Abstract

Planting glutinous corn on peatland must be treated using ameliorant ingredients of manure fermented with EM4 and growth regulators. Ameliorated peatland can accelerate the supply of organic and mineral compounds which is easily absorbed by plants so that production can be optimized.  This study aims to see the response of ameliorant ingredients and growth regulators on the growth and production of glutinous corn of Arumba (Zea mays L. Ceratina) variety on peatland. This study used a randomized block design (RAK) in factorial consisting of two factors, and three replications.  The first factor was the ameliorant material (A), namely A0 = without ameliorant (control), A1 = cow manure fermented with EM4, A2 = chicken manure fermented with EM4, A3 = goat manure fermented with EM4 and he second factor is the type of Growth Regulatory Substance (ZPT), namely Z0 = without ZPT (control), Z1 = Superior Plant Hormone Growth Regulator (Ghost), Z2 = Harmonic Growth Regulatory Substance, Z3 = Atonic Growth Regulator Substance. The variables observed included plant height (cm), stem diameter (cm), weight of wet bean (g), weight of ear (g), length of ear (cm) diameter of ear (cm).  The results showed that the ameliorant material from chicken manure fermented with EM4 and the use of superior plant hormone growth regulators (phantoms) provide optimal growth and production of glutinous corn because it corresponds to the description of glutinous corn of the Arumba variety, and is the best treatment.

Abstract

Enterotoxigenic Escherichia coli (ETEC) is one of the most common bacteria that cause a large number of diarrhea in infants, children and adults living in developing countries. Potential activity of Ciherang rice’s (Oryza sativa L. var. Ci-herang) leaves’ extract as antibacterial agent against the ETEC was investigated in this research. The secondary metabolite was extracted, its antibacterial activity, and its minimum inhibitory concentration (MIC) against the ETEC were determined. This study indicated the leaf extract of Ciherang rice in the ethanol fraction contained tannins, saponins, flavonoids, alkaloids, and terpenoids. It showed strong antibacterial activity against ETEC (at concentration of 100%); the extract activity test had diameter of inhibition zone around 11.12 mm with MIC value of 11.12 mm. This study suggested the ethanol leaf extract at various concentrations showed significant effect (p<0.05) toward the diameter of the inhibition zone. The Ethanol leaves extract of Ciherang rice at 100% of concentration has a MIC value of 11.37 mm.
