Abstract

Tamarind (Tamarindus indica L.) can cure various diseases, one of which is diarrheal disease caused by Staphylococcus aureus bacteria. Tamarind fruit contains tannin compounds that have antibacterial abilities. This study aims to determine the inhibitory power of ethanol extract of young tamarind fruit against Staphylococcus aureus bacteria that cause diarrhea. The concentrations used in this study were 10%, 25%, 45%, 75% and 100%. The method used is the well diffusion method with 4 treatments and 4 repeats. The results showed that ethanol extracts of tamarind fruit young proved to be able to suppress the growth of Staphylococcus aureus bacteria with the highest inhibitory zone of 19.85 mm. This inhibitory power is a strong category in inhibiting bacterial growth.

Abstract

Pathogens are one of the obstacles in shallot cultivation. One of them is Fusarium sp. which resulted in damage reaching more than 50-75%. The aim of this study was to determine the virulence level of the fungus Fusrium.solani.f.sp.cepae that causes fusrium wilt in shallot plants. The method used is an experimental method with a completely randomized design (CRD) with two treatments: method of application and time of observation/measurement. The average incubation period of fusarium wilt disease on shallots without F.solani.f.sp.cepae treatment had no symptoms of attack, while those that were treated showed symptoms in a short time. The results showed that the pathogen F.solani.f.sp.cepae was able to attack plants with an average attack intensity of 4.22, meaning high attack intensity. Macroscopically identification of fungi that had grown on potato dextrose agar (PDA) medium was observed, observations starting from the shape of the mushroom colonies and the color of the underside of the mushroom colonies, while microscopically found insulating hyphae, forming branching and found macroconidia and microconidia spores.
