Evaluation of the Effectiveness of Smart Audio Input Selector & Volume Controller (SAISVC) Among Diploma in Mechanical Design Technology Students

Abstract— This study aims to evaluate the effectiveness of the Smart Audio Input Selector & Volume Controller (SAISVC) among Diploma in Mechanical Design Technology students at Besut Community College, Terengganu. The focus of the study is to determine the level of usability, functionality, and user satisfaction towards the developed prototype. A quantitative research approach was adopted using a questionnaire method involving a total of 44 respondents, consisting of 17 students from semester 2 and 27 students from semester 4. The research instrument utilized a Likert scale to measure students’ perceptions on aspects such as ease of use, audio stability, and volume control efficiency. The collected data were analysed using descriptive statistical methods, including mean and percentage. The findings indicate that the majority of respondents showed a high level of agreement across all evaluated constructs. The results demonstrate that the SAISVC prototype is effective and suitable to be used as a supporting tool in teaching and learning activities, particularly in laboratory and mobile audio applications.
