Abstract

This paper presents the SIRS epidemic model. Furthermore, the model is investigated the existence of the equilibrium point, and the global stability of the equilibrium point using the function Lyapunov.

Abstract

Some major countries, immigration is a significant factor in the epidemic of a disease. Because the disease follows a predictable pattern of illness, so it can be checked with a standard SIR Model. Kermack and McKendrik SIR models can be developed with the effect of vaccinations and immigrants. The model is built on the assumption, and then determines the vaccination of reproduction number (Rv), determines the equilibrium point on the model, determines the type of stability of the equilibrium point and makes a simulation with the parameter values.

Abstract

Purun Danau (Lepironia articulata (Retz.) Domin) has been shown to have antimalarial and antioxidant activity. This study aimed to standardize simplicia and extract of L. articulata by determining the value of its specific and non-specific parameters. A sampling of L. articulata rhizome was carried out in Guntung Manggis, Haur Gading, and Halat. The standardization method used was based on the Indonesian Herbal Pharmacopoeia and the General Standard Parameter of Extract. The organoleptic observations showed that L. articulata simplicia was reddish-brown in color, chelated taste, and had a specific odor. Microscopic observation showed parts of this plant: epidermis, cortex, endodermis, parenchyma, bundle vessels, and scalariform vessels. Ethanol-soluble extract content was 10.00-12.66%, water-soluble extract content 8.03-10.87%, drying shrinkage 7.10-7.33%, total ash content 2.03-2.52%, acid-insoluble ash 0.33-0.42%, Pb content 5.698-9.989 ppm, Cd content 0.300-0.500 ppm, Hg content 0.070-0.090 ppm. Ethanol extract of L. articulata rhizome contained alkaloids, flavonoids, tannins, glycosides, and saponins. The yield obtained was 8.05-11.23%, total ash content was 1.58-1.67%, acid-insoluble ash was 0.23-0.33%, and water content was 7.10-8.50%. Standardization of simplicia and ethanol extract of L. articulata rhizome has met the criteria.
