Abstract

Managing incoming and outgoing mail is a crucial part of administrative activities in higher education institutions, including STMIK Neumann Indonesia. Currently, the process of recording and archiving mail is still done manually, which can potentially cause various problems such as delays in processing mail, lost documents, and difficulties in searching archives. To address these issues, a computerized and integrated Incoming and Outgoing Mail Management Information System application was developed. This application is designed with a web-based approach using the PHP programming language and a MySQL database. The main features developed include managing incoming and outgoing mail, agency data, mail classification, user management, and mail reports. This system is also equipped with an access rights-based login function to maintain data security. Test results show that the application can help administrative processes be faster, more efficient, and well-documented. By implementing this information system, STMIK Neumann Indonesia can improve the effectiveness of administrative services, accelerate the flow of mail disposition, and create a structured and modern digital archiving system.

Abstract

Electronic voting (e-voting) systems have emerged as a critical research topic in the fields of information security and modern election technology. However, various studies have shown that e-voting systems still face several vulnerabilities, particularly in security aspects. One prominent weakness often highlighted is the direct involvement of voters in cryptographic technical processes, such as unblinding, which may lead to negligence and technical errors. This aligns with Bartjan Wattel’s assertion that "The real security challenge lies in protecting business processes from authorized users with malicious intent or who act carelessly" indicating that threats to security do not only originate from external intruders, but often from legitimate users with access rights. This study proposes a solution to minimize the voter’s technical involvement by implementing a Blind Digital Signature protocol based on the RSA algorithm, wherein the entire cryptographic process including blinding, signing, and unblinding is carried out by the system and authorized entities. The goal of the study is to develop an e-voting protocol that reduces voter participation in system security processes (frictionless), and to measure the security level of the implemented protocol. The results show that reducing the voter’s technical role in the cryptographic process enhances security and minimizes errors, as the blinding to unblinding stages are controlled by the system. Moreover, the protocol is modified to include digital signatures during access requests in inter-party communications, preventing forgery and ensuring that only authorized entities can participate in the system.

Abstract

This study explores the use of deep clustering methods to automatically group handwritten essay answer sheets based on their visual patterns. Feature extraction was performed using three backbone models: ResNet-50, Vision Transformer (ViT-base), and Tr-OCR. These features were then clustered using two unsupervised algorithms—K-means (with k=5) and HDBSCAN (with minimum cluster size = 10). To enhance clustering performance, a deep clustering approach was implemented by applying K-means iteratively to refine feature representations. Evaluation was conducted both quantitatively, using Silhouette Score, Davies-Bouldin Index, and Calinski- Harabasz Score, and qualitatively, through t-SNE visualizations and cluster content inspection. The ViT and Tr-OCR backbones outperformed CNN-based ResNet-50, achieving higher cluster cohesion and separation. Notably, the final clustering result using ViT with HDBSCAN reached a Silhouette Score of 0.772, Davies-Bouldin Index of 0.369, and Calinski-Harabasz Score of 408.006. The findings indicate that vision transformer-based models are more effective for unsupervised grouping of handwritten visual data. This approach can assist educators in accelerating and objectifying the grading process and may serve as a foundation for future automated essay evaluation systems integrating OCR and NLP techniques.

Abstract

This study aims to apply the National Institute of Justice framework in the digital forensic process for conversations retrieved from LINE and Telegram applications, as well as to explore the utilization of a Predictive Classification Model for automated text-based comment classification in cyberbullying cases. Cyberbullying is a growing form of digital crime, particularly on private and encrypted instant messaging platforms that are difficult to monitor. The research employs two machine learning algorithms within the PCM framework Complement Naive Bayes and Random Forest to detect potentially abusive comments. The forensic process follows several stages: Preparation, Evidence Assessment, Evidence Acquisition, Evidence Examination, and Documenting and Reporting, with a secure and forensically sound data extraction approach from both applications. Due to data limitations from LINE and Telegram, the classification analysis is conducted using an Instagram comment dataset that reflects the cyberbullying context. Evaluation results show that the Complement Naive Bayes model outperforms Random Forest, achieving an accuracy of 86% with balanced F1-scores, while Random Forest achieves 75% accuracy. These findings support the use of PCM as an effective aid for automatically identifying high-risk content on social media. The integration of digital forensics and artificial intelligence has significant potential to enhance the effectiveness of cyberbullying investigations. Keywords: Cyberbullying, Predictive Classification Model, Complement Naive Bayes, Random Forest, LINE, Telegram, Digital Forensics, National Institute of Justice
