Abstract

Corrosion is a significant issue in steel constructions, and zinc coating (electroplating) is one of the methods used to protect steel from corrosion. This research aims to analyze the effect of voltage and duration of zinc coating on low carbon steel A36 through the electroplating process on the corrosion rate and coating thickness. An experimental method was employed, varying the voltage (6, 8, and 10 Volts) and coating duration (10, 20, and 30 minutes) during the electroplating process using a ZnO solution. The corrosion rate was tested electrochemically in a 3.5% NaCl solution. The results showed a significant correlation between voltage, coating duration, corrosion rate, and coating thickness. Higher voltages and longer durations produced thicker zinc coatings and reduced the corrosion rate. The optimal conditions were found at 10 Volts for 30 minutes, producing a 160 (Mu)m thick coating and the lowest corrosion rate of 0.00318 mmpy. The minimal coating condition, 6 Volts for 10 minutes, resulted in a 30 (Mu)m thick coating and a corrosion rate of 0.050120 mmpy.

Abstract

The advancement of ship production technology in Indonesia involves the implementation of modern techniques integrating computer-based design and production facilities, such as Computer-Aided Manufacturing (CAM) for operating production machines utilizing Computer Numerical Control (CNC). One specific type of CNC machine utilized in ship production is the plasma cutting CNC machine. Despite being crucial to production, these machines frequently encounter failures that impede the production process. Through prior failure analyses conducted by the company, it has been identified that the dust collector air hose component exhibits the highest failure rate with six distinct failure modes. This article conducts qualitative and quantitative analyses of the causes of failure in the air hose dust collector of CNC plasma cutting machines using the Fault Tree Analysis (FTA) method. FTA is employed as a method to ascertain the fundamental causes of the event. The analysis results are utilized to provide recommendations for controlling objectives related to occupational safety. Six failure trees are generated, comprising a total of 28 basic causes. The most frequently occurring types of basic causes are associated with workers, methods, and materials. The probability of occurrence for the minimal cut set of each failure tree has been successfully computed. These calculations reveal that all top events possess probability values exceeding 76%. Specifically, the event of the dust collector air gap breaking has the highest probability value, reaching 99.88%, which is a composite of 15 basic causes. Control recommendations are provided in the form of substitution, engineering solutions, and administrative controls.

Abstract

High stability is imperative, safeguarding against the unpredictable nature of the marine environment and promoting a secure working platform for crew members to do fishing operation. The aim of this study is to analyze the effect of laying solar panels on the deckhouse of small fishing vessels 20 GT. The additional load above which causes weight gain and will affect the ship's center of gravity is became the first effect of Fishing vessel stability. The second effect is on how the fishing vessel performs when there is a solar panel on the vessel. The data were collected by measuring the stability according to A.N Kyrylo’s method with standard checks according to the IMO (International Marine Organization). Code on Intact stability calculated the ship motion by using the STRIP method and using the JONSWAP method to measuring the wave characteristics with the help of Maxsurf software. The results of this research show that the installment of solar panels above the deckhouse does not really affect the stability, where the results were meets the IMO standard criteria. The successful fishing operation of the vessels studied will only have a good performance at 1.5 meters, according to the seakeeping analysis.

Abstract

Small pelagic purse seine vessels in Jakarta are dominated by vessels with a length of 14.5 m. The vessel's hull construction was made by a traditional vesselyard using wood. The construction process only relies on the skills and habits of craftsmen. The choice of engine is only based on the size of the vessel and the price of the engine without calculating resistance. In general, the power of the purse seine main engine as the main mover is not suitable, causing wasteful fuel consumption. The fishing vessel engine used by MV Putra Abadi comes from a modified truck engine so that the fuel used does not comply with specifications. This research aims to determine the amount of power needed to move a Putra Abadi fishing vessel. The method used is direct observation by taking direct measurements of the dimensions of MV Putra Abadi. Next, the engine resistance and power are also calculated using the Holtrop resistance method in software. The Putra Abadi fishing vessel based on hydrostatic calculations showed that the block coefficient (Cb) is 0.425 at a speed of 7 knots, the resulting resistance is 2.5 kN. While at a maximum speed of 8 knots the BHP is 98.82. The power requirement of Putra Abadi fishing vessel according to this calculation is only 46% of the engine power currently used.

