Abstract

Currently, the Department of Electrical Engineering, Universitas Riau is still using paper documents for internship and final project registration. Thus, the archives that have been stored in a place will be potentially be lost. This is due to human error in management or other reasons. All paper documents need a lot of time, resulting long response to be completed. To overcome this problem, a revolution of online information system is needed in order to save time and provide fast response. The designed online information system is successfully performed using Basic Language and Ms Access as a database for standalone, and MySQL database for website application.Keywords: Internship, Thesis, Database, Website.

Abstract

Long Term Evolution - Advanced (LTE-A) is a 4G wireless broadband technology based on Orthogonal Frequency Division Multiplexing (OFDM). It provides improved system capacity and coverage, high peak data rate and low latency. OFDM technology is used to reduce the Intersymbol Interference (ISI), however it increases the effect of Intercell Interference (ICI) due to single frequency used. The high ICI will give affect to the perfomance of users at the cell edge and cell centre. To avoid the ICI, the ICI management is required.In this paper, the ICI management is described. There are three schemes are analyzed such as Frequency Reuse 1 (FR1), Fractional Frequency Reuse (FFR), Soft Frequency Reuse (SFR). From the simulation results, the best results are provided by SFR. It gives CINR of 21,14 dB, and 40.547,67 kbps of throughputKeywords : LTE, SFR, FFR, Reuse 1, throughput, CINR

Abstract

Improved quality of Long Term Evolution (LTE) network can be do it by analyze the performance and coverage each of operator in Indonesia. Signal strength among of telecomunication operator was not in the same performance and individual location. Parameter that determining signal strenght and quality of each service provider is known by RSRP (Reference Signal Receives Power), RSRQ (Reference Signal Receives Quality), SNR (Signal Noice Ratio), and QoS (Quality of Service). A method to gather series of radio network frequency information in the field is used for analyze and measurement of data signal strength is drive test using G-Net TrackPro software. Location of the measurement are located across panam main street, such as HR.Soebrantas, Soekarno-Hatta, Tuanku Tambusai, SM.Amin, and Air hitam - Kubang Raya. The result shows that XL-AXIATA have the strongest signal on panam with -56dbm, followed by telkosel with -62 dbm. The best 4G LTE strenght is on SM Amin street and the worst is on Air Hitam street.Key words: LTE, drive test, RSRP, RSRQ, SNR, QoS, G-Net Track Pro

Abstract

Cancer and brain tumors are very serious diseases and problems for human health. Early detection of brain tumors is indispensable considering that every year the victims are increasing. Ultra Wideband microwave imaging is a technique that uses electromagnetic signals with wide bandwidth to see through the internal structure of the brain. This study introduces a circular and rectangular array antenna design in a circle configuration that operates in frequency range from 2 GHz to 13 GHz, the antennas are designed and simulated to detect the presence of tumors. The analysis was carried out by comparing E-Field, H-Field, the number of Specific Absorption Rate (SAR) with tumors. With a circle configuration, each antenna element faces directly into brain phantom for better tumor detection. From the simulation results, E-Field and H-Field are obtained in the brain with tumors. The SAR obtained is around 29.7 W / Kg.Keywords: Brain Cancer, Ultra Wideband (UWB), Microwave Imaging, Specific Absorption Rate (SAR), Array Antenna.

Abstract

Access communication fast, flexible and reliable is needed to support the growing information technology. Therefore, needed a network that can meet those criterias, one of which is WiMAX (Worldwide Interoperability for Microwave Access). One of features that is given to optimize the quality of the WiMAX network is to use a modulation technique, such as QPSK, 16QAM, and 64QAM. The purpose of this study is to analyze the performance of WiMAX networks that include Bit Error Rate (BER), Signal to Noise Ratio (SNR), delay and throughput. In this research, the WiMAX network is simulated using OPNET simulator which consists of two scenarios. In Scenario 1 consists of 3 cell with 9 users, while the second scenario consists of 4 cell with 12 users. Research shows that the lowest BER value in scenarios 1 and 2 is achieved with QPSK modulation with a value of 8 x 10-6 and 8,05 x 10-6. While the highest SNR value in scenario 1 and 2 is achieved with QPSK modulation with a value of 34.25 dB and 44.06 dB. The calculation of throughput, highest throughput inscenarios 1 and 2 is achieved with 64QAM modulation with a value of 60.79 Mbps and 52.60 Mbps. As for the delay calculation, the value of the lowest delay in scenarios 1 and 2 isachieved with QPSK modulation with a value of 7.16 ms and 4.20 ms.Keywords : modulation techniques , BER, SNR, delay, throughput
