| Summary: | Fishing gear consists of natural materials (natural fibres) and synthetic materials (synthetic fibres). The advantage of using synthetic materials is more durable. Polyamide is one of the examples of synthetic materials or also known as nylon. The effectiveness of the material makes fishermen not spend much money on the treatment of fishing gear. It is necessary to consider all aspects that affect the stability to achieve high elasticity, such as breaking strength and elongation. The method of this study was descriptive analysis which refers to the SNI ISO 1806:2010 method. Data were collected in dry conditions with nets as a sample and 3, 6, 9, 12 months of the length time of net usage, and one sample fishing gear that has not been used as a control variable. Each treatment was repeated 10 times, and then the value of breaking strength and elongation were tested by using an autograph machine. The result of this study is the value of breaking strength of multifilament polyamide (PA), net decreases alongside with length time of net usage. The value of elongation of multifilament polyamide (PA), net also decreases alongside with net usage time. There is a strong relationship between length time of net usage and the value of breaking strength and there is a strong relationship between length time of net usage and the value of elongation.
