Abstract

Lettuce (Lactuca sativa L.) is a horticultural crop with high nutritional content and economic value, offering good prospects for cultivation. It is a seasonal plant that is easy to grow on various types of land and has a broad market demand. This study aimed to determine the production response of lettuce to different types and concentrations of ecoenzyme-based liquid organic fertilizer (POC). The research used a factorial Completely Randomized Design (CRD) with two factors and three replications. The first factor was the type of POC with five treatments: P0 = AB Mix (control), P1 = Pure Ecoenzyme (EE), P2 = EE + eggshell + pineapple, P3 = EE + moringa + insulin plant leaves, P4 = EE + guava + sweet potato + long bean leaves, and P5 = EE + water spinach + young corn. The second factor was the concentration of ecoenzyme (E0 = 0%, E1 = 25%, E2 = 50%). Observed parameters included plant height, number of leaves, fresh weight per plant, stem diameter, plant weight per plot, and root length. The results indicated that P5 (EE + water spinach + young corn) performed well and ranked second after the AB Mix across most parameters. This suggests that diverse organic ingredients in liquid fertilizers can support optimal lettuce growth, making them a promising alternative to chemical fertilizers.

Abstract

Shallots (Allium ascalonicum L.) are horticultural plants that can be used as raw materials for the food seasoning and pharmaceutical industries. People highly appreciate their unique flavor and aroma. In addition, shallots contain minerals, potassium, phosphorus, and vitamins B and C. This research was conducted to determine the effect of biochar and ecoenzymatic treatments on the growth response and production of shallots (Allium ascalonicum L.). The research method used a Factorial Randomized Block Design (RAK) with two treatment factors. The first factor was biochar application with 4 levels: A0 = control, A1 = 650 grams/plot, A2 = 750 grams/plot, A3 = 850 grams/plot. The second factor was ecoenzymatic application with 3 levels: B = control, B1 = 500 ml/plot, B2 = 1000 ml/plot. This resulted in 12 treatment combinations and 3 replications. The observed parameters were plant height (cm), number of leaves (sheets), number of offsets per plot (bulbs), fresh bulb weight per plot (g), dry bulb weight per sample (g), and dry bulb weight per plot (g). The results showed that biochar and ecoenzymatic treatments had a significant effect on plant height (cm), number of leaves (sheets), number of offsets per plot (bulbs), and dry bulb weight per sample (g). However, these treatments did not significantly affect the fresh bulb weight per plot and dry bulb weight per plot (g).

Abstract

The utilization of organic fertilizers can be a solution to reduce dependence on inorganic fertilizers and also contribute to improving the surrounding environmental conditions. This study aims to evaluate the effect of applying fruit waste POC and goat manure fertilizer on the growth of purple eggplant (Solanum melongena L). The experimental design used a randomized block design consisting of two factors. The first factor is the dose of goat manure fertilizer, which includes: K0 (0 kg/plot), K1 (2 kg/plot), K2 (4 kg/plot) dan K3 (6 kg/plot). The second factor is the concentration of fruit waste POC, which includes : B0 (0 ml/L.air/plot), B1 (100 ml/L.air/plot), B2 (200 ml/L.air/plot) dan B3 (300 ml/L.air/plot). The parameters observed in this study include plant height, stem diameter, number of productive branches, number of fruits per plant, number of fruits per plot, weight of fruits per plant, and weight of fruits per plot. The analysis of variance shows that the application of goat manure fertilizer and fruit waste POC did not have a significant effect on plant height, stem diameter, and the number of productive branches. However, there was a highly significant effect on the number of fruits per plant, the number of fruits per plot, the weight of fruits per plant, and the weight of fruits per plot. The interaction between the two treatments did not affect all observed parameters. Keywords: purple eggplant, fruit waste poc, goat manure fertilizer

Abstract

This research aims to determine the effectiveness of using varying concentrations of ecoenzymes in cultivating white oyster mushrooms (Pleurotus ostreatus), and to determine the effectiveness of using varying concentrations of brown sugar in cultivating white oyster mushrooms. White oyster mushrooms require nutritional supplements during their growth. Additional nutrients are obtained by using water-soluble ecoenzymes and fertilizing oyster mushroom substrate. Ecoenzyme nutrients and brown sugar can increase the yield and growth of oyster mushrooms at harvest. This study used a completely randomized factorial design (CRD) with 2 factors, 16 treatments, 3 replications, and 48 logs. Factor 1 of brown sugar is symbolized by G0 = 0%/baglog, G1 = 40%/baglog, G2 = 80%/baglog, G3 = 120%/baglog. Factor 2 ecoenzyme with symbols E0 = 0%/baglog, E1 = 20%/baglog, E2 = 40%/baglog, E3 = 60%/baglog. The data obtained were analyzed using ANOVA, and continued with the Duncan distance test. The results showed that the highest mycelium growth was in G0, namely 28.83 cm, the highest mushroom stalk height was E0, namely 3.93 cm, the largest cap diameter was in E1, namely 7.68 cm, the highest number of tillers was E3, namely 7 .50 tillers. The highest wet weight is in G3, namely 109.00 g. The height of mushroom mycelium growth, number of branches, cap thickness, mushroom body height and cap diameter in the interaction of brown sugar intake and ecoenzymes in white oyster mushrooms gave results that were not significantly different, but the wet weight results were very significantly different. The results differ significantly.Keywords: ecoenzymes, brown sugar, oyster mushrooms INTISARIPenelitian ini bertujuan untuk mengetahui efektivitas penggunaan konsentrasi ekoenzim yang bervariasi pada budidaya jamur tiram putih (Pleurotus ostreatus), dan mengetahui efektivitas penggunaan konsentrasi gula merah bervariasi pada budidaya jamur tiram putih.

Abstract

This study aimed to evaluate the antifungal activity of eco-enzyme (EE) derived from various horticultural organic wastes against Candida albicans. Two formulations were prepared: Bioz1 (pineapple peel, orange, papaya, starfruit, kuini, and mango) and Bioz2 (pineapple, orange, banana corm, noni, and kuini). Both were fermented for 100 days. The antifungal activity was tested in vitro using the disc diffusion method at concentrations of 1:0, 1:10, 1:50, and 1:100 (EE: distilled water). Results indicated that Bioz1 at 1:50 exhibited the highest inhibition zone (7.38 mm, medium category), while Bioz2 at 1:0 showed the strongest activity (8.16 mm, medium category). Dilution at 1:10 in Bioz2 was the most effective concentration for inhibiting fungal growth. These findings highlight the potential use of eco-enzyme as an environmentally friendly natural disinfectant against pathogenic fungi
