocks mostly are sheep, dairy cattle and beef cattle. The hamlet comunity formed a farmer group, called Tunas Muda. This farmer group has various interrelated problems. Economic problems is the lack of capital. Meanwhile, the problem with infrastructure is that there is no processing machine, and no common location. The problem with management is that they do not have a good organization yet. Meanwhile, problems in marketing are the absence of featured products, and the bargaining power of farmers is very low. Through this community service program, in accordance with the fields of expertise and available resources, a chopper machine has been introduced to the Farmer Group to break the chain of problems. The direct result of this introduction is a decrease of fresh forage feed need by 35%. Meanwhile, another result of this program is the strengthening of management in the form of reorganization to strengthen the management, the preparation of a new division of tasks, as well as the construction of a common cage with a capacity of 20 sheep. With the existence of this common cage, it is hoped that it will improve organizational functions, as well as management efficiency and effectiveness. For the sustainability of this program, continuous evaluation and assistance is needed. The strengthening of organizational and financial management has been able to improve marketing. If last year's qurban season, the farmers group could sell 9 heads, this year's qurbani season could sell 15.

Transformator merupakan komponen utama dalam sistem kelistrikan untuk menyalurkan energi listrik ke konsumen. Dalam pengoperasiannya, transformator sering mengalami gangguan sehingga diperlukan pengamanan dan pengaturan proteksi yang andal guna menjaga kelancaran sistem. Sistem proteksi dirancang untuk memutus arus gangguan yang terjadi, melindungi peralatan dari kerusakan akibat arus gangguan. Salah satu perangkat proteksi utama pada transformator adalah relay diferensial, yang bekerja cepat tanpa memerlukan koordinasi dengan relay lain. Relay diferensial beroperasi berdasarkan perbedaan vektor antara dua atau lebih besaran listrik yang melebihi nilai ambang tertentu. Dalam penelitian ini, digunakan relay proteksi Siemens 7UT5121. Untuk mempermudah pengujian dan analisis gangguan pada pengaturan relay proteksi tersebut, dilakukan simulasi menggunakan perangkat lunak ETAP. Penyetelan relay proteksi dilakukan untuk melindungi transformator apabila terjadi perbedaan arus pada CT sisi primer dan sekunder dalam zona proteksi. Dari hasil perhitungan, diperoleh nilai rasio CT untuk arus nominal (I₁) sebesar 230,94 A dan arus nominal (I₂) sebesar 1905,25 A. Arus sekunder CT dihitung masing-masing sebesar 0,769 A untuk I₁ dan 0,866 A untuk I₂. Pada relay diferensial, arus diferensial tercatat sebesar 0,097 A, sedangkan arus restrain adalah 0,817 A. Hasil analisis presentase slope menunjukkan nilai sebesar 11,18% pada slope 1 dan 23,74% pada slope 2. Nilai setting arus diferensial yang diperoleh adalah 0,379 A. Relay tidak akan bekerja jika gangguan terjadi di luar zona proteksi, sehingga memastikan keandalan sistem proteksi transformator
