Ethnophysics on the dynamical concept of "ancak Robyong": A local Wisdom in East Java Indonesia

Abstract

This research aims to develop physics learning media that integrate local wisdom in schools or communities and analyze the ethnoscience concept of Ancak Robyong. The research method used in this research is a qualitative approach. In addition, there is a literature study of journal sources, books, writings related to the problem, observation, and interviews. The results of this study are the analysis of physics concepts in the local wisdom activities starting from the process of making Ancak Robyong there is the concept of equilibrium, the lifting process there is the concept of the Newton First Law, the process of carrying there is the concept of equilibrium of a rigid body, the shaking process there is the concept of the Newton Third Law, the arak-arak process there is the concept of effort which is the movement from one place to another and the reflection of Ancak Robyong colour to know the process of reflecting light so that residents can see the beauty of Ancak Robyong. Thus, the local wisdom of Ancak Robyong is used as a learning medium, especially in Physics, to improve science-physics knowledge (Ethnophysics) into real scientific knowledge.
