Penerapan Metode Simple Additive Weigthed Dan Analitical Hierachy Proces Untuk Penentuan Dosen Penguji Skripsi
No full textThe selection of thesis examiners is a crucial process for student academic success, yet it is often based on unstructured subjective considerations. This study aims to address this issue by designing and implementing a Decision Support System (DSS) to provide objective lecturer recommendations. The system integrates the Analytical Hierarchy Process (AHP) method for consistent criteria weighting and the Simple Additive Weighting (SAW) method to rank 10 lecturer alternatives based on four main criteria: Academic Qualification (K1), Time Availability (K2), Total Guidance (K3), and Structural Position Workload (K4). The AHP analysis results indicate that Academic Qualification (K1) is the highest priority criterion with a weight of 0.449 and a highly valid consistency ratio (CR = 0.04). Subsequently, the SAW calculation yielded three candidates who ranked at the top with a maximum preference score of 1.000. This study concludes that the hybrid AHP-SAW model provides an objective, transparent, and efficient framework for the lecturer selection process, successfully delivering accountable recommendations to assist decision-making within the academic environment

This study aims to design an interactive digital comic for the Printing Graphic Design subject at SMKN 5 Telkom Banda Aceh, in response to the limited use of interactive media in classrooms. The research uses a Research and Development (R&D) approach with the ADDIE development model, limited to the development and expert validation stages. The media was built using Scratch, a platform that allows integration of animations, navigation, sound, and interactivity into a single learning tool, offering a contextual and dynamic experience. Validation by two media experts and two subject experts yielded average scores of 92.5% and 96.5%, respectively, categorized as “Strongly Agree,” indicating the media’s high feasibility. The study’s novelty lies in the use of Scratch—a platform rarely applied in vocational learning—for developing interactive comics. Compared to other tools that are mostly static or focused on passive visual design, Scratch provides greater flexibility in programming logic and user interaction, enhancing student engagement. The expected educational impact includes increased motivation, improved conceptual understanding, and strengthened digital literacy among vocational students. However, this study is limited to expert validation and does not include classroom implementation, so its effectiveness in real learning settings remains untested. Future research is recommended to evaluate the media’s impact on learning outcomes through classroom trials and explore the potential integration of technologies like Augmented Reality to further enhance interactivity and learning experiences

Deteksi Malware pada Perangkat Android Menggunakan Ensemble Learning
No full textThe increasing use of permission-based applications on mobile platforms has raised concerns regarding privacy and security. Android, being one of the most widely used operating systems for interacting with mobile applications, is particularly susceptible to various security risks that must be promptly addressed. Low digital literacy and a lack of user awareness about security risks—especially when installing applications from unofficial sources or without paying attention to access permissions—make users vulnerable to malware attacks. Uninformed users can easily become victims of malware insertion by irresponsible parties, turning them into targets for data manipulation and even data theft, which may then be sold on illegal forums. Attackers exploit the permission system, allowing them to freely access the target smartphone. This lack of awareness among users increases their vulnerability to malware injection and subsequent threats such as data manipulation and the theft of personal information, which can be traded on underground markets. One approach to detecting malicious behavior in mobile applications is the use of machine learning techniques. These techniques can analyze application patterns and behaviors based on features such as requested permissions. Popular algorithms for malware detection include Support Vector Machine (SVM) and Random Forest (RF), both of which have demonstrated strong performance in various studies. However, to further improve accuracy and reduce classification errors, ensemble learning approaches such as Adaptive Boosting (AdaBoost) are increasingly being adopted. Ensemble learning combines multiple predictive models to produce more reliable classification results compared to single models. This study evaluates the performance of several classification algorithms in detecting malicious Android applications. The results show that AdaBoost achieved a high accuracy rate of 91.65% and an AUC value of 95%, effectively distinguishing between safe applications and malware. Therefore, the use of machine learning algorithms—particularly ensemble methods like AdaBoost—can serve as a promising solution to enhance the security and privacy of Android-based mobile application users
