Abstract

One Hour Notice (OHN) is a critical procedure in ship operations designed to ensure readiness before the vessel conducts maneuvering activities such as departure, berthing, or handling conditions requiring heightened alertness. The implementation of One Hour Notice (OHN) requires effective coordination between deck and engine watchkeepers to ensure that all steps are carried out according to operational standards. This study aims to evaluate the watchkeeping officers’ understanding of the OHN procedure and assess its implementation on board MT. Pis Patriot, as well as identify potential obstacles encountered during its execution. This research employs a descriptive qualitative method supported by observation, structured interviews, and documentation. Informants include deck watch officers, engine watch officers, and the Chief Engineer. The research instruments consist of observation sheets, interview guides, and documentation checklists. Data were analyzed using the stages of data reduction, data display, and conclusion drawing based on the Miles and Huberman model. The results indicate that the officers’ understanding of One Hour Notice (OHN) falls into the “fairly good” category, although several inaccuracies remain regarding specific objectives and procedural sequences. The implementation of One Hour Notice (OHN) on board is generally effective but not yet fully consistent, particularly concerning time synchronization, inter-department coordination, and the completion of inspection checklists. Main obstacles include limited training, outdated SOPs, and insufficient routine evaluations by ship management. Overall, this study concludes that although One Hour Notice (OHN) implementation on MT. Pis Patriot is functioning adequately, improvements in theoretical understanding and procedural compliance are needed to fully support ship safety and operational efficiency.

Abstract

SOPEP is a box that is usually red or yellow and has the words SOPEP written on it and contains tools used to prevent oil spills, such as rags, sand, sawdust, oil spill dispersant (OSD), brooms, and buckets. SOPEP (Shipboard Oil Pollution Emergency Plan) is a plan for handling oil spills into the sea that every ship must have. MARPOL 73/78 Annex I, requires that all ships with GT 400 and above must (for tankers starting from GT 150 and above) be equipped with SOPEP equipment following the instructions given by IMO and MEPC (Marine Environmental Protection Committee). Sailing practice is carried out at MV.DK02. The method used in this research is the descriptive qualitative method. That is a research method that utilizes qualitative data and is described descriptively. The results of this study indicate that the constraints experienced by the kru when implementing SOPEP on ships were the kru's lack of knowledge about SOPEP and the tools in it, who should already be familiar with SOPEP tools and their uses.

Abstract

Gas carrier vessels have a high level of operational risk due to the characteristics of the cargo, which is volatile, pressurized, and can be toxic, such as ammonia. One of the important stages after cargo discharge is gas freeing, which is the process of removing residual gas vapour inside the cargo tank until it reaches a condition that is safe for entry. This process aims to ensure that the tank is free from hazardous gases so that it is safe for the crew to carry out maintenance or inspection activitiesThis study aims to determine the implementation process of gas freeing, identify the obstacles that occur, and analyze the efforts made to overcome these obstacles on LPG/C Coral Ivory. The research method used is descriptive qualitative with data collection techniques through observation, interviews, and documentation. Data analysis was conducted using a fishbone diagram to identify the factors causing the problems. The results show that the obstacles in the gas freeing process are influenced by material, method, and measurement factors. The efforts to overcome these problems include optimizing the warming-up process, adjusting inerting and purging gradually, and improving gas monitoring to ensure that the tank condition meets safety procedures.

Abstract

The captain is the highest leader on board a ship who plays an important role in managing, directing, and supervising all operational activities of the ship. In order for the work process to run optimally, a leadership style that can effectively encourage the performance of the crew is needed. This study aims to analyze the captain's leadership style and how it supports the performance of crew members during the execution of tasks on the MV Kairos Jaya 8 ship. This study used a qualitative descriptive method with data collection techniques in the form of observations made by the researcher during the study, interviews conducted with the captain, chief officer, and crew, as well as supporting documentation obtained during the researcher's PRALA implementation on MV Kairos Jaya 8. Data analysis was carried out using Fish Bone Analysis to identify the root causes The results of research conducted during sea practice (PRALA) show that the captain's leadership style greatly affects the quality of crew work, especially in terms of communication, discipline, and completion of daily tasks. It was found that inconsistency in giving instructions, lack of a persuasive approach, and poor two-way communication can lead to delays in work and decreased crew motivation. Conversely, when the captain applies a more democratic and supportive leadership style, the crew shows a significant improvement in performance, as seen in the accuracy of task execution and increased coordination among crew members

Abstract

Cargo hold preparation is an important factor in supporting the smooth implementation of cargo handling operations on board. Based on the results of Sea Practice conducted on MV. Kairos Jaya 8, it was found that cargo hold preparation had not been carried out optimally. The problems identified included delays in cleaning the cargo hold, lack of supervision from officers, inconsistent use of inspection checklists, and unstructured task distribution. This study aims to analyze the factors causing the suboptimal cargo hold preparation and to formulate improvement efforts that can be implemented. The research method used was descriptive qualitative, with data collected through direct observation, interviews, and documentation. The results show that the absence of a systematic Standard Operating Procedure (SOP), lack of coordination among crew members, and weak supervision were the main factors. Improvement efforts include developing and implementing SOPs, applying cargo hold readiness checklists, clarifying task distribution, and strengthening officer supervision.

Abstract

Shipping is an integral part of the national maritime transportation system and serves as a vital means of supporting the achievement of national development goals. According to the International Maritime Organization (IMO) 2019, passenger ships—including Roll-on/Roll-off (Ro-Ro) passenger ships—are required to utilize all available navigation aids, such as radar and ARPA, to conduct effective surveillance and assess the risk of collision. This study employs a descriptive qualitative method, with informants selected through purposive sampling, namely the Captain, First Mate, Second Mate, Third Mate, and Helmsman. Data were collected through interviews, observations, and documentation using interview and observation checklists. Data analysis was conducted through data reduction, fishbone diagrams, data presentation, and drawing conclusions. The results of the study indicate that the effectiveness of Radar and ARPA usage on the KMP. Wira Berlian is influenced by human, methodological, equipment, measurement, and environmental factors, including the vigilance of the officer on watch, radar configuration procedures, component condition, CPA/TCPA monitoring, as well as weather and vessel traffic density
