Abstract

Welding is an important process in the shipbuilding industry that affects the strength and safety of ship structures. At PT BVS, the Flux Cored Arc Welding (FCAW) process still produces a high defect rate, particularly types of defects such as porosity, slag inclusion, undercut, root concavity, and lack of fusion. Based on data from January to May 2025, the reject rate reached 56%, far exceeding the company's standard of 10%. This study aims to identify the types and causes of defects in FCAW welding, as well as provide improvement proposals using the Failure Mode and Effects Analysis (FMEA) method. The analysis show that the three causes with the highest RPN values come from human factors, methods, and machines. Improvement proposals include operator training, preparation of welding Standard Operating Procedures (SOP), regular equipment condition checks, and adjustment of welding parameters. The implementation of these improvement proposals is expected to reduce the defect rate, improve the quality of welding results, and minimize rework costs and production delays. This study provides practical contributions for companies in enhancing welding quality and serves as a reference for quality control in the shipbuilding industry.

Abstract

Supplier selection plays a pivotal role in the operational efficiency and cost management of manufacturing industries. Appropriate supplier choice directly affects the production costs and overall competitiveness of a company. This study aims to explore the supplier selection process within manufacturing firms through the application of Multi-Criteria Decision Making (MCDM) methods. A systematic literature review was conducted using scientific articles indexed in Scopus, analyzed with the Bibliometrix package in R Language. The findings highlight various MCDM approaches utilized in supplier evaluation and selection, along with the key criteria considered in decision-making processes. This research contributes to a deeper understanding of methodological trends and practical considerations in supplier selection, offering insights for both academic and industrial applications. Keywords: supplier selection, manufacturing, MCDM, literatur review
