ABSTRACT
Plasa Telkom Penajam is an outlet or place of service belonging to PT.
Telekomunikasi Indonesia, Tbk (Telkom) which is fully managed by TELKOM
and or in collaboration with PARTNER, provided to serve customers, prospective
customers, users of Telkom services and or TELKOM Group services who wish to
be served online. directly (face to face) with various possible backgrounds or
causes, both regarding the need for all information related to Telkom's products
and services, as well as to fulfill basic needs themselves. From its business
processes, Plasa Telkom Penajam has several problems that have the potential to
disrupt its business activities, one of the problems is the occurrence of errors in the
management of outgoing modem data and frequent errors in recording, due to the
absence of an integrated information system to support activities within the
company. In designing the EA at Plasa Telkom Penajam using The Open Group
Architecture Framework (TOGAF) and the Architecture Development Method
(ADM) which have been limited and consist of several stages, namely the
preliminary phase, architectural vision and business architecture. This study aims
to identify business processes and create IS/IT blueprints. The result of this
research is the design of Enterprise Architecture in order to support its business
processes and build an information system to meet the needs of business strategy
activities that produce the main blueprints of TOGAF, namely business
architecture and application architecture.
INTRODUCTION
The role of Information Systems and Information Technology (IS/IT) in carrying out
business processes in the current information age is very necessary. IS/IT has several
important roles in an organization, among others, to be a means to assist organizations in
realizing integration between management and operations, improve service quality to
consumers, and assist in the decision-making process (Mengcheng & Tuure, 2022).
The development of Information Technology in business processes, will require
organizations to make changes with the implementation of a mature business plan, so that it
can run according to plan. In order for a business plan to run well, a tool is needed that can be
used to provide a basic organizational structure for the company as a whole and describe the
relationship between the aspects in it. The tool in question is Enterprise Architecture (EA)
(Alzoubi & Gill, 2022).
Enterprise is one of the most complex man-made systems consisting of human,
political, social, software, hardware and technology components. An enterprise can be a
government agency or a chain of interconnected but geographically distant organizations.
PT Telekomunikasi Indonesia, Tbk is a provider of InfoComm services, fixed
wireline and fixed wireless, cellular telephone, data and internet services, as well as the
largest network and interconnection in Indonesia, both directly and through subsidiaries
(Sugianto, n.d.).

Data collection for goods and services at Plasa Telkom Penajam, was carried out at
the Warehouse Admin Staff section with the current system not utilizing technology and
computer systems optimally. In the data collection of goods, it is still done manually by
recording every item that has been issued by the Warehouse to the technician to be attached
to the customer who installs Indihome. It is not known for sure whether the item has been
paired with the customer or not. There needs to be a system that makes it easier for the
Warehouse Admin Staff to find out more easily whether the item has been installed by a
technician to the customer or not (Huang, 2022).
Enterprise Architecture (EA) is the planning, design and management of IS/IT
Infrastructure and is able to integrate IS/IT in an architecture (Rouhani, Mahrin, Nikpay, &
Nikfard, 2013). Enterprise Architecture is an organizational blueprint that defines the
business, information and technology used to achieve the organization's mission. Enterprise
architecture is a collection of plausible principles, methods and models used to design and
realize an enterprise organizational structure, organizational structure, information system
and infrastructure system. EA serves as a provider of blueprints or basic frameworks
(blueprints) for the system during the process of the system development project. Various
paradigms and methods can be used in EA design, including Zachman, TOGAF, FEA and
Gartner.
TOGAF (The Open Group Architecture Framework) is a framework and method
development for Enterprise Architecture that is used by enterprise architects to design, plan,
implement, and manage enterprise architecture in detail and detail (Sari & Anggraeni, 2022).
The togaf framework is a method that can perform enterprise architecture, enterprise
architecture is a useful tool for developing the range of any existing architecture (Prawira,
Azizah, & Astuti, 2018). TOGAF is a guide to stages and principles that provide flexibility
and choose the modeling technique used and is a combined guide from various architectural
development frameworks (FEAF, TEAF, DoDAF, etc.) (Karunia, 2015).
Several previous studies were used as references in writing, such as the Final Project
compiled by Elfira Rossa in 2020 with the title "Designing Enterprise Architecture Using the
TOGAF ADM Framework". This research produces an IS/IT blueprint from the main
architecture in TOGAF ADM, namely business architecture, data architecture, application
architecture and technology architecture. The IS/IT blueprint can be used as a guide in
developing IS/IT at PT. Astragraphia Tbk Pekanbaru Branch. This research uses The Open
Group Framework (TOGAF) and the Architecture Development Method (ADM) architecture
development method (Hermawan & Sumitra, 2019). This research is limited to the
preliminary phase, architectural vision, business architecture, information systems
architecture, and technology architecture. This study does not discuss the phases of
governance of opportunities and solutions, migration planning, implementation and
management of architectural change (Rossa Elfira, 2020).
Furthermore, the Thesis compiled by Ines Putri Karunia in 2015 with the title
"Enterprise Design architecture Using TOGAF Architecture Development Method”. This
research resulted in enterprise architecture planning using the TOGAF 9 framework to align
activity strategies in the form of blueprints from the main architecture in TOGAF, namely
business architecture, application architecture, data architecture and application architecture.
This research is limited to the preliminary phase, vision architecture, business architecture,
information systems architecture, technology architecture, opportunities and solutions, and
migration planning.
The purpose of this research is to plan the business architecture at Plasa Telkom
Penajam.

