Abstract

Data and information security transport system is an important thing for prevent information leak and fallen to unaccountable person. Method for securing that, is such as watermaking, steganography, cryptography, and digital signature. As company, PT. XYZ has very important data for secured, because they had data conceded in form of document file such as spreadsheet as that file has changed from mischiveous worker so that data file is not matched with per periode report from IT Staff there. File security system that used is AES128-CBC, that means Adcanced Encryption Standard algorithm with 128 bit length key, with cipher block mode Cipher Block Chaining. AES128-CBC is a cipher block mode for AES in between other modes such as ECB, OFB, CFB, CTR, and XTS. Encrypting process on AES-CBC starting from CBC process first for scrambling input (plaintext) and then processed in an AES algorithm, and decrypting process is reversed that encrypting process when processing AES first and then that AES decrypted result scrambling in CBC process, then that process is final result. It is expected securing document file implemetation can protect document that PT. XYZ owned from conceding and unexpected changing from unaccountable person

Abstract

This research was conducted with the aim of facilitating the selection of prospective new employees at Fajar Toserba Luragung by identifying the personality types of prospective employees. The personality test process for employee acceptance currently does not use an expert system. The advantage gained by using this application is that companies can find out the personality categories of prospective employees more easily and quickly compared to the previous method. This method will provide a solution to determine one's commitment to a company. An expert system is a computer program that tries to imitate or simulate the knowledge and skills of an expert in a particular area. Furthermore, this system will try to solve a problem according to its expertise. The certainty factor is a way of combining trust and disbelief. Qualitative data will be represented as a degree of confidence. The result is that an expert system with the Certainty Factor method can help the personnel department in identifying the personality type of prospective employees by 11.63%. This application can help the personnel department to find out the personality traits of prospective employees and find placement solutions that are suitable for new employees.
