PENGARUH ALOE VERA PADA TRANSMITANSI ULTRASONIK GEL KARBOMER 940
Abstract: On examination
using USG ( ultrasonography), gel carbomer
940 applied on body surface has role as acoustic coupling agent between USG
probe and body surface. The function of this gel is to transmit ultrasonics wave from probe to body without
resisted by the air. Gel carbomer 940 is a non biodegradable matter. For
decreasing the content of non biodegradable part of carbomer 940, in this
research, the extract of aloe vera was added into gel carbomer 940. To know the
efficiency of ultrasonics energy tramsmitted to the body, transmitansi
coefficient measurement is required.. Transmitansi coefficient can be
calculated from ultrasonics velocity value in the gel. The velocity measurement
use transmit time method with equipment the ultrasonics thickness gauge AR860
connected to osciloscope. Examanation of the coefficient was carried out
in first and 12 th week. The results
indicated the acoustic impedance and the transmitansi coefficient decreased by
adding of aloevera content. However at 12 th week the influence of aloe vera relatively
did not give effect to the gel carbomer transmittance.
