Relationship and Predictors of Effectiveness to Safety Culture in Manufacturing Industrial System.

Abstract

          The objectives of this research were to study the safety culture elements in the manufacturing industry and to analyze the relationship and predictors of effectiveness to safety culture in manufacturing industrial system by utilizing a cross-sectional analytical study method. The research sample group was entrepreneurs and officers related to safety in manufacturing industry that were selected by simple random sampling method which determined the sample group of 385 people. Frequency, percentage statistics, and multiple linear regression were used for the data analysis.

            The results of the study of safety culture elements in the manufacturing industrial system indicated that there were 6 main elements, namely, imports, work processes, results, work environment, ergonomics, experience. In the part of study result of the factors affecting to safety culture in manufacturing industrial system, independent variables were defined as demographic data, import factors, work process factors, outcome factors, work environment factors, ergonomics factors, experience factors. When performing a multiple linear regression analysis of factors affecting safety culture, the factor prediction equation was  = 3.867 +0.211X₁+ 0.203X₂+ 0.096X₄ which was able to predict factors affecting safety culture by 8.8%. The equation found that import factors (X₁), work process factors (X₂) and work environment factors (X₄) had a statistically significant effect on safety culture at the p-value = 0.05 level. From the results of the study when conducting activities to promote safety culture, predictive and influencing factors should be considered first, but other factors should not be ignored.
