Abstract

The library is a service place that is useful as a place to borrow all kinds of books to read or as reference material in the form of images, text or other forms. In simplifying book borrowing strategies, the library utilizes realistic borrowing data as an object for strategy discovery by exploring knowledge that can provide information to simplify the book borrowing system. Data Mining can be interpreted as data mining, where in the data mining process a data mining process is carried out which aims to find important, valuable and useful information in a very large collection of databases. If the data held is very large, it is necessary to carry out a preliminary process as a stage to help simplify the process carried out in data mining, or this process is known as data normalization. One method that can be used in the process of normalizing data is the Z-Score Normalization method. The Z-Score Normalization method is a process in the preprocessing stage by decomposing numerical attribute data which can change the values ​​in the data into a certain range. The Z-Score Normalization method itself can also be combined with other methods such as the CART method. The CART method is a method used to carry out the classification process in data mining. The classification process carried out using the CART method is based on the formation of a decision tree with the binary values ​​obtained. The CART method itself is a method used to assist in processing all types of data such as continuous, ordinal, nominal and other data. The results obtained from the Cart Method research can be applied to obtain book borrowing patterns or book association relationships in libraries in the form of rules which can provide important information about book borrowing patterns in the library

Abstract

To obtain personality criteria based on the work provided, several agencies usually set standard personalities that prospective workers must possess, with the aim that workers can work in fields that support their personalities. Likewise, the Siumbut-umbut Kisaran Village Office sets standard personalities that must be possessed by each employee so that the work carried out has optimal results. This study aims to determine the type of personality appropriate for work in the Siumbut-umbut Kisaran Village Office using the Analytical Hierarchy Process (AHP) method. Decision Support Systems (DSS) are applied to overcome problems in determining standard personalities for employees so that work results are optimal. This study found that the highest personality priority is Phlegmatic (K2), and the prioritized alternative is Eva Wulandari (At1).

Abstract

Cryptography plays a critical role in safeguarding data, making it an essential subject in information security education. Within this course, various algorithms are introduced, each requiring different levels of computational complexity. However, instructional practice has revealed frequent student errors in executing encryption and decryption processes, primarily due to limited understanding of cryptographic algorithms and mathematical procedures. Since accuracy is fundamental in cryptography, miscalculations can lead to incorrect message interpretation. To mitigate these issues, the learning process is supported by CrypTool, a digital aid designed to guide students through encryption and decryption tasks and minimize computational errors
