“…TSS, COD dan BOD akan menyebabkan terganggunya lingkungan perairan, karena menurunnya kadar oksigen dalam air [5]. Kandungan BOD dan COD pada limbah tahu sebesar 5643 -6870 mg/L dan 6870 -10500 mg/L [6]. Angka BOD dan COD yang tinggi disebabkan karena adanya protein dan zat organik yang terkandung pada limbah tahu.…”

Limbah tahu merupakan zat yang berbahaya dan memiliki dampak buruk terhadap lingkungan apabila tanpa proses pengolahan terlebih dahulu. Permasalahan ini dapat diatasi dengan melakukan pengolahan limbah tahu menggunakan bakteri sebagai alternatif pembuatan pupuk organik dan treatment plasma ozonasi untuk mengurangi bau. Penelitian ini bertujuan untuk menguraikan limbah tahu sehingga dapat digunakan sebagai pupuk organik, mengurangi bau busuk yang dihasilkan oleh limbah tahu sehingga aman dan mudah diterapkan oleh masyarakat. Pengolahan limbah tahu tersebut dilakukan dengan variasi metode menggunakan bakteri pengurai mikroorganisme efektif dimodifikasi dengan plasma ozonasi dan aerator, serta penambahan antifoam. Pengolahan limbah dengan plasma ozonasi didahului dengan penambahan antifoam. Hasilnya menunjukkan limbah dengan penambahan antifoam dan plasma ozonasi selama 15, 30 dan 60 menit memiliki karakteristik sangat bau dan keruh. Penambahan bakteri, molase dengan treatment tanpa dan dengan ozonasi selama 14 hari menunjukkan karakteristik yang agak berbeda dengan bau yang agak berkurang dengan sebelumnya tetapi masih sangat keruh. Penambahan EM4 treatment plasma dikombinasi dengan plasma ozonasi memberikan karakteristik yang paling baik dengan bau dan kekeruhan yang jauh berkurang. Decomposition of Tofu Waste using Bacteria and Ozonation Plasma. Tofu waste is a dangerous substance and had a bad impact on the environment if without not be processed. This problem can be resolved by treating tofu waste using bacteria as an alternative for making organic fertilizers and treating plasma ozonation to reduce odor. The study aims to describe the tofu waste thus it can be used as organic fertilizer, reducing the bad smell produced by tofu waste which is safe and easy for the community to apply. The tofu waste treatment has been treated with a variety of methods using bacteria that decompose microorganisms effectively modified with ozonation plasma and aerators, as well as the addition of antifoam. The waste treatment with ozonated plasma has been processed by the addition of antifoam. The results showed that the waste with the addition of antifoam and ozonation plasma for 15, 30, and 60 minutes had a very odor and cloudy characteristics. The addition of bacteria, molasses treated without and with ozonation for 14 days showed that the tofu wastes have different characteristics with a slightly reduced odor but are still very cloudy. The addition of EM4 plasma treatment combined with ozonated plasma gave the best characteristics with significantly reduced odor and turbidity.

“…Limbah cair yang dihasilkan dari proses pembuatan tahu memiliki kandungan zat-zat organik antara lain 25 -50 % karbohidrat, 40 -60 % protein, 10 % lemak dan padatan tersuspensi lainnya yang dapat berubah menjadi zat toksik (Pradana, Suharno, & Apriansyah, 2018). Apabila limbah tersebut dibuang langsung keperairan, maka akan menyebabkan pencemaran yag dikarenakan adanya pengendapan bahan organik, berkembangannya mikroorganisme dan terganggunya organisme yang berada pada ekosistem perairan.…”

Small and medium industries are experiencing growth every year. The home industry of tofu production is one of the small and medium industries that continues to grow and develop. However, there is a problem if the tofu production waste is disposed of directly into the waters, it will cause pollution due to the deposition of organic material. The research objective was to analyze the subsurface flow-wetlands with plants namely water hyacinth, apu wood and lemna minor to reducing TSS levels and stabilizing pH. This research an experimental with treatments including SSF-Wetlands without water plants (A1), SSF-Wetlands with water hyacinth (A2), SSF-Wetlands with apu wood (A3), SSF-Wetlands with lemna minor (A4) and SSF-Wetlands with water hyacinth, and apu wood (A5). The stages of this research are the sampling stage, the SSF-Wetlands manufacturing stage, the waste treatment stage and the pH and TSS testing stages. Data were analyzed using one-way ANOVA (SPSS 20). The results showed that the liquid waste of tofu in the initial sample was acidic, namely 3.94 and the TSS level was 858 mg / L. The pH condition of the waste after processing by the quality standard. The highest increase in pH and decrease in TSS levels in the tofu liquid waste treatment was the SSF-Wetland processing with water hyacinth plants (A2). This shows that water hyacinth plants have a greater role in neutralizing pH and can absorb the most suspended matter compared to apu wood and lemna minor plants.

“…Amino acids are the main component that causes pollution of water (Sudaryanto, 2006). Another study said that tofu industrial wastewater contains protein (40%-60%), carbohydrates (25% -50%), fat (10%), and other SS, which will produce toxic substances (Pradana, Suharno, & Apriansyah, 2018).…”

“…The results presented indicate that tofu wastewater is above the quality standard, TSS=200; BOD=150; COD=300 (Menteri Lingkungan Hidup, 2014). Therefore, tofu wastewater must be processed before disposed to the environment (Alimsyah & Damayanti, 2013;Ayu Ridaniati Bangun et al, 2013;Herlambang, 2002;Pradana et al, 2018;Puspawati, 2017;Sayow, Tilaar, & Naskah, 2020).…”

“…The primary environmental quality standards are TSS, BOD, and COD (Menteri Lingkungan Hidup, 2014). The high content of pollutants in wastewater causes oxygen levels to decrease, thereby disrupting life in it (Pradana et al, 2018). Poor quality of water will impact reducing the number of biota in the water (Nangin, Langoy, & Katili, 2015;Yogafanny, 2015).…”
