Abstract

Masyarakat Indonesia yang mata pencaharian sebagai nelayan, memerlukan kapal dan peralatan penangkap ikan yang cukup memadai.  Untuk itu perlu dilakukan pengembangan teknologi pada kapal penangkap ikan yang murah, kuat dan modern. Sehingga dikembangkan kapal penangkap ikan dengan kapsitas 30 GT dengan bahan fiberglass. Yang mana bahan fiberglass memiliki kemudahan dalam proses pembentukan lambung dan proses penyambungan bagian-bagian kapal penangkap ikan yang akan dikembangkan tersebut. Pada saat ini kapal fiberglass yang telah banyak dibuat atau dikembangkan di Indonesia memiliki banyak kekurangan, diantaranya kebocoran disambungan dan  mudah pecah akibat besarnya ombak yang menimpa. Akibat yang ditimbulkan oleh beban-beban yang bekerja tersebut, akan membentuk sebuah bending moment yang  harus mampu diterima oleh struktur kapal penangkap ikan 30 GT tersebut. Dimana modulus struktur kapal penangkap ikan 30 GT tersebut yang akan dirancang, harus memiliki tegangan yang terjadi mampu menahan akibat bending moment dan tidak boleh melebihi dari batas tegangan yang diijinkan. Selanjutnya didapatkan umur kelelahan kapal FRP tersebut, dihitung dari principle stress dari MEH untuk mendapatkan nilai SCF dan diplotkan kedalam kurva S-N. Maka didapatkan umur kekuatan kapal lebih dari 10 tahun. Hal ini dilihat dari hasil damage ratio juga menghasilkan nilai yang cukup baik. STRUCTURE ANALYSIS OF FATIGUE IN 30 GT FISHING VESSEL Indonesian society living as fishermen, need adequate fishing vessels and equipment. It is necessary for the development of the technology on board fishing vessels that are cheap, powerful and modern. Thus developed fishing vessels with capacities of 30 GT with fiberglass. Fiberglass material which has facilities in the process of forming the hull and the process of joining the parts of fishing vessels be developed. At this time of fiberglass boats that have been produced or developed in Indonesia has many deficiencies, including leakage in the join and easily broken due to the high waves. Consequences caused by the burdens of the work, will form a bending moment to be able to be accepted by the structure of the 30 GT fishing vessel. Where modulus structure of the 30 GT fishing vessel will be designed, it should able to withstand tension due to bending moment and shall not exceed the limit allowable tension. Subsequently obtained the fatigue life of the FRP vessels, calculated on the principle stress of MEH to get the value of SCF and plotted into the S-N curve. So we found the age of the ship strength more than 10 years. It is seen from the results of the damage ratio also produces a fairly good value.Keywords: Loading, Strength, Stress, Fatigue

Abstract

The economic condition of the coastal communities of East Java, especially in Banyuwangi, is strongly influenced by the tourism and fishing sectors. This condition needs to be developed with supporting facilities such as the procurement of fishing vessels. Procurement of fishing vessels must be designed with a feasibility study on vessel operations. In general, coastal conditions have shallow water depths and are often used by coastal communities for lobster cultivation. The supporting fishing vessels must be able to maneuver properly and not damage the ecosystem so that the existence of coral reefs is maintained. The fishing boats that support lobster aquaculture are designed with good maneuverability by taking into account the speed, the result of the waves formed and the capacity of the ship. The results of the design of fishing boats supporting lobster cultivation obtained that the main size of the ship is 13.00 meters long, 3.00 meters wide and 0.8 meters draft with a speed of 12 knots, reaching a designed mileage of 30 km in shallow water operational conditions

Abstract

In general, molding or FRP ship molds can only produce 1 (one) hull shape. This is of course, contrary to the production of ships which are mostly of the customize type (based on consumer demand) and very rarely in the form of mass products to produce sister ships. The high cost in the allocation of molding certainly makes economic considerations regarding the cost of shipbuilding. With the aim of a friendly fishing boat price, of course, it can make a mainstay and ease the burden on the answer to the high demand for fishing boats in the coastal community or the South Coast of Java. Multi-mold is a ship molding solution for FRP ship material that can produce more than one hull shape. This of course, will reduce the cost of producing a ship or boat. The cost budget plan is determined in detail through a survey of material prices and conducting a price determination study with an engineering estimate approach. In the multi-mold system or components, there are the main shell structure, reinforcement frame and suppot or mold holder. The shape of the multi-mold is carefully designed which can be knocked down each constituent component. The multi-mold disassembly process is accompanied by operational instructions and 3D simulation of the multi-mold assembly. The structural strength of the multi-mold components is also analyzed so that an effective and efficient multi-mold design is obtained

Abstract

The Remotely Operated Underwater Vehicle (ROV) has several inspection functions. One of them is the inspection function for hull damage. The damage that often occurs in the hull is corrosion. The corrosion can cause a decrease in the strength of the hull plate, reduce the speed of the ship, and decrease the quality of the safety level of ships and passengers. This study aims to classify the level of corrosion intensity on ship hulls by implementing a Convolutional Neural Network (CNN). Identification is carried out on images taken by underwater cameras via a Remotely Operated Vehicle (ROV). The intensity of the area affected by corrosion is identified so that the level of corrosion intensity can be classified and it can be considered that the ship needs maintenance to prevent even greater losses due to corrosion. The dataset used is 240 image data divided into 3 classification categories: low, medium, and high corrosion intensity. The accuracy of the real-time testing of the CNN method on the dataset plate when conditions outside the water reached 91.1% and on the dataset plate when conditions underwater reached 86.6%.

Abstract

The objective of this research is to design a catamaran tourist ship that incorporates green technology. To achieve this, the main dimensions of the ship will be determined using the linear regression method, based on existing data from similar vessels. The empirical data from existing vessels serves as the foundation for the analysis and prediction, thereby enabling the identification of relationships and patterns between the key variables, including length, width, draft, displacement, and passenger capacity. The linear regression method offers several advantages, including simplicity, ease of interpretation, and efficiency in the use of resources. As a result, it is an effective tool for initial analysis before the application of more complex methods. The R2 value has an average result above 90 percent, so the data can be considered good and valid. The innovative aspect of the design of this tourist ship is the utilisation of data pertaining to existing vessels that have demonstrated optimal performance in their role as tourist ships. The use of existing data not only helps reduce the risk of errors in the design of new vessels but also ensures that the design is efficient and compliant with operational needs and safety regulations. This research confirms the importance of a data-driven approach in the design of environmentally friendly and efficient ships. In the context of ship design and operation, displacement represents a pivotal parameter in linear regression analysis. An understanding of the relationship between displacement and ship performance allows for more accurate predictions regarding speed, fuel consumption, stability, and draft. This allows for the design of ships that are more efficient, stable, and safe, and optimized under a variety of operational conditions.
