Abstract

Di era digital yang serba cepat ini, flashdrive menjadi salah satu metode penyimpanan yang paling populer. Saat-saat tertentu, data flashdisk dapat hilang, dan kehilangan data ini dapat membawa konsekuensi yang signifikan baik secara profesional maupun pribadi. Dalam penelitian ini, contoh pemulihan data dari flashdisk yang tidak dapat diakses setelah dicabut secara paksa selama proses transfer data dibahas. Metode forensik statik dan alat Disk Drill, berhasil menemukan sebanyak 7626 file dari partisi yang tidak teralokasikan dengan ukuran total 17,3 GB. Bukti digital yang telah dipulihkan sebanyak 49 files yang disajikan dalam bentuk file dengan berbagai ekstensi, seperti gambar, audio, dokumen, dan arsip. Kemampuan alat pemulihan data yang canggih memungkinkan pemulihan berbagai jenis file, yang meningkatkan peluang untuk menyelamatkan data yang hilang.

Abstract

The National Data Center (PDN) plays a critical role in storing and managing government and public data, positioning it as a strategic target for cybersecurity threats such as ransomware. This study aims to assess university students’ knowledge of PDN security issues, with a specific focus on ransomware attacks, before and after attending a structured webinar series. A pre-test and post-test design was implemented involving students from Universitas Siber Muhammadiyah and Universitas Islam Mulia Yogyakarta. The results revealed a significant improvement in students’ understanding of cybersecurity issues following the webinars. Key contributing factors included educational background, frequency of technology use, and active participation during discussions. The findings suggest that webinars are an effective educational tool to enhance cybersecurity literacy among students. The study recommends integrating cybersecurity awareness into the academic curriculum and conducting more webinars to address the growing complexity of digital security threats.

Abstract

In this fast-paced digital era, flash drives have become one of the most popular storage methods. At times, flashdrive data can be lost, and losing this data can have significant consequences both professionally and personally. In this study, an example of data recovery from an inaccessible flashdrive after being forcibly removed during the data transfer process is discussed. Static forensic methods and the Disk Drill application succeeded in finding 7626 files from unallocated partitions with a total size of 17.3 GB. The digital evidence that has been recovered is 49 files which are presented in the form of files with various extensions, such as images, audio, documents and archives. Advanced data recovery tool capabilities enable recovery of various types of files, which increases the chances of rescuing lost data.

Abstract

The National Data Center (PDN) is a vital infrastructure that is vulnerable to various cybersecurity threats, including ransomware. This study aims to measure the improvement of students’ knowledge regarding cybersecurity after participating in a webinar-based educational activity. The research employed a quasi- experimental method with a one-group pre-test–post-test design involving 50 students from two universities. The research instrument consisted of pre-test and post-test questions administered before and after the webinar. The results showed a significant improvement, with the average pre-test score of 52.5 increasing to 85.3 in the post- test, indicating a gain of 32.8 points. In addition, the number of participants achieving perfect scores increased from 3 to 11, and almost all participants experienced score improvements. These findings indicate that webinars are effective in enhancing students’ knowledge of cybersecurity, particularly ransomware threats to the PDN.
