Abstract

QoS (Quality of Service) of LTE networks can bring the providers to provide broadband services with high performance to end user.  Furthermore, the expected data rate transfer is up to 300 Mbit/s per user while the range of bandwidth varies from 1.4 MHz to 20 MHz.  The network worked in 1800 MHz bands, 64 QAM modulation technique and used 10 MHz and 15 MHz channel bandwidth.  There is a congestion problem for LTE network with 10 MHz channel bandwidth due to high utilization.  The paper tries to analyze the QoS parameters, named Key Performance Indicators (KPI) for LTE Networks to solve the problem using bandwidth expansion. The KPIs parameter that is measured by drive test is accessibility, retainability, PRB downlink utilization, and user number.  Based on the KPIs measurements results, it is showed that the proposed method to expand the bandwidth from 10 MHz to 15 MHz can avoid congestion problem and impact on improving the performance of LTE network.

Abstract

Kereta Api merupakan transportasi umum yang banyak digunakan masyarakat di Indonesia karena, dengan Kereta Api masyarakat dapat terhindar dari kemacetan dan juga harganya pun terjangkau. Namun pintu perlintasan Kereta Api di Indonesia memang masih sangat kurang fasiltas di bagian kendali dan pemantauan keamanan perlintasan kereta api sehingga petugas pos yang bekerja mengalami kesulitan untuk memantau keamanan di area perlintasan kereta api. Pada perancangan akan dibuat sebuah alat kendali dan pemantauan secara manual dan berkala yang akan terpantau melalui Android yang terhubung dengan Database Firebase agar dapat membantu petugas pos dan masinis untuk mengupayakan pengurangan angka kecelakaan di pintu perlintasan kereta api. Petugas pos dan masinis hanya cukup memantau pada Smartphone Android yang terkoneksi dengan internet. Dari pengujian dapat disimpulkan purwarupa kendali dan pemantauan pintu perlintasan kereta api berbasis IoT menggunakan Aplikasi MIT Inventor dapat bekerja ketika sensor RFID bergerak dengan kecepatan rata ? rata 12,55 cm/detik yang akan mentrigger motor servo serta kendaraan yang mentrigger sensor ultrasonik yang berada di palang pintu perlintasan kereta api dan dapat  langsung terhubung dengan mikrokontroler NodeMcu dengan menggunakan aplikasi MIT Inventor yang akan langsung diolah oleh Firebase sebagai realtime database. Pada aplikasi MIT Inventor akan menampilkan situasi palang dan keramaian yang ada di area palang pintu perlintasan. Smartphone dan mikrokontroler akan selalu terhubung dengan internet.Kata Kunci: Aplikasi MIT Inventor, Firebase, Internet of Things, Motor Servo, Ultrasonik, RFID

Abstract

Network survivability is a very important issue due to the sustainability of the network services.  Failure in a network system conduce to disturbance of the network services and causes trouble to millions of applications.  Implement an effective redundancy design is one of method to cope nuisance in terms of sustainability in a network. In this paper, there are two design networks with and without redundancy respectively by Metro Ethernet-based technique to support transmission of data and voice. Furthermore, there is a validation performance of networks by measuring and comparing the throughput, latency and jitter between the two network designs. The value of bandwidth capacity is 100 Mbps as plan bandwidth link. Measurements results denote that network with redundancy design is able to enhance performance of the network, the parameters are: the throughput on single link tends to moderate (25%-50%), on the other hand, the throughput values on the main link and back uplink are in accordance with very good condition (75%-100%). The values of frame loss ratio 69.979% - 56.679% (single link), 6.77% -9.999% (main link) and 6.676 %-9.999% (back uplink). The values of jitter and latency in network with redundancy design are much better than in single link network. The recovery time for each frame length is ranging from 48.999ms to 49.887ms, where it is still meet with the standard that must below 50ms. Finally, when the main link in the network topology with redundancy design undergo link fails condition, the backup link is able to maintain the quality of network throughout that time, on the contrary, network topology without redundancy design is unable.

Abstract

Tanaman hias, terutama yang langka, indah dan tidak murah merupakan tanaman yang cenderung memiliki kebutuhan dan perawatan khusus yang harus dijaga dan dipantau secara teratur oleh pemiliknya.Maka diperlukan teknologi yang berfungsi pemeliharaan tanaman secara otomatis yang dapat mengendalikan dan memantau tanaman dari jarak jauh menggunakan smartphone android seperti penyiram tanaman, pendeteksi jarak ketinggian dan kekosongan tangki air, menyalakan atau mematikan cahaya LED, mengetahui suhu dan kelembaban udara sekitar tanaman. Sistem ini dapat dioperasikan dengan mode auto atau manual pada aplikasi android. Jika menyalakan mode auto, maka sistem bekerja berdasarkan pembacaan sensor, dan akan menampilkan status serta nilai pada setiap pembacaan masing-masing sensor. Apabila menyalakan mode manual maka hanya dapat melakukan perintah menyalakan atau mematikan pompa air penyiraman tanaman dan LED grow light. Berdasarkan hasil pengujian, sensor kelembaban tanah akan bernilai 1 jika lembab akan menyebabkan pompa berhenti bekerja dan akan bernilai 0 jika kering akan menyebabkan pompa bekerja, sedangkan persentase kesalahan rata-rata sensor ultrasonic adalah 3.58%, persentase selisih pertumbuhan tanaman dengan sinar LED dan cahaya matahari mencapai 45 %, persentase kesalahan dari pengukuran suhu sebesar 1.72% dan kelembaban sebesar 8.61 %, hal ini membuktikan dengan sedikitnya kesalahan persentase pembacaan sensor, maka sensor soil moisture, ultrasonic, LDR dan DHT22 ini baik untuk di aplikasikan pada alat yang dibuat.

Abstract

Pada tahun 2015 persentase penduduk di daerah perkotaan sebesar  53,3%, proyeksi pertumbuhan penduduk di daerah perkotaan pada tahun 2030 yaitu sebesar 63,4% dan pada tahun 2045 diproyeksikan sebesar 72,9%. Dengan meningkatnya pertumbuhan penduduk akan berdampak pada meningkatnya kebutuhan penunjang kehidupan, salah satunya yaitu kebutuhan akan sayuran. Dengan berkurangnya lahan tanam sayuran dan meningkatnya kebutuhan sayuran maka diperlukan model budidaya sayuran yang dapat diterapkan di daerah pemukiman maupun di daerah perkotaan. Salah satu model budidaya  sayuran yang dapat diterapkan yaitu sistem hidroponik nutrient film technique  (NFT). Oleh karena itu dirancang sebuah sistem yang dapat mengoptimalkan pertumbuhan sayuran pada hidroponik NFT yang dapat mengendalikan kadar nutrisi, keasaman, dan suhu udara secara otomatis yang dapat disesuaikan dengan kebutuhan tanaman menggunkan fuzzy logic. Dalam sistem juga dilengkapi dengan koneksi internet sehingga hidroponik dapat dipantau dari mana saja dengan koneksi internet. Berdasarkan hasil pengujian pada hidroponik NFT sistem kendali fuzzy logic dapat mengoptimalkan pertumbuhan sayuran. Sayuran pada hidroponik NFT terkendali fuzzy logic lebih tinggi daripada sayuran pada hidroponik NFT tanpa kendali fuzzy logic. Lebar daun sayuran pada hidroponik NFT terkendali fuzzy logic lebih lebar daripada sayuran pada hidroponik NFT tanpa kendali fuzzy logic
