Abstract

This research aims to determine the effect of from kepok banana peel extract (Musa acuminata balbisiana Colla) and BAP and their interaction on the growth of red potato plantlets (Solanum tuberosum L.) in vitro. This research was conducted in September-October 2023 at the G10 Agrotech Medan Plant Tissue Culture Laboratory Jl. Sei Bahorok No. 47 F Medan Baru. This research used a factorial Completely Randomized Design (CRD) with two factors. The first factor is the concentration of Kepok banana peel extract in 3 levels, namely (0, 25 and 50 g/L) and the second factor is BAP which consists of 4 levels, namely (0, 0.5, 1 and 1.5 mg/L). 12 treatment combinations were obtained and each treatment was repeated 3 times to obtain 36 experimental units. The research parameters were plantlet height, number of shoots, number of leaves and number of roots analyzed using Analysis of Variance (ANOVA) and if they were significantly different, further tests would be carried out using the Duncan Multiple Range Test (DMRT) at the 5% level. The results showed that the treatment of kepok banana peel extract and BAP had a significant effect on plantlet height, number of shoots, number of leaves and number of roots. The highest average plantlet height was produced by banana peel extract 50gr/L (7.60 cm), BAP 1mg/L (6.70 cm). The highest number of shoots was produced by banana peel extract 50gr/L (6.33 shoots), BAP 1.5 mg/L (6.33 shoots). The highest number of leaves was produced by sweet corn extract 25 gr/L, namely (10.00 leaves), BAP 0.5 mg/L as much as (8.00 leaves). The highest number of roots was produced by the 50gr/L sweet corn extract treatment, namely (12.00 roots), the highest number of roots was produced by BAP 1 mg/L, namely (7.33 roots). The highest average plantlet height, number of shoots and leaves were produced by the A2B1 treatment interaction, namely 7.40 cm plantlet height, 6.33 shoots and 16.33 leaves. The highest number of roots was produced by the A2B2 treatment interaction, namely 8.67 roots.  This is an open-access article under the CC-BY-SA license

Abstract

Makrozoobenthos plays a crucial role in ecosystems as producers, primary consumers, and decomposers or detritus that can degrade organic compounds into inorganic ones. As primary consumers, the role of makrozoobenthos is vital for the survival of wildlife, especially various species of shorebirds commonly found in coastal areas and fish-shrimp pond areas. The aims of this research is determining the abundance of makrozoobenthos (ind/m3) and ecological index at the pond in Ulee Matang Village. The diversity of macrozoobenthos species in the area consists of 12 species of three phylum and six classes. The abundance of macrozoobenthos on two type of pond (fish and shrimp) are ranging from 892 ind/m3 to 1400 ind/m3. The Arthropoda phylum, abundant in the research area, notably featured the Water Flea Daphnia sp. that serving as a primary food source for fish and shrimp prior to the introduction of fish and shrimp seeds. This suggests a significant role of arthropods in the food chain, supporting not only fish and shrimp but also macrozoobenthos and shorebirds.

Abstract

The potential of plants as an alternative medicine is a great gift. This potential can be explored through various preliminary tests. One of the preliminary tests is to analyze the content of secondary metabolite compounds using GC-MS. One of the plants known to have potential is Biden Pilosa L. The results of the GC-MS analysis showed that there were 9 compounds identified as having antimicrobial properties. This was discovered after analyzing the compound content and continuing with a literature review. The conclusion obtained was that there were 9 compounds in the ethanol extract of Biden Pilosa L leaves that functioned as antimicrobials.
