The Effect of Digitalization for Employees in Manufacturing Companies in the Era of Industrial Revolution 4.0 Using the CFA (Confirmatory Factor Analysis) Calculation Method

Industrial digitalization 4.0 is a change in communication, function and interaction in industry to digital. So, this is an industrial transformation from a conventional concept to a virtual one. The purpose of this research is to examine the benefits of digitalization for employees in various manufacturing companies. This aim provides quite effective benefits in optimizing many things so that we don't need to spend a lot of time and effort to achieve the targets of our work. This research uses the Validity Test and Reliability Test method with a purposive sampling approach technique of 75 respondents from various employees in manufacturing companies. In this study, researchers used the JASP program version 0.17 with CFA (Confirmatory Factor Analysis) calculations. Of the 40 items that describe 3 components including the company's digitalization system, work productivity, job satisfaction. In the trial of the measuring instrument, it was reliable because the results were above 0.07, but the quality of the items was not good because there were still items whose benchmark was below 0.05. This measuring instrument was tested on 75 respondents. Based on the measuring instrument test, in the first stage 14 items were obtained that could be used and 26 items that could not be used with a validity value of 0 out of the 40 items that had been tested.
