<![CDATA[Setiap KRI yang keluar atau masuk alur pelayaran/selat sempit wajib melaksanakan peran pemanduan termasuk KRI Kelas Vanspeijk yang merupakan unsur striking force yang terbesar dan terlengkap baik personel maupun persenjataannya. Keberhasilan peran pemanduan sangat tergantung dari tim anjungan selaku operator tim pengendalian kapal dalam menghindari kecelakaan di laut. Banyaknya kecelakaan dilaut yang terjadi disebabkan oleh kesalahan operator anjungan. Human error yang terjadi dapat dihitung menggunakan metode Human Error Reliability Assessment (HRA) untuk mengetahui tingkat keandalan operator. Terdapat banyak kuantifikasi metode HRA, salah satunya adalah metode SPAR-H(Standardized Plant Analysis Risk Human Reliability Assessment) yaitu sebuah metode yang mengamati 8 (delapan) PSFs (Performance Shaping Factors) dan dependence condition factors setiap operator yang diteliti. Perhitungan nilai Human Error Probability (HEP) akan sangat berpengaruh terhadap dependence factors tersebut. Hasil perhitungan Probability without dependence (Pw/od) akan berbeda jauh dengan perhitungan Probability with dependence (Pw/d) karena dependence factors menjadi lebih dominan ketika kegiatan tersebut dilakukan oleh sebuah timbukan perseorangan. Sejumlah 9 (sembilan) operator dari 6 (enam) KRI yang diteliti terdapat nilai Pw/od terbesar yaitu 0.5025 dan Pw/d terbesar 0.7513 adalah operator Kadiv Nav KRI AHP. Rekomendasi yang diberikan untuk mereduksi human error sehingga tercapai zero accident adalah melatih operator minimal 6 (enam) bulan dan melaksanakan dinamika role game, fit and proper test dan uji kompetensi calon operator baru, pemenuhan operator sesuai SKP (standar kualifikasi personel) serta memberikan suasana anjungan yang lebih kondusif saat peran pemanduan.]]>

<![CDATA[Dislambair Koarmatim adalah satuan khusus penyelaman TNI AL yang mempunyai tugas pokok menyelenggarakan penyelaman dan penyelamatan bawah permukaan air. Penyelaman di dislambair Koaarmatim terdiri dari penyelaman kapal/KRI (Ship Diver), pengapungan dan penyelamatan dalam (Salvage and Deep Sea Diver), Under Water Demolition Divers, dan Quick Response Diving Team. Pada penyelaman kapal/KRI terdiri dari 3 aktifitas pekerjaan penyelaman yang utama yaitu Predive/sebelum penyelaman, Water Entry/Descent/pelaksanaan penyelaman, dan Postdive/setelah penyelaman.Penelitian ini dilakukan dengan menggunakan metode HIRARC. HIRARC adalah suatu metode identifikasi bahaya , penilaian risiko, dan tindakan pengendalian risiko yang biasanya digunakan karena metode ini dianggap lebih tepat dan lebih teliti dimana bahaya yang timbul dijelaskan dari setiap aktifitas kerja. Pada metode ini juga memberikan tindakan pengendalian yang sesuai untuk tiap bahaya. Pengendalian perlu dilakukan untuk mencegah timbulnya kecelakaan dan Penyakit Akibat Kerja (PAK) yang dapat merugikan satuan.Berdasar hasil analisa HIRARC ini, pada setiap aktifitas kerja penyelaman yang dilakukan yaitu pada saat sebelum penyelaman (Predive) dan setelah penyelaman(Postdive) menunjukkan pekerjaan penyelaman yang berisiko sedang (Medium Risk). Sedangkan setiap aktifitas kerja penyelaman yang dilakukan pada saat pelaksanaan penyelaman (Water Entry/Descent), mempunyai risiko tinggi (High Risk). Kemudian rekomendasi yang dihasilkan untuk meminimalkan kecelakaan kerja penyelaman pada saat Water Entry/Descent (pelaksanaan penyelaman) dengan cara elimination, Engineering Control, Administration Control dan Use of PPE (Personal Protective Equipment).]]>

<![CDATA[ABSTRACT The main task of the Indonesia Navy is to enforce the law and maintain security in the territorial sea of national jurisdiction, so that the Indonesian Navy is required to have the main tool of weapons systems (Alutsista) are always ready to carry out the task. The frequent occurrence of accidents experienced by the Indonesian Warship (KRI). This reduces the ability of Warship in performing the task. The purpose of this research is to investigate the causes and effects of accidents, and seek risk mitigation that is considered appropriate. Formal Safety Assessment (FSA) is a structured and systematic methodology used for maritime safety analysis. The fault tree analysis is used to investigate the cause of marine accidents and the event tree analysis is used to determine the impact of an accident. The results of this study are FSA can be effectively applied in accident investigations, although the calculation of cost benefit analysis for warships can be ignored because the Warship task cannot be compared to the value of money. Keywords: Task Operation, Warship, FSA, fault tree analysis, event tree analysis]]>

