The research has been carried out to make and analyze the physical and mechanical properties of particle board from coffee husk waste and Low Density Polyethylene (LDPE) with hot pressing method. The composition of coffee husk and LDPE sample composition ranged from 0: 100, 30:70, 40:60, 50:50, 60:40 and 70:30. The physical test results showed that the density values ranged from 0.48-0, 9 gr / cm 3 and the maximum value of density with the addition of coffee husk particles was at a composition of 30:70 of 0.8 gr / cm3 while the water content values ranged between 10.5 -14% and the minimum water content value with the addition of coffee husk particles of 12.45% is in the composition 30:70. In mechanical testing, the MOR strength values ranged from 70.45-100.6 kgf / cm2 and the optimum value was in the composition of 60: 40. From the MOE test results ranged from 10.00.23-13.000.07 kgf / cm2. Where the maximum MOE value is in the composition of 60:40.
