PEMBUATAN TALI SERAT BERBAHAN SERAT ALAMI KULIT DALAM BATANG POHON MELINJO (Gnetum gnemon)
ABSTRACT: Melinjo plant has a
very high quality of fiber that found in the inner bark of the stem that can be
made as a rope as a substitute to synthetic ropes that can decrease environmental
pollution. The research was aimed to make a fiber rope from the inner bark of
melinjo stem and to test the endurance of the rope toward a tensile test. The
research had been conducted at Agriculture Engineering Laboratory, College of
Agriculture, USU and tensile test was conducted at Research Laboratory, College
of Engineering, USU in March-July 2015 using spinners simple tool in making the
rope and tensile test to determine the strength of the rope toward burden.
Parameter measured were tensile stress, strain, elasticity, ropes deformation,
and malleability. The results showed that heterogeneous fiber caused different
rope diameter and affect the value of parameters measured. From the ropes test
it was found that average tensile stress was 42.38 N/mm2, strain was 0.3742,
ropes deformation was 35.17867 mm, elasticity was 114.1673 N/mm2 and
malleability was 37.42 %.
