Abstract

The increasing environmental concerns associated with synthetic plastics have driven the search for biodegradable alternatives. This study investigates using sweet corn cob waste (Zea mays L. saccharata) for bioplastic production with varying concentrations of zinc oxide (ZnO) and glycerol as additives. The objective is to evaluate the influence of these additives on the mechanical properties, functional group composition, and biodegradability of the resulting bioplastics. The experimental procedures involved the delignification of corn cobs, bioplastic synthesis, and subsequent characterization through Fourier Transform Infrared Spectroscopy (FTIR), tensile strength and elongation tests, and biodegradability assessments. The results showed that increasing ZnO concentrations improved tensile strength, with the highest recorded at 9% ZnO and 25% glycerol. However, increased ZnO reduced elongation and biodegradability due to increased material stiffness. Conversely, higher glycerol concentrations enhanced flexibility and biodegradability but decreased tensile strength. The optimal formulation was identified at 3% ZnO and 35% glycerol, which provided a balanced combination of mechanical strength and biodegradability. This study demonstrates the potential of sweet corn cob waste as a sustainable raw material for bioplastics, contributing to environmentally friendly alternatives to conventional plastics.

Abstract

This growing need for sustainable agriculture has made using recycled waste material in plant cultivation a significant area of research. The tofu industry, as a leading producer of nitrogen (N), phosphorus (P), and potassium (K)-rich wastewater, is a valuable substrate resource for microbial fermentation. The application of solid-state fermentation using EM4 with coconut water under aerobic and anaerobic processes works towards acidification of DM, increasing bioavailable nutrients and minimizing environmental implications from untreated wastewater discharge. This study determined the feasibility of fermenting tofu wastewater with coconut water and EM4 to produce liquid organic fertilizer and analyzed the product’s N, P2O5, K2O, C-organic, and C/N ratio. Fermentation occurred at 4:1 of tofu wastewater: fermentation materials, with EM4 concentrations of 10%, 25%, and 50% under anaerobic conditions for 14 days. The fertilizer produced was analyzed and compared with liquid organic health fertilizer according to nonstandard percent by Minister of Agriculture no. 70/Permentan/SR.140/10/2011. Results showed that fermentation increased tofu wastewater’s protein and amino acid contents. The highest nitrogen content (3.09 ± 0.023%) was obtained by treatment C (50% EM4), meeting standard requirements (3-6% N). The K2Oconcentration of treatment C peaked at 3.28 ± 0.025% (K2O) within the acceptable range (3-6% K2O). The C-organic content in treatment C reached 10.5 ± 0.094%, exceeding the minimum quality (6%). The P2O5 contents never exceeded the maximum limit (2.22 ± 0.0057%). Although it indicates a rapid-acting fertilizer, the C/N ratio remained low for all treatments.

Abstract

The most common problem encountered in the use of well water is the presence of metal contaminants, particularly iron (Fe) and manganese (Mn). One alternative solution is the use of filtration with zeolite and activated carbon. This research aims to improve the quality of well water by reducing Fe, Mn, and turbidity levels using filtration technology. The treatment reactor consists of two reactors with the difference between reactors 1 and 2 lies in the type of media used. Reactor 1 uses zeolite media, and reactor 2 uses activated carbon. The filtration column used is a PVC pipe with a diameter of 10 cm and a length of 1 m. The independent variable in this study is the composition of the filtration media, consisting of a combination of quartz sand-zeolite and quartz sand-activated carbon. The research findings show that in reactor 1, the decrease in Fe levels from the first day to the third day is 0.4975 mg/L, 0.6175 mg/L, and 0.605 mg/L, whereas in reactor 2, it is 0.9175 mg/L, 0.7725 mg/L, and 0.685 mg/L. The decrease in Mn levels in reactor 1 over three consecutive days is 0.08 mg/L, 0.07 mg/L, and 0.05 mg/L, while in reactor 2, it is 0.12 mg/L, 0.09 mg/L, and 0.06 mg/L. The decrease in turbidity levels in reactor 1 consecutively is 20.825 NTU, 13.305 NTU, and 11.09 NTU, while in reactor 2, it is 21.4775 NTU, 18.36 NTU, and 12.23 NTU. These filtration results have met the clean water quality standards according to PERMENKES No. 32 of 2017.

Abstract

Tofu industry waste pollution is still a serious problem. The high burden of tofu industrial waste pollutants is still a major problem. besides, the unavailability of the budget for processing and the limitations of a cheap and efficient treatment system are factors supporting the pollution of tofu waste in the environment. This study examines the efficiency of reducing BOD5 and COD treated with constructed wetlands using water jasmine plants (Enchinodorus palaefolius). The system used is the wetland subsurface with continuous flow. The media used include sand and biochar with a residence time of 12 hours 18 hours. Whereas pH, temperature, and flow rate are conditioned as control variables. The greatest efficiency of BOD5 and COD occurs in reactors using biochar media and a residence time of 18 hours with an efficiency of BOD5 of 50.52% and COD of 55.02%.

Abstract

Tofu industrial wastewater is a contributor to environmental pollution. Wastewater contains high levels of COD and TSS. The purpose of this study was to determine the effectiveness of reducing pollutant loads in tofu liquid waste by using the phytoremediation method using water jasmine (Echinodorus Palaefolius). The initial stage of the research was a preliminary test to determine the initial content of the waste. The acclimatization process is carried out by observing the process of plant growth during the research process. To maximize plant growth, dilution is carried out with various concentrations of 25% wastewater with 75% diluting water and 50% wastewater with 50% diluting water. Sampling was carried out every 12 hours for 5 days. The results showed that the highest effectiveness of COD reduction occurred in RFT 25% with a residence time of 12 hours at 39.83%, while for TSS parameters the highest effectiveness was at RFT 25% with a residence time of 12 hours by 69%.
