On the Great Trimaran-Catamaran Debate
On the Great Trimaran-Catamaran Debate Lawrence J. Doctors, Member, School of MechanicnJ and Manufacturing Engineering, The University of New South Wales, Sydney, NSW 2052, Australia Abdmct In the cumwtt work, a aydewaatic investigation into a variety of monohulls and mul- tihulls is carried out with an emphasis on finding optimal forms. Vessels with up to six identical subhulls are taken into consideration and a large range of lengths is studied. hT- thermore, sidehuli trimaran configurations are included in the investigation. There are two main purposes to this investigation. Firstly, one is interested in mini- mizing the wave resistance, becawe this is closely related to the wave generation and is of critical importance to the operation of river ferries. Secondly, it is also important to min- imize the total resistance, in order to reduce fuei costs and to permit long-range trips for ocean-going vessels. The theoretical predictions show that increasing the length beyond that normally accepted is beneficial in reducing both the wave Resistance and often the total resistance. I. the goal is to minimize wave resistance and if the length is constrained, the calculations also demon- strate that trimarans are superior to catamarans, which are in turn superior to monohulls. On the other hand, if the goal is to minimize the total resistance, then all the muh!ihulis (~m catamarans to hezamarans) are inferior to monohulls, except possibly at low speeds which are not of interest in thw study. Similarly, sidehull trimarans are shown to be inferior to catamarans except perhaps if rather great lengths are permitted. -
25 Upaya Mengoptimalkan Implementasi Aplikasi
UPAYA MENGOPTIMALKAN IMPLEMENTASI APLIKASI INAPORTNET Eko Nur Hidayat1) 1 Program studi Teknika, Politeknik Bumi Akpelni Jl. Pawiyatan Luhur II/17, Bendan Dhuwur, Semarang. *Email: [email protected] Abstrak Era revolusi industri 4.0 ditandai dengan perpaduan teknologi yang mengaburkan batas antara bidang fisik,digital dan biologis, atau secara kolektif yang ditandai dengan munculnya terobosan menghubungkan perangkat apapun satu sama lain melalui internet (Internet of Things). Konsep tersebut juga diterapkan dalam pelayanan public di pelabuhan dengan system inaportnet. Masalah yang terjadi adalah pengguna sering mengalami loss connection sehingga pelayanan dilakukan melalui system manual. Penelitian ini menggunakan metode descriptive. Untuk menjamin konektivitas dari pengguna system dengan server, diperlukan konektivitas yang stabil dan mempunyai Service Level Agreement (SLA) yang tinggi. Konektivitas yang perlu dijaga baik dari sisi server maupun dari sisi pengguna. Sistem inaportnet akan berjalan optimal jika dari sisi server system selalu up dan terjamin konektivitasnyadengan kategori minimal tier 3 sedang dari sisi pengguna terjamin konektivitasnya dengan SLA diatas 99%. Optimalisasi dilakukan di kedua sisi baik server maupun pengguna. Hasilnya dengan optimalisasi implementasi inaportnet dapat meminimalisasi keluhan system down sehingga pelayanan kapal dan monitoring pergerakan kapal dan barang (petikemas) ekspor dan impor dapat dioptimalkan. Kata kunci: inaportnet, loss connection, servive level agreement, tier PENDAHULUAN depan, dan bertahan didalamnya,menjadi Revolusi industri 4.0 adalah era industri individu canggih dalam mengelola dan keempat sejak revolusi industri pertama memanfaatkan data, serta mampu bertahan pada abad ke-18. Era revolusi industri 4.0 dengan kecerdasan buatan akan membuat ditandai dengan perpaduan teknologi yang individu survive melewati revolusi industri mengaburkan batas antara bidang 4.0. -

