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.

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.

Abstract The ship safety domain plays a significant role in collision risk assessment. However, few studies take the practical considerations of implementing this method in the vicinity of bridge-waters into account. Therefore, historical automatic identification system data is utilised to construct and analyse ship domains considering ship–ship and ship–bridge collisions. A method for determining the closest boundary is proposed, and the boundary of the ship domain is fitted by the least squares method. The ship domains near bridge-waters are constructed as ellipse models, the characteristics of which are discussed. Novel fuzzy quaternion ship domain models are established respectively for inland ships and bridge piers, which would assist in the construction of a risk quantification model and the calculation of a grid ship collision index. A case study is carried out on the multi-bridge waterway of the Yangtze River in Wuhan, China. The results show that the size of the ship domain is highly correlated with the ship's speed and length, and analysis of collision risk can reflect the real situation near bridge-waters, which is helpful to demonstrate the application of the ship domain in quantifying the collision risk and to characterise the collision risk distribution near bridge-waters.
