Electrical machinery plays a very important in industry and in everyday life hari. Exsitasi or starting a means used by man to ignite and drive the electrical machinery. The way or starting exsitasi electrical machines taken by man to get a good efficiency power efficiency and torque efficiency. Thus it takes a piece of equipment that is capable of performing exsitasi electrical machines with a small power with big torque. Inverter or more commonly known as VSD (Variable Speed Drive) is one option which is used in making exsitasi or starting the electric machines. The inverter is able to perform exsitasi electric machines both single phase and 3 phase with prefix absorbs very little power and have very besar.Contoller torque inverter done so fine that almost did not happen rebound flow and speed that can cause damage to the machines The electricity nor the couple or connecting circuits. In the world of industrial inverter controlled semi-automated and automated by the semi-automatic circuit. Automatic performed by a series of contactors and relays, while the control is automatically done by the PLC (Programmable Logic Control). Arduino can be used as a substitute for controlling performed by contactors, relays and PLC. Arduino able to control the start-stop, round forward and reverse rotation and control the motor rotation speed can be displayed in the display LCD (Liquid Cristal Display)

Monitoring electrical energy in the residential sector is necessary because the current use of electrical energy is less effective and is used very excessively and consumes more electrical power. So far, electrical power usage can only be seen through a kWh meter and only shows the cumulative amount of electrical energy used. However, the design limitations of analog panels only display aggregate consumption data, not real-time consumption data and allow direct monitoring in the field as well as manual recording, so more power is required and the process takes a long time. This research aims to design a real-time measurement system that is capable of monitoring electrical energy parameters for buildings in the residential sector for solar cell-based plants, so that consumers can monitor electricity consumption in real time via the internet. The research methodology is an experiment carried out using the monitoring system design method. Through a research scheme, collaboration with industry is proposed for 1 year with the first stage being hardware design, second being software programming. Hardware and software are connected so that the information presented can be accessed directly at that time. This device is designed to replace manual and conventional electrical energy measurement systems. The research results that will be obtained are a design for a real-time electrical power consumption monitoring system in the housing sector. The output is information on electrical energy consumption through off-line and on-line application media which is displayed on a desktop application on a computer, where the data delivery system is via communication

Solar Power Plants (PLTS) have become one of the solutions to meet the need for clean and sustainable energy. However, like other electrical systems, PLTS is also susceptible to disturbances and problems that can interfere with its performance and reliability. This study aims to design and build a voltage and current protection system at the PLTS inverter output to protect the 1-phase induction motor from damage due to unstable voltage and current. The protection system used is Over/Under Voltage Protector, and MCB for overvoltage and undervoltage protection and load current limitation, in order to protect electrical equipment connected to the PLTS system. The test results show that the protection system implemented on the Inverter Output can protect against overvoltage above 250 V, undervoltage below 185 V, and overcurrent.where if this happens then the electricity supply to the load will be automatically cut off

The type of inverter used greatly affects the efficiency of the PLTS in distributing electrical power to the load to be used. The use of an inappropriate inverter type will cause electrical equipment to quickly become damaged [4]. This study was conducted to help determine the type of inverter that is more appropriate for use in a PLTS system with inductive and resistive loads, so that the quality of the electrical power produced is maximized. This study compared the 1000 Watt Pure Sine Wave Inverter and the 1000 Watt Modified Sine Wave Inverter by measuring the waveform, voltage output value, current output value, power output value, voltage Total Harmonic Distortion (THD) value and current Total Harmonic Distortion value. The final results of the study showed that the Pure Sine Wave Inverter was superior in producing output power, had lower voltage and current distortion values and could produce output waves with a pure sine shape

This research is motivated by the low quality of learning in various educational units, one of the causes of which is the gap between curriculum design and classroom implementation. A good curriculum will not have a significant impact without effective implementation by teachers. Therefore, curriculum implementation plays a strategic role as a link between macro-level education policies and classroom learning practices. This study aims to analyze the impact of curriculum implementation on learning quality, identify supporting and inhibiting factors, and formulate strategies to strengthen learning quality. The method used is descriptive qualitative, using observation, interviews, and documentation techniques with teachers, principals, and elementary school students. The results show that the implementation of a flexible curriculum, such as the Independent Curriculum, encourages a shift from teacher-centered to student-centered learning, which increases student motivation and engagement through project-based learning and authentic assessment. However, teacher preparedness, limited infrastructure, and administrative burdens remain major obstacles. Authentic assessment has been shown to improve students' critical thinking skills and creativity, but requires consistent managerial support. The implication is that improving the quality of learning must be accompanied by strengthening teacher competency, the availability of resources, and adaptive school management so that curriculum transformation has a real impact on the quality of national education
