Abstract

Activities such as planting and gardening become one of prominent hobbies. An issue of having such well grown plants is the impractical and unachieavable task to monitor 24 hours a day, thus we need a smart gardening system that can monitor the garden on demand. One of the problems in residential gardening systems is how to water the plants while the owner is not at home. Some of people have an adequate knowledge of using IoT to make their life easier. This paper proposes a simple automatic gardening system in watering several plants as programmed. In addition, this system allows human’s manual intervention either locally or remotely via Internet, to control a water pump. To build this smart gardening system, we use Xiaomi home application from Google Play. In this application, we can set the program to water the plants daily with definite time periodic independently.

Abstract

Nowadays, security and gardening systems in densely populated residential areas are generally done manually. The security system in housing sometimes places security posts at street corners that are some distance from citizen’s homes thus they cannot be monitored at all times. Whereas other problem of watering system in citizen’s homes, someone has to water the plants one by one that it is not efficient in  energy, time and water availability thus that it can reduce the quality of the plants. Internet of Things (IoT) is a concept and method for remote control, monitoring, and various tasks. IoT is connected to a network that it can be accessed anywhere which can make things easier. IoT can be used to solve various problems. One of them is security issues and gardening activities. By using smart home technology, the security system is carried out by placing CCTV (Closed Circuit Television) which can be accessed by the home owner, anytime and anywhere the home owner is located. On the other hand, gardening is one of the most popular hobbies. In this field, IoT can be used to monitor and regulate various things to support gardening activities. In this community service activity, we are proposed a simple automatic gardening system for watering some plants programmatically in Pondok Hijau Indah residence. The system also allows manual human intervention either locally or remotely via the internet to control CCTV and water pumps. To build this smart Home system we will use the Xiaomi Home application from Google Play. In this application, we can set a program to control CCTV and water the plants every day at a certain time periodically, in this case, we set every 7 hours to watering the plants.

Abstract

In this paper, the implementation of an optical repeater for indoor visible light communication using the amplify-forward method was proposed. In indoor, visible light communication (VLC) can occur by transmitting information signals from lamps as a VLC transmitter toward the VLC receiver as line-of-sight (LOS) that is located with only a few meters. In the non-los (NLOS) communication, the signal will be attenuated, so it needs to amplify to improve good signal quality in a VLC receiver. The optical repeater could be used to improve the signal quality that attenuating due to distance. The audio signal was generated and sent using VLC Transmitter toward the light emitting diode (LED). Then, the electrical signal was converted to become visible light, and it was amplified using an optical amplifier with an amplify-forward method. The signal in the form of visible light that had been amplified would be received by the photodiode (PD), and the VLC receiver processed it. The measurement results showed the system that used the optical repeater could improving the distance until 9.5 m with frequency 6000 Hz, where the best signal quality at a frequency of 3000 Hz. The measurement result showed that the use of repeater components with the amplify-forward method for VLC systems, especially in the room, can increase the range until 4.5 m compare without an optical repeater. This result exceeds the minimum distance of an indoor visible light communication system, with an average distance of the roof to the floor is 3.5 m.

