Abstract

This research aims to explore the ethnoscience of the Terbang Gembrung percussion instrument of the indigenous community in Kampung Naga, Tasikmalaya, West Java, and its potential as a local context in physics education. The Terbang Gembrung percussion instrument of Kampung Naga employs an acoustic membrane of goat leather with an air column of albasia or manglid wood. The research methodology encompasses qualitative descriptive methods, including literature study and interviews, as well as observation methods involving the measurement of sound frequency generated using the Decibel X smartphone application under conditions where the instrument produces typical sound. The Terbang Gembrung tradition holds religious value and is commonly performed during significant celebrations such as Eid al-Fitr, Eid al-Adha, and other religious festivities. Based on the observation results, it was found that four types of percussion instruments produce sound frequencies at four harmonic levels according to the membrane size. The first harmonic has a frequency of approximately 199.0 Hz, the second harmonic around 211.5 Hz, the third harmonic approximately 231.5 Hz, and the fourth harmonic around 261.0 Hz. The design of the percussion instrument is in the form of a half-spherical cone, with the cross-sectional area decreasing from the membrane to the end of the air column. The potential application of science principles to the Terbang Gembrung percussion instrument makes it a cultural artifact that can serve as a local context in physics education at the high school level, focusing on the topics of sound waves, especially sound intensity and sound frequency.

Abstract

The science teacher development program on STEM Learning using Arduino was conducted to enhance science teacher competencies in designing and implementing a 21st-century skills-based teaching approach. This study implemented research evaluation with Context, Input, Process, and Product (CIPP) to determine the drivers that supported and enhanced the program's effectiveness and address the barriers that obstruct teachers' competencies. The methodology employed in this study is both qualitative and quantitative methods. Qualitative methods gather data through observations, interviews, and document analysis. In addition, quantitative methods involve calculating the percentage of participants who complete the training program. Interviews and document studies in context evaluation help determine if program objectives are relevant to teachers' needs and aligned with the curriculum. Observation, interview, and document study were employed to evaluate input, process, and product and complement with quantitative data. The result shows that the science teacher development program is highly relevant today in enhancing teachers' competencies to design 21st-century skills-based teaching. However, some improvements are still needed to support the drivers and eliminate the barriers to make the program more effective. Some drivers, such as participants' motivation, well-organized content, competent facilitators, and sufficient resources, are assets to continue the program. However, the revision of the indicator objectives program, the selection process of participants, the time to conduct the workshop session, guidance, and content representation are essential to note.
