Abstract

Nut grass is defined as a weed that can reduce agricultural yields because it contains allelopathic compounds which have a negative impact on the sprouts and initial growth rate of spinach weed. The written research aims to find out whether allelopathic extracts from sedge grass can influence the germination and initial growth of thorn spinach weed. The research was carried out using a Completely Randomized Design (CRD) consisting of four treatments, each repeated six times. The treatment is defined as: A0 as a control with water, A1 with 50 grams of tekhi per liter of water, A2 with 100 grams of tekhi per liter of water, and A3 with 150 grams of tekhi per liter of water. The results of the study showed that in treatment A3 (150g tekhi/L water) on the last day, the allelopathic extract of tekhi caused abnormalities in 75.17% of spinach spinach seed sprouts. In polybags, A3 treatment (150g tekhi/L water) on the last day reduced the growth rate of the number of seedlings from 25 plants to only 1 plant (96%), with a seedling height of 1 cm and a number of leaves of 3.67 pieces. The higher the treatment dose, the greater the effect in suppressing germination and initial growth of thorn spinach weed.

Abstract

In the form of natural aerosol formulations and preparations, butterfly pea flower kombucha in the form of waste can be utilized as a pharmaceutical biotechnology product to inhibit the growth of pathogenic fungi that cause disease or infection in horticultural commodity plants. Horticultural commodity plants are plant commodities that have the potential to be developed as food flavorings, traditional medicines, and spices, especially in the shallot species Allium cepa L. One of the obstacles to the growth and development of shallot plants is being hampered by attacks by pathogenic fungi from the species Fusarium fujikuroi, Alternaria sp, and Colletotrichum gloeosporioides. A safe and environmentally friendly solution to prevent the growth of these three pathogenic fungi is to utilize the fermentation waste of butterfly pea flower kombucha as a pharmaceutical biotechnology product in the form of natural spray formulations and preparations with concentrations of 20%, 30%, and 40%. Based on the one-way ANOVA test with each P value <0.05, supported by post hoc analysis. Specifically, the 40% formula differs significantly from the 20% and 30% formulas as a pharmaceutical biotechnology product in its ability to inhibit the growth of the three pathogenic fungi in shallot plants, and is the most optimal formula.

Abstract

Rice (Oryza sativa L.) is a staple crop for all Indonesian people. Rice production in Indonesia in 2019 experienced a decline in production. Plant disease attacks are a factor that influences the decline in rice production. Bacterial leaf blight is an important disease in rice plants that can cause yield losses of up to 50%. Characterization of disease-causing bacteria needs to be carried out to develop appropriate, effective and efficient control in suppressing the development of bacterial leaf blight. The aim of this research was to characterize the morphological and physiological characteristics of the bacteria that cause bacterial leaf blight. The method used in this research included the isolation of bacteria that cause bacterial leaf blight disease carried out on rice plantations in Pulungan Village, Sedati, Sidoarjo. Identification is carried out through macroscopic and microscopic observations, analysis of physiological properties through the gram staining test, fermentative oxidative test, yellow colony test on YDC media, urease test, hypersensitivity test, and pathogenicity test. The results of the research show that the bacteria that cause bacterial leaf blight have the morphological characteristics of being yellow, round and shiny. The physiological characteristics of the bacterial isolate are gram-negative bacteria, are oxidative, yellow in YDC media, and react negatively in the urease test.
