The role of internal auditors in meeting the ISO 9001: 2015 quality management standard (Case study: Kilang Pertamina International Refinery Unit V Balikpapan)

The global market is becoming increasingly competitive, and companies need to focus on improving the quality of their products and services to stay ahead. This study aims to evaluate the effectiveness of implementing the ISO 9001:2015 quality management system at PT Kilang Pertamina International Refinery Unit V Balikpapan and compare it against the standards set out in ISO 9001:2015. The audit conducted in September-October 2022 faced some delays due to the slow preparation of work systems, and only 27% of the audit findings were implemented instead of the targeted 100%. This delay had negative implications for both internal and external aspects of the company. The study used qualitative methods to evaluate the results of implementing the quality management system. The results showed that the implementation of ISO 9001:2015 had positive effects on the company. Workers became more aware of quality standards, and managers improved their leadership skills through campaigns related to Quality Health Safety Security and Environment. Additionally, the implementation of the standard encouraged innovation and continuous development of products and businesses. It is recommended that the Internal Auditor Team and Quality Management section hold regular training and socialization sessions to increase worker awareness of the importance of the Work Procedure System and ISO 9001:2015 quality management standards.
