Abstract

Biodegradable product is product that produced from natural fibre source such as pineapple leaf fibre. Pineapple fruits is one of the popular and delicious fruit especially in Malaysia. The problem is people only uses fruit, while its leaves are disposed of. The pineapple leaves have been wasted material. Pineapple leaves that has been burned can causes air pollution. The usage of plastics in nowadays can causes landfill problem. The aim for this research is to study the potential application of pineapple leaf fibre in industries sectors, to develop a biodegradable product from pineapple leaf fibre and to anaylse the mechanical strength and biodegradable of pineapple leaf fibre. There are several rough stages that should be followed to complete this research which are identifying the problems of the research, have some research on the previous researchers that related, select the material and machines involved along the manufacturing process, design a product using SolidWorks software which is mini tray prototype, through a mechanical testing and biodegradable testing on the composite products and then manufacture mini tray. There are two mechanical testing conducted in this research which tensile test and biodegradable test. The highest values of tensile test strength for sample PALF reinforced PP was 8.32189 MPa., while for sample of PALF reinforced tapioca starch was 1.40927 MPa. The highest value of Young’s Modulus for mixture of PALF with tapioca starch was 2890.40007 MPa, while for mixture of PALF with PP was 1088.41727 MPa. In biodegradable testing, the result shown there is a weight changes occurred for mixture of PALF reinforced with tapioca starch. But, for mixture of PALF reinforced PP, the biodegradable testing was conducted to proven either this mixture could be degraded in soil or vice versa. From the result, it proven that mixture of PALF with PP could not be degraded in soil due to PP characteristics which classified as polymer that can be degraded only through burning process. Bioplastics are degraded by various kind of microorganism. In this research, several things have been discussed such parameter of mixture, temperature and heating press time, types of mould used, and types of sample tensile test. The conclusion for this research is biodegradable product of mini tray from pineapple leaf fibre has successfully made, and the result of tensile test and biodegradable testing for every samples has been recorded successfully.
