Abstract

Currently the use of Cloud computing to meet human necessity was become more common. Cloud computing more comfort provide given because of his model is placed in a container and allows easily accessible according to necessity in various locations. One of the Cloud computing platform that is widely started using are Openstack , because of the ability to manage and regulate the entire system through a web-based dashboard, the command line and through RESTful API. One of the supporting components computing system on a platform Openstack is a project that serves as a Ceilometer telemetering data to present the results of the monitoring, but it is still the raw data that require interface for communication data and human beings. This research created a system of data visualization as an interface to use by admin and users in monitoring data usage per instance on a virtual laboratortium. The result from this research is web monitoring interface with differents graphic type and specification to engage admin requirement for analisys in virtual laboratory activity.

Abstract

Internet of Things (IoT) is one of technology that is currently being developed and widely applied invarious sectors. That is supported by the development of IoT device infrastructure which is increasingly sophisticatedand modern so its capable to meet various needs in its application. IoT can also be applied as a tool to assist one'sactivities in daily life within scope of a private network which are called Personal Area Network (PAN), one of themas a reminder tool. Reminders can be used to remind a person on an important condition such as stuff that dropbehind. Sometimes a person forgets to put his stuff so it left behind in a place, and it will bring up a risk that is loss ofstuff. To help the problem is required a reminder device that is expected to minimize the risk that may occur. Thisdevice applies a point to point communication consisting of one transmitter module that is Bluetooth Low EnergyAT-09 and one receiver module that is Android smartphone. This reminder device will activate the alarm on Androidsmartphone when both modules are spaced more than 5 meters. Then, from the implementation of this system will doan analysis of quality of service based on the value of Received Signal Strength Indicator (RSSI) and the distancebetween the two modules. Quality of service’s parameters which will analyze is delay and packet loss. Based on testresults, signal strenght value (RSSI) and packet loss parameters are strongly influenced by barricade media, becausewhen both modules are in unobstructed condition they are indicates a stronger signal strength value and few packetloss occurs. While for the delay parameter is influenced by the data rate transfer of bluetooth devices.Keywords : RSSI, Distance, Bluetooth Low Energy, Quality of Service, Reminder
