ABSTRACT Balagtas, Jaswin M, Malonzo, Romeo Russel R. Tamondong, Ruzze Department af Computer Studies and Automation -College of Engineering and Computer Studies June 2020 DEVELPOMENT AND MPLEMENTATION OF WEB APPLICATION BIODIVERSITY SYSTEM Adviser. Ms. JACKILYN B. BACCAY The study entitled "Development and Implementation of Web Application Biodiversity Infomation System" aimed to design and develop a system that manages all the profling of fiora and fauna species in Mount Arayat The study can be helpful to PSAU-CAS Department of Natural Sciences staff for it would be easy for them tomanage, track, and report infomation through a web application system thereby replacing the manual system The researchers used different techniques such as interview, Iintemet search and Survey Questionnaires to gather all the information needed in the completion of the study. The researchers adapted the System Development Life Cycle methodology as it allows a fast development through the accelerated time cycie. For the design and development of the system, the researchers used different software such as Laravel as framework of PHP, HTML Javascript and CSS. To determine the design and flow of the system, diferent diagrams were also used such as Context Diagram, Use Case Diagram, Data Flow Diagram, and System Flowchart Through testing the approval of capabilities and funcions of the system to the users, the researchers collected a good result in the survey conducted and the study gathered a grand mean of 3.79 which imples that the respondents strongly agreed that the developed system has successfuly meet the set objectives.
