Abstract

Games that hone thinking skills and logical accuracy have recently been very popular. One of them is the game Sudoku. Sudoku is a game that hones logic through puzzles arranged in rows and columns. Sudoku is also defined as a puzzle game that aims to arrange several numbers in a grid from one to nine on a grid consisting of 9x9 squares. The concept of this Sudoku game is to enter numbers into the rows and columns provided. The rule of this game is that the numbers arranged on the board cannot be the same in every row, column, and 3x3 square in the grid. In another sense, each number entered must appear once in each row and column. When running Sudoku, several numbers are already instructions for players to fill in the next boxes. The number of clues at the beginning of the game determines the difficulty level players face. The fewer clues, the more difficult the Sudoku is to solve. This study aims to compare how to solve Sudoku using genetic algorithms, backtracking, and the completion time needed. The tests' results show that the genetic and backtracking algorithms can solve Sudoku games quickly. Still, the backtracking algorithm has the advantage of being relatively shorter, and the process is not so complicated that the backtracking algorithm can be an alternative solution to solving Sudoku logic games.

Abstract

Data mining is a process of collecting important information from large data. Data mining has many functions, one of which is the description function. In this case, the description function is that later data mining can find certain patterns hidden in data. This research aims to identify which association methods in data mining are most often used, identify the most dominant dataset models in association methods, identify the most relevant journal years in association methods, identify what fields most often use association methods, and find out the objectives of researchers using association methods such as FP-Growth and Apriori in various related journals. Using a Systematic Literature Review (SLR) approach, to answer the research questions that have been prepared from the analysis with a total of 33 related journals. So as a result, this study shows that the application of the SLR method can provide answers to the research questions that have been prepared.

Abstract

Tidak dapat disangkal bahwa perkembangan teknologi informasi saat ini menyebabkan peningkatan kebutuhan akan informasi. Peningkatan ini memicu timbulnya kejahatan terhadap informasi yang ditukar, baik dalam bentuk pencurian maupun penyadapan informasi. Akibatnya, informasi yang seharusnya bersifat rahasia menjadi dapat diakses oleh pihak yang tidak berkepentingan. Untuk menjaga kerahasiaan informasi, diperlukan metode tertentu. Salah satu metode yang bisa dipakai adalah algoritma kriptografi ElGamal dan Vigenere Cipher. Algoritma ElGamal adalah algoritma kriptografi kunci publik yang menggunakan kunci publik untuk enkripsi dan untuk dekripsi nya menggunakan kunci privat. Sementara itu, Vigenere Cipher adalah metode enkripsi alfabetik di mana teks dienkripsi melalui pergeseran karakter yang berbeda dalam teks. Penelitian ini bertujuan untuk meningkatkan keamanan pesan teks dengan menggabungkan algoritma ElGamal dan Vigenere Cipher. Hasil pengujian menunjukkan bahwa pesan teks yang dienkripsi dengan menggunakan Vigenere Cipher dan ElGamal menjadi makin sulit untuk diakses oleh pihak yang tidak berwenang karena adanya banyak pergeseran karakter serta penggunaan kunci yang lebih kompleks.
