Abstract

This research delves into vulnerability testing of Learning Management Systems (LMS) using penetration methods, aiming to enhance the security resilience of LMS platforms against cyber threats. By employing a structured penetration testing framework encompassing stages such as reconnaissance, scanning, gaining access, maintaining access, and covering tracks, the study seeks to identify and address potential vulnerabilities within LMS systems. The research contributes to fortifying LMS platforms by simulating attacks and evaluating system weaknesses to provide insights for effective security enhancements

Abstract

Penelitian ini mengeksplorasi dampak penggunaan framework Next.js terhadap performa frontend website. Next.js, dengan fitur-fitur seperti server-side rendering (SSR) dan static site generation (SSG), menawarkan potensi peningkatan signifikan dalam kecepatan pemuatan halaman dan pengalaman pengguna. Studi ini membandingkan performa website yang dibangun dengan Next.js terhadap website yang dibangun dengan pendekatan tradisional (menggunakan Bootstrap), mengukur metrik kunci seperti waktu pemuatan halaman, ukuran file, dan skor Lighthouse. Hasil penelitian menunjukkan peningkatan yang signifikan sebesar 62.5% dalam performa website Next.js. Temuan ini memberikan bukti empiris tentang manfaat Next.js dalam pengembangan website yang berfokus pada performa.

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.
