Abstract

Microstrip antenna when the antenna is one of the very rapid development in telecommunications systems that applied to many modern telecommunication equipment today. One application is the wifi. Wifi (Wireless Fidelity) is a wellknown tech-nology that utilizes an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connection, to provide a network connection to all users in the surrounding area. The purpose of this final project is to design microstrip patch antenna built a circular linier array that can be used for signal wifi stronger. The resulting microstrip antenna working in 2.4 GHz band with the acquisition of gain =3.4301 dBi, VSWR = 1.3749 and radiation pattern unidirectional. This antenna design simulation using the software Ansoft High Frequency Structure Simulator v13. For linear circular microstrip patch antenna array then showed its parameters.Keywords: Microstrip Antenna, Wifi, Array, VSWR, Gain

Abstract

High economic growth makes the demand for comfortable and safe houses increase and the application of technology that is most clearly seen is technology with automatic systems. With this technology, the use of electricity in the house can be minimized and offer convenience in controlling the house. Sometimes homeowners forget to turn off the lights when they are outside the house so they have to go back and do checks that are very inefficient both in terms of time and financially such as the cost of gasoline to return to the house. Based on this, the Smart Home Prototype was created with the concept of the Internet of Things (IoT) using Raspberry Pi Web-Based, which is a system that can remotely control electronic home appliances using Raspberry Pi as a base system, which is connected to Web Applications through the internet network. The electronic equipment used in this study is in the form of 5 lamps, 1 stepper motor to control the garage, 1 servo motor to control the door lock, and 1 brushless motor that functions as a fan. Blocking and overall test results on Bedroom Lights, Living Room Lights, Kitchen Lights, Bathroom Lights, Porch Lights, Garages, Door Locks, and Fans, all work well. The testing of the distance between cities against the Prototype Smart Home was successfully carried out, where the Prototype Smart Home in the City of Demak was successfully controlled by the User who at the time of testing was in the City of Semarang, Kudus, Japan, Surabaya, and Jakarta.

Abstract

Telecommunication technology is currently developing so fast, along with the need for people to communicate. 4G LTE network technology has many positive impacts on service users in communication access. Every provider user wants to have good network quality when used in exchanging information and communications. This study discusses the analysis of the quality of the 4G LTE network in the Purwokerto area by taking a drive test data. Analysis of the drive test is carried out using Map Info software to determine the signal condition in accordance with the range provider and the calculation of the percentage each month with 4G parameters, namely RSRP (Reference Signal Received Power) and SINR (Signal to Interference Noise Ratio). The result of this analysis is a comparison of network quality in December 2019 based on the RSRP and SINR parameter values. In December, the RSRP value that met the standard ≥ = -95 dBm reached a percentage of 77.23% and in March it reached a percentage of 81.86%. For the SINR value in December 2019 which met the standard ≥ = 12 dB, it reached a percentage of 36.82% and in March it reached a percentage of 46.08%. Keywords: Network Analysis, LTE, Genex Probe, RSRP, SINR  ABSTRAK  Teknologi telekomunikasi saat ini berkembang begitu cepat, seiring dengan kebutuhan orang dalam berkomunikasi. Teknologi jaringan 4G LTE memberikan banyak dampak positif bagi pengguna layanan dalam akses komunikasi. Setiap pengguna provider pasti berkeinginan untuk memiliki kualitas jaringan yang baik saat digunakan dalam bertukar informasi dan komunikasi. Penelitian ini membahas tentang Analisa kualitas jaringan 4G LTE di daerah Purwokerto dengan pengambilan data drive test. Analisa drive test dilakukan menggunakan software Map Info untuk mengetahui kondisi sinyal yang sesuai dengan range provider dan perhitungan persentase setiap bulannya dengan parameter 4G yaitu RSRP (Reference Signal Received Power) dan SINR (Signal to Interference Noise Ratio). Hasil dari analisa ini adalah perbandingan kualitas jaringan pada bulan Desember 2019 berdasarkan nilai parameter RSRP dan SINR. Untuk bulan Desember nilai RSRP yang memenuhi standar ≥=-95 dBm mencapai persentase 77.23% dan bulan Maret mencapai persentase 81.86%. Untuk nilai SINR bulan Desember 2019 yang memenuhi standar ≥=12 dB mencapai persentase 36.82% dan bulan Maret mencapai persentase 46.08%.
