Abstract

Alcohol factory waste which still contains a number of nutrients when enriched with manure is good enough to increase the growth and yield of chili. This research was conducted in Jengglong, Jatisobo Village, Polokarto District, Sukoharjo Regency which took place from September 2019 to January 2020. This study used a completely randomized design with two factors and three replications. The first factor consists of 3 levels of Liquid Organic Fertilizer: waste alcohol + EM4, waste alcohol + EM4 + goat manure, alcohol waste + EM4 + a combination of 3 manure (chicken, goat, cow). The second factor dosage of liquid organic fertilizer consists of 4 levels: 0, 1000, 2000, 3000 l/ha. The results of the study showed that the kind and dosage of liquid organic fertilizer enriched with manure did not significantly affect the growth and yield of chili, but the interaction of the two treatments had a significant effect on the yield of chili. The highest weight of red chili was obtained in the treatment of waste alcohol + EM4 + a combination of 3 manure (chicken, goat, cow) with a dose of 3000 l/ha. In conclusion, the use of alcohol waste for fertilization, especially chili plants, should be combined with manure in order to obtain maximum results. The implication of this research is that for fertilizing chili plants, it is better to use alcohol waste, EM4 and a combination of chicken, goat and cow manure at a dosage of 3000 l/ha.

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.
