Abstract

Interactivity is the student activities or relationships between students with anything related to the course, his example by attending a class attendance responds directly at the appointed hour. What is meant here is the liveliness activities interactivity of students to answer the questions that exist in the online lecture forum, whether he is copying and pasting answers with other students or not. The number of student answers archives make web manager can not judge whether the student was copying and pasting the answer to her or not. Therefore we need a system that can provide a connection weights to archives word answers and calculates similarities between students answer word. To analyze the data from these students, writers manipulate the data using text mining. This research using tf-idf method cosine similarity, the parameters used are folding case, tokenizing, stopwords and stemming. The results of this study are that have a common answer to answer other students not considered effective in the online lectures, corresponding similarity weight percentage of statutes that have been determined.

Abstract

Imageis a 2-dimensional intensity function f (x, y), where x and y are the spatial coordinates and f at the point (x, y) is the brightness of an image at a point. An image obtained from the capture of light reflected by the strength of the object. Output image as a recording apparatus, such as cameras, digital games can be analag, Figure itself was composed of pixels that can be taken into account. Thus the images suitable for use as a sample in this study. In this case the process of designing and manufacturing of online attendance system that is able to detect the validity of a student. The system uses the template matching method is used as a student face detection. Mathcing Template Method is a technique in digital image processing to find small parts of the image that matches the image of existing templates. The application will test the input image is detected or not. The results showed that the inputted face image detected correctly. Therefore, the study concluded that Macthing template method is suitable for use in the attendance system.
