Perangkat Automatic Identification System (AIS) adalah salah satu perangkat yang wajib dipasang pada kapal berukuran lebih besar dari 300 GT. Penggunaan perangkat AIS dimaksudkan untuk meningkatkan keamanan dan keselamatan di laut (SOLAS, Safety of Life at Sea). Penelitian ini merupakan kelanjutan dari penelitian yang telah dilakukan sebelumnya terkait dengan pemanfaatan AIS untuk inspection score pengawasan kapal dan monitoring pipa bawah laut. Hasil-hasil penelitian tersebut mendasari pembangunan konsep dasar sebuah prototype software real time monitoring berbasis AIS. Prototype yang dikembangkan saat ini adalah monitoring real time untuk anjungan lepas pantai dan pipa bawah laut, skor inspeksi kapal, dan ship tracking. mengolah data AIS sedemikian rupa dan membandingkan dengan lokasi fasilitas anjungan lepas pantai dan pipa bawah laut. Monitoring anjungan lepas pantai dan pipa bawah laut memungkinan dalam kondisi bahaya, sistem akan mengirimkan peringatan dini melalui notifikasi telepon seluler, surat elektronik dan media komunikasi lain. Sistem inspeksi kapal bermaksud untuk memonitor lalu lintas kapal dalam daerah perairan tertentu. Oleh otoritas pelabuhan, fitur ini dapat digunakan untuk memudahkan dalam menentukan prioritas kapal-kapal yang akan dilakukan inspeksi. Fitur lainnya yang dikembangkan adalah sistem data historis, yaitu penampilan kembali vessel track dalam kurun waktu, batas daerah perairan atau untuk memperlihatkan jalur/track beberapa kapal tertentu. Pengembangan prototype software ini diharapkan dapat berkontribusi dalam meningkatkan keamanan dan keselamatan operasional kapal dan fasilitas lepas pantai/bawah laut serta meningkatkan efisiensi dalam melakukan monitoring terhadap lalu lintas laut.
In 2002 the International Maritime Organization (IMO) issued Regulation 19 and Annex 17, which requires the Automatic Identification System (AIS) to be installed on every ship with a size of 300 gross tonnages and above. One potential use of AIS as an assistance for anti-collision devices. AIS is not only to be installed on the ship but also can be installed on the shore and act as a base station. Hence, the monitoring of vessel traffic can be done by this base station. Indonesia is an archipelagic country with more than 17,000 islands spread over the country and also known as the second longest coastline in the world at 108,000 km. This paper aims to give some ideas on the establishment of land-based monitoring system infrastructure in Indonesia. Main Base Station (MBS) is used for AIS data storage, AIS data integration and processing in the core while Remote Base Station (RBS) is used for receiving AIS data from ships and then sent to MBS. In general, RBS uses two antenna are omnidirectional and yagi directional, each antenna will connect the AIS receiver. According to this configuration, the coverage of MBS is limited to 100 km into the sea from land. To increase the coverage area, a modification was done by adding several types of antennas and applying into the MBS and RBS integration system. The modification shows that the number of RBS to be installed to cover the same coverage area can be reduced. The MBS and RBS integration are not only covered the Surabaya but also Rembang, Semarang, Cilacap, Cirebon, Jakarta and Cilegon. The result of integration is the total ship each day for almost North Java Island and one place in South Java Island is 507 ship and average ship each day is 240.
The increase in the proportion of the world's cargo transported by ships is increasing every year. This certainly encourages the growth of the number of vessels which ultimately can lead to increased risks, especially the risks to maritime installation due to ships operating around it. The most frequent risks are inter-ship collision, ship collision with offshore platform, or danger to subsea pipeline due to dropped anchor, dragged anchor and ship sinking. AISITS developed by ITS Surabaya is a real time-early warning system that allows us to maintain the safety of maritime installation against hazards generated by nearby vessels. This application can provide early warning before the ship accident occurs and can provide notification of a response that needs to be given to prevent incidents from happening. This application can also identify the danger score of the ship, the level of urgency inspection of the ship, vessel tracking that allows the reconstruction of accidents and other applications including ship service at the port. This application is expected to significantly reduce ship collision rates, particularly in relatively narrow territorial waters. AISITS also provides customized systems that allow the addition of various algorithms to support applicability while at the same time reducing the investment required for hardware and software.
