Abstract

The research was conducted to see the trend of supply of students studying at the Interdisciplinary Faculty, Tourism Destination D4 Study Program. The algorithm used in the student supply process is K-means. Data processing with the K-means algorithm helps extract information and knowledge from student data in the Interdisciplinary Faculty, D4 Tourism Destination Study Program. By using data mining, stakeholders in the Interdisciplinary Faculty, D4 Tourism Destination Study Program, can take strategic steps in the screening process in provinces that are indicated to supply students. The K-means algorithm facilitates the process of data analysis and grouping of student data for 4 years. The purpose of this research is to provide an accurate and strategic picture of the provinces that can have a significant impact on the supply of students each year. The results showed that the largest supply of students came from Central Java and the smallest from Bangka Belitung, West Sulawesi, Banten, East Kalimantan, West Papua, Bengkulu and Riau, so promotion strategies need to be improved in areas with the smallest student supply.

Abstract

Data security is one of the most important factors in the world of Information Technology today. One way to secure data is by Block Cipher Cryptography technique. However, some cryptographic techniques have been successfully solved by the cryptanalysis so that new cryptographic algorithms need to be created. The design of Cryptography algorithms based on traditional game patterns of Rangku Alu from East Nusa Tenggara is a design of Cryptographic Block Cipher algorithms that operate in the form of bits designed with 10 rounds where each cycle contains four processes. In each round there are four patterns for the plaintext process and four patterns for the key. The fourth process is transformed with an S-Box table to get a more random ciphertext. Tests were also carried out using Avalance Effect which reached 49,38% and the correlation value where there was a change in character reached 73,44%. So the result designing Cryptographic algorithms can be used for encryption and description in text files.
