Published: October 2023

The study involved a numerical analysis of the water dropping process by fixed-wing aircraft. This method, also known as air attack, is used for aerial firefighting, primarily in green areas such as forests and meadows. The conducted calculations allowed for the analysis of the process over time. The calculations were performed based on a SolidWorks model of the M18B Dromader aircraft. After defining the computational domain and setting the boundary conditions, the simulations were carried out using the ANSYS Fluent software. The resulting water dropping area was used to analyze the intensity of water distribution. The volumetric distribution and airflow velocity distribution were analyzed for specified time steps. The boundary layer where air no longer mixes with water during the final phase of water dropping was also determined. The obtained results provide an important contribution to further analyses aimed at optimizing the water dropping process by fixed-wing aircraft.

The implementation of the ship maintenance management system on Rear Admiral Jhon Lie's training ship did not run optimally, which impacted the less-than-optimal condition of various training ship equipment because the crew did not carry out the ship maintenance system according to the procedure, resulting in the incident that the ship's anchor winch operation did not function optimally when the ship was anchored in Belang Port, Southeast Minahasa. This study aims to identify and analyze the positive and significant effect of the planned maintenance system on shipping safety. The primary data collection methods used in this study were questionnaires and interviews. In this study, data processing and presentation were in the form of diagrams and path analysis with structural equation modeling (SEM-PLS) using SmartPLS. From the results of the data analysis, the R-square value of shipping safety (Y) is 0.307, which means that the planned maintenance system (X1) and ship maintenance (X2) can affect shipping safety (Y) by 30.7%. Ship maintenance (X2) has a significant effect on sailing safety (Y), with P-values = 0.033  0.05 (hypothesis accepted). The planned maintenance system (X1) has a significant effect on sailing safety (Y), with a P-value of 0.037  0.05 (hypothesis accepted). As a result of the analysis, it was found that the planned maintenance system has a significant effect on shipping safety.
