Abstract

Hydroponics, a farming technique using nutrient-enriched water, has been widely practiced due to its suitability for limited agricultural land. One of the key factors affecting hydroponic efficiency is the nutrient blend, with AB Mix and liquid organic fertilizer playing a crucial role. This study aims to evaluate the potential of nanotechnology-based nutrient solution in hydroponic to enhance nutrient absorption and improve plant growth in different vegetable species. Five vegetable species, which include red lettuce, red spinach, green spinach, pakcoy, and kailan, were selected to assess the interaction between nutrient composition and vegetable species. A study with factorial design was conducted using a randomized complete block design (RCBD). The primary factor was the fertilizer composition and the secondary factor was the type of vegetable. The treatments consisted of Control (Well water + AB Mix), P1 (Nanotechnology water + 100% AB Mix), P2 (Nanotechnology water + 25% nanotechnology liquid organic fertilizer + 75% AB Mix), P3 (Nanotechnology water + 50% nanotechnology liquid organic fertilizer + 50% AB Mix), P4 (Nanotechnology water + 75% nanotechnology liquid organic fertilizer + 25% AB Mix), and P5 (Nanotechnology water + 100% nanotechnology liquid organic fertilizer). Growth parameters measured included plant height, fresh weight, dry weight, number of leaves, and leaf area. Data were evaluated using a two-way ANOVA to assess the effects of fertilizer composition and vegetable type, followed by a 5% DMRT test for mean comparison. The findings indicated that the use of liquid organic fertilizer technology influenced plant growth. The most optimal average growth was recorded in the P2 treatment (a combination of nanotechnology water, 25% nanotechnology liquid organic fertilizer, and 75% AB Mix), while the least favorable result was observed in P5 (nanotechnology water combined with 100% nanotechnology liquid organic fertilizer).

Abstract

Greening along roads can be an alternative solution to overcome air pollution in urban areas. Direct contact of plants with pollutant particles in the air will affect the condition of plants, especially on leaves. Knowledge of morphological characteristics and stomata on leaves that have the potential to absorb pollutants is the basis for understanding plant responses to environmental changes. This research is descriptive research conducted in September-December 2021 with leaf samples taken in the area of ​​PT Semen Padang, Padang State University, and Andalas University forests. Data were analyzed by t test level of 5%. The results showed that the morphological characteristics of trembesi leaves in the PT Semen Padang and Padang State University areas had significant differences in the aspects of the number of leaflets, leaf length, leaf width, not significantly different in the length of the mother petiole and the number of leaf branch bones and the characteristics of the stomata did not show any difference which is evident from the aspect of stomata length and stomata density. The morphological characteristics of trembesi leaves in the Padang State University and Andalas University forests showed significant differences in the length of the mother petiole, the number of leaflets, and the number of leaf veins, there was no significant difference in leaf length and leaf width and showed a significant difference in the aspect of stomata length, but did not show a significant difference in terms of stomata density. Morphological characteristics of trembesi leaves in the PT Semen Padang area and Andalas University forest showed significant differences in the length of the mother petiole, number of leaflets, leaf length, leaf width, and number of leaf veins and did not show significant differences in terms of stomata length and stomata density.

Abstract

Sauerkraut is a typical German food made from thinly sliced cabbage. Sauerkraut is a fermeted product that can give a distinctive taste. Sugar is an ingredient that can be added in, that sugar can trigger the growth of lactic acid bacteria. Indonesian people like food with a spicy sensation from chilies, chillies here contain vitamin C which functions as an antioxidant that is good for the body and is able to increase endurance. This study aims to calculate the total lactic acid bacteria contained in sauerkraut with the addition of chilies and sugar. Dilution of 1 ml sample into 9 ml physiological NaCl solution from 10 -1 to 10 -8 dilutions was carried out, then inoculated into MRS Agar using the pour plate method. Incubated in room temperature for 48 hours. The growing colonies of lactic acid bacteria were then observed based on colony morphology and counting the total growing lactic acid bacteria. The results of the research can be concluded that there was an increase in the number of lactic acid bacteria in sauerkraut with the addition of chili and 10% granulated sugar with a bacterial density average is 88.667 x 108 CFU/mL.
