Perpaduan Serat Daun Nanas (Ananas Comosus) Dan Kitosan Sebagai Material Alat Penangkapan Ikan Ramah Lingkungan (Combination of Pineapple Leaf Fiber and Chitosan for Eco-friendly Fishing Gear Materials)

Abstract

The utilization of pineapple leaf materialfiber for an alternative fishing gear is a step of development to create eco-friendly fishing gear material. The pineapple leaf fib er was observed based on mechanical (breaking strength and elongation value) and physical characteristics (water contents and specific weight) to learn about force of its fiber as natural material for the fishing gear. There were two methods used in this study, such as concentrates factor and soaking time in chitosan. Chitosan concentrates and soaking times in respectively were 1, 1.5, 2% and 15, 30, 45 minutes. The test of mechanical and physical characteristic had been done in Engineering and Design of Wood Building Laboratory, Department of Engineering, Forest Product, Forestry Faculty, Bogor Agricultural University, then for the breaking strength and elongation value used Universal Testing Machine (UTM). The data were analyzed by Completely Randomize Factorial Design (CRFD). The results showed that pineapple leaf fiber consist of 1.095% of water contents and 1.005 for specific weight. Statistical analysis proved that breaking strength value of pineapple leaf fibers was affected by soaking time in chitosan. The best result of the breaking strength test was when the fiber soaked in chitosan with concentrate 1 % during 45 minutes with amount of breaking strength and elongation 34.84 kgf and 0.60 mm
