Abstract

The information system is a very important thing in education. Up until now, Academic Information Systems (AIS) at the University of Diponegoro assists in the implementation of academic activities of the administrative processes such as charge card plan of study, as well as the central database. Therefore AIS Virtual Classroom integration of Diponegoro University is needed, which adds Ajax technology (Asynchronous JavaScript and XML) and Virtual Classroom functions enriched by being able to apply some functions into a social networking site. Virtual Classroom which already integrated in Diponegoro University Academic Information Systems today still has some problems, such as speed and lack of existing application. One way that can be used to overcome these problems is to apply Ajax technology and the addition of function to send information into social networking sites in this Final Project is Twitter. The steps performed are the system requirements analysis through a study of existing Virtual Classroom on SIA and collecting various references about Ajax, system design using the modeling language UML (Unified Modeling Language), implementation and testing of the system. The results of this study indicate that the addition of Ajax on the Virtual Classroom can provide fast service to access data on choices of the system because it is done asynchronous. These systems also provide facilities for faculty and admin users because some options can be sent to Twitter via a message. Keywords: Virtual Class, Ajax, Information Systems, Social Networks, UML

Abstract

Human iris has a very unique pattern which is different for each person so it is possible to use it as a basic of biometric recognition. To identify texture in an image, texture analysis method can be used. There is some texture analysis method,one of them is wavelet that extract the feature of image based on energy. The texture analysis using energy features which are in the wavelet transform. Based on that reason, in this research made a simulation to identified eyes iris based on Haar wavelet transform. First, the image of iris is segmented from eye image then enhanced with histogram equalization. The method used to extract the feature is Haar wavelet transform. The features obtained is energy value. The next step is recognition using normalized Euclidean distance. Four experiments are done in the research, those are influence of number of sample in database, influence of Haar wavelet transform level, influence of different input image format and testing on eye images which are not in database. As the result, the highest accuration is achieved using Haar wavelet transform level 4 with two samples iris image saved is 85,58%. The lowest accuration is achieved using Haar wavelet transform level 1 with one sample iris image saved is 65,27%. Then, from the test result for the influence of different input image format, the .bmp input image format is better than .jpg input image format. Whereas, from the test result for eye images which are not in database with threshold 2,3653, the recognition level is 81,48%.
