Abstract

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 compan

Abstract

All radios, both transmitting and receiving signals, need an antenna. So the role of the antenna is very important because the antenna can work as a transmitter or receiver, depending on the application of the antenna itself. For the transmitting antenna, it is hoped that it can cover a wide area, so that the receiver can access information in a wide area as well. With the addition of elements with antenna modifications, it will affect the radiance. In this study, the vertical 2 meter band 2 x 5/8 antenna using this phase system has many advantages such as a strong beam pattern in all directions, wide bandwidth and has a large gain and wider coverage area. Then the measurements and calculations of the antenna parameters that have been determined are carried out. From the data obtained at the time of measurement, it was found that the working frequency of the designed antenna was 145.9 MHz. it can be seen that the large amplification of the 2 meter band 2 x 5/8 vertical antenna against the standard 5/8 vertical antenna is 1 dB. The vertical 2 meter band 2 x 5/8 antenna has a bandwidth of 1.4 MHz and an omnidirectional radiation pattern, with a wider coverage area.

Abstract

Fibre Optics is a delivery medium to connect network points to multipoint. FTTH is a service provided to customers to meet internet needs in terms of voice, data and video (triple play) services. PT. Telkom has standards for determining network eligibility, namely Power Link Budget and Rise Time Budget. With a case study in Bontomanai Village, Bulukumba, it is possible to simulate the design of the FTTH network to measure BER (Bit Error Rate) for system performance. From the results of network design calculations that the Power Link Budget, one of which is the attenuation from STO to the customer, is 25.65 dB, where this value is still feasible because it is still in the standard range of PT. Telkom is 13 – 28 dB. The Rise Time Budget parameter obtained based on the analysis is 0.262 ns which has not yet crossed the NRZ degradation limit of 0.28 ns. Simulations have been carried out using Optisystem software to measure BER

Abstract

In today’s digital era, reliable and fast connectivity has become an important need for many people Long Term Evolution is a standard for high-speed wireless data communication for mobile phones and other data devices. This study aims to analyze the Key Performance Indicator of the LTE Indoor Network at Mall Mtos Makassar. The mall Mtos Makassar building is a shopping center, a place to watch, a place to play, etc. The Mall Mtos building has 3 large and complex floors. This measurement was carried out with 3 telecommunications operators, namely Telkomsel, Indosat Oredoo, and Xl Axiata. The parameters analyzed include Reference Signal Received Power, Reference Signal Received Quality, Signal to Interface Noise Ratio, Received Signal Strength Indicator, and Throughput Uplink Downlink. The research method used includes the walk test method with 3 floors of Mall Mtos Makassar with Idle and Dedicated mode measurements. The result of the analysis on measurement from the 1st to 3rd floors shows the signal performance between operators, thus the Telkomsel Operator shows a relatively better performance compared to the Indosat Oredoo and Xl Axiata Operators.

Abstract

Nowadays, gas or vapor detection to observe environment situation is very required in many fields. Spectrophotometer method is always used to analyze contain and gas concentrate based on the absorption intensity of light by the gas sample. This research used Light Emitting Diode (LED) series act as a transmitter and light receiver (detector). Above detector surface is layered by a chemical membrane that selective in to the type of gas according the polarization level. This vapor absorption in chemical membrane can cause shrinking the intensity of light that hit the detector. This light will be discarding the load in internal capacitor of the detector. Duration internal sudden discharge of the LED depends on light intensity that hit it. Detector LED series that layered by different chemical membrane is produce different an absorption phase that patterning different discharge time. In this experiment, alcoholic solution and gasoline are used as vapor samples. Identify types of gas using imitation nerve connection method to finding out every type of gas with 80% success.
