Abstract

Peningkatan jumlah pengguna internet dewasa ini membantu perkembangan media konektifitas internet. Dengan tingkat mobilitas yang tinggi, banyak orang lebih memilih media berbasis nirkabel daripada media berbasis kabel. Para penyedia layanan nirkabel ini menggunakan berbagai metode autentikasi, termasuk satu kunci, atau kata sandi, dan metode enkripsi seperti WEP dan WPA. Penggunaan autentikasi termasuk satu kunci, atau kata sandi untuk semua pengguna dirasa kurang aman dan kurang personal, Sehingga diperlukan cara lain yaitu dengan menggunakan satu kata sandi untuk satu pengguna. Pengguna harus memiliki akun dan password yang dibuat oleh pengelola hotspot sebelum dapat menggunakan layanan ini. Berdasarkan dari masalah tersebut diperlukan perancangan sistem berupa penggunaan halaman login saat pengguna menggunakan jaringan nirkabel di Universitas Siber Muhammadiyah dengan memanfaatkan fitur hostspot yang ada di Mikrotik, Hasil dari penelitian ini diharapkan ada hasil rancangan jaringan hotspot yang bisa digunakan sebagai referensi para administrator jaringan.

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

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.
