Pengaruh Konsentrasi NaOH dan Waktu Proses Kostikasi Terhadap Pengurangan Massa Serat Daun Nanas
Keywords:
Kostikasi, Serat Daun Nanas, NaOH, Waktu Proses, Pengurangan MassaAbstract
This study aims to explore the effect of NaOH concentration and costication process time on the reduction
of pineapple leaf fiber mass as an alternative environmentally friendly textile raw material. The costication
process is carried out using NaOH solution at various concentrations and times to decompose pectin and
hemicellulose compounds that bind the fiber. The results showed that increasing NaOH concentration and
costication process time had a significant effect on fiber mass reduction. Higher NaOH concentrations and
longer times reduced greater mass reduction, with the highest effectiveness recorded at a concentration of
7.5 g/L and a time of 600 seconds. The regression value showed a positive relationship between NaOH
concentration and its effectiveness in reducing fiber mass, as well as a negative relationship between
process time and its effectiveness. This study contributes to the development of pineapple leaf fiber as an
environmentally friendly textile raw material.
