Abstract

Transformation in ship geometry and the development of alternative materials to replace wood will certainly have an impact on the weight of construction, these changes will certainly affect the center of gravity and ship draft, such as wooden ships with steel frames which are made by wooden ship craftsmen in Takalar Regency, after being replaced with steel frame, laden increases with an increase in the draft will affect the hydrostatic characteristics of the ship and the ship's center of gravity, the change, of course, has an impact on the stability of the ship, so an inclining test is needed, so that wooden ship craftsmen can understand the relationship between ship geometry and ship weight. Therefore, in an effort to increase the knowledge of wooden ship craftsmen, inclining test training is a solution and is proposed for community service activities with method of presenting material and practicing directly on ships, the results of this training craftsmen are able to understand the emphasis on steel-constructed wooden ships in relation to life safety at sea and skilled in inclining to test.

Abstract

As the main material, wood is required in the process of wooden ships building. The required wood must be water resistant especially for the construction of the ship wooden plank as well as wood in intact form for use on the keel of the ship to support the ship frames. It is increasingly difficult to obtain the required wood for the keel construction need since the requirements for the integrity of the keel construction which must continue throughout the ship. This condition threatens the sustainability of the wooden ship construction process in Indonesia. Hence, material alternative is urgently required for wood substitution for the ship keel. A study has been conducted with a recommendation of a steel keel (dimensions and shape of the keel) as a substitute for a wooden keel for certain ship dimensions. Socialization of this new technology needs to be done to wooden ship craftsmen in South Sulawesi in particular. The partners chosen in this activity were the member of the wooden boat craftsman group "Torani" in Galesong Kota District, Takalar Regency. The aim is to introduce steel material as a substitute for wood material in the wooden ship keel construction to overcome the difficulty of obtaining wood for the ship keel construction. The result shows that the majority of participants claim to have new knowledge and believe that it is possible to apply the technology to wooden ship construction. However, since the manufacture and installation of steel keels on wooden ships uses steel materials, the application of this technology will take a relatively longer time.

Abstract

The ship's resistance is important to know because correlates strongly to the power engine needs to reach the desired speed. One method can be applied on a small ship with full-scale free running within a ways pull small ship with other small ship for measure resistance value occurrence with scale equipment on the place between the ropes of the ship being towed and tugged. This method is very easy to apply to small ships. In general, manufacturers of traditional small ships do not carry out the full-scale test because they do not know the principles for determining engine power.

Abstract

Biofouling, the accumulation of marine organisms on ship hulls, poses a substantial challenge in the maritime industry. Over time, organisms like algae and molluscs adhere to hull surfaces, creating a biofouling layer that disrupts water flow and increases ship resistance. This study investigates the effects of biofouling on ship resistance and fluid flow patterns along the hull. Data collection involved measuring key ship dimensions, analyzing ship lines plan drawings, and measuring biofouling thickness. Autodesk Computational Fluid Dynamics (CFD) software was used to calculate ship resistance and analyze fluid flow along the hull. Two conditions were compared: a hull without biofouling and a biofouled hull. At a speed of 1.220 m/s, the biofouled ship model exhibited a resistance of 3,739 N, while the clean hull had a resistance of 3,280 N, indicating a 13.642% resistance increase due to biofouling. Fluid flow analysis revealed complex flow patterns along the biofouled hull, potentially reducing operational efficiency. These findings underscore the importance of biofouling prevention and control measures in minimizing resistance and maintaining operational efficiency. A deeper understanding of fluid flow characteristics related to biofouling allows ship operators and companies to make informed decisions about vessel maintenance, reducing environmental impacts and operational costs. This research contributes to addressing biofouling challenges in the maritime industry.

Abstract

One of the centers for traditional wooden boat construction in South Sulawesi is Galesong District, Takalar Regency, South Sulawesi. Generally, wooden boats constructed by craftsmen in this area are for fishing. Craftsmen's skills in building the boat were acquired from their predecessors. However, the craftsmen still faced some problems during the boat construction work. One of the problems is related to launching the boat into the water, which is still conducted traditionally using logs and sandbags. The solution is to propose the use of airbags to launch ships. Airbags have been used to launch steel ships but relatively not for wooden boats. Hence, this activity aims to introduce the use of airbags to launch the boat. The target for the introduction is a group of wooden boat craftsmen, "Patorani," in Galesong District, Takalar Regency. Before and after the activity, achievements are evaluated by identifying the perceptions and views of craftsmen regarding the airbags. The activity is conducted through socialization and explanations of airbags with visualization. The result shows that almost 90% of the craftsmen had never heard of airbags before and were unsure that airbags could be used to launch the boat. However, after the activity, most craftsmen can be convinced that airbags can solve their boat launching problems. Only one participant out of 15 still had doubts about the use of airbags for boat launching. The rest of the participants were even ready to use the airbags to launch their boats.

Abstract

The construction of wooden boats for fishermen in South Sulawesi is starting to find it difficult to get high-quality wood, especially for boat hulls. An alternative to wood as a wooden ship hull is steel. The problem of joining or fastening planking boards made of wood with a steel frame is not fully understood by the wooden boat craftsmen in Galesong. For this reason, this activity aims to socialize the binding of planking boards with wooden ship steel frames to the "Patorani" craftsman group in Galesong District, Takalar Regency. The activity was carried out using the lecture method (socialization) and a simple demonstration using a wooden ship model. The results of the activity showed that the members of the craftsman group were very enthusiastic about participating in the activity and hoped that steel could replace wood as a ship construction material. Prior to the activity, almost none of the craftsmen group members had seen and knew that steel could be used as a ship's hull, and at the end of the socialization, they believed that steel could be a substitute for wood as a wooden ship's hull so that the construction and production of wooden ships would continue. Furthermore, it is also seen that members of the craftsman group can understand the technique of installing or fastening planking boards to steel frames.
