Design Of Android Base School Information Media Application Case Study Of Qomariah Educational Institution

- Currently the world of technology and information is developing very quickly, including school information systems. The school information system is one of the information media that can be accessed by all elements of the school including teachers and students so that they can relate to each other in terms of teaching and learning activities and information that can be quickly disseminated to all students, so that students do not need to come to school. in this technological era from young to old all use smartphones to facilitate communication but PKBM Qomariah does not yet have the right information media. So an Android-based school information system application was made using Android studio. Android applications make it easier for teachers and students because they can be accessed on various smartphones. All teachers and students mostly have smartphones. With this application, teachers and students can get information from schools easily. The research method used is descriptive method by conducting observations, literature studies, and interviews. While the method used in making software is waterfall which consists of several stages, namely requirements definition, system and software design, implementation and unit testing, system integration and testing, Operation and Maintenance.


INTRODUCTION
The development of information technology is currently developing in all fields, especially in the field of education. Many difficulties or problems can be facilitated or overcome by the role of information technology. Such as data storage, word processing, data processing, finance, information management, and so on. One of the developing technologies is Mobile Application. [7] Mobile Application is software that runs on mobile devices used for mobile services. [3] Where currently many people are users of an android application. [8] As the world of information and communication technology develops, android is increasingly recognized by many people, including in the world of education. [13] An educational institution will need information that is not only timely, but also correct and accurate information. [10] The need for information media dissemination facilities that are fast and easy is increasing, especially in android applications. [8] The Community Learning Activity Center (PKBM) is a place to complete non-formal schooling that does not pass formal education. This non-formal education is intended for students from disadvantaged communities, not in school, dropping out of school and dropping out of further education, as well as productive age who want to improve their knowledge and life skills. [6] PKBM qomariah is one of the community learning activity centers in bandung district. So far, the school has had a website but it is still less than optimal. [5] The lack of information is a contributing factor to the small number of learners.
Based on the above background, the author makes android-based school information media. Android is an operating system developed by Google and designed specifically for touchscreen devices such as smartphones and tablet computers. Android is open source which means it allows anyone to change the code and distribute the software under a license from Google. [1] Android is developed using the Java language with a Software Development Kit (SDK) that provides an effective and efficient Application Programming Interface (API). [2] Application Programming Interface (API) is an interface built by system developers so that some or all of the system's functions can be accessed programmatically. [11] APIs are also commonly thought of as a collection of clear techniques for creating communication between different software components. [11] System design using the Unified Modelling Languange (UML) is an industry standard language for specifying, visualizing, constructing, and documenting the artifacts of object-based software systems. [12] The test used is BlackBox testing is a software testing technique that focuses on the functional specifications of the software. [15] The blackbox testing method is one method that is easy to use because it only requires the lower limit and upper limit of the expected data. [9] The development stage used is waterfall. The waterfall model is the most frequently used software development model. [14] This development model is linear from the initial stage of system development, namely the planning stage to the final stage of system development, namely the maintenance stage. The next stage will not be implemented before the previous stage is completed and cannot return or repeat to the previous stage. [14] In this study, the authors started the data requirement stage through observation, design, implementation, integration, and operation. [4] The result of the research is an android-based school information media application.

II. RESEARCH METHODOLOGY
This study is about the application of school information media using the experiment method. This study has the aim of improving information media at PKBM Qomariah. The steps of this research are: Requirements Definition At this stage, researchers communicate with PKBM Qomariah which aims to understand the limitations and expectations of the application to be made, information obtained using interviews, discussions and direct surveys. information is analyzed to obtain the required data.

B.
System And Software Design At this stage of application design, researchers design systems using the Unified Modeling Languange (UML) in the form of use case diagrams .

C.
Implementation And Unit Testing At this stage, researchers implement the source code and design of the Android programming language in designing the School Information Media application.

D.
Intergration And System Testing At this stage the researcher makes the application and coding, this application is tested which aims to find out whether the application from this system design is ready for use.

E. Operation And Maintenance
After this application is used and implemented, researchers perform regular maintenance in managing the application so that the application will continue to run according to its function.

III. RESULTS AND DISCUSSION
The result of this study include : A. Requirements Definition The current system is that students or visitors who want to get information must come to the school and communicate with PKBM Qomariah.

B. System And Software Design
In designing this application using use case diagrams and class diagrams.
Use case Application Diagram Figure 2. Use case diagram visitor In this use case of actors using this application. visitors only need to select the selected target image and the android will display related information. Figure 3. Use case diagram teacher In the use case of actors using this application. teachers need to use an account to enter the application, after that they only need to select the selected target image and the android will display related information. In the use case of actors using this application. students need to use an account to enter the application, after that they only need to select the selected target image and the android will display related information.

C. Implementation And Unit Testing
This stage is the implementation of the system which is the result of the design in the form of an application.

Upload gallery A page to upload photos to the gallery available on the gallery submenu page on the teacher menu. 14. Add, update, delete Announcement Figure 19. Add, update, delete Announcement A pages to add, update, delete existing announcements. 15

D. Intergration And System Testing
At this stage the researcher conducts a trial which aims to determine whether the application of this system design is ready for use, among others, by distributing questionnaires to teacher and student respondents. Delete testimony Delete testimony Fine So it can be concluded based on the results respondents through the assessment of this application is very good.

E. Operation And Maintenance
At this stage, researchers perform regular maintenance in managing the application so that the application continues to run according to its function and can be developed further. based on the table above This application is still in the development stage including correcting errors that were not found in the previous step and is expected to help, facilitate and improve school information services.

IV. CONCLUSION
based on the results of research conducted regarding Design Of Android Base School Information Media Application Case Study Of Qomariah Educational Institution it can be concluded that backbox testing shows that this application can run well.