Abstract

ABSTRAKEIGRP (Enhanced Interior Gateway Routing Protocol) dan OSPF (Open Shortest Path Fisrt) adalah routing protokol yang banyak digunakan pada suatu jaringan komputer. EIGRP hanya dapat digunakan pada perangkat Merk CISCO, sedangkan OSPF dapat digunakan pada semua merk jaringan. Pada penelitian ini dibandingkan delay dan rute dari kedua routing protokol yang diimplementasikan pada topologi Ring dan Mesh. Cisco Packet Tracer 5.3 digunakan untuk mensimulasikan kedua routing protokol ini. Skenario pertama adalah perancangan jaringan kemudian dilakukan pengujian waktu delay 100 kali dalam 5 kasus. Skenario kedua dilakukan pengujian trace route untuk mengetahui jalur yang dilewati paket data lalu memutus link utama. Pada skenario kedua juga dilakukan perbandingan nilai metric dan cost hasil simulasi dengan perhitungan rumus. Skenario ketiga dilakukan pengujian waktu konvergensi untuk setiap routing protokol pada setiap topologi. Hasilnya EIGRP lebih cepat 386 µs daripada OSPF untuk topologi Ring sedangkan OSPF lebih cepat 453 µs daripada EIGRP untuk topologi Mesh. Hasil trace route menunjukan rute yang dipilih oleh routing protokol yaitu nilai metric dan cost yang terkecil. Waktu konvergensi rata-rata topologi Ring pada EIGRP sebesar 12,75 detik dan 34,5 detik pada OSPF sedangkan topologi Mesh di EIGRP sebesar 13 detik dan 35,25 detik di OSPF.Kata Kunci: EIGRP, OSPF, Packet Tracer 5.3, Ring, Mesh, KonvergensiABSTRACTEIGRP (Enhanced Interior Gateway Routing Protocol) and OSPF (Open Shortest Path Fisrt) is the routing protocol that is widely used in a computer network.

Abstract

ABSTRAKPada kondisi pembangunan suatu jaringan seluler baru, permasalahan coverage area terkadang perlu penanganan khusus. Jika coverage area dari suatu base station terlalu besar maka dapat mengakibatkan saling tumpang tindih (overlap) dengan sel yang berdekatan. Hal ini akan meningkatkan interferensi daya antar sel, yang kemudian berakibat pada penurunan kualitas layanan. Salah satu bentuk solusi untuk dapat memenuhi persyaratan coverage area, kinerja jaringan seluler, dan juga memenuhi tingkat keselamatan engineer adalah dengan menggunakan metoda down tilting antenna melalui wireless. Penetapan metoda down tilting antenna dilakukan dengan membuat suatu peralatan yang dapat menggerakkan posisi antenna pada base station. Perangkat yang diimplementasikan terdiri atas Transmitter, Receiver, Motor DC, Driver Motor, Logam Pengait, dan Antena. Sinyal yang berfungsi sebagai pengendali masuk ke Transmitter dan selanjutnya diolah oleh Receiver. Sinyal keluaran dari Receiver digunakan untuk mengendalikan motor DC melalui driver motor yang mengendalikan pergerakan dari Antenna Base Station. Pada penelitian ini, sistem telah dapat diuji memalui pergerakan antenna sampai dengan jarak 10 m. Tingkat kemiringan antena dibandingkan dengan pergeseran logam berkait menunjukan hasil yang linear. Setiap pergeseran 0,5 cm akan menyebabkan perubahan kemiringan antenna sebesar 1 derajat. Kata kunci: Remote Tilting, Motor DC, Transmitter, Receiver, Base StationABSTRACTOn the state of development of a new mobile network, problem coverage area sometimes need special handling. If the coverage area of a Base Station is too big then it may lead to overlap ( overlap ) with adjacent cells. This will improve inter- cell interference power, which then resulted in a decrease in the quality of service. One form of solutions to meet the requirements of the coverage area, the performance of cellular networks, and also meet the level of safety engineers is to use the method of tilting down through a wireless antenna. Determination method of antenna down tilting is done by creating a device that can move the position of the antenna on Base Station. The device is implemented consisting of Transmitter, Receiver, Motor DC Motor Driver, Metal Hook , and Base Station Antennas. Which serves as a signal controlling entry into Transmitter and subsequently processed by the Receiver. The output signal of the receiver is used to control a DC motor through a motor driver that controls the movement of Base Station Antenna. In this study, the system has to be tested memalui antenna movement up to a distance of 10 m. Levels compared to the friction slope antenna hooked metal has showed linear results. Each shift will lead to a change of 0.5 cm by 1 degree slope antenna.Key words: Remote Tilting, DC Motor, Transmitter, Receiver, Base Station
