Abstract

Abstrack - The development of information technology from year to year is increasingly becoming a serious challenge for users of information technology itself and encourages every sector of the organization both formal and informal or other institutions to be able to use it as a support for work activities so that it can produce information that is fast, precise and accurate. PT. Bakrie Sumatera Plantations Tbk Bunut as a company in the field of palm oil and rubber processing certainly requires good management in managing employee attendance data which will later have a positive impact on the development of the company itself. So information is needed that is efficient in maintaining its existence in order to exist and be known by the wider community. One effort to support this is a good computer system. To get a good system, research on the existing system is done. The next step is to do an analysis to find out the strengths and weaknesses of the system. Then the system design is done, namely Flowmap, Data Flow Diagrams, and Context Diagrams. And the last stage is the implementation that changes the design into the programming language stage.

To carry out the elections, of course, they must have candidates as candidates. To become a candidate, the committee selects candidates based on the conditions that have been determined. The selection is done manually. However, candidates come from different faculties and departments which result in all its limitations, the committee will have difficulties and it will take a relatively long time to determine the candidates. Therefore, building a decision support system using the Sugeno fuzzy method to determine student presidential candidates is a good idea. This study aims to design and implement a decision support system with fuzzy Sugeno method, to facilitate the committee in working. This study uses a library research method. Where the source of information is obtained from books, journals, and others. To design a system created using UML. Based on system design, implementation and testing, the conclusion is that a decision support system with fuzzy sugeno method can determine student presidential candidates. The system built can be used as an alternative in selecting student presidential candidates because it can facilitate the committee in processing data to make decisions. Keywords - Prospective Student President, Decision Support System, Fuzzy Sugeno

Abstract

Abstract - Cryptography is an art and science to maintain data security. In maintaining the security of cryptographic data transforming clear data (plaintext) into a password (ciphertext) that cannot be recognized. This ciphertext is then sent by the sender to the recipient. After arriving at the recipient, the ciphertext is transformed back into a plaintext form so that it can be recognized. The method used is the encryption method asymmetrical Rivest Shamir Adleman (RSA). The security of the RSA algorithm lies in the difficulty of factoring large numbers into prime factors. Factoring is done to obtain a private key. Making this application using the PHP programming language. The final result is a desktop-based application that can be used to encrypt text files. This application can be used as a way to secure data, because only authorized people can view encrypted data. Keywords - Cryptography, RSA, Encryption - Decryption, Text, PHP
