“…After a perfect fermentation process, eco-enzymes (dark brown liquids) are formed. Eco-enzyme liquids can be used as versatile cleaning fluids such as hand sanitizers and disinfectants in addition eco-enzymes can be utilized as insecticides, and dregs from eco-enzymes can be used as organic fertilizers [14] [15].…”

Eco-enzyme is a multifunctional liquid produced from fermentation of waste or organic waste, brown sugar or granulated sugar, and water. Fermentation of eco-enzymes is carried out for ±3 months. The length of time fermentation affects color, aroma and pH. The resultingeco-enzyme liquid is dark brown and has a strong fresh sour aroma. Eco-enzymeliquid has an alcohol content and acetic acid. Alcohol and acetic acid are produced from the bacterial metabolic process that is naturally present in the rest of fruits and vegetables. Variations in the fermentation time of eco-enzymes used are 2.5 months and 3 months. Analysis conducted on eco-enzymes include pH tests and phytochemical screening tests. The pH value obtained in eco-eznyme 2.5 months is 3, while the pH value in eco-eznyme 3 months is 1.5. Eco-enzymes with a fermentation time of 3 months contain alkaloid compounds, flavonoids, saponins, and tannins. In this study Eco-eznyme was used as a hand sanitizer spray by diluting the eco-enzyme with aquadest. The dilution ratios used vary for each sample: 1:40, 2:40, 3:40, 4:40, 5:40. Analysis conducted on hand sanitizer spray include pH test, organoleptic test, and antibacterial activity test. Based on the results of the analysis, not all hand sanitizer samples meet SNI standards, the best samples obtained in hand sanitizer with an eco-enzyme fermentation time of 3 months and a dilution ratio of 5: 40. The results of the analysis showed that the value of pH 5, the level of aroma fondness in hand sanitizer 2.40, the favorite color level 2.46

Tahu merupakan makanan yang digemari di Indonesia dan industri tahu merupakan salah satu industri yang cukup potensial untuk dikembangkan. Tingginya konsumen tahu membuat industri tahu semakin banyak bermunculan, namun dengan bertambahnya industri tahu juga akan berdampak menghasilkan limbah yang lebih banyak. Salah satu limbah yang dihasilkan dari industri tahu adalah limbah cair. Limbah cair industri tahu mengandung COD, BOD, pH dan TSS yang tinggi dan jika langsung dibuang ke sungai tanpa melalui proses pengolahan terlebih dahulu akan mengakibatkan penunuran kualitas sungai tersebut. Sehingga perlu adanya pengolagan limbah industri tahu dengan menggunakan metode media filter adsorben alam dan metode elektrokoagulasi. Dari hasil pengolahan limbah cair industri tahu terdapat penurunan kadar yang cukup signifikan dengan menggunakan metode media filter adsorben alam menghasilkan kada BOD sebesar 784 mg/L, COD sebesar 2166 mg/L, pH sebesar 5, dan TSS sebesar 460 mg/L. Pada metode elektrokoagulasi mendapatkan hasil variasi teganga optimum yang berbeda pada tiap parameter yaitu BOD sebesar 1701 mg/L dengan tegangan 20 volt, COD sebesar 533 mg/L dengan tegangan 20 volt, pH sebesar 7 dengan tegangan 30 volt dan TSS sebesar 400 mg/L dengan tegangan 30 volt.

“…One alternative to wastewater treatment is electrocoagulation. The electrocoagulation process is an electrochemical method for water treatment where at the anode there is a release of active coagulants in the form of metal ions (usually aluminum or iron) into the solution, while at the cathode there is an electrolytic reaction in the form of the release of hydrogen gas [10][11][12][13]. The electrocoagulation process is influenced by several factors including electric current, electric voltage, contact time, temperature, pH, and conductivity.…”

Tofu waste liquid contains high levels of organic impurities, such as protein and amino acids. These organic compounds cause the tofu industrial wastewater to contain high biological oxygen demand (BOD), chemical oxygen demand (COD), pH and total suspended solid (TSS) which can pollute the environment. In general, the liquid waste from the tofu factory is discharged directly into rivers through sewers and rivers. Most of the tofu wastewater contains various kinds of pollutants which may be produced in the form of organic pollutants (foul smelling), inorganic pollutants (spicy and colored), so they are dangerous to the surrounding environment and need to be treated. One alternative to tofu liquid waste treatment is electrocoagulation. The electrocoagulation method has the potential to purify tofu wastewater and reduce the content of BOD, COD, TSS and neutralize pH without the addition of certain chemical coagulants. The purpose of this study was to obtain the characteristics and levels of pollutants contained in tofu industrial wastewater before and after processing, and to determine the effectiveness of the electrocoagulation method with various variations in voltage and reaction time. The electrocoagulation tub is attached with a cable connected to the power supply, then connected to a current source with a variable voltage (8; 10; 12 V) and a variable reaction time (30; 60; 90; 120; 150 minutes). The optimum conditions were obtained at a voltage variation of 12 volts and a reaction time of 150 minutes, with a percentage increase in pH of 72.33% to 5.98, a decrease in COD of 28.57% to 10 mg/L, a decrease in BOD5 of 46.87% to 2, 29 mg/L, and TSS from 11.47% to 21.6 mg/L.
