A web application interface using the web service technology is required for enabling the interaction of various web applications on different platforms. This work describes a web application interface (called SIMPEL), developed to integrate the MOODLE (Modular Object-Oriented Dynamic Learning Environment) with an academic information system. The SIMPEL benefit goes beyond the mere creating synchronization between academic data and teaching/learning resource. It improves several functionalities which are lacking in the MOODLE such as the capability to use the most of input from the academic information system, presenting the sequence of activities and providing the facility to design different activities to different group of students. In this work, Model Driven Architecture (MDA) and Service Oriented Architecture (SOA) are combined as an approach to develop the SIMPEL. The implemented SIMPEL is analyzed in the teaching/learning activities at Department of Electrical Engineering University of Lampung (Unila) during the trial period and the result showed that SIMPEL can properly perform its functionalities to guide students and teachers in their activities.
