Abstract :
High School (SMA) Negeri 3 Jambi City is one of the senior secondary education institutions in Jambi City. At SMA Negeri 3 Jambi City there are several activities carried out conventionally and do not yet have an integrated information system. This causes the data and information needed to be not timely and difficult to access data and information. This study aims to integrate systems that have not been integrated. To integrate the system, an information system enterprise architecture plan was made using the TOGAF ADM framework. The TOGAF ADM stages carried out in this research are starting from the Preliminary Phase to Phase D Technology Architecture. The guide consists of business architecture, data architecture, application architecture that produces 7 old applications and 13 proposed applications that have been integrated with old applications, and technology architecture that can be used as a reference in further development for systems that can be applied to SMA Negeri 3 Kota. Jambi. Planning for enterprise architecture information systems produces a proposal in the form of a blueprint containing network topology descriptions of the technology planning process that will be applied to SMA Negeri 3 Jambi City which can be used as a reference in planning enterprise architecture.
