The findings reveal that IT students demonstrated significantly higher cybersecurity knowledge (m = 4.21, sd = 0.67) and practices (m = 4.07, sd = 0.66) compared to non-IT students (knowledge: m = 3.26, sd = 0.63; practices: m = 3.23, sd = 0.74), with statistical tests confirming these differences as significant (knowledge: u = 4221.000, z = -10.847, p < 0.001; practices: u = 5565.500, z = -9.453, p < 0.001). These results indicate that academic discipline strongly influences cybersecurity awareness, with IT students benefiting from technical exposure while non-IT students display notable gaps. The study underscores the need to integrate cybersecurity education and practical training into non- IT curricula to foster a more security-conscious academic environment.

A Survey on Satisfaction and Effectiveness of the School Holiday Program at Kolej Komuniti Ledang: A Study on Implementation and Academic Skill Enhancement of Students
The School Holiday Program conducted at Kolej Komuniti Ledang aimed to enhance students’ knowledge and confidence in Mathematics and Science through short structured courses. This study evaluated the satisfaction and effectiveness of the program in improving academic skills among primary and secondary school students. A total of 189 participants from Tangkak and Muar joined courses such as Syoknya Sains, Bijak Algebra, Matematik Persediaan Tingkatan 1, and Bijak Pecahan. A quantitative survey design was employed using pre- and post-program evaluation forms. The instrument covered two dimensions: Course Implementation (content delivery, teaching methods, suitability of venue, and time allocation) and Course Effectiveness (knowledge, skills, confidence, and career relevance). Findings indicated high participant satisfaction, particularly in content delivery (M = 3.66) and course organization (M = 3.63). Paired-samples t-tests showed significant improvements: knowledge increased by 1.413 mean points (≈60.6%), while skills improved by 1.381 mean points (≈63.6%), with p < 0.001 for both. These results confirm the program’s effectiveness in strengthening both cognitive and affective learning dimensions. Overall, the program successfully achieved its objectives by enhancing students’ knowledge, skills, and confidence, while providing positive exposure to STEM-based learning during school holidays. The study highlights the importance of interactive and student-centered approaches in community-based learning programs and recommends replication of such initiatives in other regions.
