Modifikasi algoritma Hill cipher dengan matriks kunci berupa matriks ketetanggaan

Cryptography is one of the parts in mathematics, especially applied mathematics. Cryptography is the science that studies how to secure information that we don't want others to know about the information we have. Based on the development of the times, cryptography is divided into two consisting of classical cryptography and modern cryptography. In this paper, the focus of discussion is on classical cryptography. Furthermore, there are many kinds of classical cryptographic algorithms, such as the Caesar cipher algorithm, the Playfair cipher algorithm, the Vigenere cipher algorithm, and the Hill Cipher algorithm. The focus of discussion in this paper is on the Hill cipher algorithm. The modifications made to the Hill cipher algorithm lie in its key matrix. In this paper, it will be shown how to encrypt and decrypt the message we want to send using the Hill cipher algorithm with the matrix being a adjacency matrix. In which case, the adjacency matrix itself is obtained from the representation of the graph. It is hoped that this algorithm can avoid crypt attacks, especially on ciphertext only-attack.Keywords: Hill cipher algorithm, cryptography, adjacency matrix, plaintext, ciphertextMSC2020: 94A60

Optimizing the Profile Matching Algorithm using the Analytical Hierarchy Process in the Selection of Teaching Assistants

The selection of the best practicum assistants is traditionally done through a conventional method, which involves voting by active students attending lab classes. However, upon evaluation, it was found that the results were not accurate. Some cases revealed that assistants were chosen based solely on popularity or recognition among the students, possibly influenced by physical appearance or public speaking skills in front of the class, while other important aspects were not considered. This situation could lead to social jealousy. The problem lies in the difficulty of combining evaluation criteria and determining the relative weights for each criterion in the process of selecting the best practicum assistants at the college. Additionally, there is a lack of objectivity in decision-making during the selection process, resulting in an unstructured and immature decision-making process. Therefore, this research aims to enhance the process of selecting the best practicum assistants at the college through optimizing the profile matching algorithm using the Analytic Hierarchy Process (AHP) method. AHP's role involves checking the weights and making paired comparisons to evaluate each criterion and determine the criterion weights. AHP is also utilized to ensure consistency in determining the weights. On the other hand, the role of profile matching is to provide accurate rankings or comparisons based on the suitability scores between the profiles of potential assistants and the reference profile. The combination of these two algorithms is expected to result in a more accurate selection of practicum assistants by effectively measuring the decision criteria weights. Therefore, the difficulty of combining evaluation criteria and determining the relative weights for each criterion can be minimized. Furthermore, optimizing the profile matching algorithm will enable a more objective decision-making process for selecting the best practicum assistants through more accurate rankings or comparisons based on the suitability scores with the reference profile. Based on this optimization, the collaboration of the two algorithms can achieve comparison results with an accuracy rate of 90%.

Discourse on Adlibs Radio Advertisements: Structure and Cooperative Principles

Abstract This chapter aims at explaining structures and violations of the cooperative principle in adlibs to understand its function in a radio advertisement. This adlib is a new method in radio advertisement in which radio broadcasters read and perform the advertising. Data are collected from the morning program of Gen FM radio. This research applies qualitative method in order to provide descriptive data in the form of written and oral words from observed or targeted individuals. There are two key findings in this study. First, the most often of adlibs structures is an advertisement structure without opening or greeting. It means that the radio broadcasters started adlibs without prior notification. Second, the most violated principle is Grice's maxim of relevance. The radio broadcasters deliberately contravene the maxim of relevance that radio listeners do not think they are listening to an advertisement. Therefore, a radio broadcaster must have skill to deliver adlibs as natural as possible. This research shows the current conditions of radio advertisement from the perspective of linguistics. The success of adlibs radio advertisements relies heavily on the ability in manipulation discursive and pragmatic aspects of language and communication.
Usability Evaluation of The Cinemas Indonesia CGV Application Using Heuristic Evaluation and Pieces Framework

The CGV Cinemas Indonesia application is an application that offers services for buying cinema tickets online. Even though the release of the CGV Cinemas Indonesia application was earlier than other cinema e-ticketing applications, this application actually has the lowest demand, judging from the application rating scale and the total number of downloads.

However, there are also several indicators that have a lower value than the minimum good system limit and need to be evaluated for improvement. In the results of calculations with the Pieces Framework, the final average satisfaction level is 3.5605; where in this case it can be concluded that the level of user satisfaction of the CGV Cinemas Indonesia application is included in the PUAS category. However, in terms of service quality, there are still several indicators on one dimension that need to be considered in the evaluation of improvements by application developers.
Improving ML Accuracy in SQL Injection Detection using NLP and Feature Engineering.

Abstract This research proposes the DSQLIA model, which enhances the accuracy of machine learning (ML) algorithms in detecting SQL injection attacks. Traditional rule-based and signature-based methods face limitations in effectively identifying evolving attack techniques. To address this, DSQLIA employs feature engineering and Natural Language Processing (NLP). Relevant features capturing the unique characteristics of SQL injection attacks are identified and created through feature engineering. NLP techniques are applied to analyze the textual content of SQL queries and extract meaningful information for distinguishing between legitimate and malicious queries. The DSQLIA model evaluates different ML algorithms, including decision trees, support vector machines (SVM), and artificial neural networks (ANN), on a dataset. Various performance metrics such as accuracy, precision, recall, and F1-score are used to assess algorithm effectiveness. Results show that the SVM algorithm achieves the highest accuracy of 0.994, followed by the decision tree with 0.975, and the ANN with 0.966. This highlights the improved performance of SVM in accurately classifying SQL queries. By combining feature engineering and NLP techniques, the DSQLIA model enhances ML accuracy in SQL injection detection, offering a valuable approach to mitigating the risks posed by these vulnerabilities in web applications.
