Disain Sistem Automatic Identification System (AIS) Berbasis Mini PC
'P3M - Politeknik Perkapalan Negeri Surabaya', 2019Co-Authors: Maulidi Akh.Abstract:Automatic Identification System (AIS) merupakan suatu sistem pelacakan otomatis pada kapal dan Vessel Traffic Services (VTS) untuk mengidentifikasi serta menemukan kapal dengan mekanisme pertukaran data secara elektronik dengan kapal lain yang berdekatan dan stasiun VTS. Informasi yang disediakan oleh peralatan AIS, seperti identitas kapal, posisi, jarak, dan kecepatan. International Maritime Organitation (IMO) dan Konvensi Internasional untuk Keselamatan Jiwa di Laut (SOLAS) 1974 dan Colreg (collison regulation 1972) mewajibkan AIS untuk dipasang dikapal yang mempunyai Gross Tonnage (GT) 300 ton atau lebih dan juga untuk semua jenis kapal penumpang. Dengan demikian AIS memiliki fungsi stategis dalam sistem navigasi kelautan, akan tetapi dengan harganya yang tinggi tidak dapat dijangkau nelayan tradisional. Dari hal tersebut, penulis mencari alternatif yang dapat menjadi solusi untuk mendapatkan sistem navigasi yang murah dan handal. Mini Computer (mini PC) merupakan sebuah komputer mini yang dibuat untuk dapat melakukan berbagai hal seperti komputer pada umumnya. Dengan komponen pin General Purpose Input Output (GPIO), Mini PC dapat difungsikan untuk mengendalikan berbagai perangkat elektronik. Dengan memberikan instruksi (algoritma program) pada mini PC untuk mengirimkan dan menerima ordinat, kecepatan, dan arah pergerakan kapal.

'Politeknik Negeri Bengkalis', 2019Co-Authors: Maulidi Akh.Abstract:Automatic Identification System (AIS) merupakan sistem navigasi yang digunakan pada Vessel Traffic Services (VTS) untuk mengidentifikasi dan bertukar data secara elektronik. Organisasi Maritim Internasional (IMO) dan Konvensi Internasional untuk Keselamatan Jiwa di Laut (SOLAS) 1974 dan Colreg (collision regulation 1972) mewajibkan AIS untuk dipasang dikapal yang mempunyai Gross Tonnage (GT) 300 ton atau lebih dan juga untuk semua jenis kapal penumpang.AIS dapat menggantikan beberapa alat komunikasi lain yang selama ini digunakan seperti kompas, peta, radar maupun GPS. Akan tetapi fungsi dan kepraktisan yang dimiliki sebanding dengan harganya yang sangat mahal sehingga nelayan tradisional tidak dapat menjangkau harganya yang relative mahal. Dari hal tersebut, peneliti mencari alternatif lain yang dapat menjadi solusi untuk mendapatkan system navigasi yang murah dan handal.Pada Mini PC terdapat pin General Purpose Input Output (GPIO) yang dapat difungsikan sebagai penerima atau pemancar sistem navigasi. Selain itu mini PC memiliki harga yang sangat murah dibandingkan dengan perangkat sejenis. Dengan memberikan algoritma program pada mini PC dapat difungsikan sebagai AIS Pemancar (Tranceiver) untuk mengirimkan data ordinat, kecepatan, dan arah pergerakan kapal. Serta sebagai penerima (Receiver) untuk menerima data ordinat, kecepatan, dan arah pergerakan kapal. Dengan demikian AIS Mini PC dapat menjadi solusi alternatif dan membantu kapal nelayan tradisional di Madura dalam memperoleh sistem navigasi

