Abstract

This paper discusses the prediction of ship stability before sailing. This study aims to determine the stability value of the water ambulance in specific operating scenarios. The method used in this study is the B-splines mathematical equation and the optimization method using Maxurf software, which varies ship loading by 100% DWT, 50% DWT, and 25% DWT. The results of the study showed that 100% DWT had a maximum GZ value of 40 degrees and an initial GM of 1.240 meters; 50% DWT conditions had a maximum GZ value of 41.8 degrees and an initial GM of 0.711 meters; and 25% DWT conditions had a maximum GZ value of 43.2 degrees and an initial GM of 0.653 meters. The initial GM value increases with an increasing DWT value. Meanwhile, the maximum GZ value decreased as the DWT value increased. All operational scenarios are determined to meet HSC 2000 Annex 8 monohull criteria.

Abstract

The scarcity of materials due to the impact of the pandemic has caused the price of shipbuilding materials is increased and the production costs to become more expensive. So, optimization steps need to be taken to reduce production costs but still ensure the quality of the coal carrier pontoons. One of the optimization steps that can be done is by changing the frame distance. In this study, two variations of the frame distance, 600 and 650 mm, will be carried out to obtain the optimal value from the initial design of 610 mm. In the numerical calculation, each construction model will be analyzed for the magnitude of the stress using finite element method software in still water conditions, sagging, and hogging. From the calculation results, the profile size of the frame distance of 600 mm is smaller than the frame distance of 650 mm; this happens because the modulus value is smaller. In the stress analysis, the highest allowable stress value was obtained from the sagging condition at a frame distance of 610 mm with a value of 84.87 MPa.

Abstract

Sail boat is a type of sail boat with the main mover in the form of a sail that utilizes the wind to generate thrust so that it can go according to the desired speed. Although the type of sail propulsion has been found since time immemorial, research on sails and their effects on sailboats is very rarely done. In general, research only focuses on calculating the size of the sail so that the sailboat is able to go at the desired speed without considering other things that might happen to the sailboat if the sail is used. Therefore, the researcher intends to analyze the force on the sail with variations of the sail and ring and its effect on the sailboat. Based on the results of the research conducted, taking into account the wind conditions in the coastal area of ​​Banyuwangi, the results of the data analysis are as follows, including the size of the main sailing vessel that is suitable for having a length of 5 meters, a width of 2 meters and a height of 1 meter and a water laden depth of 0 ,5 meters. The best wind direction is at 180° or behind the sail boat. The optimum wind speed that can be used is 30 knots or 15 m/s. And the maximum heeling degree that can be tolerated before the sail boat is 25° Direction of port side and right.

Abstract

Kapal Selam Mini 29 Meter dengan diameter hull 3 meter dan displacement 130 T sangat cocok untuk perairan Indonesia Barat yang dangkal karena memiliki beberapa kelebihan. Perhitungan powering terutama tahanan kapal dilakukan dengan menggunakan metode MIT dan metode kapal pembanding untuk mendapatkan koefisien Admiral. Berdasar dari hasil perhitungan kedua metode tersebut dilakukan perancangan propeller. Propeller didesain dengan menggunakan Propeller B-series. Penggunaan propeller B-series lebih disebabkan karena kelengkapan data dan informasi performa seri tersebut bila dibandingkan dengan seri propeller lainnya. Dari analisa kebutuhan thrust dan ketersediaan daya mesin, maka propeller B5-60 ternyata layak dipakai sebagai propulsor Kapal Selam Mini 29 Meter.

Abstract

3D Printing is becoming a more reliable and professional manufacturing method. The benefits of additive manufacturing such as design optimization, weight reduction, and ease of prototyping are factors that speed up the 3D printing process. Although further research on 3D printing is still needed, in some specific applications, 3D printing can be useful. The maritime industry still uses conventional technology in shipbuilding. In addition, shipbuilding has to face very high classification requirements that compel the use of technology that ensures repeatability and high quality. The factor of the length of the process is due to difficulties in the raw materials for shipbuilding. Fiberglass is an alternative basic material for shipbuilding with sufficient material availability, relatively cheap prices, light weight, and more flexibility in catching fish. Fiberglass boats have a longer service life, corrosion resistant, light weight, low production and maintenance costs, and effectively increase fishing. The difficulty of the conventional method of hand lay-up and vacuum infusion in the construction of fiberglass boats is due to the difficulty of determining the composition of the material, as well as the emergence of air bubbles which causes a decrease in the strength of the ship. So the chopper gun method is an efficient method. This research provides information about current R&D in the field of 3D Printing application in shipbuilding, especially ships made of Fiberglass, possible benefits, methods, materials, and opportunities.

