Abstract

Remazol Brilliant Blue R (RBBR) merupakan pewarna yang banyak digunakan di industri tekstil, namun termasuk limbah cair yang berbahaya bagi lingkungan dan manusia. Biodegradasi oleh jamur menjadi salah satu metode pengolahan limbah pewarna yang efektif dan ramah lingkungan. Penelitian ini bertujuan untuk menganalisis potensi isolat jamur laut asal pesisir Balikpapan dalam mendegradasi pewarna RBBR serta mengevaluasi pengaruh kombinasi pH dan sumber nitrogen terhadap kemampuan degradasi pewarna RBBR. Metode penelitian yang digunakan meliputi kuantitatif dan kualitatif yang dianalisis secara deskriptif dan MANOVA dua arah serta MANOVA tiga arah. Hasil penelitian dari 12 isolat jamur laut diperoleh dua isolat jamur yang menunjukkan kemampuan mendegradasi pewarna RBBR, yaitu FMA6 dan FMA7. Hasil MANOVA dua arah menunjukkan waktu inkubasi berpengaruh nyata terhadap persentase degradasi pewarna RBBR. Hasil uji DMRT menunjukkan persentase degradasi pewarna RBBR oleh FMA6 dan FMA7 (73,60%) pada waktu inkubasi 28 hari. Hasil analisis MANOVA tiga arah menunjukkan bahwa interaksi jenis isolat, waktu inkubasi, serta kombinasi pH dan nitrogen berpengaruh nyata terhadap persentase degradasi pewarna RBBR. Hasil uji DMRT menunjukkan degradasi pewarna RBBR tertinggi dicapai pada perlakuan ammonium nitrat pH 7 oleh FMA6 (66,30%) dan FMA7 (66,48%) selama 28 hari inkubasi. ***** Remazol Brilliant Blue R (RBBR) is a dye widely used in the textile industry, but it is classified as a hazardous liquid waste that is harmful to the environment and humans. Biodegradation by fungi is one of the most effective and environmentally friendly methods of treating dye waste. This study aims to analyze the potential of marine fungal isolates from the Balikpapan coast in degrading RBBR and to evaluates the effect of pH and nitrogen source combinations on RBBR degradation capacity. The research methods used include quantitative and qualitative analyses, which were analyzed descriptively and using two and three-way MANOVA. The results of the study on 12 marine fungal isolates identified two fungal isolates capable of degrading RBBR dye, namely FMA6 and FMA7. The two-way MANOVA results indicated that incubation time significantly affected the percentage of RBBR dye degradation. The DMRT test results showed that the percentage of dye degradation by FMA6 and FMA7 (73.60%) occurred at an incubation time of 28 days. The three-way MANOVA analysis results indicated that the interaction between isolate type, incubation time, and the combination of pH and nitrogen significantly influenced the percentage of RBBR dye degradation. The DMRT test results showed that the highest RBBR dye degradation was achieved in the ammonium nitrate pH 7 treatment by FMA6 (66.30%) and FMA7 (66.48%) during 28 days of incubation.
