Evaluasi Penerimaan dan Usability Aplikasi SIBERGO Menggunakan Technology Acceptance Model dan SUS

Abstract

As a mobile academic information system, SIBERGO supports students in carrying out their daily campus routines. To find out both how usable the application is and how willing students are to adopt it, this study combines two complementary instruments — the System Usability Scale (SUS) and the Technology Acceptance Model (TAM). Responses were gathered from 257 student users through an online questionnaire, then processed via descriptive statistics, validity and reliability checks, Pearson correlation, and Partial Least Squares-Structural Equation Modeling (PLS-SEM). On the 0-100 SUS scale, the application averaged 57.97, a Marginal, D-grade result that points to usability still below what the industry generally considers acceptable. Under TAM, five of the six proposed paths were statistically significant (p<0.05); notably, Perceived Ease of Use (PEOU) drove both Perceived Usefulness (PU) and Attitude Toward Using (ATU) at coefficients of 0.598 and 0.455. The direct PU-to-Behavioral Intention (BI) path, by contrast, was not significant (coefficient 0.068; p=0.357), leaving ATU to act as a full mediator between the two. A subsequent correlation analysis found PEOU to be the construct most closely tied to SUS scores (r=0.589; p<0.001), reinforcing agreement between the two evaluation methods. In short, students find SIBERGO reasonably straightforward to learn, yet its broader usability — system stability and feature consistency above all — has room to improve before daily use can be considered optimal.
