Abstract

Ship repair is a project that is short in process so that time is an important element in its completion parameters. Delay is something that can happen to a job. A job experiencing delays must have a cause that affects the work. Causes of delay in the case of ship repair are poor time management, less skilled human resources, the addition or development of work. But whatever the obstacles, shipyards are still required to complete the ship repair process in a timely manner. Seeing this problem, this research was conducted to provide input in connection with the strategies used by PT XYZ in overcoming the delay factor in the repair of the KM Binaiya ship. In the research to support this thesis, the Bayesian Networks Method is used to analyze the factors that cause delays in ship repairs. After risk identification using the Bayesian networks method. The highest risk is replete activities as minor categorized, where the caused tank cleaning work related to hazardous waste, which must be cleaned to be safe for hot work with a risk score of 0.108. The second cause is installation of scaffolding for replete work facilities at height with a risk score of 0.054.

Abstract

Glass fibre vessels in Indonesia, which has thousands of islands, are increasingly used due to their relative low price, light weight, corrosion resistance, and low maintenance costs. However, the aggressive marine environment such as exposure to salt water, ultra violet light, temperature changes, and repeated mechanical loads, affect the service life of this material. Determining the mechanical characteristics of glass fibre vessels is important to prevent structural damage that compromises safety and operations. The purpose of this research is to identify and analyse the condition of shipyards, fibreglass vessels that have been in operation, and examine the mechanical characteristics of glass fibre vessels. The research methods used are literature studies and field surveys to shipyards, glass fibre ships, and testing mechanical characteristics with tensile tests and bending tests. The results obtained from this study are the identification of the condition of the glass fibre shipyard, the condition of the operating glass fibre ship, and the mechanical characteristics of glass fibre ships mostly do not meet the standards of the Indonesian Classification Bureau. Recommendations to improve the quality of production are the location, method, labour, design and materials such as ship resin and laminate layers used during the production process have met and obtained certification set by the Indonesian Classification Bureau.

Abstract

Marine conservation areas in small island environments require compatibility between management zoning and local physical oceanographic conditions to function effectively and sustainably. Gili Ketapang, located in the Madura Strait, has been designated as a Marine Conservation Area under the Decree of the Minister of Maritime Affairs and Fisheries No. 64/KEPMEN-KP/2020. However, evaluations of zoning suitability based on physical oceanographic characteristics remain limited. This study aims to assess the suitability of zoning within the Gili Ketapang Marine Conservation Area using key physical oceanographic parameters, including currents, waves, tides, and wind. Tidal analysis was conducted using the Admiralty method to determine tidal type and sea level characteristics. Wave and current data were obtained from Copernicus Marine Reanalysis with a 3-hour temporal resolution over a ten-year period, while wind data were used to support seasonal analysis. Zoning suitability was evaluated by comparing the analyzed oceanographic conditions with relevant criteria for coastal and marine utilization. The results indicate that the waters of Gili Ketapang are characterized by a mixed, mainly semidiurnal tidal regime, with a Formzahl value of 1.3. Seasonal variability in currents and wave conditions reveals periods that are less favorable for utilization activities in certain sub-zones, particularly within the Aquaculture Sub-Zone. These findings suggest that zoning suitability is dynamic and strongly influenced by seasonal oceanographic variability. This study highlights the importance of integrating long-term physical oceanographic analysis into the evaluation and management of marine conservation zoning, especially in small island environments with high hydrodynamic dynamics.

Abstract

The operational readiness of warships is closely linked to the reliability and performance of their propulsion systems, whereas aging naval platforms commonly experience degradation that reduces operational effectiveness and increases maintenance requirements. This study aims to formulate a propulsion system modernization strategy through a repowering program for KRI X. A descriptive qualitative design was applied using primary data from in-depth interviews with seven purposively selected informants and observations, supported by secondary data from document analysis. Interview data were coded and analyzed using NVivo 12 Plus, while internal and external factors were evaluated through SWOT analysis. The results show significant degradation in the main engine, gas turbine, gearbox, and controllable pitch propeller (CPP), which adversely affects speed, endurance, maneuverability, propulsion reliability, and operational readiness. The SWOT analysis positions the program in the Weaknesses–Opportunities (WO) quadrant, indicating a Turn-Around Strategy that uses modernization opportunities to overcome internal weaknesses. Repowering is therefore an appropriate strategic and cost-effective approach to improve propulsion reliability and long-term operational readiness, provided that it is supported by logistics, maintenance, personnel competence, and organizational policy.
