In the early stages, a pre-survey involving 20 respondents using system usability scale (SUS) get an average score of 53.87, which gets Grade D and Acceptability Ranges level falls into the low category. The main problem obtained from observations, interviews, and questionnaires conducted to measure usability in e-HAC applications is the layout of this application that is not neat, so it is not user friendly. E-HAC application before the repair, many cause difficulties to the user, especially when filling out the form in creating the e-HAC application. After being done using the user-centered design method, the e-HAC application has improved its usability. Re-surveyed after making improvements with the same respondents in the Pre - survey, now sus score obtained by e-HAC application increased to 85.12 from 53.87, which means acceptability ranges that were originally Low to Acceptable. Moreover, for the Grade Scale, which was originally D into category B.
Although the usability results in e-HAC applications obtained in this study have improved, they are still not perfect and can be improved for future research. Additionally, due to the limited information from users who need further research, especially on observation to see the actual condition of using e-HAC application at the airport or port. Therefore, further evaluation and improvement is needed so that the score obtained can get the highest score in each category.
