Scientific reconstruction of indigenous knowledge of batik natural dyes using ethno-STEM approach

Abstract

Abstract This research intended to analyze the community’s knowledge scientifically of batik process and types of local plants used as natural dyes for batik colouring. The study took place at one of local batik manufactories, Zie Batik, situated in Malon Gunungpati, Semarang, Indonesia. The research instrument was observation and interview sheets. The observation of the batik making process and interview with the manufactory owner unveiled the batik techniques, tools, materials, and creative ways to produce good quality batik motifs, dyes, and calculate profit and loss. The obtained data were then analyzed scientifically through the stages of verification, reduction, validation, and conceptualization based on the Ethno-STEM approach. The analysis results revealed that there are numerous plants used in making batik that could produce color substances. Moreover, the steps of the batik process were also explained. The scientific knowledge reconstruction based on the STEM aspects showed that owners and artisans possess the proper batik techniques and methods, have creative ideas on how to produce high-quality colors and batiks, and get traditional as well as modern sales management. Scientifically, the natural dyes contain secondary metabolite compounds. Scientific knowledge in chemistry about the process of fixation, extraction, solution, alum compounds, anthocyanin, and pigments were also found in the Batik process
