Abstract

. Irrigation  systems in Indonesia are mostly carried out manually in which opening and closing of irrigation channel to rice field are done in traditional way. Internet of Things (IoT)-based control system on irrigation with Wemos D1 ESP8266is a device designed for assisting farmers to ease water irrigation to their rice fields from far away in the real-time. This device aims at improving the farmer effectiveness in working. It used servo motor as the hardware for portal functioning to obtain data from the water height by HC-SR04 ultrasonic sensor as well as serving the control centre by Wemos D1 ESP8266 microcontroller. The control system of irrigation portal was carried out by android application which connected to node controller trough apy key from web hosting. After the portal was opened, the data of water height from controller node was sent and displayed in application. The process of system controlling can be done wher ever and whenever as long as there is a real-time internet connection. The system testing used rice field prototype as the test parameter for the success of control and connectivity functionality. The test employed 3 different connectivity which yielded control delay average with different provider speeds i.e 5.819 seconds, 3.545 seconds, and 7.333 seconds after the controlling process from application.Keywords : android, apy key, Internet of Things, internet, Wemos D1 R2, control.

Abstract

At present technology, specifically in telecommunication sector, develops very rapidly, and mainly adopts Internet Protocol (IP) to support the communication network. In IP networks it involves voice communication commonly called Voice over Internet Protocol (VoIP). It the development of telephone communication using IP networks as paths of data transfer. As it is an open source, its network security becomes a crucial issues in VoIP. One of the ways to cope with the security problems is to adopt Intenet Protocol Security (IPSec) in VoIP networks. The communication trials used two different bandwidths – 375 kbps and minimum bandwidth standard – codec G.711 u. The result of the analysis showed that the trial using minimum bandwidth standard – codec G.711 u was not suitable to be applied in VoIP IPSec network, as in average it had package loss by 58.75%. Accordingly, the VoIP IPSec networks with 375 kbps bandwidth were more superior. In average, with delay rate (3,4956 ms), jitter (6,8894 ms) and package loss (0,00%). In conclusion, VoIP IPSec networks requires large bsndwidth, i.e. : minimally 375 kbps in its operation.
