Conceptual Modeling of Safety Culture in Coal Steam Power Plant Operations and Maintenance Services in Indonesia

Abstract

Abstract The safety culture plays a very important role in shaping the behavior of workers in the operation and maintenance of the Coal Power Plant. Thus efforts to reduce work accidents in operation and maintenance must begin by establishing a good work safety culture. However, the study of the culture of workplace safety and the influence between dimensions of the culture of workplace safety is still very rare in the operation and maintenance of the Coal Fired Power Plant (PLTU). This research is aimed at knowing empirically the influence of the dimensions of safety culture on strategies to improve safety performance. To achieve this goal, first proposed a model consisting of eight dimensions of safety culture namely commitment, leadership, responsibility, competence, engagement & involvement, information & communication, risk, and organizational learning. Confirmatory Factor Analysis (CFA) was conducted to confirm the eight safety culture constructs. This model is then tested by Structural Equation Modeling (SEM) to identify the most significant relationship influence. Data was obtained by distributing questionnaires to 246 workers at PLTU A and PLTU B in Indonesia using stratified sampling and measurement methods using a safety culture maturity model. These findings attempt to help the operation and maintenance services company management by identifying the significant influence of dimensions to improve safety performance.
