This paper reviews about the future of pineapple leaf paper by focusing on the properties and potential of pineapple leaf paper. Besides that, environmental issues and quality of pineapple leaf paper as compared with the existing paper in market are also discussed.

Safety product is created for workers, students, people and society to prevent from dangerous, harmful, injured also risks situation that can be occurs before, during and after works. The materials to produce the safety product must be strong, hard, good resistance, fast treatment and others characteristic that can be protect and prevent the user from the dangerous. Sometimes, the cost to produce the safety product is expensive because of the material to make the safety product become the good products.

This paper reviews the effect of radiation on the mechanical properties of WPC. WPC can be defined as mixture of wood in a polymer matrix. Composite that used in this research mainly consists of 40% polyethylene (PE), 50 % wood fiber and the rest is carbon black. The WPC were then irradiated and go through post extrusion process under required dose levels of 0, 50, 100, 150, 200 and 250 kGy with the aid of the electron beam treatment (EB). Soon after, the irradiated WPC then classified using a test called bending test which specify in third point bending test (ASTM D4761) along with scanning electron microscopy (SEM). It was checked that two factors are affected with the increasing dose level and they were ultimate strength and modulus of elasticity (MOE). Diagnosis on the morphology of polyethylene by the research found that there was significant difference between the radiated and irradiated surfaces.
