KADAL IRAN (ETHANOL CONTENT NIRA SIWALAN (Borassus flabellifer)) WITH GC-MS (GAS CHROMATOGRAPHY MASS SPECTROMETRY) ANALYSIS

Abstract

There are many siwalan saplings among the people who utilize various kinds of fruit,
leaves, nira siwalan. However, many people like the fruit and the water. In this case, legen
lontar or other names nira siwalan can produce ethanol from siwalan flowers. So that, from
many people using nira only as a drink and so far some people produce nira on a small scale.
Nira is a liquid that contains certain sugar levels, namely sucrose, glucose, fructose and
carbohydrates, which have an average acidity level of 6-7 and smell nice. This study aims to
determine the amount of ethanol content contained in nira siwalan and determine the effect of
storage time on ethanol levels in nira siwalan. Samples of nira siwalan both original and
bulk were fermented for 3 days, 6 days, and 9 days and then distilled at a temperature of
78.37 ° C. Determination of ethanol content in the distillate results was carried out using
GCMS (Gas Chromatography Mass Spectrometry). The results of this study are the original
ethanol content of nira siwalan at storage of 3.6.9 consecutive days, namely 0.27%, 0.91%,
and 1.02%. While the results of the bulk ethanol juice of the siwalan level at storage of 3,6.9
days were obtained ethanol levels respectively ie 32.05%, 39.99% and 44.42%. From this
study it can be concluded that the ethanol content in bulk nira siwalan is more than the
original nira siwalan.
