Abstract

Lamp is a kind of electronic that created light. Light is obtained through the flow of electricity as a current to add a voltage. the die and the life of light are controled  by humans using switch. Applying the  Internet of Things, as known as IoT determined the life and the die of a lamp by determined by the active light censor. The die and the life of the lamp automatically depends on the light sensor by capturing the intensity of the light produced. The result of the function test found that the data in the form of lux value generated by the light sensor, the value is exposed on a website with the display of graphics and websites serve as a web service provides control values to determine the response lamp, if the value of lux above 30 percent then the lights off And vice versa if under 30 percent of the lamps are on, so that a small value will be sent to the lamp and the lamp will respond that the lights are off or on. So that humans only act as a watchdog and control of the value generated by the light sensor.

Abstract

In the development of technology in the current era is one of the most rapid progress, it is marked by almost all managers of data and information has been done with the computer because of the increasingly diverse information issues handled, Detection of objects is one of the most important early stages before Done object recognition process. Eye blink detection can be used to open a new file or an application. In this research use case detection eye blinking on video using OpenCV to open notepad application. The blink detection uses the haar cascade classifier method for realtime detection and the  OpenCV Library. The first step determines the pattern 1111100000. Next enter the video sample avi format to match with a predetermined pattern. In this program the system managed to detect the eye according to the pattern by circling the eye area when the eyes are open or literate and when the eyes closed or brake there is no circle in the eye area for the correct video sample.

Abstract

Fingerprints occur due to stroke differences. These stroke differences have occurred at a time when humans are still fetal form. A normal fingerprint pattern is formed of lines and spaces. These lines are called ridges whereas the spaces between these lines are called valleys. To make an introduction to the fingerprint image requires a variety of support tools. Starting from a fingerprint machine, a smartphone that has a fingerprint sensor and much more. In this research, the acquisition of image is done by grayscaling, histogram equalization, gabor filter, binary, thinning, 8 neighbors, matching.The result of making android application with the method that has been described to show unfavorable results seen from the calculation of the accuracy of 63%. Based on testing the specs android OS devices, this application can run on android with OS 4.4.2 specification kitkat.Fingerprints occur due to stroke differences.

Abstract

The limitations between the amount of bandwidth and users can make the internet slow. Observing the flow of data on the internet network is one way to identify the  bandwidth requirements which used on the STTA office network. This thesis analyzes the data traffic with sharing system model. The observed data is in the category of elastic flow rate, i.e: TCP (Transmission Control Protocol). The traffic data is converted to a measured data graph and then  analyzed  by  traffic  load,  throughput,  and  flow  of  loss  parameters.  The  highest observation value of traffic load is 0.37, Throughput of 9.3 Mbps (93%), and the flow of loss of 23%. From the results of the research, it can be concluded that in general internet network at STTA office is in good category.
