the ship. Ship maneuvering, on the other hand, refers to the ability to turn and pivot while sailing. This ability is crucial for the safety of the ship, especially when operating in restricted waters or near ports. The blackout occurs as a result of generator overload or the inability of an electrical voltage and current to flow too high or too large. The load is too high because the bow thruster consumes too much electrical voltage. In fact, on KM. Dharma Kartika IX, the generator has already supplied a significant amount of electricity to various parts of the ship, including the lighting system throughout the ship, from the mast to deck 3, the cooling system, and several navigation systems. The aim of this research is to understand and explain the causes of blackouts in the electrical system of KM Dharma Kartika IX during maneuvering and to find solutions that should be implemented in case of problems with the generator unit. The method I used to gather this data is through direct observation during seagoing service on the subjects under examination.

on Damer’s theory. The method used in this study is qualitative descriptive. Data has been collected in the analysis by way of presenting, describing, and interpreting data. Research results show that there are twelve data in in this study, such as structural principle (twelve data), relevance (ten data), acceptability (one Data), sufficiency (six data), and rebuttal principle (four data). The researcher found that the structural principle is most dominantly used in the argument because there is a claim from the speaker’s argument to strengthen the speaker’s statement so that it can be accepted by the audience, relevance of reasons that are directly related to the claim, acceptability of the audience's opinion regarding the speakers’ argument, sufficiency provides evidence to strengthen the argument, and rebuttal principle which is the speaker's criticism of the argument presented by the opponent. Therefore, this concluded that the most consistent during the debate was Randa saying that quotas can help gender equality while Christina said that quotas cannot work and only harm because there is no evidence that gender quotas can help equality.

r criteria that need to be considered, including the distance to the location, the level of logistic needs, the number of personnel at the location, and the availability of logistics in the warehouse. Additionally, difficulties frequently arise in determining priority locations during emergencies or disasters, as well as vulnerabilities to subjective errors due to human limitations in analyzing complex data. Another issue is the unequal allocation of logistics, where some locations receive more logistics than needed, while others experience shortages. A Decision Support System (DSS) is a computer-based system designed to assist decision-makers in analyzing data, evaluating various alternatives, and providing recommendations. DSS aims to simplify the decision-making process to make it more effective. Various methods are used in the decision-making process, one of which is the Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) method. This system aims to reduce subjectivity, increase efficiency, and ensure a more equitable allocation of logistics based on needs. It is expected that this DSS can serve as a solution that facilitates faster, more accurate, and transparent decision-making.
