In recent years, cases of motor vehicle theft that occurred in Indonesia, especially in metropolitan cities, are indicated by a high crime rate. Various efforts have been made to suppress this curanmor number for example by using a keyless system on motors used in high-end motors. The need for this system is increasing along with the vigilance of motorcycle owners for the safety of their personal vehicles. Facial recognition-based motor keys using the ESP32-CAM module are designed as an alternative to the safety system on motorcycles equipped with relays as switches to disconnect and connect the motorcycle's electricity. The working system designed on this tool uses facial recognition technology that can distinguish the face of the owner of the motorcycle from the one that is not so that the listed and recognized face will connect and disconnect the electrical current of the motorcycle so that the motorcycle can be started and vice versa. From the implementation and testing process with 40 trials, the tool can distinguish the face of the owner of the motor with the face that is not the owner of the motor as much as 80% for the correct condition and 17.5% for the wrong condition.

Cellular communication technology is experiencing rapid development with the arrival of 5G. This generation targets an increase in data rates and better capacity than the previous generation. MIMO is a technique that can be used to improve the performance of 5G communications. The frequency used this time is the middle frequency because it is considered more likely to be used as a 5G service frequency in Indonesia and has a larger coverage so as to save network development costs. In this study, the design and realization of a four-element MIMO antenna for 5G communication at a frequency of 3.5 GHz was carried out. The antenna used this time is a four-element MIMO antenna that has a monopole-based patch form which is then miniaturized so that the antenna has smaller dimensions. This design produces parameters, such as Return Loss on element one of -10.513 dB, for element two of -10.215 dB, for element three of -17.229 dB, and for element four of -14 dB. The value of element one is 1.84, element two is 1.31, element three is 1.31, and element four is 1.49. Bandwidth value ≥ 1500 MHz, and Mutual Coupling value ≤ -19.254 dB.

A Bluetooth was developed as a means for short-range communications. However, the limited range of Bluetooth devices that tend to be narrowly led to the use of Bluetooth is less developed. Whereas, with its properties, sharing of data should be done easily and cheaply. This research has designed a transceiver antenna for Bluetooth communications that works at a frequency 2.4 GHz ISM-band. The antenna is designed in the form of a microstrip antenna with Complementary Split Ring Resonator (CSRR) methods to reduce the dimensions of the antenna. The result of this research is a form of a transceiver antenna that works at a frequency of 2.398 GHz to 2.47 GHz with -30.815 dB return loss and VSWR worth 1,074. The resulting radiation pattern is a directional pattern with a gain of 11.84 dB. Implementation of the CSRR method can reduce antenna dimension by 53.47 %.

The shooting method using UAV (Unmaned Aerial Vehicle ) rides is being thoroughly studied and used in the telecommunication world because it has various benefits. The benefits of UAV are aerial shooting and monitoring process at a location. Monitoring using UAV system require a long distance to get maximum results. The problem is transceiver of antennas did not work optimally for long distances. In this study, the micro strip antenna is designed on the ground segment side using T-junction technique. T-junction is a power divider technique that can support impedance matching on transmission line especially for micro strip array antenna. The coupled technique that used in this paper is the proximity portion coupled with the same height of the upper and lower layers. Then, the materials using Epoxy FR-4 substrate with a dielectric constant 4.4 at a frequency of 5.8 GHz. The simulation and measurements resulted the microstrip antenna that has an unidirectional pattern, circular polarization center frequency at 5.8 GHz, with VSWR â‰¤ 2, the impedance value is 50 Î©, the gain is 8.459 dB, where is in accordance with the specifications of the desired antenna.

Teknologi komunikasi seluler Long Term Evolution saat ini berkembang pesat di Indonesia, salah satunya di kota Bandung. Namun masih terdapat beberapa area yang kualitas jaringannya masih di bawah standar Key Performance Indikator (KPI) , salah satunya adalah area tol Soreang Pasir Koja. Tol sepanjang 10.6 Km tersebut merupakan tol yang baru dioperasikan sekitar akhir 2017 lalu. Maka pada penelitian ini dilakukan perencanaan untuk jaringan LTE FDD di area tol Soreang Pasir koja berdasarkan cakupan area dan kapasitas menggunakan software planning pada frekuensi 1800 MHz. Berdasarkan hasil perhitungan dan simulasi, untuk meningkatkan parameter kualitas sinyal di tol Soreang Pasirkoja dibutuhkan tambahan sebanyak 10 site dan menghasilkan 99.9% nilai RSRP sudah diatas -102 dBm, SINR 99.97% sudah diatas 3 dB. Sedangkan untuk throughput rata-rata sebesar 34.34 Mbps

Pada sistem Synthetic Aperture Radar (SAR), lebar pita menentukan resolusi yang diinginkan. Jika lebar pita sempit, maka resolusi yang didapatkan akan tinggi sehingga objek yang diamati akan lebih presisi. Untuk mendapatkan performa tersebut, dibutuhkan filter yang dapat menjaga lebar pita dari keluaran generator sinyal Chirp. Penelitian ini merancang filter dengan selektivitas tinggi pada frekuensi 1,27 GHz dengan lebar pita sebesar 10 MHz. Dengan karakteristik tersebut, perancangan filter dapat menggunakan resonator berbentuk kotak karena dapat menghasilkan lebar pita yang sempit. Dari hasil perancangan menggunakan duroid 5880 dengan permitivitas relative sebesar 2,2 didapatkan respon frekuensi pada 1,27 GHz dengan nilai S11 sebesar -36,25 dB dan nilai S21 sebesar -0,92 dB. Untuk lebar pita pada rentang frekuensi 1,265 - 1,275 GHz didapatkan nilai S11 dan S21 secara berurutan sebesar -14,37 dB dan -1,09 dB serta -14,43 dB dan -1,08 dB

Sistem informasi yang dibuat pada saat ini masih bersifat individu dengan akses gadget/ponsel, sehingga perlu dibuat sistem yang bisa diakses oleh publik. Khususnya kuliner, Hal tersebut bisa kita temui pada setiap sudut di berbagai tempat di kota Bandung. Tetapi untuk beberapa kalangan yang memakai kendaraan umum informasi tentang referensi kuliner yang dapat dikunjungi dan iklan lainnya tidak terpublikasikan dengan baik. Hal ini sering mengakibatkan ketidakefisienan informasi iklan baik tentang kuliner dan iklan lainnya kepada penumpang pada setiap kendaraan umum di kota Bandung. Dari permasalahan diatas maka dibuat suatu sistem informasi kuliner pada sebuah kendaraan umum berbasis mini pc dengan raspberry pi sebagai media server berikut tampilan digitalnya. Pada proyek akhir ini, akan dibuat suatu sistem pada rasberry pi yang dapat menginformasikan segala jenis iklan baik kuliner yang dilewati oleh kendaraan umum agar lebih mempermudah penumpang mengetahui tempat kuliner yang mungkin dapat menjadi referensi untuk di kunjungi. Dengan di implementasikannya mini pc sebagai media server pada transportasi umum yang diuji selama 6 jam nonstop yang dapat otomatis memutarkan video atau iklan pada awal pertama raspberry pi dinyalakan ini Sangat bermanfaat untuk Mempermudah penumpang mencari referensi Lokasi dan jenis kuliner yang akan dikunjungi melalui video yang ditampilkan.
