Abstract

The purpose of this study is to find out the ethnoscience study of making Ikat Karaja woven fabric in Sodana Village, Lamboya District as a Science Learning Source. This research uses a qualitative method. The data was obtained from the results of observations, documentation interviews and analysis. The instruments used in this research are: observation sheets, interview sheets and documentation. Data analysis techniques through the stages of data reduction, data presentation and conclusion drawing. The results of the study show that: The amount of biodiversity on the island of Sumba is reflected in the traditional equipment and materials used in the smelting process, which are divided into various categories.
