ABSTRACTEdge detection is segmentation of image input that aims to determine the edge by marking the detail part of an image. From some previous studies it has not been shown the results of detection to be able to separate objects from the center of the image input image itself. The purpose of this study is to perform an edge detection function by dividing into nodes using the concept of the Quadran Tree Classifier method to be applied to the case study of the object colored image of the using national flag. Some input images have different levels of complexity and pixels, including the Korean flag, Wales flag, and the flying Indonesian flag. The method is the adoption of tree data structure, where each has 4 nodes the same number of child nodes. If the node has children, number of nodes must be 4, recursively doing the loop. The working concept of this method split and merge segmentation. The results of object segmentation combined in accordance with the homogeneity of colors, especially those with confusion. This research show which is able to observe the scanning pixel on image Korean flag and the flying Indonesian flag, however level pixel 520 x 347 such as Wales flag, this method is unable to separate between line object that is not nudge. The pixel resolution has an effect with total time execution segmentation (minute/sec), total segmentation identified and the total colour.Keywords : edge detection, quadrant tree, digital image processing, image, segmentation

School management information system is an important application used to manage data and information of a school in order to provide the best service to the community. To create an effective and efficient information system, an effective database design is needed. This needs to be done because if the database is not designed properly, in the future when a system starts to develop, the integrity data stored in the database will decrease. One aspect that needs to be considered is database security. Database security is very important, because the data stored in the database is important information for schools, such as student, financial and employee data. One of the method that can be used to improve database security is Role-Based Access Control (RBAC), which is limiting access to users or roles according to their respective roles. In this study the RBAC method was applied in school management information systems using the PostgreSQL database.

The development of communication is increasingly rapid which does not escape from various threats such as eavesdropping or data theft, because that security aspect of data security is now very calculated. Various ways have been done to secure data that contains confidential information. One method used is to scramble the data into unclear content, so that when tapped it will be difficult to find out the actual information content. Encryption techniques by changing and randomizing the original form of data are called cryptography. Vigenere cipher is one type of classical cryptography algorithm that is popular and often used. This Vigenere cipher uses a substitution technique in encrypting the message where each plaintext character in the message will be encrypted into another character in the ciphertext based on the key used. One Pad algorithm is one algorithm that has perfection when encrypting and decrypting it. The basic concept of the One Time Pad algorithm is almost the same as the Vigenere algorithm, except that in this algorithm the key is generated randomly. In this paper, we will explain how to strengthen Vigenere cipher by modifying Vigenere ciphers. Modifications are carried out by applying One Time Pad encryption generated from the key and the next key generation technique using Vigenere encryption continues so that the key used for the coding will be different from the key used previously. With the use of this method, the connection between plaintext and ciphertext will become less and more difficult to solve cryptanalis.Keywords: Cryptography, Modification, Vigenere Cipher, One Time Pad, and Cyber Security.
