Abstract

Android Malware has grown significantly along with the advance of the times and the increasing variety of technique in the development of Android. Machine Learning technique is a method that now we can use in the modeling the pattern of a static and dynamic feature of Android Malware. In the level of accuracy of the Malware type classification, the researcher connect between the application feature with the feature required by each type of Malware category. The category of malware used is a type of Malware that many circulating today, to classify the type of Malware in this study used Support Vector Machine (SVM). The SVM type will be used is class SVM one against one using the RBF Kernel. The feature will be used in this classification are the Permission and Broadcast Receiver.  To improve the accuracy of the classification result in this study used Feature Selection method. Selection of feature used is Correlation-based Feature Selection (CFS), Gain Ratio (GR) and Chi-Square (CHI). A result from Feature Selection will be evaluated together with result that not use Feature Selection. Accuracy Classification Feature Selection CFS result accuracy of 90.83%, GR and CHI of 91.25% and data that not use Feature Selection of 91.67%. The result of testing indicates that permission and broadcast receiver can be used in classifying type of Malware, but the Feature Selection method that used have accuracy is a little below the data that are not using Feature Selection.

Abstract

Rough set theory is one of the mathematical models for dealing with a vague, imprecise, and fuzzy knowledge that has been successfully used to handle incomplete information systems. Since, in fact in the real-world problems, often found the conditions that are the user can not provide all the necessary preference values. In this research, an implementation of extension technique of rough set theory that called limited tolerance relation is used to overcome incomplete information systems in student data at Telkom University. Based on the obtained results, the limited tolerance relation technique successfully used to handle that problem. The results show that the technique achieved the  accuracy of 96.04% with an execution time of 3.1830 seconds.

Abstract

Lectures schedule management in campus is an important aspect that must be implemented in every period. The schedule will be managed well if avoided from collision of the room, time, and lecturer. To overcome collision problem it's necessary to make mitigate system to avoid schedule changes frequently caused by collision of room, time, and lecturer. Thus, the author design and build SIM-DRaW (Sistem Informasi Manajemen Dosen, Ruang, dan Waktu) web-based to fulfill needs and overcome schedule management system. The final result of the design and build SIM-DRaW is implemented information system that can help schedule manager to avoid collision earlier.

Abstract

The BVH data is composed of two parts, the first part detailing the hierarchy and the initial pose of the framework while the second part describes the data for each frame. This data contains the translation and rotation of each joint in the form of coordinates based on X, Y, and Z axes. This study demonstrates methods for modifying BVH data to obtain new movements. First choose the joint on the BVH data, then determine the coordinate point of the initial movement and the coordinate point of the joint end motion. Both select the coordinate point to be modified. The three selected points are rotated using a rotation matrix based on the X, Y, and Z axes. The results of the test will be displayed in the form of animated characters.

Abstract

The development of e-commerce based on marketplace is very familiar in Indonesia. However, there is no digital printing services based on marketplace whereas the need of these services remains high. Currently, the printing house services based on business to customer (B2C) style so people have to compare the pricing and service information directly to print owners both online and offline. One solution to face this problem is to create a marketplace printing services called CETAKIN. By this application, information of printing service in a region can be integrated into this system. This system of printing marketplace integration is built with waterfall method with four stages namely needs analysis, system design, implementation, and system testing with PHP programming language and MySQL Database. The features that exist in this marketplace application is registration, search, order printing services. This information system application provides added value that makes the process of printing search and printing service prices more effective and efficient because people do not need to visit the address of printing. On the other hand, the benefits gained for the store owner can expand the coverage of his store's advertising so that the public know more  the existence of the printing.
