The exchange of information, still vulnerable amid technological advancements, prompts software developers to enhance digital security strategies. This research conducts experiments by combining three layers of security—Vigenere encryption, Least Significant Bit (LSB) method, and Linear Congruential Generator (LCG) method—as a solution to improve digital security. To assess the accuracy of …
Support Vector Machine is a method in machine learning that can be used to analyze data and sort it into one of two categories. Support Vector Machine has disadvantages in determining the optimal parameter and suitable features, this has an effect on the value of accuracy produced. Therefore, optimization is needed to select the features to be used. This study optimizes the Support Vector Machi…
Stemming and POS-Tagging is part of the pre-processing of raw text data in the natural language processing field which aims to produce more structured data and as an initial step that greatly affects processing performance before being processed at a further stage. In its application for Indonesian text, the efficiency level of process performance for these two stages is still low, especially f…
