Abstract

The objectives of this study are to: 1) identify the knowledge sharing practices of educational staff at Universitas Negeri Medan, 2) assess the performance of educational staff at Universitas Negeri Medan, and 3) explain the influence of knowledge sharing on the performance of educational staff at Universitas Negeri Medan. This research is classified as explanatory research, which examines the relationship between the knowledge sharing variable (X) and the performance variable (Y) of educational staff at Universitas Negeri Medan. The results indicate that knowledge sharing has a positive relationship with performance, as represented by the regression equation Y=15.372+0.2X. The correlation coefficient r=0.49 signifies a moderate relationship between the two variables, with a coefficient of determination of 24.1%, suggesting that knowledge sharing accounts for 24.1% of the variance in performance.

Abstract

Computers have helped humans work better and help in solving problems. Computers continued to evolve and innovation continued, starting with the first very large computers and evolving into the modern, commonly used desktops. When there is a problem with the computer device, such as damage to the computer components. Most people immediately take it to a computer repair service technician. An expert system is a component of artificial intelligence. In order for computers to solve issues in the same way that professionals do, expert systems attempt to incorporate human knowledge into computers. A single technique inside the expert system is the Dempster Shafer technique. The Dempster-Shafer technique is a mathematically based approach that incorporates uncertainty and features traits of expert thought. The research was carried out by detecting computer damage based on the sound that comes out when the BIOS performs a POST (Power On Self-Test) using the Dempster-Shafer method. Users can determine the kind of damage their machine has sustained without having to visit a computer repair service provider directly by using the Dempster Shafer approach.
