Abstract

This research aims to comprehensively analyze the 2005 BP Texas City accident by integrating Fault Tree Analysis (FTA), Layers of Protection Analysis (LOPA), and Aspen HYSYS conceptual simulation. Using a qualitative descriptive approach, this study reconstructs systemic failures based on official investigation reports. FTA results reveal complex interactions between instrumentation failures, operational deviations, and design weaknesses as primary causes, while LOPA evaluation demonstrates the ineffectiveness of all independent protection layers in preventing hazard escalation. Furthermore, Aspen HYSYS simulation visualizes the dynamics of mass and energy imbalance during the start-up phase leading to column overfilling. This research contributes significantly to the development of process safety education by providing an integrated risk analysis framework to understand the evolution of industrial accidents holistically. The practical implications emphasize the urgency of implementing inherently safer designs, improving start-up management, and strengthening safety culture to prevent the recurrence of catastrophic incidents in the future.

Abstract

This study evaluates occupational health risks due to exposure to physical factors in the workshop of PT Wesi Kuning Sukses using a quantitative observational design with a cross- sectional approach. The methodology integrates Similar Exposure Groups (SEG), semi- quantitative Health Risk Assessment (HRA), and ArcGIS® spatial modeling. The measurement procedures are based on national technical standard literature studies, including SNI 8427:2017 (noise), SNI 16-7061-2004 (heat), SNI 7062:2019 (lighting), SNI 7054:2019 (vibration), and SNI 16-7060-2004 (UV radiation). The results show noise (93 dBA) and ultraviolet radiation (0.71 µW/cm²) as high-risk priority threats because they exceed the Threshold Limit Value (TLV). Conversely, the parameters of lighting, heat, and vibration are categorized as medium risk according to Permenaker No. 5 of 2018. Spatial analysis identified critical hazard zones within a radius of 0–9 meters, while areas beyond 15 meters were deemed safe for residential use. Although biological monitoring did not reveal acute complaints, latent risks remain. The integration of SEG, HRA, and ArcGIS® proved effective in developing an accurate industrial hygiene management system for long-term occupational health protection.
