Pengaruh Perlakuan Alkali terhadap Kekuatan Tarik Serat Tandan Kosong Kelapa Sawit untuk Digunakan pada Komposit Serat Tkks
Abstract: Empty Palm bunches
(TKKS) is one of the solid waste generated by industrial palm oil plantations
which contain lots of fiber and is one of the natural fiber source that the
availability of abundant in Indonesia, especially in the province of Lampung.
TKKS fiber can be used as an alternative amplifier to composite materials. This
research was conducted to determine the influence of the chemical composition
of TKKS fiber and know the tensile strength from TKKS fiber by doing a tensile
test. Alkaline treatment NaOH 5% given to fiber to separate lignin and
contaminants that contained in fiber so that it can increase the tensile
strength fibers. TKKS fiber is obtained processing palm oil factory by the
process of boiling oil palm fresh fruit bunches with a pressure of 2.5 until
3atm at temperature 1300C during 50 – 60 minutes. TKKS already parsed and then
selected and measured with a length of 6 cm and a diameter of 0.2 mm. And then
given an alkaline NaOH 5%. In this research on the treatment of alkaline NaOH
5% provided that treatment during 0 hours (without treatment), 2 hour, 4 hour,
6 hour. Results from the study found that fiber tensile strength affected by
the chemical composition on the fiber, the higher the tensile strength of the
cellulose content is increasingly high. Tensile strength in fiber with alkali
treatment 2 hours of 0,03528 Mpa, 0,3996% strain, 0,088288 MPa elasticity modulus, if compared
with fiber without alkali treatment of
0,018946 MPa tensile strength, 0,2056% strain, 0,092149 MPa elasticity modulus.
This is due to the levels of cellulose fibers with alkali treatment 2 hours
increased by 58,2808%, if compared with
fiber without alkali treatment by 13,2848%.
