Abstract

Gasoline is an important item and becomes a basic need for the community. Subsidized gasoline in Bandar Lampung experienced sales restrictions according to the specified quota. The price of subsidized gasoline which is cheaper than non-subsidized gasoline makes people willing to wait to get subsidized gasoline. This study aims to determine the factors that influence the selection of gasoline types and determine the preferences of each private vehicle user in choosing gasoline, both subsidized gasoline and non-subsidized types. This research uses AHP (Analytical Hierarchy Process) methodBased on the results of the analysis conducted on the group of civil servants, non-civil servants and students, it was found that the group of non-civil servants chose Premium which was the most priority with a weighting value of 0.3745, then for Pertalite of 0.3156 and Pertamax 0.3108. Then for the group of civil servants, the greatest or priority results were Premium with a value of 0.3457, then Pertamax with a value of 0.3350 and Pertalite with a value of 0.3205. Then, for the Student group the most priority results are Premium of 0.3479, then Pertalite of 0.3288 and Pertamax with a difference not too far at 0.3263.

Abstract

AES Rijndael algorithm is a modern cryptographic algorithm published by NIST (National Institute of Standards and Technology) in 2001 using block cipher mode and using symmetric keys. AES Rijndael as a substitute for DES (Data Encryption Standard) algorithm whose use began in 1977 and has ended. The length of the block cipher used is 128 bits and variations in key length are 128 bits, 192 bits and 256 bits. AES Rijndael's algorithm has a reliability that is the simplicity of the bytes transformation process so that it can streamline encryption and decryption, and has high security.Implementation of the AES Rijndael algorithm will be done on Android devices to secure digital files, which can be used for all types of file types. The parameters used in the analysis are testing of the encryption and decryption processing time, changes in size and bits of the encrypted and decrypted files, then proving the strength of the key length against the robustness of the AES Rijndael algorithm as a symmetric algorithm.
