Eco-Enzyme Liquid Fertilizer Trial Using Fruit Peels and Unused Fruit: A Sustainable Agricultural Solution

Abstract

The utilization of organic waste as eco-enzyme liquid fertilizer serves as a strategic solution for waste reduction while providing environmentally friendly plant nutrients. This study aims to evaluate the effectiveness of various fruit peels (pineapple, avocado, dragon fruit, mango, soursop, and banana) as raw materials for eco-enzyme production through a three-month anaerobic fermentation process assisted by Local Microorganisms (MOL). The research method employed a 10:1:3 ratio (water : coconut sugar : fruit peel waste) within a closed fermentation system. The results indicated that the resulting eco-enzyme was physically clear brownish in color with a distinctive fruit fermentation aroma and an acidity level (pH) of 3.5. Application tests on plants showed significant results, where a 10% concentration of the solution increased plant height by 15% and accelerated the emergence of new shoots compared to the control group. These findings confirm that the combination of various tropical fruit peels produces a liquid fertilizer with complex nutritional content effective for supporting vegetative plant growth. This study proves that fruit peel waste can be processed into high-value products that support sustainable agricultural systems.
