| Judul Artikel | Decolorization of Naphthol Batik Effluents Using Immobilized Enzyme of Aspergillus sp. 3 and Zeolite-Activated Carbon in Different Incubation Time |
| Abstrak (Bhs. Indonesia) | Batik is an Indonesian traditional textile in which beautiful patterns are created on a textile surfaces using wax and dyes. Naphthol is one of common dyes used for textile and batik dyeing process. Naphthol (acid dyes) is recalcitrant and is one of azo dye types characterized by the existence of one or more azo groups bound to aromatic rings. The wastewater of the batik industry has murky color, wide range of pH, high heavy metals, and high dissolved substances therefore endanger the environment and human health. Textile wastewater treatment can be processed through chemical, physical, and biological based approach. Physical method through adsorption can be done using zeolite and activated carbon. Meanwhile the biological technique using fungi can be used to decolorize the dye effluents. In previous research, ligninolytic enzymes of Aspergillus sp. 3 are reported to play a role in degrading lignocellulosic substrates. In this study, the potential of whole broth enzyme of Aspergillus sp. 3 in degrading polyaromatic hydrocarbons and recalcitrant textile dyes is observed. To maintain the enzyme stability in whole broth, the enzyme is immobilized in chitosan beads. This research used the combination of biological method using immobilized whole broth enzyme of Aspergillus sp. 3 and physical method using zeolite-activated carbon in a wastewater treatment plant. This research was conducted using experimental design with Completely Randomized Design (CRD). The independent variables of this research are different incubation times (24, 48, and 72 hours) and naphthol dye types (naphthol red and naphthol blue black). Meanwhile, the dependent variable is the capability of immobilized enzyme of Aspergillus sp. 3 and zeolite-activated carbon to decolorize naphthol batik effluents. The main parameter measured is the percentage of decolorization and the supporting parameters involve TDS and pH values. The collected data is analyzed using ANOVA with confidence level 95% and 99%. Furthermore, the correlation between incubation time and decolorization percentage was observed with regression analysis. The result of this research shows that the treatment using the immobilized enzyme of Aspergillus sp. 3 and zeolite-activated carbon is highly significant to decolorize the naphthol batik dye effluents. The most significant result for naphthol blue black decolorization is 72 hours incubation time. Whereas, there is no significant effect of toward naphthol red decolorization along incubation time. |
