Today, there are often problems with consumers, such as high sales cancellation rates, consumers who are in arrears in payment of DP receivables, consumers who are in arrears in housing installments to banks as lenders, consumers who are in trouble, constrained mortgage documents and uncooperative consumers. PT Gerbang Duabelas needs to design an Enterprise Architecture that can filter prospective customers who have good and healthy prospects. Enterprise Architecture is an activity of organizing data that is used and produced by an organization that covers the business processes of the organization. The framework is used as a reference in designing enterprise architecture in this study is TOGAF ADM, with a focus on design in the information system architecture phase, namely the data architecture and application architecture. Key words: Enterprise Architecture, TOGAF ADM, System Information Architecture, Architecture Data, Architecture Technology.

INTRODUCTION At first the selection process for prospective consumers to become consumers of PT Gerbang Twelve housing was not too selective, consumers from various circles or financially disadvantaged people were still trying to be able to buy housing provided by PT Gerbang Duabelas, but over time many findings of fatal problems to consumers PT Gerbang Duabelas housing consumer, for example, starting from consumers who act or are not cooperative in collecting mortgage documents, consumers who are in arrears in down payment or down payment, so that there are also consumers who have credit agreements and installments in housing installments then defaults on installments, As a result, the developer lost trust by the http://iaeme.com/Home/journal/IJCIET 1 [email protected] Nilo Legowo, Wandi Aprianto bank as a credit provider because consumers from PT Gerbang Duabelas were in arrears in installments. Even more fatal is the rate of cancellation of home purchases is increasing. In the research conducted by Marlina and Nugroho in 2014, a business model, data model, application architecture model and IT infrastructure model for managing scientific journals in Indonesia produced 8 parameters of the TOGAF framework [9], while in the research conducted by Yunis and Surendro in 2010 concluded that TOGAF ADM is a method of developing enterprise architecture that can be tailored to needs, provided that the institution has clear rules and procedures about business processes to support the integrated information system development process [10] and on research conducted by Suoth & In 2014, Wijaya stated that the design of EA using the TOGAF ADM framework can provide an appropriate IS / IT environment in accordance with company conditions because TOGAF provides a flexible framework in the design of EA [11]. Therefore, it requires an enterprise architecture design that can filter consumers who are good prospects and financially healthy and cooperative so that the above problems can be minimized or eliminated. In this study, the TOGAF ADM framework will be used, the selection of TOGAF is based on several criteria for designing enterprise architecture, the first because of the requirement management that is not owned by other enterprise architecture frameworks. Management requirements are very useful to determine the requirements or requirements of an enterprise. Requirements are useful as input from each phase in TOGAF ADM in determining the target architecture so that the target architecture that is produced is in accordance with the requirements specified at the beginning. When associated with a case study at PT Gerbang Duabelas, the requirements as input are the needs of PT Gerbang Duabelas who want to be more selective in screening consumers. Furthermore, because of the TRM (Technical Reference Model), which is a reference to drawing artifact models to design enterprise architecture, then TOGAF ADM provides architectural principles to design enterprise architecture so that the design can be in accordance with the principles of enterprise architecture design. In addition to the selection of the TOGAF ADM framework because this framework focuses on the implementation cycle (ADM) and the detailed design process than other frameworks. TOGAF ADM is an EA framework that is suitable for use by enterprises that still does not have EA and the need for enterprise architecture development. TOGAF ADM states the clear vision and principle of how to develop enterprise architecture, the principle is used as a measure in assessing the success of the development of enterprise architecture by organizations (The Open Group, 2011). The TOGAF ADM Framework consists of 8 phases in the form of cycles, namely architecture vision, business architecture, information architecture, technology architecture, opportunities and solutions, migration planning, implementation governance, and architecture change management. This research will focus on designing consumer filtering information systems in the architecture vision, business architecture and technology architecture phases using the TOGAF ADM framework. The information system architecture phase has 2 parts, namely data architecture and application architecture, which is one of the stages in TOGAF ADM. In this business architecture defines the initial conditions of business architecture, determine the business model or desired business activity based on a business scenario. The importance of business architecture in an organization is to map the business processes that exist in the company. Technology architecture is the fourth phase of the TOGAF ADM framework. The importance of technology architecture in organizations is to map the hardware requirements of the application system, allowing identification of hardware that can be shared and allows identification of the integration mechanism between interconnected application system components. Designing Business Architecture and Technology Architecture is needed at PT http://iaeme.com/Home/journal/IJCIET 2 [email protected] Enterprise Architecture Analysis and Designing to Support the Filtering Process Consumer at Real Estate Company Gerbang Duabelas to be able to help PT Gerbang Duabelas in developing a consumer screening system that is in line with PT Gerbang Duabelas business strategy by providing guidance that can be the basis for the development and development of consumer screening systems at PT Gerbang Duabelas. 2. THEORETICAL BASIS 2.1. Enterprise Architecture Enterprise definition is a collection of organizations that have a set of general goals and / or goals. An enterprise can be a government institution, an entire company, a division of corporation, a department, or a chain of organizations that is geographically separated, linked by ownership of the same company. The term "enterprise" in the context of "enterprise architecture" can be used to show the enterprise as a whole, covering all its information systems, and a specific domain in the organization [1]. The architectural definition used in the ANSI / IEEE Std standard 1471-2000 is a fundamental organization of a system, inherent in its components, relationships with one another and its environment, and the arrangement of design principles and their evolution. Benefits of Enterprise Architecture Provide a mechanism that allows communication about EA elements between business and IT organizations and the functioning of the enterprise Generating centralized, stable information and improving consistency, thoroughness, timeliness, integrity, quality, availability, access, and sharing of information managed across the enterprise Quality and timely information provided by EAS makes it easy for enterprise to respond to the power of change and make better decisions Allows organizations to reduce duplication in information Linking IT to organizational missions Improve interoperability and accelerate legacy system integration, migration and new systems Allows dexterity Reduce costs or achieve economical scale by providing mechanisms for sharing services across the enterprise Improve security Reduce technical risks Focus is on technology usage strategies to manage data as assets Elements of Enterprise Architecture According to Dirk Maurer and Patrick Buch (2007), EA emerged as a key tool for documenting, analyzing, and managing complex structures on an enterprise, which in turn formed part of a single architectural framework Describes the information required for a complete architecture. EAS elements in general, consisting of
