Analisis Masalah Kerusakan pada Pabrik Daur Ulang Beton Hasil Konstruksi PT XYZ

Abstract

This research examines damage experienced by concrete recycling factories of construction concrete residuals. The study integrates three analytical methods: Pareto Charts, Ishikawa Diagrams, and FMEA Tables. Pareto charts are employed to identify dominant types of damage. Ishikawa diagrams pinpoint potential causal factors, including human, machine, method, and environmental elements. The FMEA Table assesses the impact, frequency, and ease of detection level for each causal factor. Data for analysis were gathered through interviews, observations, and document studies. The results of the Pareto analysis reveal four dominant types of damage: damage to recycling screws, cyclone pumps, vibro screens, and WLC sensor components. Potential causal factors for each component are identified in the Ishikawa Diagram. These factors encompass human, machine, method, and environmental elements. Further, the FMEA Table analysis uncovers several factors contributing to a high-risk priority number. These factors include poor component quality, operational errors, overloading, and insufficient maintenance. The analysis results conclude that it is necessary to enhance quality control design by employing more reliable components and integrating sensors for overload detection. Additionally, the study emphasizes the need to improve the current quality control system by incorporating quality checkpoints and ensuring that users are adequately prepared to execute the operation and maintenance processes at the concrete recycling plant.
