Analysis of Boiler Operations in the Engine Room Laboratory of Makassar Maritime Polytechnic for Recertification by the Occupational Safety and Health Office of the Department of Manpower

Abstract

This study analyzes the feasibility and operational safety of boilers at the PIP Makassar Engine Hall Laboratory as part of recertification efforts through the integration of technical testing directly supervised by the Ministry of Manpower's Occupational Safety and Health Authority. The novelty of this study lies in its empirical validation through three stages of systematic testing—visual inspection, hydro test, and pressure test—to ensure that maritime education safety standards are met. The test results show that the boiler is structurally recommended for operation because the safety valve functions optimally by opening at a pressure of 5 kg/cm^2. However, through the hydro test procedure up to a pressure of 7 kg/cm^2, critical weaknesses were found in the form of leaks in the manhole packing, two check valves, and two filling pump valves. These findings provide practical contributions in the form of identifying specific points of failure that require immediate repair and chemical maintenance before use in cadet training. This study concludes that although the main unit is seaworthy, the reliability of the support system is a key variable in mitigating the risk of explosion and ensuring work safety in the laboratory.
