ABSTRACT
Industrial waste of dried shrimp shells contains chitin which can be used as raw
material for chitosan synthesis. Along with the development of technology,
product with using chitosan continues to be developed by physically modifying
chitosan into nanochitosan so that it has a wider utilization than chitosan. This
study was aimed to synthesize nanocitosan using the ionic gelation method and
determine the effect of the acetic acid concentrations and sodium
tripolyphosphate concentrations on the characteristics of nanochitosan. The
procedure of nanochitosan synthesis by dissolved chitosan with acetic acid to
obtain 0.2% chitosan solution and stirred with a magnetic stirrer. NaTPP solution
with a chitosan volume ratio of NaTPP 5: 1 was added to the chitosan solution
and stirred for 1 hour at a speed of 1200 rpm. Furthermore, the nanochitosan was
characterized by using Particle Size Analyzer (PSA), zeta potential analyzer,
Scanning Electron Microscopy (SEM), and Fourier Transform Infrared (FTIR).
The acetic acid concentrations used were 0.5%, 1%, and 2% and NaTPP
concentrations used were 0.1%, 0.5%, and 1%. The increase in acetic acid
concentration (0.5%; 1% and 2%) with the constant of 0.5% NaTPP
concentration causes the polydispersity index decrease (1.451; 1.302 and 0.924.
2). The increase in acetic acid concentration (0.5% and 1%) with the constant of
0.1% NaTPP concentration causes the particle size decrease (2985.1 nm and
1827 nm), while the increase NaTPP concentration (0.1% and 0.5% ) with the
constant of 2% acetic acid concentration cause the particle size increase (2187
nm and 7788.7 nm).
Keywords: acetic acid, ionic gelation, nanochitosan, sodium tripolyphosphate
