Abstract
Mimba or Azadirachta indica A juss, is a kind of plant that can be utilized as material of nature pesticide
and medicine. Parts of the mimba plant that often the utilized are its seed and leaf. This research aims to
find out the influence of extraction temperature and ratio of solvent to feef to the yield. The obtained
concentration of the mimba leaf extract can be used to determine the mass transfer coefficient. The
extraction process was performed using three neck flask with a mixer and ethanol 96% as a solvent. At
the beginning, the mimba leafs with -30+80 mesh was feed into the flask that containing amount of
solvent and an overhead stirrer with 350 rpm. Ratio of solvent to feef was varied as well as temperature.
To study the influence of temperature, time for extraction process was limited of one hour. However, to
observe the influence of ratio of solvent to feef, the process was running untill the mimba the mimba leaf
extract was constant. Within the process, periodically the extract was drawn out. Finally, the extract was
observed using a spectrometer. Based on the results, the extraction of mimba leaf at 70o
C on the ratio of
solvent to mimba leaf of 35 ml : 1 gram will result mimba leaf extracted of 7,41% and mass transfer
coefficient of 4,27.10-5
(g extract/minute.mm2
).
