“…Pengelolan limbah budidaya tambak untuk mengurangi kandungan bahan organik yang aman bagi lingkungan dan efisien adalah dengan mengembangkan sistem bioremediasi (Lukwambe et al, 2019). Bioremediasi adalah penggunaan agen biologi untuk mengurangi kontaminasi organik ke tingkat yang aman bagi lingkungan.…”

Air limbah budidaya udang setelah akhir masa pemeliharaan memiliki kandungan bahan organik total (TOM) yang tinggi sampai 87.74 mg/L. Apabila air limbah tersebut dibuang secara langsung tanpa upaya penurunan atau pengolahan, akan mengganggu ekosistem perairan umum karena tingginya bahan organik tersebut. Tujuan dari penelitian ini untuk mengetahui kecepatan penurunan bahan organik pada limbah budidaya tambak. Penelitian dilaksanakan pada bulan Januari 2021. Air sampel limbah tambak diambil dari tambak pada masa akhir pemeliharan (120 hari pemeliharaan). Jenis merek dagang konsorsium bakteri yaitu EM 4 , Bio HS, BIO Prisma, Starbio plus, BIO2000, dan Biolet. Penelitian eksperimen disusun dalam rancangan Acak Lengkap 6 perlakuan dan 4 ulangan. Masing-masing perlakuan diisi 2 liter air limbah ditambah 6 ml konsorsium bakteri yang berbentuy cair. Sedangkan untuk konsorsium bakteri yang padat di tambahakan 1 gram/L. Pengukuran bahan organik total, suhu, pH, oksigen terlarut, salinitas dan karbondioksida dilakukan setiap 24 jam selama 72 jam pengamatan. Hasil penelitian menunjukan selama 72 jam perendaman persen penurunan bahan organik tertinggi pada perlakuan E (BIO 2000) sebesar 95 % (87,74 mg/L menjadi 4,11 mg/L). Persen penurunan terendah pada perlakuan D (Starbio plus) sebesar 83,4% (87,74 mg/L menjadi 14,54 mg/L). Namun, secara umum 6 jenis merek dagang konsorsium bakteri dapat menurunkan bahan organik. Kadar suhu, pH, oksigen terlarut dan salinitas dalam kondisi optimum, sedangkan karbondioksida melebihi ambang batas yang disebabkan oleh tingginya aktivitas perombakan bahan organik oleh bakteri. Kesimpulan yang diperoleh merek dagang konsorsium bakteri BIO2000 paling efektif dalam menurunkan bahan organik selama 72 jam.

“…Wetland rhizospheres are essentially oxic-habitats or niches created by the roots' aeration and can markedly affect the diversity of the wetland's heterotrophic biota [14]. Wetlands can influence water and/ or sediment physicochemical properties through different mechanisms including microbial OM mineralization, sedimentation and substrate-adsorption processes [9,15].…”

“…The physical nature of biofilm exopolymers has a great adsorptive capacity with a super binding affinity for nutrients [17]. Biofilms can contribute substantially to nutrient cycling, organic matter degradation, and community enrichment due to bacteria mineralization [9,18,19]. Sedimentation is the physical process by which suspended material such as clay, silts and other organic particles found in the water settle by gravity.…”

“…The strength and efficacy of the constructed wetland and biofilm treatments are supported by the consortium of bacterial communities [9,26]. Thus, exploring the relationship between biological treatment methods such as constructed wetlands and biofilms on bacterial community and sediment properties is imperative.…”

Constructed-wetlands, Biofilms, and sedimentation are potential aquaculture tail-water treatments however their roles on the distribution of benthic microbial community and the way they affect the interaction between microbial community and inorganic nutrient fluxes have not been fully explored. This study applied 16S rRNA high-throughput sequencing technology to investigate the microbial community distribution and their link with nutrient fluxes in an aquaculture tail- water bioremediation system . Results showed that bacterial community compositions were significantly different in constructed-wetland and biofilm treatments (p<0.05) relative to sedimentation. The composition of the 16S rRNA genes among all the treatments was enriched with Proteobacteria, Bacteroidetes, Firmicutes, and Flavobacteria . NMDS analysis showed that the bacterial composition in constructed-wetland and biofilm samples clustered separately compared to those in sedimentation. The Functional-Annotation-of-Prokaryotic-Taxa analysis indicated that the proportions of sediment-microbial-functional groups (aerobic-chemoheterophy, chemoheterotrophy, and nitrate-ammonification combined) in the constructed-wetland treatment were 47%, 32% in biofilm and 13% in sedimentation system. Benthic-nutrient fluxes for phosphate, ammonium, nitrite, nitrate and sediment oxygen consumption differed markedly among the treatments ( p<0.05 ). Canonical correspondence analysis indicated constructed-wetland had the strongest association between biogeochemical contents and the bacterial community relative to other treatments. This study suggests that the microbial community distributions and their interactions nutrient fluxes were most improved in the constructed-wetland followed by the area under biofilm and sedimentation treatment.
