MAKE A ROPE BAT WITH WATER NOODLE VERIFICATION
She gives training, testing, and serves as expert witness on Wood Identification (ISO 17025: 2008), and she also becomes an Advisory Council for verification institution of Indonesian Timber Legality Assurance System (TLAS). She holds a Certificate of Competence from LSP Quantum HRM International (SNI ISO/IEC 17024:2012) as Research Reviewer and a Reviewer of Foreign Research Permit under the coordination of Indonesian Ministry of Research and Technology. More than 80 national and international publications and 13 Patents and Copyrights in anatomy and quality of lignocellulose material and non-destructive testing have been produced during her career (2007 – present). Ratih has her PhD in Wood Science from the University of Melbourne, Australia, and got her Bachelor and Master Degrees from IPB University. Her scientific interests are in wood anatomy, bamboo and rattan anatomy, wood quality, and non-destructive testing. She is the Head of Lignocellulose Anatomy Laboratory and Curator of Xylarium Bogoriense at Forest Products Research and Development Center - Research, Development, and Innovation Agency (FORDA), Ministry of Environment and Forestry based in Bogor, Indonesia. The other factors namely environmental conditions, method of transportation, storage time and conditions, and fiber extraction affect the size and quality of the natural fibers. Besides that, fiber anatomical characteristics vary between different and same species that affect on the density and mechanical properties. Higher cellulose content and crystallinity tend to result better strength properties of fiber while lignin is since versa. Natural fibers are easy to absorb water due to the presence of hemicellulose that give hydrophilic properties make them less compatible in the interaction with matrix with hydrophobicity properties. The microstructure and chemical compositions of fibers affect the mechanical properties with the fiber cross-sectional area is the most variable influencing the fiber strength. The natural fibers have low density and high strength to weight ratio and reduction make them potential as light weight composite and reinforcement materials. This review describes the characteristics, and potential uses of some natural fibers in order to improve their sustainability and economic values. Understanding the basic properties of natural fibers is important to determine the optimal intended uses for instance as high-quality bio-composite raw material.
