Abstract

PT. XYZ is an international company operating in the energy sector, especially oil and gas, with a focus on fabrication and construction activities for large-scale projects. One of the main production processes that is very influential is welding. To ensure welding quality, PT. XYZ uses the Non-Destructive Testing – Ultrasonic Testing (NDT-UT) method. However, during the inspection process, problems are often found in the form of rejects due to defects that do not meet welding quality standards. Some types of defects detected include LOF (Lack of Fusion), LOP (Lack of Penetration), and ESI (Excessive Spatter Inclusion). This research aims to determine the percentage of the most dominant welding defects, identify factors that cause defects, and provide recommendations for improvements to improve welding quality. The method used is Statistical Quality Control (SQC) with the help of tools such as check sheets, histograms, Pareto diagrams, scatter diagrams, control charts and fishbone diagrams. Based on the data collected, a LOF defect of 5,434 mm was found, an ESI defect of 1,990 mm, and an LOP defect of 1,030 mm. SQC analysis shows that the dominant defect is LOF with a percentage of 64%. The main causal factors come from methods, humans, machines and materials. Therefore, companies need to make improvements and developments to reduce product defects so that they can improve welding quality.

Abstract

This study aims to analyze the strategy of improving employee performance at PT XYZ, a state-owned company that plays a vital role in the provision of electricity in Indonesia. In the context of increasingly fierce competition and increasing customer demands, SWOT analysis is used to identify the strengths, weaknesses, opportunities, and threats facing companies. The results of the analysis show that internal strengths, such as technical expertise, can be leveraged to develop more innovative products and services. This study also emphasizes the importance of improving service quality as a key factor in increasing customer satisfaction. Thus, the recommendations produced are expected to assist PT XYZ in formulating an effective strategy to achieve its business goals. The results of this research make a significant contribution to the development of human resources and the improvement of company performance.
