Abstract

This article discusses the effect of a cracked clutch shaft on the performance of the gear pump type cargo pump at SPOB Sea World One. Damage was found to the clutch shaft which was indicated by a decrease in the pump flow rate on the ship during bunker service. The aim of this research is to determine the factors that cause clutch shaft cracks, as well as determine the impact of these cracks, and the handling efforts carried out on the clutch shaft. The method used in this research is a qualitative method which produces descriptive data in the form of written explanations. Data collection takes the form of an approach to the research object through direct observation and interviews as well as taking data from the ship. Based on the observations, it was concluded that the impact of the shaft cracking caused noise due to a gap and a drop in pump pressure. And it was found that the factor causing the shaft crack was the lack of implementation of a planned maintenance system on board the ship for the cargo pump, causing the pump to experience over running hours. Turning was carried out as an effort to handle the clutch shaft with an original diameter of 12 cm.

Abstract

Single Buoy Mooring (SBM) is a means for mooring tankers to carry out loading or unloading operations through SBM located on the high seas. SBM serves to facilitate loading or unloading crude oil by connecting the installation on land through pipes connected to the SBM system on the high seas. The thing that is considered so that the mooring process runs safely is by minimizing the factors and hazards that cause the mooring process to be hampered. the danger at the time of loading at SBM is during the process of mooring the ship and the danger of H2S gas contained in curde oil. During the loading of crude oil, the cargo must always be checked for H2S gas levels in crude oil, this gas is quite dangerous when exposed directly to H2S gas. It can cause loss of smell, eye irritation, shortness of breath, unconsciousness and death. This thesis research method is a qualitative descriptive method by analyzing the problem using Hazard Identification, Risk Assessment, Risk Control (HIRARC).

Abstract

This research aims to find out and understand the implementation of the mooring system, ship safety and crew safety, and how the ship crew prepares for the docking process at the jetty. Some of the consequences that arise if the mooring system management plan is not implemented are that it can result in safety threats, both the safety of the ship and the safety of the crew themselves. Among them are ropes breaking when the ship is at the jetty, damage that occurs on board the ship and even injuries to the crew can also result in death, as was the case with the MV Mutiara Persada 2 ship which was docked at the Merak pier at that time. The role of the ship's crew is in implementing a periodic maintenance system for all ropes on board the ship when necessary in accordance with the ship maintenance Safety Management System. Mooring arrangements on ships must be strictly implemented, especially for tanker types, and should refer to the Mooring Equipment Guideline issued by OCIMF (Oil Companies International Marine Forum). Likewise, the lay out of the rope when the ship is berthed at the jetty must also be adjusted to the DWT (Dead Weight Tonnage) of the ship itself to avoid the rope breaking due to supporting the weight of the ship which is not in accordance with the weight of the ship. The writing method in this research is literature study and documentation, as well as descriptive data in the form of writing from several sources. The results of the discussion can be concluded that good rope maintenance management can minimize the impact of rope breaking when the ship is docked at the dock, as well as the implementation of a good mooring system management plan can also avoid the negative impacts that arise or the ship's rope breaking when the ship is docked at the jetty. By adjusting the appropriate rope layout and mooring arrangement in accordance with the regulations determined by OCIMF. So the safety of the ship and crew is very important when sailing or when the ship is at the jetty when loading and unloading

Abstract

This article discusses the importance of carrying out scavenging inspections on main engines on MV. Melchior Schulte, during the M/E scavenging inspection, a problem was discovered in cylinder number 3, namely a broken piston ring which was caused by a lack of cylinder oil lubrication in the cylinder liner. The aim of this research is to find out the correct procedures for carrying out main engine scavenging inspections and to find out the usefulness of carrying out main engine scavenging inspections. This research uses a descriptive method, by describing, describing systematically and accurately the nature, facts and relationships between the phenomena being studied, and tends to focus attention on solutions and solutions to actual problems as they existed at the time the research was carried out. The research results showed that the procedure and time for carrying out M/E scavenging inspection must follow or comply with the provisions in the M/E manual book, with the maximum running hours on the main engine being 500 hours, and the factors that influence the implementation of M/E scavenging were obtained. inspection, namely the main engine experienced a breakdown maintenance moment due to a clogged hole occurring in the injector in cylinder number 3 and a broken piston ring cermet number 4 in cylinder number 3 on the main engine

Abstract

Politeknik Maritim Negeri Indonesia has a model of a tool for moving materials which is controlled using a PLC, but this model is no longer operational and some of its components are broken. The tool is used as a learning media for students majoring in engineering in the field of control systems and PLCs. Tool repairs and modifications are made by adding metal and non-metal material sorters. The problems that arise are how to form a series of ladder diagrams to work in one cycle and the vacuum pressure of air to lift metal and non-metal materials. The method in this study uses research and development (Research and Development). The equipment and materials in this study used the PLC Omron CP1E 20 I/0 and the sample materials were aluminium and nylon with a diameter of 30 and a thickness of 8 mm. The conclusion is that this tool can work using the ladder diagram that has been made in one cycle and the best pressure is 4 bar.

Abstract

This research began with fluctuations in ship visits as a result of employee performance. The performance generated by employees appears to be suboptimal due to factors such as high workload resulting from an inadequate number of employees compared to the volume of ship visits handled by the company, compounded by insufficient facilities such as company transportation. This study aims to determine the influence of workload and workplace facilities on agency performance. The method employed in this research is quantitative, utilizing data collection through questionnaires distributed to 32 employees as respondents at PT. IDT TRANS AGENCY, Sungai Danau Branch. Data analysis was conducted using SPSS (Statistical Package for The Social Sciences) version 24. The results of this research indicate that there is an influence of workload and workplace facilities on performance with an adjusted R square value of 0.784. This means that workload and workplace facilities contribute to 78,4% of the performance, while the remaining part as many as 21,6% is influenced by other factors which is not tested in this study.
