The Integrated Information System Implementation Strategy in Korlantas Polri Based on the Zachman Framework Approach

Traffic Police Corps (Korlantas Polri) is the executor of the main duties of the Indonesian National Police in the areas of security, safety, order and smooth traffic. Korlantas has some information that can be accessed by the public, namely information on congestion, accidents, traffic flow status, vital objects, road conditions, data and visual images from CCTV, public service conditions, and traffic infrastructure. However, these data are stand alone and not integrated with their respective applications and systems. The purpose of this study is to analyze the strategy for implementing an integrated information system at Korlantas Polri and what steps can be taken to integrate the existing system. This study uses the Zachman Framework which is adapted to Enterprise Architecture Planning (EAP) and qualitative data collection methods by interviewing stakeholders who are involved in managing information systems at Korlantas Polri. The results obtained are the need for a data warehouse by implementing an AI based integrated database system, Geospatial Information System, Business Intelligence and DSS, as well as Smart Visualization to visualize existing data. Then standardize the need for equipment and support for improving the ability of personnel in the IT field.


Introduction
Information Technology (IT) refers to a set of technological tools and resources employed to oversee, process, and manipulate data with the objective of generating relevant information [1].Utilizing IT is a prolonged investment for any organization, government included, to enhance the efficiency and efficacy of the operations it performs.In recent years, governments and institutions have realized the importance of enterprise architecture (EA) as a viable tool and approach to improve the processes and activities of an organization [2].Several governments in various countries have initiated and adopted EA to manage a number of information systems and Figureinformation technology (IS/IT) in their environment [3].The application of technology in government management can have a positive impact on reducing costs, service time, improving quality, transparency and administrative accountability [4].
EA describes the basic infrastructure of an organization that can be utilized to arrange hardware, software and networks to meet organizational goals.Based on literature studies conducted on various existing frameworks, EA can align the objectives, purpose, and targets of the organization with the essential technical or IT framework that is required to facilitate business operations [1], [5], [6], [7].Increasing the perception of all personnel in the organization that implementing EA is necessary to achieve better implementation of EA [8].
The Government of Namibia in Africa uses EA to overcome gaps such as lack of uniformity, integration challenges that hinder processes and activities in providing socio-economic services to the community in the hope of increasing the growth of socio-economic services in the country by utilizing the framework [9].However, most government organizations prefer to design EA in their own way without using frameworks such as TOGAF, Zachman Framework and FEA so that the results obtained are not studied extensively and in depth [10].
One of the biggest challenges in IS implementation is determining and understanding the factors that influence differences from frameworks [11].Although basically various frameworks in the application of IS have the same goal, they have different concepts.Differences in frameworks can be seen based on the number of artifacts per model used and the impact of the complexity of their implementation [2] [12].Therefore, some frameworks cannot be applied in government [13].Most frameworks focus on the private sector which is fundamentally different from the needs of government [14].In addition, the challenges in technology development in government are the development of new technology and communications, the amount of data that increases continuously and the data formats are different [15].
IS is designed and built with various supporting IT platforms and tools.In general, systems are built separately from one another cause low levels of availability, consistency and effectiveness of data provision [5].One of the most appropriate IT implementations to overcome this is to implement integrated IS.The planning for the development of integrated information systems can be accomplished by utilizing enterprise architecture frameworks such as Zachman, FEAF, and TOGAF.
Korlantas is one of the Polri sub work units in the traffic sector with the main tasks and functions of formulating strategic policies, formulating traffic systems and methods, building partnerships and cooperation both domestically and abroad, and organizing coordination with other stakeholders in the traffic sector [16].In supporting the activities that are the main tasks and functions of Korlantas, an integrated system is needed that can help facilitate personnel in carrying out their duties and the community in obtaining services [17].In the service and management of IT, Korlantas is assisted by a sub-work unit, namely the Department of IT (Bag TIK) Korlantas Polri. Figure 1 is the organizational structure of Korlantas Polri.The policy for the governance of government data to produce precise, current, integrated, and responsible data, which can be accessed easily and shared between central and regional agencies, is laid out in Presidential Regulation (Perpres) Number 39 of 2019, which is called Satu Data Indonesia.This policy also involves adhering to data standards, metadata, data interoperability, and utilizing reference codes and master data [18].The policy for the governance of government data to produce precise, current, integrated, and responsible data, which can be accessed easily and shared between central and regional agencies, is laid out in Presidential Regulation (Perpres) Number 39 of 2019, which is called Satu Data Indonesia.This policy also involves adhering to data standards, metadata, data interoperability, and utilizing reference codes and master data [19].Korlantas Polri is one of the state governments in Indonesia which also play an active role in realizing and running the Satu Data Indonesia program.

