The greatness of the characteristics fiber pseudo stem outer layer of Musa acuminata origin lombok Indonesia as reinforcing polyester composite

Musa acuminata stem is an agricultural waste that has good economic potential. For this reason, efforts are needed to increase the saba banana tree not only as waste, but also its function into natural fiber raw materials for polyester matrix composite reinforcement. The purpose of study was determine characteristics fibre (MASF) from North Lombok Regency, Indonesia Country a reinforcement composites. In study, (specimen), taken pseudo acuminata, which consists three layers: outer, middle and inner stem. ratting process done mechanically using extraction machine. To remove impurities in fiber, alkaline treatment carried out, by soaking 24 hours 5 % NaOH solution. characteristics, scanning electron microscopy (SEM) test out MASF morphology analysis, chemical compound content testing, heat resistance tensile strength testing. results showed outer layer pseudo-stem strong character. Fiber different, between layers pseudo-stems. cellulose (73.12 %) higher than Fimbristylis globulosa, hemp, jute, rice straw, wheat seaweed, sorghum coir, alpha grass. Less resistant degradation because mass loss occurs at constant rate up 245 °C. highest MASF, it 40–50 cm base Its better other fibers so potential can be further developed polymer composites
