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

This study investigates the problem of sedimentation in the Porong River and the Eastern Surabaya Shipping Lane by taking a close look at the Amphibious Multipurpose Dredger. The study examines the vessel's parameters (length: 14.30 m, breadth: 4.70 m, height: 1.60 m, draft: 1.10 m) in light of the requirements of coastal reclamation. For stability and pressure studies, manual calculations and Finite Element Method simulations are utilised. The results show that the hollow Spud design is superior to the alternatives in terms of material efficiency (Safety Factor: 12.4032). The research makes a substantial contribution by offering an effective way to address sedimentation issues through improved dredger design. Moreover, it emphasizes the crucial part that an adaptable amphibious multipurpose dredger plays in reducing sedimentation. The study highlights the strategic significance of the recommended spud design, satisfying safety regulations and improving operational efficiency, as coastal ecosystems face rising challenges.

Abstract

Abstract The depletion of fossil fuels is one of the reasons for using alternative fuels such as biodiesel fuel. However, biodiesel has disadvantages such as higher density, lower heating value, high fuel consumption, and high nitrogen oxide (NOx) content compared to diesel. To improve this, it can be done by increasing the cetane number of the fuel by adding citronella (C) oil as a bioaditive. The purpose of this study is to determine the characteristics of biodiesel fuel after adding citronella oil, and to determine the effect of citronella oil addition on engine performance, vibration, noise and emissions. This research was conducted experimentally by adding citronella oil with variations in composition of 0.5%, 0.75%, 1%, 1.25%, and 1.5% of the volume of Biodiesel fuel (B30). The fuel was tested on a Yanmar single-cylinder diesel engine. Experimental results showed that the cetane number increased with the addition of citronella composition, with the highest cetane number in B30+C 1.5% fuel, which increased by 25.9% when compared to the cetane number of B30. From the performance test results, the diesel engine experienced an increase in performance in the form of power, torque, BMEP, as well as a decrease in vibration and noise when compared to B30 fuel. The lowest NOx emissions occurred at 2000 RPM with the largest load produced by fuel that had added citronella 1.5% with a decrease of 21.6% when compared to B30 fuel.

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

In the operation of a multipurpose terminal in a port (terminal that can serve and be berthed to more than one type of a ship), the position of planning an optimal berth allocation for ships is essential to maintain. Berth allocation planning (BAP) is considered tactical planning that can impact the performance of a terminal and the cost of a ship in a port. That is because the longer the waiting time of a ship that waits to be berthed, the smaller number of ships will be served by the terminal, and the higher the cost will be borne by the ships. This paper, based on a case study in Terminal Jamrud of Tanjung Perak Port of Indonesia, will discuss a Mixed Integer Linear Programming (MILP) mathematical model of a BAP to minimize the ships’ waiting time to berth with consideration to the tailored conditions of the multipurpose terminal. The results show that the optimization model yielded reductions in the datasets 1 to 3 tested on the North/West and 4 to 6 on the South pier. There are savings in the waiting time reduced in hours, which are 403 (12,82%), 189 (26,18%), 418 (30,74%) for the North/West pier and 34 (16,43%), 1663 (88,13%), 475 (46,75%) for the South pier.

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

South coasts of Java have a unique landscape that exhibits exotic and phantastic natural view which is very attractive as tourist destinations. Indonesia has the world’s longest coastlines, the world’s highest coral diversity, and spectacular seascapes, therefore Indonesia’s coastal tourism potential is very promising. However, despite their attractiveness coastal water can be very dangerous to their visitors due to rip currents which isinhospitable to them. Klayar Beach (KB) is one of the most popular recreational beaches in Pacitan Regency, East Java Province, Indonesia. However, KB poses a hazard due to rip currents. This paper presents the result of field observations of rip currents utilizing fluorescent dying and unmanned aerial vehicle (UAV).  We used UAV multirotor DJI Mavic 2 Zoom with video camera to take and monitor aerial photo and video of rip current flows. The result of this study proves that there is rip currents in KB. It also reveals that the maximum velocity reaches 0.8 m/s, with average width of 11 m, and total length 99.99 m. The type of rip current in the KB is structural boundary controlled and predicted as a permanent rip. Therefore, this evidence should be considered for promoting beach safety in this area.
