Abstract
During the internship at the Supply Chain Management (SCM) Division of PT Pertamina Gas, the author was involved in supporting a national strategic project involving the procurement of API 5L Grade X65M carbon steel pipes for the Cikampek-Plumpang gas transmission line. Activities included data entry into the SCMboard system, monitoring procurement methods such as limited tenders, open tenders, direct selection, and direct appointment, as well as analyzing technical documents. One important aspect studied was compliance with acceptance criteria, including outer dimension tolerances, wall thickness, pipe length, and mechanical property testing.
API 5L X65M pipes were selected due to their combination of high tensile strength, competitive pricing, and compatibility with external protective systems such as Fusion Bonded Epoxy coating. Literature reviews and market data from S&P Global Commodity Insights indicate that the Asia-Pacific region has high demand for pipes, while also serving as a source of vendors offering prices and quality in line with international standards. The reliability of the pipes is further validated through Manufacturing Procedure Specification (MPS) and Inspection and Test Plans (ITP) documents, which include comprehensive testing such as hydrostatic pressure testing, tensile testing, impact testing, and full ultrasonic testing.
The Cikampek-Plumpang pipeline project crosses densely populated areas and is susceptible to corrosion, making material selection and inspection systems critical factors in ensuring the safety and efficiency of gas distribution. Through this internship, the author gained an understanding of procurement processes at the headquarters and the technical contributions to the success of national projects. This experience demonstrates that limitations in academic background are not a barrier as long as there is a willingness to learn, adapt, and actively contribute.
