“…Pada awal percakapan, user diminta untuk memilih satu diantara tiga menu yaitu System Usability Scale (SUS) untuk mengetahui tingkat kelayakan dan kegunaan dari chatbot. System Usability Scale (SUS) yang diciptakan oleh John Brooke pada tahun 1986, merupakan salah satu metode yang dapat digunakan untuk mengukur persepsi kegunaan sebuah perangkat keras maupun perangkat lunak(Boyd, 2018). Responden kuesioner SUS berjumlah sepuluh orang yang merupakan pengguna sertifikat elektronik BsrE dan pengumpulan data dilakukan secara daring menggunakan kuesioner dari Google Forms.…”

Sejarah artikel:Balai Sertifikasi Elektronik (BSrE) as one of the Certificate Authorities in Indonesia has been released a desktop-based digital signing application, but one of the weaknesses of desktop applications is its low portability. BSrE has also released a digital signing application for mobile operating systems, but it is only intended for users of the Android operating system. The aim of this research is to develop a digital signing application with Telegram Bot platform, that can be used to sign electronic documents using X509 certificates wherever and whenever, and also it can be run on all operating system platforms. The research methodology is using Rapid Application Development (RAD) which consists of four stages, Requirements Planning, User Design, Construction and Cutover. The backend system of the bot is built using Java programming language, and integrated with the MySQL database as conversation sessions storage. There are three main functions of the designed system, sign, verify and setting. Signed documents also have been tested in several pdf reader applications and digital signatures can be recognized and validated. Bot can also verify documents signed by other applications. Testing uses a black-box method, the results of functional testing and non-functional testing show the system can run properly as expected in requirements planning. Evaluation using System Usability Scale (SUS) indicate that the system is suitable for use.

“…The researchers conducted a usability test on a web application and invited participants to complete a SuS score immediately after the test and then over the following two weeks. The latter two time points involved the user completing the SuS survey using their memory of their past user experience[20].…”

The System Usability Scale (SuS) survey is a widely respected tool for measuring usability. Generally, a SuS score is administered directly after a usability test to assess the usability and user experience of digital products. However, some researchers have used SuS as a survey as part of longitudinal ‘in the wild’ trials where SuS is often completed some period after the trial. The aim of this research was to determine if a participant’s memory of a product’s usability would change if a SuS survey was administered at different times after a test. Hence, we sought to understand if recalling the usability of a digital technology was affected by temporal bias or memory decay. This paper includes results and findings from two studies, study 1 involved evaluating a web application and study 2 involved evaluating a virtual learning environment. Collectively the two studies had 212 participants (n = 212). The findings conclude that there is no significant change of the user’s recollection of the usability of digital product as evidenced by an analysis of users who completed multiple SuS surveys over a short term period of 3 weeks or over an extended period of time of 6 months. RESEARCH HIGHLIGHTS The system usability scale is used to test for memory decay and temporal bias in judging the user experience of technologies at different time points. 212 participants took part in two studies ranging from 3 weeks to 6 months. There is no evidence that there is a temporal bias or memory decay when users complete a SuS survey at the two different time points of 3 weeks and 6 months.
