Abstract

Organic waste management is becoming increasingly important in responding to current global environmental challenges. In this context, this community service aims to explore the potential for using organic waste as a substrate for hydroponic media in building a greener agricultural future in a sustainable system. The use of organic waste as a substrate for hydroponic media has great potential in supporting plant growth, because it contains available N, P2O5, K2O and C-organic nutrients which are sufficient for plant growth and development. Plants grown in organic waste-based substrates show comparable or even better growth compared to plants grown in conventional substrates. The use of organic waste in hydroponic farming also has a positive impact on the environment. More effective management of organic waste helps reduce environmental pollution and greenhouse gas emissions. This community service program has also succeeded in increasing public awareness and knowledge about organic waste management and hydroponic technology. Thus, the use of organic waste as a substrate for hydroponic media offers great potential in improving organic waste management, increasing agricultural productivity, and reducing negative impacts on the environment. This activity makes a real contribution to building a more sustainable agricultural future and contributes to global efforts in facing increasingly complex environmental challenges.

Abstract

The valorization of agro-food waste represents a promising pathway toward sustainable bio-based materials. This study aimed to formulate a fermentation medium from rice panicle straw (merang) and watermelon rind for producing eco-friendly SCOBY (Symbiotic Culture of Bacteria and Yeast) biofilm. The waste materials were thermally extracted without filtration to retain active solids and subsequently fermented with lactic acid bacteria for 14 days. The fermentation broth was enriched with soybean flour as a nitrogen source and Ziziphus mauritiana leaf extract as an antioxidant additive. Phytochemical screening was conducted using colorimetric reactions analyzed through chromaticity coordinates for flavonoids and grayscale intensity for alkaloids. SCOBY growth was evaluated by measuring biofilm thickness, wet and dry weight, tensile strength, and elongation at break. The results revealed that the combination of these residues provided sufficient nutrients and bioactive compounds to support SCOBY development. The best treatment produced a biofilm with 4.51 mm thickness, 17.49 g wet weight, 3.86 g dry weight, 43.11 MPa tensile strength, and 6.66% elongation. Colorimetric evaluation showed a red chromaticity spectrum for flavonoid presence (dominant wavelength 620 – 625 nm, purity 81.04%), and a clear white grayscale range (220 – 240) for alkaloids. In conclusion, this formulation offers a simple, low-cost approach to converting agricultural waste into functional biofilms. Further investigations are recommended to evaluate the shelf life and potential of liquid SCOBY as a plant immunomodulator and biofilm as organic packaging.
