Abstract

Discrete Mathematics is one of subject which requires media to support the learning process. Besides, with development of long distance learning ( e-learning), it enables to perform some learning and also test can be on-line. Therefore, it necessary to research developing Discr ete Mathematics on-line test based on web which can assist lecturer and also student. Many steps taken at this project are requirement analysis of system, system design, implementation, and system test. Designs of system appl ies Unified Modeling Language (UML) which consists of functional modelling, structural modelling, and behavior modelling. Implementation stage is applied PHP as web programming, MySQL as database, and Apache as web server. Testing methods consist of many steps, those are: unit testing, integration test, system test and acceptance test. From results of the research, it can be concluded that the application of Discrete Mathematics on -line test can present one question in one pages, developed with 3-level examination and can be applied in picture and also text-formed questions which can present mathematical problems, and equiped by mechanism of automatic evaluation. Based on result of alpha test, the application still ha s some weaknesses on security and safety, those are: security and safety on inactive JavaScript function by user and a weakness to prevent SQL injection and spam. From the three weaknesses there are two weaknesses which have been repaired by giving mechanism of detection JavaScript at browser and PHP code to prevent SQL injection. Keywords : on-line test, mathematical problems, automatic evaluation .
