Safety culture is widely known to have the ability to encapsulate all factors including perception, psychology, and attitude. This ability serves as an important role for organizations in occupational safety and health. Further, this ability is used as an effort to reduce the risk of accidents. One of the efforts made is to measure the level of maturity of the safety culture in the steel manufacturer production area by involving the variables of safety culture, namely commitment, leadership, responsibility, competence, engagement & involvement, information & communication, risk, and organizational learning. This study aims to measure the level of safety culture maturity in the activities production area of steel manufacturers. Data collection was carried out by distributing questionnaires with a purposive sample of 107 workers. Two expert judgments are involved as determinants of the safety culture variable weights using the AHP (Analytical Hierarchy Process) method. The results showed that the level of safety culture maturity in the production area of steel manufacturer was 3, 64, which falls in the proactive category. The priority for improvement of safety culture variables starts from the leadership to the information & communication.

Success in ensuring agricultural production through fertilizer production is the key to strengthening national food security. PT X is a domestic company producing ZA fertilizer. In this study, the endeavor to implement lean manufacturing with a nine wastes (E-DOWNTIME) approach to eliminate waste, so productivity can be increased by relying on a combination of VSM and HOR methods to identify wastes to propose remedies to the risks arising from waste on the ZA production floor, through FGD. This research focuses on risks to waste each production process flow according to the business process adopted. The results showed a waste of waiting, defects, excess processing, and EHS on the ZA production floor. 28 risk events were identified and 28 risk agents were identified. After two alternative repairs were selected namely replacement of the drum filter shaft and replacement of the turbine rotor, the duration of the NVA was 79 minutes reduced. Corrosion, aging, and abrasion machines / tools are the selected risk agents, representing that operating machines have shown a decline in performance due to age, so that a gradual machine update is necessary.
