Mobile Application as Media Monitoring in the Agility Record System (ARS)

This paper discusses a proposed system for measuring athletic agility based on Internet of Things (IoT) technology. The problem with existing agility gauges is that they still use a stopwatch to measure time, and the existing tools only have a few pads and a short distance. The main objective of this paper is to propose the design of an agility measuring system that is simpler and has the ability to coordinate with more motion sensor nodes. This paper also presents the design results of activity diagrams, transaction databases, block diagrams, and hardware configurations of motion sensor nodes. The result of this research is an IoT-based agility measuring system using the ESP8266 module, allowing 253 or more pads to be coordinated. The activity diagram consists of three main actors, namely admin/tester (coach), tester trainer (observer), and athlete actor. In the database design of this IoT-based agility measuring system, it consists of 6 tables, namely three master tables and three transactional tables. The three master tables are the "athletes" table, the "mater_pad" table, the "test_scheme" table. Meanwhile, the three transactional tables are the "test_log" table, the "test_pad" table, the "test_agility" table.
