Abstract
One alternative method of physics learning is inquiry to create active learning centered on learners by involving media as an object of study. This study aims to explore the understanding of students about the kinds of traditional Mbojonese musical instruments and mastery of basic concepts of vibration-waves, as well as design learning activity by constructing a concept through exploration of a traditional music instrument, a Gambo. Data were collected from a group of physics teacher candidates through observation and completion of a questionnaire sheet and instrument concepts comprehension test. Data relating to responses in the learning process are expressed in percentages and analyzed using descriptive quantitative rating scales. However, the quantitative data of learning outcome were analyzed statistically with normalized gain determined by the hake factor (N-gain). Based on the result of the research, it is concluded that the basic conceptual understanding of students is still in the minimal category, but the design of inquiry activities with traditional musical instruments can increase the effectiveness of physics learning, which is indicated by active questioning, positive responses and good performance of the learners in the investigation activities, as well as an increased understanding of the basic concept of vibration-waves.