Disain Sistem Navigasi Automatic Identification System (AIS) Transceiver Berbasis Mini Computer Pada Kapal Nelayan Tradisional Di Madura
'Politeknik Negeri Bengkalis', 2019Co-Authors: Maulidi Akh.Abstract:Navigation system is the key of ship safety in sailing. Automatic Identification System (AIS) is a navigation system used in Vessel Traffic Services (VTS) to identify and exchange data electronically. The International Maritime Organization (IMO) and the 1974 International Convention for the Safety of Life on the Sea (SOLAS) and Colreg (1972 collision regulation) require AIS to be installed in ships that have a Gross Tonnage (GT) of 300 tons or more and for all types of passenger vessels.AIS can replace a number of other communication tools that have been used such as compass, maps, radar and GPS. However, the function and practicality that is owned is comparable to the very expensive price so that traditional fishermen cannot reach the expensive price. From this, researchers are looking for other alternatives that can be a solution to get a cheap and reliable navigation system.By General Purpose Output Input (GPIO) pin on Mini PC, it can receive Input and expend output based on instructions given directly or using Web Server. Besides, mini PC has very cheap price compared to similar devices. By providing algorithm program on a mini PC, it can be used as an AIS Transceiver to send ordinate, speed, and direction of ship movement ship. Thus, help traditional fishing boats in Madura to obtain their navigation system

relationship between the boat sizes tight source output for fishing lamps and the catch of squid todarodes pacificus steenstrup in coastal squid jigging fishery of japan
Korean Journal of Fisheries and Aquatic Sciences, 2002Co-Authors: Choi Sok JinAbstract:Sizes of coastal squid jogging boats, their light source output for fishing lamps and daily catch data were collected, for a purpose of evaluating factors on fishing boats, which affect to the squid catch, from four fishing ports (Hakodate, Sado Island, Noto and Tsushima) in Japan. The catch amount was increased as boat sizes and their light source output of fishing lamps were increased up to 100200 kW class and 1115 Gross Tonnage class. The relationship between catch per unit efforts y (box/machine/day), Gross Tonnage x_{1}, (GT) and light source output for fishing lamps x_2 (kW) is expressed as following formula; $y

Thunder Bay National Marine Sanctuary (TBNMS) Shipwreck: Monohansett
ScholarWorks@GVSU, 2015Co-Authors: Parsell Tim, Alpena Community College, Grand Valley State UniversityAbstract:The following on the shipwreck Monohansett is from the NOAA website for Thunder Bay Sanctuary. GPS Location: N45° 01.996’ W83° 11.988’ Depth: 18 Feet Wreck Length: 160 Feet Beam: 30 Feet Gross Tonnage: 572 Cargo: Coal Launched: 1872 by Linn and Craig at Gibraltar, Michigan Wrecked: November 23, 1907 Description: Built as the double-decked bulk freighter Ira H. Owen, the ship was rechristened Monohansett in 1882. Ten years later, it was rebuilt as a single-decked lumber carrier. On November 23, 1907, the ship burned to the water\u27s edge at Thunder Bay Island. Most of the crew lost their personal belongings and some suffered minor burns, but there was no loss of life because the ship was near the island’s Life Saving Station. Today, the Monohansett’s wreck lies in three sections. The stern portion has hull features, propeller, and shaft all in place, and the boiler is nearby

catch performance of coastal squid jigging boats using led panels in combination with metal halide lamps
Fisheries Research, 2012Co-Authors: Yukiko Yamashita, Yoshiki Matsushita, Toru AzunoAbstract:Abstract Squid attracting light systems consisting of low power light emitting diode panels (LEDs) and conventional metal halide lamps (MHs) were tested to describe the influence of combinations of LEDs and MHs on squid catch. Fishing trials using LEDs (9 kW) and different numbers of MHs were carried out in August and September 2009 targeting two squid species: (1) Japanese common squid Todarodes pacificus in northern waters of the Sea of Japan (off Hokkaido) by 4 coastal squid jigging boats (19 Gross Tonnage) and (2) swordtip squid Photololigo edulis in western waters (off Iki) by 5 boats of the same class. Catches of both species tended to increase with the number of MHs. Generalized Linear Model analysis revealed that in addition to the number of MHs, the catch amount was influenced by fishing power (ability) of boat and by the monthly variation of squid abundance (only for P. edulis off Iki). The expected catch (number of boxes) was not proportional to the number of MHs. The largest catch was expected for P. edulis off Iki by using LEDs with 24 MHs. The optimal combination of LEDs and MHs for T. pacificus off Hokkaido was less clear because the combination with 36 MHs had the largest positive effect on the catch; this was the maximum number MHs used.
