Abstract

This study discusses a comparison between the Least Significant Bit (LSB) and Most Significant Bit (MSB) methods in digital image steganography based on image quality parameters using the Mean Squared Error (MSE) value. The LSB method embeds secret information in the least significant bits of each pixel, while the MSB method embeds information in the most significant bits. The test results show that the LSB method produces very low MSE values, ranging from 0.1 to 2, thereby maintaining image quality with changes that are visually imperceptible. In contrast, the MSB method produces high MSE values, reaching 40 and above, indicating significant pixel intensity changes and a considerable decline in image quality. Based on these results, it can be concluded that the LSB method is more effective and secure for hiding data in digital images, as it preserves visual quality and is difficult to detect. Meanwhile, the MSB method is less recommended due to its susceptibility to detection and noticeable degradation of image quality.

Abstract

The rapid development of information technology has significantly transformed the way information is delivered, including efforts to preserve local culture. This research focuses on the implementation of the Multimedia Development Life Cycle (MDLC) method in designing an Augmented Reality (AR) application aimed at introducing the cultural heritage of the Alas Tribe in Southeast Aceh. The Alas Tribe culture, which is rich in traditional values such as traditional houses, clothing, dances, and local wisdom, is increasingly threatened by modernization and the lack of interactive media that can attract the younger generation. Therefore, an innovative digital solution is needed to present cultural information in an interactive, engaging, and accessible way. The MDLC method was chosen because it provides a systematic framework consisting of concept, design, material collecting, assembly, testing, and distribution. Each stage was applied in a structured manner to ensure that the development process runs effectively and efficiently. The AR application enables users to interact with 3D objects representing elements of the Alas Tribe culture through Android devices, offering an immersive learning experience. User testing was conducted using questionnaires, and the results showed that most respondents found the application engaging, easy to understand, and useful for learning about local culture. The findings demonstrate that implementing the MDLC method successfully produces an effective AR application as a medium for cultural education and promotion. Beyond functioning as an educational tool, the application also contributes to cultural preservation and supports the development of the tourism sector in Southeast Aceh. For future development, it is recommended to expand the application by adding more cultural objects, integrating interactive quizzes, and enabling cross-platform compatibility to reach a wider audience. Keywords: Augmented Reality, Multimedia Development Life Cycle, MDLC, Alas Tribe Culture, Learning Media, Cultural Preservation.

Abstract

University of Harapan Medan is one of the private universities in North Sumatra which has an Informatics Engineering Study Program with Good Accreditation. With better accreditation, the number of students who register is also increasing. At the admission of new students, the committee has a huge pile of data, making it difficult in the process of whether the student passed or did not pass. Therefore, in this study, we will implement data mining with the CART (Classification And Regression Tree) algorithm. Data mining is a technique to determine the characteristic pattern of a variable or data criteria with a large amount. In the CART method, the data is first converted into testing data, which will then be used to form a classification tree by calculating the value of information gain, Gini index and goodness of split. From the results obtained, it will be re-determined terminal nodes, marking class labels and finally pruning the classification tree which produces a decision tree. In this study, the number of testing data was 75 with 3 criteria, namely the average value of report cards, CAT test scores, and interview scores. The results of testing data testing using RapisMiner 5.3 software produce 23 number of characteristic pattern rules, where node 1 is the CAT test score, level 1 branch node is the interview score criteria and level 2 branch node is the average report card value.

Abstract

The structure of the Sun’s layers is a complex subject as it involves multiple physical phenomena, making it difficult to understand when explained only through conventional media such as text or static images. This research aims to design and develop an Android-based Augmented Reality (AR) application as a medium for introducing the structure of the Sun’s layers. The method used is the Multimedia Development Life Cycle (MDLC), which includes the stages of concept, design, material collection, assembly, testing, and distribution. The application was built using marker-based AR technology that presents interactive 3D models of the Sun’s layers, accompanied by descriptions and audio explanations to strengthen user understanding. The implementation results show that the application runs smoothly on Android devices, providing key features such as an AR camera and interactive quizzes. Black-box testing confirmed that all functions work as intended, while respondent testing indicated that the application is easy to use, displays 3D objects clearly, and increases students’ learning interest. Therefore, this application is proven to be effective as an innovative learning medium, simplifying the visualization of the Sun’s structure, and enhancing interactivity and engagement in the learning process.
