Abstract

This study aims to develop a diagnostic test for understanding the concept of sound waves and to test the validity and reliability of the test. The research method used is development research with reference to the ADDIE model (Analyzing, Designing, Developing, Implementing, Evaluating). This research was conducted at a senior high school in the city of Bandung involving 30 students as respondents. The stages of developing a diagnostic test include literature study, needs analysis, formulating competencies and indicators, developing test items, expert validation, test trials, reliability analysis, ease of analysis, discriminating power analysis, and item selection. The validity of the diagnostic test for understanding the concept of sound waves was tested using several techniques, such as content validation and construct validation. While the reliability of the diagnostic test was tested using the K-R.20 calculation. The results showed that the developed diagnostic test for understanding the concept of sound waves had good validity and reliability. This test can be used to measure students' understanding of the concept of sound waves and to identify difficulties experienced by students in understanding the concept.

Abstract

The research purpose was to develop and determine feasibility of interactive multimedia instructional game model. The research method used R&D with 4D stages. The reseach was conducted grade V in SD NEGERI 3 Batudaa Kabupaten Gorontalo Provinsi Gorontalo. The result was average score of 91% from media design experts was very feasible criteria, the material experts obtained an average of 85% was very feasible criteria and the practitioner experts obtained an average of 98% was very feasible criteria. Based on this, the interactive multimedia instructional games model was suitable for use for grade V in water cycle concept.

Abstract

This study aims to visualize the temperature distribution on metal plates by solving elliptic differential equations using the help of the Microsoft Excel program. Many physics problems have limited analytic solutions so a numerical solution is needed. One of them is about the temperature distribution on a homogeneous metal plate in a steady-state conditionThe equation of heat flow in steady-state conditions is an elliptic partial differential equation (PDE). By solving this equation, we will have a numerical model of the plate that can be a mesh with a certain temperature point. Each point has been known to calculate the temperature value. The temperature value influenced. The Temperature value influenced borders on the plate and the presence of heat generation. The edge of the plate can be a constant temperature, a convection zone with the outside air, or an isolated edge. This model is then processed using Microsoft Excel with the iteration calculation until the temperature distribution value is obtained. The results obtained a graphical visualization of temperature distribution on the plate.
