Analysis and Design of Food Price Data Processing Information System

Abstract

Food prices have an important role in maintaining economic stability and public welfare, as price fluctuations can have a direct impact on purchasing power and inflation. However, the manual process of recording and reporting food price data at the Department of Agriculture and Food Security of Palu City results in inefficiencies, inaccuracies, and limited accessibility. This study presents the design and development of a web-based information system using the prototyping method, aimed at improving the efficiency of food price data management. The system was developed through iterative interaction between users and developers, and data collection was conducted through interviews, observations, and documentation. System functionality was tested using black-box testing, while usability was evaluated using the System Usability Scale (SUS). The system achieved an average SUS score of 74, which falls into the “Good” category, indicating that it is easy to use. Key features include daily price input, automatic average calculations, and report submission with approval workflows. This research contributes as the first implementation of a food price information system at the Agriculture and Food Security Office, offering a structured and user-oriented solution for institutional data processing and decision making.
