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

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

Coastal areas play a strategic role in national development, yet there remains a disparity between their abundant natural resource potential and community well-being. Various environmental issues, such as poor health outcomes, limited access to clean water, and suboptimal waste management, pose obstacles to improving the well-being of coastal communities. Therefore, a sustainable development approach that integrates economic, social, and environmental aspects is needed. This study aims to develop a Green Banking-Based Circular Economy (GBB-CE) model for waste management in Sukolilo Baru Village, Surabaya, as an effort to support the National Economic Recovery (PEN) in coastal areas. The study employed SWOC (Strengths, Weaknesses, Opportunities, and Challenges) analysis to identify strategic factors, as well as content analysis using NVIVO 12 Plus to explore stakeholders’ perspectives on variables supporting the GBB-CE. The results of the SWOC analysis indicate that active community involvement is a key factor in preserving the environment, including through behaviors such as refraining from disposing of waste into the sea or in locations that could potentially pollute the environment. An analysis using NVIVO 12 Plus shows that small and medium-sized enterprises (SMEs) in the capture fisheries sector emphasize optimizing the economic potential of coastal areas, including the utilization of waste, while the Surabaya City Environmental Agency prioritizes waste reduction and environmental conservation.
