Abstract

Kegiatan pengabdian di SMKN 1 Bukit Sundi Kabupaten Solok bekerja sama dengan Politeknik Negeri Padang dilakukan sebagai kegiatan pelatihan pembuatan dan pembinaan kepada guru, siswa dan admin perpustakaan agar managemen perpustakaan tertata dengan baik lebih efisien. Dari hasil diskusi dengan Kepala Sekolah dan para guru pada tahap awal ini para guru ingin fokus pada kegiatan yang dapat membuat perpustakaan dalam pengelolaan buku, pinjam dan pengembalian yang selama ini masih dicatat pada buku besar atau file excel. Kegiatan ini akan berdampak pada pengembangan tata kelola perpustaan yang berbasis web yang akan memberikan kemudahan akses bagi siswa-siswi dan guru SMKN 1 Bukit Sundi Kabupaten Solok. Kedepannya bagi siswa SMKN 1 Bukit Sundi Kabupaten Solok. Peningkatan efisiensi pengelolaan perpustakaan merupakan target luaran utama yang ingin dicapai. Indikatornya adalah kemudahan akses koleksi perpustakaan secara online, meminjam dan mengembalikan buku, serta mengakses informasi tentang acara-acara dan program-program perpustakaan. Dengan adanya program ini diharapkan mampu memberi solusi kendala yang dihadapi pihak perpustakaan dalam pngelolaan koleksi buku di SMKN 1 Bukit Sundi Kabupaten Solok .

Abstract

Wireless fidelity (WiFi) is a wireless connection using radio technology so that users can transfer data quickly and safely. However, at a certain distance there is a decrease in signal speed on WiFi, as happened in Tursina's rented house located in Pasar Baru. When away from WiFi, the internet speed will decrease and the connection becomes unstable. Therefore, an antenna that has a high gain is needed in the form of a microstrip antenna with a working frequency of 2.4 GHz. This final project aims to design a microstrip antenna with the Defected Ground Structure (DGS) method for wireless fidelity (WiFi) applications at a frequency of 2.4 GHz, and analyse antenna parameters such as return loss, VSWR, bandwidth, gain, and radiation pattern. Where the antenna design uses CST Studio Suite 2019 software. After the simulation results are as desired, then fabrication or manufacture of the antenna is carried out. The simulation results after optimising are return loss -40.79 dB, VSWR 1.019, bandwidth 543.9 MHz, gain of 1.312 dBi and bidirectional radiation pattern. After the simulation is carried out, the next fabrication or manufacture of the antenna. In the measurement of the fabricated microstrip antenna using Vector Network Analyser shows a return loss value of -16.07 dB and VSWR 1.375. the measurement results of the fabricated antenna meet the specifications of a good antenna for WiFi applications.

Abstract

The need for internet connection is very important because everything is connected to each other with the internet, but due to limitations on access points, many areas are still experiencing difficulties in accessing the internet, one of which is the suburban area. Suburban areas that are indicated to be still difficult to reach due to obstacles from buildings, and the influence of weather. In order for the signal to be reached in this area, an 11-element yagi antenna with a working frequency of 1800 MHz is needed which is expected to produce a high gain so that the antenna beam is maximised. This final project aims to design an 11-element Yagi antenna at a working frequency of 1800 MHz, and analyse antenna parameters such as return loss, VSWR, bandwidth, gain, and polaradiation. Where the design of the yagi antenna uses CST Studio Suite 2019 software. After the simulation results are as desired, then fabrication or manufacture of the antenna is carried out. The simulation results after optimising are -26.00 dB, VSWR 1.10, and gain 12.32 dB. After the simulation is carried out, the next fabrication or manufacture of the 11-element Yagi antenna, the measurement obtains a return loss value of -11.29 dB, and VSWR 1.74, although the measurement results are far from the simulation but the results of this measurement have met the requirements of the antenna specifications.

Abstract

As the number of cell phone users increases and the high cost of 4G network infrastructure, the investment needed to build 4G infrastructure is Rp. 278 trillion, so that many suburban cell phone users (suburban areas) get 4G access with poor network quality. So it requires a repeater as an effective solution with a small capital to increase the coverage area in weak signal areas. Yagi antenna is an antenna suitable for long-distance communication with three reflector elements to strengthen 4G signals in suburban areas at a frequency of 1710-1880 MHz. The material for making the antenna consists of aluminum pipe as a reflector element and a director element with a diameter of 8.4 mm and wire as a driven element with a diameter of 4 mm. In the manufacture there is the addition of a balun supply and three reflector elements which can improve the performance of the parameters of the yagi antenna. Yagi antenna testing is carried out in two ways, namely the Anechoic Chamber room and the Telecommunication Electronics Lab. In this test, the transmitter uses a dipole antenna. and for the transmission cable, use a high school connector cable to operate the Anechoic Chamberm device designated by a female student who has been trained in measurements using the Network Analyzer software. From the results of manual measurements and the Network Analyzer, the results of a unidirectional radiation pattern are obtained, the maximum power level is -23.24 dBm, the frequency resonance 1809 MHz, Bandwidth 52 MHz, HPBW 〖25〗^0, FBR 12.97 dB, Gain 8.572 dB, VSWR 1.09, and Return loss -26.6 dB design using MMANA-GAL software simulation shows that the antenna works at frequency 1,800 MHz, antenna impedance 42.84 + j2,906 Ω, VSWR 1.18, Gain 20.66 dB, and FBR 23.77 dB and has a unidirectional radiation pattern

Abstract

This study proposes the design of an antenna that works at the frequency of 2.1 GHz used for fifth-generation communication systems. The antenna is designed with FR-4 Epoxy substrate which has the specification of dielectric constant = 4.3, substrate thickness = 1.6 mm. FR-4 Epoxy substrate was chosen because it has a small dielectric constant value, so antenna losses can be reduced. The antenna is designed to have high gain and directional radiation patterns by the inset feed method and array method. The antennas that have been added with the inset feed method and array method have a return loss area of -47,785 dB, VSWR 1,008, and a gain of 6,393 dB at a frequency of 2.1 GHz. After using the inset feed method, the return loss value was successfully reduced to 95.48%, the bandwidth increased by 4.06% and by using the array method, the gain value increased by up to 95.93% compared to the single-element antenna. This research can be used as a recommendation for the design of receiver antennas in 5G communication systems.