Abstract

The Indonesian Ocean Energy Association has ratified the potential for ocean wave energy in Indonesia with a theoretical possibility of 141.472 x 109 watts. Unfortunately, this vast potential has not yet been utilized optimally in the Indonesian seas. Ocean wave energy technology has developed rapidly in various countries worldwide. The Oscillating Water Column (OWC), which uses the oscillating movement of ocean waves' airflow, is one of the most well-known systems for generating power from waves. A novel model of ocean wave power generation was created with the use of a more basic fan turbine and inspiration from OWC. It is directly integrated with an electric dynamo and an internal flow system in a venturi tube, which can increase airspeed based on continuity theory. The experiment's results succeeded in creating up and down movements of ocean waves with a high tide of 15 cm and a low tide of 12 cm. Ocean wave oscillations can produce gusts of air with a speed of 1.56 m/s. The final result is obtained by model performance with an average turbine rotation speed of 42.191 rpm, an average electric voltage of 0.809 volts, and a more optimal turbine efficiency of 67.9%.

Abstract

In previous studies by Saputra, the use of straight Hull Vane® increased ship's resistance. Based on hypothesis, this was caused by lifting force from Hull Vane® being too large, so that ship experienced bow trim. To reduce bow trim, smaller Hull Vane® was made including Hull Vane® with AR = 8.5, AR = 22.9 and AR = 28.94 with speeds which were 11 knots (Fn = 0.34), 17 knots (Fn = 0.53), 20 knots (Fn = 0.62) and 26 knots (Fn = 0.8). From simulation results, it was found that use of a straight Hull Vane® in every aspect ratio variation on vessel was only effective at 11 knots speed which could reduce ship's resistance up to 17%. For speeds above 11 knots, increased in aspect ratio can reduce resistance but resistance on ships with straight Hull Vane® was still greater than on ships without Hull Vane® because lift force by Hull Vane® at ship stern was still too large, so the bow of ship was more submerged than ship without Hull Vane®. This caused value of the wetted surface area (WSA) and value of hydrodynamic pressure more increased than ships without Hull Vane®, so value of ship's resistance also increased.

Abstract

Material fiberglass masih menjadi alternatif dalam pembuatan kapal di Indonesia, hal ini terlihat dari banyaknya kapal ikan berbahan fiberglass pesanan KKP pada tahun 2016. Penelitian ini bertujuan untuk melakukan tinjauan sejauh mana penerapan aturan klasifikasi pada proses produksi pembangunan kapal ikan 3 GT dengan melakukan pengujian kuat tarik dan kuat tekuk terhadap spesimen laminasi kapal ikan FRP 3 GT yang diambil dari dua galangan yang sedang membangun kapal ikan pesanan Kementerian Kelautan dan Perikanan (KKP) tahun 2016, dimana proses pembangunannya mengacu pada persyaratan pengujian dalam Biro Klasikasi Indonesia (BKI) tahun 2015, yang memakai International Standard (ISO) 527-4 (1997) untuk uji tarik, dan ISO 14125 (1998) untuk uji bending. Spesimen yang akan diuji masing-masing diambil dari bagian lunas (keel), alas (bottom) dan sisi (side). Secara keseluruhan hasil yang diperoleh dalam penelitian ini adalah mengevaluasi dari laminasi struktur konstruksi yang pada penerapannya tidak memenuhi dari aturan klasifikasi dan juga memberikan alternatif susunan laminasi optimal untuk diterapkan dalam pembangunan kapal ikan 3 GT berbahan fiberglass. Penelitian ini juga nantinya dapat berkontribusi dalam penyusunan standarisasi untuk kapal-kapal fiber berukuran kecil.
