“…The duration of contact between the fungal mycelium and the dye affects the activity of the fungi in changing the color. However, at a certain time, the absorption rate will decrease if the fungus is at a critical point of absorption (Dewi et al 2019a). The clear color indicated that there was a degradation process that changes the chemical structure of the dye.…”

Synthetic dyes are more widely used in the batik industry; one of them is indigosol golden yellow dye. Decolorization of synthetic dye can be done by fungi. This study aimed to identify a selected fungal isolate from batik waste that was capable of decolorizing indigosol golden yellow dye based on the morphological and molecular characteristics, as well as analyze the physico-chemical characteristics of batik effluent. Based on the morphological characterization, isolate K ByT1 was similar to Trichoderma and was identified as Trichoderma yunnanense by ITS rDNA sequence (OP 420536). Isolate K ByT1 was able to optimally decolorize 96.3% indigosol golden yellow dye at a concentration of 250 ppm with an incubation time of 168 h. The growth of T. yunnanense at the incubation time of 48–100 h was in an exponential phase, in which percentage efficiency in decolorization was greatly increased. The existence of an indigosol golden yellow dye degradation process by T. yunnanense was indicated by a rough, thick mycelium and the presence of dye attached to the mycelium (SEM observation), as well as the loss of functional groups C≡C bonds, –C=N, chain N=N, aromatic nitro compound, P=O stretch, ortho aromatic, C-Cl stretch, C-S stretch, C-I stretch, and S-S stretch (FTIR analysis). T. yunnanense was able to decolorize 34.54% of batik waste with an incubation time of 240 h. The indicators of wastewater treatment efficiency – namely, biological oxygen demand (BOD), chemical oxygen demand (COD), total dissolved solids (TDS), sulfide, total suspended solids (TSS), pH, oil, and fat with removal percentages of 32.68, 23.74, 12.69, 56.63, 37.14, 18.21, and 52.78%, respectively.

“…Dekolorisasi pewarna menggunakan jamur dipengaruhi oleh jenis jamur yang digunakan dan kondisi lingkungan seperti pH, waktu inkubasi, dan temperatur (Saetang & Babel, 2010). pH berbeda menyebabkan nilai dekolorisasi yang berbeda pula (Dewi et al, 2019a). Waktu inkubasi dan pH optimum yang dibutuhkan tiap jamur pelapuk putih berbeda untuk mendekolorisasi pewarna.…”

Jamur pelapuk putih diketahui memiliki kemampuan untuk mendekolorisasi pewarna, salah satunya jamur Ganoderma sp. dari Kebun Raya Baturraden. Jamur tersebut mampu mendekolorisasi Remazol Brillliant Blue R (RBBR) yang bersifat toksik, mutagenik, karsinogenik, dan stabil terhadap perlakuan fisika maupun kimia, Proses dekolorisasi dapat dipengaruhi oleh faktor lingkungan seperti waktu inkubasi dan pH. Setiap jamur pelapuk putih memiliki waktu inkubasi dan pH optimum yang berbeda dalam mendekolorisasi pewarna. Penelitian ini bertujuan untuk mengetahui kemampuan isolat Ganoderma sp. dari Kebun Raya Baturraden dengan waktu inkubasi dan pH berbeda dalam mendekolorisasi pewarna RBBR, serta mengetahui variasi waktu inkubasi dan pH yang menunjukkan hasil terbaik. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) dengan Perlakuan variasi pada penelitian ini terdiri dari waktu inkubasi yaitu 24, 48, 72, 96, dan 120 jam, serta pH 3, 4, 5, 6, dan 7. Analisis data menggunakan metode Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Beda Nyata Jujur (BNJ). Hasil penelitian menunjukkan bahwa Ganoderma sp. dari Kebun Raya Baturraden mampu mendekolorisasi RBBR pada waktu inkubasi dan pH berbeda dengan persentase dekolorisasi 4,10% - 83,04%. Persentase dekolorisasi tertinggi ditunjukkan pada waktu inkubasi 96 jam dan pH 6, yaitu 83,04%. Hal tersebut membuktikan bahwa Ganoderma sp. dari Kebun Raya Baturraden memiliki waktu inkubasi optimum 96 jam, serta pH optimum 6 untuk mendekolorisasi RBBR.

Batik effluent had high toxicity to aquatic organisms. Dye decolorization is a process used to reduce color density. Fungi which used for decolorization was Aspergillus sp 3. This study aimed to investigate the ability of fungi on decolorization of 3 kinds of batik effluents (Indigosol Green dye, Indigosol Purple dye, and Naphtol Black dye) and to investigate the ability of fungi on reducing TDS level. The study was also investigated the initial toxicity of batik effluents to Goldfish (Cyprinus carpio). Decolorization was measured by spectrophotometry, the pH value was measured by pH meter, and the TDS value was measured by TDS meter. In addition, the decolorized batik effluent was tested for toxic effect on C. carpio by total opercular beats. Decolorization assay showed that Aspergillus sp. 3 had the ability to decolorized only 2 kinds of batik effluents. The decolorization percentage of Indigosol Purple was 60.015% and Naphtol Black was 56.679%. The pH after treatment decreased from 8.5–9 to 5.3–6. The range of pH value of Indigosol Green, Indigosol Purple, and Naphtol Black 5.3–6. Besides that, Aspergillus sp. 3 also had the ability to reduce the TDS level in the effluent. The TDS level on Indigosol Green, Indigosol Purple, and Naphtol Black as 4,965%, 25,307%, and 15,129%, respectively. Initial toxicity assay of effluent to C. carpio showed that there was a difference of total opercular beats, which exposed by decolorized and before decolorized batik effluent. The total opercular beats of C. carpio on decolorized batik effluents showed high value than before decolorized batik effluents. It can be concluded that Aspergillus sp. 3 had the ability to decolorize and decreasing the initial toxicity of Indigosol Purple batik effluents on C. carpio.
