Analysis of the Administrative System of Correspondence (SA-ATAP) Using the SUS Method (Case Study: Medan High Religious Court)

Abstract

This research aims to evaluate the usability level of the Administrative System for Correspondence (SA-ATAP) at the Medan Religious High Court by utilizing the              System Usability Scale (SUS) method. The evaluation was conducted because ease of use is a crucial factor in enhancing the effectiveness of utilizing information systems for correspondence administration. This study applies a quantitative method with a descriptive design. Data were obtained through the SUS questionnaire, which consists of 10 statements with a five-point response scale. The research participants consisted of 15 individuals with experience using SA-ATAP. Data analysis was conducted by calculating the SUS score from each respondent, followed by calculating the average score to obtain an overview of the system's usability level. The research findings indicate that SA-ATAP achieved an average SUS score of 82.17 on a scale of 0 – 100. Based on the applied SUS interpretation criteria, this score falls into the acceptable category, with a grade B and the adjective rating of           Very Good. These findings suggest that overall, the respondents provided a favorable evaluation of the ease of use of SA-ATAP. This research presents empirical evidence regarding the usability level of the administrative letter management system in the context of religious courts. The measurement results can serve as a basis for system managers to maintain the already optimal usage elements and conduct further evaluations on aspects that still require improvement.
