Abstract

Eco-enzyme is a liquid produced by utilizing leftover fruits or vegetables with the addition of molasses and water, which are then fermented. This study utilized materials such as orange peel, pineapple peel, and watermelon peel. The objective of this research was to determine the content and the effect of applying eco-enzyme on land spinach plants (Ipomoea reptans Poir.) using a wick hydroponic system. This quantitative experimental research was conducted from January to July 2023 at the Analytical Laboratory of Lampung State Polytechnic and the Integrated Laboratory & Technology Innovation Center of the University of Lampung. The observed parameters included plant height, number of leaves, and leaf length. The study employed a Completely Randomized Design (CRD) with four treatments, one of which served as the control, and each experimental unit was replicated five times. A total of 160 plant samples were used, and measurements were taken every 7 days for a period of 30 days. The data were analyzed for variance and subjected to Tukey's test at a significance level of a = 5%. The research findings revealed that:1) The utilization of eco-enzymes with different treatments has an impact on all observed parameters in the growth of land spinach (Ipomoea reptans Poir.), 2) The best treatment was found in the P4 treatment with an eco-enzyme dose of 6 ml/L.

Abstract

Male betta fish have high commercial value as they are highly favored by many people. Efforts to increase the number of male fish can be carried out through masculinization. This research used a quantitative approach with an experimental method, employing a Completely Randomized Design (CRD) consisting of five treatments and three replications. The highest percentage of male betta fish was obtained in treatment P3, reaching 63.77%, while the lowest percentage was found in the negative control (K-), at 38.75%. Masculinization of betta fish through immersion in Eurycoma longifolia root extract resulted in the highest percentage of male fish when soaked for 8 hours, increasing the sex ratio by 25.02% compared to the untreated control (negative control). Meanwhile, the percentage difference between soaking in Eurycoma longifolia root extract for 8 hours at a concentration of 20 mg/L and administering 17alpha-methyltestosterone for 4 hours at a concentration of 2 mg/L (positive control) was 6.38%. The immersion method with different durations had a significant effect on the percentage of male betta fish. The best soaking duration was found in treatment P1, with a soaking time of 2 hours, resulting in the highest betta fish survival rate of 85% and a male percentage of 62.66%.