<![CDATA[ABSTRACT This paper is about designing motion control system with 2-DOF motion equation to be applied to an Autonomous Underwater Vehicle (AUV) system. The 2-DOF motion equation which consists of surge and roll motion in the form of equations of nonlinear motion. The control system design applied to the ITSUNUSA AUV system uses the Proportional Integral Derivative (PID) method. The simulation results of the PID control system with the motion equation with 2-DOF on the ITSUNUSA AUV system show that the system proves to be stable at a predetermined set-point with an error of 0.01% for surge motion and that with an error of 4.2% for roll motion. Keywords: AUV, motion control, PID]]>

<![CDATA[As an archipelago which has a wider sea area than land, Indonesia, in this case the oil company, must be able to serve and accommodate oil throughout the Indonesian sea, especially the eastern region. The lack of tanker cause the run out of fuel oil in remote areas, so there needs to be a sector division included in oil companies. The method used by researchers was the Analytic Network Process (ANP) approach and the set covering problem method. By determining the right dock location for the Tanker, the dock would be able to cover the entire existing sector, and through the determination of the proper tanker assignment plan, the entire territory of Eastern Indonesia would be able to be covered by the presence of the Tanker. The results of the study show that the candidate starting point assignment was produced by 4 (four) ports as the starting point for the assignment of tankers. These ports consist of Ambon in charge of covering sectors 4, 5, 6 and 7, Makasar port was in charge of sector 1 and to cover sector 3 while Tegal port is in charge of covering the patrol sector 2]]>

<![CDATA[Product defects are a natural thing in a production process, but it would be better to avoid them. XYZ Industries is a company that produces glassware in the form of the glass bowl. The production failure experienced by this company is still high at 3.1% of the total production while the defect target that the company wants is 2%. The purpose of this study was to identify the types of defects that occur in glass bowl products on the production floor based on the results of searches of literature studies and deep interviews with employees, get the risk of failure of the largest production process in the RPN (Risk Priority Number) value of the FMEA method then analyzed again using the FTA method and determine the proposed improvements needed based on the analysis of defects that occur in glass bowl products, thus minimizing product defects and increasing company profits. In this study using the method of Failure Mode and Effect Analysis (FMEA) and the Fault Tree Analysis (FTA) method to identify failures that occur and provide prevention solutions. Based on the results of data processing, the proposed improvements given to the company as a whole are the company in order to pay more attention to the maintenance of the machine so that the machine can avoid the failure of its function]]>

<![CDATA[The Indonesian Navy as a defense and security force of the sea has combat tools and supporting facilities projected in the Integrated Fleet Weapon System (Sistem Senjata Armada Terpadu/SSAT) with several components including Indonesian navy ships, marines, aircraft and bases. Depo level maintenance is comprehensive maintenance that can only be carried out by personnel who are experts in their field and supported by complete and sophisticated equipment and facilities. Maintenance at this level includes complete overhaul repairment, repowering MLM (mid life modernization), calibration of all equipment, and repairs to all parts thoroughly. Depo Level Maintenance is the nature of maintaining technical conditions based on rotary hours. If the repair schedule specified in the SPT (System for Planned Maintenance), the schedule must be carried out. This research aimed to present a priority setting solution in Depo level maintenance wherein the highest Indonesian Navy Ship ranking is determined from the level of the decision makers. Fuzzy MCDM is a method developed for decision making on several alternative decisions to get an accurate and optimal decision. In Indonesian Navy Ship Hardepo priority ranking process taken from the level of data processing decision makers using the Fuzzy MCDM method, the 5 highest priority values in implementation were obtained. Hardepo with the highest scores were KRP-812 0.111, BDU-841 0.108, LAM-374 0.107, KRS-624 0.097 and TJA-541 0.073]]>

<![CDATA[Most warships, especially corvette types, have a service life of more than twenty years. Intuitively it can be concluded that the components and equipment that have been installed are in the period of wear from the bathtub curve. This paper presents an alternative method in determining the optimum component maintenance intervals for weapons system equipment on ships that have entered wear (wear out). Optimum maintenance costs are determined by optimizing the component maintenance interval with objective functions to minimize the total cost of increasing reliability. The reliability of the system is achieved by increasing the reliability index of its constituent components. Weibull ++ is used to obtain parameters that are appropriate for each damage distribution, while Excel Solvers are used to calculating optimal maintenance intervals. In this writing, a case study will be carried out on the components of Bofors cannon laying gear TAK 120MM / 46A]]>
