Abstract

This research aims to design and implement an application that can determine the percentage of similarity to the C code and post using Rabin-Karp algorithm. In this application the input use is a code C and Pascal who type *. C and *. Pas, while the output of the application is in the form of percentage similarity of both the tested code and the processing time required in each process. The results of this study are called "Similarty Checked" is developed using Borland Delphi 7. This application can determine the percentage of similarity of code under test. On the application of "Similarity Checked", there are 5 stages of a process called preprocessing to prepare the program code before checking the similarity of two documents, that are: case folding, filtering, parsing, k-gram, hashing and two-stage process to obtain the percentage of similarity checking code ie: checking the rabin-Karp algorithm and determination of the value of similarity calculated by dice similarity coeficients. Testing is done by trying out some of the code C and Pascal programs are different, and by using k-gram values ??are different. Based on the testing that has been done, showed that the application has been designed to determine the percentage of similarity of code C and Pascal programs were tested.

Abstract

Seleksi Mandiri Tanjungpura University is one of the entrance method to the college, especially in the TanjungpuraUniversity. Registration of Seleksi Mandiri Tanjungpura University done directly by the candidates of the student. This existing method takes quite a long time. The number of applicants is not proportional to the number of committees that serve and verify the administrative requirements of participants, so this resulted in a queue ofstudent candidates. Online system that used as a service in the registration system have been widely applied in daily life. It proved to minimize the problems that previously occurred. Long lines of queue and paper used as a medium of registration can be reduced and prevented with the online service systems. Electronic form is an application that designed for Seleksi Mandiri Tanjungpura Tanjungpura University registration system. Application form fulfillment will be possible to conduct in conditions of a computer connected or not connected to the Internet. However it can be done at offline. One method to protect data from unwanted party is to randomize the data sent, so if the data is received by the other party, they do not understand the purpose of the data. Blowfish algorithm is an algorithm which is quite good and applicable. Blowfish have varying levels of security, the key length used by Blowfish may vary by the system. The application uses data snap technology by applying service application so it becomes more secure because of the indirect communications with the back end. The results show that the design and testing of these applications can be used for the registration process. Prospective participants will receive a registration receipt cards used to take exams.

One is the development of smart phone with many features and also complex operating system that similar to a computer. Although smart phones have many features that included in the operating system, but long or short messaging service known as SMS is still popular in use. SMS feature that still exist till today, bring out the question about the safety of information if someone wants to send a confidential information via SMS facility. The ease of exchanging information via SMS is misused by some people. Some people with a variety of ways to try to steal information that's illegal. Therefore, we need a way to secure the information that is confidential and important. Encryption process can be used to improve the SMS text message levels of information security. Currently, AES (Advanced Encryption Standard) is used as a standard for cryptographic algorithms. Therefore, it can be developed an SMS application with a text encryption using AES algorithm. Mobile-based applications built on the Android platform. The test results showed that the application can perform encryption of short messages with text to a particular destination number and can not decrypt the encrypted message. Application can help users to send short messages in a secure, fast, and easy.
