I. INTRODUCTION
Geographic information systems (GIS) have been adopted as a useful tool by a wide range of disciplines such as environmental planning, property management, infrastructure siting, emergence planning, automobile navigation systems, urban studies, market analyses, and business demographics. Analyses from GIS can determine both threats and opportunities for development [1]. With the rapid growth of computer technology, researcher and engineer developed Geographical Information System (GIS) to gather and use spatial information.
A GIS can be used to capture, prepare, manage, manipulate, analysis and present geo-referenced data [2]. With GIS people can gather spatial data efficiently, quickly, and accurately. Over the past decade, researchers have done many researches about GIS and its application. A GIS can be used to help people in transportation [3,4], real estate [5,6], green energy [7,8], crime mapping [9,10], and many more areas.
Technical Implementation Unit for Instrumentation Development (UPT BPI) is one Echelon III unit in Indonesian Institute of Sciences (LIPI) whose job is to carry out services in the field of calibration and instrumentation research and development [11]. UPT BPI also responsible with public services such as calibration services and training. From those public services UPT BPI has many customers scattered all around Indonesia.
With the many of customer in number, it is actually possible for UPT BPI to utilize the data and analyze it in order to optimize services.
From the customer data and their transaction history, it's possible to analyze the national needs of calibration and instrumentation. When the customer instrument’s calibration expiration date is close, it possible to make a reminder for
Software Development Life Cycle (SDLC) used in system development is waterfall [12]. The process begins with Requirements Definition, then System and Software Design, Implementation and Unit Testing, Integration and System Testing, and Operation and the last is Maintenance. Waterfall method can be seen in fig. 1.
III. DEVELOPMENT
Requirements Defined by observed and depth interview with UPT BPI's staff and management, especially the one that directly related with Customers, Calibration and Training services which are metrology and public relation section. This stage is important because it's like setting our destination before we make a journey. Information from this stage will determine where the direction of development goes, how much resources do we need, and most the important, how should we design the system.

After the requirements are defined, the next step is System and Software Design. This step is crucial as this step will determine how the system will be built. If the design is bad, chance are there'll be many changes in the system while the software is developed, and there'll be also a lot of bugs come from the software. When it happens, we'll be forced to go back to the previous stage and redesign the system. This is clearly inefficient because we will be wasting our resource to build a system only to tear it down again because it's not usable.
The modeling tools used for System and Software Design in this study is Unified Modeling Language (UML). It's one of the most common modeling tools and could model not only application structure, behavior, and architecture, but also business models and data structures [13].
A. Use Case Diagram
There are two actors in this system. Admin can access all the features on the system, including Manage User, Manage Customer Data, Manage Services, and Access Services Information. Those features require admin to login into the system. In each manage feature, admin can add, edit, delete, and search data. While admin can access all the features on the system, the second actor, and public can only access map. User can filter which data to display. For details see fig. 2.
B. Activity Diagram
1) Access and Filter Map
To access map, user just required to open the app, then map will be displayed in the home page. In the map, user can filter which data to display on the map. The filter is based on category of the customers. The category is Instrumentasi, Kalibrasi, Kerjasama, Pelatihan and Produk Hasil Penelitian.
Figure 2 Use Case Diagram
To filter the map, user needs to select which data to be displayed or filtered by checking or un-checking the category checkbox. After user click the filter button, system will filter the data displayed on map based on user selection. For details on those activities, see fig. 3 and fig. 4 below.
2) See Customer Details
User can see customer data which contains customer name and address by clicking customer marker on map. To see their transaction history, user needs to click customer name and
system will show the customer’s transaction history. See fig. 5 for details.

Figure 5 See Customer Details
3) Login
Before admin can access admin dashboard, admin needs to login into the system. In the login page, user input their username and password, the system will check user login credential. If login not valid, error message will be displayed, telling user his/her login credential is not valid. If login valid, system will take user to admin dashboard. Login activity can be seen on fig. 6.
Figure 6 Activity Diagram - Login
4) Manage User, Customer and Services
The activity for these three use cases is basically same. User open one of the menu and system will display the menu page. In manage user menu, system will display the list of users and some of their basic data. The data displayed in paginated row, and each data has action button, allowed admin to edit and delete the data. There's also a search box for admin to quickly search specific data. Manage user, manage customer, and manage service activity can be seen on fig. 7, fig. 8, and fig. 9. Search, add edit, and delete data activity will be explained in next section.

Figure 8 Activity Diagram - Manage Customer
5) Search
Admin can quickly search specific data by inputting search keyword into the search box. The system will check for data in the database. If system found the data, search result will be displayed, and if not error message will be displayed. Search activity can be seen on fig. 10.
6) Add Data
To add data, admin needs to fill all required data field in the page, then click add button. System will insert the query into the database. If the insertion is successful, success message will be displayed, telling user that data has been successfully added into the database. If the insertion is unsuccessful, error message will be displayed instead. See fig. 11 for details.
7) Edit Data
After editing desired field in the edit page, admin needs to click edit button to confirm editing. System will call the update query into the database. If the editing is successful, system will take user back home menu. If the editing is unsuccessful, error message will be displayed. See fig. 12 for details.

C. Entity Relationship Diagram
Entity Relationship Diagram shows graphical representation of table entity in the database and their relationship. There are four entities in this application: category, service, customer, and user account. See fig. 14 for details.
IV. IMPLEMENTATION
The designed system then coded and implemented into the actual application. The application developed using PHP as programming language and MySQL as Database Management System. CodeIgniter used as the framework for the application and Google Map API used as map engine.

B. Blackbox Testing
Blackbox testing used to figure whether the system works as intended or not. Blackbox testing on this application can be seen on table 1.
C. Maintenance
Operation and maintenance will be conducted by IT staff at public relation section. The staff is responsible for managing the application, log any bugs or error and report it once a month. The report will be handed to development team to be analyzed, fixed, and further developed.
V. CONCLUSIONS
This development of GIS customer distribution mapping helps staff and management of UPT BPI to understand their customer and plan better for their marketing strategy. But the developed system is still at an early stage, which only covers data collection and visualization on the map. Further development needed to be done to make this system more useful. One of our suggestions is to add an analytical and forecasting feature to the system.
