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

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.
The Effectiveness of Three Types of Tissue Culture Media on the Growth and Jasmone Content of Jasmine (Jasminum sambac) Callus: Efektivitas Tiga Jenis Media Kultur Jaringan Terhadap Pertumbuhan dan Kandungan Melati Kalus Melati (Jasminum sambac) Aritonang, Erfan Andrianto; Widya, Surya Ari

Abstract

Jasmine is a herbaceous plant that has its own charm, especially its fragrant aroma, so the demand for jasmine extract is very popular. With the large industrial demand as a raw material, it is necessary to study the growth, development and content of jasmone in jasmine callus on 3 types of media in order to increase the content and efficiency of media use. This research aims to determine the growth, development and jasmone content in Jasminum sambac jasmine callus grown on MS (Murashige and Skoog), VW (vacin and Went), and NT (Nagata and Takebe) media in vitro. This research was carried out using a Completely Randomized Design (CRD), repeated 5 times and in each replication there were 3 samples. The treatment is as follows: 1. MS media (M1); 2. VW Media (M2); 3. Media NT(M3). Using parameters for observing the quantity and quality of callus by scoring once a week and analyzing secondary metabolites. From the results of observing the quantity, quality and analysis of secondary metabolites with modified treatment on MS, VW and NT media, it can be concluded that the quantity of callus is not significantly different, but the quantity of callus on NT (Nagata and Takebe) M3 media tended to be better than MS (Murashige and Skoog) M1 and VW (Vacin and Went) M2 media, while the results of callus quality from all media tended to be compact and the results of secondary metabolite content in the media treatment NT (Nagata and Takebe) M3 produced better jasmone content (1.22%) compared to MS (Murashige and Skoog) M1 and VW (Vacin and Went) M2 media.

Abstract

The study aims to compare various information discussions about LOF viewed from various needs so that complete information is presented, making it easier for practitioners to find information about LOF so that they can practice in many alternative choices, providing an overview of the variation and diversity of problems related to LOF including sources of raw materials, effects of LOF treatment on plants, application techniques and others. Information about LOF is taken from research papers or ideas published in reputable international journals to national journals that have not been accredited. Liquid organic fertilizer can be made from various types of waste such as rice washing water, banana stems, food scraps, market waste, kitchen waste, fish offal, water hyacinth, weed leaves, solid/liquid animal waste (buffalo, cow, goat, rabbit, chicken), shrimp, seaweed, sprouts, catfish waste and coffee grounds. LOF application by spraying or pouring on plants, dilution with a concentration of 1 ml - 60 ml per liter of solution. LOF application has a very real effect to no real effect on plant growth and yield. Liquid organic fertilizer as one of the organic waste processing products to support increased agricultural production.
