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.

Abstract

The group of enzymes known as proteases are widely used in industry. Proteases are chemicals that hydrolyze peptide bonds in proteins into oligopeptides and amino acids. When compared to other sources, such as proteases from animals and plants, proteases from bacteria are the most common. Proteolytic microbes are microorganisms equipped to degrade proteins, producing extracellular protease compounds. This study aims to determine the potential of laundry waste bioremediation agents in producing proteolytic bacteria. The research method is by experimenting directly starting with taking samples of laundry waste, then isolating it to get bacterial colonies, and purifying it so that later it will be easier to get proteolytic bacteria.

Abstract

Mycorrhiza is a type of biological fertilizer that can improve soil health, environmental protection, soil nutrient status and agricultural yields. The demand for tomatoes continues to increase every year along with population growth and in 2021. In order to meet the need for tomato consumption every year, various efforts are being made to continue to increase production through the use of minimal and environmentally friendly output such as the use of mycorrhiza biological fertilizer. This research aims to determine the effect of the use and dosage of mycorrhizal fertilizer on the growth of tomato plants (Lycopersicum esculentum Mill). This research was carried out on Jln Rela, Gg. Danau Toba, No. 16. starting from 10 September 2023 - 11 November 2023. Mycorrhizal fertilizer was given in 2 treatments, namely 5 gr and 10 gr with 2 repetitions each and control (no mycorrhizal fertilizer was given). Providing 10g of mycorrhizal biofertilizer/plant provides the best growth and results for tomato plants with the parameters of plant height and number of leaves.

Abstract

ABSTRACTThis study aims to determine the antibacterial activity of ethanol extract of Moringa oleifera L. leaves against the growth of Propionibacterium acnes bacteria in vitro and to determine the active compounds contained in the ethanol extract of Moringa oleifera L. leaves. This research is experimental and the method used is disc diffusion, namely by observing, measuring, calculating and analyzing the diameter of the growth inhibition zone of P. acnes which forms around the disc containing ethanol extract of Moringa leaves. The results of antibacterial activity show that the ethanol extract of Moringa oleifera L. leaves has antibacterial activity against the growth of Propionibacterium acnes bacteria and the active compounds contained in the ethanol extract of Moringa oleifera L. leaves which were tested using the phytochemical screening method, namely tannin and saponin compounds, and flavonoids.Keywords: Ethanol, Moringa leaves, antibacterial, Propionibacterium acnes.
