Geofoam is a geosintetik material made of Expanded Polystyrene (EPS) and Xtruded Polystyrene (XPS), which has a low weight property which makes geofoam widely used as a lightweight fill material and has been applied in Europe, especially in Eastern Europe. This is a preliminary research that emphasizes on the use of geofoam as a fill material on soft ground through theoretical analysis using Plaxis program. Supporting data used covers data of basic and fill ground taken from specific locations which are planned for subsequent research as a field test. Based on the Plaxis program results, the use of geofoam as a fill material give a higher safety factor value with a smaller deformation compared to laterite soil. This result indicates that the use of geofoam as a fill material can be considered to be applied in the country.

Multimedia can be used as a supportive element in education. The most significant implementation of multimedia is shown in computer assisted instruction (CAI). It is a self-instructional program which provides an accessible, interactive, and flexible way of presenting curriculum material. Therefore, this research objective is to design and develop a CAI for physics as a supportive learning method at school. Interactive Multimedia System Design & Development Cycle is used as the research method. It explains about a development and design cycle, especially for interactive multimedia system. Any information and data for analyzing user's need are obtained through questionnaire and interview. From the research, it is shown that most of the students face difficulties in learning physics as they imagine the logic or process that happens. Being implemented, most students as well as teachers are interested in this application that makes it easier for them to understand the physics process.
