Abstract

The shipping industry faces challenges in reducing environmental impact and increasing operational efficiency. Among them are the expansion tanks on ship engines which play an important role in maintaining the pressure and water quality of the engine cooling system, which is still run manually on some ships. This can result in the risk of engine damage due to overheating or unstable pressure. Manual water filling that requires crew supervision can cause operational instability. This research designed a prototype of an automatic water filling system for expansion tanks, using microcontroller-based automation technology and an Internet of things system to make monitoring easier. This system aims to increase efficiency and reduce the risk of engine damage, thereby supporting the sustainability of ship operations in the future. In the trials that have been carried out, this tool is able to operate the expansion tank filling automatically and efficiently. The distance sensor used has high accuracy with a largest error of 1.6%, and an average error of 0.01%. Integration with the Internet of Things system can run well and reliably with 100% success and latency of 0.5 – 1 second. The system's overall success rate is 80%. So the system can be used in real working conditions

Abstract

One of the most common obstacles is the difference in the amount of coal transported during the transhipment process compared to before the transhipment was carried out. This difference tends to lead to a reduction in the amount of coal (shortage cargo) which is certainly very detrimental to the recipient company which causes the transhipment process to occur more than once, thus disrupting the company's schedule and operations, resulting in the parties involved experiencing financial losses. This study was conducted to determine the influence of draught survey factors, hydrostatic table and cargo losses and how the influence of each factor simultaneously causes cargo shortages in transhipment activities, testing using comparative causal quantitative research methods using multiple linear regression data analysis techniques which were then processed using the SPSS version 23 program. The results obtained indicate that there is an influence of draught survey, hydrostatic table and cargo losses on transhipment activities and partially have an influence of 9%, 1.6% and 2.5% respectively. The variables of draught survey, hydrostatic table and cargo losses simultaneously cause cargo shortages so that it affects transhipment by 71.2%. while the remaining 28.8% is suspected to be influenced by other factors outside the research variables.

Abstract

In order for life to exist on Earth, water is required and is particularly important on ships. Concerns about water scarcity arise because water resources cannot always meet demand. pH has an impact on the quality of drinking water, with an ideal range between 6.5-8.5. Alkaline water with a pH of 8.8 has health benefits, including helping to lower stomach acid and improve body oxygenation. The pH of drinking water recommended by the EPA is between 6.5-8.5 to ensure safe consumption. pH is a measure of the acidity or basicity of water, on a scale of 0-14, where 7 is considered neutral. The research plans to make a drinking water pH control system using an ESP 32 microcontroller. This research aims to control also monitor the pH of drinking water efficiently using ESP 32 microcontroller. This research uses the Research and Development (R&D) method to design pH control in drinking water solutions. The phases of the research include using a pH sensor to detect pH values, using an ESP 32 microcontroller to control pH, and validating and improving the product model. Overall system testing in the design of a drinking water pH controller system from water treatment is an important stage to ensure successful integration between all components and desired functionality. This testing process includes several main stages, Hardware Integration Testing: All hardware is physically connected and integrated, including ESP32, relays, solenoid valves, and pH sensors. This test is taken to ensure that all components are properly installed and interact with each other correctly. Software Integration Testing: This type of testing verifies that all features and functions of the system function as intended by the software program responsible for it. This includes testing Wi-Fi connections, integration with the Blynk platform, and programming logic as an automatic water controller. Testing System Functionality: to ensure that the intended features can be run properly, the system is tested in various usage scenarios. This includes testing the water controller automatically. the designed system can function normally and adjust appropriately to the designed controller system. From the data obtained regarding the performance results of the system built, it was found that the pH controller system can be run automatically based on the water that has been set as the set point of the system created. The monitoring system with IoT is also able to run well. The time needed will be more to control the pH in the range of 6.5-8.5.

Abstract

Unloading equipment is equipment used to assist the process of loading or unloading cargo, such as cargo or bulk cargo from transportation facilities. One example is a conveyor, a mechanical system that can move goods. However, damage often occurs to the conveyor, so an Arduino Mega-based safety device was designed to fulfill the safety aspect. The aim of this research is to find out how to design an Arduino Mega-based safety device system for conveyor unloading equipment using the Research and Development (R&D) method. Using 2 types of testing, namely: static and dynamic testing. Arduino MEGA works fine. If the motor rotates and the conveyor moves, the conveyor is said to be working properly. The safety device on the Arduino Mega-based conveyor was made using Arduino IDE software using the C++ programming language. This safety device is able to secure the conveyor when damage occurs by cutting off the electricity when there is an overload on one of the conveyors so that the entire conveyor stops working. The conveyor series consists of a power supply, box panel, and three conveyors. After the tool has been tested and can work well, the testing is complete and the tool is ready to be used.

Abstract

Grounding incidents are among the most critical maritime accidents, posing significant threats to navigational safety, operational efficiency, and logistics continuity. This study aims to analyze the contributing factors behind the grounding of MV. Tanto Luas in the Mahakam River and to identify effective mitigation efforts. A descriptive qualitative approach was employed, with data collected through direct observation, interviews with ship crew, and documentation during onboard sea practice (PRALA). The findings reveal that the grounding incident was primarily caused by poor communication between MV. Tanto Luas and a tugboat, improper navigational decisions, and shallow, wave-affected waters. The Fishbone Diagram (Cause and Effect Diagram) method was used to systematically identify the root causes of the problem. Mitigation efforts included tank sounding, tidal monitoring, optimal use of navigational equipment, and improved inter-vessel coordination. The study concludes that grounding incidents can be prevented through enhanced communication, strict adherence to navigational procedures, and regular crew training. This research offers both practical and theoretical contributions to the enhancement of maritime safety in narrow waterways such as the Mahakam River.

The implementation of loading and unloading occurs various obstacles that often slow down loading and unloading activities, especially in the 3T (Underdeveloped, Frontier, and Outermost) areas. The equipment and facilities available by the port greatly affect how fast or slow the loading and unloading activities take place. This study aims to determine: 1) What are the factors that cause delays in the loading and unloading process of containers in the 3T area 2) What efforts are made by company and port management in overcoming delays in the loading and unloading process of containers in the 3T area. The method used by the researcher this time is descriptive qualitative. Primary data in this study were obtained directly through interviews, observations (observations) and also documentation. The main factors that are the main causes of why loading and unloading activities in the 3T area are ineffective and inefficient, namely the lack of adequate loading and unloading equipment and port facilities, the lack of human resources and skills from TKBM, as well as geographical conditions and bad weather. This situation causes loading and unloading activities to be ineffective.
