Organic Material for Clean Production in the Batik Industry: A Case Study of Natural Batik Semarang, Indonesia

Abstract

Batik has become more desirable in the current fashion mode within the global market, but the environmental damage induced by this fabric’s synthetic dye practices is a matter of concern. This study aimed to discuss the application of organic materials as natural dyes in the clean production of textiles to maintain the environment. The research was a case study from the community services program in Kampung Malon, Gunungpati, Semarang City, Indonesia, focused on the batik home industry of the Zie Batik fabric. Furthermore, natural pigments from various plant organs (stem, leaves, wood, bark, and fruit) of diverse species, including Caesalpinia sappan, Ceriops candolleana, Maclura cochinchinensis, Indigofera tinctorial, I. arrecta, Rhizopora spp., Strobilantes cusia, and Terminalia bellirica were used for this type of material. These pigments are more biodegradable, relatively safe, and easily obtained with zero liquid waste compared to the synthetic variants. The leftover wastewater from the coloring stages was further utilized for other processes. Subsequently, the remaining organic waste from the whole procedure was employed as compost and/or timber for batik production, although a large amount of the wastewater containing sodium carbonate (Na2CO3), alum (KAl(SO4)2·12H2O), and fixatives (Ca(OH)2 and FeSO4) were discharged into the environment during the process of mordanting and fixating, with the requirement of additional treatment.
