Pemanfaatan Tongkol Jagung Sebagai Bahan Dasar Pembuatan Super Absorben Polymer
Abstract
Corncob, the remnant of a corn plant, is considered as reusable waste for
its richness in fibers that can help with water absorption, such as cellulose,
hemicellulose and lignin. At this point, superabsorbent polymer has been
developed to absorb water, and has possessed the absorptive capacity up to
hundreds times more than polymer mass. In agriculture, improving physical
properties of the soil for the better productivity is something that has been done
for a long time.
This research was conducted to examine what corncob contains so it can be
used as the basic component of the SAP making. In this study, the test methods
used are the cellulose test for discovering the cellulose content in corncob, and
the swelling test in order to determine the water percentage that can be absorbed
by SAP. Also being conducted is the observations to calculate how much time is
needed for SAP to shrink.
This research finds that corncob contains 60% of cellulose, which is a
sufficient number. Moreover, to make SAP, a cellulose component is required.
From the swelling test, it is determined that the percentage of SAP water
absorption is 1255%, and based on the process observations, the SAP shrinkage
needs 10 days to return to the normal weight.
