Abstract

Science and technology can be collaborated to create an application that can help to track the contacts of COVID-19 patients. Smartphone-based contact tracing applications have been adopted by more than 50 countries. One of which is in Indonesia. In March 2020, Indonesia launched a mobile application to track the contact of COVID-19 patients namely PeduliLindungi.  During its usage, users find some issues about PeduliLindungi, such as potential data leaks, data misuse, and data inaccuracies. This research is aimed to develop a conceptual model to analyze factors that affect user intentions in using the PeduliLindungi application. The proposed conceptual model is the integration of EUCS, DeLone and McLean that is equipped by the system security variables. There were 288 respondents. The data is processed using SmartPLS 3.0. According to the results of the analysis, the proposed conceptual model has 83.1 percent for its accuracy. User satisfaction and system security give a positive and significant impact on user intentions.  The variables of content, accuracy, format, ease of use, and timeliness give a positive and significant impact on user satisfaction. On the other hand, the system security has no positive and significant impact on user satisfaction. Meanwhile, user satisfaction and system security itself affects the user's intentions in using the PeduliLindungi application.

Abstract

The Numerical Method is one of the introductory courses that are useful for students to understand mathematics better. However, the reality on the ground is that students do not understand the material in this course and only use problem-solving methods without understanding its meaning. This research is development research. This research aims to describe the results of the numerical method course module's development, efficiency and effectiveness based on creative thinking. This study uses a modified Thiagarajan development model in three stages: the define, design, and developing stages. This research was conducted with the subjects of fourth-semester students who took the Numerical Method course in the mathematics education study program at the Muhammadiyah University of Purwokerto. This research produces a product from a numerical method course module. Based on the analysis results at the define stage, students still do not interpret the material in the numerical method course, so their creative thinking skills tend to be poorly trained. At the design stage, the module is prepared by training students with creative thinking skills. Finally, at the development stage, the module is validated and tested in the numerical method course. The validation results state that the module is valid and can be used with minor revisions. Furthermore, after being tested, the students' responses were found to be in good criteria, meaning that the module was constructive for students. Then, the results of the creative thinking ability test stated that the results of the creative thinking ability test of students who used the development result module experienced mastery learning. Based on these results, it is concluded that the numerical method course module based on creative thinking skills is valid, practical and effective. Keywords: development, numerical method, creative thinking.

Abstract

The increasing sophistication of cyberattacks necessitates the development of detection systems capable of accurately identifying various threat types. Data imbalance within attack logs presents a substantial challenge that can undermine the effectiveness of detection models. This study introduces a multi-class cyberattack detection model employing the Random Forest algorithm, optimized through the Synthetic Minority Over-sampling Technique (SMOTE) to address data imbalance. The innovative aspect of this research lies in integrating Random Forests and SMOTE to improve multi-class classification accuracy on local attack log datasets. This approach remains sparsely explored in academic research. The dataset consists of 3000 cyberattack logs from the Information Systems Bureau of Muhammadiyah University Purwokerto, spanning 10 cyberattack categories. The research process involved data collection, pre- processing, division, model training, and evaluation. Results indicate that the model achieved an average F1-macro score of 76% and a weighted average of 93%, with the " Threat Level Medium " feature identified as the most influential predictor. These findings suggest that the combination of Random Forest and SMOTE effectively enhances multi-class detection performance and presents promising prospects for log-based cybersecurity systems in educational and industrial environments.

Abstract

Digital evidence in the form of CCTV footage is crucial data in legal investigations, but its integrity and authenticity are often questioned due to the lack of standardization of digital forensic procedures. This study aims to design and test the effectiveness of the implementation of a digital forensic framework based on the international standards ISO/IEC 27037:2012 (guidelines for acquisition and preservation) and ISO/IEC 27042 (guidelines for analysis and interpretation). The research method involves the application of the four-stage procedural ISO/IEC 27037 (Identification, Collection, Acquisition, and Preservation) on a CCTV V380 MicroSD card, followed by analysis using ISO/IEC 27042 principles and Autopsy software. The results show that this framework is fully effective. The integrity of the digital evidence is guaranteed, evidenced by the consistency of hash values ​​(MD5 and SHA1) that are verified Matched throughout the acquisition process until the preparation for analysis. Furthermore, the analysis procedure successfully retrieves information from videos that have been deleted from Unallocated Space, complete with important forensic metadata. This study concludes that the ISO/IEC framework has proven effective in ensuring the authenticity of evidence, and is therefore recommended as a scientifically and legally valid standard operating procedure model for forensic practitioners.
