The Effectiveness of Using Ecoenzyme

This study aims to identify microbes contained in rhizome waste ecoenzymes and analyze their effects on the growth of green lettuce (Lactuca sativa L.). The method used was an experiment with a Completely Randomized Design (CRD) design involving four ecoenzyme treatments at concentrations of 0%, 10%, 20%, and 30%, and six repetitions. The effect of ecoenzymes was tested on plant growth parameters, namely weight, height, and number of leaves. The data obtained were analyzed using normality tests, homogeneity tests, ANOVA, and Duncan to determine significant differences between treatments. The results showed that rhizome waste ecoenzymes contained Bacillus subtilis microbes that played a role in increasing the growth of green lettuce plants. The treatment of 20% ecoenzyme (T2) gave the best effect on increasing plant weight (69.83 grams), plant height (48.32 cm), and number of leaves (21.50 strands). Climatic factors such as soil pH showed stability that supported microbial activity, with an average pH of 4.5 across all treatments. Overall, rhizome waste ecoenzymes can be an effective alternative organic fertilizer in increasing the growth of green lettuce plants. Keywords: Ecoenzyme, Rhizome Waste, Microbes, Green Lettuce.
