Abstract

The obstacles faced in increasing and stabilizing the production of pakcoy Brassica rapa L. one of them is due to pest attacks. The main pests that attack pakcoy plants are Plutella xylostella L., C. pavonana, earthworms (Agrotis ipsilon), and grayworm (Spodoptera litura). The use of pesticides can provide the only form of crop protection available Developing countries from some pesticides that have been banned from use in the European Union (EU), as they have recognized the harmful properties of such pesticides. Vegetable pesticides are effective against various destructive pests and diseases. Broadly speaking, vegetable pesticide raw materials are easy to obtain, cheap, easily accessible, quickly decompose, and have little toxicity to receiving agents. Simplisia vegetable pesticide product is a pesticide product based on soursop leaves, lemongrass, and papaya leaves. All three ingredients contain chemical compounds or extractive substances. This study used vegetable pesticide simplicia products with several concentrations to suppress the attack of pakcoy leaf-destroying pests. The research took place in the experimental garden was carried out for 4 weeks from the seeding period to harvest. Research is carried out by experimental methods. The results of this study show that vegetable pesticide simplicia is able to suppress the attack of pakcoy leaf pests with a very significant concentration found in the P2 treatment, which is 40grams per liter of water
Growth Test of Pakchoy (Brassica rapa L) Against Abiotic Stress from the Heavy Metal Pb: Uji Pertumbuhan Tanaman Pakcoy (Brassica rapa L) Terhadap Cekaman Abiotik Logam Berat Pb Helios, Sergio; Inti, Ristani Widya; Larissa, Damasa Ines; Widya, Surya Ari

Abstract

The pakchoy plant also faces various challenges in its growth environment, including exposure to abiotic stressors. Heavy metals, such as lead (Pb), are environmental contaminants that can have significant negative impacts on plants. Therefore, this research aims to investigate the resilience of pakchoy plants (Brassica rapa L.) to concentrations of abiotic stress from the heavy metal Pb. This is achieved through a series of experiments to understand the effects of exposure to the heavy metal Pb on growth and to analyze the accumulation of heavy metals in pakchoy plants. Pakchoy plants (Brassica rapa L.) can grow under conditions of heavy metal Pb stress; however, as the concentration of Pb increases, the growth of the plants becomes progressively slower. This is evidenced by a reduction in height, leaf number, plant biomass, and the accumulation of heavy metal Pb in the plant tissues. Consequently, these plants are categorized as phytoremediators due to their ability to accumulate heavy metal Pb.
