Abstract
One of the construction systems and structures to be learned by a designer or architect is the construction and long-span structures. Application of long-span structures using cable as the main buffer in Indonesia is considered late whereas in some developed countries have been well developed. The main factors which may be considered the cause of this case is the lack of material knowledge which is synthetic rope. Synthetic rope is considered as capable as steel cable on a small scale. This research is conducted for public and academics to know how far is the strength of synthetic rope for modeling compared to steel cable. The method used is an experimental method of empirical testing by the test material on the tools that have been provided. Additionally, content analysis method in literature source and previous research is also used to get the data needed. Experiments conducted did not show the detailed measurement accuracy but with a certain value limit that can be seen by the eyes and senses. Keywords: Strength of materials, synthetic rope

Summary
Temuan elastikitas dihubungkan dengan nama Robert Hooke, yang dikenal lewat karyanya tentang microscopy. Ambil sebuah tali dawai yang panjangnya 20, 30 atau 40 kaki, dan ikat bagian ujungnya dengan paku, dan ujung lainnya dipasang sebuah Timbangan (skala) untuk diberi pemberat. Ilustrasi Robert Hooke tentang pengujian pegas dan tali elastis sumber: Cowan, 1977. Dalam penelitian menghitung kekuatan benang nilon pada penelitian karakteristik benang pancing nilon menggunakan metode tarik juga menggunakan asas Hook (Kiay,2011) dengan percobaannya sebagai berikut : Tegangan dan regangan tali pancing nilon digunakan rangkaian alat sederhana berupa tali pancing nilan dengan digantung secara vertikal dengan ujung atas diikat dengan pangkal tali diberi beban yang berbeda-beda. Pada penelitian pengujian tarik (Wikana,2007) dilakukan pengujian tarik untuk mengetahi kuat tali rami, dengan cara memasang tali pada dua tumpuan jepit lalu ditarik hingga tali menjadi tegang tetapi beban masih menunjukan angka nol. Penelitian bahan pada beberapa uji coba kekuatan serat bahan menggunakan uji tarik sehingga diketahui batasan kekuatan keelastisan bahan tersebut sehingga, pada penelitian kekuatan serat pada tali tampar ini juga mengguanakan uji kekuatan tarik
