ANALISIS KANDUNGAN KIMIA DAN SIFAT SERAT TANAMAN PURUN TIKUS (Eleocharis dulcis) ASAL KALIMANTAN SELATAN

Abstract

Purun tikus (Eleocharis dulcis) is an aquatic plant which grows in great
amount in swamp lands in South Kalimantan. This research is conducted to find
out chemical content and fiber properties to know the potential utilization of this
plants. The results showed that the water content of purun tikus plant is 92,68%,
extractive in alcohol-benzena content is 9,53%, lignin content is 26.4%; and the
cellulose content is 32,62%. The study of purun tikus fiber anatomy have been
completed with the results of the fiber diameter is equal to 5.89 μm; lumen
diameter is 2.68 μm, cell wall thickness is 1.61 μm and fiber length is 1.68 mm.
The value of the derivative dimension of purun tikus fiber obtained as follows:
runkel ratio is 1.2; mulstep number is 38.4 (%), power loom is 285.45, value of
flexibility is 0.45 and stiffness coefficient is 0.27. All results suggested that purun
tikus plants offers potential for cellulose and fiber resources.
