Perancangan Perangkat Lunak Pembelajaran Kriptografi Metode Camellia
No full textCryptographic methods aimed at securing data / confidential information that is not known by those who are not interested. In the science of cryptography, many methods that can be used to secure the data. Each method has advantages and disadvantages of each. However, that a major barrier in choosing a suitable method of cryptography is to know and understand the workings of the cryptographic algorithms of the method.
One method of cryptography that there is a method of Camellia. Camellia developed by NTT (Nippon Telegraph and Telephone Corporation) and Mitsubishi Electric Corporation in 2000. Camellia is a block cipher designed by experts in the research and development of cryptographic techniques. Camellia has the same interface with the Advanced Encryption Standard (AES). Camellia encryption and decryption algorithms rotated by using the secret key length 128/192/256-bit and the data blocks of 128-bit
Learning software is able to show the stages of completion of the process of the formation of the key, encryption and decryption are step by step. Learning software also adds the tree view algorithm of Camellia methods to aid understanding of how the algorithm of Camellia method
Kompresi dan Dekompresi File Dengan Algoritma LZSS
No full textA digital data file that contains the information. File size that is too large will be a problem if the files are to be transferred or exchanged. That requires a certain way to reduce the file size. One way for the above problem is the file is compressed by the compression process so that its size becomes smaller than the original size and shorten the time when it is transmitted.
One method that can be used to compress the file size is the method LZSS (Lempel Ziv Storer-Szymanski) that works by placing the characters in the dictionary.
The results of this paper is a software that can compress and decompress back based on LZSS algorithm on all types of files are not compressed. The program can also display the amount of compression ratio, compression ratio, and a long process that has been done on the file and having to enter the password protection facility for secure file compression results. Results of testing with LZSS compression method can also display range reduction ratio
Sistem Informasi Penggajian pada PT. Nubika Jaya
No full textOne of the information system is an information system to process employee payroll data, where the employee\u27s salary which is quite a lot and consists of various critical points that determine the amount of salary, required a computer information system that can process the data quickly and accurately, as well as generate reports from the data. Thus the employee or the employee salaries can be processed quickly, effective, and timely, so there is no delay in payment, and could be a management review report
Simulator Mesin Cipher Hagelin BC-52
No full textSimulator represent imitation form to real situation. Computer program in this time developed many to imitate the way of activity from some equipments. One of the the example is Hagelin BC-52 represent one of the machine of cryptography famous at is second wartime world started from year 1939 till 1945 and still used after finish second wartime. Form or machine model look like typewriter. Used by ground forces and Germany navy to is to communicating with each other to deliver message which have is random. BC-52 created by Boris Hagelin and represent one of the machine of cipher most successful commercially at a period to him. In scheme of machine simulation of Hagelin BC-52 use model of waterfall. Result of from machine simulation of Hagelin BC-52 is a machine of cipher Hagelin BC-52 imitating the way of activity of this machine. In this simulator program also can be done by arrangement to key, lug, and pinwheel of movement bar
Optimalisasi Pemanfaatan Teknologi Informasi dan Komunikasi (ICT) Sebagai Peluang di Era Globalisasi Ekonomi
No full textInformasi untuk globalisasi sudah merupakan prinsip yang sangat mendasar dewasa ini. Perkembangan jaman karena revolusi teknologi informasi membuat akses kenana saja sangat mudah dan gampang. Batas antar negara bukan lagi masalah yang perlu dipersoalkan saat ini. Semua saling terkokeksi karena kemudahan mengakses informasi sebagai ciri dari interaksi global. Semua bangsa dan negara harus menggunakan atau melakukan optimalisasi penggunaan teknologi informasi sebagai peluang untuk bisa bertahan. Apalagi saat ini kita diperhadapkan pada globalisasi ekonomi. Semua Warga negara perlu mengoptimalkan secara maksimal atau melakukan optimalisasi penggunaan teknologi informasi untuk memenangkan persaingan yang makin kompetitif. Globalisasi ekonomi akan jadi peluang jika dikelola dengan baik dan dioptimalkan dengan benar. Bagaimana mengoptimalkan penggunaan teknologi informasi untuk menghadapi globalisasi ekonomi adalah hal yang sangat urgen dilakukan oleh semua warga negara, khususnya sarjana teknologi informas
Perangkat Lunak Dictionary Based Compression Memanfaatkan Transformasi Burrows-Wheeler Dan Byte Pair Encoding
No full textA digital data file that contains the information. File size that is too large will be a problem if the files are to be transferred or exchanged. That requires a certain way to reduce the file size.
One way for the above problem is the file is compressed by the compression process so that its size becomes smaller than the original size and shorten the time when it is transmitted. One method that can be used to compress the file size is by using Dictionary Based Compression (DBC), which works by using replacement strings in the dictionary that will be processed before the Burrows-Wheeler transformation and byte pair encoding technique in which the byte pair encoding technique replaces two pair of characters with a single character, so that the technique can save the data storage capacity.The results of this paper is a software that can compress and decompress back based on DBC algorithm on all types of files are not compressed. The program can also display the amount of compression ratio, compression ratio, and a long process that has been done on the file. Compression test results with the DBC method can also show the range of compression ratios

No full textHouse represent requirement of primary as residence at the price of and expense of which by dozens. Many from society owning limited purchasing power, to lighten society burden in ownership of house, hence bank give credit facility in the form of mortgages. To decide giving of mortgages side bank have to select as well as possible to avoid credit stuck and bank liquidity. This matter can anticipate with existence of progress of technology, passing the process of system supporter of decision (DSS) mortagages. Applying of system of DSS in this program is used to analyse pursuant to data input related to debitor candidate where can be determined by do a the debitor candidate imposed to obtain, get the the facility or not. Resource unavailability, especially which concerning unavailability of source defrayal of long-range housing have an effect on ugly to execution of system defrayal of good itself at a period to now and also at period to come result of examination of application to decision of good enough credit, as according to data related to mortagages and can be concluded that application have result of fulfilling standard

Perancangan Aplikasi Folder Lock Dengan Metode DES
No full textAt this time, many applications have been created to help ease the use of computers. One of the most frequently sought are applications that can help improve security on the computer, so that the data or information that is private and confidential will not be accessible from random people who are not interested. The application is mainly the most frequently sought by the company or organization, because many of the data or information held by the company or organization that should not be known by everyone. Folder Lock application is designed using DES method which has proven to be quite a high level of security. Given the data or information is usually stored in a folder or directory, then the result of the intended application designed to improve security at the folder or directory
