For years, LOGOS reformed evangelical education does not have a centralized and organized academic information system. the data is being kept in archives and this situation complicates the school to control the school's work and quality, such as student's grades data that are still kept in paper archives, unstructured student's data, manually written cash flow transaction and others. Based on that problems, the splution is to make a design and implementation of web-based school administration information system on LOGOS school. the system will facilitate the arrangement and data storage for the school administration information system's data, and the school's cash transaction system. this web based school administration information system is using internet as its media, and constructed using PHP v5.0.5, PHP Designer 2007 and MySQL 5.0 From the implementation and application setting, it can be concluded that the system is useful enough to be used as school administration information system. however, it also can be concludedthat there is a lack of interface design in the report forms.
