Handayani W., Widianarko B., Pratiwi A.R., 2020, Water Footprint of the Natural Coloured Batik-Making Process: A Study on a Batik Small Enterprise in Jarum Village, Klaten Regency, Indonesia, Chemical Engineering Transactions, 78, 223-228.
Indonesian batik is usually produced by Small and Medium Enterprises (SMEs) which tend to induce environmental problems. Batik wastewater has caused pollution in some regions of Central Java, resulting in odour, allergic reactions among the local population, and the degradation of water quality. Batik production also requires a substantial volume of water. This study examines the water footprint of natural coloured hand drawn batik-making process by a small enterprise in the Jarum village, Klaten. Blue Water Footprint was determined by direct measurement, while Grey Water Footprint was estimated by calculating the water required to dilute COD. High concentration of TSS, BOD5, and COD were found in natural dye extracts and wastewater. The Water Footprint (WF) analysis indicated that Grey Water Footprint was 37,343.15 L/d, which has a higher portion in the total WF than the Blue Water Footprint which was only 105.63 L/d. This result indicated the need to reduce pollution and to increase awareness among batik artisans. Promotions of behavioural change toward a more efficient use of water resources are advisable.
