Abstract

Indonesia is known as an “undersea paradise” because of its extraordinary wealth of marine biodiversity and fishery resources. With this nickname, coastal communities should have a decent life. However, in reality, their welfare is not in line with the wealth of marine resources, especially for fishermen. The lives of fishermen are often colored by economic challenges, weather uncertainty, and environmental changes that impact their welfare. This study aims to identify sources of livelihood, identify levels of welfare, and identify livelihood strategies carried out by fishing households. Through a survey that we conducted on 35 small-scale fishing households on the West Coast of North Sumatra, we found that most of them were still classified as less prosperous. Although the livelihood analysis shows that their sources of income are quite diverse, the contribution of income outside of fishing has not been able to improve their level of welfare. The results of this study also show that fishermen are not a passive group of people. Realizing the uncertainty in their livelihoods, they try to take advantage of existing opportunities by implementing livelihood strategies. The livelihood strategies carried out by fishermen are classified into economic dimensions, ecological dimensions, and social dimensions.

Abstract

More than a year has passed since Francisco Pérez-Arribas (2023) introduced a parametric-based hull design method using Python scripts, beginning with the cross-sectional area (CSA) design. Several experimental studies have been carried out to improve the method and the quality of ship design. This study aims to generate an optimal hull design by utilizing normal vectors derived from the x and y vectors. These normal vectors are applied parametrically to determine the shape of the hull. The study also employs a cubic spline-based parametric technique for designing yacht hulls. The purpose of this study is to introduce the concept of parametric design through the development of visual programming used to form cross-sectional area curves and generate hull geometry. This study also discusses both the advantages and limitations of using visual programming approaches to accelerate the design process. By varying the CSA shape of the DelftShip model, the resulting parametric model has a high level of accuracy, with a difference of - 0.097016% in LCB and -0.28785% in volume when compared to the DelftShip model. results from Grasshopper reveal significant differences, particularly below a draft of 0.475, where the CP values from Grasshopper are lower than those from DelftShip. The parametric approach using normal vectors not only facilitates design exploration but also holds the potential to enhance overall hull design quality and optimization.

Abstract

This study investigates the effects of extending the hull length of the KL Barombong training vessel, specifically on speed resistance, engine power requirements, propeller efficiency, and fuel consumption. The objective is to assess how these modifications impact overall vessel performance, particularly fuel efficiency and operational costs. Using Maxsurf simulation software, we analyzed the vessel's performance before and after the modification. Results show that extending the hull increased hydrodynamic resistance, requiring more engine power and raising fuel consumption by 12-15%. Additionally, the propeller efficiency declined due to the higher load. These findings emphasize the need for engine-propeller optimization during vessel modifications to ensure operational efficiency and sustainability. Recommendations for future modifications and system upgrades are also provided.

Abstract

The Polyculture Caulerpa sp and Litopenaeus vannamei can reduce the risk of ecological impacts, increase shrimp growth, survival, production, increase shrimp resistance to disease, and maintain optimal water quality. Analytical Hierarchy Process (AHP) begins by determining the priority between water quality, growth rate, and harvest yields as more optimal parameters for the success of a polyculture. The measure of success is determined based on the results of expert assessments of polyculture and cultivation that produce more optimal water quality (temperature, pH, brightness, salinity, and dissolved oxygen), growth rates, and harvest yields. The results of the overall AHP analysis, which determined the success of Caulerpa sp and Litopenaeus vannamei polyculture based on expert assessments, showed a good level of consistency. The results show that water quality is a priority parameter in the success of Caulerpa sp and Litopenaeus vannamei polyculture with a weight of 0.597, followed by a growth rate of 0.297 and a harvest yield of 0.106. The analysis of priority water quality indicators for the success of polyculture is dissolved oxygen with a weight of 0.514, followed by pH of 0.246, salinity of 0.119, temperature of 0.079, and brightness of 0.042. Based on the results of experts of the combined weight comparison, polyculture is more optimal than cultivation, with a considerable comparison weight of 0.678 and 0.322, measuring the success of Caulerpa sp and Litopenaeus vannamei polyculture.

Abstract

Along with the increase in trade activities by sea, the need for adequate port facilities, including the Container Yard, is becoming increasingly important. This study aims to analyze the needs of stacking yard facilities at Sorong Container Port. The research method used is a quantitative approach with data collection through documentation studies and observation at the research location, namely Sorong Container Port. The results showed that although the flow of containers is projected to continue to increase until 2026, the use of the stacking yard is still low with a Yard Occupancy Ratio (YOR) ranging from 12.43% to 14.59%. This indicates an opportunity to improve port operational efficiency. This study recommends optimizing the use of the piling yard, improving the loading and unloading process, developing infrastructure, and improving coordination with stakeholders. Further analysis of infrastructure investment and comparative studies with other ports are also recommended.

