Abstract

Konsekuensi dari sebuah negara maritim adalah adanya peningkatan kecelakaan laut, Jenis kecelakaan yang terjadi adalah tenggelam (37%), kandas (13%), tubrukan (15%), kebakaran (18%) dan jenis kecelakaan lainnya (17%) Sedangkan penyebab kecelakaan kapal adalah 37% human error, 23% kesalahan teknis, 38% karena kondisi alam dan 2% untuk penyebab lainnya. Hal ini disebabkan karena lemahnya sistem identifikasi terhadap kapal yang melintasi perairan Indonesia. Peneliti sebelumnya melakukan integrasi data Automatic Identification System(AIS) dengan Shipping DatabasedanInformation System (GIS)yang memungkinkan melakukan estimasi pencemaran udara.Pengembangkan sistem prioritas inspeksi kapal berdasarkan tingkat resiko yang dimiliki oleh masing-masing kapal.Serta pengukuran tingkat penggunaan bahan bakar berbasis AIS.  Akan tetapi penelitian sebelumnya belum menjadi sebuah sistem monitoring yang dapat diakses secara real time, dengan demikian penelitian ini melakukan pengembangan sistem monitoring data AISberbasis website secara real time.Dari sistem monitoring ini dapat dilakukan pemantauan dan identifikasi kapal yang melintasi area pelayaran dalam coverage perangkat AIS. Kata Kunci - AIS, WebsiteMonitoring , Real Time.

Abstract

This research is aimed to build ship’s ballast water treatment prototipe that used to inactivate microbial water patogen in ballast water to produce unpolluted ballast water that can be standardised by IMO Ballast Water Management Convention. A simple concept that used in the development of this prototype is by draining ballast water with capacity at 5 lpm, 10 lpm and 20 lpm into alternative filtration crumb rubber and UV reactor. In the filtration process using crumb rubber, ballast water will be filtered with the precision filtration up to 50 micron, while in the UV reactor ballast water will be illuminated by UV-C with maksimum dose 16,58 mW/cm2. Finally,the study shows the performance of alternative filtration of crumb rubber and UV-C irradiation on microbial water phatogen, and at what UV-C dose ballast water treatment prototipe can inactivate  microbial water phatogens, which are complying with IMO Ballast Water Management Convention ANNEX D.This research is aimed to build ship’s ballast water treatment prototipe that used to inactivate microbial water patogen in ballast water to produce unpolluted ballast water that can be standardised by IMO Ballast Water Management Convention.

Abstract

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.

Abstract

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.

Abstract

Maintenance is one of the important things to maintain a company in the industry. A company, such as LNG production company, must be able to produce and meet energy needs independently to support all operations, such as cooling water system that functions to control the temperature and pressure so that the production process runs optimally. If this system is disrupted, there will be excess use of water, waste water, and energy costs needed which result in higher total operational costs. With good and right care, it can reduce all risks posed. One component that plays a role in the cooling water system is a pump. This pump serves to flow the cooling water which is seawater to the LNG industry plant. At present, the amount of Work Order data recorded from the problems obtained from the pump requires maintenance updates. In this study, the method in the maintenance programs are used based on the Reliability-Centered Maintenance (RCM) implementation. RCM will increase cost efficiency, reliability, pump uptime, and propose maintenance tasks. Beside pump, the reviewing also involve supports components that affect pump optimization. In this paper, the functions, causes, and effects are identified and the new scheduled maintenance tasks are shown

Abstract

Shipyard is an industry that have major role on trading, shipyard industry leads another industry to triumph, this has been proved in many countries. Factors that are related to workplace accidents in shipyard workers are disturbed when using safety harness while working at height, less knowledge about static electricity, do not take measurements of indoor gas before work, working more than eight hours, constant growing pressure. Precautions include checking safety equipment used to work at height, routinely checking cables, electrical circuits, and electrical equipment, conduct indoor gas measurements, make the worker's shift schedule to eight hours per day and increasing workers to complete the job by finding new employees, short briefing.
