ABSTRACT
The use of information technology that is aligned with the company's goals will be
achieved if supported by a good governance planning system. Therefore, to develop
information technology can use the Enterprise Architecture approach as a guideline
or blueprint in the development of information technology. The XYZ company is an oil
palm plantation company that develops information technology services to support the
company's business operations. In order for the purpose of developing XYZ company
information technology services in line with the company's vision, mission and
objectives, an appropriate framework is needed in preparing strategic planning. This
study aims to provide recommendations for designing IT blueprints using the
Enterprise Architecture TOGAF framework for the development of information
technology that can be applied in XYZ companies.

1. INTRODUCTION
The XYZ company is an oil palm plantation company with its main products, crude palm oil
(CPO) and palm kernel (PK). The company utilizes information technology (IT) services by
implementing an Enterprise Resources Planning (ERP) system, namely System Analysis and
Program Development (SAP) as the main system. In its application not all SAP modules are
used, because some SAP system modules are not in accordance with the company's business
processes and SAP user license costs are relatively expensive, so it becomes a consideration

not to use all SAP modules. As a result, the application of information technology is still not
optimal and affects the company's business service activities.
At present the company has its own IT infrastructure to support information system
services. In carrying out its functions, IT infrastructure has experienced service disruption for
741 hours in the period 2017-2018. So that it affects the information system services.
Of the several constraints that exist, the company does not have strategic planning, so it
has an impact on IT services. In order for the purpose of developing the company's
information technology services in line with the company's vision, mission and objectives,
strategic planning is needed.
Enterprise Architecture is one method that can be used as a guide in developing
information technology effectively and efficiently. Enterprise Architecture can be defined as a
blueprint [4], to place optimal resources and concrete targets in the IT environment as the last
support of business functions. This study aims to provide recommendations for designing IT
blueprints using the Enterprise Architecture TOGAF framework for the development of
information technology that can be applied in XYZ companies.
2. LITERATURE REVIEW
2.1. Information Systems Definition
An information system can be an organized combination consisting of users, hardware,
software, communication networks, data sources and procedure policies that store, retrieve,
change, and disseminate information within an organization. Humans rely on information
systems to communicate with each other using various physical devices, hardware,
instructions and procedures for processing information software, network communication
channels or data sources [5].
An information system collects, processes, stores, analyzes and disseminates information
for specific purposes [6].
Information systems are interrelated components and work together to collect, process,
store and disseminate information to support decision making, coordination, control, analysis,
and visualization in an organization [3].
An information system is collecting, processing, storing, analyzing, and disseminating
information for certain purposes [10].
Information system is a system that brings together four critical components to collect,
process, manage, analyze, and distribute information; the four components are human,
technology, process and data [12].
2.2. Information Technology Definition
The collection of computing systems used by organizations is called information technology.
Information technology in its narrow definition refers to the technological side of an
information system. Often the term information technology is used interchangeably with
information systems. In his book the term information technology in the broad sense to
describe a collection of organizational information systems, users, and management who
oversee them. For the most part, the term information technology and information systems are
considered the same thing [11].
Information technology is a general term that describes any technology that helps produce,
manipulate, store, communicate, and disseminate information [13].

2.3. Information Technology Infrastructure Definition
Understanding information technology infrastructure is a shared technology resource that
provides a platform for enterprise-specific information system applications. IT infrastructure
includes investments in hardware, software, and services such as consulting, education and
training [3].
Some characteristics of information technology infrastructure [7], As follows:
1. Physically connected with and as the foundation of the structure above.
2. More permanent and static than the structure it supports.
3. Broader than the structure above in use.
4. Is a support service.
5. Apart from the structure that it supports in terms of the life cycle.
2.4. Enterprise Architecture Definition
Enterprise is a collection of organizations that have a series of general objectives. For
example, government agencies, divisions within a company, a single department or a chain of
organizations that are geographically separated and linked together for joint ownership. The
term company in the context of architecture is used to show the entire company, which
includes all information services, technology, infrastructure and certain domains within the
company [9].
The definition of architecture is the fundamental organization of a system, which is
embodied in its components, their relationships with each other and the environment and the
principles that govern the design and evolution of it [1].
Description of Enterprise Architecture is all coherent principles, methods and models used
in the design and realization of corporate organizational structures, business processes,
information systems, and infrastructure. Enterprise architecture captures the essence of
business, IT, and its evolution. The idea is that important things are far more stable than
specific solutions found for the problem at hand. Therefore, architecture helps in maintaining
the essence of business, while still allowing maximum flexibility and adaptivity according to
[2].
2.5. Framework Definition
A framework is a structure for content or processes that can be used as a tool for structuring
thoughts, ensuring consistency and completeness [2].
The selection of the right framework can facilitate the implementation of information
technology architectures in organizations [8]. Many frameworks have the same main purpose,
namely collaborating the strengths between:
1. Aspects of a business plan: goals, vision, strategies and principles of governance.
2. Operational aspects of the business: business terms, organizational structure,
processes and data.
3. Aspects of automation: information systems and databases.
4. Aspects of business determinants of technological infrastructure such as
computers, operating systems, and networks.
The Open Group Architecture Framework (TOGAF) is a detailed method framework and
supporting tools for developing enterprise architecture. TOGAF can be used freely by any
organization that wants to develop company architecture.

