Abstract

Air tank dust collectors are essential for safeguarding air quality and operational safety in industrial environments. Nevertheless, these systems are highly susceptible to hazards arising from abnormal pressure and temperature conditions. This study employs Hazard and Operability Analysis (HAZOP) to systematically identify and evaluate risks associated with air tanks in dust collection equipment. Conducted within an industrial setting, the analysis highlights that excessive pressure and elevated temperatures can result in severe outcomes, including fires, explosions, and mechanical failure. To mitigate these risks, the study recommends the installation of safety valves, integration of advanced pressure and temperature sensors, and implementation of rigorous maintenance schedules. The findings confirm that HAZOP provides a structured framework for detecting potential hazards and developing preventive measures, thereby enhancing reliability and safety in industrial operations. This research contributes to the broader field of industrial risk management by demonstrating the effectiveness of HAZOP in addressing critical safety challenges related to pressure and temperature control.

Abstract

This study assessed the operational feasibility of a horizontal cylindrical pressure vessel used for liquefied petroleum gas (LPG) storage at PT. XYZ in Yogyakarta. The evaluation included data collection, visual inspection, thickness measurement, and the calculation of the Maximum Allowable Working Pressure (MAWP) following the ASME Section VIII Division I-UG-27 standard. Results indicated that the vessel’s actual shell thickness of 14.8 mm exceeded the minimum required thickness of 14.66 mm, and the head thickness of 16.4 mm was above the required 14.57 mm, confirming structural adequacy. The calculated MAWP for the cylindrical shell was 1.78 MPa (18.14 kg/cm²) and 1.99 MPa (20.29 kg/cm²) for the ellipsoidal head—both higher than the design pressure of 1.765 MPa (18 kg/cm²). Additionally, hydrostatic testing at 23.40 Kg/cm² (about 30% above the design pressure) showed no leakage or deformation, validating the vessel’s mechanical integrity. Additionally, the unit complied with Occupational Safety and Health (OHS) dan pressure vessel design regulations, ensuring its safety for continued use. This research underscores the importance of vocational education in technical engineering, particularly in pressure vessel testing and adherence to safety standards. By integrating comprehensive training, professionals are better equipped to ensure the structural integrity and safe operation of pressure vessels in industrial settings. The study provides essential insights into maintaining safety and operational efficiency in pressure vessel applications.

Abstract

This study aims to examine workplace hazards and assess occupational risks associated with dust collector operations in mining environments, while formulating an effective socialization strategy to enhance workers’ understanding of HIRADC implementation. The research method involves identifying potential hazards, evaluating risk levels, and determining appropriate control measures based on real field activities. Findings indicate two primary hazards: the possibility of electrical short circuits during equipment operation and dust exposure during filter cleaning, both categorized as moderate to high risks. The proposed socialization approach includes interactive training sessions, visible hazard information postings at the worksite, and regular evaluations of control effectiveness. In conclusion, continuous HIRADC socialization can improve workers' safety awareness, reduce accident and health risks, and strengthen the overall safety culture within the mining industry. Validation of the research findings was carried out by a certified Occupational Safety and Health (OSH) expert, confirming that the proposed socialization and control strategies align with practical safety standards and effectively support risk reduction in mining operations.