Research Methods
The diagram of the research method can be seen in Figure 2.This research begins with a study of related literature and followed by data collection for analysis of current conditions.Then next stage is initiate the research step planning for EA planning.The final stage is to analyze and provide recommendations for an integrated IS implementation strategy in Korlantas.Similar research related to organizational architecture system integration planning can be found in several previous studies.Anthony pointed out that the government is required to be able to carry out digital transformation such as integrating different systems, integrating EA from various systems to support flexibility and improve services to the community [20].
The Agriculture Office of Jombang Regency in Indonesia integrates existing applications to assist the process of implementing information systems in building good e-government with a Service Oriented Architecture approach [21].In implementing EA, a framework is needed in order to have clear guidelines by comparing 4 popular frameworks such as the Zachman Framework, TOGAF, FEAF and Gartner [22].According to Rebecca, the Zachman Framework can be used as a basic framework in software systems engineering research in the government sector [23], Then there is research that helps make IS/IT planning more mature and better using the Zachman Framework adapted to EAP [24].
EA consists of infrastructure and strategies such as business processes, technical and information architecture.To support the use of Zachman's framework, an EAP method is needed in planning activities such as understanding the current conditions and designing future organizational visions, by describing the supporting architectures data, information and business process.In addition, EAP is also related to aligning IT implementation strategies with business so that planning can be implemented properly and correctly [25].
The EAP method is a method used in the development of Enterprise Architecture and can be used to plan data quality [26].EAP has been used to support business policies in achieving the vision and mission of local government to create alignment between the needs of government administration, business and technology used [27].EAP can be used to compile IT and business process requirements in the education sector [28].
From these problems, it can be inferred that there is a need for an integrated system implementation strategy to support the achievement of the goals of Korlantas Polri.This is aimed at effectiveness in designing an integrated EA that can be used by the leadership of Korlantas Polri in managing and providing services to the community digitally.

Data Collection
Qualitative methods were used to collect data which involved gathering two types of data: primary and secondary.Primary data was collected through direct observation while secondary data was collected through reviewing related research literature and internal documents.The data was then validated by interviewing 6 Korlantas personnel and their conformity with internal documents.Table 1 shows the criteria used in determining the interviewees for the validation process.

Planning Initiation
In order to commence the primary EAP tasks, a preliminary phase is undertaken which involves recognizing the regulations that are enforced by Korlantas Polri.These regulations are essential in determining the extent of the analysis and planning process, whether it will encompass the entire organization or specific parts.Following this, the subsequent step involves scrutinizing the vision and mission of Korlantas Polri.

Current Conditions and Business Models
The objective of this stage is to gain an understanding of Korlantas' architecture, technology and business functions.This entails analyzing the business models to recognize the organizational structures, business functions using value chains, and breaking down business functions and linking them to specific organizational units.It is crucial to note that the implementation of IS/IT can lead to changes in business processes [24].After that, system and technology observations were applied.

Design Architecture
The purpose of this stage is to recognize and develop architectures for data, applications and technology.[29].The data architecture stage defines entities related to business functions by listing data entities.The application architecture is used to list the potential of IS and its definition, create a relationship matrix of candidate IS with business functions and organizational units, use case diagrams, sequence diagrams, and analyze the impact of the planned IS.Technology architecture, namely defining the technology platform needed to support IS implementation and manage predetermined data.

Implementation Plan
This stage determines the strategies that can be carried out to apply each design and analysis that has been performed.At this stage, we can determine the priority scale of the IS to be integrated.

Data Analysis
The data obtained was compiled using the Zachman Framework approach by utilizing 6 perspectives which can be seen in Table 2, Table 3, Table 4, Table 5, Table 6 and Table 7.The interface used for each system is a website and mobile (android).5 When The system design schedule is carried out at the beginning of the year and system development is carried out until the end of the year (in the same year).6 Why The system built must comply with the minimum standards of application at Korlantas, all code and system documentation are provided in full, the researcher conducts a penetration test or assessment before the system is launched.

