Inveo, a management information system for emissions inventory e-administration in Indonesia

Emissions inventory is a data collection of accounted amount of pollutants released into the atmosphere. Emissions inventory can be useful to monitor air pollution in an area. Many countries in the world have already developed a system to manage emission inventory, excluding Indonesia. We have developed Inveo, a management information system for emissions inventory in Indonesia. As an e-administration system, Inveo aims to facilitate the process of collecting and managing regional emissions inventory data which also providing data and information to the public. Requirement analysis in this paper is defined by doing surveys and analyzing existing works and researches. Point, area, and road emissions inventory sources are modeled as a point. Inveo can manage several emissions inventory data such as emissions, locations, roads, surveys, facilities, fuels, map legend bounds, and user accounts. This system provides data and information to the public and is visualized by emission map, graphics/charts, and comparison statistics. Inveo is tested using three methods: functional testing, usability testing using system usability scale, and visualization testing. Based on the test result, the system is already fulfilled functional requirements, usability aspects with a SUS score of 75 and fulfilled usability and user experience goal, and the visualization is understandable for the users.
