Abstract

Mild steel roofing is increasingly being used in simple construction processes. Prima Land Company dominates the lightweight steel roof market share in Pandeglang. However, accidents can come in its manufacturing process, and the potential hazards have yet to be fully measured. Therefore, this study aims to identify, assess, and provide risk control to prevent and reduce work accidents at Prima Land Company. The methods used are Hazard Identification and Risk Assessment (HIRA) and Job Safety Analysis (JSA). HIRA is used to identify the hazard in the mild steel roofing process area, whereas JSA is used to identify hazards in forklifts and lift operations. The results showed that eight activities have potential risks in manufacturing lightweight steel roofs and 16 risks in operating forklift machines and finished loading goods into vehicles. In the HIRA method, the risk category assessment is uniform. However, the highest risk of 38% is extreme risk for sand sprinkling activities, untied and closed plug cables or switches, and transfer of coil raw materials.

Abstract

Wind tower manufacturing demands exceptionally high-quality standards due to its critical role in renewable energy infrastructure. However, defect occurrences during the production process remain a persistent challenge that can compromise structural integrity, increase rework costs, and delay project delivery. This study aims to identify, analyse, and evaluate the risk of defects in the wind tower production process by using an integrated approach of 5 Whys and Failure Mode and Effects Analysis (FMEA). The 5 Whys methodology was employed to trace the root causes of recurring defects, while FMEA was utilized to assess failure modes based on severity, occurrence, and detectability values, resulting in a Risk Priority Number (RPN) for each identified failure. The 5 Whys analysis revealed that the root of the problem lies in the absence of a procedure for verifying work positions before welding. The improvements focused on the design the standard operating procedure, increasing operator competency, controlling process parameters, and validation through trials and inspections to support a decrease in the level of defects and improve product quality.
