Confirmatory Factor Analysis (CFA) for Permit to Work (PTW) on occupational accident at Petrochemical Complex, Kerteh Terengganu

Abstract

There are a series of Process and Occupational Accidents occurring offshore and onshore facilities. It is disturbing that some of the Chemical Industrial accidents in all maintenance and construction activities despite having Permit to Work (PTW) to control the activities. Using quantitative research methods based on Structural Equation Modeling (SEM), this study to determine the purpose of this study was to examine the Confirmatory Factor Analysis (CFA) for PTW (work description, hazardous activity, work inspection, supporting document, and closeout) on occupational accidents. A total of 260 research samples were included in the study. Data were analyzed using IBM-SPSS-AMOS (SEM) program version 21.0. SEM analysis consists of two main models: the measurement model and structural model. Before the SEM test, some adjustment tests to ensure that the tested indicator represented the measured construct. The findings show that all constructs PTW show the compatibility of the hypothetical models tested is verified using the Fitness Indexes to see the values of Root Mean Square Error of Approximation, Goodness of Fit Index, Comparative Fit Index and Chi-Square/Degree of Freedom. Combined factorization analysis of all measurement models shows that the three categories of model compatibility indexes achieved for all models of constructs and discriminant validity.
