ABSTRACK- Sales transaction data stored in the database stores a large number of transaction records, causing the amount of data to continue to increase every day. To explore sales transaction data, data mining techniques are used. One of the goals of data mining is prediction. Prediction is basically an assumption or estimate about the occurrence of an event or event in the future. Through prediction, it is expected to minimize the influence of uncertainty from the future, so that getting results that have the least prediction error is the goal of prediction. This shows that prediction is a very important tool in planning effectively and efficiently. The discussion method used to predict sales is the time series method by using a comparison of two types of prediction methods, namely the Linear Regression method and the Trend Moment method. The use of these two methods will be a better basis for making decisions to determine which method is suitable for predicting future sales. The result of a prediction cannot always be verified in absolute 100%. Therefore, the parameters used to determine the better method are based on the smallest error accuracy rate calculated using MAPE. Based on the results of the comparative prediction analysis of the Linear Regression method and the Trend Moment method, the recommended prediction result is to use the Trend Momnet method because the resulting MAPE error value is smaller, namely 0.439845%. Meanwhile, the MAPE error value with the Linear Regression method is 1.511509%..

Perkembangan teknologi informasi yang semakin pesat memberikan tantangan besar terhadap keamanan data, informasi, dan media penyimpanannya. Jatuhnya informasi ke tangan pihak yang tidak berhak dapat menyebabkan kerugian bagi pemilik informasi, terutama pada file dokumen teks yang sering digunakan untuk berbagi informasi. Salah satu solusi dalam mengamankan data adalah dengan menerapkan teknik kriptografi, yaitu metode penyandian data yang mengubah informasi asli menjadi bentuk yang sulit dipahami melalui proses enkripsi.Penelitian ini memfokuskan pada penerapan dua algoritma kriptografi simetris, yaitu Triple DES dan Blowfish, untuk meningkatkan keamanan file dokumen teks. Algoritma Triple DES merupakan pengembangan dari algoritma DES dengan melakukan proses enkripsi sebanyak tiga kali sehingga menghasilkan panjang kunci 168 bit, yang lebih aman dibanding pendahulunya. Namun, algoritma ini memiliki kelemahan terhadap serangan keysearch attack dan meet-in-the-middle attack. Sementara itu, algoritma Blowfish dikenal memiliki kinerja yang lebih baik dibanding algoritma lainnya dan belum ditemukan kelemahan signifikan dalam keamanannya. Dalam penelitian ini, kombinasi antara algoritma Triple DES dan Blowfish diterapkan dalam aplikasi pengamanan dokumen teks untuk mengatasi kelemahan masing-masing algoritma serta meningkatkan tingkat keamanan data yang dienkripsi. Hasil penelitian diharapkan mampu memaksimalkan peran kedua algoritma dalam proses enkripsi dokumen teks, sehingga data dapat terlindungi dari upaya pembobolan oleh pihak yang tidak berhak.
