Pengujian Validitas dan Reliabilitas System Usability Scale (SUS) Untuk Perangkat Smartphone
System Usability Scale (SUS) Validity and Reliability Testing for Smartphone Devices
Abstract
To measure a more specific software based on smartphone cellular phones can be accepted by users, usability testing is carried out. To make a questionnaire that can be used to test the System Usability Scale (SUS) which is declared valid and reliable. The questionnaire was tested using an Expert Review and the Product-Moment Coefficient for validity testing, and Cronbach's Alpha for reliability testing. Based on the results of the tests carried out; there were 15 questionnaire items for the SUS test with all items declared valid by an Expert Review and Product-Moment Coefficient, and reliable with a Cronbach Alpha score of 0.835095216. Several studies related to making questionnaires for the SUS test where the language used is Indonesian and English with a total of 10 questions. This study itself provides another option for a questionnaire by adopting research that has been done by testing the validity and reliability to test software using the SUS test.
