ANALISIS PENGENDALIAN KUALITAS PROSES THREADING PIPA DENGAN METODE SPC DAN FMEA PADA PT. ABC
Abstract
PT. ABC is an oil and gas company engaged in the manufacturing of OCTG (Oil Country Tubular Goods) and has been established since 1983 in the Integrated Industrial Area of Kabil, Batam, Indonesia. Its main products are Pipe Casing, Pipe Tubing, Line Pipe, along with Accessories such as Coupling and protector. Despite being certified with ISO 9001:2015 & API Q1, PT. ABC still faces quality challenges, especially in pipe threading. QA 2023 data shows that the defect rate for pipe threading reaches 2.58%, exceeding the maximum target of 1%. Quality control solutions include the use of Statistical Process Control (SPC) and Failure Mode and Effect Analysis (FMEA) to identify root causes, such as lack of operator discipline, material issues, method, and machinery. Actions include periodic training to enhance operator discipline and competency monitoring, as well as increased monitoring of insert replacement and machine maintenance. These measures aim to reduce failure modes and improve product quality.
