Abstract

High amounts of black liquor wastewater are generated from bioethanol production by using oil palm empty fruit bunches. It contains an alkaline solution (NaOH), so it is quite toxic for aquatic ecosystems if discharged directly into waters. Black liquor has been treated by coagulation method, and it still needs additional treatment. This study aimed to determine degradation of black liquor wastewater by selected white-rot fungi (WRF). Five different strains of WRF have been tested for their ability to decolorize black liquor on agar and liquid media. Out of five fungi studied, two fungi, Ceriporiopsis sp. and Phanerochaete chrysosporium, showed the capacity to grow more than 50% on agar medium. In liquid medium, the percentage of decolorization of 15,000 ppm coagulated and diluted black liquor ranged from 70 to 89% at 30 days depending on the fungal strain. Ceriporiopsis sp. showed the better ability to decolorize black liquor than P. chrysosporium. The performance of Ceriporiopsis sp was evaluated regarding decolorization of black liquor, chemical oxygen demand (COD), and mycelial dry weight both in coagulated black liquor and original black liquor. The color of original and coagulated black liquor can be decolorized up to 90.13 and 86.85%, respectively. COD in original and coagulated black liquor was reduced up to 70.17 and 40.09%, respectively. The presence of coagulant Poly Aluminum Chloride (PAC) inhibited degradation of black liquor by fungus. The result demonstrated that Ceriporiopsis sp has a potential alternative to treat black liquor wastewater.

Abstract

Dimethyl phthalate is one of the main chemicals in the manufacture of plastics which is harmful to human health because it can be easily absorbed in the body through the skin and is toxic so it is necessary to do a waste treatment process. Adsorption is an alternative method for reducing the levels of dimethyl phthalate in liquid waste. The purpose of this study was to determine the effect of adsorption efficiency on dimethyl phthalate using a composite activated carbon from black liquor-diatomite. A composite activated carbon from black liquor-diatomite were contacted with dimethyl phthalate using the batch method at 120 minutes contact time at 30°C and pH 5, the variations tested were the concentration and dosage adsorbent. Testing samples using GC-MS. The results showed optimum dimethyl phthalate adsorption at a concentration of 1 ppm with a contact time of 120 minutes, an adsorbent dose of 0.05 gram and a pH of 5 at 64.2%.

Abstract

Indigosol Blue merupakan salah satu zat warna sintetik Antraquinon yang digunakan sebagai pewarna biru pada industri pencelupan tekstil dan bersifat rekalsitran dan non-biodegradable, sehingga tidak mudah rusak oleh perlakuan kimia maupun fotolitik. Isolat Trametes sp. diyakini memiliki kemampuan mentransformasi komponen pewarna melalui mekanisme degradasi enzimatik. Trametes sp. mampu menghasilkan enzim ekstraseluler ligninolitik yang dapat mendegradasi komponen xenobiotik dalam limbah pewarna indigosol menjadi bentuk yang tidak toksik di lingkungan. Penelitian bertujuan untuk mengetahui kemampuan tiga isolat uji dalam menghasilkan enzim dalam pewarna Indigosol Blue pada konsentrasi glukosa berbeda serta mengetahui isolat dengan konsentrasi glukosa optimum yang memiliki aktivitas enzim terbaik dalam pewarna Indigosol Blue. Pengukuran aktivitas enzimatik dilakukan dengan metode spektrofotometri. Hasil penelitian menunjukkan bahwa isolat-isolat uji dapat menghasilkan enzim dalam pewarna Indigosol Blue pada konsentrasi glukosa berbeda. Aktivitas enzim pada masing-masing perlakuan berbeda-beda dan menunjukkan hasil yang signifikan. Data uji lanjut memperlihatkan bahwa isolat Trametes sp. strain A memiliki aktivitas enzim terbaik dalam pewarna Indigosol Blue dengan konsentrasi glukosa 0,5%.

Abstract

The use of plastic in Indonesia, especially as packaging, is very popular among the public, because it is practical and has many uses. Plastic consumption in 2020 even reached 67.8 million tons per day. Therefore, one way to overcome this problem is to use and produce biodegradable plastics or bioplastics. Biodegradation of bioplastics can be done with fungi. The potential place to find bioplastic degrading fungi is the Gunung Tugel Ex-Final Disposal Site (TPA). Considering the fact that bioplastics have a fairly good level of degradation, in this study a starchbased biodegradation test will be carried out using isolates of indigenous fungi originating from Ex-TPA Gunung Tugel using the method of calculating the weight loss of bioplastics (weight loss). This study aims to obtain starch-based bioplastic degrading fungi isolates from Ex-TPA Gunung Tugel, Banyumas Regency and determine the highest biodegradability ability of starchbased bioplastics by fungal isolates from Ex-TPA Gunung Tugel, Banyumas Regency. The results showed that isolates of indigenous fungi that had the potential to degrade starch-based bioplastics from Ex-TPA Gunung Tugel, Banyumas Regency were obtained from the genus Aspergillus (GT2 isolate) and Penicillium (GT1, GT3, GT4, GT5, and GT6) isolate. The highest biodegradability of starch-based bioplastics was found by fungi from the genus Aspergillus, namely, isolate GT2 with a weight loss of 21.84%. The biodegradation occurs due to the activity of endoamylase, exoamylase, and glucanase enzymes produced by fungi. The observation of the texture of the bioplastic resulted in a significant change in color, namely from the white bioplastic sheet to brownish. These observations also showed the attachment of fungal mycelium on the surface of the bioplastic accompanied by a hollow and uneven surface of the bioplastic. Key words: Biodegradation, Starch-based bioplastic, Indigenous Fungi, TPA.