METHOD RESEARCH
The research method used in this study is a qualitative descriptive method. The type
of data used in this study is qualitative data, which is categorized into two types, namely
primary data and secondary data. Sources of data obtained through library research
techniques (library study) which refers to sources available both online and offline such as:
scientific journals, books and news sourced from trusted sources. These sources are collected
based on discussion and linked from one information to another. Data collection techniques
used in this study were observation, interviews and research. This data is analyzed and then
conclusions are drawn.
Method of collecting data
The data collection method is used by the author in order to assist in collecting the
necessary data and information from Plasa Telkom Penajam to obtain the correct description
of the material for discussion. The data collection method used is the Observation Method
and the Interview Method. Observation is a data collection technique that is carried out
through an observation, accompanied by notes on the state or behavior of the target object
(Fatoni, 2011). The purpose of the observation is to conduct a direct review or direct
observation related to the activities and business processes at Plasa Telkom Penajam. The
author made observations in October 2020 which took place on Jl. KM Province. 2 RT. 026,
North Paser Sharpening. Interviews are a form of direct communication between researchers
and respondents, the interview aims to obtain information about the business activities carried
out by Plasa Telkom Penajam through direct interviews with Warehouse Admin Plasa
Telkom Penajam, Mahdalena and Tyas Mugiyanto. In this case, interviews were conducted
with parties who are considered to know the ins and outs which aim to obtain data and
information related to the ongoing business process of procurement of goods and information
technology support at Plasa Telkom Penajam.
Enterprise Architecture Planning Method
The method used by the author in planning enterprise architecture is TOGAF ADM,
TOGAF Architecture Development Method (ADM) is a flexible method that can anticipate
various kinds of modeling techniques used in the design, because this method can be adapted
to changes and needs during the design. Surendro, 2009). The TOGAF ADM used consists of
a preliminary phase, architecture vision, and business architecture. and Tools used in
enterprise architecture planning are Principle Catalog, Value Chain.

