Abstract

This study aims to describe the obstacles experienced by students during limited face-to-face learning. By making class VII-8 at Junior High School 27 Medan as a research sample, it will analyze what obstacles are experienced by students. Research method used is descriptive quantitative method. The study used an instrument in the form of a questionnaire that would be given to students directly and provided four answer choices based on a Likert scale and structured interviews. The results of the study, it was found that students experienced problems in implementing limited face-to-face learning in the four aspects, namely in the aspects of facilities and infrastructure to support learning was obtained in the fairly good category, the classroom management aspect obtained the good category, the aspect of student activity get the unfavorable category, the aspect of student understanding gets the poor category, and the aspect of student concentration in doing learning gets a poor category. For this reason, good management is still needed in overcoming several obstacles in the limited face-to-face learning process, all parties, both principals, teachers, students and other school residents must participate in overcoming the obstacles that arise.

Abstract

In addition to solar, wind, and water waves, there are other sources of energy that are renewable. Researchers are currently testing the use of these energies with a device that can draw electricity from the air. The new energy is electricity in the air that triggers the formation of lightning & lightning. The need for electrical energy is increasing day by day. Electrical energy supply in Indonesia itself is usually supplied from power plants such as Hydroelectric Power (PLTA), Air (PLTU), Solar (PLTS), Diesel (PLTD), and Geothermal (PLTG) whose existence still does not meet electricity needs. The type of research used is descriptive qualitative research by literature study use 10 journals. The purpose of this work is to utilize lightning as an energy source in order to maximize the potential of Indonesia's natural resources, especially in the city of Medan. The results show that lightning can be used as an alternative energy source, because lightning is a renewable energy and will not run out even if it is used continuously.