Designing It Blueprint with Togaf For Information Technology Development
In TOGAF there are methods used to design an architecture called the Architecture
Development Method (ADM). ADM can be used as a guide for modeling enterprise
architecture development. ADM contains the stages of activity divided in phases that have
been tested in architectural development. The activities contained in ADM include: the
creation of an architectural framework, building the contents and components of the
architecture, the process of migration from the current system and architectural governance to
be built.
3. RESEARCH METHODOLOGY
The research method is a case study that provides reviews of enterprise architecture design
activities based on company problems. The research phase, starting from determining the
problem, literature study and data collection. Then the IT blueprint design is carried out using
the TOGAF ADM framework. The results of the IT blueprint design, in the form of a
blueprint for the development of information technology. Figure 1 is the phase of the research
method.

4.6. Technology Architecture
Technology architecture addresses the needs of technology including network services,
security services, infrastructure, data services, application services, and support services.
4.6.1. Baseline Technology Architecture
Based on data collection conducted through analysis of company documents and interviews
with the IT Infrastructure Manager. Explanation of current technology architecture:

The data center used by the company is its own data center with a Tier 1 classification.
The location is inside the company's office which is managed independently and does not
have a disasater recovery center (DRC).
Server hardware used by virtual machine devices.
Storage used is a type of Storage Area Network (SAN), currently storage capacity for
prosuction database backups is not proportional to the capacity of database production.
Network hardware used is in table 7. In the table the number of core switches as main
switches is only 1 unit and for firewall devices also 1 unit, so there is no backup device.
Network topology that is used to connect between the head office and the site. The topology
used only has 1 unit of firewall device that connects the server Demilitarized Zone (DMZ)
area. Whereas the Farm Server area does not use firewall devices.The data network service
used has 2 types of connections between head office and site, namely satellite and terrestrial
connections.
Based on current technology security identification analysis, including:
1. There is no control access for access to infrastructure and information systems.
2. There is no management control access related to network users. and monitoring
log.
3. There is only one layer of firewall that limits access to data servers and application
servers from the internet or outside networks.
4. There is no system for preventing intrusion to maintain data confidentiality.

4.6.2. Target Technology Architecture
This stage is done by identifying the technological architecture needed to support the
application architecture. The following is an explanation of the target technology architecture.
The data center used by the company is a data center with Tier 1 classification, meaning
that IT equipment is served by one distribution channel (non-redundat), or one uplink per one
server. Thus, the availability of data center technology services is likely to experience a lot of
downtime. For this reason, it is necessary to increase the classification to Tier 2 by adding

Maulana Ibrohim, and Abba Suganda Girsang
redundant components by adding backup resources equipped with generators in preparation
for a power outage. The current data center does not yet have a disaster recovery center
(DRC), so if the datacenter function occurs, the call is not redundant, so it is necessary to
procure the DRC.
With the addition of applications, also requires appropriate resources to use, so that the
server performance is maintained. For this reason, it is necessary to procure new server
devices for the backup server to maintain service availability.
Data storage media every day diminishes, for that additional storage is needed based on
the needs needed. Currently the storage capacity for backup database production is only 8
terabytes while the database production capacity is 10 terabytes, so it is not proportional to the
amount of data to be backed up.
The condition of the network hardware used by the company today, there is still Single
Point of Failure, meaning that it still has a dependency on a function, if the function fails then
the entire system does not work. In table 7network hardware, the core switch device as the
main switch is only 1 unit and for the firewall device is also 1 unit, so there is no backup
device. For this reason, a redundant or a backup device is needed in preparation for the core
switch and firewall functions to occur.
The network topology used only has 1 unit of firewall device that connects the server
Demilitarized Zone (DMZ) area. While the Server Farm area does not use firewall devices, so
it does not have layered security. This allows an attack and disrupts the performance of Server
Farm as the company's operational application server services. The internet site service
facility is currently being distributed from the Jakarta head office, thus disrupting application
service lines, thereby reducing the speed of business application usage performance. For this
reason, it is necessary to separate the internet data path and application data path.
The data network service used by the company has 2 types of connections between head
office and site, namely satellite and terrestrial connections. Differences in satellite
connections and teriserial data transfer rates. The use of satellite connections data
transmission speeds is slower than terrestrial. For this reason, a connection standard is needed
so that data transmission stability is guaranteed by using a terrestrial network connection.
Based on current technological security analysis.Services used to support administration
of access rights related to information and monitoring in the form of:Identity management,
authorization, authentication, and access control management, control logging and log
management, auditing ability, Control monitoring and event management, Data encryption /
decryption control and key management controls, physical access, intrusion detection, and
surveillance controls.
5. CONCLUSION
This study focuses on enterprise architecture recommendations as a blueprint for the
development of XYZ company information technology, which consists of business asset
model recommendations, information system architecture and technology architecture.
The recommended business architecture model is a subprocess that was previously done
manually can be done in a system, so that it can reduce the manual workload and support the
business needs of the XYZ company optimally.
The recommended information system architecture model is modular application
development, so that the main SAP system applications are still used. Business functions that
are not yet available on the SAP system can be developed with integrated support
applications, or by developing new partially replace submodules from SAP submodules, so as
to reduce the cost of user licenses in SAP without reducing existing business functions.

The recommended technology architecture model is that the use of technology is still
being used, but it is necessary to add and update the quality of technology to optimize the
company's information technology services.
Designing IT blueprint using TOGAF ADM can be used as a reference to provide
integrated business, data, information and technology recommendations to optimize the
development of information technology.
