This study aims to analyze product failures and propose improvement actions for cabinet products at CV. Arafah Jaya Purwakarta. Based on production data from November 2024 to April 2025, cabinet products showed the highest defect rate compared to other products, reaching 13%. The most common defects include wood cracks, warped wood, and brittle wood. Failure Mode and Effect Analysis (FMEA) was applied to identify and prioritize potential failures based on the Risk Priority Number (RPN), while Fault Tree Analysis (FTA) was used to systematically determine the root causes of failures. The analysis results indicate that the main causes of defects are related to substandard raw material quality, environmental conditions, and insufficient supervision during the production process. Based on the results of FMEA and FTA, improvement proposals were developed using the 5W+1H approach, focusing on improving raw material selection, controlling wood storage conditions, and enhancing work procedures and production supervision. These improvement efforts are expected to reduce defect rates and improve the overall quality of cabinet products.

The construction sector is an industry with a high level of work accident risk due to its dynamic and complex work characteristics. This study aims to examine the application of the Occupational Health and Safety (OHS) System and evaluate its effectiveness in mitigating risks at the Health Facility Building Construction Project (Project X) in Fakfak Regency. The research method used is a descriptive-analytical quantitative approach with purposive sampling of 25 respondents, including executors, supervisors, and field workers. Risk analysis was conducted using the Failure Modes and Effects Analysis (FMEA) method by measuring Severity, Occurrence, and Detection parameters to produce a Risk Priority Number (RPN). The results show that RPN values range from 52.35 to 452.30. The highest risk was found in the variable of limited safety signage in hazardous locations (RPN 452.30), which falls into the very high category. Additionally, 10 high-risk variables and 9 medium-risk variables were identified, dominated by technical, operational, and management factors, such as the use of heavy equipment by uncertified operators and weak implementation of Standard Operating Procedures (SOP) and OHS audits. This study concludes that the application of OHS in Project X is still reactive and requires strengthening risk-based safety management systems as well as improving workforce competence to achieve zero accident conditions.
