Abstract
IMTRANSYS (Intelligent Maritime Transportation System) merupakan sistem pemantauan aktivitas kelautan yang memiliki empat fungsi utama, yaitu Monitoring, Controlling, Enforcement, dan Information provider. IMTRANSYS menerima data dari sistem penerima data AIS (Automatic Identification System ) yang tersebar diseluruh area pesisir di Indonesia. Data yang diterima oleh AIS transponder ini kemudian disimpan kedalam basis data IMTRANSYS agar selanjutnya dapat diolah. IMTRANSYS menggunakan teknik konvensional untuk memproses data spasial AIS. Hal ini menjadi masalah ketika jumlah data yang berada pada basis data sangat besar. IMTRANSYS juga masih menggunakan RDBMS (Relation Database Management System) sebagai basis data penyimpanannya. Kemampuan RDBMS untuk memproses data besar dalam waktu cepat dapat dikatakan sangat lamban dibandingkan dengan NoSQL. Terlebih lagi mayoritas RDBMS tidak didesain untuk menangani model data spasial seperti AIS. Geohash merupakan sebuah sistem geocoding domain publik yang mana digunakan untuk mengubah koordinat latitude dan longitude menjadi sebuah string pendek. Geohash dapat digunakan sebagai spasial index sehingga diharapkan dapat mempercepat proses query pada data spasial AIS. Penggunaan basis data NoSQL pada sistem baru juga diharapkan dapat meningkatkan performa IMTRANSYS untuk melakukan penulisan maupun pembacaan data. Hasil pengujian menunjukkan geohash dapat meningkatkan performa sistem untuk melakukan pembacaan data hingga dua kali lebih cepat. Penulisan data pada sistem penyimpanan baru menunjukkan performa 250 kali lebih cepat dibandingkan dengan sistem penyimpanan lama. Latency rata-rata yang bisa dicapai untuk melakukan penulisan data yaitu 0.158 milisekon per query untuk sistem baru dan 40,135 milisekon per query untuk sistem lama.
================================================================================================
IMTRANSYS (Intelligent Maritime Transportation System) is a marine activity monitoring system that has four main functions, namely Monitoring, Controlling, Enforcement, and Information provider. IMTRANSYS receives data from data receiving systems or AIS (Automatic Identification System)
transponders which is spread throughout coastal areas in Indonesia. The data received by the AIS transponder is stored into the IMTRANSYS database so that it can be processed further.
IMTRANSYS uses conventional techniques to process spatial AIS data, namely by querying latitude and longitude. This is become a problem when the amount of data in the database is very large because the database must do the query process twice for each data. IMTRANSYS also still uses RDBMS (Relation Data base Management System) as its storage database. The ability of RDBMS to process large data in concurent can be said to be very slow compared to NoSQL. Moreover, the majority of RDBMS are not designed to
handle spatial data models such as AIS.
Geohash is a public domain geocoding system which is used to convert latitude and longitude coordinates to a short string. With Geohash, it is expected to speed up the query process on AIS data. Whereas Redis is a
storage of data structures in memory so it is expected to provide far better
performance compared to the database model currently used by IMTRANSYS.
The test results show that the latency generated by the proposed system
when writing data is much smaller than the old system, which is up to 0.185
milliseconds. As for data reading, the proposed system shows performance
twice as fast as the previous system.
