Abstract

Solid-state is a compulsory subject in the Physics Education study program. Therefore, the level of complexity—depth—of the material taught is moderate. However, students are facing some obstacles in understanding crystal structure material that is related to microscopic structures. This research aims to apply diamond software media to crystal structure material, from which students' scientific attitudes can be discovered. The method used in this study is the qualitative description. The research subjects totaled 23 students. The data collection technique was carried out by measuring students' scientific attitudes after using the Diamond software. The results showed that the Diamond software could be used in Solid State Physics course. In contrast, the scientific perspective showed good results, which is indicated by the scientific attitude questionnaire score reaching more than 80% within the high category. Meanwhile, student responses indicate that the acceptance rate of Diamond software as a learning medium in Solid State Physics course is 86.25%, or falls into the high category.

Abstract

This study seeks to investigate the shape of the surface of tsunami waves using the finite difference method and the effect of the damping function on the simulation of tsunami wave propagation using Matlab-based visualisation. The effect of attenuation on the propagation of tsunami waves is measured by the variation in energy. The results of the investigation indicate that tsunami waves have a transverse wave form, with waves propagating in a perpendicular direction. In the meantime, the analysis of the damping function reveals a decrease in the value of energy; this indicates that if the damping function is provided, it will have the effect of reducing the wave energy and propagation speed of tsunami waves. This modelling clearly and realistically illustrates the results of wave movement visualisation and provides insight for disaster mitigation and coastal protection.
