Abstract

This research article examines the process of delaying service at West Opel through observations made while working on board the ship. This study focuses on two main factors that affect the efficiency of the towage process: the delay in maneuvering the ship and the time it takes. The observations highlight the impact of the power limitations of conventional tugs compared to ASD tug systems, particularly MVs. Ace Guard. This finding reveals that the insufficient power of a conventional vessel impedes the smooth maneuverability of the vessel, so that the ASD tug has to adjust its power to match that of a conventional tug and maintain the correct position while the vessel departs. In addition, this study emphasizes the significant duration of time involved in the towage process, taking into account the coordination between ASD tugs and conventional tugs. This research concludes that these factors contribute to a slower and more time consuming procrastination process. The case studies presented provide valuable insights for optimizing and increasing the efficiency of service operations in a similar maritime environment.

Abstract

Geothermal energy is a renewable energy source that can be used to generate electricity, heat homes and businesses, and provide hot water for industrial processes. The interior of the Earth is hot, and this heat can be transferred to the surface through geological structures such as faults, fractures and sedimentary basins. These structures provide pathways for geothermal fluids to flow, and they can also trap these fluids, creating geothermal reservoirs. The type and size of geological structures that affect geothermal energy can vary depending on the location. For example, in some areas, faults and fractures are the most important structures, while in other areas, sedimentary basins are the most important. The distribution of these structures also plays a role in determining the potential for developing geothermal energy. The study of geological structure is very important to understand the distribution and potential of geothermal energy resources. By understanding how these structures influence the circulation and accumulation of geothermal fluids, we can develop and better manage these resources. This abstract provides a brief overview of the topic of geothermal energy and the role of geological structures in this field. It is intended to provide a starting point for further research and discussion.

Abstract

This study aims to analyze the effectiveness and the economic side of the process of manual or semi-automatic bending signs. The data required for both types of marking methods are data on the number of operators, company working hours, effective working hours, and the results of the production process. After that it is done by data processing, data processing in this study uses the Experimental Method, in the Manual marking process, the process is done by directly drawing on the multiplex material according to the drawing design using 2 operators, in the Semi Automatic marking process, the use of a CNC machine is done by using only 1 operator and also using a setting on a CNC machine of 50 Amperes. So from the data that has been managed later, it shows that the use of CNC machines as a substitute for manual marking has a positive effect on the company. Which can reduce the amount of operator usage, get more results from the Manual marking process, and use less electricity. So overall, the marking process using the Semi Automatic method is better from all sides compared to the marking process using the Manual method.

Abstract

Shipyards are often difficult to find information quickly and efficiently on every component of the workplace. A good information system is actually needed for the work process in the shipyard because the project head's planning for the distribution of the project workload being carried out will result in a smooth production process, which will affect the completion time of the work to be carried out. Each of these stages is the final result stage where at this stage the author will draw conclusions to answer the formulation of the packing report based on writing which is prone to loss and damage. The development of an android-based ship repair information system that can be used to quickly and accurately report data required by the central supervisor allows for full monitoring of the new ship building process, which is standard practice in many shipyards that have a research methodology to solve the problem.
