Abstract

Practicum registration systems that exist on campus STTA previously done manually, where students will sign up to the admin to bring proof of payment practicum. Students are free to choose his own class, this often resulted in unbalanced number of students in the classroom lab that is consideredless  effective way. This makes the emergence of the idea to establish an MM algorithm is applied to a practical application o f automation systems. MM algorithm works by determining many lab classes based on students who took the KRS. Furthermore, students who have paid practicum will be immediately incorporated into the classes that are available with regard to the number of students and GPA o f students per class, so it will obtain practical classes by the number o f students and the average GPA o f each class balanced.Concept application using client-server database, where the database is on the Local Area Network (LAN) STTA. To facilitate the management admin, then the application will be tested on the LAN network and VPN (Virtual Private Network) network. LAN is a computers network that are connected to a computer server by using specific topologies, typically used in areas of the building or area a distance o f not more than 1 km (local area). While VPN is a secure way to access the Local Area Network that is in range, using the Internet or other public network to perform packet data transmission in private. By using a VPN, users can access the computer that is on the LAN even though the user is not in the same location with a LAN.

Abstract

Trust is a key factor in online communication, a hosting that can be accessed quickly and almost never had an error would indicate that the hosting has managed seriously in serving consumers. Therefore a hosting requires regular maintenance and handling of error as soon as possible before consumers feel the effects. On the other side hosting providers need to protect their systems to provide access to others who don’t have the right and protect it using a firewall. Those two things became very difficult to do simultaneously considering the speed and ease of access contrary to the security of the hosting. There are many ways in which the administrators to handling this case.One of many ways is create a private network that can only be accessed from within the network, during time for treatments this private hosting use SMS as  medium, this media have been chosen because it can directly installed within the private network.By using this sms media, administrator can make application that can do the repair server directly without being worried with the danger of the public internet network, because application running on a private network. Applications can also be built more complex so that application will help administrator to monitor condition of the server and repair errors on the server, administrators can do it anywhere without being dependent on a stable internet connection.

Abstract

ABSTRACTTechnology developed in order to facilitate human work that would not be done manually, with the presence of the latest technologies that it is not a work of man may not be done quickly, accurately, and save time. One was for the manufacture of palm data processing applications that provide an overview to the public that it is feasible to plant palm oil or not to do, based on existing data and then recycled into Decision Support Systems. To process these data using the Internal Rate Of Return (IRR) as a method to make decisions based on data that have been processed. In this study processed data is the data of a group of Palm Jl. Salak Linga Kuamang Bungo Jambi. From the results of the data managed by the farmer group Palm block 22, Jalan Salak, Linga Kuamang, with interpolation of 30% per year, with a capital of USD 888,253,000.00 and generate income of Rp 2,063,387,050.00 in if using the Internal rate of Return produce interpolation (I) of 30, 113%. Since IRR> I, then it is worth to continue.

Abstract

Vigenère Cipher is one of the well-known ciphering algorithms of the past. Modifications to Vigenère Cipher algorithm is made to improve its security, making it more difficult to decipher by a cryptanalyst. Due to the nature of the algorithm, these measures have to be taken to maintain the confidentiality of ciphered data.  This research modified the Vigenère Cipher using Catalan Numbers method and Double Columnar Transposition.  Catalan Numbers method is a mathematical method used to randomize the initial key so as to generate a key which is longer and having stronger characteristics; a key which is harder to guess, either by cryptanalysts or by key-deciphering methods. In addition to the first method, Double Columnar Transposition is used to rearrange the position of data in the generated ciphertext in order to make it appear more random, hence slowing down the cryptanalysis process of the encrypted text. Double Columnar Transposition is done by applying columnar transposition twice to the ciphered text. The applied modifications to Vigenère Cipher are then tested using Kasiski Examination. Resulting ciphertexts are known to have randomised characteristics, which made it difficult to guess the ciphering method used to generate the ciphertexts. Tests done using Kasiski Examination {1, 2, 4} proven that the ciphertexts passed the test, hence putting down the possibility of easy deciphering, and the modifications successfully provided a better and stronger encryption to the Vigenère Cipher.
