Abstract
One of the factors that influence the success of a website is usability. The higher the level of usability of a website, the more the website is accepted by users and vice versa. In the Regional Office of the Directorate General of Taxes of North Sulawesi, Central Sulawesi, Gorontalo, and North Maluku, there is an application called Office Stationery Procurement Management and Equipment Services (LALAMPA). LALAMPA is an application that aims to cut the duration of service and simplify the process of requesting office stationery, can display information on the availability of office stationery in real-time, and can monitor the distribution of office stationery. To determine the feasibility of the application offered for use, this research proposes measuring the usability level of the application using the System Usability Scale. The System Usability Scale has ten statements that serve as evaluation tools and consist of three assessment indicators, namely acceptability, grade scale, and adjective rating. Each statement serves as a measure of the usability level of the application. A questionnaire containing 10 statements from the System Usability Scale method was distributed to 25 respondents who are users of the LALAMPA application. The usability evaluation of the LALAMPA application using the System Usability Scale method concluded that the application received a B+ grade for usability because the SUS score was 78.4. The interpretation results of the approach based on the nature (Adjective), this LALAMPA application is included in the “Good” category, and the level of acceptability is included in the “Acceptable” category, which indicates that this application can be widely accepted by users.
