“…The efficiency of biodegradation by bacteria also depends on the ratio between bacterial colonies and the concentration of dye dissolved in the bacterial growth medium (Pinheiro et al, 2022). It is known that bacteria capable of degrading textile dyes have an extracellular matrix (Ahmad et al, 2021) and produce enzymes that can change the chemical structure of pollutants polluted with synthetic dyes to become less complex so that their toxicity level is reduced and become harmless metabolites (Purnamawati et al, 2015).…”

“…According to the Ministry of Investment, the growth of the Textile and Clothing Industry increased significantly by 8.73% from 2018 to 2019 (Ramiayu, 2022). The rapid growth of the textile industry harms the environment in the form of direct disposal of textile dye waste into the environment, in a colored state the waste will be difficult to degrade naturally (Ahmad et al, 2021). This dye waste pollutes the environment which is characterized by changes in O2 and pH levels and inhibition of light penetration in aquatic ecosystems.…”

“…To deal with environmental pollution due to dye waste, biological treatment can be carried out using bacteria (Ahmad et al, 2021). Textile dyes can be decomposed by microorganisms through two methods, either adsorption on microbial biomass or biodegradation of dyes by cells or enzymes.…”

“…Thus, biodegradation is a more practical option (Lellis et al, 2019). Referring to the opinion of (Sa'adah, 2020) and Ahmad et al, (2021) that several bacteria can degrade Rhodamine B because they can produce an extracellular polymeric matrix, namely extracellular polymeric substance (EPS), in response to environmental stress. Some of these bacteria can be found in mangrove ecosystems because they can adapt morphologically, biologically, ecologically, and physiologically to respond to extreme environments under conditions of high salinity, tides, high-temperature pressure, dirt, anaerobic soil, and severe wind pressure.…”

Rhodamine B is a major problem that arises as a result of the development of the textile industry. Rhodamine B is known to be difficult to degrade naturally thus causing a lot of damage, both to the environment and human health such as respiratory tract infection, skin irritation, digestive tract irritation, and eye infection. This study aims to find and determine the type of mangrove root symbiont bacteria Avicennia marina from Panipahan Village that can degrade Rhodamine B. This research is divided into several stages, namely sampling, isolation, purification, characterization of colony morphology, Rhodamine B biodegradation test through the overlay method, gram staining, biochemical tests, and molecular tests to determine the type of bacteria. The results obtained 16 isolates of symbiont bacteria that were successfully isolated from the roots of the Avicennia marina mangrove in Panipahan Village. Of the 16 isolates of symbiont bacteria, only 2 isolates have the potential to degrade Rhodamine B. The results of the biochemical activity test showed positive results in the Catalase, TSIA, motility, and O/F tests on RA5 symbiont bacterial isolates, while the citrate test showed negative results. For RA16 symbiont bacterial isolates, it is known that only the O/F test shows positive results, while the catalase, TSIA, citrate, and motility tests show negative results. The results of bacterial characteristics obtained are that the RA5 symbiont bacterial isolate belongs to the Bacillus circulans type and the RA16 symbiont bacterial isolate belongs to the Bacillus insolitus type. So, it was concluded that there were 2 bacterial isolates of Avicennia marina mangrove root symbionts in Panipahan Village, Riau that were able to degrade Rhodamine B.

“…Industri tekstil di Indonesia berperan penting dalam meningkatkan nilai ekonomi negara yang menjadi orientasi ekspor ke luar negeri dalam memenuhi kebutuhan pasar internasional [1]. Badan Pusat Statistik Indonesia mencatat bahwa kelompok industri tekstil mengalami pertumbuhan secara cepat dari 6,48% pada tahun 2018 menjadi 20,71% pada tahun 2019 [2]. Jumlah produksi industri tekstil mengalami kenaikan yang berakibat pada peningkatan hasil limbah cair sisa proses produksi, sehingga sektor ini menjadi salah satu penyumbang pencemaran terbesar di dunia [3].…”

ABSTRAKRhodamin B merupakan salah satu zat warna dalam limbah cair hasil proses produksi industri tekstil yang dapat berbahaya bagi kesehatan dan menimbulkan pencemaran ketika dibuang ke lingkungan dengan konsentrasi tinggi. Solusi permasalahan tersebut adalah mengurangi konsentrasi Rhodamin B menggunakan metode adsorpsi dengan memanfaatkan bio adsorben salah satunya daun ketapang yang telah diaktivasi terlebih dahulu dengan cara mechanochemical. Mechanochemical merupakan proses pemanfaatan energi mekanik untuk mengaktivasi bahan dan merubah struktur bahan. Penelitian ini bertujuan untuk menganalisis pengaruh waktu aktivasi mechanochemical terhadap kualitas bio adsorben daun ketapang dan pengaruh waktu kontak adsorpsi terhadap daya serap bio adsorben yang dihasilkan. Penelitian ini menggunakan metode kuantitatif dengan variabel tetap perbandingan bio adsorben daun ketapang dengan asam sitrat 1:5 (b/v) dan variabel berubah waktu aktivasi mechanochemical 30; 45; 60 menit dan waktu kontak adsorpsi 90; 120; 150; 180 menit. Analisis yang dilakukan pada pengujian bio adsorben daun ketapang adalah kadar air, daya serap iodium, dan penyerapan Rhodamin B. Hasil analisis terbaik yang diperoleh dari ketiga pengujian tersebut adalah kadar air sebesar 11%, daya serap iodium sebesar 1903,95 mg/g, dan penyerapan Rhodamin B sebesar 92,28 %. Hasil tersebut menunjukkan bahwa daun ketapang dapat digunakan sebagai bio adsorben zat warna Rhodamin B.
