Abstract

Kepulauan seribu are also a frequently visited destination for domestic and foreign tourists and are among the priority destinations in Indonesia. The development of the passenger port in Muara Angke is an important step in supporting the tourism sector in Kepulauan Seribu. However, this development must also consider environmental impacts, including carbon emissions and the use of natural resources. Indonesia has taken steps towards developing renewable energy and policies that support it by implementing renewable energy at the Muara Angke Passenger Port will be in line with government initiatives to achieve energy targets national renewable. The method used is primary data, secondary data, by calculating the need for solar panels and wind turbines and collecting supporting data sourced from related websites. The results are 324 solar panels placed on the roof of the main building of the port where the wind turbine is placed on the west side. with a total of 6 units, on the east side of the port there are 6 units and on the south side of the port there are 4 wind turbine units

Abstract

Based on the provisions made by the International Maritime Organization (IMO), turning ability and zig-zag maneuvers are the main criteria for safety standards for every ship that will sail. This decree was made as an effort to improve sailing skills, especially for ship crew. Calculation of the turning ability of a ship is greatly influenced by the design of the ship's hull and the design of the rudder that will be used on the ship. So the analysis of turning circles and zig-zag maneuvers is the main point that will be carried out in this research. The research was carried out on cast net vessels anchored at the Muara Angke fishing port with the vessel size taken being 60 GT. The standard provisions used in the analysis of turning ability and zig-zag maneuver are based on IMO MSC 137 (76) with the main size of the vessel used as the main research material is LOA=25.7 m, LPP =22.2 m, B=7 m, H=2.3 m, T=1.7 m. With the results obtained by the movement of the fishing vessel which meets standardization based on IMO MSC 137 (76) 2002, the turning circle maneuver has a Tactical Diameter of 46.07 m, with an Advanced value of 56.23 m, with a heading transfer value of 24.48 m, the zig-zag maneuver meets the IMO standard criteria stated for angels 10°/10° and 20°/20° do not exceed 30 seconds

Abstract

Chlorophyll-a is one of the important water quality parameters in the sea. This research was conducted in April 2022 in the Belawan Waters of North Sumatra Province with the aim of knowing the level of chlorophyll-a concentration in these waters. The method used is survey and extraction of Aqua MODIS satellite image data into ASCII data and image data using the seaDAS application. The value of chlorifyll-a concentration obtained in Belawan waters is 3.35-5.91 mg / m³ and has an average value of about 4.65 mg / m³. Belawan waters in April 2022 experienced high chlorophyll-a concentrations.

Abstract

The knowledge and skills of a ship's crew can play a key role in preventing collisions. The Bridge Watchkeeping Duty becomes crucial in this context, as they are the first to detect potential threats. Given the increasing risks in maritime transportation and the need to prevent ship collisions, several steps can be taken. One of them is to effectively carry out the tasks and functions of the Bridge Watchkeeping Duty. Therefore, this study aims to analyze the Bridge Watchkeeping Duty, specifically, the efforts to prevent sea collisions conducted by the Ship's Bridge Watchkeeping Service, and how its theoretical and practical implementation is carried out in the field. This qualitative study uses a descriptive method to describe and elaborate on the study object, namely the John Lie training ship. The study will include quotations from various data sources such as interviews, field notes, memos, and other official documents. Data analysis in this study uses the techniques of Miles and Huberman. The results of this study indicate that the implementation of these duties and responsibilities must always be based on a deep understanding of various national and international maritime regulations, as well as knowledge of the characteristics of the ship and its surrounding environment. Additionally, implementing regulations such as the 2010 Manila Amendments to the STCW 2010 is also important to ensure the welfare and fitness of the watchkeepers so they can perform their duties and responsibilities optimally. This study has several limitations, such as variables that need to be explored further, such as the psychological aspects of bridge watchkeepers who bear a heavy workload, extreme sea weather conditions, and ship facilities that support collision prevention activities. Thus, this study is expected to provide constructive thoughts and suggestions for maritime transportation stakeholders, particularly sailors and crew members, regarding the importance of properly implementing the Bridge Watchkeeping Duty. Focus on the human aspect in preventing ship collisions at sea through the Ship's Bridge Watchkeeping Service.

Abstract

Over time, marine building technology has experienced very significant developments and there are several variations of improvements that can be made to suit needs and conditions. A ship's propeller is a ship component that often experiences collisions with hard objects floating in the water which can cause the blades of the propeller to experience damage such as bending, cracking or breaking. In this case, the propeller should be repaired immediately so as not to disrupt the smooth operation of the ship. Repairing broken propeller blades can be done using a welding process. Welding is a technique of joining metals by melting part of the parent metal and filler metal with or without additional metal and producing continuous metal. Underwater Welding is a welding process that occurs in wet conditions, meaning that the electrode and object are in direct contact with air, while Gas Tungsten Arc Welding (GTAW) is an electric arc welding process that uses an untreated electrode that does not melt. This research was conducted to analyze the welding measurement results of Gas Tungsten Arc Welding (GTAW) and Underwater Welding on brass materials. To support the analysis process, testing activities are carried out including tensile tests (tensile test), hardness tests (hardness test) and macrographic observations on the results of welding materials.
