Abstract

Renewable energy is increasingly popular and in demand throughout the world as an alternative to increasingly limited fossil energy, one of which is wind turbines. Wind turbine research on ships has great potential in developing renewable energy at sea. The aim of this research is to increase the efficiency of converting wind energy into electrical energy by designing a low cost wind turbine and analyzing the design efficiency of the wind turbine blade angle, namely 90˚, 95˚, 100˚. This research uses an experimental method with observation techniques, as well as measurement and recording as data collection techniques. This research was conducted on the Bung Tomo training ship for 3 days. The research results show that making a wind turbine using PVC as a base material costs Rp. 243,000.00 and produces the largest average voltage of 73.8 Wh. The influence of variations in the angle of the wind turbine blade can be seen that at an angle of 100˚ it has the largest average power output, namely 1.23 watts per minute and the battery charging time is based on an average current of 0.28 A, namely 12.5 hours when fully charged, whereas at The 90˚ angle produces the smallest average power of 0.76 watts per minute and the battery charging time is 16.6 hours when fully charged. So the 100˚ angle is more effective in charging the battery than the 95˚ and 90˚ angles. The greater the blade angle, the greater the rotation and produce greater voltage, this is influenced by the area of the turbine exposed to wind.

Abstract

A ship accident is an unwanted event that can cause material losses or casualties. In this case, the party who feels aggrieved can file a lawsuit to get compensation for the losses suffered. It is undeniable that ship accidents often occur due to various reasons ranging from human error, technical factors, force majeur factors and several other factors. This research aims to find out what are the causes of berthing incidents and to find out the efforts made by ship owners after incidents that occurred at the jetty. In this thesis, a qualitative descriptive method is used with a fishbone diagram approach. Observations, interviews and literature studies are carried out to collect relevant data to identify and explain the causes that arise and also the consequences they cause, so that they can answer the formulation of the problem that has been determined. The results of the study concluded that the lack of communication between the crew and the jetty as well as unfavorable weather conditions were the main factors causing the incident. The lack of effective communication contributes to poor coordination during the berthing process. In an effort to handle the post-incident, PT. Kartika Samudra Adijaya formed an investigation team, increased crew training and strengthened cooperation with the jetty and port authorities. This research is expected to contribute to improving operational procedures and reducing the risk of similar incidents in the future.

Abstract

To support the smooth operation of activities at the port and jetty, adequate facilities and operational systems are required. Long waiting times can reduce the efficiency of the loading and unloading process and hinder other operational processes. Delays can increase the operational cycle of ships, raise operational costs, and decrease port productivity. This study aims to examine the impact of ship waiting time on the efficiency of the coal discharge and loading process at PT. Adhika Samudera Jaya. Efficiency in the loading and unloading activities is crucial for increasing productivity and reducing operational costs. The research employs a quantitative method, with data collection through direct observation and documentation. The results indicate that the duration of ship waiting time significantly affects the efficiency of the discharge and loading process, where longer waiting times lead to longer loading and unloading durations. Key factors influencing waiting time include equipment readiness, weather conditions, shipping management, and cargo availability. By improving operational planning and speeding up facility readiness, the efficiency of the coal discharge and loading process can be optimized. This finding is expected to serve as a reference for companies and port authorities in improving the quality of coal loading and unloading services.

Abstract

As an archipelagic country, Indonesia has significant potential for the utilization of renewable energy, particularly wind energy in maritime areas with low wind speeds (3–6 m/s). This study aims to design and test a vertical Savonius wind turbine system equipped with a Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) algorithm as a power source for shipboard water heating systems. The research method applied is Research and Development (R&D), integrating several components such as a DC generator, full-wave bridge rectifier, INA219 current sensor, anemometer cup sensor, ESP32 microcontroller, and a monitoring interface utilizing Google Spreadsheet and a 20x4 LCD. The system was tested under two operating conditions: without MPPT and with MPPT. The experimental results show that the application of the MPPT algorithm successfully increased power output by up to 272.64% while maintaining voltage stability despite varying wind speeds. Nevertheless, the average output power of 2.605 W remained insufficient to meet water heating requirements within a short time. For example, charging a 12V 50Ah battery would require approximately 9.6 consecutive days of operation, highlighting the system’s limitations in high-demand scenarios. Despite these constraints, the findings demonstrate that the vertical Savonius wind turbine integrated with MPPT has strong potential as a clean and environmentally friendly alternative energy solution for maritime applications, particularly for small-scale onboard electrical loads. This study contributes to renewable energy utilization in the shipping sector and provides a foundation for further technological development and optimization.
