| Abstrak (Bhs. Indonesia) | Limbah degreasing merupakan hasil dari proses pembersihan minyak atau oli mesin menggunakan HCl dan mengandung senyawa berbahaya seperti polycyclic aromatic hydrocarbon (PAH) dan total petroleum hydrocarbon (TPH) yang bersifat karsinogenik. Salah satu metode pengolahan yang ramah lingkungan adalah bioremediasi menggunakan jamur. Penelitian ini memanfaatkan Aspergillus niger dan Aspergillus sp.3 untuk mendegradasi limbah degreasing. Aspergillus niger mampu menghasilkan enzim lignolitik, amilase, selulase, dan protease, sedangkan Aspergillus sp.3 memproduksi enzim lignolitik yang menguraikan lignin. Imobilisasi jamur dilakukan menggunakan abu boiler bagasse tebu (ABBT) yang mengandung lignoselulosa sehingga meningkatkan porositas dan mendukung pertumbuhan jamur. Penelitian ini bertujuan mengetahui pengaruh dan efektivitas Aspergillus spp. terimobilisasi ABBT dalam mendegradasi limbah degreasing dengan variasi konsentrasi 25%, 50%, 75%, dan 100%. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL). Parameter utama yang diamati adalah persentase degradasi limbah, sedangkan parameter pendukung meliputi berat kering biomassa, pH, suhu, kadar DO, dan TDS. Hasil penelitian menunjukkan bahwa Aspergillus spp. terimobilisasi ABBT mampu mendekolorisasi limbah degreasing. Perlakuan dengan konsentrasi limbah 100% memberikan hasil tertinggi, dengan persentase degradasi 88,46% oleh Aspergillus sp.3 terimobilisasi ABBT. Berat kering biomassa berkisar antara 3,37–10,04 g, pH 1,49–4,16, DO 2,12–9,20 mg/L, TDS 1203–4830 mg/L, dan suhu 28–30°C. |

| Abtrak (Bhs. Inggris) | Degreasing waste, generated from cleaning oil or grease from machinery using hydrochloric acid (HCl), contains recalcitrant compounds such as polycyclic aromatic hydrocarbons (PAHs) and total petroleum hydrocarbons (TPH), which are carcinogenic and harmful to the environment. Bioremediation using fungi offers an environmentally friendly solution. This study utilized Aspergillus niger and Aspergillus sp.3 to degrade degreasing waste. Aspergillus niger produces ligninolytic, amylase, cellulase, and protease enzymes, while Aspergillus sp.3 produces ligninolytic enzymes that degrade lignin. Fungal degradation was enhanced using sugarcane bagasse boiler ash (ABBT) as an immobilization material, as it contains lignocellulose that increases substrate porosity and supports fungal growth. The research aimed to determine the effect and effectiveness of Aspergillus spp. immobilized on ABBT in degrading degreasing waste at various concentrations (25%, 50%, 75%, and 100%), using a Completely Randomized Design (CRD). The experiment began with fungal inoculum preparation, followed by immobilization on ABBT and subsequent degradation tests. The independent variables were fungal species and waste concentration, while the dependent variable was the degradation efficiency. Results showed that Aspergillus spp. immobilized on ABBT effectively decolorized and degraded degreasing waste. The highest degradation percentage (88.46%) was achieved by Aspergillus sp.3 immobilized on ABBT at 100% waste concentration. Supporting parameters included the dry weight of immobilized fungi (A. niger: 5.74–10.04 g; A. sp.3: 3.37–6.20 g), pH (1.49–4.16), dissolved oxygen (2.12–9.20 mg/L), total dissolved solids (1,203–4,830 mg/L), and temperature (28–30°C). |
