Perceived Effectiveness Of Whatsapp Usage Among Staff Of The Department Of Mechanical Engineering, Politeknik Kota Bharu

This study was conducted to evaluate the perceived effectiveness of WhatsApp usage among staff at the Department of Mechanical Engineering, Politeknik Kota Bharu. In the current era of communication technology, instant messaging applications have become an important medium for delivering information quickly and efficiently, particularly within higher education institutions. This study adopted a quantitative approach by distributing a structured five-point Likert scale questionnaire to a sample of 30 academic and support staff selected via simple random sampling from a total departmental population of 65 personnel. The collected data were analyzed using descriptive statistical methods, including percentages, mean scores, and standard deviations. The findings indicate that WhatsApp usage contributes to a positive perception of internal communication within the department. Information delivery has become faster, easier, and more organized, as evidenced by a high overall mean score of 4.35 for the level of usage and 4.43 for perceived effectiveness, thereby enabling staff to perform their daily tasks more efficiently. Therefore, this study suggests that clear operational guidelines for digital communication applications should be established to ensure a more structured, professional, and productive use of WhatsApp among institutional staff.
