“Formulasi Dan Karakterisasi Hidrogel Ekstrak Daun Dadap Serep (Erythrina folium) Dalam Bentuk Plester Sebagai Penurun Demam”.

Fever is a condition where the body temperature is more than 37.5oC, fever
can also be an early clinical manifestation of a certain infection. Efforts to
overcome the fever begins with self-medication that is with sympathetic
treatment. Dadap plant is a plant that examines many properties as traditional
medicine, but this plant can only be found in certain regions. Efforts should be
made to create new innovations in preparations that can provide convenience to
the community by making hydrogel preparations with natural ingredients namely
leaf dadap serep which is efficacious in treating fever.
The population in this study was the Dadap leaf extract hydrogel. The
spare dadap leaf was taken in Tulung Village, Sampung District, Ponorogo
Regency. This research was carried out by making three hydrogel formulas of
Dadap leaf extract spare with a composition of every 30 g of preparations
containing Dadap leaf extract F1 for 2.5 g; F2 for 5 g, and F3 for 10 g. From the
three formulas, the physical properties of the hydrogel were analyzed to see the
characterization of the hydrogel which included organoleptic test, pH test,
viscosity test, homogeneity test and temperature drop test in mice test animals
The results of the three hydrogel formula extracts of Dadap's leaf extracts
are F1, F2 and F3 have the same characterization, they are semi-solid shape,
characteristic odor and green color, hydrogel pH is 6.0-6.5, viscosity 170,000-
236,000 cP and homogeneous. In the temperature reduction test with mice test
animals effective on the hydrogel formula Dadap leaf extract with a composition
of every 30 g of preparations containing leaves extracts of Dadap spare 5 g and
10 g
