Abstract

Biodegradasi dapat menjadi salah satu teknologi pengolahan air limbah yang aman dan berwawasan lingkungan. Secara alamiah, bakteri yang berpotensi dalam proses biodegradasi dapat diisolasi dari limbah itu sendiri. Bakteri inilah yang disebut sebagai bakteri indigen. Sungai Badheg di kota Malang merupakan salah satu sungai yang tercemar limbah pabrik kulit. Hasil uji kualitas air dari sampel menunjukkan kondisi yang tidak memenuhi baku mutu air, yaitu TSS sebesar 400 ppm, BOD sebesar 331 mg/L, COD sebesar 544 mg/L, DO sebesar 3,6 mg/L dan kadar lemak sebesar 280 mg/L. Limbah pabrik kulit memiliki karakteristik yang berbau tajam, berwarna hitam pekat, dan mengandung lemak dalam jumlah yang besar. Lemak diketahui sebagai salah satu bahan organik yang sulit untuk diuraikan secara alamiah. Peran bakteri indigen akan mengoptimalkan proses biodegradasi lemak yang terjadi. Kegiatan biodegradasi dilakukan dengan cara mengintroduksi bakteri indigen yang telah diseleksi dari proses isolasi dan memiliki potensi pendegradasi paling tinggi, kemudian dikultur dan diinokulasikan kembali pada sampel air, sehingga proses transformasi akan berlangsung lebih optimal. Hasil biodegradasi secara in vitro menggunakan bakteri indigen, menunjukkan perubahan TSS sebesar 293ppm, BOD 117 mg/L, COD sebesar 165 mg/L, DO sebesar 19 mg/L dan kadar lemak sebesar 0,02 mg/L. Biodegradasi merupakan cara yang efektif dalam mendegradasi bahan organik, terutama kadar lemak.

Abstract

Heavy metals have been used in various areas around the world especially in the industrial sector. Heavy metals contamination is very dangerous for ecosystem because of its toxicity for some organisms. Cadmium (Cd) is a dangerous metal pollutant that can cause remarkable diverse of toxic effects, in particular for humans and animals. The use of bacteria as bioremediation agents has been widely studied because more efficient, less cost, and environmentally friendly strategy. This present study aimed to isolate and identify Cd-resistant bacteria from the industrial disposal site. Wastewater samples were collected from disposal site of agar flour industry in Lawang Malang, East Java. The collected wastewater effluent was analyzed for physicochemical properties. Isolation of Cd-resistant bacteria was carried out using serial dilution. Bacterial isolates were observed and tested for their effects on the content of Cd. The content of Cd was tested daily using Atomic Absorption Spectroscopy (AAS) for seven consecutive days. Data was analyzed using one-way ANOVA (p < 0.05) and Tukey test. Characterization of potential bacterium was performed using bacterial identification kit. Four bacteria isolates have been successfully isolated from the wastewater sample. There was a statistically significant difference between groups as determined by one-way ANOVA (F = 1229.62, p = 0.00). A Tukey post hoc test revealed that all conditions are significantly different from each other. The content of Cd in wastewater sample was statistically significantly lower after taking the A isolate (3.39 mg/L, p = 0.00), B Isolate (1.47 mg/L, p = 0.00), C Isolate (1.15 mg/L, p = 0.00), and D isolate (1.95 mg/L, p = 0.00) compared to the control treatment (5.11 mg/L, p = 0.00). Two of the most potential isolates identified as Pseudomonas flourescens (C isolate) and Enterobacter agglomerans (B isolate).
