| dc.description.abstract | DETYARA IMANI: Ropes made from mother in law tongue fiber (Sansevieria
trifasciata laurentii), supervised by LUKMAN ADLIN HARAHAP and SAIPUL
BAHRI DAULAY.
Sansevieria is a plant that has variety of color and leaf form and can be
used as decorative plants. Fiber of Sansevieria has characteristics of not easily
fragile, shiny, long, and good quality. This study was aimed to make and to
examine the quality of rope made from mother in law tongue fiber (Sansevieria
trifasciata laurentii).
This research was conducted in April until September 2015 in the
Laboratory of Agricultural Engineering, Faculty of Agriculture and tensile test
was conducted at Research Laboratory, College of Engineering University of
North Sumatra, Medan, by literature study, spinning the rope using spinners
simple tool, tensile test and parameters observation. Parameters measured were
tensile strength, strain, elasticity, rope deformation, and flexing. Results of the
research indicated that each substance tested with the same weight produced
different string diameter. Average values of examinated ropes was 1,2 g weight,
diameter was 4,26 mm, length was 34 mm, elongation was 17,2159 mm,
maximum loaded was 659,2695 N, cross section was 14,31 mm2
, elongation at
break of tensile strength was 46,85 N/mm2
, strain was 0,5063, elasticity was
92,5322 N/mm2
, ropes deformation was 17,2159 mm and flexing was 50,63 % | en_US |