RESULT AND DISCUSSION
Preliminary Phase
Preliminary phase (preparation stage) is the initial stage of preparation for enterprise
architecture design (Suryadi & Andry, 2017), this stage is carried out so that the EA
modeling process can be well directed. This phase begins with identifying and establishing
EA principles consisting of applications and technology architectures that are in accordance
with the needs of Plasa TELKOM Penajam. The preliminary phase consists of EA design
principles.
The principles of Enterprise Architecture (EA) design are part of the Information
Systems and Information Technology (IS/IT) policy at Plasa Telkom Penajam which will
affect the EA design process. These principles can be useful as a reference in making
Information Technology architecture decisions, determining the structure and composition of
architectural components, determining criteria for selecting technologies and products to be
used, as well as in architectural design and implementation (Herrington, McKenney, Reeves,
& Oliver, 2007). The principles that will be used as a design reference will be explained in

Phase A : Architecture Vision
Value Chain is a series of activities carried out by a company focused on a particular
industry performing to provide a valuable product or service to the market. Value Chain
describes a way to view a company as a chain of activities that transform inputs into outputs
that are of value to customers, Value chain is expanded to describe a series of organizational
activities that create, deliver, and capture value in each process, starting with the processing
of raw materials to the finished product in the hands of the customer. Value chain
management can be defined as the process of managing all sequences of integrated activities

and information to transfer value along the entire supply chain (Simatupang, Piboonrungroj,
& Williams, 2017).
Value Chain Analysis, is a tool to understand the value chain that forms a product.
This value chain comes from the activities carried out, from raw materials to the hands of
consumers, including after-sales service. Value chain analysis aims to group all activities in
Plasa Telkom Penajam (Cagliano, De Marco, Grimaldi, & Rafele, 2012). The grouping of
activities in the value chain is divided into two, namely the main and supporting activities.

Phase B : Business Architecture
The business architecture design is designed in the form of BPMN diagrams for each
activity at Plasa Telkom Penajam, namely procurement of goods, receipts, maintenance,
sales, expenses and finances with the aim of making it easier for users to understand the
business architecture design (Barros & Guezada, 2014).

The procurement department makes a purchase order after recording the minimum
stock report. Then after the supplier receives the purchase order, it will prepare the goods.
After the goods have been prepared, the goods will be directly sent by the courier to be
received by the warehouse who made the purchase order.
Reception
Figure 4. Acceptance Business Architecture Design
In this section, the warehouse receives the goods that have been sent by the courier,
then checks, records and reports the incoming goods data. After receiving the report, the
supplier will provide data on the number of items sent for verification by the warehouse on a
pre-existing application, if it does not match the number of items that have arrived, the
supplier will resend the shortage.
Maintenance
Figure 5. Maintenance Business Architecture Design
The maintenance department only performs cleaning maintenance and calculates the
stock of goods.
Sale
Figure 6. Sales Business Architecture Design
In the sales department, marketing makes an offer to provide product info to
customers, if the customer is interested it will be asked for data for later registration after the
data is checked. To register, the marketing party will first login to the application, then the
customer will make a payment. After the payment is confirmed, the marketing party will
report the order and record sales data.

Expenditure
Figure 7. Expenditure Business Architecture Design
The design of the expenditure business architecture will use the application.
Technicians and warehouse staff involved in the application must first log in. The technician
will ask for the modem needed to be checked for inventory by the warehouse staff, if
available, the SN modem will be inputted into the application along with the data of the
technician who received it for verification by the person concerned. After verifying, the
technician will report the customer data to which the modem will be paired and input the data
according to the SN of the modem being used.
Finance
Figure 8. Financial Business Architecture Design
In the finance section, income recording and financial accounting management are
carried out to then make financial accounting reports and make deposits to the central party.
CONCLUSION
Value chain analysis aims to group all activities at Plasa Telkom Penajam. The
grouping of activities in the value chain is divided into two, namely main activities and
supporting activities. The business architecture design is designed in the form of a BPMN
diagram for each activity at Plasa Telkom Penajam namely procurement of goods, receipts,
maintenance, sales, expenses and finances with the aim of making it easier for users to
understand business architectural designs. From the identification of business processes at
Plasa Telkom Penajam resulted in a solution and business process design that is simpler and
has been adapted to future business needs and the need for facilities to support IS/IT planning
