Abstract

In the hydroponic system, AB Mix nutrition is one of the standard nutrients used. In addition to the use of AB Mix, the use of ecoenzymes in hydroponic plants is also a big concern. This is what makes the authors interested in using ecoenzyme to help AB Mix for hydroponic growth and maintenance of pakcoy (Brassica rapa L.). This study aims to determine the effect of spraying ecoenzyme on the growth of pakcoy (Brassica rapa L.) which is cultivated hydroponically. This research will be carried out from December 2021 to February 2022 at the Plant Physiology Laboratory and the wire house of the Biology Department, FMIPA UNP. This study used a completely randomized design (CRD) with 5 treatments and 5 replications. Consists of: P1 (Control), P2 (1mL ecoenzyme + 1 L water), P3 (2mL ecoenzyme + 1 L water), P4 (3mL ecoenzyme + 1 L water), P5 (4mL ecoenzyme + 1 L water). The data obtained were analyzed by means of variance (ANOVA) with DMRT further test. The results of the study of spraying ecoenzyme on pakcoy (Brassica rapa L.) which were cultivated hydroponically had an effect on plant height growth with the highest average of 14.4 cm, and had no effect on leaf area.

Abstract

Spinach is one of the vegetables favored by the people of Indonesia and also has high nutritional value. Spinach can be cultivated conventionally or hydroponically. Hydroponics is one solution to the problem of limited land in farming that uses water as a nutrient medium that will be directly absorbed by plants to support plant growth. Hydroponics uses Ab-Mix nutrients. To get better results, ecoenzyme can be used as a support for plant fertilizers. This study aims to see the effect of spraying ecoenzyme on the number of spinach leaves. This study is an experimental study consisting of 5 treatments and 5 replications with a dilution of ecoenzyme solution, P1 (control), P2 (2mL ecoenzyme + 1L water), P3 (3mL ecoenzyme + 1L water), P4 (4mL ecoenzyme + 1L water), and P5 (5mL ecoenzyme + 1L water). The data obtained were analyzed by means of variance (ANOVA) with Duncan's New Multiple Range Test (DNMRT) further test. The results showed that spraying ecoenzyme on spinach plants had no effect on the number of plant leaves.

Abstract

Indonesia is a country that has the highest mega-biodiversity in the world. The number of species reported throughout the year increased for both amphibians and reptiles. In the territory of Indonesia, many types of anura are widely distributed and hindered by physical obstacles such as hills, mountains or the sea. One of the most widely distributed species is Pulchrana sundabarat which is found in southern Thailand, Peninsular Malaysia and Sumatra. However, previous researchers only analyzed specimens that only came from specimens that had been studied in Peninsular Malaysia. This study aims to determine the variation of morphological characters of Pulchrana Sundabarat in Sumatra, especially West Sumatra. This study used the Visual Encounter Survey (VES) method for sampling and the data obtained were analyzed descriptively and presented in tabular form. The results of this study found 11 individuals of Pulchrana Sundabarat from 4 different areas, including 9 males and 2 females. The distinguishing characteristics include body size, head shape and size, body pattern (dorsolateral line shape and color), color and distribution of spots on the dorsal, lateral and ventral sides.

Abstract

Litterfall is one of the important components that is taken into account in estimating primary productivity, especially to see its contribution to the estuarine ecosystem. The objective of the present study was to assess litterfall production rates of the Mangrove Forest in the Tourism Area of Pariaman City. Litterfall production in the study area was monitored from December 2021 - March 2022. The method used for litter collection is the litter-trap method. Sampling of mangrove litterfall were collected from 2 stations. Then, 6 litter-trap nets (Litter-trap) measuring 1x1 m2 were installed at each station which were randomly installed under the canopy of mangrove stands at a height of 1.5 m above ground level, so as to avoid the influence of tidal water. The litter production sample was then taken within 10 days for 6 times, the litter sample was then drying in air-circulation oven at 750C until constant weight was obtained. Then the litter mass was calculated within two months. The results of this study think that the average production in the Pariaman Mangrove Forest Tourism Park is 2.77 g/m2/day or 10.13 tons/ha/year with the order of the largest contributors being leaves > branches and twigs > generative organs.
