Design and Implementation of an IoT-Based Application for Export-Import (EXIM) Document Management

International trade in the Export-Import (EXIM) sector is a key driver of global economic growth. However, EXIM document management still faces challenges such as data inconsistencies, input delays, and a lack of real-time visibility into document status. These issues result in shipping delays and increase operational costs. This research aims to develop an Internet of Things (IoT)-based EXIM application with an edge computing architecture optimized for local environments without reliance on cloud services. The development method used Rapid Application Development (RAD) through the stages of requirements analysis, interface design, module development, and iterative implementation involving user validation. This application integrates IoT devices such as scanners and thermal printers to automate document input and package tracking. Data is processed in real time by an Edge Gateway and synchronized to a local server, enabling document and logistics monitoring without an external internet connection. Implementation results show an increase in data input and reporting efficiency of up to 500 a 70% reduction in document errors, and an average processing time of 80% compared to manual systems. This approach provides a replicable solution for small to medium-sized logistics industries with limited infrastructure, while supporting digital transformation, operational reliability, and sustainable economic growth in the international trade sector.
