A Study On A Model To Improve The Competency Of The Operator Who Operates Water Boiler Or Boilers That Use Liquid As A Heat Carrier Under The Supervision Of The Ministry Of Industry

Abstract

This study aimed to analyze the confirmatory factors of a study on a model to improve the competency of the operator who operates water boiler or boilers that use liquid as a heat carrier under the supervision of the Ministry of Industry. The sample group used in the quantitative research was 495 participants who attended the lecture in the course for the operator who operates water boiler or boilers that use liquid as a heat carrier under the supervision of the Ministry of Industry for the fiscal year 2019 to 2022 of the training center of Institute of Technology Development for Industry. The research instrument was a 5-level rating scale questionnaire based on the Likert method and relative model fit index by confirmatory factor analysis.

Research results revealed that that the participants who attended the lecture had an intention to develop the competency of the operator who operates water boiler or boilers that use liquid as a heat carrier under the supervision of the Ministry of Industry, as a whole, in a high level. Results of the confirmatory factor analysis showed that the structural equation model for the a study on a model to improve the competency of the operator who operates water boiler or boilers that use liquid as a heat carrier under the supervision of the Ministry of Industry was consistent with the empirical data (c² = 176.332, df = 149, p = 0.063, c²/df = 1.183, GFI = 0.964, RMSEA = 0.019)