Abstract

As cities grow, the demand for energy increases, necessitating a corresponding increase in energy supply. Since urban areas consume the majority of the world’s energy, switching to renewable energy sources is essential. Wind energy is one of the most popular renewable energy sources for generating electricity. Vertical-axis wind turbines (VAWTs) are used in urban areas due to their advantages, with cross-flow wind turbines (CFWTs) being one type. However, the efficiency of CFWTs is relatively low, necessitating the application of augmentation devices. This study aims to find the optimal configuration between CFWTs and Omni-Directional Guide Vanes (ODGV), using 6DOF dynamic mesh methods in ANSYS Fluent with varying the turbine blade counts and the addition of ODGV. The results showed that the 18-blade configuration exhibits the highest improvement with ODGV, demonstrating a remarkable 71 percent increase in the power coefficient. In general, the highest performance is achieved by the 20-blade turbine with a 6-blade ODGV configuration, with a power coefficient of 0.2455, which is 30 percent higher than the baseline 20-blade turbine. These findings indicate that the addition of ODGV significantly improves the performance of cross-flow wind turbines.

Abstract

Shipping safety is a main priority in all industries, including the shipping industry. The shipping industry must provide guarantee of the safety of people and cargoes in the shipping process. Ensuring shipping safety will support increased world trade. The development of the shipping industry has increased due to world trade, but this increase is not consistent with shipping safety standards. Shipping safety is low due to the quantity of ship accidents that have caused fatality and property loss. Humans error are one of the factors causing ship accidents. Inadequate skill and competence of ship crew is one of the indicators in human error that can cause ship accidents. Inadequate skill and competence of ship crew due to limited time and space to learn and improve their skills and competency. Purpose of this study is to develop maritime learning application prototype, that can be used crews to learn by ship and improve their competence and skills with flexible time and place. The name is application is Smart Shipping. The method used in this research is the waterfall method. The result of this research is an e-learning Prototype that was designed based on user’s competence and subject expertise as well as the position on the ship. Material in this e-learning can be downloaded for offline learning. Furthermore, e-learning provides learning evaluation to measure user understanding through questions, exercises, and tests. The shipping industry can use this e-learning as a preventive action of ship accidents due to human error.

Abstract

Utilizing B30 as diesel fuel has the advantage of being heated to a specific temperature. Manually setting the temperature during the heating and fuel-filling process in the heating tank causes fuel performance to become less effective and efficient. This research aims to evaluate the capability of the prototype as a B30 fuel heater. The research method was carried out experimentally by testing variables for the temperature sensor (DS28B20), distance sensor (VL53LOX), heater control system, fuel filling system, and performance of the B30 diesel fuel heater prototype on a 7 HP single-cylinder diesel engine. The research results show that the fuel heater prototype can regulate the desired temperature and fill the heating tank automatically. The fuel temperature tested starts from 280C to 650C with an average multiple of 50C and tolerances of +20C and -10C. At the same time, it can automatically fill fuel from the main tank to the heating tank set from 800 ml to 1200 ml. B30 performance on a 7 HP single-cylinder diesel engine with 100 ml of fuel heated at 280C - 650C each shows the longest fuel consumption time at 350C and the fastest at 450C.

Abstract

Outrigger boats are prevalent in Indonesian waters. In Indonesia, the majority of Outrigger boats have a gross tonnage of less than 7 GT, resulting in their classification as "boats." After being hit by waves, the outrigger serves as a balancing mechanism on the boat, ensuring that it does not capsize and that it continues to keep its stability. In spite of the fact that they have a number of benefits, outrigger boats also have a number of drawbacks. One of these drawbacks is that they need a mooring space that is sufficiently large to anchor the boat at the beach or pier. This research was carried out through the use of experimental methodologies. The stability value is a reference to the design parameters established by IMO A.749 (18), which are applicable to all boats. Type 2 boats have a maximum GZ value that is greater than that of type 1 boats. According to the findings of the study, the utilization of the Palabuhanratu pool was increased by 33% on model B boats and by 52% on boat C when the outrigger boom was pulled while the boat was in the port pool. This was in comparison to the original value when the boat was anchored without pulling the outrigger boom.
