Ibnu Rohan Tuharea — 2023-09-30

The escalating use of compact electronic gadgets like smartphones and smartwatches, along with social media platforms, has led to a new dimension of criminal activities. Advancements in digital forensics, which investigates digital evidence, have become noteworthy. Researchers David Christopher Harrill and Richard P. Mislan devised Small-Scale Digital Device Forensics (SSDDF) for examining miniature digital devices used in criminal undertakings. Edlira Kalemi and Sule Yildirim-Yayilgan demonstrated the application of ontology in social media forensics, deciphering Android system frameworks related to social media data extraction. However, their investigations mainly focused on social media, overlooking the role of gadgets used by criminals and victims. Extracting digital data from these devices remains pivotal for securing relevant evidence from social media. Notwithstanding, incorporating SSDDF and understanding Android system structures have significantly contributed to digital forensic methodologies. These enhancements can bolster the investigation process, capturing and analyzing critical digital evidence from compact electronic appliances and social media platforms. The advent of SSDDF and elucidating Android system structures have offered invaluable inputs to digital forensics, enhancing efficacy in amassing significant evidence from small electronic devices and social media platforms.

Meyti Eka Apriyani — 2023-09-30

Currently, Telegram is an instant messaging application that is often used by the Indonesian people as a means of long-distance communication with other users. Telegram also has good security features to protect all data from its users. However, Telegram has a positive impact on its users. This security feature can be used by several people to protect against digital crimes, especially cases of sexual harassment. To overcome the existing crimes, analysis, and forensic methods are needed to help solve crimes. This research is guided by the investigation process using the National Institute Of Justice (NIJ) method and the Naïve Bayes method to classify the conversations found. It can be concluded that MOBILedit Forensic Express has a poor performance in finding digital evidence in the Telegram application and FTK Imager is very good at finding digital evidence in the Telegram application. In this research, the classification process using the Naïve Bayes method has been able to classify conversations that contain sexual harassment or not. Evaluation of the classification method uses a confusion matrix to determine the best classification model.

Muhammad Alfikri Maida Topani — 2023-09-30

Mandarin is a language that is widely spoken and studied by people all over the world. Parents who start enrolling their children in Mandarin language courses from an early age with the hope that their children will become accustomed and proficient in using Mandarin. However, for elementary school children, the difficulty of constructing sentences in Mandarin is a major obstacle for children in the process of learning Mandarin. The purpose of this research is to create a unity-based mandarin quiz educational game application that is useful as an alternative media in the learning process to make it easier to learn. which is useful for a. Help make it easier for tutors in learning activities teaching by utilizing media technology in the form of Android-based educational games. Help students learn Chinese HSK material with a happy feeling and don't feel bored, because the content in the educational game "Mandarin Quiz" is displayed in an attractive way with audio, animation, and games on an Android smartphone. Helping children's enthusiasm for learning to know Mandarin.

System development for users will be developed using the Multimedia Development Life Cycle (MDLC) methodology. Each step or stage of this method is suitable for system development in multimedia applications and these stages can swap positions according to research needs. It is hoped that the results of testing and designing the Mandarin Quiz educational game application using Unity 2D can be further developed so that this application can help increase interest in learning.

The test results and feasibility of this educational game used the Usability Scale System (SUS) which consisted of 46 functions with 10 questions, the final test result was obtained with a score of 88, so that the mandarin quiz educational game was declared acceptable.

Hybird Autokey Cipher Algorithm Implementation Reverse Key and Standard Data Encryption for App-Based Text Messages

Risandio Ilham Lazuardi — 2023-09-30

The development of the internet facilitates public communication in sharing information. Along with the advancement of technology in the communication segment, there were various threats to it. Many applications had sophisticated security systems, but the actions in exploiting these security systems were also increasingly diverse. This study implemented a combination of classic and modern algorithms, namely autokey cipher reverse key and DES to protect data from these crimes. This research develops encryption and decryption applications using the agile method, the technique used because of the time spent on the built progress of applications with a cycle for the development process. With this cycle utilized, the method was suitable for developing applications in the short term and revising or improving applications in each cycle. The research resulted in security applications having the function of helping people secure data so that they could prevent and complicate digital criminal acts.
