PAON usability testing using system usability scale

One of the important variables in developing software is users' satisfaction of the software. Hence, there is a need to measure users' satisfaction of the software's that have been developed. The measurement of the users' reactions covers some aspects such as users' satisfaction, ease of use, efficiency, and whether the systems that have been developed can meet the users' needs. This measurement is often called usability testing. It can be done using various instruments that have been developed by experts and communities in the field of computer. One of them is System Usability Scale (SUS). This article discusses an online peer assessment using usability testing. The instrument used was the usability scale system that was developed by John Brooke in 1986. The measurement using SUS yielded a mean score of 80.00. This mean score shows that the online peer assessment can be accepted and it can be categorized as grade B with Good rating. Hence, the online peer assessment is a feasible system.
