Analysis of Digital Learning Practices Impact on Instructor’s Computer Performance at PT PLN (Persero) UPDL Semarang

Abstract

The COVID-19 pandemic has changed the learning system at PLN UPDL Semarang, from in-class to digital training, including the implementation of learning practices. This method has been used officially as one of the learning methods on September 8, 2020. For this method to work well, digital learning practices need to be supported by equipment that meets requirements. In some cases, the instructor experiences problems in the form of a computer hanging or crashing when providing practical guidance sessions so it interferes with learning activities. Therefore, it is necessary to have research to assess the instructor’s computer performance, especially the use of two important components, CPU, and computer memory. The data for this research were obtained from the results of trials in the PLN UPDL Semarang laboratory using an internet connection by simulating the interaction between one instructor and 15 students in stages. This interaction uses Zoom Meeting and Anydesk remote access applications. The result shows that digital learning practices do not have a significant effect on CPU usage but have a significant effect on memory usage. Even the memory usage for a computer with 4 GB RAM can reach 92.5% of its maximum capacity, in contrast to computers with 8 GB RAM which only reach 65% of the maximum capacity. Based on calculations using the linear regression method, it is found that the maximum number of possible clients for computers with 4 GB RAM is 15 students, while 45 students for computers with 8 GB RAM.
