Safety is the thing that needs to be preferred by users of transport, passengers should also understand about safety procedures and evacuation procedures in the means of transport. There have been many accidents that happen in the world of transport, particularly in the shipping world, from 2010 to 2016 is no more than 50 accidents of ships in accordance with the cause recorded by KNKT (Komisi Nasional Keselamatan Transportasi). On this research was discussed the evacuation time on the ship KM Zahro express that occurred earlier in the year 2017 in the Kepulauan Seribu, DKI Jakarta. Almost all passenger dead caused by fire from power source in engine room. This thesis will explaine about evacuation time and dangers from fire that interfere the process of evacuation. The methods used are Agent Based Modeling and Simulation (ABMS) and Fire Dynamics Simulator (FDS) for modeling fire simulation. Agent-Based Modeling software (pathfinder) and Fire Dynamics Simulator software (pyrosim) are used to calculate time evacuation in normal condition and fire condition of KM Zahro Express. Agent-Based Modeling and Simulator (ABMS) is a modeling method that aims to model complex problems based on real cases. Agent-Based Modeling and Simulator (ABMS) is designed to model a place that has a seat, path, exit door, humans, and others. Pyrosim is a graphical user interface for the Fire Dynamics Simulator (FDS). FDS models can predict smoke, temperature, carbon monoxide, and other substances during fires. In this case the existing models can be used to plan and prepare an emergency if unwanted things happen. As well as using basic rules which refer to the Safety Of Life At Sea (SOLAS) and International Maritime Organization (IMO). Result of Evacuation simulation calculation on emergency conditions (two rear exit doors will be closed) that match at actually condition is 29,783 minutes (respon is not taken in this simulation), calculation results obtained from simulation of evacuation (Traveling Time) and at the count expanded feet according to the IMO formula (performance standard). From fire simulation could be analyzed the time and the amount of smoke on deck. It can be seen that in the 1800 seconds smoke levels produced in the relatively high place so disturbing in the evacuation process.

Reliability Centered Maintenance (RCM) as one of the processes that used to decisive action which should be performed to ensure any physical components or a system can work optimally in accordance with the function desired by its users. Basically, RCM used a risk management principles of the failure of the components so that it can be determined the type of maintenance properly. With the appropriate type of maintenance, then the failures that may occur can be prevented at once to be able to be detected before they occur. Appropriate implementation of RCM, capable of delivering cost savings, the impact on both the cost of maintenance as well as repair costs due to the occurrence of failure. In this paper, the components become the object of research is the main engine of the KT. X tugboat belongs to Pelindo Marine Service (PMS) Surabaya. KT. X tugboat has the lowest level of availability of the entire company-owned tugboat 80.01 percent. Tugboat is one of the main assets of PMS who support the economy of the company. Therefore, it is imperative for a company to further enhance the efficiency of activities of its operations. These include the efficiency of human resources, as well as economic analysis of system reliability of company assets. It is used in order to keep abreast of competition at the world maritime national and globally. Implementation of RCM process on main engine KT. X, priority levels can be specified against the failure of components that have critical consequences. So it can be a planned maintenance system generated properly and efficiently.

Every ship project would not be apart from risk and uncertainty issues. The inappropriate risk assessment process would have long-term impact, such as financial loss. Thus, risk and uncertainties analysis would be a very important process in financial feasibility determination of the project. This study analyzes the financial feasibility of 17,500 LTDW tanker project. Risk and uncertainty are two differentiated terminologies in this study, where risk focuses on operational risk due to shipbuilding process nonconformity to shipowner finance, while uncertainty focuses on variable costs that affect project cash flows. There are three funding scenarios in this study, where the percentage of funding with own capital and bank loan in scenario 1 is 100% : 0%, scenario 2 is 75% : 25%, and scenario 3 is 50% : 50%. Monte Carlo simulation method was applied to simulate the acceptance criteria, such as net present value (NPV), internal rate of return (IRR), payback period (PP), and profitability index (PI). The results of simulation show that 17,500 LTDW tanker project funding by scenario 1, 2 and 3 are feasible to run, where probability of each acceptance criteria was greater than 50%. Charter rate being the most sensitive uncertainty over project's financial feasibility parameters.

Flooding Causes Analysis in The Engine Room of KM. Nusantara Akbar Trika Pitana; Hari Prastowo; Muhammad Badrus Zaman; Aleix Nurwahyudi; Rachmat Gunawan

The study analyzes about the cause of the leak in KM Nusantara Akbar’s engine room. However, this research is focus on leakage caused by shaft deflectio From the field data provided by the KNKT, know the cause of the leak is packing driven by a shaft deflection and therefore can not hold the rate of water. Analysis was done by a review of the technical and non-technical factors, because the scene of the ship accident was not purely due to technical factors but also non-technical factors. The first step is analyzing the ship document, such as the certificate of ship from classification, incident reports, docking report, ship crew certificates and other ship document. Then on the next step, the evidence that has been obtained from the analysis of the documents related to the ship sail is use to make the analysis using 5 whys method to looking for the root cause. According to the analysis that has been done, the technical cause of the leak vessel caused by system shafting system is reconditioned flange bolts that have been damaged and the addition of flax on the bearing shaft has to cope without straightening axle deflection itself. While the Autodesk Inventor 3D modeling software obtained bolt broken because the act force is 10782.31 N with the shear stress 2.230 MPa, while the maximum force in the normal load is 9.434,531.N with shear force 1,951 Mpa. Then from the cause from non-technical factors are equipment / spare part to overcome the failure of shafting system is very less, the workplace is dirty and uncomfortable and happened miss communication between the crew in the engine room to overcome the leakage.
