In the midst of globalization, energy is a major need in people's lives. These energies are used for various purposes, namely for industry, vehicles, power plants, fuel, and others. The use of electrical energy at the Riau Kepulauan University is mostly used as a teaching and learning aid. One of the tools used is projector as the main tool for delivering material to students. Due to frequent power outages in the city of Batam, it has an impact on the learning and teaching process, especially in the delivery of lecture material for students. The design of Solar Power Plants (PLTS) discusses to the power supply backup if a power outage occur so that the learning and teaching process can still continues. After testing and retrieval of data on this PLTS, the results obtained on average are 16.6 watt and the power supply backup electricity on projector last for 47 minutes.

Urgency of the research. Current trends of distributed generation development in Ukraine indicate a rapid generation in-crease from renewable energy plants. Most developed countries gradually refuse from the fossil fuels use and invest more and more to the “green” energy. Therefore, there is a need for a detailed study of the operation conditions of distributed energy sources due to their instability, as well as the processes that arise in distribution electric networks with diverse types of distributed energy sources. Target setting. In the producing process of power energy by distributed energy sources due to the increase in their num-ber, there are situations where several renewable sources of energy operate to only one system of buses. Thus, such distributive networks acquire the features of a local power system, which complicates the control process of such systems, and also there is a problem with the electricity supply of consumers. Actual scientific researches and issues analysis. The analysis of publications suggests that in literature more attention is paid to studying the operating modes of solar power plants, or small hydroelectric power plants. However, almost no attention was paid to the study of their cooperation work. Uninvestigated parts of general matters defining. Only a few works are devoted to the study of the cooperation of the diverce sources of distributed energy sources in the local electrical systems. That is why, their impact on power distribution networks and on the grid in general has not been studied extensively. The research objective. In this article was considered the influence of asynchronous generators on small hydroelectric power plants on the operation modes of distribution electrical networks, and were investigated the processes that are occurring in local power systems with different types of distributed energy sources. The statement of basic materials. Based on the research results, was developed a computer model of a such system in the PS CAD software environment. Two solar stations and one small hydroelectric power station with an asynchronous generator were connected to the power supply. It was shown the simulation of two modes of operation: a joint operation of a small hydroelectric power station, two solar power stations and a power supply center; a joint operation of a small hydroelectric pow-er plant, two solar power stations and a power supply disconnected. Conclusions. As a result of computer simulation, it is shown that by switching on a small hydroelectric power plant with an asynchronous generator in the case of an emergency shutdown of centralized power supply, it is possible to restore the work of solar power plants, and thus partially or completely restore the power supply of consumers.

Ideal curriculum is the curriculum that consists of something good as the dream of book of curriculum. Real curriculum is real actions that apply in learning and teaching process as the real of the planing curriculum. Curriculum content is what we have to do to the learners and the learning and teaching is a manner of what we will give or teach to the learners. The development of 2013 curriculum is stresset to compeletness of learners thinking, the impressing of curriculum management, the domination and development of material, stressing process of teaching and learning process, and lining appropriate of learning responsibility in order to get the guaranty of appropriate between what we want and what we get. Effected aspect to the implementation of 2013 curriculum raleted directly to the process of learning, namely: teachers’ creativities, learners’ activities, facilities and recourses.Will the 2013 curriculum can be realized by teachers practically in the field? Today, the changing of curriculum reap many responses, some people are pessimistic even declining the curriculum, but at the same time some are appreciative to the curriculum. The changing of curriculum does not affect the changing of the teacher’s method and style to teach. It needs revolutionary change in the practice of 2013 curriculum.

Pandemic Covid-19 brings impactful aspects for several sectors, especially in the education sector. The teaching and learning process has shifted to online learning. It quite challenges the teachers as well as the students to fully support the success of the online classes.Teachers are required to be more creative in delivering the learning materials that will be given to their students. Meanwhile, students are encouraged to be autonomous learners. This paper aims to investigate the students’ perceptions toward the implementation of the ZOOM application to support the online learning process and explore how this application gives a new shape in the educational industry. The qualitative approach was chosen for this study. The data were obtained from questionnaires and interviews. Based on the findings, there are some perceptions about the implementation of ZOOM to support online learning. The result showed that most students thought implementation of e-learning should be improved continuously. Surprisingly, it gave significant changes toward the learning and teaching process, especially during covid-19 itself.

The utilization of renewable energy is slowly starting to become one thing that to be interesting inside the development of science technology. The utilization of renewable energy is from at least two renewable energy (Solar Power Plants and Wind Power Plants), State Electricity Enterprise (PLN), and Generator Sources. This device could be operated automatically and integrated on the internet, which has a monitoring system such as voltage, inside which will be used to control everything inside that system. This device is designed to be operated in a combinational manner. This means to be operated based on the voltage value which qualified to activate the load. The utilization of the 3.3V microcontroller is able to design an efficient and low-cost board. Besides that, the device also uses the PLN and Generator set sources as the power backup when the main power runs out. Base on the research noted, this device will distribute the electric source to the houses, which means beneficial for the local society. This device might be applied automatically to four different sources with C++ Programming language to set the point value.
