Abstract

This research focuses on the imbalance between supply and demand in the tapioca industry, especially on the scale of Small and Medium Industries (SMI). Such challenges involve price fluctuations and lack of efficiency in determining the optimal production amount. Using fuzzy logic as an artificial intelligence method, this research aims to develop a system for predicting the optimal amount of tapioca production that can increase efficiency, reduce waste of raw materials and energy, and stabilize prices. The data used in this study was obtained through interviews with resource persons who are involved in the field of tapioca SMI. Furthermore, the data was processed using the Mamdani Fuzzy Inference System method. The results showed that in the case of production when demand is 400 kg and cassava availability is 2000 kg, the optimal production amount of tapioca is 630 kg. This value is also consistent when proven using the Matlab R2015a application. This shows that the model can be relied upon in determining the decision on the amount of tapioca production by considering demand factors and raw material availability.

Abstract

This research aims to design the user interface of the HewanKu application using the User Centered Design (UCD) method, in order to improve user experience in buying and selling livestock transactions. UCD is applied to ensure that the design of the application interface is in accordance with user needs and preferences. The research method involves the stages of user needs analysis, design, prototype testing, and design iteration based on user feedback. Application testing was conducted using a Black Box Testing approach to ensure that the application functions according to specifications without navigation errors or feature failures. The results showed that the application of UCD succeeded in producing a more intuitive and efficient interface, as well as increasing user trust and satisfaction in transactions. The conclusion of this research is that the combination of UCD and Black Box Testing is effective in creating an application that is easier to use and reliable to support livestock buying and selling transactions.

Abstract

This study aims to evaluate the application of the User-Centered Design (UCD) approach in designing the user interface (UI) and user experience (UX) of the CarbonArea website, which provides information on the impact of carbon dioxide (CO2) on food security. The research methodology included interviews with potential users, a literature review, as well as iterative stages of UCD, including understanding the context of use, identifying user needs, designing a solution, and conducting a design evaluation. The interview results revealed that users wanted interactive features such as maps and graphs for real-time monitoring of CO2 levels. The application of UCD proved effective in creating a design that meets user needs, while improving user experience and website attractiveness.
