Tali Serat Berbahan Dasar Serat Alami Tanaman Lidah Mertua (Sansevieria Trifasciata Laurentii)

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 %
