Abstract

Waveguide merupakan suatu alat yang berbentuk menyerupai selongsong persegi ataupun melingkar yang terbuat dari bahan konduktor tunggal. Alat tersebut dapat disisipi dielektrik untuk mengatur frekuensi tertentu atau konverter untuk mengubah mode dari gelombang yang digunakan. Penelitian ini melakukan implementasi konverter mode TE10 ke mode TMmn pada rectangular waveguide dan menggamati karakteristik dari vektor gelombang konverter serta parameter S11 dan S21. Proses pengujian dilakukan dengan mencoba beberapa rancangan dan membandingkan hasilnya, kemudian mengimplementasikannya pada alat. Simulasi dilakukan untuk mendapatkan hasil terbaik. Berdasarkan analisis dari proses simulasi menggunakan software ansoft HFSS, hasil terbaik didapatkan pada konverter mode TMmn parameter dengan rancangan double-trench belah ketupat dan frekuensi cut off 6.4 GHz. Nilai return loss sebesar -14.289 dB dan insertion loss sebesar -0.281 dB. Sedangkan pada rancangan konverter double-trench kembar didapatkan hasil frekuensi cut off sebesar 9.2 GHz dengan nilai return loss -12.878 dB dan nilai insertion loss -0.467 dB. Pada saat pengujian alat yang dilakukan menggunakan Vector Network Analyzer (VNA), frekuensi cut-off yang diperoleh adalah sebesar 7.03 GHz dengan return loss -12.68 dB, dan insertion loss -6.80 dB.

Abstract

The Covid-19 virus originated from the city of Wuhan in China. Transmission is very fast and rapid to various parts of the world including Indonesia. This study discusses the clustering of sources of the spread of the covid-19 virus using the k-means method using software for Cimahi City and West Bandung Regency. The purpose of this study is to obtain information about 5 clusters of the source of the Covid-19 virus, namely cluster 0 (offices), cluster 1 (places to eat), cluster 2 (houses), cluster 3 (shopping), and cluster 4 (public transportation). during May to July 2020 for Cimahi City and West Bandung Regency. The results can be concluded that the highest cluster 0 from Kab. West Bandung with an average of 0,05%, for cluster 1 the highest impact of covid-19 was from Kab. West Bandung with an average of 0,55%, for cluster 2 with an average of 0,02%, for cluster 3 the highest impact of covid-19 was from Kab. West Bandung with an average of 0,04%, for cluster 4 the highest impact of covid-19 was from Cimahi City with an average of 0.79%.

Abstract

This study designed an axial mode helix antenna with a working frequency used of 2.1 GHz, which has a return loss value of < -10 dB and VSWR < 1.3. The simulation was carried out using the CST studio suite 2020 software by designing a helix antenna from the calculation results to optimization of the helix antenna structure, namely the distance between the windings, the number of windings, the diameter of the windings, and the diameter of the ground plane until the simulation results are in accordance with the specifications of the desired parameters. Based on the final results of the return loss parameters and VSWR has met the designed specification standards, from the simulation results of the axial mode helix antenna, the results were obtained, namely at a return loss of -22 dB and at a VSWR value obtained 1.17. The results of the measurement of the axial mode helix antenna obtained the same result at a return loss of -22 dB and at VSWR 1.17 but the frequency value used in the measurement shifted to 2.45 GHz, this is not a problem because the s-band frequency can work from 2 GHz to 4 GHz.
