Aspergillus sp. GPN IMMOBILIZED ON USED FABRIC MATRICES AS A BASE MATERIAL IN A WASTEWATER TREATMENT PLANT FOR THE DECOLORIZATION OF BATIK WASTEWATER

Abstract

The Ministry of Industry stated that there are indications that the textile industry in the watershed area (DAS) discharges its waste directly without going through a wastewater treatment plant (WWTP). Textile wastewater including batik and industrial waste with wastewater containing dyes is a problem that gets a lot of attention, especially in the environment of textile industry centers such as batik because it is a source of water pollution. The dye waste pollution can be overcome by applying a combination of physical, chemical and biological waste treatment methods. Biological methods with bioremediation such as the use of fungi have promising prospects because they are sustainable, environmentally friendly and economical, so it is necessary to develop their application systems on an industrial scale. The results of previous research found that Apergillus sp. strain GPN succeeded well in degrading batik waste, but there has been no research in the form of preparations that can be used for applications in WWTP. On the other hand, a lot of fabric material is wasted after the covid pandemic, so it can be reused as a practical poduct as a mycelium immobilization matrix. The purpose of this study was to determine the ability of Aspergillus immobilized on used fabric material and its ability to decolorize batik waste. The results of this study showed that Aspergillus mycelium can be well immobilized on used fabric materials so that it can be a product of sedimentation. The results of this study showed that Aspergillus mycelium can be well immobilized on used fabric materials so that it can be a practical product for filter raw materials in WWTP. The immobilized product can decolorize >80% of batik waste, with and without sterilization treatment.