5 Must Read Sailing Books for Catamaran Enthusiasts
5 Must Read Sailing Books for Catamaran Enthusiasts This list briefly discusses 5 books that yacht owners or enthusiasts should read. What makes each book unique? Why should they read the book? What will they learn or take away from it? This is - at least what we consider - the best 5 books ever written in English on the subject of cruising catamarans. There are a few German and French publications but they are nearly impossible to get , most are out of print and unless you can read German or French - are of no value. So here is the top 5 list of the "Must Read books for Catamaran Enthusiasts" 1.) CATAMARANS - THE COMPLETE GUIDE FOR CRUISING SAILORS, by Gregor Tarjan. First published in 2006 and reprinted in 2008 by Mc Graw Hill Companies, New York. ISBN 9780071498852. Hardcover, 305 pages full color, large format, illustrated and lavish photography by Gilles Martin Raget. Of course we have to mention this book first. Not only is it written by our own Gregor Tarjan, founder and owner of Aeroyacht Ltd., but it is hailed as "the industry reference" by many experts. It has sold many thousands of copies around the world and has been re-printed numerous times. Jim Brown calls it "an authoritative guide for novices and experienced sailors, the best book written on the subject since the early 1990's" 2.) MULTIHULL SEAMANSHIP - Illustrated, by Dr. Gavin LeSueur. Illustrations by Nigel Allison. First published in Australia in 1995, Cyclone Publishers. ISBN 1875181032. Soft cover, spiral bound, large format, 108 pages, black and white. -

A Comparative Evaluation of a Hydrofoil-Assisted Trimaran
COMPARATIVE EVALUATION OF A A HYDROFOIL-ASSISTED TRIMARAN Thesis presented in partial fulfillment of the requirements for the degree MASTER OF SCIENCE IN ENGINEERING By Ryno Moolman Supervisor Prof. T.M. Harms Department of Mechanical Engineering University of Stellenbosch Co-supervisor Dr. G. Migeotte CAE Marine December 2005 Declaration I, the undersigned, declare that the work contained in this thesis is my own original work and has not previously, in its entirety or in part, been submitted at any University for a degree. Signature of Candidate Date i Abstract This work is concerned with the design and hydrodynamic aspects of a hydrofoil-assisted trimaran. A design and configuration of a trimaran is evaluated and the performance of a hydrofoil-assisted trimaran is effectively compared to the performance of a hydrofoil-assisted catamaran with similar overall displacement and same speed. The performance of the trimaran with different outrigger clearances are also evaluated and compared. The hydrodynamic aspects focuses mainly on the performance and to a lesser extend on the sea-keeping and stability of a hydrofoil-assisted trimaran. The results were determined by means of experimental testing, theoretical analysis and numerical analysis. The project was initiated as a result of the success of the hydrofoil-assisted catamarans and due to the fact that there does not exist a hydrofoil-assisted trimaran (to the author’s knowledge) where the main focus of the foils is to significantly reduce the resistance. A brief history, recent developments and associated advantages regarding trimarans are discussed. A complete theoretical model is presented to evaluate the lift and drag of the hydrofoils, as well as, the resistance of the trimaran. -

Kapal Dan Perahu Dalam Hikayat Raja Banjar: Kajian Semantik (Ships and Boats in the Story of King Banjar: Semantic Studies)
Borneo Research Journal, Volume 5, December 2011, 187-200 KAPAL DAN PERAHU DALAM HIKAYAT RAJA BANJAR: KAJIAN SEMANTIK (SHIPS AND BOATS IN THE STORY OF KING BANJAR: SEMANTIC STUDIES) M. Rafiek Program Studi Pendidikan Bahasa dan Sastra Indonesia, Fakultas Keguruan dan Ilmu Pendidikan, Universitas Lambung Mangkurat, Banjarmasin, Indonesia ([email protected]) Abstract Ships and boats are water transportation has long been used by the public. Ships and boats also fabled existence in classical Malay texts. Many types of ships and boats were told in classical Malay texts are mainly in the Story of King Banjar. This study aimed to describe and explain the ships and boats in the Story of King Banjar with semantic study. The theory used in this research is the theory of change in the region meaning of Ullmann. This paper will discuss the discovery of the types of ships and boats in the text of the King saga Banjar, the ketch, ship, selup, konting, pencalang, galleon, pelang, top, boat, canoe, frigate, galley, gurab, galiot, pilau, sum, junk, malangbang, barge, talamba, lambu, benawa, gusu boat or bergiwas awning, talangkasan boat and benawa gurap. In addition, it was also discovered that the word ship has a broader meaning than the words of other vessel types. Keywords: ship, boat, the story of king banjar & meaning Pendahuluan Hikayat Raja Banjar atau lebih dikenal dengan Hikayat Banjar merupakan karya sastra sejarah yang berasal dari Kalimantan Selatan. Hikayat Raja Banjar menjadi sangat dikenal di dunia karena sudah diteliti oleh dua orang pakar dari Belanda, yaitu Cense (1928) dan Ras (1968) menjadi disertasi. -
