Trafik pengguna mobile data untuk layanan akses internet senantiasa mengalami peningkatan dari tahun ke tahun terutama untuk penggunaan layanan mobile broadband dibanding dengan layanan fixed broadband. Kenaikan trafik mobile broadband secara eksponensial ini dipicu dengan munculnya berbagai macam aplikasi, android, jejaring sosial dan media content yang ditambah lagi dengan pertumbuhan berbagai macam perangkat smartphone, tablet, dan mobile PC yang menawarkan beraneka ragam fitur dan teknologi terkini. Teknologi LTE (Long Term Evolution) yang di-standarisasi oleh 3GPP (Third Generation Partnership Project) sebagai organisasi standar internasional merupakan teknologi yang memberikan kecepatan data dan kapasitas yang besar. Dengan akses DL 100 Mbps dan UL 50 Mbps untuk standar teknologi LTE release 8. Sehingga menjadi salah satu solusi untuk mengatasi kenaikan trafik dari pengguna layanan mobile broadband. Dengan menggunakan metodologi dalam tahapan-tahapan pada proses RIA (Regulatory Impact Analysis), hal ini digunakan untuk memilih dan menentukan stategi alternatif tool spectrum management yang dipergunakan dan juga opsi refarming yang paling efektif termasuk dampak dari setiap masing-masing opsi tersebut. Metoda pendekatan voluntary spectrum redeployment dan penerapan netral teknologi yang dilakukan secara transparan dan terbuka melalui konsultasi publik dengan melibatkan stakeholder merupakan strategi alternatif spectrum management yang bisa diterapkan untuk melakukan proses refarming di pita frekuensi 1800 MHz di Indoensia. Dan instrumen spectrum management ini juga digunakan untuk melakukan penataan menyeluruh pita frekuensi 1800 MHz sehingga didapatkan jumlah total lebar bandwidth yang ideal dan kanal alokasi frekuensi yang berdekatan atau contiguous sehingga dapat digunakan dalam penerapan teknologi LTE.

Salah satu badan usaha jalan tol di Indonesia saat ini sedang mengembangkan sistem transaksi Single Lane Free Flow (SLFF) yang menggunakan teknologi berbasis Radio Frequency Identification (RFID). Sistem transaksi Single Lane Free Flow (SLFF) merupakan sistem transaksi nirhenti atau transaksi tol tanpa harus melakukan tapping uang elektronik (E-Toll) pada saat melewati gerbang tol. Pada gerbang tol terdapat alat antena Radio Frequency Identification (RFID) sehingga ketika kendaraan yang menggunakan tag Radio Frequency Identification melewati gerbang tol maka Automatic Lane Barier (ALB) terbuka secara otomatis. Antena RFID bersifat aktif memencarkan gelombang radio RFID kemudian radio tersebut terpancar ke tag RFID yang bersifat pasif. Antena RFID dan tag RFID melakukan interaksi dengan bantuan reader RFID, setelah reader memproses signal RFID maka data yang di hasilkan dari proses tersebut akan di validasi oleh control unit yang bertindak sebagai pengelola dan memproses data yang tervalidasi pada database sistem transaksi SLFF. Setelah validasi sukses maka control unit akan mengirimkan perintah ke automatic lane barrier untuk dibuka atau mengangkat portal. Dalam penerapannya sistem teknologi SLFF yang berbasis RFID dipengaruhi oleh konfigurasi power dan sudut antena RFID terhadap jarak pembacaan dari Automatic Lane Barrier (ALB) ke tag RFID kendaraan. Pengujian dilakukan dengan menggunakan konfigurasi power mulai dari 16 dBm sampai 22 dBm dan untuk kemiringan sudut muali dari 0 derajat sampai 20 derajat sehingga konfigurasi optimal yang didapatkan dari hasil pengujian yaitu dengan power 20 dBm dan sudut 5 derajat dan jarak baca 6,5 meter dimana hal ini sudah di lakukan pengujian dengan mempertimbangkan tidak terjadi tail gating ataupun bouncin

