Depok, December 5, 2025 – The oil and gas industry is widely recognized as a sector characterized by high cost, high risk, and high technology. These characteristics place risk management and safety as critical issues. As a world-class energy company, PT Pertamina (Persero) has set a performance target of Zero Incidents and is committed to embedding a Safety Culture at the highest level, namely the Generative Level, where safety becomes a deeply rooted value in every aspect of the organization and individual behavior.
This raises the question of how such a high level of safety culture can be achieved in a systematic and measurable manner. Through a dissertation research conducted by Indra Pehulisa Sembiring, the most optimal formulation was revealed, namely through the integration of a safety management system known as SUPREME. The research was defended under the title “Development of an Integrated Safety Culture Model with SUPREME at Pertamina” in the Doctoral Promotion Examination of Public Health Sciences on December 5, 2025, at the Doctoral Promotion Room, Building G, FPH UI.
SUPREME (Sustainability Pertamina Expectations for HSSE Management Excellence) is Pertamina’s HSSE (Health, Safety, Security, and Environment) management system. It is specifically designed to meet the operational needs of Pertamina and consists of 8 Processes, 45 Sub-Processes, and 190 Expectations that integrate elements of engineering, safety management systems, and behavior. The research conducted by the doctoral candidate aimed to develop an integration model that ensures the implementation of SUPREME not only impacts HSSE performance but also contributes to the formation of a strong Safety Culture within Pertamina. Changes in safety culture were measured through the achievement of the Safety Culture Maturity Level.
Through quantitative analysis of SUPREME audit data and safety culture surveys, the study demonstrated that the implementation of all SUPREME processes simultaneously has a significant influence on Safety Culture values. This indicates that comprehensive implementation of SUPREME can explain a large proportion of the variation in the formation of organizational safety culture. Nevertheless, while all processes are important, regression analysis revealed that only two processes have a statistically significant impact on Safety Culture values, namely Process 2 (Policy and Objectives) and Process 5 (Planning and Procedures). This finding emphasizes that to build a strong safety culture, organizations must ensure that safety policies and objectives are clearly defined and supported by detailed and measurable planning and work procedures.
“Congratulations to Dr. Indra on earning his doctoral degree at FPH UI. The responsibility to uphold the dignity of this degree must always be maintained by adhering to the values and norms that have been cultivated throughout the course of study at this faculty and the university. May the developed model provide broad benefits to society,” stated Prof. Dr. dr. Zulkifli Djuniadi, M.App.Sc., in his remarks as Promoter.
At the conclusion of the examination, the Chair of the Session announced the decision that Indra Pehulisa Sembiring was declared to have passed and successfully obtained the Doctoral degree in Public Health, as the 28th graduate of the 2025 PhD in Public Health program, the 367th graduate of the PhD in Public Health program overall, and the 482nd doctoral graduate of FPH UI.
