Abstract

Spinach is one of the most common types of green plants in Indonesia. This one plant is a type of vegetable that is easily processed for everyday food, from soup, pecel, gado-gado (Indonesian food), also chips. Amaranthus viridis also known as spinach pull out. In this study, observed the growth of spinach plants with ecoenzyme treatment. The treatment groups were: A (1.5% ecoenzyme), B (3% ecoenzyme), C (4.5% ecoenzyme), D (6% ecoenzyme), E (control/without treatment), F (NPK/ chemical fertilizer). Parameters observed were height, stem diameter, number of leaves, leaf diameter, wet weight and color. This type of research is experimental research and ANOVA data analysis techniques. The duration of the study was 27 days with 9 scheduled observations. Measurements were made in the afternoon, with reference to the observation parameters of stem height, leaf diameter, number of leaves, leaf diameter, leaf color and wet weight. The results of the observations showed that the ecoenzyme treatment was no better than the control and the NPK fertilizers showed that the height, stem diameter, number of leaves, leaf diameter, wet weight and color tended to be smaller. The conclusion of giving ecoenzymes at doses of 1.5%, 3%, 4.5% and 6% does not accelerate and tends to inhibit the growth of spinach (Amaranthus viridis).

Abstract

This research was carried out from November to December 2023, at the Ruyani Life Sciences Learning Resources (SBIH). The aim of this research was to determine the effect of feeding tofu dregs and cow dung on the growth of earthworms (Lumbricus rubellus). The method used in this research was an experimental method, namely a Completely Randomized Design (CRD) with 6 feed treatments + 3 repetitions for continuation of undergraduate student research and 6 feed treatments + 3 repetitions for initiation. Data analysis used the Kruskall-Wallis nonparametric statistical test with Asymp. Sig. values. ≤ 0.05, and continued with the Mann-Whitney test. The research results show that the value of Asymp. Sig. parent biomass, offspring biomass, number of parent individuals, and number of Lumbricus rubellus offspring in sequence, in the 1st to 4th week of follow-up research Asymp. Sig. values. namely 0.086; 0.036; 0.140; and 0.064. In the 5th to 8th week of further research, the Asymp. Sig. value. namely 0.168; 0.047; 0.176; and 0.095. And in the 5th to 8th weeks of the research, the Asymp. Sig. value was initiated. namely 0.062; 0.010; 0.434; and 0.013. The conclusion was that feeding tofu dregs and cow dung had no real effect on parent biomass and number of parent individuals, and there was a real difference in offspring biomass and number of Lumbricus rubellus offspring in the initial study.
