Problems that often occur when online learning are, the material delivered by lecturers isn’t optimally taught due to lack of use good learning media. This study aims to find the effective use of online learning platforms in higher education. The research uses a qualitative approach, which aims to analyze, investigate and assess the effectiveness of online learning using e-learning in Indonesia during the Covid-19 pandemic. In addition, this study also compares which e-learning is easy to use, which has full-featured e-learning and which is economical. The subjects in this study were students enrolled in various universities in Indonesia with a total of 136 students. The method of data collection was done by distributing questionnaires via google forms to students. In this study, two analysis were used: descriptive analysis, and qualitative response analysis. The indicators used to see the effectiveness of e-learning are widely used, easy to use, full-featured, and economical. The most widely used e-learning in Indonesia are WhatsApp Group, Google Classroom, Ms. Teams, Schoology, Edmodo, and Moodle. From the results of the analysis it was found that the most effective e-learning used during a pandemic was Moodle. Because Moodle has complete and interesting features compared to other e-learning.

<span lang="EN-US">The selection of learning media in accordance with the subject will greatly affect the interest and response of students in attending learning. In addition, during the COVID-19 pandemic, learning is conducted online, many students are not serious and are not interested in attending learning. Therefore, it is necessary to have media or online lecture platforms that can attract students’ attention, so that students can follow and be interested in learning. The purpose of this study was to look into the impact of Moodle on the research methodology performances of college students in Indonesia. Its goal was to investigate college students’ reactions to Moodle as an innovative online platform. This study included 86 Indonesian college students who sat in a single intact group. Based on the quantitative data, the study used a quasi-experimental design and a one-group pretest-posttest design. A test and a questionnaire were used to collect data. According to the study’s findings, Moodle improved Indonesian students’ research methodology performance. Students were excited to use Moodle because of its simplicity, usefulness, and accessibility. Moodle’s effectiveness in other contexts should be investigated in future research. This study confirmed Moodle's dependability in broader contexts.</span>

This research study focuses on the differences ineffectiveness in the use of media e-learning in the course of research methodology. This type of research is a quasi-experimental research design with a post-test control group design. The populations of this study were all students majoring in electrical engineering education, Faculty of Technic, State University Of Medan, batch 2017 and 2018. Sampling was done by random sampling technique. The research sample of the e-learning Schoology class was 42 students and the e-learning web class was 40 students. From the research data, it was found that there was no difference in learning outcomes between the e-learning Schoology class and the e-learning web. For the effectiveness of using learning media, it was found that web e-learning was considered quite effective compared to e-learning Schoology.

One obstacle to the energy industry’s tendency toward adopting renewable energy is the requirement for a monitoring system for energy transactions based on microgrids in the wheeling scheme (shared use of utility networks). The quantity of transaction expenses for each operational generator is not monitored in any case. In this project, a mobile phone application is developed and maintained to track the total amount of fees paid and received by all wheeling parties and the amount of electricity produced by the microgrid. In the wheeling case system research, the number of transaction costs, such as network rental fees, loss costs, and profit margins, must be pretty calculated for all wheeling participants. The approach created in this study uses a blockchain system to execute transactions, and transactions can only take place if the wheeling actor and the generator have an existing contract. The application of energy trading is the main contribution of this research. The created application may track energy transfers and track how many fees each wheeling actor is required to receive or pay. Using a security system to monitor wheeling transactions will make energy trades transparent.

The Indonesian government has started to fix the problem of industrial change with 'Making Indonesia 4.0' as a strategy to pave the way for Indonesia to become one of the new powers in Asia. One of the steps taken is to change the education system in Vocational High Schools in Indonesia where the education system has turned into competency-based and student-oriented education since April 2018. Teachers must be highly qualified in order to produce students capable of meeting the challenges of the industry revolution 4.0. In this article, we ask the following: "What is the level of teacher readiness in integrating the principles of the industrial revolution 4.0 in the learning process?". Furthermore, this research employs a quantitative technique because data collection this study uses research instruments and its presentation is related to numbers which aim to describe the phenomenon that occurs, including teacher readiness. According to our results, Vocational High School teachers are in the category of ready to integrate the principles of industrial revolution 4.0 in the learning process which is seen from several aspects, follows: (1) Education Competence (EC), (2) Competence for Technological Commercialization (CTC), (3) Competence in Globalization (CG), 4) Competence in Future Strategies (CFS), (5) Counselor Competence (CC). The rapid development of technology can make it easier for vocational teachers to dig up information about industrial revolution 4.0. Therefore that vocational teachers are in the ready category to integrate the principles of the industrial revolution 4.0 in the learning process.
