Abstract

Small and slender boats are usually installed with outrigger as additional construction to enhance its stabilities. The same practices are found in Palabuhanratu fishing port. The massive use of outrigger in most fishing ports, including Palabuhanratu, have led to berthing problems due to limited area of the port basin, hence boat or outrigger modification is required to overcome the problem. Adjusting the hull slenderness by defining the proper breadth and depth (B/D) ratio can be potential approach to eliminate the outrigger. Therefore, this research is designed to define ideal B/D ratio for boat without outrigger based on its stability, resistance and seakeeping in accordance with operational purpose. The study was conducted by simulating three different B values with constant D, each of which experiencing two different operational conditions, half and full loads. The quality of boat stability was evaluated in five parameters defined by IMO, whilst the resistance performance was evaluated using comparison analysis, and the seakeeping performance was evaluated using wave height and wave arrival angle. The result showed that according to its operational purposes, the boat with B/D ratio of 1,71 has the best performance to be operated without outrigger

Abstract

Climate change that is happening at this time affects the decrease in the availability of water in the world. Urban areas, especially coastal areas, will have a more significant impact on water scarcity. Coastal areas in Indonesia, such as Bandar Lampung City, are mainly concerned in this study. Therefore, a study was conducted to determine the variables that influence water conservation practices in Bandar Lampung, which focuses on social psychological factors with four independent variables. By knowing the independent variable that has the highest level of influence, an approach to conservation efforts at the individual level can be approached. Data were obtained using a closed questionnaire with answer options using a Likert scale. Data analysis used simple linear regression and stepwise regression. The simple linear regression results show that the variable social norms (X4) are the highest variable with a value of R2 0.0385. In stepwise regression, the variable attitude towards conservation (X1), the benefits obtained (X2), individual control behavior (X3), and social norms (X4) simultaneously have a coefficient of determination value of R2 0.06127, where the social norms variable align with sample linear regression results on water conservation practices. These social norms can be used as a reference by stakeholders such as Perumda, Regional Government, NGOs, etc., through individual approaches in mapping strategies for increasing water conservation practices.

Abstract

Fire accident onboard RoRo (Roll on/Roll off) passenger ferry notoriously indicates intense symptoms of human, technical and organisational issues. In some cases, the more complex the fire's origin, the more challenging the crew would handle handling, suppressing, and putting out the fire. The crew response plays a significant role in the success of firefighting onboard. The research focuses on evaluating the effectiveness of fire drill performance by developing an evaluation model based on the cognitive model and analytical network process. The model was developed to overview crew performance and consistency in conducting fire drills on board the roro passenger ship. The questionnaire is developed to obtain crew perspective and awareness of fire risks. The analytical network process (ANP) model is utilised to identify crew preference during fire drills. The result of decision-based research identified significant issues that occurred in every step of cognition. Competency and proficiency of the crew, along with continuous training and familiarisation, were the main issues in improving effectiveness in firefighting. The results of the analysis were resourceful evidence to enhance audit and supervision for the emergency preparedness system. In addition, it is also a reference for developing further training models to improve crew overall performance in firefighting.

Abstract

The mutual interaction between humans and animals in the field of ethnozoology includes uses that can be oriented toward conservation or exploitation efforts. However, excessive abuse of sea turtles (Chelonioidea), especially in the direction of exploitation, has led to population decline and threatened their extinction. Observations in the Derawan Island community, Berau Regency, show a decrease in the number of turtles coming to lay their eggs due to overexploitation. To overcome this problem, it is necessary to carry out research that looks for factors that influence attitudes and behavior in using turtles, including the level of ethnozoological knowledge and family economic status. This research uses a quantitative approach with an analytical correlational design and applies Path Analysis. The results of the analysis show that the level of ethnozoological knowledge has a significant influence on attitudes, with a path coefficient of 0.298 in block-1. In block-2, the results of the analysis show that the level of ethnozoological knowledge directly influences turtle utilization behavior with a path coefficient of 0.313. In conclusion, the level of ethnozoological knowledge has a dominant role in shaping turtle utilization behavior in Derawan Island

Abstract

The Application of the Marine Pollution (MARPOL) Annex IV regulation concerning sewage discharge from ferry ships operating on the Ketapang-Gilimanuk route plays a crucial role in pollution prevention. However, this essential role has been compromised due to suspicions that sewage waste from the Ketapang-Gilimanuk ferry ships is being directly discharged into the sea. Additionally, it is believed that the lack of sewage storage facilities at the port and inadequate supervision by local port authorities contribute to this issue. This research aims to investigate the implementation of MARPOL Annex IV in pollution prevention on ferry ships along the Ketapang – Gilimanuk route using the Analytical Hierarchy Process (AHP) method. This method is employed to establish a comprehensive evaluation framework by considering criteria such as safety management systems, safety and environmental protection policies, Company responsibilities and authorities, cultural and behavioral aspects, organizational factors, and technical considerations. Data will be collected through surveys and interviews with ship operators and members. Economical is more priority than operational techniques because it is related to capital expenditure and operational costs of each alternative to prevent marine pollution. Operational techniques are more priority than safety and environment because they are related to the technical and operational of each alternative to preventing marine pollution. Regulations are more priority than safety and environment because regulations affect each alternative, both Indonesian regulations and also SOPs at ports.

