Modifikasi Antena Vertical 2 Meter Band 2 X 5/8 Λ Pada Frekuensi 144-147 Mhz Dengan Menggunakan Sistem Sephasa.

Semua radio, baik ketika memancarkan maupun menerima sinyal, membutuhkan antena. Sehingga peran antena sangatlah penting karena antena dapat berfungsi sebagai transmitter maupun receiver, tergantung penerapan dari antena itu sendiri. Untuk antena pemancar sangat diharapkan dapat menjangkau daerah yang luas, sehingga pada penerima dapat mengakses informasi pada daerah yang luas juga. Dengan adanya penambahan elemen dengan modifikasi antena, akan berpengaruh terhadap pancarannya. Pada Penelitian ini antena vertical 2 meter band 2 x 5/8 λ dengan menggunakan sistem sephasa ini memiliki banyak keunggulan seperti pola pancaran gelombangnya yang kuat ke segala arah, bandwidth yang lebar dan memiliki gain yang besar serta area coveragenya lebih luas. Kemudian dilakukan pengukuran dan perhitungan parameter- parameter antena yang telah ditentukan. Dari data yang diperoleh pada saat pengukuran, didapati bahwa frekuensi kerja dari antena hasil rancangan sebesar 145.9 MHz. Diketahui bahwa besar penguatan antena vertical 2 meter band 2 x 5/8 λ terhadap antena vertikal standar 5/8 λ yaitu sebesar 1 dB. Antena vertical 2 meter band 2 x 5/8 λ memiliki bandwidth sebesar 1.4 MHz dan pola radiasi omnidirectional, dengan jangkauan area  coveragenya lebih lua

Unjuk Kerja Transmisi Video Dengan Teknik Pengkodean Spasial Skalabilitas

Video transmission over the internet can be a great possibility of the existence of lost packets (packet loss) and load variations in a large bandwidth. This is a source of network congestion can interfere with the rate of data communication. In this paper the proposed planning optimal error control in scalable video transmission to a video coding technique FGS (Fine Granularity Scalability), which is an improvement on the MPEG-4 video coding, which has outputs are scalable base layer and layer Enhanchement that have different sizes and rates , which the application will be adapted to the transmission network conditions, the ultimate goal is to minimize any distortion from the source to the destination. In the simulation yields a value Peak Signal to Noise Ratio (PSNR) on the base layer of 29, 683 dB and 78,917 dB enhancemenet layer and the base layer for the MSE of 69,998 dB and 0,000834417 dB  enhancemenet layer, Means Square Error (MSE) as the performance of the network system performance on video quality for both the base layer and layer Enhanchemen

Analasis Penerapan Teknologi Traffic Steering SD-WAN Menggunakan Perangkat FortiGate

In the current digital transformation era, network providers have long relied on WAN technology to support the business communications of their multi-local companies; however, in terms of infrastructure, cost, and even effectiveness, WAN technology is no longer sufficient to meet the needs and demands of telecommunications customers. In addition, given the magnitude of the company's need for internet network connections, technology is also needed to manage the use of traffic from rental links in the company so that it can optimize bandwidth usage from the link itself. Therefore one of the technological innovations to improve information processes is cloud-based digital innovation such as SD-WAN Traffic Steering technology. In this paper, the SD-WAN network design will be carried out on FortiGate series 50e devices by implementing traffic steering technology which can adjust a link's traffic flow according to the client's wishes. The results of the data obtained indicate that the utilization of ISP links owned by companies (Lintasarta and MNC) has been able to be used optimally, as evidenced by the use of bandwidth on each link successfully used according to the desired settings, where the settings provided have also been adjusted according to parameters of the type of each ISP service so that functionally the existing service link can be used optimally by the compa

STUDI PUSTAKA STANDARISASI HIGH RESOLUTION QUANTISATION (HRQ) PADA APLIKASI STRUKTUR RF-UPCONVERTER

This paper offers study review of high resolution quantisation schemes for RF-upconverter structures. Thequantisation application in this structure has the function of noise shaping filter which is to distribute quantisation errorsor noise at the lowest position in the desired signal band. Technically, it can simply input the input signal twice thebandwidth and reduce the noise quantisation in the desired signal band. The method used is variety where quantisationversion using all variable clock periods and constant phase references. This method will also be useful in the selection ofvariations in over sampling ratio (OSR) and offset frequency (foffset) used for various quantisation levels used when thebaseband tuning procession will be applied.All digital signal processing (DSP) systems scale with the sample rate and so the higher the sample rate thelarger the bandwidth of the noise transfer function null. This is clearly desirable that such ΔΣ systems are one ofpotential solutions. This also includes their quantiser technique. It is therefore important to make any quantisationprocess fast in best high resolution
