Selection Of

Today's methods of plotting courses and selecting sailing routes and turn points in maritime navigation are still largely based on subjective assessment of the master or the officer in charge. This results in a great variety of course distribution and, accordingly, in various ship movements. Modern electronic aids, in particular ECDIS (Electronic Chart Display and Information System) can significantly facilitate maritime voyage planning, course plotting, selection of turning points, etc. In addition to displaying electronic charts, the specific feature of these systems is that they facilitate route planning, supervision of ship movements, data recording, database search, alarm setting, etc. However, these systems do not yet provide automatic selection of courses on user's request in a standardised form. Therefore, in most cases, the routes and turn points are selected empirically or because they have been previously defined and used. This paper shows the drawbacks of the existing methods of selecting routes and plotting courses in maritime navigation and gives recommendations how to improve them.

Taking Action

In this paper, authors suggest an improvement in the electronic chart display and information system handling. Electronic nautical charts provide significant benefits to maritime navigation as a real time navigation system and all updates are important. This paper analyses the electronic chart use experiences on board ships. A questionnaire and survey were used so as to ascertain and corroborate the existing problems with corrections and maintenance of electronic charts on ships, and reliability of the systems was calculated. The survey results have shown that ship’s officers had serious problems with ECDIS systems which were difficult to solve during ship’s operation. A survey was done which showed that a significant percentage of the surveyed bridge officers and captains had problems with ECDIS system operation, such as operation stoppage due to different reasons. They did not always report failures of these systems while having continued to operate ECDIS. The reliability of those systems was also calculated and it resulted 0.916 or 91.6%. Compared to results of previous similar researches done by other scientists, the results of this research show an improvement in the ECDIS handling. It was concluded that a proper action was needed toward finding the solution to the future chart corrections procedure through remote monitoring and maintenance. The study results emphasized that taking action was necessary in the interest of safety protection on ships, with particular attention to be paid to better safety of navigation, of life, and of potential environmental pollution due to this type of information system failures. The results obtained by this study represent a good starting point for future researches in the field.

Maritime Navigation

Enhancements in shipboard automation offer the prospect of crew size reductions for navigation tasks. This work was concerned with comparing the structure of navigation tasks using paper charts with the same tasks accomplished using an electronic chart display information system (ECDIS). Voyage planning with paper charts is based on drawing specific voyage segments, measuring distances between waypoints, and annotating the chart with voyage specific information. These tasks change substantially with electronic charts, particularly in terms of how the task is accomplished. Similarly, the manual activities of track keeping are reduced, but the need for a continuous record maintains the use of the paper chart. For both navigation tasks, there is less ability to visualize geographic features continuously with electronic charts because of the keyhole effect created by a CRT display. It is concluded that the design of automated navigation aids should be based not only on the informational aspects of task performance, but also the functional means by which navigators carry out their tasks with conventional technologies such as paper charts.

For the traditional automatic-generation algorithm of electronic chart plan shipping route, it is difficult to achieve the shortest route and the least turning points at the same time. In this article, the optimal and planned shipping route automatic-generation method algorithm based on the rubber band algorithm was put forward. In this algorithm, the elasticity principle of rubber band was adopted to improve the original and basic path and the shortest path and the least turning points can be achieved at the same time. The experimental results showed that the algorithm can quickly and automatically generate an optimal and safe route with good stability and high searching efficiency and so it can be applied to shipping route planning in complicated and large sea area.

In maritime traffic, a route is one or more known tracks along which navigation takes place or there is intention to sail. Meteorological factors are important if the route exceeds the distance of 1500M [1]. Meteorological navigation is the selection of a navigational route in view of meteorological factors and control of vessel during heavy weather conditions and safe navigation aimed at the protection of human lives, vessels and cargo during heavy weather. The paper proposes a model of grouping and evaluating estimates of meteorological factors when planning meteorological navigation. It is advised to upgrade the Electronic Chart Display and Information System – ECDIS program with the aim of allowing for the computer planning of meteorological navigation. KEY WORDS: planning of navigation, meteorology, optimal route, Electronic Chart Display and Information System - ECDIS

Selection Of

New Santri Admission (Penerimaan Santri Baru) is an administrative process for the selection of new student candidates. The PSB process is always carried out manually at each school institution, especially the Islamic Boarding Schools, which will cause various difficulties from several related parties. Therefore the New Santri Admission System was created online or the term can be called the online PSB. . An idea emerged to create a new student admission information system based on the SQL database. With this system, pesantren or administrators can manage the implementation of student registration for web technology using the PHP programming language and new languages. such as rapid registration and announcements.