Abstract

This research explores the pervasive issue of cyberbullying, primarily targeting children and teenagers due to their close proximity to communication technologies. Cyberbullying manifests through various forms such as flaming, harassment, and identity impersonation, causing significant psychological and academic impacts on victims. The study, based on a selection of 30 Scopus publications, reveals that cyberstalking holds the highest classification at 90%, followed by flaming at 73%. The consequences of cyberbullying are classified into social (67%), psychological (63%), and academic (57%) impacts. The research emphasizes the need for specific knowledge about cyberbullying in coastal communities, where victims experience feelings of insecurity, isolation, and reduced academic concentration. The conclusion highlights the importance of raising awareness, implementing literacy programs, and enforcing regulations to combat cyberbullying, especially in the context of the Fourth Industrial Revolution. The findings provide valuable insights into the coastal community's perception of cyberbullying, urging parents to play an active role in safeguarding their children and promoting digital literacy.

Abstract

The process of building a ship or offshore structure, proper and accurate planning and implementation is required. In the development process, it will go through a stage, namely the construction stage. At the construction stage, the construction of a ship or offshore building will go through a welding phase which functions as a connection of materials to one another. Low carbon steel and stainless steel are materials that are often used in the construction process of ships or offshore structures. In this study, an analysis of the effect of the combination of electrodes on the welding of steel and stainless steel materials was carried out in terms of mechanical properties such as tensile strength, bending strength and metallographic shape. The materials used in this study were A36 steel and 304 stainless steel, while the electrode combinations used were E308L and E309 electrodes. Welding variations used in this study were a combination of E308L (root) and E309 (filler) electrodes, a combination of E308L (filler) and E309 (root) electrodes, E309 electrodes, and E308L electrodes. In the tensile test results it was found that the highest tensile strength value occurred in Specimen 4 with an average value of yield strength and ultimate strength of 389.54 MPa and 522.52 MPa. The tensile strength value is influenced by the amount of chromium contained in the electrode. This is because the higher the amount of chromium causes the amount of ferrite in the material to increase so that the tensile strength value decreases. In the metallographic macro testing results, the best weld profile results were obtained on specimens with the ME 4 material code because the results of the weld profile shape best met ASME Section IX standards. The results of micro metallographic testing showed that welding using the dominant E308L electrode as in Specimen 1 and Specimen 4 obtained a higher ultimate strength value compared to Specimen 2 and Specimen 3. This was due to the influence of chromium on the electrodes used, high chromium causing the formation of a ferrite phase in the microstructure of the material.

Abstract

Indonesia's geographical conditions and position are very favorable and various policies from the government from 2005 until now are expected to become the shipyard industry to become a tough industry, but in reality it is still not as expected. The condition of the domestic shipyard industry in 2017 until now there is only ship repair and maintenance work, while orders for new ships or buildings are very few and even zero demand ship orders, causing business continuity in the shipyard industry to be disrupted and even out of business. This paper aims to develop a concept for the development of a multi-oriented shipyard industry that is environmentally friendly and sustainable. The preparation of this concept begins with identifying problems, collecting secondary data, reviewing related articles (shipyard industry, ship recycling yard industry, environment, sustainability, and supporting methods), analyzing and developing a development concept. The results obtained from drafting the concept are in the form of a diagrammatic model for the development of a multi-oriented shipyard industry that is environmentally friendly and sustainable. The development concept consists of (1) research background in the form of the existing conditions of the shipyard industry, ship recycling industry, geography, infrastructure, superstructure; (2) research that has been conducted in the form of relevant journal articles and proceedings; (3) research to be conducted in the form of sustainability criteria, orientation diversification and strategy selection; (4) implementation.

Abstract

The hot temperature on the ship will interfere with the comfort of the crew, so an air conditioning machine is needed to cool down. Hot conditions make air conditioning needed on the ship as a means of cooling when the ship sails. Split AC performance is very necessary so that the temperature released remains optimal. Split air conditioners have many components, for example, capillary pipes, capillary pipes play a very important role in obtaining low temperatures. Therefore, it is necessary to research variations in the length and diameter of capillary pipes. As a pressure-lowering device and regulating the amount of refrigerant liquid flowing, the length and diameter of capillary pipes greatly affect the cooling process. If you find the right and right variation, you will get a temperature lower than the standard Therefore, to get extra cooling for split air conditioners, research is proposed on the effect of variations in the length of capillary pipes on the work performance of split air conditioner machines using R32 refrigerant for ship accommodation room. To know the effect of cooling more extra because with changes in capillary pipes further maximize cold temperatures by using additional capillary pipe length. This study uses an experimental method with a split air conditioner 0.5 Hp as the main object and variations in capillary pipe length. the temperature after the capillary pipe is varied is lower than the standard, namely the standard achievement of 55.9 for a variation of 72 cm, which is 26.4, and the last variation of 159 cm, which is 29.
