On the previous research, the foil shaped has been proposed to improve the drag force characteristics of the conventional zinc anode as sacrificial cathodic protection. As a part of the previous research efforts, the aim of this research is to evaluate the hydrodynamics characteristics of fin shaped geometry for sacrificial anode body to reduce the...

Regulations from the International Maritime Organization (IMO) regarding energy efficiency mean that the ship design must have the least possible resistance so that fuel consumption is also low. Several modifications to the shape of the hull have been developed so that the performance of the ship can be improved so that its use is more efficient. T...

Bamboo is a material that can grow quickly, cheap and widely available. Its material properties are lightweight but harder and stronger than wood or glass fibre composites. The purpose of this study was to determine the effect of the direction arrangement of petung bamboo blades on the interface of the laminated bamboo fibre matrix. The benefits of...

Indonesia memiliki sumberdaya alam terutama sumberdaya perikanan yang melimpah, namun pada kenyataannya sumberdaya perikanan tersebut masih belum mampu untuk dipetakan sehingga para nelayan masih kesulitan untuk menemukan daerah penangkapan ikan. Penulis membuat prototipe Findev (Fish Finder and Visual Imaging Remote Underwater Vehicle) yaitu sebua...

Bamboo is an extraordinary natural material. Bamboo can grow quickly, is cheap and widely available. The material property is light but harder and stronger than wood or glass fiber composites. The purpose of this study was to determine the effect ofarrangement and size of petung bamboo split fiber to the matrix interface bond of laminated bamboo sp...

Fishing boat in Indonesia generally use wood materials. In its development, PVC pipe alternative material can be used as hull. Ship accidents in Indonesia are much due to the turning of boats (capsizing) related to the rolling movements of boats. This research aims to know the fish liner made of PVC pipes with a variation of the hull shape has floo...

This study have been done to investigate the characteristics of the fishing boat using PVC pipe material with variations of hullform that have the smallest total ship resistance, and good ship stability that meets International Maritime Organisation (IMO) standards. The method used in this study is to creating 3D modeling with variations of hullfor...

Bamboo can be used as an alternative material because of inexpensive and good mechanical properties. The study aims to obtain the maximum tensile strength and compressive strength of laminated bamboo and Wood Class category according to BKI, using horizontal and brick blade arrangement. Tensile strength test was based on SNI 03-3399-1994 standard a...

The use of PVC materials as an alternative material for fishing boat is being developed in Pekalongan, Central Java, Indonesia. Therefore, further analysis is needed to assist this development. In this paper, the analysis of ship stability of PVC fishing boat is investigated and be compared with wooden traditional fishing boat. The results of this...

AbstrakKapal selam merupakan kapal yang mampu beroperasi dibawah air dengan mandiri, namun juga harus bergerak senyap dibawah air tanpa terdeteksi. Maka dari itu salah satu kebutuhan paling penting dalam kapal selam adalah Baling-Baling atau Propeller. Baling-baling kapal selam membutuhkan beberapa kriteria khusus yaitu baling-baling kapal yang dap...

Analisis seakeeping (kemampuan olah gerak kapal) merupakan aspek penting dalam perancangan kapal. Berdasarkan analisis tersebut, dapat diketahui batas operasional dari sebuah kapal. Salah satunya adalah dapat mengetahui kemampuan kapal pada tinggi gelombang signifikan (Hs) tertentu. Memodifikasi bentuk haluan kapal dengan membuat dasar dari haluan...

Prediksi performa seakeeping (olah gerak) kapal di perairan tertentu adalah salah satu dari aspek-aspek penting pada tahap perencanaan kapal. Penelitian ini fokus pada optimasi bentuk demihull kapal untuk meningkatkan kualitias seakeeping sesuai dengan standar kriteria umum seakeeping untuk kapal militer. Bentuk lambung demihull yang digunakan adal...
