“…This trend has gained popularity due to the abundant availability of natural fibers, low density, high porosity, environmental sustainability, renewability, cost-effectiveness, and good insulation properties [3][4][5]. Many research efforts have been devoted to exploring the potential of natural fibers as the primary material for manufacturing particleboards, including but not limited to coffee skin [6][7][8][9], coconut coir fiber [11], and palm wood [12]. Additionally, previous studies have demonstrated the feasibility of using natural fibers as acoustic panel materials, such as hemp fiber [13], sisal, sugarcane, and banana [14].…”

This study was conducted to determine the physical and mechanical properties of particleboard. Manufacture of particleboard utilizes raw materials of rice husk with epoxy resin. The composition variations of rice husk : Epoxy are, 82:18, 77:23, 72:28. The rice husk was soaked in 5% NaOH solution for 1.5 hours, then smoothed and filtered with a size of 20 mesh. After preparation, the rice husk and epoxy were mixed with their respective compositions. Then the hot forging process was carried out with a pressure of 25 kg/cm2 at a temperature of 140° C for 8 minutes. The results of density test was found from 0.703 - 0.712 g/cm3, the water absorption value from 7.12 % - 8.75% and the thickness expansion value from 11.5% - 19.4%. The compressive strength (MOR) values range from 56.105 -82.63 kgf/cm3 and the flexural strength (MOE) values range from 8695 kg/cm2 - 10470.49 kg/cm2.

Coffee waste is a by-product from processing coffee beans which has the potential to be used as a reinforcing feed material (concentrate) for ruminants. The waste of coffee fruit is physically quite large in composition, that is 48% of the pulp and the rest is waste. The disadvantages of this coffee waste to be used as feed are its high fiber content (21%), caffeine and tannin and its voluminous physical form. But all this can be overcome by fermentation using Aspergius Niger so as to increase its nutritional value. This research was carried out by making a feed composition including: P0 = 0% coffee husk waste (control) and 98.75% rice bran, P1 = 30% coffee husk waste and 68.75% rice bran, P2 = 60% coffee husk waste and 38.75 rice bran and P3 = 90% coffee husk waste and 8.75% rice bran. The variables observed were the physical characteristics of the feed wafer including: aroma, color and density and palability. Data was collected and analyzed using ANOVA and Duncan Range Test. The results showed the use of coffee husk waste should be used at a level of 30%, because it has a high palability value and low density and crumbs so it is easier for ruminant animals to consume.