Abstract

Natural energy is something that can be utilized as an alternative energy besides fossil fuel energy. Considering that the need for fossil fuel energy is decreasing, the purpose of this research is to propose a utilization of natural energy in the form of wind. The implication of the use of this alternative energy in the hybrid power function is that the integration of vertical axis wind turbines and Flettner rotors is chosen as the main driving energy of the model ship that fully utilizes wind energy. The performance evaluation stages in this experiment include design and simulation for the turbine-Flettner rotor, and trials on a model ship using a monohull type hull. The objective of this research is to obtain the optimum performance of the combined vertical-axis wind turbine-Fletner rotor in supporting hybrid propulsion power on a model ship. The power required by Flettner is 0.695 Watt and the turbine rotate at a minimum angular velocity of 40 rpm. The highest contribution of the Flettner rotor at ship service speed 1 knot and ship total resistance of 0.01 kN reached 26,20%.

Abstract

The Federal Government of Nigeria recently announced the plan for new airports across the country in order to ease the air transportation system across the country and its connectedness to other parts of the world. However, the adequacies of the declared sites were not empirically supported through a carefully designed suitability assessment; that assured their appropriateness environmentally and geospatially. Thus, this paper examines the geospatial suitability evaluation of the proposed Airport in the Eti-Osa Local Government Area in Lagos State. A multi-criteria suitability analysis (MCSA) concept in a geospatial environment was adopted, using the analytic network process (ANP)del based on reviewed criteria for the airports' site suitability selection. Different thematic layers of the land cover for the assessment were achieved through the geospatial capabilities of Geographic Information System and Remote Sensing, with the various factors’ priorities from the ANP model in the final analysis of alternative suitability sites for this proposed airport. The final suitability model revealed different levels of this suitability for consideration by relevant decision-makers for better-informed decisions about the project.

Abstract

Indonesia is a maritime country with vast marine areas. Furthermore, Indonesia is also a country with the second-largest biodiversity in the world. Many endemic flora and fauna in Indonesia, some even endangered, are vulnerable to becoming illegal trade commodities, primarily through domestic and international sea routes. Therefore, endemic flora and fauna in Indonesia must be protected to prevent extinction. Customs is a community protector that monitors export activities through the law enforcement of CITES (Convention on International Trades on Endangered Species of Wild Flora and Fauna). This study aims to analyze the effectiveness of supervision carried out by Customs as a community protector in monitoring illegal wildlife exports through the prohibition and restriction supervision scheme at Tanjung Priok Port. The method used in this paper is qualitative research with a literature study approach. Based on the results of the data analysis that has been carried out, it can be concluded that customs have an essential role in the export of protected flora and fauna. For the supervision carried out by Customs to be effective and maximum, several steps are needed, including no collusion, computerization of services provided, and finally, implementing situational crime prevention against illegal wildlife trade.

Abstract

The ISPS Code was created in response to the terrorism that occurred on September 11, 2001, in the United States. This prompted the IMO to review and draft the ISPS Code, which was then agreed to be included in the amendments to SOLAS 1974. The function of the ISPS Code is to minimize the occurrence of terrorism, piracy, cargo theft, stowaways, drug smuggling, money laundering, and other related issues. Due to the numerous incidents, particularly in Indonesia, this study reviews the security risk of the XYZ Port Facility based on the ISPS Code. These research objectives are to determine the security risk rating of the XYZ Port facility and to ascertain whether risk mitigation measures are necessary for the security facilities of XYZ Port. The method used in this research involves surveys and direct observations based on field data. The risk assessment in this study consists of three evaluations: threat, vulnerability, and impact assessment. Based on this research it can be identified that the security risk assessment of XYZ port facilities across 9 aspects revealed that 7 out of the 9 aspects have a risk rating of "Document (D)," while the remaining 2 aspects have a risk rating of "Consider (C)”. Overall, it can be concluded that the security level of XYZ's port facilities is good.

Abstract

Optimizing the cross curves of ship stability through the application of Response Surface Methodology (RSM) requires a complex interplay between factors such as hull shape, beam, and draft significantly influences a ship's stability, which is crucial for the safety of the crew, passengers, and cargo. By employing RSM, this research systematically examines these factors, developing a second-order polynomial model to describe their relationship with stability metrics. The experiments were conducted using Design-Expert 13® software, which facilitated the design of experiments, data collection, model development, and validation. The optimized model revealed that while the overall impact of individual factors might not be significant, their combined interactions provide a robust predictive capability for ship stability. The results demonstrated that the optimized input variables led to improved stability outcomes, minimizing moment trim while maximizing longitudinal and transverse metacentric heights, thereby ensuring better performance and safety across various sea conditions.
