<![CDATA[Solenoid hoses are critical components in the hydraulic and pneumatic systems of bulk cement carriers, as they channel fluid pressure to actuators and valves during the unloading process. On the KM. Tonasa Line XIX, solenoid hoses frequently rupture during unloading, disrupting the smooth flow of operations. This study aims to identify the causes of solenoid hose ruptures and propose preventive measures. The study employed a qualitative descriptive method using a case study approach. Data were collected through observations during sea trials, interviews with the chief officer and crew members, documentation, and a literature review. Data analysis was conducted using the Miles and Huberman interactive model, which includes data reduction, data presentation, and drawing conclusions. The results of the study indicate that solenoid hose failure is caused by a combination of system pressure exceeding safe operational limits due to the non-gradual opening of valves, degradation of hose material that has exceeded its service life, and the suboptimal implementation of preventive maintenance. Additionally, a lack of monitoring of pressure indicators during the loading and unloading process further increases the risk of failure. Recommended preventive measures include routine inspections using checklists, periodic hose replacement based on service life, gradual valve operation, and the installation of pressure relief valves to maintain stable system pressure. Implementing these measures can improve the reliability of the loading and unloading system, reduce the potential for damage, and support vessel safety and operational efficiency.]]>
