Abstract :
Waste is a serious problem that needs to be addressed in Indonesia. Data from the Banyumas
Regency National Waste Management Information System (SIPSN) shows that the district
produces daily waste generation of 536 tons in 2022. To overcome this problem, the government
and the community need to work together in waste management, especially because the
Purwokerto city area has limited land. to manage waste. In an effort to improve waste
management, the Banyumas district government launched the digital-based Salinmas (Banyumas
Online Waste) application program, which allows residents to buy and sell waste online. However,
this application experiences problems related to a user interface that is not user friendly, making it
difficult for users to operate it. Therefore, it is necessary to redesign the graphic appearance of the
Salinmas application using the User Centered Design (UCD) method in order to improve the user
experience and increase the effectiveness of the application. In the context of waste management,
the Salinmas application has great potential to help facilitate buying and selling transactions
waste efficiently. However, problems related to a user interface that is not user friendly can
prevent users from utilizing this application optimally. Therefore, redesigning the graphic display
of the Salinmas application using the User Centered Design (UCD) method is the right step to fix
this problem. By prioritizing user experience, it is hoped that the Salinmas application can become
easier to use and effective in supporting waste management in Banyumas.
