Five levels of filler loading with or without divinyl benzene DVB were designed. The influence of filler concentration could improve tensile strength TS up to the optimum condition ratio rPP BP 8 2 . The effect of the bamboo particle size showed that the TS increased as the size of the particle smaller. The effect of BP particle size showed that the bigger of its size gave better bio-degradation properties. The use of DVB for the synthesis of bio-composites showed more biodegradable than without DVB. Keywords biodegradable bio-composites recycled polypropylene bamboo powder 1. INTRODUCTION Polypropylene PP is generally utilized as packaging materials and has a great potential to become waste when it is not used anymore. This PP waste can be used to other useful product and will not contaminate the environment. This PP waste referred as recycled PP rPP has functional group CH- methine which is capable to react with other functional group.1 As a tropical plant bamboo grows easily in Indonesia. Part of the bamboo which commonly used is its bar.2 Bamboo bar mainly consists of cellulose besides hemicellulose and lignin. Cellulose has three polar free hydroxyl groups and two glycoside carbon groups.3 4 In this research BP has been .
