While STIKes have a basic in the field of Health, STMIK has a basic in Information Technology. The policy taken by the Tri Putra Persada Horizon Education Foundation is to integrate business processes in the two high schools under its auspices. The purpose of the policy is to help implement the vision, mission and needs of STIKes and STMIK, one of which is improving public services. Good information technology governance is a top priority in supporting the implementation of public services [1]. The importance of digital information, such as the relationship between organizations and the public, cannot be separated from the demands in providing maximum service [7]. An information system that can integrate administrative data in all parts of the higher education is needed to represent the business processes of the two higher education institutions in the Tri Putra Persada Horizon Education Foundation. Information system is a combination of work procedures, information, people and information technology that is organized to achieve goals in an organization [2]. To integrate information technology between two higher educations, an enterprise architecture is needed that can be a reference in its implementation. Enterprise architecture is generally defined as models, documentation, and reusable items such as components, frameworks, objects and so on, which reflect an architecture as a whole [4]. Frameworks in enterprise architecture can be used to manage complex information systems and to align business processes and invested information technology [5]. In terms of enterprise architecture modelling, there are several methodologies that can be used, one of which is the TOGAF Framework. TOGAF or The Open Group Architecture Framework is an enterprise architecture framework that provides a comprehensive approach to the design, planning, implementation, and governance of information architecture [3]. The TOGAF chosen is TOGAF ADM, because TOGAF ADM is a method that can be adapted to all changes and needs during planning. This method can also be used as a guide or tool for planning, designing, developing and implementing information systems architecture for organizations [6]. In previous study using Enterprise Architecture Design Using TOGAF at ABC University conducted by Lestari Retnawati [8], focused on designing blue prints to get an overview of ICT strategies and developments in the world Research Article Open Access (CC–BY-SA) Abstract The use of information technology in the field of education is currently a top priority for managing academic and supporting activities. Tri Putra Persada Horizon Education Foundation which manages two high schools, namely the College of Health Sciences and the College of Information and Computer Management should face a challenge to align business strategy with information technology, and how to integrate all the parts involved in the business and represent it in an information system. To find out the business strategy and governance of information technology used at the Tri Putra Persada Horizon Education Foundation, an Enterprises Architecture Framework is needed, one of which is TOGAF ADM. The Enterprises Architecture design contained in TOGAF ADM includes a vision architecture that defines the vision of the company or agency, a mapped business architecture in the form of value chain analysis, an information system architecture in which there is a data architecture and application architecture and the last is technology architecture. This research produced an enterprise architecture design blueprint consisting of artifacts, in the form of catalogues, matrices, and diagrams based on the phases of TOGAF ADM. The result of the Enterprise Architecture design was an integrated information system recommendation and the technology architecture. The design is expected to be a reference in improving the quality of business and is expected to make it easier to achieve the business goals of the Tri Putra Persada Horizon Education Foundation.