Business Model Analysis
The Value Chain approach is used to outline the Business Model, which segregates each Korlantas business function into two types: primary and supportive activities.Primary activities are those business functions that constitute the principal objective of Korlantas, whereas supportive activities are carried out to facilitate the implementation of primary activities.The results of the value chain model can be seen in Figure 3.This Value Chain has a change from before, where the application of IS/IT was not significant enough, whereas currently every main activity process uses IS/IT which makes ICT one of the main activities in Korlantas Polri.
Researchers use the results of the value chain analysis to break down business functions into specific business activities and resource cycle models.This breakdown is then correlated with relevant organizational units using a matrix to determine the responsible and accountable unit for each business function.The aim is to create a knowledge base that can be utilized to establish architectural plans.
The next step is to identify data and applications in Korlantas Polri to provide an overview of business entities and data in Korlantas.Identification results can be seen in Figure 4.
The next step is application identification to determine the application candidates needed by Korlantas.The results of the analysis are shown in Table 8.Organizational units and application candidates are linked in a matrix format to evaluate application support for each unit.The matrix results indicate that every organizational unit has a specific role in implementing applications as per their duties and authorities.Similarly, application candidates are linked to business activities through another matrix to identify the scope of each potential application for business activities.The outcome of this analysis reveals that nearly all business activities are addressed by all application candidates, and as a result, eight application candidates are recommended for implementation.
The ultimate stage involves evaluating the effect of creating application recommendations on the current applications, particularly the legacy evolution system.The impact of each prospective application will be assessed based on four categories, which include: maintaining the system without any changes and continuing with routine maintenance (R), eliminating the system entirely (SR), revamping the system to enhance maintainability (RE), and replacing the entire system with a new one (RA) [30].The results of the impact analysis carried out can be seen in Table 9.
Rachmi Azanisa Putri, Panca Hadi Putra, Ryan Randy Suryono Jurnal RESTI (Rekayasa Sistem dan Teknologi Informasi) Vol.The technology principles are established after taking into account various factors such as advancements in information technology, business models, data architectures, existing systems and technologies, as well as the requirements and discoveries of business actors within the organization.The technology architecture can be seen in Figure 5.

Implementation Strategy
The first step is to determine priorities for integration of existing applications.During this stage, the priority of application integration recommendations will be established by taking into account various conditions outlined in Table 11 as selection criteria.The objective is to ascertain the priority for the creation of SI recommendations.The selected criteria to attain this objective are urgency, working time, cost, technology (ease of use), and autonomy.
The subsequent phase involves gathering data via interviews with informants to determine the priority ratios between criteria and applications based on each criterion.The researcher will then identify priority values from the priority ratio data using the eigenvalues concept.Next is the integrated system implementation strategy in Korlantas.The strategies offered are presented in Figure 6.
The results of the research show the need for a data warehouse for database integration, but in other hand each data has its own standard, therefore the need for an AI Based Integrated Database System to obtain good and structured data.Then, complete data is needed so that Geospatial Information System technology is needed to support this operational implementation.After that, Business Intelligence and Decision Support System (DSS) are also needed to improve NTMC's performance.With so many dan vary data owned by Korlantas Polri, it needs proper visualization so that data can be easily analyzed and so on.Therefore, Smart Visualization is the right strategy for this.
Then in addition to supporting system operations, it is also necessary to provide standardized servers and periodic maintenance to meet the target of an integrated system that can accommodate all existing data from each system, standardization of operating systems and software on devices that are interconnected in the integrated system that will be developed.as well as maintenance of hardware, networks and other supporting devices at Korlantas Polri.Jurnal RESTI (Rekayasa Sistem dan Teknologi Informasi) Vol.

Conclusion
The results of the study show that to support the performance improvement of existing systems, an integrated system is required.The next step is to get five new systems that can support the integration process of each system for each Korlantas sub work unit.
Continuing with the previous recommendations, Korlantas Polri can carry out standard hardware upgrades to support IS and provide socialization of the new system to personnel so that they can operate better.
Although in this research is already proving that there is an improvement while system is integrated, there is a room for further research to carried out by analyzing more information systems and applications that exist in Korlantas Polri and their correlation with other information systems that are broader within the scope of Korlantas Polri.In addition, it can also conduct studies with comparisons or a combination of other framework approaches and other methods of conducting data analysis.
