Abstract

The design of a sound resonance practicum tool is designed to determine the differences in the speed of sound propagation in air in small pipes and large pipes. The tool is designed based on the concept of sound resonance which is carried out on large and small pipes immersed in water to find harmonic frequencies with the help of a frequency generator application of 1250, 1500 and 1750 Hz. The practical design of the tool and the simple experimental procedure make it easy to use. Experimental results on small pipes with a frequency of 1250, 1500 and 1750 Hz obtained the length of the air column (L) of 13.603, 11.33 and 9.73 m with the speed of sound in air (v) of 340, 340 and 340, 5m/s. In large pipes with a frequency of 1250, 1500 and 1750 Hz, the length of the air column (L) is 13.6, 11.34 and 9.73 m with the speed of sound in air (v) of 340, 340 and 340, 5m/s. Based on the experimental results, there is no difference in results and the relationship between the magnitude of the frequency and the length of the air column is the same, that is, it is inversely proportional, while the value of the speed of sound in air tends to be constant at a value of 340 m/s – 340.5 m/s.

Abstract

Learning media is an important component that must exist in every learning process takes place. The use of instructional media greatly influences student interest and learning outcomes, besides that the use of instructional media also influences student learning motivation. This research method uses a quantitative approach with an appropriate research design. The research sample consisted of class XI high school students. Data collection was carried out using a questionnaire as a research instrument, specifically designed to measure the level of student interest in the material and student perceptions regarding the use of virtual laboratory-based learning media and interactive worksheets. By going through the validation and reliability tests, the result is that the student learning interest questionnaire is valid. The results of the study concluded that appropriate, interactive and interesting learning media can increase students' interest in learning, especially in exact subjects such as Physics. By increasing student learning interest, student learning outcomes will also increase, as well as the level of student completeness will also increase
