Abstract

Experimental activities are part of physics learning process with the aim of gaining knowledge and having good understanding of physics concepts. Sound and organ pipes are the main subjects discussed in physics and engineering lessons. These materials contain facts accompanied by actualization in everyday life in social life. However, the fact in high school (SMA) physics learning is that experimental activities in supporting students’ learning and understanding have not been widely carried out. This is due to the lack of practical support tools. The purposes of this research are to design a sound experimentation tool design of an open and closed organ pipes and to determine the value of the speed of sound which propagates through air medium using a data acquisition technique assisted by sound analysis oscilloscope software. This type of research is a Research and Development research with five stages referring to the ADDIE model. The first stage was analysis, that was done by conducting a study of the problems of physics learning at senior high school level, especially in sound chapter. The second stage was design, namely designing experimentation tools. The third stage was development, that was done by providing materials that were used in the experiment. The fourth stage was implementation, that was testing the tool which had been made combined with sound analysis oscilloscope software, and the fifth was conducting an evaluation and feasibility test based on the validity of the experimental data. The data analysis technique used average and linear regression by utilizing the results of data from frequency analysis using sound analysis oscilloscope software. The results showed that the experimentation tool in this study was able to be used as learning media for the sound and open and closed organ pipes materials. The experimental results obtained that the speed of the sound waves propagation in air for an open organ pipe was v = 332.19 m/s with an accuracy rate of 97.70%. While the value of the speed of the sound waves in air for a closed organ pipe was v = 334.69 m/s with an accuracy rate of 98.44%.

Abstract

This research aims to: (1) create a design of a modest water plan for mathematics lessons with the material of fluid, (2) describe the improved psychomotor skills of the learners from the learning process with the created design, the modest water plan, for mathematics lesson with the material of fluid, and (3) describe the learners' responses toward the design of the water pump with the lesson of fluid mechanics. This Research & Development applied the ADDIE model with five stages. The first stage was analysis. The researchers reviewed the physics learning problems for Senior High School learner levels, specifically in the chapter on fluid mechanics. The second stage was the designing stage. The researchers designed the experiment tools. The third stage was the development stage. The researchers provided the materials to experiment. The fourth stage was the implementation stage. The researchers used the pre-created tool in a trial run test. Then, the fifth stage was the evaluation stage. This stage involved the reliability test based on the data validity of the experiment results. The results showed that: (1) the design of the modest water pump was applicable as the media of fluid mechanics learning, (2) the pretest-posttest results of the trial run test showed the improved aspect of the learners' scientific process skills; and (3) the learners' responses toward the design as the learning media for fluid mechanics was categorized "excellent."
