Abstract

Selat Melaka merupakan selat tersibuk kedua di dunia, dimana terdapat sekitar 80.000 kapal yang berlalu lalang tiap tahunnya. Sebagai wilayah Indonesia yang berbatasan langsung disisi selatan Selat Melaka, kabupaten Bengkalis memiliki peran penting dalam aktivitas pemantauan dan pengawasan di perairan Selat Melaka. Untuk mewujudkan hal tersebut, maka diperlukan sebuah sistem monitoring yang dapat memantau lalu lintas kapal yang melewati perairan Selat Melaka. Sebagai sebuah sistem yang dapat menangkap sinyal-sinyal kapal yang melintasi selat melaka, Automatic Identification System (AIS) merupakan salah satu solusi yang dapat digunakan untuk melakukan aktivitas monitoring lalu lintas kapal. Penelitian ini berfokus pada rancang bangun aplikasi backend realtime monitoring lalu lintas kapal di perairan Selat Melaka berbasis AIS. Aplikasi backend yang dibangun berfungsi sebagai penyedia layanan pemrosesan data dan RESTful API. Performa aplikasi yang dibangun diukur berdasarkan aspek efesiensi penyimpanan data menggunakan algoritma penyaringan data yang telah dirancang. Dimana dengan menerapkan algoritma penyaringan data diperoleh efesiensi penggunaan penyimpanan data pada database sebesar 18.45%.

Abstract

This study examines the system’s performance with implementation of the energy harvesting (EH) techniques at source node, S and relay node, R. The RF signals which are used to energy harvesting proccess are broadcasted by destination node, D. The information signals from S are sent to D via a R in a cooperative communication framework. The R uses the amplify and forward (AF) protocol to forward the received signal from S to D. We propose a network system which contain of three femto cells, and an access point of each femto cells work as a relay (R), in a macro cell with a base station or eNB as a destination (D). To find the  best R for forwarding the information signal from S to D, we choose the partial relai selection strategy.   From the simulation results can be shown that the throughput system and the outage probability system are affected by the location of S or the distance of between S-R and S-D. Also affected by the access point power of femto cell that is connected to electric source, and  time swithing factor, ρ which is used to harvest energy at S and R nodes. The shorter distance of between S-R and S-D results a better value of  throughput system and the outage probability system, since the gain channel value will be high and increases the SNR value at D. More bigger the power from battery of access point femto cell that is used together with the harvested power by R to forward the signal will result a better value of  throughput system and the outage probability system. More smaller time swithing factor, ρ results more time period for transmitting signal by S and forwarding sinyal by R, therefore increases the transmit power at S and R. Increasing the transmit powers result the increasin SNR value at D, and result a better value of  throughput system and the outage probability system.
