Development of e-Government in Indonesia continues to roll and run in every government agency, both in centralrngovernment and local government. Implementation of e-Government means that there are government's efforts to build andrnimprove the quality of public services and internal operations in each regional apparatus organization effectively andrnefficiently. These activities inline with one of the bureaucracy reform mission, that is the modernization of governmentrnbureaucracy through the using of information and communication technology optimization to support bureaucracy reformrnvision and the creation of good governance. The development and implementation of e-Government currently mostlyrnimplemented by each regional apparatus organization. This condition makes it difficult to exchange data and informationrnrelated to multisectoral activities due to data and information spread across various databases from different applications,rnplatform, environment and architecture without good documentation. In preparation for arranging the e-Governmentrnarchitecture, we will use The Open Group Architecture Framework - Architecture Development Method as an enterprisernarchitecture framework. The purpose of this research is to study and conceptualize e-Government interoperability andrnintegration solutions of all existing applications and providing some model documents such as e-Government ArchitecturernVision, Integrated Business Model References Architecture, and Integrated Data Model References Architecture.