Cats is one of the most popular animals in the world that have various breeds. One of the most popular types is Persian and Angora. It requires discipline and persistence both in maintaining cleanliness and also in providing food in caring cats. Constraints in feeding cats are due to the routine activities of the owner outside the home, so providing cat food every day cannot be controlled properly and can make cats more susceptible to disease. This requires an automatic feeding device that can be used to assist cat owners in providing feed on a scheduled basis. This study uses a microcontroller with Arduino Uno as a control system to control input and output. RTC as a scheduled determinant will give commands to the Arduino Uno to drive the mini servo. Mini servo as the main container activator opens the main container which will later fall into the weighing container. The load cell sensor can weigh the feed which will be poured through the mini servo. The percentage that was tried was up to 99%. It works on the condition that the main container is filled with more feed. However, if the feed is filled with ¾, the feed that comes out will be more precise

The increasing number of motorcycles is one of the factors in the increase in motorcycle theft crimes, a vehicle thief usually uses his own T-shaped key to damage the mechanical system of the ignition lock on a motorcycle vehicle. This research was organized to be a solution in solving the problem of motorcycle theft by designing a motorcycle ignition control system based on IoT using NodeMCU and GPS. Based on the results of the study, it shows that the IoT-based ignition lock control system is able to work optimally in line with what is expected, namely using the Telegram application to activate the relay which makes the NO relay pin connected so that the electrical system in the ignition lock is connected and deactivates the relay which makes the NO relay pin open again so that the electrical system in the ignition lock is disconnected with a response time of ± 15 seconds and ± 16 seconds to get a notification message that the command was successfully executed, and when the relay is inactive if the SW-420 sensor detects vibration, it will immediately send a warning message notification to the Telegram application that the vehicle is in motion. The Telegram application can also find out the location of the vehicle with the help of GPS embedded in the tool that has been made

There are still many people who do not use special rooms for smokers or smoking rooms because the air in the room is stuffy. This research aims to overcome this problem by designing a prototype exhaust fan control system in a smoking room using an arduino uno based fuzzy method. The fuzzy logic method is used to optimize exhaust fan speed settings based on the variables of smoke content, CO gas content and the number of people detected in the smoking room. This system uses several hardware devices such as the Arduino, sensor MQ-2, sensor MQ-7, and sensor proximity. Tests were carried out to verify system performance, including the output voltage of the MQ-2 and MQ-7 sensors regarding changes in smoke levels and CO gas levels, and the distance that can be detected by the proximity sensor, as well as the accuracy of the tool output by comparing the tool output results against MATLAB. The test results of the MQ-2 and MQ-7 sensors can obtain different output voltages at each PPM level. From testing the proximity sensor, the results showed that the proximity sensor can detect objects or the human body up to a distance of 30cm. From testing fuzzy logic with MATLAB, the results of comparing the tool's output value with the MATLAB output value were obtained with an accuracy of 99.673%, which can be concluded that the tool can work well.

This research focuses on designing an automatic chicken feeding device based on Arduino Uno which is designed to increase efficiency and regularity in feeding. This system uses an Arduino Uno as a controller, a servo motor for the feeding mechanism, an infrared sensor to detect the presence of feed, and an I2C LCD to display status and monitoring data. When the sensor detects the feed bin is empty, the servo motor is activated to open, fill the feed, and close the feed bin again. Tests show that this system is able to manage feeding 500 grams of feed to the silo well. The average feed spilled when the servo motor is open is 42.75 grams at a 30° angle, 84.75 grams at a 45° angle, 100 grams at a 65° angle, and 177.75 grams at a 90° angle. This system reduces human involvement and ensures feed is provided evenly and regularly. The infrared sensor has high accuracy, and the servo motor functions well in the feeding mechanism. In addition, feed status can be monitored in real-time via LCD and Serial Monitor. In conclusion, this tool is effective for increasing the productivity and efficiency of chicken farming. Further development is suggested for IoT integration and adaptation for different types of poultry as well as environmental conditions.
