The raw materials of the timber industry, especially furniture, are increasingly difficult to obtain in the quantity and quality needed. The development efforts carried out were utilizing Nipah coir waste as a raw material for making particle boards. Particle boards are panel boards made of wood particles or materials containing lignocellulose. Nipah plants contain 27.3% lignin and 36.5% cellulose which has the potential to be used as raw material for particleboard production. This study aims to reveal the physical and mechanical properties of particleboards made from Nipah fruit fibre with adhesive using tapioca flour. The making of particle board is done with a ratio of 90%: 10%, 80%: 20%, 70%: 30%, 60%: 40%, by giving a pressure of 100 kg / cm2. Particle testing is carried out according to the JIS A 5908 standard (2003). From this study, the optimum results were obtained in variations of 60%:40%. The particle physical properties which have an average density value of 1.15 gr / cm3 and an average moisture content of 5.8%. While the mechanical properties obtained by the value of Modulus of Elasticity an average of 21,188.93 kg / cm2. This shows the particle board variations of 60%: 40% produced to meet the JIS A 5908 (2003) standard. Based on the analysis of the quality variations 60%: 40% of particle boards can be recommended as raw materials for interior furniture.

The development of engineering materials has increased its use. Engineering material which is a combination of various materials that can be made into a product, namely particle board. Nypa plants have the potential to be used as engineering materials. Traditionally, the use of nypa fruit has been carried out by the community, but the skin or nypa fiber only becomes waste that is wasted and untapped. The development of a diversified technology process in the utilization of waste into engineering materials in the form of particle boards is very possible. The particle board innovation made from raw nypa fiber as an interior furniture material that has light strength and weight as a substitute for wood. The process of making particle boards with compacting and composition optimization methods is an effort to obtain new material that can be developed and has quality according to JIS A 5908 standard. Efforts to develop new materials with better performance to replace wood products as furniture. Through the improvement of process technology and the potential livelihoods of plant waste in obtaining advanced materials as raw material for innovation in the manufacture of particle board products based on the waste of nypa fruit fiber.

Tibarau sugar cane is a renewable energy plant that is very likely to be processed into solid fuel in the form of bio-briquettes. Development of bio-briquette tibarau as an effort in the effort of alternative fuels to reduce the energy of oil-fueled energy. In producing biobriquette tibarau fuel, which has a measurable quality and performance with its calorific value. The use of bio-briquettes tibarau is a potential in developing renewable energy to achieve national energy security. Through the process of making bio-briquette products with carbonization technology in the furnace at certain temperatures that occur in the increase of heat. From this study, the results were obtained in the form of developing a bio-briquette tibarau model which is recommended as an alternative fuel. Characteristics of bio- briquette of tibarau content using tapioca adhesive were 32270.26 k/kg at carbonization 3000C and composition percentage 80 : 20. While bio-briquettes tibarau by using damar adhesive amounted to 36943.08 kJ/kg. Carbonization temperature affects the calorific value of biobriquettes tibarau sugar cane. The carbonization process of briquettes developed into biobriquettes were very important in improving the performance of bio-briquette fuels.
