The Analysis of Factors Affecting Preparation Level for the Industry 4.0 Era in the COVID-19 Pandemic on Employees in DKI Jakarta

Abstract

This study analyses significant factors affecting the level of preparation for the industry 4.0 era related to anxiety about the COVID-19 pandemic on employees in DKI Jakarta. Apart from being influenced by the anxiety of the COVID-19 pandemic, the level of preparation for the industry 4.0 is also differentiated by gender, age, education, marital status, decreasing income, and loyalty. Therefore, companies can arrange the planning related to preparing the industry 4.0 during the COVID-19 pandemic if those factors have been figured out. This study used a quantitative method, and the population of this study is full-time employees in DKI Jakarta. The sample was selected by using the snowball sampling technique distributed to 12 companies in DKI Jakarta. The distribution was conducted through the WhatsApp application for a month, and it was gained 228 respondents. Snowball sampling technique used in correlation with the implementation of large-scale social restrictions caused by COVID-19 pandemic. The data analysis used a multiple linear regression model. The results show that factors affecting the level of employees’ preparation in DKI Jakarta for industry 4.0 related to the anxiety of the COVID-19 pandemic are loyalty and a decrease in income.

Application Preparation of High‐Performance Iron‐Based Powder Metallurgy Sintered Materials in Sports Industry

“…The material composition of the working layer and the nonworking layer of the bimetal valve seat ring is different, and the thermal expansion coefficient is different. Therefore, the radial shrinkage rate k of the two layers of materials needs to be tested before and after copper infiltration [13]. A screw micrometer (accuracy: 0.01 mm) is used to measure Journal of Nanomaterials the size of the sample before and after the copper infiltration and calculated according to formula ( 12), d 1 is the diameter before copper infiltration (mm), and d 2 is the diameter after copper infiltration (mm).…”

“…The strength of ring-shaped powder metallurgy parts is often tested by crushing test. The ring-shaped sample is subjected to radial load until it is crushed to obtain the maximum load F, and the crushing strength is calculated by formula (13). Among them, F is the maximum load (N), D 1 is the outer diameter of the ring (cm), h is the height of the ring (cm), and e is the thickness of the ring (cm).…”
