| Summary: | Electrospinning is a simple and attractive approach to the manufacture or
spinning of fibers with high porosity and fiber diameter at the nanometer scale so
that it is well used in research on filter development. The filter solutions that can
be used are so diverse that a variety of nanofiber filters are produced and can be
used for various types of filtration. In this study, the effect of thickness and
orientation distribution of the nanofiber filter membrane will be examined as an
air filter. To achieve this goal, the spinning time and electrospinning speed of the
drum collector are used using voltage variations of 8.7, 9.5, and 10.8 Volts to
produce 234, 198, 162, and 150 rpm respectively. Filters produced from the
electrospinning technique will go through several tests. Tests carried out are by
measuring thickness, pressure drop test, and efficiency test. The results shown in
this study will be obtained from the physical discussion of the form of comparison
of morphological parameters, fiber thickness distribution, efficiency and
coefficient of variation. The coefficient of variation representing the
morphological distribution of the rotational rates with different rpm 168, 192 and
234 rpm shows values of 0.586, 0.395, 0.343, respectively, even with the same
spinning time parameters.
