Since this research has gone well, Labuhan Regency people can know the information and help them find health centers faster after this webgis is installed. Study of the life cycle of system development using SDLC (Systems Development Life Cycle) using UML to design spatial information systems to help solve problems. This will help the public to locate the nearest health center. Keywords: Information Systems, Webgis, Community Health Center, Waterfall Method, Black Box Testing Copyright © 2021 Jurnal Mantik.

Labuhan Batu Regency has a strategic position on Sumatra's eastern route, at the junction between the provinces of West Sumatra and Riau, connecting Sumatra and Java growth centers. Has ample access to foreign countries due to proximity to Malacca Strait. One square kilometer is 2.561.38 km2. 498,178 people learned how to build a geographical information system (GIS). Can provide specifics of the location and distribution of healthcare facilities in Labuhan Batu Regency as puskesmas [1]. Labuhan Batu District has about 15 health centers, including 9 non-inpatient health centers and 6 inpatient health centers. Puskesmas distribution in Labuhan Batu Regency is not determined by population density, particularly in areas where the population continues to rise year after year.[2]. A GIS is an information system used to handle spatial data or geographic coordinates. In other words, sig is a database device uniquely capable of simultaneously managing spatial data or building data using a sequence of work operations.[3]. The project aims to create a mapping application as a puskesmas management tool that uses a geographic information system for better location identification.. [4]. SDLC digunakan untuk membangun sistem informasi geografis untuk puskesmas dalam proses ini, sedangkan UML digunakan untuk mendefinisikan desain sistem.[5]. This study aims to establish the Geographical Information System (GIS), which can provide community information about health services via the Labuhan Batu Regency Puskesmas. The benefits of this research were realized, with Labuhan Batu Regency now having better access to district puskesmas information and place. 2. Method This is a significant step in developing a Sommerville-based waterfall system. [6][7]. a. Requirements definition This method gathers all applicable data in its entirety and analyzes it for potential software requirements. This stage is complete, producing ready-made design. b. System and design software After collecting and processing the data, the next step is to turn it into a software design type. c. Implementation and Unit Testing At this stage, design is converted into software, and no programmatic or logical erroneous operation exists. d. Integration and System Testing The developed program will be tested as a full system to decide whether it is software-compatible and worth delivering to the costumer.
