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

Bioethanol is an energy source obtained through fermentation. In bioethanol production, Persea americana seeds are used as a fermentation medium because they contain lots of carbohydrates. This research aims to determine the effect of additional nutrients (NPK and urea fertilizer) required by Saccharomyces cerevisiae by varying the nutritional variables in the form of NPK and urea fertilizer. The process of making bioethanol goes through stages: making Persea americana seed flour, hydrolysis process using 6% HCl, then fermentation process, and distillation process. This research was carried out with the addition of Nutrients in the form of NPK and Urea Fertilizer with 5 treatments, namely: A) 100% yeast (no addition of Nutrients); B) 100% NPK (4 g); C) 100% Urea Fertilizer (4 g); D) 50% NPK and 50% Urea Fertilizer (4 g NPK and 4 g Urea Fertilizer); and E) 75% NPK and 25% Urea Fertilizer (3 g NPK and 1 g Urea Fertilizer), and varying the length of fermentation time to 13, 19, and 25 days. Success parameters are assessed through the bioethanol yield produced by each treatment. The research results showed that the highest bioethanol (29.7 ± 0.47%) was composition E (NPK 75% and Urea Fertilizer 25%) with a fermentation time of 25 days.
